Fig. 1 is a front view of a hybrid ship cooler according to an embodiment of the present invention. As shown in fig. 1, the hybrid ship cooler includes a central cooling unit 10 and a plurality of equipment cooling units 20 integrated in the central cooling unit 10. FIG. 2 is a cross-sectional view of the hybrid marine cooler of FIG. 1 at A-A; fig. 3 is a cross-sectional view of the hybrid ship cooler shown in fig. 1 at B-B. As shown in fig. 2 and 3, the central cooling unit 10 includes a housing and a plurality of heat exchange pipes laid in the housing. Seawater is circulated in the heat exchange tubes as cooling water, high-temperature fresh water is circulated in the shell, the heat exchange tubes and the equipment cooling unit 20, and low-temperature fresh water is discharged after heat exchange between the high-temperature fresh water and the seawater and is used for cooling ships. Each equipment cooling unit 20 includes a housing and a plurality of heat exchange tubes disposed within the housing for cooling a high temperature fluid discharged from equipment to be cooled connected thereto. Each equipment cooling unit 20 is connected to a device to be cooled, which may be a compressor, a lubricating oil pump, a fuel pump, etc. The heat exchange tubes in the equipment cooling unit 20 also circulate pumped seawater and use the seawater as cooling water, high-temperature fluid such as high-temperature steam and high-temperature water discharged by equipment to be cooled flows in the space between the shell and the heat exchange tubes, and the high-temperature fluid is cooled after heat exchange with the seawater. One end of the central cooling unit 10 is provided with an outlet end socket 30, and the other end is provided with an inlet end socket 40; the outlet head 30 and the inlet head 40 are conventional in the art, and the specific connection relationship will not be described.

As shown in fig. 1, the hybrid ship cooler provided in the embodiment of the present invention further includes a plurality of baffles 50, and the plurality of baffles 50 are disposed in one-to-one correspondence with the plurality of equipment cooling units 20. The baffle 50 is rotatably installed in the outlet head 30, a plurality of through holes are formed in the baffle 50, and along with the rotation of the baffle 50, the axes of at least part of the through holes can coincide with the axes of the heat exchange tubes in the equipment cooling unit 20. It should be noted that the number of the through holes may be greater than the number of the heat exchange tubes in the equipment cooling unit 20, or may be less than or equal to the number of the heat exchange tubes in the equipment cooling unit 20, and the embodiment of the present invention is not particularly limited.

In the composite ship cooler, after the baffle 50 rotates, the corresponding relation between the through holes on the baffle and the heat exchange tubes changes. It should be noted that the baffle 50 does not block the cooling water flowing out from the heat exchange tubes in the central cooling unit 10. That is, during the rotation of the baffle 50, the projection of the baffle 50 onto the longitudinal section of the central cooling unit 10 corresponds only to the respective equipment cooling unit 20. The longitudinal direction of the central cooling unit 10 refers to a direction parallel to the end surface of the housing of the central cooling unit 10, and the lateral direction refers to the longitudinal direction of the central cooling unit 10. Specifically, at a certain position, the hole axis of the through hole overlaps with the axis of the heat exchange tube, at this time, the blocking effect of the baffle 50 is minimal, and the cooling water in the heat exchange tube rapidly flows out along the through hole, which is defined as the closed position of the baffle 50. When the demand of cooling water in the equipment cooling unit 20 is reduced, the baffle 50 is rotated, and the baffle 50 blocks the cooling water discharged from the heat exchange pipes in the corresponding equipment cooling unit 20, so that the outlet flow resistance of the cooling water in the equipment cooling unit 20 is increased, and the outlet flow resistance of the cooling water in the central cooling unit 10 is basically unchanged, thereby adjusting the distribution of the flow rate of the cooling water between a plurality of equipment cooling units 20 and the central cooling unit 10 to adapt to different working conditions.

According to the composite ship cooler provided by the embodiment of the invention, the central cooling unit 10 is integrated with the plurality of equipment cooling units 20, and each equipment cooling unit 20 can be connected with equipment to be cooled, so that the number of ship coolers distributed in a ship can be reduced, and the problem that the existing ship coolers are distributed dispersedly is solved; the integrated arrangement of the central cooling unit 10 and the equipment cooling unit 20 can reduce the modal frequency of the central cooling system, reduce resonance, and effectively attenuate vibration noise. In addition, a baffle 50 is arranged in the outlet end socket 30, and the cooling water flow distribution between the central cooling unit 10 and the equipment cooling unit 20 can be adjusted by virtue of the rotatably arranged baffle 50 so as to adapt to different working conditions.

The plurality of baffles 50 corresponding to the plurality of equipment cooling units 20 may be adjusted simultaneously or individually. When the synchronous adjustment is performed, the required amount of cooling water in each corresponding facility cooling unit 20 changes uniformly. When adjusted individually, the flow of cooling water into the cooling units 20 of different equipment may be adjusted as needed to meet the needs of different equipment to be cooled.

For example, there are two equipment cooling units 20, i.e., a first cooling unit and a second cooling unit. When the two baffles 50 corresponding to the first cooling unit and the second cooling unit are both in the closed position, the flow of cooling water distributed by the heat exchange pipes in the first cooling unit and the second cooling unit is the largest. If the flow demand of the seawater cooling water in the first cooling unit is reduced, the corresponding baffle 50 in the first cooling unit is turned on independently, and the flow of the cooling water distributed in the second cooling unit and the central cooling unit 10 is increased; similarly, if the flow demand of the cooling water in only the second cooling unit decreases, the corresponding damper 50 in the second cooling unit is turned on alone, and correspondingly, the flow of the cooling water distributed to the first cooling unit and the central cooling unit 10 increases; if the flow demand of the cooling water in both the first and the second cooling unit decreases, the corresponding shutters 50 are simultaneously or individually turned on, and the flow of the cooling water distributed only by the central cooling unit 10 increases.

Specifically, as shown in fig. 1, an inlet end plate 11 and an outlet end plate 12 are fixedly mounted on a housing of the central cooling unit 10, two ends of the plurality of equipment cooling units 20 are respectively fixedly mounted on the inlet end plate 11 and the outlet end plate 12, and heat exchange pipes in the central cooling unit 10 are mounted on the inlet end plate 11 and the outlet end plate 12. The inlet end plate 11 is provided with water inlets corresponding to the central cooling unit 10 and the heat exchange tubes in the equipment cooling units 20, and seawater enters the inlet end socket 40 and then dispersedly enters the heat exchange tubes from the water inlets; the outlet end plate 12 is provided with water outlets corresponding to the heat exchange pipes in the central cooling unit 10 and the equipment cooling units 20, so that the heated cooling water can be discharged from the heat exchange pipes. When the baffle 50 is in the closed state, at least part of the through hole is coaxial with the water outlet.

On the basis of the above embodiment, the through holes and the water outlets are arranged in a one-to-one correspondence manner, that is, the number of the through holes is consistent with the number of the heat exchange tubes in the corresponding equipment cooling unit 20, so that the number of hole structures to be processed of the baffle 50 is optimized, and the processing cost is reduced.

Wherein each baffle 50 has a shape corresponding to a cross-sectional shape of the corresponding equipment cooling unit 20. For example, the housing of the device cooling unit 20 is cylindrical, and correspondingly, the baffle 50 is a circular plate.

On the basis of any of the above embodiments, when the baffle 50 is in the closed position, the axis of the through hole coincides with the axis of the heat exchange tube in the corresponding equipment cooling unit 20, and at this time, the baffle 50 is parallel to the end face of the equipment cooling unit 20, that is, the baffle 50 extends in the longitudinal direction of the equipment cooling unit 20.

Wherein, the edge of the baffle 50 is protruded or fixedly connected with a rotating shaft, and the rotating shaft extends out of the shell of the central cooling unit 10 and is rotatably connected with the shell. When the plurality of baffles 50 are synchronously adjusted, the plurality of baffles 50 can be fixed with each other and adjusted by a rotating shaft; of course, each of the plurality of baffles 50 or a part of the baffles 50 may be protruded or fixedly connected with a rotating shaft, and the synchronous swing of the plurality of baffles 50 is realized by the synchronous adjustment of the rotating shaft. When the plurality of baffles 50 are individually adjusted, each baffle 50 is protruded or fixedly connected with the rotating shaft. Preferably, each baffle 50 is provided with a protruding or fixed connection to the rotating shaft, so that the baffles can be adjusted synchronously or individually as required. The extension direction of the rotating shaft can be along the length direction of the central cooling unit 10, and at the moment, the outlet flow resistance is adjusted by means of the corresponding areas of the through holes and the pipe orifices of the cooling pipes; of course, the extension direction of the rotation shaft may also be parallel to the end surface of the central cooling unit 10, and in this case, the rotation baffle 50 may also adjust the corresponding area of the through hole and the cooling pipe orifice, and thus the outlet flow resistance. When the extending direction of the rotating shaft is parallel to the end face of the central cooling unit 10, the swing direction of the baffle 50 coincides with the flow direction of the cooling water. Like this, a plurality of baffles 50 all swing back edge cooling water flow direction and be the convergent form, help quick discharge cooling water, improve cooling efficiency.

In order to improve the stability of the rotation, two rotation shafts are provided on each baffle 50, and the two rotation shafts are oppositely disposed on the baffle 50. When the barrier 50 is a circular plate, two rotation shafts are arranged at both ends of a certain diameter of the barrier 50.

Wherein, the rotating shaft is connected with an external rotating drive to realize automatic control. Of course, the flow distribution can also be adjusted manually.

Two equipment cooling units 20 are provided, and the two equipment cooling units 20 are arranged symmetrically with respect to the axis of the housing of the central cooling unit 10.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
