Description

Fixing structure of intercooler for a car}

The present invention relates to an intercooler mounting structure of an automobile, and more particularly, to an intercooler mounting structure of an automobile capable of improving the performance of an automobile condenser and a radiator.

Fig. 1A is a schematic diagram showing a mounting structure of an intercooler 10 ', a condenser 20' and a radiator 30 'of a conventional vehicle.

As shown in the drawing, when the intercooler 10 'is mounted in front of an engine room of a vehicle, a condenser 20' and a radiator 30 'are mounted in turn.

Here, the intercooler 10 'is a device installed between a compressor and an intake manifold to cool air in an engine equipped with a supercharger (turbo charge), and the condenser 20' converts gas or vapor into a liquid. The giving device is part of the air conditioning system and, in addition, the radiator 30 'is a device for cooling the cooling water heated in the engine.

As shown, in order to mount the condenser 20 'and the radiator 30' in the engine room, a mounting structure 11 'is formed on the front surface of the intercooler 10' to enable three-point support. Of course, other structures corresponding to the mounting structure 11 'of the intercooler 10' should be installed in the engine room. In the figure, reference numeral 31 'is a lower mounting part for supporting the radiator 30' in the engine room.

1B is a schematic diagram illustrating a cooling state by the mounting structure of the intercooler 10 ', the condenser 20', and the radiator 30 '.

As shown, the outside air temperature before passing through the intercooler 10 'is about 43 ° C, and after passing through the intercooler 10', it becomes about 60 ° C. In addition, the air temperature passing through the interior of the intercooler 10 'is approximately 140 ~ 170 ℃.

Subsequently, the air temperature passing through the condenser 20 'is about 70 deg. C, and the refrigerant temperature passing through the inside of the condenser 20' is about 60 to 80 deg.

In addition, the air temperature passing through the radiator 30 'is approximately 90 ° C, and the cooling water temperature passing through the inside of the radiator 30' is approximately 100-107 ° C.

However, due to the mounting structure of the intercooler and the arrangement of the intercooler, the condenser and the radiator, various problems occur as follows.

First, since there must be a separate mounting structure in the engine room and the intercooler, there is a problem of increasing the weight and the number of parts as well as the cost increases.

Second, since the intercooler must be assembled separately from the line, there is a problem that the line productivity and assembly man-hours increase.

Third, there is a problem that the cooling performance deteriorates (decreases the thermal efficiency). That is, because the condenser is located in the rear of the intercooler due to the mounting structure, the temperature of the inlet air that exchanges heat with the condenser rises from an outside temperature of 43 ° C. to 60 ° C., which worsens the heat dissipation of the condenser. It rises further and lowers the performance of the capacitor, which is fatal to the cooling performance.

Fourth, there is a problem that the cooling performance deteriorates (decreases the thermal efficiency). In other words, it increases the air temperature flowing into the radiator rather than without the intercooler, which deteriorates the radiator's heat dissipation (efficiency deterioration). Fatal to

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention to provide an intercooler mounting structure of a vehicle that can improve the performance of the condenser and the radiator of the vehicle.

Second, with the intercooler already installed in the radiator, the radiator is put into the production line, thereby improving line productivity and reducing assembly labor.

Third, the cooling performance of the vehicle is improved. That is, the intercooler is located on the lower surface of the condenser and heat exchanges directly with the condenser at approximately 43 ° C., so that heat exchange is more efficient than in the conventional front position.

Fourth, the cooling performance of the vehicle is improved. That is, the intercooler is located on the lower surface of the radiator, and the air temperature flowing into the radiator passes only through a condenser having a low heat dissipation temperature, thereby improving heat exchange efficiency of the radiator due to the decrease in the inlet air temperature. That is, the outside air temperature passing through the intercooler and the condenser reaches approximately 70 ° C. at an inclination condition of 7% gradient at approximately 43 ° C., but the air temperature passing only the condenser is about 60 ° C., which is relatively low. In addition, the ventilation resistance is also small, thereby improving the heat exchange performance according to the increased driving wind injection amount.

Fifth, since the hot heat exchanger is located in a separate lower region and the air temperature flowing into the condenser and the radiator is lowered, the heat radiation amount is increased (efficiency increase).
