As shown, the cooling module for a fuel cell vehicle according to the first embodiment of the present invention may be largely composed of a first stack radiator 100, a second stack radiator 200, and an electric radiator 300.

The first stack radiator 100 is connected to the fuel cell stack of the fuel cell vehicle to cool the cooling water that cools the fuel cell stack while passing through the inside of the first stack radiator 100. In addition, the first stack radiator 100 may be composed of a plurality of tubes and a core portion 110 coupled with a fin interposed between the tubes and a pair of header tanks 120 connected to both ends of the tubes, and a header tank In the 120s, an inlet 130 through which the cooling water is introduced and an outlet 140 through which the cooling water is discharged may be formed. Here, the first stack radiator 100 may be disposed so that the header tanks 120 are positioned at the upper and lower sides in the height direction, and the inlet 130 through which cooling water flows into the header tank 120 disposed at the upper side in the height direction is provided. A discharge port 140 through which the cooling water is discharged may be formed in the header tank 120 disposed at the lower side in the height direction. Thus, the coolant introduced through the inlet 130 passes through the upper header tank 120, is distributed to the tubes, passes through the tubes, and then merges at the lower header tank 120 and discharged through the outlet 140. have. That is, the first stack radiator 100 may be formed in a down flow method in which the coolant passing through the tubes of the core portion 110 flows in the height direction.

The second stack radiator 200 may be cooled while passing through the inside of the second stack radiator 200 by being connected to the fuel cell stack of the fuel cell vehicle like the above-described first stack radiator and cooling the fuel cell stack. . At this time, the second stack radiator 200 is connected in parallel to the fuel cell stack together with the first stack radiator 100 to allow the coolant to flow. In addition, the second stack radiator 200 may be composed of a plurality of tubes and a core portion 210 coupled with a fin interposed between the tubes and a pair of header tanks 220 connected to both ends of the tubes, and a header tank In the 220, an inlet 230 through which cooling water is introduced and an outlet 240 through which the cooling water is discharged may be formed. Here, in the second stack radiator 200, the header tanks 220 may be formed on both sides in the longitudinal direction, and an inlet 230 through which cooling water flows into the header tank 220 disposed at one side in the longitudinal direction is formed, and the longitudinal direction A discharge port 240 through which cooling water is discharged may be formed in the header tank 220 disposed on the other side. Thus, the coolant introduced through the inlet 230 passes through the header tank 220 on one side, is distributed to the tubes, passes through the tubes, and then merges at the other header tank 220 and discharged through the outlet 240. . That is, the second stack radiator 200 may be formed in a cross flow method in which the coolant passing through the tubes of the core part 210 flows in the longitudinal direction. Alternatively, although not shown, the second stack radiator 200 is formed in a U-flow method in which the cooling water passing through the tubes of the core part 210 flows in the longitudinal direction, but the inflow and discharge of the cooling water are performed at one side in the longitudinal direction. It could be. In addition, the second stack radiator 200 may be disposed in front of the first stack radiator 100 in the width direction, which is the flow direction of the cooling air, and the second stack radiator 200 is perpendicular to the flow direction of the cooling air. It may be disposed to overlap the first stack radiator 100 in a height direction and a length direction, which are directions. Thus, the cooling air may be configured to pass first through the second stack radiator 200 and then through the first stack radiator 100.

The electric radiator 300 is connected to electric parts such as a driving motor and an inverter of a fuel cell vehicle, so that the coolant for cooling the electric parts may be cooled while passing through the inside of the electric radiator 300. In addition, the electric radiator 300 may be composed of a plurality of tubes and a core portion 310 coupled with a fin interposed between the tubes and a pair of header tanks 320 connected to both ends of the tubes, and a header tank 320 ) May be formed with an inlet 330 through which the cooling water is introduced and an outlet 340 through which the cooling water is discharged. Here, in the full-length radiator 300, the header tanks 320 may be formed on both sides in the longitudinal direction, and an inlet 330 through which coolant flows into the header tank 320 disposed on one side in the longitudinal direction is formed, and is formed on the other side in the longitudinal direction A discharge port 340 through which cooling water is discharged may be formed in the disposed header tank 320. Thus, the coolant introduced through the inlet 330 passes through the header tank 320 on one side, is distributed to the tubes, passes through the tubes, and then merges at the other header tank 320 and discharged through the outlet 340. . That is, the full-length radiator 300 may be formed in a cross flow method in which coolant passing through the tubes of the core part 310 flows in the longitudinal direction like the second stack radiator 200.

It may be disposed to overlap with the stack radiator 100. In addition, the full-length radiator 300 is disposed under the second stack radiator 200 in the height direction so that the second stack radiator 200 and the full-length radiator 300 overlap each other in a direction perpendicular to the flow direction of the cooling air. It can be arranged not to be. Thus, the cooling air may be configured to first pass through the full-length radiator 300 separately from the second stack radiator 200 and then pass through the first stack radiator 100.

Here, the second stack radiator 200 is disposed in the upper area in the height direction, which is the side where the coolant of the first stack radiator 100 is introduced, and lower in the height direction, which is the side where the coolant of the first stack radiator 100 is discharged. An electric radiator 300 is disposed in the side area. At this time, the cooling water flowing into the first stack radiator 100 and the second stack radiator 200 is both about 80 degrees Celsius, and the cooling water flowing into the full-length radiator 300 is about 60 degrees Celsius. Therefore, the cooling air flowing into the second stack radiator 200 may cool the second stack radiator 200 and then cool the upper side of the first stack radiator 100. In addition, after cooling air introduced toward the electric radiator 300 cools the electric radiator 300, the lower side of the first stack radiator 100 may be cooled. That is, the cooling water that passes through the second stack radiator 200 and passes through the upper side of the first stack radiator 100 by relatively high-temperature cooling air whose temperature has risen, and passes through the full-length radiator 300 And it passes through the lower side of the first stack radiator 100 by the relatively low-temperature cooling air with an increased temperature, and may be further cooled, thereby improving heat exchange efficiency of the stack radiators.

In addition, the header tanks 120 of the first stack radiator 100 may be disposed outside the second stack radiator 200 and the full-length radiator 300 in the height direction. That is, the upper header tank 120 of the first stack radiator 100 is disposed above the upper end of the core part 210 of the second stack radiator 200, and the lower header tank of the first stack radiator 100 The 120 may be disposed below the lower end of the core portion 310 of the electric radiator 300. Thus, the header tanks 120 of the first stack radiator 100 do not block the flow of cooling air passing through the core part 210 of the second stack radiator 200 and the core part 310 of the electric radiator 300. Heat exchange efficiency can be improved.

Similarly, the header tanks 220 of the second stack radiator 200 and the header tanks 320 of the full-length radiator 300 may be disposed outside the first stack radiator 100 in the longitudinal direction. That is, the header tank 220 in the longitudinal direction to the left of the second stack radiator 200 is disposed further to the left than the left end of the core portion 110 of the first stack radiator 100, and the second stack radiator 200 The header tank 220 on the other side in the longitudinal direction on the right side of the first stack radiator 100 may be disposed on the right side more than the right end of the core portion 110. Thus, the header tanks 220 of the second stack radiator 200 and the header tanks 320 of the full-length radiator 300 prevent the flow of cooling air passing through the core portion 110 of the first stack radiator 100. It is not possible to improve the heat exchange efficiency. Here, it is shown that the header tanks 220 of the second stack radiator 200 and the header tanks 320 of the full-length radiator 300 are all disposed outside the first stack radiator 100 in the longitudinal direction, but the header Only some or a portion of the tanks 220 and 320 may be disposed outside.

After that, cooling air of a relatively high temperature may cool the upper side of the first stack radiator 100. In addition, the cooling air flowing into the electric radiator 300 cools the electric radiator 300, and then the cooling air of a relatively low temperature passes through the lower side of the first stack radiator 100 and passes through the first stack radiator 100. The cooling water passing through can be further cooled. Thus, it is possible to improve the heat exchange efficiency of the stack radiators.
