Description

heat transmitter

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

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

The air rapidly compressed by the supercharger becomes extremely high in temperature, which causes the volume to expand and the oxygen density to drop, resulting in a decrease in the charging efficiency in the cylinder. Therefore, the intercooler allows the high-temperature air compressed by the supercharger to be cooled, thereby enhancing the suction efficiency of the engine cylinder and improving the combustion efficiency, thereby improving the fuel efficiency.

The intercooler in this role can be divided into water-cooled type and air-cooled type according to the cooling method. Among these, the water-cooled intercooler 10 is similar in principle to the air-cooled intercooler, but differs from the air-cooled intercooler in that it cools the compressed air using cooling water or water of 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, which are spaced apart from each other by a predetermined distance. A first inlet pipe 40 and a first outlet pipe 50 formed in the first header tank 20 or the second header tank 30, respectively, through which air is introduced; A plurality of tubes (60) having both ends fixed to the first header tank (20) and the second header tank (30) to form air passages; And a pin (70) interposed between the tube (60); A cover member 80 accommodated in an assembly of the tube 60 and the pin 70 and opened at one side and the other side where one end of the tube 60 is located; And a second inlet pipe (41) and a second outlet pipe (51) formed on one side of the cover member (80) and through which the cooling water flows; .

On the contrary, the cooling water is passed through the inside of the tube, the heat exchanger core, in which the header tanks, the tube and the pin are assembled, is disposed inside and the case is formed so as to surround the core. To cool the air.

However, such a water-cooled intercooler can prevent the air from passing between the inside of the case and the outside of the core, so that the air passes all through the core, thereby improving the heat exchange efficiency. However, since the outer side of the case and the outer side of the core are spaced apart from each other in order to insert and assemble the core into the inside of the case, the air may be bypassed through the space between the case and the core to lower the heat exchange performance. Also, in order to fit the inside of the case and the outside of the core so as to be in close contact without being separated, the case needs to be formed into several pieces and assembled, so that the structure and assembly are complicated and the structural strength of the case may be lowered.

housing

700, 700 and the outer surface of the core portion 100 are spaced apart from each other. The core portion 100 is formed so as to be spaced apart from the outer side both sides of the core portion 100 and the inner side surfaces of the housing 700 in the longitudinal direction so that the core portion 100 extends from the upper side to the lower side through the opened upper side of the housing 700 And can be easily inserted and assembled inside the housing 700.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It goes without saying that various modifications can be made.

For example, although the sealing member 200 is described as being fixed to the core unit 100 in the above embodiment, the sealing member 200 may be fixed to either the core unit 100 or the housing 700 . At this time, it is preferable that the sealing member 200 is coupled to the housing 700 in a state where the sealing member 200 is fixed to the core portion 100 optimally. This is because it is easier for the sealing member 200 to be inserted into the housing 700 while being coupled to the core portion 100. [

In addition, the sealing member 200 may be formed with a plurality of lip seals 220 for improving the sealing ability.
