Technical field

The present invention relates to a kind of heat exchangers for internal combustion engine.In addition, the present invention relates to one kind to have this heat exchange The internal combustion engine of device.

Background technique

Boosting internal combustion engine is more and more important in modern motor, because being based on work with the help of this pressurization Volume (Hubraum) and power density based on fuel consumption can dramatically increase.Accordingly, there exist such trend: having and closes The smaller and smaller engine of suitable supercharging device is to increase its power output or reduce fuel consumption.Another observed becomes Gesture is to be reduced the size of engine with identical power output and also reduced its fuel consumption.Therefore, boosting internal combustion engine is logical Often equipped with heat exchanger, so as to the cooling pressurization being pressurized by corresponding supercharging device (such as discharge gas turbocharger) Air.Pressurized air such cooling increases the power outputs of internal combustion engine, reduce the fuel consumption and pollutant of internal combustion engine Discharge, and reduce the thermic load of internal combustion engine.

10 2,012 008 700 A1 of DE discloses the heat exchanger of such as charger-air cooler form, wherein compressing Pressurized air it is cooling at least two grades (Stufen) adjacent to each other by means of cooling liquid.For pressurized air, mention For flow channel and coolant flowpaths.Heat exchanger is formed by the monoblock type plate individually stacked.

Traditional charger-air cooler is typically implemented as heat exchanger, which is a part of coolant circuit And coolant is flowed by the heat exchanger, and coolant is thermally coupled to pressurized air to be cooled again.It is mentioned from pressurized air The heat taken is absorbed by coolant.

Along stacking direction, heat exchanger includes the tubular body of arrangement of overlieing one another, and pressurized air to be cooled can lead to Cross the tubular body flowing.Coolant channel is set between each tubular body, and coolant is flowed by the coolant channel. In other words, coolant channel and tubular body replace along stacking direction.In general, pass through the coolant path of conventional heat exchanger Stream is so-called " Z-type stream (Z-flow) " or " U-shaped stream (U-flow) ", and wherein coolant flows through entrance and by outlet outflow.

However, in this traditional heat exchanger, due to usually because of the asymmetry of coolant and flowing mould heterogeneous Non-uniform refrigerant distribution caused by formula, and due to deeper coolant path, it can occur in the coolant channels Boiling of the coolant in so-called dead stream region even occurs for inefficient heat transmitting.Water conservancy diversion is used in addition, especially working as When plate guides the coolant in coolant path, the undesirable pressure loss in coolant circuit frequent occurrence.On the contrary, working as When in order to avoid the above problem, using the sufficiently small heat exchanger of multiple sizes, this measure is along with the need to installation space The increase of the quantity of the increase and required component asked.

Summary of the invention

It, should compared with conventional heat exchanger therefore, the purpose of the present invention is to create a kind of improvement embodiment of heat exchanger Heat exchanger is characterized in that the flowing for improving coolant by coolant path, to be avoided as much as especially extremely flowing The formation in region and the boiling of the coolant associated with it.Meanwhile heat exchanger design compactness and can be cost-effective Mode produces.

Solves the purpose being previously mentioned by subject matter of the independent claims.Preferred embodiment is the master of dependent claims Topic.

Therefore, basic conception of the invention is: (i.e. additional by the second (i.e. additional) coolant distributor and second ) coolant collecting device supplement equipped with the first coolant distributor and the first coolant collecting device heat exchanger so that volume Outer the second coolant distributor and the second additional coolant collecting device respectively with the first coolant distributor and first Coolant collecting device is arranged substantially oppositely, and is assigned the first and second coolant paths of fluid separation each other.Cause This, largely or entirely avoids the formation in dead stream region, and coolant can be conducted through corresponding coolant path.With This mode particularly prevents the undesirable boiling of coolant.

Therefore, the heat exchanger according to the present invention proposed here ensures improved and more effective heat transmitting.Here The heat exchanger according to the present invention proposed may be used as the charger-air cooler with compact design, hence for vehicle The arrangement of charger-air cooler or heat exchanger in, it is only necessary to retain very small installation space.Simultaneously as its is non- Normal simple design structure, the heat exchanger introduced here can readily produce, this generates cost advantage in the fabrication process.
