Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment technology, and in particular to a heat exchange module and a pure electric vehicle. Background Technology

[0002] Currently, pure electric vehicles have secured a place in the commercial vehicle sector due to their advantages of being green, pollution-free, and highly energy-efficient. Pure electric vehicles are powered by batteries, and the battery cells require suitable temperatures to operate stably. Therefore, the battery thermal management unit heats the coolant entering the battery to raise its operating temperature when the cell temperature is low, a process that consumes electricity. Simultaneously, pure electric vehicles also require electric air compressors to provide air for the braking system and related auxiliary modules. These compressors discharge high-temperature compressed air, which is then cooled and dried before being supplied to the vehicle, resulting in significant heat loss from the compressed air. Both of these factors contribute to substantial energy consumption in the vehicle.

[0003] Therefore, how to improve the energy utilization efficiency of pure electric vehicles and reduce vehicle energy consumption is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a heat exchange module to improve the energy utilization efficiency inside pure electric vehicles and reduce vehicle energy consumption.

[0005] Another objective of this invention is to provide a pure electric vehicle that includes the aforementioned heat exchange module.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat exchange module, comprising:

[0008] The heat exchange chamber has a first water inlet, a second water inlet, and a third water inlet on its side wall, which connect the inside and outside of the chamber. The first water inlet is used to introduce antifreeze into the heat exchange chamber. The second water inlet is equipped with a one-way valve, which is connected from the inside of the heat exchange chamber to the outside. The third water inlet is connected to an expansion tank.

[0009] A heat exchange tube is disposed through the heat exchange cavity. The heat exchange tube includes an air inlet and an air outlet, and the area through which the heat exchange tube passes through the heat exchange cavity is a sealed structure. The air inlet is connected to the gas outlet of the electric air compressor, and the air outlet is connected to the gas-using component.

[0010] Preferably, in the heat exchange module described above, the first water inlet and the second water inlet are located on both sides of the heat exchange cavity along its length, and the third water inlet is located between the first water inlet and the second water inlet.

[0011] Preferably, in the heat exchange module described above, the heat exchange tube in the heat exchange cavity has a spiral tubular structure.

[0012] Preferably, in the above-mentioned heat exchange module, the heat exchange cavity is a cylindrical cavity structure.

[0013] Preferably, in the heat exchange module described above, the air inlet and the air outlet are respectively disposed on two opposite circular wall surfaces of the heat exchange cavity.

[0014] Preferably, in the heat exchange module described above, a plurality of heat exchange tubes are disposed within a single heat exchange chamber, and a single gas-using component is connected to the gas outlet of one or more of the heat exchange tubes.

[0015] Preferably, in the heat exchange module described above, the first water inlet, the second water inlet, and the third water inlet have the same external structure, and the one-way valve is applicable to any of the water inlets.

[0016] Preferably, in the above heat exchange module, the heat exchange tube is a circular tube with a uniform radius, and the heat exchange tube is made of steel.

[0017] Preferably, in the above-mentioned heat exchange module, the heat exchange tube and the heat exchange cavity are welded together as an integral structure.

[0018] A pure electric vehicle is provided with a heat exchange module as described in any of the above embodiments.

[0019] As can be seen from the above technical solution, the heat exchange module provided by this utility model is equipped with a heat exchange cavity to provide heat exchange space. The heat exchange cavity is a hollow structure for containing antifreeze. It has three water inlets on the side wall, through which antifreeze is introduced through the first water inlet and discharged through the second water inlet, so as to realize the smooth circulation of antifreeze in the heat exchange cavity. The second water inlet is specially equipped with a one-way valve to prevent the antifreeze from flowing back. The third water inlet is connected to the expansion tank to effectively vent gas when there is gas in the heat exchange cavity, thereby improving the heat exchange effect of the antifreeze. Correspondingly, the heat exchange tube is set through the heat exchange cavity. The gas of the electric air compressor passes through the heat exchange tube, so as to cool the gas in the heat exchange tube through the path of the heat exchange tube and the relatively low temperature of the antifreeze, thereby providing a suitable air source for the whole vehicle. At the same time, it realizes the heating of the antifreeze, so as to heat the power battery when the cell temperature is low, thereby reducing the energy consumption of the power battery antifreeze self-heating, and thus improving the energy utilization efficiency inside the pure electric vehicle.

[0023] The core of this utility model lies in disclosing a heat exchange module to improve the energy utilization efficiency inside pure electric vehicles and reduce vehicle energy consumption.

[0024] Another key aspect of this invention is providing a pure electric vehicle that includes the aforementioned heat exchange module.

[0025] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0026] like Figure 1 As shown, the heat exchange module provided in this embodiment of the present invention mainly includes a heat exchange cavity 10 and a heat exchange tube 20. The heat exchange cavity 10 is a cavity structure with three key water inlets on its side wall: a first water inlet 110, a second water inlet 120, and a third water inlet 130. The three water inlets are spaced apart and can all connect to the inner and outer areas of the heat exchange cavity 10. Specifically, the first water inlet 110 is connected to the antifreeze filling port so that antifreeze can be added into the heat exchange cavity 10 through the first water inlet 110. The second water inlet 120 is used to allow antifreeze to flow out from the heat exchange cavity 10 and is connected to the liquid inlet of the power battery thermal management system so as to provide antifreeze to the power battery thermal management system.

[0027] Meanwhile, the second inlet 120 is specially designed with a one-way valve 30. It should be noted that the connection direction of the one-way valve 30 is from the inside of the heat exchange chamber 10 to the outside, so as to ensure that at the position of the second inlet 120, the antifreeze can only be discharged from the heat exchange chamber 10 and will not flow back in, thereby avoiding pressure buildup inside the system.

[0028] It should be further explained that the antifreeze discharged from the second water outlet 120 is received by the battery thermal management system, which is also equipped with a solenoid valve to deliver the antifreeze to the water channels around the battery cells to regulate the temperature around the battery cells.

[0029] Considering that some gas may exist in the heat exchange chamber 10, affecting the antifreeze's capacity and heat exchange, the third inlet 130 is connected to the expansion tank to allow for venting of the heat exchange chamber 10 and to allow the expansion tank to contain excess antifreeze in the heat exchange chamber 10 to maintain stable system operation.

[0030] The heat exchange tube 20 passes through the heat exchange chamber 10 and includes an air inlet 210 and an air outlet 220 extending out of the heat exchange chamber 10. The structural area through the heat exchange chamber 10 can effectively isolate the external environment and protect the internal gas from external influences. Meanwhile, the air inlet 210 of the heat exchange pipe 20 is connected to the gas outlet of the electric air compressor to receive the high-temperature compressed gas provided by the electric air compressor, while the air outlet 220 of the heat exchange pipe 20 is connected to other air-consuming components on the vehicle. On the one hand, the gas provided by the electric air compressor can be transported along the guide path of the heat exchange pipe 20 and naturally cooled. On the other hand, the antifreeze filled in the heat exchange chamber 10 can exchange heat with the high-temperature gas in the heat exchange pipe 20 to absorb the heat of the high-temperature gas and accelerate its cooling, so that the high-temperature gas can be supplied for use through a shorter path. Correspondingly, the antifreeze that exchanges heat with the high-temperature gas can absorb heat and rise in temperature. When it is necessary to heat the cells in the power battery, it can obtain a certain temperature through heat exchange with the high-temperature gas, thereby reducing the energy consumption required for heating. The above structure can integrate the working fluid that needs to dissipate heat and the working fluid that needs to be heated in the vehicle, so as to enable the energy recycling of the whole vehicle, improve the energy utilization efficiency inside the pure electric vehicle, and reduce the energy consumption of the vehicle.

[0031] Furthermore, in the above embodiment, the first inlet 110 and the second inlet 120 are the inlet and outlet of the antifreeze in the heat exchange chamber 10, respectively. To improve heat exchange efficiency and ease of operation, the first inlet 110 and the second inlet 120 are located on both sides of the length of the heat exchange chamber 10, thereby increasing the flow path of the antifreeze in the heat exchange chamber 10, increasing the time the antifreeze spends flowing through the heat exchange chamber 10, and thus increasing the heat exchange time between the antifreeze and the high-temperature gas in the heat exchange tube 20. Correspondingly, the third inlet 130 is located between the first inlet 110 and the second inlet 120, which not only saves space but also facilitates installation and maintenance.

[0032] To further optimize the above technical solution, in some embodiments of this utility model, the region of the heat exchange tube 20 located inside the heat exchange cavity 10 adopts a spiral tubular structure, which increases the length of the heat exchange tube 20 and its area within the heat exchange cavity 10, thereby improving the heat exchange efficiency. Furthermore, its compact design results in a smaller overall size of the heat exchange module, facilitating integration into various devices. The spiral tubular structure also helps reduce resistance during gas flow and improves the smoothness of gas flow, which is crucial for improving heat exchange efficiency.

[0033] Furthermore, in some embodiments of this utility model, the heat exchange cavity 10 is a cylindrical cavity structure, which has excellent symmetry and structural stability. The cylindrical design allows for full utilization of the internal space of the heat exchange cavity 10, while providing a larger heat exchange area and improving heat exchange efficiency. In addition, the cylindrical structure is easy to manufacture and process, and can adopt standardized production processes to reduce production costs. Based on the above structure, the air inlet 210 and air outlet 220 of the heat exchange tube 20 are respectively provided on two opposite circular walls of the heat exchange cavity 10, so that the heat exchange tube 20 can completely pass through the heat exchange cavity 10 in the circumferential direction, thereby increasing the heat exchange area of ​​the heat exchange tube 20 within the heat exchange cavity 10.

[0034] Furthermore, in the heat exchange module provided in this embodiment of the present invention, multiple heat exchange tubes 20 can pass through a single heat exchange chamber 10, which significantly improves the heat exchange efficiency and the heat treatment capacity of the module. Multiple heat exchange tubes 20 can operate in parallel, allowing more gas to exchange heat simultaneously, thereby improving the overall heat exchange rate. Specifically, the air inlet 210 of each heat exchange tube 20 is connected to the gas outlet of the electric air compressor. For air-consuming components of the vehicle, each air-consuming component is connected to the air outlet 220 of one or more heat exchange tubes 20, providing greater flexibility and allowing the number of heat exchange tubes 20 connected to be selected according to the air consumption of different air-consuming components, thus improving the accuracy of air consumption regulation for the air-consuming components.

[0035] Furthermore, in some embodiments of this utility model, the first port 110, the second port 120, and the third port 130 of the heat exchange module adopt the same external shape. This unified design simplifies the production and maintenance process because all ports can be manufactured using the same mold, reducing production costs. In addition, the one-way valve 30 can be applied to any port, further improving the flexibility and interchangeability of the module. This allows for easy replacement of port components when replacement or maintenance is required, without affecting the normal operation of other ports. It should also be noted that the connection positions of the interchangeable ports in the heat exchange chamber 10 can be adjusted according to actual usage needs to adapt to different installation environments.

[0036] Furthermore, in some embodiments of this utility model, the heat exchange tube 20 adopts a uniformly shaped circular tube design to ensure the strength and stability of the heat exchange tube 20 and to allow the airflow to pass through the heat exchange tube 20 uniformly. The heat exchange tube 20 is made of steel pipe, which has good thermal conductivity and corrosion resistance, enabling the heat exchange tube 20 to work stably in various environments and extending the service life of the heat exchange module. The steel pipe heat exchange tube 20 also has high mechanical strength and can withstand high working pressure, making it suitable for high-pressure gas heat exchange. It should also be noted that the heat exchange tube 20 and the heat exchange chamber 10 are welded together to form an integral structure. This design greatly enhances the overall strength and sealing of the heat exchange module. The welded connection ensures a tight fit between the heat exchange tube 20 and the heat exchange chamber 10, preventing gas leakage and improving heat exchange efficiency. In addition, the integral structure design simplifies the module assembly process, reduces the number of parts required for assembly, and lowers manufacturing costs.

[0037] Furthermore, this utility model embodiment also provides a pure electric vehicle, which integrates the heat exchange module provided in any of the above embodiments. This integrated design enables the pure electric vehicle to more effectively manage the heat generated by the battery and motor, improving vehicle performance and safety. The heat exchange module, through efficient thermal management, helps maintain the battery at its optimal operating temperature, extending battery life while reducing the risk of motor overheating. Moreover, since the heat exchange module possesses the technical effects provided in any of the above embodiments, the pure electric vehicle also possesses the technical effects provided in any of the above embodiments, which will not be elaborated upon further here.
