Description

Technical Field

[0001] The present invention belongs to the technical field of new energy thermal management, and in particular relates to a thermal management integrated module and a vehicle having the same. Background Art

[0002] As new energy vehicles develop faster and faster, the design of their thermal management systems has become increasingly important. The thermal management system is an important component of new energy vehicles, and the thermal management integrated module is the core of the thermal management system, which adjusts the heat exchange temperature by controlling the flow of refrigerant and antifreeze. The existing thermal management integrated module chooses to physically isolate the high and low pressure flow channels of the refrigerant externally to achieve the purpose of reducing heat loss. Due to the large temperature difference between each section in the refrigerant circuit and the large temperature difference between the refrigerant and the environment, more heat loss occurs, and the heat in the system circuit is not effectively utilized.

[0003] Therefore, it is necessary to invent a thermal management integrated module that can efficiently exchange heat and is integrated. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies of the above-mentioned background technology and to provide a thermal management integrated module and a vehicle having the same.

[0005] The technical solution adopted by the present invention is: a thermal management integrated module, including a water-cooled condenser and a liquid storage tank integrated on a refrigerant flow channel plate, the refrigerant flow channel plate also integrating a built-in heat exchanger, the built-in heat exchanger is provided with a high-temperature and high-pressure refrigerant inlet and a high-temperature and high-pressure refrigerant outlet and a low-temperature and low-pressure refrigerant inlet and a low-temperature and low-pressure refrigerant outlet, the high-temperature and high-pressure refrigerant inlet and the high-temperature and high-pressure refrigerant outlet are connected through a first flow channel located inside the built-in heat exchanger, the low-temperature and low-pressure refrigerant inlet and the low-temperature and low-pressure refrigerant outlet are connected through a second flow channel located inside the built-in heat exchanger, and the first flow channel and the second flow channel are independent of each other.

[0006] A further preferred structure is that the refrigerant outlet of the water-cooled condenser is connected to the inlet of the liquid storage tank, the outlet of the liquid storage tank is connected to the high-temperature and high-pressure refrigerant inlet of the built-in heat exchanger, the high-temperature and high-pressure refrigerant outlet on the built-in heat exchanger is connected to the external air-conditioning evaporator and the inlet of the water-cooled evaporator, the external air-conditioning evaporator and the water-cooled evaporator outlets are connected to the low-temperature and low-pressure refrigerant inlet, the low-temperature and low-pressure refrigerant outlet is connected to the inlet of the air-conditioning compressor, and the refrigerant inlet of the water-cooled condenser is connected to the outlet of the air-conditioning compressor.

[0007] A further preferred structure is that the built-in heat exchanger is provided with two or more partitions, the partition wall surface is corrugated, and the partition wall surface is used for heat exchange between high-temperature and high-pressure refrigerant and low-temperature and low-pressure refrigerant; the partitions form a long strip annular structure connected end to end, and the space inside the long strip annular structure constitutes the first flow channel, and the remaining space inside the built-in heat exchanger outside the long strip annular structure surrounded by the partitions constitutes the second flow channel.

[0008] In a further preferred structure, the high-temperature and high-pressure refrigerant and the low-temperature and low-pressure refrigerant flow in opposite directions in the first flow channel and the second flow channel.

[0009] In a further preferred structure, the partition includes two, and the two partitions form two long strip-shaped annular structures, and the radial center lines of the two partitions are parallel to each other.

[0010] In a further preferred structure, the adjacent partitions are arranged to form two long ring structures at intervals.

[0011] The invention also discloses a vehicle, comprising the thermal management integrated module.

[0012] The built-in heat exchanger of the present invention is built into the thermal management integrated module, and a turbulent structure (corrugated partition) is designed on the heat exchange wall to improve the heat transfer coefficient between the high-temperature and high-pressure side and the low-temperature and low-pressure side of the thermal system; the heat exchange area on the high- and low-pressure sides can be increased according to the need for heat exchange, that is, the number of the first flow channel and the second flow channel structure, which has high scalability.

[0013] The turbulent flow structure design of the corrugated partition of the present invention improves the heat exchange efficiency: the turbulent flow can destroy the fluid boundary layer and fully mix the various parts of the fluid, thereby improving the heat exchange efficiency.

[0014] The turbulent flow structure design of the corrugated partition of the present invention reduces the thermal resistance between the fluid and the wall surface, making the heat transfer more efficient.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.

[0021] Embodiment 1:

[0022] like Figure 1-4 As shown, a thermal management integrated module of the present invention includes a water-cooled condenser 1 and a liquid storage tank 2 integrated on a refrigerant flow channel plate. A built-in heat exchanger 3 is also integrated on the refrigerant flow channel plate. A high-temperature and high-pressure refrigerant inlet H1 and a high-temperature and high-pressure refrigerant outlet H2 as well as a low-temperature and low-pressure refrigerant inlet L1 and a low-temperature and low-pressure refrigerant outlet L2 are provided on the built-in heat exchanger 3. The high-temperature and high-pressure refrigerant inlet H1 is connected to the high-temperature and high-pressure refrigerant outlet H2 through a first flow channel 10 located inside the built-in heat exchanger 3, and the low-temperature and low-pressure refrigerant inlet L1 is connected to the low-temperature and low-pressure refrigerant outlet L2 through a second flow channel 20 located inside the built-in heat exchanger 3. The first flow channel 10 and the second flow channel 20 are independent of each other.

[0023] The refrigerant outlet of the water-cooled condenser 1 is connected to the inlet of the liquid storage tank 2, the outlet of the liquid storage tank 2 is connected to the high-temperature and high-pressure refrigerant inlet H1 on the built-in heat exchanger 3, the high-temperature and high-pressure refrigerant outlet H2 on the built-in heat exchanger 3 is connected to the external air-conditioning evaporator and the inlet of the water-cooled evaporator, the external air-conditioning evaporator and the water-cooled evaporator outlets are connected to the low-temperature and low-pressure refrigerant inlet L1, the low-temperature and low-pressure refrigerant outlet L2 is connected to the inlet of the air-conditioning compressor, and the refrigerant inlet of the water-cooled condenser 1 is connected to the outlet of the air-conditioning compressor.

[0024] In some optional embodiments, two or more partitions are provided in the built-in heat exchanger 3, and the partition wall surface is corrugated, and the partition wall surface is used for heat exchange between high-temperature and high-pressure refrigerant and low-temperature and low-pressure refrigerant; the partitions form a long strip ring structure connected end to end, and the space inside the long strip ring structure constitutes a first flow channel 10, and the remaining space inside the built-in heat exchanger 3 outside the long strip ring structure surrounded by the partition constitutes a second flow channel 20.

[0025] In some optional embodiments, the high-temperature and high-pressure refrigerant and the low-temperature and low-pressure refrigerant flow in opposite directions in the first flow channel 10 and the second flow channel 20 .

[0026] In this embodiment, there are two partitions, which form two long ring structures to form two first flow channels 101 and 102. The radial center lines of the first flow channels 101 and 102 are parallel to each other. The second flow channels 201, 202 and 203 are outside the first flow channels 101 and 102.

[0027] like Figure 1As shown, the water-cooled condenser 1 also exchanges antifreeze with the kettle 4. A water valve 5 and a water pump 6 are provided between the water-cooled condenser 1 and the kettle 4. The kettle 4, the water valve 5 and the water pump 6 are all integrated on the refrigerant flow channel plate.

[0028] During operation, high-temperature and high-pressure refrigerant enters the internal heat exchanger 3 from the inlet H1, enters the internal first flow channels 101 and 102 through the diversion structure, and gathers at the outlet H2; low-temperature and low-pressure refrigerant enters the second flow channels 201, 202, and 203 from the inlet L1, and flows out after merging at the outlet L2.

[0029] The media on both sides exchange heat through the built-in corrugated partition wall, which strengthens the turbulence of the medium in the flow channel; in addition, the flow directions of the media on both sides are opposite, further improving the heat exchange effect on both sides.

[0030] If it is necessary to further improve the heat exchange capacity of the built-in heat exchanger 3, it can be achieved by increasing the number of internal flow channels or adjusting the density of the turbulent structure.
