Description

Heat exchanger {Heat exchanger}

The present invention relates to a heat exchanger, and to a heat exchanger capable of cooling air compressed at high temperature and high pressure by a supercharger to increase the output of an engine.

Among the heat exchangers, the intercooler is a device that cools air compressed at high temperature and high pressure by a supercharger to increase engine output.

The temperature of the air rapidly compressed by the supercharger is very high, so that the volume expands and the oxygen density decreases, resulting in a decrease in the filling efficiency in the cylinder. Therefore, the intercooler cools the high-temperature air compressed in the supercharger, thereby increasing the suction efficiency of the engine cylinder and improving the combustion efficiency, thereby increasing the fuel economy.

Intercoolers that play this role can be divided into water cooling and air cooling according to the cooling method. Among these, the water-cooled intercooler 10 is similar in principle to the air-cooled intercooler, but differs in that it cools the compressed air using coolant or water from the vehicle instead of outside air when cooling the intercooler through which hot air passes. .

The water-cooled intercooler 10 shown in FIG. 1 includes: a first header tank 20 and a second header tank 30 spaced apart from each other and formed in parallel; A first inlet pipe 40 through which air is introduced and a first outlet pipe 50 formed in the first header tank 20 or the second header tank 30, respectively; A plurality of tubes 60 having both ends fixed to the first header tank 40 and the second header tank 50 to form an air passage; And a pin 70 interposed between the tube 60. A cover member 80 that accommodates the assembly of the tube 60 and the pin 70 and opens at one side and the other side at which one end of the tube 60 is positioned; And a second inlet pipe 41 and a second outlet pipe 51 formed on one side of the cover member 80 to allow cooling water to flow therein. It is formed including.

In addition, on the contrary, the cooling water passes through the inside of the tube, and the heat exchanger core, which is an assembly of header tanks, tubes, and fins, is placed inside and a housing is formed to surround the core, while air passes through the inside of the housing. It may be configured to cool the air by.

However, such a water-cooled intercooler prevents air from passing between the inner side of the case and the outer side of the core, so that all the air passes through the core, thereby improving heat exchange efficiency. However, in order to insert and assemble the core into the case, there must be a gap so that the outer side of the case and the outer side of the core are spaced apart, so that air is bypassed through the spaced space between the case and the core, thereby deteriorating heat exchange performance. Alternatively, in order for the inner side of the case and the outer side of the core to be in close contact without being separated from each other, the case must be formed into several pieces and then assembled, so that the structure and assembly are complicated, and the structural strength of the case may be reduced.
