Description

Technical Field

[0001] The utility model mainly relates to the technical field of radiators, and specifically relates to a vehicle-mounted high-low temperature integrated heat exchanger. Background Art

[0002] Traditional fuel engines only need to cool the engine, while new hybrid vehicle models need to cool both the engine and the motor at the same time. Since the cooling temperatures required by the engine and the motor are different, there are currently two solutions. One is to design a high-temperature radiator and a low-temperature radiator to cool the engine and the motor respectively. This solution will occupy more layout space due to the addition of a low-temperature radiator, and the cost pressure is also high, which is not conducive to improving the product competitiveness. The other is to integrate the high-temperature radiator and the low-temperature radiator, and a partition is arranged inside. In the existing solution, the high-temperature radiator and the low-temperature radiator are arranged side by side in a left-right manner. This will reduce the windward area of the high-temperature and low-temperature radiators and increase the wind resistance, affecting the cooling effect.

[0003] The existing radiators are a high-temperature radiator and a low-temperature radiator to cool the engine and the motor respectively. The newly added low-temperature radiator will occupy more layout space and the cost pressure is also high. Content of the Utility Model

[0004] In order to solve the deficiencies of the existing technology, the utility model provides a vehicle-mounted high-low temperature integrated heat exchanger, which is realized through the following technical solutions:

[0005] A vehicle-mounted high-low temperature integrated heat exchanger includes a water tank. A partition is fixedly installed on the upper part of the inner wall of the water tank. The partition divides the inner part of the water tank into an upper chamber and a lower chamber. An upper water inlet and a lower water inlet are respectively fixedly installed on the upper part and the lower part of one side of the water tank. The upper water inlet communicates with the upper chamber, and the lower water inlet communicates with the lower chamber. An upper water outlet and a lower water outlet are respectively fixedly installed on the upper part and the lower part of the other side of the water tank. The upper water outlet communicates with the upper chamber, and the lower water outlet communicates with the lower chamber.

[0006] Furthermore, a plurality of evenly distributed heat dissipation fins are fixedly installed on both the front and the back of the water tank.

[0007] Compared with the existing technology, the beneficial effects of the utility model are:

[0008] By arranging a partition inside the water tank, the device forms independent upper and lower chambers inside the water tank, which can enable the upper and lower chambers to be respectively applied to two sets of independent cooling systems, and can greatly reduce the volume and weight of the vehicle-mounted radiator.

[0013] Embodiment: A vehicle high and low temperature integrated heat exchanger

[0014] As Figure 1-2 shown, a vehicle high and low temperature integrated heat exchanger, its specific structure includes:

[0015] A water tank 1, the upper part of the inner wall of the water tank 1 is fixedly installed with a partition 2, the partition 2 divides the interior of the water tank 1 into an upper chamber 101 and a lower chamber 102, the upper part and the lower part of one side of the water tank 1 are respectively fixedly installed with an upper water inlet 3 and a lower water inlet 4, the upper water inlet 3 communicates with the upper chamber 101, the lower water inlet 4 communicates with the lower chamber 102, the upper part and the lower part of the other side of the water tank 1 are respectively fixedly installed with an upper water outlet 5 and a lower water outlet 6, the upper water outlet 5 communicates with the upper chamber 101, and the lower water outlet 6 communicates with the lower chamber 102.

[0016] A plurality of evenly distributed heat dissipation fins 7 are fixedly installed on the front and rear of the water tank 1.

[0017] Working principle:

[0018] When the device is in use, the upper chamber 101 and the lower chamber 102 respectively correspond to a high temperature heat dissipation system and a low temperature heat dissipation system. The cold region liquid in the upper chamber 101 and the lower chamber 102 does not interfere with each other during the circulating heat dissipation, and can respectively meet the high temperature cooling requirements of the engine and the low temperature cooling requirements of the motor. And when the device is produced, the water tank 1 can adopt an integral forming process, which can greatly improve the production efficiency, and has the advantages of good sealing structure and light overall quality.
