The present invention relates to an intercooler device of a vehicle, and more particularly, to an intercooler device that is provided in a vehicle cooling system and supplies low-temperature air so as to improve combustion efficiency of an engine.

In general, the vehicle is provided with a cooling system that cools the engine in operation to maintain the engine temperature properly, and the cooling method is largely air-cooled and water-cooled. The temperature of the gas burned in the cylinder during the combustion period of the engine is about 2000 ~ 2500 ℃. This heat is conducted to the cylinder walls, cylinder heads, pistons, valves and other parts. therefore. The cooling system has the function of keeping the engine temperature constant by absorbing high temperature heat so that these components do not overheat.

1 shows an air-cooled intercooler of the cooling system having the above function, and the fan 2 provided on one side of the engine 1 is used to cool the air of the intercooler 3 and is not shown in the drawing. It is also used to cool the refrigerant flowing in the radiator and condenser. In such an air-cooled intercooler system, the intercooler 3 is installed on an air inflow path supplied to the engine and receives compressed hot air from a turbo charger 4.

The hot air supplied into the intercooler 1 is cooled by cold air sucked from the outside by the fan 2 and supplied to the engine 1 to increase the combustion efficiency of the engine.

2 shows a water-cooled intercooler system, in which water, which is a refrigerant flowing in the radiator 11, is cooled by external air, and the coolant cooled refrigerant is pumped through the oil cooler 13 and the engine 14 through the pump 12. ) Is supplied to cool them. In such a water-cooled cooling system, the intercooler 15 is provided between the radiator 11 and the pump 12, and the air supplied into the intercooler 15 is cooled by the refrigerant cooled in the radiator 11 to be engine 14. By supplying the to increase the combustion efficiency of the engine.

3 shows the structure of a conventional air-cooled intercooler. The intercooler 3 includes a passage 31 through which air to be supplied to the engine flows, and a plurality of fins 32 for increasing an area in contact with the outside. Equipped with. Therefore, the air flowing to the outside and the hot air flowing to the passage 31 of the intercooler 3 exchange heat with each other to cool the air in the intercooler 3, and although not shown, in the water-cooled type, the air in the intercooler flows to the outside. The air in the intercooler was cooled by heat exchange with the refrigerant.

However, the above-described conventional intercooler has a problem that the hot air flowing through the passage of the intercooler is half-cooled by the air or the refrigerant flowing outside, and thus the cooling efficiency is not so high that the temperature cannot be lowered to a temperature sufficient to increase the combustion efficiency of the engine. There is this.

In addition, in the case of air-cooled, the intercooler is located alongside other devices such as radiators, condensors, etc., thereby impeding the flow of air sucked by the fan, which reduces the flow rate of the air, thereby lowering the cooling efficiency of the intercooler. There was a problem in that the cooling temperature is not kept constant because of the difference in the cooling temperature is severely affected by the outside temperature.

The present invention is to solve the above conventional problems. The purpose of the present invention is to provide an intercooler of a vehicle capable of increasing the output of the engine by increasing the combustion effect of the engine by increasing the cooling efficiency of the air supplied to the engine using the thermoelectric element.

Another object of the present invention is to provide an intercooler of a vehicle capable of maintaining a constant output of the engine by keeping the cooling temperature constant regardless of the influence of the outside temperature caused by the temperature difference between winter and summer.

The above object is an intercooler device of a vehicle for cooling compressed air and supplying it to an engine, wherein the at least one air passage installed to pass the compressed air is in contact with a fluid having a temperature lower than the temperature of the compressed air. And a thermoelectric element installed between the air passage and the cooling element to heat exchange between the compressed air passing through the air passage and the fluid to cool the temperature of the compressed air. It can be achieved by the intercooler device of the vehicle.

Below. The intercooler device of the vehicle according to the present invention will be described in detail with reference to the accompanying drawings. Figure 4 shows an embodiment of an air-cooled intercooler. The intercooler 40 includes a plurality of passages 41 through which air to be supplied to the engine flows, and a plurality of fins 42 are arranged between the passages 41 to increase the contact area with the outside air. It was to be able to release the heat to the outside sufficiently.

In addition, a plurality of thermoelectric elements 50 are disposed between the passage 41 and the fins 42. 5 is an enlarged view of the main portion of FIG. 4, in which the thermoelectric element 50 is provided with ceramic plates 51 and 52 on the vertical axis, and the thermoelectric material 53 is provided between the ceramic plates 51 and 52. FIG. The thermoelectric material 53 is provided, and the thermoelectric material 53 is connected to a power source.

As the thermoelectric element 50 is known, when current flows in the thermoelectric material 53, one of the upper and lower ceramic plates 51 and 52 becomes a high temperature part, and the other is a low temperature part, resulting in a temperature difference. As a result, heat exchange is performed, and the temperature of the high temperature part or the low temperature part can be set to an arbitrary temperature when the thermoelectric device is manufactured. Therefore, in the present invention, the main purpose is to cool the air, which is the fluid flowing through the passage 41 of the intercooler 40, so that the low temperature side ceramic plate 52 is in contact with the air flowing into the passage 41 of the intercooler 40. The high temperature portion side ceramic plate 51 is in contact with the pin 42 in contact with the outside air. At this time, the temperature of the low temperature portion should be set at least lower than the air temperature flowing into the furnace 41, it is possible to install a plurality of such thermoelectric elements 50 arranged in place according to the size or shape of the intercooler (40).

In the cooling system of the present invention configured as described above, when the electric power is supplied to a plurality of thermoelectric elements 50 installed in the intercooler 40, the ceramic plate 52 on one side becomes a low temperature part due to the characteristics of the thermoelectric material 53. The other ceramic plate 51 is heat exchanged by being a high temperature portion.

That is, the heat amount of the hot air flowing into the passage 41 of the intercooler 40 is absorbed by the low temperature side ceramic plate 52 of the thermoelectric element 50 and heat transferred to the high temperature side ceramic plate 51. The air flowing into the passage 41 of the intercooler 40 is cooled by being discharged to the outside through the fin 42. The heat exchange is forcibly and quickly performed by the thermoelectric element 50, thereby increasing the cooling efficiency.

The cooled air is supplied to the engine to increase the combustion efficiency to increase the output of the engine. Further, since the low temperature portion of the thermoelectric element 50 is set to a predetermined temperature, the air in the intercooler 40 can be cooled to a constant temperature regardless of the change in the outside air, that is, the difference between the outside air temperature in winter and summer.

On the other hand, Figure 6 shows a water-cooled intercooler. The intercooler 60 includes a first passage 61 through which air supplied to the engine flows, and a second passage 62 through which water as a refrigerant flows is provided between each first passage 61. The thermoelectric element 70 is provided between the first and second passages 61 and 62, so that the low-temperature-side ceramic plate 71 of the thermoelectric element 70 is disposed on the first passage 61 side of the intercooler 60. The high temperature auxiliary ceramic plate 72 is in contact with the refrigerant flowing through the second passage 62 of the intercooler 60. Accordingly, the low-temperature-side ceramic plate 71 absorbs the heat of hot air flowing through the first passage 61 of the intercooler 60, and transfers the thermoelectric material 73 to the high-temperature-side ceramic plate 72 through the intercooler 60. The air in the intercooler 60 may be cooled and supplied to the engine by being discharged to the refrigerant flowing in the second passage 62 of 60, and the heat transfer may be rapidly performed by the thermoelectric element 70, thereby cooling the intercooler. Is increased.

As described above, according to the intercooler of the vehicle according to the present invention, the thermoelectric element is installed in the intercooler and the cooling effect is superior to that of the existing intercooler, thereby increasing the combustion efficiency of the engine and increasing the output of the engine. I can downsize the intercooler as much as possible. As a result, the waterfront space of the intercooler is increased to increase the flow rate of the inflow air, thereby increasing the combustion efficiency of the engine.

In addition, the temperature of the air cooled in the intercooler by the thermoelectric element becomes constant, and in particular, it is possible to supply the engine by cooling to a constant temperature even in winter or summer when the temperature difference between the outside air is severe.
