Detailed Description

< this embodiment > [ state where the sub-tank 2 is installed in the vehicle ]

Fig. 1 is a diagram showing a state in which a sub tank 2 of the present embodiment is installed in a vehicle. Fig. 2 is an enlarged view of the area a of fig. 1. Fig. 3 is a schematic diagram of a cooling water path. Fig. 4 is a diagram showing the structure of the sub-tank 2. Fig. 4 is a view showing a structure of the sub-tank 2 shown in fig. 2 when viewed from the direction B. Fig. 5 is a view showing a structure of the sub-tank 2 shown in fig. 4 when viewed from the direction C. Fig. 6 is a view showing a structure of the sub-tank 2 shown in fig. 4 when viewed from the direction D. Fig. 7 is a view showing a structure of the sub-tank 2 shown in fig. 4 when viewed from the direction E.

The vehicle has a water-cooled intercooler 1, an auxiliary tank 2, a radiator 3, a pump 4, a storage tank 5, and a hose 6. As shown in fig. 3, the water-cooled intercooler 1, the sub-tank 2, the radiator 3, the pump 4, the storage tank 5, and the hose 6 constitute a cooling water path.

The water-cooled intercooler 1 cools the combustion air by exchanging heat between the heat medium and the air circulated from the turbocharger (hereinafter referred to as "combustion air"). The heat transport medium contains a liquid that cools at least 1 of the units of the vehicle. The heat transport medium is, for example, cooling water. The unit of the vehicle is, for example, a water-cooled intercooler 1. The turbocharger has the following functions: the density of the combustion air flowing into the engine is increased by the flow of the exhaust gas discharged from the engine. Since heat is taken away from the combustion air by heat exchange with the combustion air, the temperature of the heat transmission medium at the outlet of the water-cooled intercooler 1 is higher than the temperature of the heat transmission medium at the inlet of the water-cooled intercooler 1.

The sub-tank 2 is a container that contains a heat transport medium. The sub-tank 2 is provided downstream of the water-cooled intercooler 1, for example. Details of the sub-tank 2 will be described later.

The radiator 3 cools the heat transport medium by exchanging heat between air blown by traveling wind or a fan and the heat transport medium circulating from the sub-tank 2. The radiator 3 is provided downstream of the sub-tank 2, for example. Since heat is taken away by the air blown by the traveling wind or the fan by heat exchange with the air blown by the traveling wind or the fan, the temperature of the heat transport medium at the outlet of the radiator 3 is lower than the temperature of the heat transport medium at the inlet of the radiator 3.

The pump 4 has a function of pumping the heat transport medium. The pump 4 is provided, for example, downstream of the radiator 3, i.e., between the radiator 3 and the water-cooled intercooler 1.

The heat transfer medium circulates in the order of the water-cooled intercooler 1, the sub-tank 2, the radiator 3, and the pump 4. The heat transfer medium passes through the water-cooled intercooler 1, and the temperature thereof increases, and passes through the radiator 3, and the temperature thereof decreases.

The reservoir tank 5 is a container for accommodating a heat transfer medium that circulates between an engine and a radiator, not shown. As described later, the sub-tank 2 is connected to the storage tank 5 via the 5 th hose 65.

The hose 6 is a medium conveying member that flows a heat conveying medium between a plurality of devices in the vehicle. The hoses 6 include a 1 st hose 61, a 2 nd hose 62, a 3 rd hose 63, a 4 th hose 64, a 5 th hose 65, and a 6 th hose 66. The 1 st hose 61 flows the heat transfer medium from the water-cooled intercooler 1 to the sub-tank 2. The 2 nd hose 62 flows the heat transport medium from the sub-tank 2 to the radiator 3. The 3 rd hose 63 flows the heat transport medium from the radiator 3 to the pump 4. A 4 th hose 64 flows the heat transfer medium from the pump 4 to the water-cooled intercooler 1. The 5 th hose 65, for example, allows the heat transfer medium to flow from the sub tank 2 to the storage tank 5. The 6 th hose 66, for example, allows the heat transfer medium to flow from the sub-tank 2 to the radiator 3.

[ detailed construction of the sub-tank 2 ]

The sub-tank 2 includes a housing portion 21, a 1 st inflow portion 22, a 1 st outflow portion 23, a 2 nd inflow portion 24, a 2 nd outflow portion 25, a supply portion 26, and a lid portion 27.

The accommodating portion 21 accommodates a heat transport medium. The accommodating portion 21 has an inclined portion 211, a 1 st accommodating portion 212, and a 2 nd accommodating portion 213. The inclined portion 211 is inclined upward toward the 2 nd outflow portion 25. Specifically, the inclined portion 211 is formed as: as the distance approaches the 2 nd outflow portion 25, the length of the horizontal plane passing through the 1 st inflow portion 22 gradually increases in a state where the housing portion 21 is mounted in the vehicle.

The inclined portion 211 is formed, for example, as indicated by the broken line arrows shown in fig. 4 to 7: the inner side surface of the upper surface of the accommodating portion 21 in the vehicle height direction has a gradient of a predetermined angle with the horizontal direction orthogonal to the vehicle height direction toward the 2 nd outflow portion 25. The predetermined angle is, for example, 4 °, but may be any other angle.

The inclined portion 211 may be a flat surface or a curved surface. The inclined portion 211 has a curved surface whose curvature changes continuously, for example, as follows: the predetermined angle formed with the horizontal direction orthogonal to the height direction of the vehicle gradually becomes larger toward the 2 nd outflow portion 25.

Since the housing portion 21 has the inclined portion 211 in this way, the gas contained in the heat transport medium inside the housing portion 21 easily flows along the inner surface of the inclined portion 211 toward the 2 nd outflow portion 25.

The 1 st accommodation part 212 has the 1 st inflow part 22 and the 1 st outflow part 23. The 2 nd accommodating portion 213 is located above the 1 st accommodating portion 212 in the height direction of the vehicle in a state where the sub tank 2 is mounted to the vehicle, and has a cross-sectional area smaller than a cross-sectional area of the 1 st accommodating portion 212 in the horizontal direction in a state where the sub tank 2 is mounted to the vehicle.

By locating the housing portion 21 above the 1 st housing portion 212 in the height direction of the vehicle and having a cross-sectional area smaller than the cross-sectional area of the 1 st housing portion 212 in the horizontal direction in a state where the sub-tank 2 is mounted on the vehicle in this manner, the heat transport medium capacity can be secured and the degree of freedom of layout can be improved, compared to the sub-tank 2 in a rectangular parallelepiped shape, for example. That is, since the housing portion 21 has such a shape, even when it is necessary to dispose other equipment in the vicinity of the sub-tank 2, it is possible to dispose other equipment in the vicinity of the sub-tank 2 without reducing the capacity of the sub-tank 2.

In the sub-tank 2, the 1 st inflow portion 22 and the 1 st outflow portion 23 are provided in the 1 st accommodation portion 212 located below the 2 nd accommodation portion 213. Therefore, since the position where the heat transport medium flows into the housing portion 21 can be set to a position close to the bottom surface, the heat transport medium flowing into the housing portion 21 from the 1 st inflow portion 22 in the sub tank 2 is less likely to flow into the housing portion 21 from above the liquid surface of the heat transport medium housed in the housing portion 21. As a result, in the sub-tank 2, bubbles are less likely to be generated in the housing portion 21 by the heat transport medium flowing in from the 1 st inflow portion 22.

The 1 st inflow portion 22 causes the heat transport medium flowing out of at least 1 of the units to flow into the accommodating portion 21. Specifically, the 1 st inflow portion 22 causes the heat transfer medium flowing out of the water-cooled intercooler 1 to flow into the housing portion 21. More specifically, the 1 st inflow portion 22 has an opening for allowing the heat transport medium to flow into the accommodating portion 21. The 1 st inflow portion 22 is, for example, a cylindrical portion to which the 1 st hose 61 is attached.

The 1 st outflow portion 23 causes the heat transport medium that has flowed into the housing portion 21 from the 1 st inflow portion 22 to flow out of the housing portion 21. Specifically, the 1 st outflow portion 23 causes the heat medium flowing out of the housing portion 21 to flow out to the heat sink 3. More specifically, the 1 st outflow portion 23 has an opening for allowing the heat transport medium to flow out of the housing portion 21. The 1 st outflow portion 23 is, for example, a cylindrical portion to which the 2 nd hose 62 is attached.

The 2 nd inflow portion 24 causes the gas contained in the heat transport medium flowing out of the heat sink 3 to flow into the housing portion 21. Specifically, the 2 nd inflow portion 24 causes the air flowing out of the radiator 3 to flow into the housing portion 21. More specifically, the 2 nd inflow portion 24 has an opening for allowing the gas contained in the heat transport medium to flow into the housing portion 21. The 2 nd inflow portion 24 is, for example, a cylindrical portion to which the 6 th hose 66 is attached.

The 2 nd outflow portion 25 is provided above the 1 st inflow portion 22 in the height direction of the vehicle. The 2 nd outflow portion 25 is provided at a position higher than the 1 st inflow portion 22 and the 1 st outflow portion 23, for example. The 2 nd outflow portion 25 causes the gas contained in the heat transport medium to flow out of the housing portion 21. The gas contained in the heat transport medium is, for example, air. Specifically, the 2 nd outflow portion 25 causes the heat transfer medium flowing out of the housing portion 21 to flow out to the storage tank 5. More specifically, the 2 nd outflow portion 25 has an opening for allowing the heat transport medium to flow out of the housing portion 21. The 2 nd outlet 25 is, for example, a cylindrical portion to which the 5 th hose 65 is attached.

The 2 nd outflow portion 25 is formed at a position closer to the 1 st inflow portion 22 than the 1 st outflow portion 23. Specifically, the 2 nd outflow portion 25 is formed at a position where the length between the 2 nd outflow portion 25 and the 1 st inflow portion 22 is smaller than the length between the 2 nd outflow portion 25 and the 1 st outflow portion 23. Since the 2 nd outflow portion 25 is provided in this manner, the gas contained in the heat transport medium flowing from the 1 st inflow portion 22 into the housing portion 21 in the sub tank 2 easily flows out from the inside of the housing portion 21 through the 2 nd outflow portion 25.

The supply unit 26 supplies the heat transport medium to the housing unit 21. Specifically, the supply portion 26 has an opening for flowing the heat transport medium into the housing portion 21. The supply portion 26 is, for example, a cylindrical portion. The lid 27 is a member that covers the opening of the supply unit 26. The user removes the lid 27 from the supply unit 26 and causes the heat transport medium to flow into the inside of the housing unit 21 from the opening of the supply unit 26.

Comparative example

Fig. 8 is a diagram showing a structure of a conventional sub-tank 9. Fig. 9 is a view showing a structure of the sub-tank 9 shown in fig. 8 when viewed from the direction F. Fig. 10 is a view showing a structure of the sub-tank 9 shown in fig. 8 when viewed from the G direction.

As shown in fig. 8 to 10, the inner surface of the upper surface of the housing portion 91 of the sub-tank 9 has a horizontal surface. Thus, as shown in fig. 8, for example, there is a risk that: air will accumulate in the area indicated by area H in the figure. The air accumulated in the region H flows out from the 1 st outflow portion 93. As a result, the cooling performance of the water-cooled intercooler 1 may be reduced because air may enter the cooling water path.

In contrast, since the sub-tank 2 has the inclined portion 211 as described above, air is less likely to accumulate inside the housing portion 21. As a result, the following can be prevented: the air flows inside the cooling water path, and the cooling performance of the water-cooled intercooler 1 is reduced.

[ Effect of the sub-tank 2 of the present embodiment ]

The sub-tank 2 of the present embodiment includes: an accommodating portion 21 that accommodates a heat conveyance medium containing a liquid that cools at least 1 of the units of the vehicle; a 1 st inflow portion 22 that causes the heat transportable medium flowing out of at least 1 of the cells to flow into the accommodating portion 21; a 1 st outflow portion 23 that causes the heat conveyance medium that flows into the housing portion 21 from the 1 st inflow portion 22 to flow out of the housing portion 21; and a 2 nd outflow portion 25 that is provided above the 1 st inflow portion 22 in the height direction of the vehicle and that causes the gas contained in the heat conveyance medium to flow out of the housing portion 21. In addition, the accommodating portion 21 is formed with an inclined portion 211 inclined upward toward the 2 nd outflow portion 25.

In the sub-tank 2 of the present embodiment, since the inclined portion 211 inclined upward toward the 2 nd outflow portion 25 is formed in the housing portion 21 in this manner, air can be made less likely to accumulate inside the sub-tank 2. Therefore, the sub-tank 2 can prevent the heat conveyance medium flowing in the cooling water path from containing air, and the flow of the heat conveyance medium containing air. As a result, the sub-tank 2 can prevent the cooling performance of the water-cooled intercooler 1 from being lowered.

In the above embodiment, the heat transfer medium flowing out of the water-cooled intercooler 1 is assumed to flow into the sub-tank 2, but the present invention is not limited thereto. The sub tank 2 may be a tank for accommodating a heat transfer medium in a vehicle. The sub tank 2 may be configured such that the heat transport medium flowing out of the device for cooling the object with the heat transport medium flows in, and the sub tank 2 may be configured such that the heat transport medium flowing out of the engine flows in, for example.

Although the present disclosure has been described above with reference to the embodiments, the technical scope of the present disclosure is not limited to the scope described in the above embodiments, and various modifications and changes can be made within the scope of the present disclosure. For example, the embodiments of the distribution and integration of the apparatuses are not limited to the above embodiments, and all or a part of them may be configured to be functionally or physically distributed and integrated in arbitrary units. In addition, a new embodiment generated by any combination of the plurality of embodiments is also included in the embodiments of the present disclosure. The effect of the new embodiment by the combination has the effect of the original embodiment.

The present application is based on the japanese patent application (japanese application 2018-146473) filed on 8/3/2018, the contents of which are hereby incorporated by reference.

Industrial applicability

According to the present disclosure, since the effect of making the air less likely to accumulate inside the sub-tank is obtained, it is useful in preventing the air from flowing inside the cooling water passage and causing a reduction in cooling performance of the water-cooled intercooler.
