Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
[0036] In the prior art, the heat exchange module of a vehicle is installed in the front engine compartment of the vehicle. Usually, multiple heat exchangers in the heat exchange module are independently arranged and installed, and then the multiple heat exchangers are connected through external pipelines and further connected to a compressor to form a refrigerant cycle. This makes the heat exchange module require multiple connecting pipelines to be arranged, further increasing the complexity of the pipeline distribution in the front engine compartment. Moreover, for different refrigerants, since compressors and heat exchangers of different specifications and models are required, the compressor and the heat exchange module need to be replaced together. And the steps required for disassembling and assembling multiple independently arranged heat exchangers are numerous, which is not conducive to the replacement of the refrigerant.
[0037] The present utility model provides a heat exchange module.
[0038] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the heat exchange module is applied to a vehicle, and the heat exchange module includes:
[0039] A flow channel plate 100, in which a refrigerant flow channel 110 is provided. Connection ports communicating with the refrigerant flow channel 110 are provided on opposite sides of the flow channel plate 100 in the thickness direction.
[0040] A liquid storage dryer 204, a heat exchanger, and a throttling element 300 are arranged on both sides of the flow channel plate 100 in the thickness direction. The liquid storage dryer 204, the heat exchanger, and the throttling element 300 are communicated with the connection ports to form a refrigerant circuit with a compressor.
[0041] The technical solution of the present utility model arranges the liquid storage dryer, the heat exchanger, and the throttling element 300 on both sides of the flow channel plate 100 in the thickness direction. That is, both sides of the flow channel plate 100 distributed in the thickness direction can be used for installing the heat exchanger, the throttling element 300, and the liquid storage dryer 204. In this way, the length of the refrigerant flow channel 110 in the flow channel plate 100 can be shortened, the volume of the flow channel plate 100 can be reduced. At the same time, it also avoids arranging pipelines for connecting the heat exchanger, the liquid storage dryer 204, and the throttling element 300 outside the heat exchange module, making the pipeline layout in the front engine compartment relatively simple and improving the compactness of the heat exchange module, thereby improving the space utilization rate of the front engine compartment. In addition, the refrigerant is transmitted between the liquid storage dryer 204, the heat exchanger, and the throttling element 300 through the refrigerant flow channel 110 of the flow channel plate 100. By adjusting the positions of the connection ports provided on the refrigerant flow channel 110 of the flow channel plate 100, the positions of the liquid storage dryer 204, the heat exchanger, and the throttling element 300 can be flexibly adjusted, so as to adapt to different front engine compartment space requirements and different vehicle models, thereby improving the applicability of the heat exchange module.
[0042] It should be noted that multiple refrigerant channels 110 are formed in the flow channel plate 100, and the refrigerant circuit means that at least one of the heat exchanger, the liquid receiver dryer 204, and the throttling element is connected to the compressor through the refrigerant channels 110 of the flow channel plate 100. It can be that the throttling element forms a refrigerant cycle with the compressor through the refrigerant channels 110; it can also be that the heat exchanger, the liquid receiver dryer 204, the throttling element, and the heat exchanger are connected through the refrigerant channels 110, and then form another refrigerant cycle with the compressor. For example: first, the heat exchanger is connected to the liquid receiver dryer 204 through a refrigerant channel 110, the liquid receiver dryer 204 is then connected to the throttling element 300 through another refrigerant channel 110, the throttling element 300 is connected to another heat exchanger through yet another refrigerant channel 110, and then connected to the compressor to form a refrigerant circuit. It can be understood that multiple heat exchangers are provided, and multiple heat exchangers and the throttling element 300 are arranged on the same extended plane of the flow channel plate 100 or on two extended planes opposite to each other in the thickness direction. Specifically, for the liquid receiver dryer 204, the heat exchanger, and the throttling element 300 arranged on both sides in the thickness direction of the flow channel plate 100, it can be understood that: the liquid receiver dryer 204 is independently arranged on one side of the flow channel plate 100 in the thickness direction, and the heat exchanger and the throttling element 300 are arranged together on the other side of the flow channel plate 100 in the thickness direction; it can also be understood that: the liquid receiver dryer 204 and the throttling element 300 are arranged together on one side of the flow channel plate 100 in the thickness direction, and the heat exchanger is arranged on the other side of the flow channel plate 100 in the thickness direction; it can also be understood that: a part of the multiple heat exchangers and the liquid receiver dryer 204 are arranged together on one side of the flow channel plate 100 in the thickness direction, and another part of the heat exchangers and the throttling element 300 are arranged on the other side of the flow channel plate 100 in the thickness direction.
[0043] Here, the flow channel plate 100 is plate-shaped, and the thickness direction is the direction where the thickness of its shape is located. Similarly, as Figure 1 shown, the Y direction referred to in this embodiment represents the vehicle width direction, the X direction represents the vehicle length direction, and the Z direction represents the vehicle height direction. In the embodiments of the present invention, there are directional indications involved, such as up, down, front, back, left, right, etc., all with reference to the normal use state of the vehicle. If this specific posture changes, then the directional indications will also change accordingly.
[0044] Among them, since different refrigerants require different specifications and models of compressors and heat exchangers, that is, different refrigerants are adapted to different heat exchange modules. For the highly integrated heat exchange module of this embodiment, when replacing different refrigerants, the heat exchange module can be integrally disassembled and assembled on the vehicle frame, thereby improving the operation convenience of replacing refrigerants. Without loss of generality, when the heat exchange module is installed on the vehicle frame, a shock absorption assembly can be arranged on the lower side of the flow channel plate 100 for installation on the vehicle frame, reducing the complexity and installation difficulty of the shock absorption assembly.
[0045] In one embodiment, please refer to Figure 1 and Figure 3 , the heat exchange module includes a plurality of heat exchangers, and the plurality of heat exchangers are configured as a condenser 201, a subcooler 202, and an evaporator 203. The condenser 201, the subcooler 202, and the evaporator 203 are sequentially distributed from bottom to top. It should be noted that the condenser 201 has a relatively large volume, and the extending direction of the flow channel plate 100 is parallel to the vertical direction. Setting the condenser 201 at the lower part is beneficial to ensuring the stability of the heat exchange module. At the same time, the circulation sequence of the refrigerant in the heat exchange module is as follows: condenser 201, liquid storage dryer 204, subcooler 202, throttling element 300, evaporator 203. By sequentially distributing the condenser 201, the subcooler 202, and the evaporator 203 from bottom to top, the refrigerant flow channel 110 connecting the condenser 201 to the subcooler 202 is shortened. Then, by setting the evaporator 203 at the upper part, the refrigerant flow channel 110 connecting the subcooler 202 to the evaporator 203 can be shortened, thereby reducing the volume of the flow channel plate 100 and improving the compactness of the heat exchange module. In addition, from the condenser 201 to the evaporator 203, the temperature of the refrigerant gradually decreases. The above distribution method can form a natural heat transfer gradient from bottom to top, and then form a cold and hot partition on the flow channel plate 100, which helps to optimize the heat exchange process between the refrigerant and the coolant and improve the thermal efficiency of the heat exchange module. Of course, in other embodiments, the condenser 201 can also be set at the upper part of the flow channel plate 100, the evaporator 203 can be set at the lower part of the flow channel plate 100, and the subcooler 202 can be set between the condenser 201 and the evaporator 203.
[0046] Furthermore, in this embodiment, please refer to Figures 1 to 3 , the refrigerant flow channel 110 includes a main circulation flow channel 140, the throttling element 300 includes an expansion valve 301, the expansion valve 301 and the subcooler 202 are arranged in parallel between the condenser 201 and the evaporator 203, and the main circulation flow channel 140 is sequentially connected to the condenser 201, the subcooler 202, the expansion valve 301, and the evaporator 203. It can be understood that after the main circulation flow channel 140 is connected to the above components, it is then connected to the compressor to form a main circulation loop, that is, the refrigerant loop includes the main circulation loop. The expansion valve 301 is located between the evaporator 203 and the condenser 201 in the vertical direction. Similarly, in the main circulation loop, the expansion valve 301 is also located between the condenser 201 and the evaporator 203. In this way, the length of the refrigerant flow channel 110 connecting the evaporator 203 and the condenser 201 can be shortened, and the compactness of the heat exchange module can be improved. Of course, in other embodiments, the expansion valve 301 can also be arranged in parallel with the evaporator 203 or the condenser 201 in the horizontal direction.
[0047] In one embodiment, please refer to Figure 1 and Figure 2, the flow channel plate 100 is further provided with a heat exchange flow channel 120. The heat exchange flow channel 120 is provided with a heat exchange interface 121 on the side of the flow channel plate 100. The heat exchange flow channel 120 communicates with the heat exchanger, and the heat exchange interface 121 is used to be connected to the air outlet module of the vehicle's air conditioner through a pipeline. It can be understood that the heat exchange flow channel 120 and the refrigerant flow channel 110 are arranged in the flow channel plate 100. The refrigerant flow channel 110 allows the refrigerant to flow to form a refrigerant circuit with the compressor. The heat exchange flow channel 120 also allows the refrigerant to flow. After heat exchange with the coolant in the condenser 201 or the subcooler 202, the low-temperature refrigerant can be transferred to the air outlet module of the air conditioner through a pipeline to meet the cold quantity requirement for the air conditioner to deliver cold air. Or it can be directly connected to the compressor from the heat exchange flow channel 120, and the high-temperature refrigerant can be directly transported to the air outlet module of the air conditioner from the heat exchange interface through a pipeline to meet the heat requirement for the air conditioner to deliver warm air. Or pipelines connected to the compressor or the condenser 201 and the subcooler 202 are both provided to directly meet the requirements for the air conditioner to deliver cold air and warm air through the heat exchange module. Compared with the case of delivering the coolant to the water pump and the water valve and then to the air outlet module of the air conditioner, the pipelines in the front engine compartment can be reduced, and the space utilization rate of the front engine compartment can be improved. Of course, in other embodiments, only the refrigerant flow channel 110 can be provided on the flow channel plate 100, and the coolant flowing into the condenser 201 and the evaporator 203 is distributed through the water pump and the water valve and then transported to the air outlet module of the air conditioner.
[0048] Further, in this embodiment, please refer to Figure 1 and Figure 2 , the heat exchange flow channel 120 communicates with the evaporator 203. Between the opposite side walls in the thickness direction of the flow channel plate 100, the heat exchange interface 121 is horizontally opened along the extension direction of the flow channel plate 100. It can be understood that the flow channel plate 100 extends in the vertical plane, the heat exchange flow channel 120 is distributed along the extension direction of the flow channel plate 100, and the heat exchange flow channel 120 also extends in the vertical plane. The heat exchange interface 121 communicating with the heat exchange flow channel 120 is arranged between the two opposite side walls of the flow channel plate 100 in the thickness direction, and the heat exchange part interface 121 is opened at the horizontal position of the flow channel plate 100. During the process of the refrigerant flowing along the heat exchange flow channel 120 to the pipeline connecting to the air outlet module of the air conditioner, large flow direction changes of the refrigerant can be avoided, thereby reducing the resistance of the refrigerant during the flow process, and thus improving the heat exchange efficiency of the refrigerant. In addition, the setting position of the heat exchange interface 121 avoids the heat exchanger, the liquid receiver dryer 204 and the throttling element 300, thereby avoiding interference between the pipeline connecting to the air outlet module of the air conditioner and the heat exchanger, the liquid receiver dryer 204 or the throttling element 300, and thus facilitating the flexible setting of the positions of the heat exchanger, the liquid receiver dryer 204 or the throttling element 300 on the flow channel plate 100 and improving the applicability of the heat exchange module. Of course, in other embodiments, the heat exchange interface 121 can also be arranged on the two side walls of the flow channel plate 100 distributed in the thickness direction.
[0049] Further, in this embodiment, please refer to Figure 2 , the heat exchange flow path 120 includes a first heat exchange flow path 122 and a second heat exchange flow path 123. The refrigerant flow path 110 is provided with a refrigerant interface 207 communicating with the compressor on the flow path plate 100. The first heat exchange flow path 122 communicates with the subcooler 202, and the second heat exchange flow path 123 communicates with the refrigerant interface 207. It should be noted that in the vehicle air conditioning system, the power of the cooling capacity condition is usually greater than that of the heating capacity condition. The first heat exchange flow path 122 communicates with the subcooler 202, and the refrigerant in this part is cooled and then directly transported to the air outlet module of the air conditioner through a pipeline, so as to meet the cooling capacity condition of the air conditioner. Then, when the evaporator at the air outlet module of the air conditioner converts this part of the low-temperature refrigerant into high-temperature refrigerant, it then flows back to the second heat exchange flow path 123, flows from the second heat exchange flow path 123 to the refrigerant interface 207, and then returns to the compressor together with the refrigerant in the main circulation loop. Thus, through the condenser 201 and the subcooler 202 in the heat exchange module, the demand for the cooling capacity condition of the air outlet module of the air conditioner is met, the number of interfaces of the compressor communicating with the outside is reduced, and further the number and complexity of the external pipelines are reduced, thereby improving the space utilization rate of the front engine compartment. Of course, in another embodiment, the coolant flowing through the condenser 201 or the evaporator 203 can also be transported from the coolant interface 206 of the heat exchange module to the water pump and the water valve, and adjusted by the water valve to the air outlet module of the air conditioner, the motor module, the battery module, the seat module, etc., so as to meet the demand for the heating capacity condition or the cooling capacity condition of the vehicle.
[0050] In one embodiment, please refer to Figures 1 to 3, the refrigerant flow path 110 includes a bypass flow path 130, and the throttling element 300 includes a regulating valve 302. The regulating valve 302 is arranged in parallel with the subcooler 202 between the condenser 201 and the evaporator 203. The bypass flow path 130 communicates with the condenser 201 and the regulating valve 302. It should be noted that for the refrigerant flowing through the bypass flow path 130, the pipeline for this refrigerant flow path in the condenser 201 does not exchange heat with the coolant flowing in the condenser 201. And after the bypass flow path 130 communicates with the condenser 201 and the throttling element 300, it then communicates with the compressor to form a bypass circuit, that is, the refrigerant circuit also includes a bypass circuit that is connected to the compressor in parallel with the main circulation circuit. In this way, through the refrigerant interface between the condenser 201 and the compressor, the refrigerant flow can be distributed to the bypass flow path and the main circulation flow path, reducing the pipelines and interfaces of the heat exchange module connected to the compressor, and improving the simplicity and compactness. At the same time, referring to the effect of the setting position of the expansion valve 301 described above, in this embodiment, the upstream component of the regulating valve 302 can be the condenser 201, and the regulating valve 302 is located between the evaporator 203 and the condenser 201 in the vertical direction. In this way, the length of the heat exchange flow path 120 connected between the regulating valve 302 and the condenser 201 can be shortened, improving the compactness of the heat exchange module. Of course, in other embodiments, the regulating valve 302 can also be arranged in parallel with the evaporator 203 or the condenser 201 in the horizontal direction, or the regulating valve 302 is connected to the compressor through a separate pipeline, or a three-way proportional valve is arranged on the pipeline connecting the compressor to the condenser 201 to distribute the refrigerant to the bypass circuit and the main circulation circuit.
[0051] In one embodiment, please refer to Figure 1 , the condenser 201 and the evaporator 203 are provided with coolant interfaces 206. The coolant interfaces 206 are used to communicate with the water pump or water valve of the vehicle. A plurality of heat exchangers are arranged on one side of the flow path plate 100 in the thickness direction, and the coolant interfaces 206 are formed on the side of the condenser 201 and the evaporator 203 facing away from the flow path plate 100. Without loss of generality, the water pump and the water valve are integrally arranged through the water-side flow path plate to form a water-side module. The water-side module and the heat exchange module can be distributed along the vehicle width direction or along the vehicle length direction. Here, the coolant interfaces 206 are formed on the side of the heat exchanger facing away from the flow path plate 100, that is, the coolant interfaces 206 of the heat exchange module are arranged in the same direction. In this way, in the operation of connecting the coolant interfaces 206 to the water pump or water valve, the operation convenience of connecting the coolant interfaces 206 to the pipeline can be improved. At the same time, the coolant interfaces 206 opened on the same side make the pipelines concentrated on one side of the heat exchange module, making the connecting pipelines between the heat exchange module and the water pump or water valve relatively neat, reducing the complexity of the pipelines in the front engine compartment, and facilitating the subsequent replacement or maintenance of the heat exchange module. Of course, in other embodiments, the coolant interfaces 206 can also be arranged on different sides of the heat exchanger to adapt to different water pumps or water valves with independent distributions.
[0052] In one embodiment, please refer to Figure 1 , refrigerant interfaces 207 are provided on the upper part of the flow channel plate 100 and the condenser 201. The refrigerant interfaces 207 communicate with the refrigerant flow channels 110 and are used to communicate with the compressor. Referring to the above description of the position of the condenser 201, the connection parts between the compressor and the heat exchange module are located at the upper and lower parts of the heat exchange module. The refrigerant directly communicates from the compressor to the condenser 201. The position where the refrigerant flows into the compressor from the evaporator 203 is at the upper part of the flow channel plate 100, shortening the flow path length of the refrigerant between the compressor and the condenser 201, improving the compactness of the heat exchange module. At the same time, it can also reduce the flow resistance of the refrigerant in the flow channel plate 100 and improve the heat exchange efficiency of the heat exchange module.
[0053] In one embodiment, please refer to Figure 1 and Figure 3 , the heat exchanger and the throttling element 300 are abutted against the flow channel plate 100. Connection ports are provided on the flow channel plate 100. The heat exchanger and the throttling element 300 cover and communicate with the corresponding connection ports. It can be understood that the heat exchanger and the throttling element 300 have side walls that fit against the flow channel plate 100. And at the joint between the heat exchanger and the throttling element 300 and the flow channel plate 100, the heat exchanger and the throttling element 300 are provided with communication ports, and the connection ports and the communication ports are in relative communication. In this way, there is a tight connection relationship between the heat exchanger or the throttling element 300 and the flow channel plate 100, improving the compactness of the heat exchange module. At the same time, after the heat exchanger or the throttling element 300 abuts against the flow channel plate 100, that is, the heat exchanger or the throttling element 300 communicates with the corresponding refrigerant flow channel 110, simplifying the installation process of the heat exchanger or the throttling element 300. Of course, in other embodiments, the heat exchanger and the throttling element 300 can also be connected to the flow channel plate 100 by protruding a communication ring on the flow channel plate 100 and screwing the heat exchanger or the throttling element 300 onto the corresponding communication ring.
[0054] Furthermore, in this embodiment, please refer to Figure 1 and Figure 3, a plurality of connecting lugs 205 protruding outward are distributed on the peripheries of the heat exchanger and the throttling element 300, and the connecting lugs 205 are connected to one side of the flow channel plate 100 that abuts against the heat exchanger or the throttling element 300. It can be understood that the connecting lugs 205 also abut against the flow channel plate 100. In this way, the connection relationship between the connecting lugs 205 and the flow channel plate 100 provides stable support and positioning for the heat exchanger and the throttling element 300, ensuring that they will not loosen or shift due to vibration or external forces during operation. At the same time, the connecting lugs 205 are exposed on the outer peripheries of the heat exchanger and the throttling element 300, enabling installers to more conveniently and quickly fix the heat exchanger and the throttling element 300 on the flow channel plate 100 without additional fixing parts or complex installation steps. Without loss of generality, at the abutting positions of the heat exchanger and the throttling element 300 and the flow channel plate 100, a sealing ring is clamped around the periphery of the connection port, and the close fit between the connecting lugs 205 and the flow channel plate 100 is utilized to press against the sealing ring, thereby reducing the risk of refrigerant leakage and improving the sealing performance of the heat exchange module. Of course, in other embodiments, internal threads can also be provided on the periphery of the connection port, and external threads can be provided on the outer peripheries of the heat exchanger and the throttling element 300, and then the heat exchanger and the throttling element 300 can be installed on the flow channel plate 100 by means of threaded connection.
[0055] In one embodiment, please refer to Figure 4 and Figure 5 , the heat exchanger is arranged on one side of the flow channel plate 100 in the thickness direction, and the liquid storage dryer 204 is arranged on the other side of the flow channel plate 100 in the thickness direction. It should be noted that the volume of the liquid storage dryer 204 is relatively large, and the heat exchanger and the liquid storage dryer 204 can be compactly installed on both sides of the flow channel plate 100, saving the space inside the front engine compartment and helping to improve the overall layout and design flexibility of the vehicle. For example, the liquid storage dryer 204 can be adjacent to the side edge in the extending direction of the flow channel plate 100 to avoid interference between the liquid storage dryer 204 and other components in the front engine compartment, or the liquid storage dryer 204 is in the middle of the plane where the flow channel plate 100 is distributed in the thickness direction.
[0056] The present utility model also proposes a thermal management device, which includes a water side module and a heat exchange module. The specific structure of the heat exchange module refers to the above embodiments. Since this thermal management device adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here.
[0057] Among them, the water-side module includes components such as a water-side flow channel plate, a water pump, and a water valve. The water pump and the water valve are integrally arranged on the water-side flow channel plate and are connected through the water-side flow channel of the water-side flow channel plate. The water-side flow channel plate is connected to the heat exchanger to realize the distribution of the coolant after heat exchange by the heat exchange module to each heat exchange position to be heated in the vehicle, improve the richness of the vehicle thermal management mode, reduce the space occupied by the thermal management device, and improve the space utilization rate of the front engine compartment.
[0058] Further, in this embodiment, the thermal management device further includes a front heat dissipation module. The water-side module, the compressor, and the heat exchange module are distributed along the Y direction of the vehicle. The front heat dissipation module extends obliquely downward from the front side of the water-side module and the heat exchange module, and the external pipeline connecting the water-side module and the heat exchange module is installed on the rear end face of the front heat dissipation module. It can be understood that along the length direction of the vehicle, the front heat dissipation module is located on the front side of the column where the heat exchange module is located and extends forward and downward from the water-side module and the heat exchange module, thereby releasing the upper space of the front heat dissipation module to increase the space of the front storage compartment. Among them, the front end face of the front heat dissipation module is the front lower side end face of the front heat dissipation module, and the rear end face of the front heat dissipation module is the rear upper side end face of the front heat dissipation module. At the same time, the external pipeline is arranged between the front heat dissipation module and the column where the heat exchange module is located, making the pipe fittings layout in the engine compartment more regular, improving the space utilization rate of the front engine compartment, and facilitating the installation and later maintenance of each component in the front engine compartment. It should be noted that the front heat dissipation module is used for the coolant to flow, and when the external air flows into the front heat dissipation module, it can dissipate the heat of the coolant to the outside of the vehicle to achieve the heat dissipation effect. In addition, the water-side module integrates multiple water pumps and water valves, and the water pumps and water valves are connected through the flow channel plate or pipeline and are connected to the heat exchange module through the integrated pipeline to obtain the heat-exchanged coolant from the heat exchange module and distribute the heat-exchanged coolant to each heat exchange position to be heated in the vehicle to ensure that the temperature of each part of the vehicle is within the preset range. The front heat dissipation module is connected to the water-side module to supply the high-temperature coolant after heat exchange to flow, and when the external air flows into the front heat dissipation module, it can dissipate the heat of the coolant to the outside of the vehicle to achieve the purpose of heat dissipation.
[0059] The present invention also proposes a vehicle, which includes a thermal management device. The specific structure of the thermal management device refers to the above embodiment. Since this vehicle adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, the thermal management device is installed in the front engine compartment of the vehicle, can be adjacent to the vehicle machine module, the battery module, and the motor module, reduce the length of the pipelines connected to each other, and reduce the heat loss of the coolant during the transmission process, and improve the efficiency of the thermal management device in controlling the temperature of the vehicle.
[0060] In one embodiment, the flow channel plate extends along the Y direction. The liquid storage and dryer is arranged at the rear side of the flow channel plate, and the heat exchanger is arranged at the front side of the flow channel plate. The coolant interface of the heat exchanger communicating with the water side module is arranged forward. It should be noted that the front heat dissipation module is at the front side of the heat exchange module, and there is an accommodation space for installing pipe fittings formed between the side where the heat exchange module is located. The water side module and the heat exchange module are arranged along the Y direction and are connected through the pipeline in the accommodation space. In this way, with the coolant interface arranged forward, the winding length of the pipe fittings can be reduced, which not only facilitates the installation of the pipe fittings, but also reduces the path length of heat transfer, reduces heat loss. At the same time, it can also avoid overly complex arrangement of the pipe fittings, reduce the occupied space in the front engine compartment, thereby improving the space utilization rate of the front engine compartment.
