Description

  The present invention relates to a vehicle radiator.

  In general, automobiles travel by injecting a mixture of fuel and air into the engine cylinder and transmitting the explosive force generated by the compression of the pistons to the drive wheels. A cooling device such as a water jacket is provided for cooling, and the radiator performs the function of cooling the cooling water circulating through the water jacket again.

  A radiator having such a function is classified into an air-cooling type and a water-cooling type according to a cooling method, and is classified into a cross-flow (Down-Flow) radiator according to a configuration type.

  The cross flow and down flow radiators, which are classified according to the configuration type, are determined by the flow direction of the cooling water, and the radiator according to the prior art is arranged with the inlet and outlet tanks into which the cooling water flows in and out separated from each other. In addition, a tube that interconnects the inlet and the outlet tank is stacked and mounted so that the cooling water flows and the cooling water flowing through heat exchange with the outside air is cooled.

  Here, the crossflow type radiator is a system in which cooling water is circulated in the horizontal direction by arranging the inlet and outlet tanks on the left and right sides and mounting the tubes stacked in the horizontal direction. .

  The downflow type radiator is cooled while circulating the cooling water in the vertical direction by installing the inlet and outlet tanks vertically and connecting the tanks stacked in the vertical direction. It is a method.

  The radiator configured as described above is normally disposed forward in the engine room of the vehicle so that the cold outside air flowing in during traveling and the cooling water are heat-exchanged.

  On the other hand, recently, an intercooler that cools air compressed by a turbocharger turbine applied to improve engine output and supplies the engine to the engine is applied.

  Such an intercooler is usually classified into an air cooling type or a water cooling type, and there is a tendency that the application of the water cooling type is expanded more than the air cooling type so as to improve fuel efficiency by improving cooling performance and improving turbo lag.

  In the case of an intercooler to which the water cooling system is applied, the cooling water cooled through the radiator for the intercooler separate from the radiator that supplies the cooling water to the engine flows to cool the compressed air.

  However, such a conventional vehicle radiator is composed of an engine radiator and an intercooler radiator, and is applied in front of or behind the vehicle, so that the package increases and the installation is performed in a narrow engine room. There is a problem that space constraints occur.

  In addition, the space between the back beam and the engine room is reduced, resulting in a decrease in collision performance. The height of the radiator tubes and the radiation fins is different, and the outside air that flows in front of the vehicle passes through each radiator. At the same time, there is a problem that the ventilation resistance is excessively formed and the heat dissipation performance of the radiator is lowered.

  If the heat dissipation performance of the radiator is reduced, the cooling water cannot be cooled to the required temperature, the overall cooling efficiency is lowered, and the cooling water that is not sufficiently cooled is supplied to the engine and the intercooler. Therefore, the engine and the intercooler cannot be cooled properly, and the overall cooling performance of the vehicle is lowered.

  First, with reference to FIG. 1 thru | or FIG. 8, 1st Embodiment of this invention and its modification are demonstrated.

  As shown in the drawings, the vehicular radiator 100 according to the first embodiment of the present invention is integrally formed so as to partition the interior of each of the header tanks 110 and 120 and supply cooling water, respectively. The oil cooler 160 for cooling the transmission oil is built in, and the condenser 170 for condensing the refrigerant is built in the other one header tank, so that the vehicle package is reduced and the tubes through which each cooling water flows are the same. The heat dissipating performance can be improved by disposing on the wire to reduce the airflow resistance.

  For this purpose, the vehicle radiator 100 according to the first embodiment of the present invention is blown from outside air that is configured in front of the vehicle and flows in during traveling, and a cooling fan that is attached to the engine room (not shown). Cool the cooling water flowing inside through the wind.

  As shown in FIGS. 1 to 4, the vehicle radiator 100 includes the first header tank 110, the second header tank 120, the first and second tubes 130 and 140, the radiating fins 150, the oil cooler 160, And a capacitor 170.

  First, the first header tank 110 is partitioned into different sizes through a first partition 111 integrally formed therein so that cooling water is stored therein, so that a first chamber 113 and a second chamber 115 are formed. The

  In the first header tank 110, cooling water flows into or out of the first and second chambers 113 and 115, respectively.

  Here, the first header tank 110 is formed with a first discharge port 117 at the front lower portion of the first chamber 113 through which the cooling water flowing into the first chamber 113 is discharged.

  In addition, the first header tank 110 may have a second inlet 116 and a second outlet 118 through which cooling water flows in and out of the upper and lower portions of the second chamber 115 in the width direction of the radiator.

  The first chamber 113 may have a width (W1) greater than the width (W2) of the second chamber 115 with respect to the thickness direction of the radiator (W1).

  In the first embodiment, the second header tank 120 is spaced apart from the first header tank 110 by a certain distance, and the second partition 121 is integrally formed inside corresponding to the first partition 111. The third and fourth chambers 123 and 125 are formed in different sizes.

  The second header tank 120 discharges cooling water flowing into the third chamber 123 to the first chamber 113 of the first header tank 110 and cools into the second chamber 115 of the first header tank 110. After allowing water to flow into the fourth chamber 125, the cooling water is again discharged from the fourth chamber 125 to the second chamber 115.

  Here, the second header tank 120 may have a first inflow port 127 through which cooling water flows into the third chamber 123 at an upper front portion of the third chamber 123.

  Further, the fourth chamber 125 may be formed with a width (W4 <W4) that is greater than the width (W4) of the third chamber 123 with respect to the thickness direction of the radiator.

  That is, in the first and second header tanks 110 and 120, the second chamber 115 and the third chamber 123 are formed with the same width (W2 = W3) with respect to the thickness direction of the radiator. The chamber 113 and the fourth chamber 125 may be formed with the same width (W1 = W4) with respect to the thickness direction of the radiator.

  In the first header tank 110 and the second header tank 120 configured as described above, the first chamber 113 and the third chamber 123 are disposed toward the front of the vehicle, and the second chamber 115 and the fourth chamber 125 are disposed. Can be arranged towards the rear of the vehicle.

  Meanwhile, in the first embodiment, the first header tank 110 divides the second chamber 115 in the height direction between the second inflow port 116 and the second discharge port 118. A diaphragm 119 may be integrally formed to prevent the cooling water flowing into the first chamber from being mixed with the cooling water flowing from the fourth chamber 125 into the second chamber 115.

  As a result, the cooling water flowing into the second inlet 116 is prevented from being immediately discharged to the second outlet 118 by the diaphragm 119.

  In the first embodiment, the first tube 130 interconnects the first chamber 113 of the first header tank 110 and the third chamber 123 of the second header tank 120.

  The second tube 140 interconnects the second chamber 115 of the first header tank 110 and the fourth chamber 125 of the second header tank 120.

  A plurality of the first tubes 130 and the second tubes 140 are mounted along the height direction at positions separated from the inner surfaces of the first and second header tanks 110 and 120, respectively.

  Here, the first and second tubes 130 and 140 may be mounted at regular intervals along the height direction of the first header tank 110 and the second header tank 120.

  In addition, the first tube 130 may have a width of about 14 mm, and the second tube 140 may have a width of about 18 mm.

  Accordingly, the cooling water passing through the second tube 140 flows at a flow rate higher than the flow rate of the cooling water flowing through the first tube 130.

  On the other hand, in the first embodiment, the width of the second tube 140 is formed longer than the width of the first tube 130 and the flow rate of the cooling water is different and flows. However, the present invention is not limited to this, and the length of each of the tubes 130 and 140 can be changed and applied according to the amount of heat radiation required by the engine and the intercooler. It is.

  Here, the first and third tubes 130 and 140 correspond to the first and third chambers 113 and 123 corresponding to each other along the height direction of the first header tank 110 and the second header tank 120. And the second and fourth chambers 115 and 125 may be disposed on the same line.

  Meanwhile, in the first embodiment, the cooling water flowing into the second chamber 115 through the second inlet 116 flows to the fourth chamber 125 through the second tubes 140 at the upper part with respect to the diaphragm 119, In the lower part, the fluid flows from the fourth chamber 125 to the second chamber 115 through the second tube 140.

  As shown in FIG. 5, the heat radiating fins 150 are respectively formed between the plurality of first tubes 130 and the plurality of second tubes 140 and flow through the first and second tubes 130 and 140. The heat transferred from the cooling water is released to the outside.

  Here, the radiating fins 150 may be disposed at the same bent positions between the first tubes 130 and the second tubes 140.

  The radiating fins 150 are separated from the first tubes 130 and the second tubes 140 in a state of being separated from the first tubes 130 and the second tubes 140 separated in the thickness direction of the radiator. Each can be installed separately.

  That is, in the first embodiment, the plurality of first and second tubes 130 and 140 are disposed between the first header tank 110 and the second header tank 120 by the respective chambers 113, 115, 123, and 125. It arrange | positions on the same line in the height direction of a vehicle in the position respectively spaced apart in the thickness direction.

  The radiating fins 150 are disposed at the same bent position between the plurality of first tubes 130 and the plurality of second tubes 140.

  As a result, when the outside air that flows in flows through the radiator 100 while the vehicle is running, the ventilation resistance of the outside air decreases and the radiator 100 flows more smoothly. Therefore, the radiator 100 can improve the overall heat dissipation performance and increase the cooling efficiency of the cooling water.

  In the first embodiment, the oil cooler 160 is provided in the first chamber 113 disposed in the first header tank 110 toward the front of the vehicle.

  The oil cooler 160 is connected to an automatic transmission (not shown) through an oil pipe 161 inside the first chamber 113 having a large width (W1), and transmission oil circulates in the first chamber 113. Transmission oil is cooled through heat exchange with cooling water passing through 113.

  The transmission oil cooled through the oil cooler 160 is supplied to an automatic transmission (not shown) to complete cooling of the automatic transmission, and then circulates by flowing into the oil cooler 160 again.

  The capacitor 170 is provided in the fourth chamber 125 disposed toward the rear of the vehicle in the second header tank 120.

  The condenser 170 is provided in the fourth chamber 125 having a large width (W4), and a refrigerant supplied from a compressor (not shown) circulates through the refrigerant pipe 171 and passes through the fourth chamber 125. The refrigerant is condensed through heat exchange with the cooling water.

  Here, the condenser 170 flows through the second chamber 115 and passes through the second tube 140 while being heat exchanged with the outside air, and passes through the cooled cooling water flowing into the fourth chamber 125. Heat exchange with refrigerant circulating in

  The refrigerant cooled and condensed through the condenser 170 is supplied to the evaporator, and is circulated by flowing into the condenser 170 again from the evaporator through the compressor.

  Here, the plurality of second tubes 140 connecting the second chamber 115 and the fourth chamber 125 are formed to be longer than the plurality of first tubes 130, so that the flowing cooling water flows. As the flow rate increases, the cooling efficiency of the capacitor 170 built in the fourth chamber 125 can be improved.

  On the other hand, since the oil cooler 160 can satisfy the heat exchange efficiency even with a smaller coolant flow rate than the condenser 170, the transmission oil can be efficiently cooled.

  In the thus configured radiator 100, the cooling water cooled through heat exchange with the outside air while passing through the first tubes 130 between the first chamber 113 and the third chamber 123 is not shown. Circulate to locomotive engine or eco-friendly car driving parts.

  Then, the cooling water cooled through heat exchange with the outside air while passing through each second tube 140 between the second chamber 115 and the fourth chamber 125 enters an intercooler or environment of an internal combustion engine vehicle (not shown). It circulates in the electric power parts of easy cars.

  That is, the vehicle radiator 100 according to the first embodiment of the present invention can be configured to supply cooling water to an engine and an intercooler in an internal combustion engine vehicle, while driving components in an environment-friendly vehicle such as an electric vehicle and a hybrid vehicle. Since it can be configured to supply cooling water to the electrical components, it can be applied to all vehicles of internal combustion engines and vehicles that are environmentally friendly.

  Hereinafter, the operation and action of the vehicle radiator 100 according to the first embodiment of the present invention will be described.

Through the third chamber 123.

  The cooling water is cooled through heat exchange with the outside air while flowing from the third chamber 123 to the first chamber 113 along the plurality of first tubes 130, and the first chamber of the first header tank 110 is cooled. The fuel is again supplied to the engine of the internal combustion engine or the driving parts of the environment-friendly vehicle through the second exhaust port 117 formed at the lower part of the 113.

  At this time, the cooled cooling water flowing into the first chamber 113 is subjected to mutual heat exchange with transmission oil passing through the oil cooler 160 provided in the first chamber 113 while the transmission is being transmitted. Allow oil to cool.

  Then, the cooling water that has cooled the electrical components of the intercooler or the environment-friendly vehicle flows into the second inlet 116 formed at the upper part of the second chamber 115 of the first header tank 110 as shown in FIG. To do.

  The cooling water flowing into the second inlet 116 is primarily cooled through heat exchange with the outside air along the plurality of second tubes 140 up to the diaphragm 119 in the upper part of the second chamber 115. It flows into the four chambers 125.

  The cooling water flowing into the fourth chamber 125 condenses the refrigerant while mutual heat exchange with the refrigerant passing through the condenser 170 provided in the fourth chamber 125.

  Thereafter, the cooling water flows from the fourth chamber 125 to the second chamber 115 along the plurality of second tubes 140 positioned below with respect to the diaphragm 119 of the second chamber 115, and then heats with outside air. Secondary cooling through exchange.

  Cooling water that has been cooled into the second chamber 115 is discharged through a second discharge port 118 located below the second chamber 115 and supplied again to an intercooler or an environmentally friendly vehicle electrical component. .

  In other words, each cooling water that cools the engine and the intercooler or the environmentally friendly driving parts and electrical components of the vehicle is cooled through heat exchange with the outside air while repeatedly performing the above-described operation.

  Here, the plurality of first and second tubes 130 and 140 are arranged on the same line, and the positions where the heat radiation fins 150 located between the tubes 130 and 140 are bent are arranged in the same manner. The ventilation resistance is reduced, and the outside air flows into the radiator 100 more smoothly.

  As a result, the radiator 100 is improved in heat dissipation performance due to smooth inflow of outside air due to reduction of the outside air ventilation resistance.

  Accordingly, when the vehicle radiator 100 according to the first embodiment of the present invention configured as described above is applied, the interiors of the first and second header tanks 110 and 120 are partitioned into different sizes from each other. The intercooler is integrally configured to supply cooling water to each of the intercoolers, and an oil cooler for cooling transmission oil is built in the first chamber 113 of the first header tank 110, and the fourth header tank 120 has a fourth By incorporating a condenser for condensing the refrigerant in the chamber 125, the vehicle package can be reduced, and the weight and size can be reduced.

  In addition, the radiator 100 can improve the space utilization inside the engine room by reducing the package, and can secure a sufficient space between the back beam and the engine room to improve the collision performance.

  In addition, the plurality of first tubes 130 and the plurality of second tubes 140 are disposed on the same line in the thickness direction of the radiator while interconnecting the respective chambers 113, 115, 123, 125. When the outside air flows in, the ventilation resistance can be reduced to improve the overall heat dissipation performance.

  Further, by cooling the cooling water to the required temperature through improving the heat dissipation performance of the radiator 100, the cooling performance of the engine and the intercooler can be improved without increasing the size and capacity.

  The cooling efficiency of the refrigerant and the transmission oil can be improved by incorporating the oil cooler 160 and the condenser 170 in the header tank so as to be water-cooled.

  Meanwhile, a vehicle radiator 200 according to a modification of the first embodiment of the present invention will be described with reference to FIG.
