[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Reference below Figure 1-Figure 4 Describe the thermal management module according to the embodiment of the present invention. It should be noted that the thermal management module in the present invention can be used in the heat exchange system of the vehicle, and the thermal management module can be used as a refrigerant module in the heat exchange system. In other words, the thermal management module is configured to use the refrigerant phase change to exchange heat to achieve the temperature control function. When used in the whole vehicle, the thermal management module can be used in conjunction with the water side component for heat exchange, so that the thermal management module can exchange heat with the water side component in the heat exchange system, so that the water medium in the water side component can be adjusted to different temperature states, thereby achieving heating and cooling of the components inside the vehicle or cooling and heating of the space inside the vehicle. In other words, the thermal management module is mainly used for circulating refrigerant, and for heat exchange with the water side component, so as to be used together to achieve temperature regulation in the vehicle. Among them, the water side component can be connected to the flow channel that needs heat exchange to form a water circulation loop, such as the heat exchange flow channel with the cockpit, the heat exchange flow channel with the battery, etc.

[0030] like Figure 1-Figure 4 As shown, a thermal management module according to an embodiment of the present invention includes: a liquid reservoir 17 , a valve device 18 , a heat exchanger 10 and a main body 100 .

[0031] Among them, the main body 100 is connected with a liquid reservoir 17, a valve device 18 and a heat exchanger 10, and the main body 100 is formed with a built-in flow channel for circulating refrigerant. The liquid reservoir 17, the valve device 18 and the heat exchanger 10 are all connected to the main body 100 and are respectively connected to the built-in flow channel; the valve device 18 at least includes one or more of a solenoid valve, an electronic expansion valve and a one-way valve. The solenoid valve is responsible for the opening and closing of the flow channel to match the switching of each mode flow path. The electronic expansion valve is responsible for throttling the fluid flow and pressure in the flow channel to achieve the temperature requirements in different modes. The one-way valve is a control valve for the direction of fluid flow, which only allows one-way circulation, so as to play a role in preventing backflow in a specific mode and ensure the normal operation of the mode; the heat exchanger can simultaneously realize the energy exchange between the refrigerant and water or between the refrigerant and the refrigerant. The liquid reservoir 17 includes a liquid storage chamber, a liquid return pipe and a desiccant, which is used to store the excess refrigerant liquid that does not participate in the circulation in the system to ensure the normal operation of the system.

[0032] Specifically, the valve device 18 and the heat exchanger 10 can be respectively arranged on different sides of the main body 100 to maximize the use of the installation space on different sides of the main body 100 and increase the integration of the liquid reservoir 17, the valve device 18 and the heat exchanger 10 with the main body 100.

[0033] The main body 100 includes a first temperature zone 1 and a second temperature zone 4, and the main body 100 includes multiple built-in flow channels, and a part of the built-in flow channel is located in the first temperature zone 1 and another part is located in the second temperature zone 4. Moreover, the valve device 18 may include multiple valves, and the multiple valves are spaced and distributed on one side of the main body 100, which are used to communicate with the built-in flow channel and can change the pressure of the built-in flow channel, so that the pressure and temperature of the refrigerant set in the built-in flow channel change. At the same time, the refrigerant in the built-in flow channel is also connected to the heat exchanger to exchange heat with the liquid inside the heat exchanger 10, that is, after the refrigerant exchanges heat with the heat exchanger, it flows to the first temperature zone 1 or the second temperature zone 4 of the main body 100.

[0034] Among them, the center of the first temperature zone 1 is separated from the second temperature zone 4, and when the thermal management module is running, the temperature of the first temperature zone 1 is higher than that of the second temperature zone 4. In other words, the first temperature zone 1 is a high temperature zone, and the second temperature zone 4 is a low temperature zone or a medium temperature zone. The valve can be used to control the flow to the high temperature zone or low temperature zone of the built-in flow channel, or to the pipeline inside the thermal management component outside the vehicle, so that the compressor, the heat exchanger and the first temperature zone 1 or the second temperature zone 4 form a cold and hot cycle, and the cold and hot cycle is completed at the same time, and the integration is high, and the main body 100 is highly integrated with the thermal management component outside the vehicle. In this way, the high temperature zone and the medium and low temperature zones can be set separately. It should be noted that the built-in flow channel may include multiple sub-flow channels. When the actual thermal management module is running, some of the sub-flow channels are high temperature flow channels, and some are low temperature flow channels. By setting different temperature zones separately, the high temperature flow channel in the high temperature zone and the low temperature flow channel in the medium and low temperature zone will not have too much heat exchange, thereby avoiding high and low temperature heat transfer and improving system performance.

[0035] According to the thermal management module of the embodiment of the present invention, the liquid reservoir 17, the valve device 18 and the heat exchanger 10 are integrated in the main body 100, which improves the integration and saves the installation space required for the thermal management module as a whole. At the same time, the main body 100 can realize the division of different temperature zones, so that the mutual influence between the different temperature flow channels of the built-in flow channels is smaller, avoiding high and low temperature heat transfer, improving the performance of the thermal management module, and thus ensuring the heat exchange efficiency of the thermal management module.

[0036] In some embodiments, two first temperature zones 1 are provided, the two first temperature zones 1 are spaced apart from the second temperature zone 4 , and the parts of the built-in flow channel located in the two first temperature zones 1 are connected through external components.

[0037] In practice, the first temperature zone 1 is a high temperature zone, and the second temperature zone 4 is a low temperature zone or a medium-low temperature zone. Figure 1 As shown, in the length direction of the main body 100, the high temperature zone is located at the lower position on both sides of the length direction of the main body 100, and the remaining area can be the second temperature zone 4, and the first temperature zone 1 is connected with the second temperature zone 4. At the same time, the first temperature zone 1 is also connected with the external compressor and heat exchanger 10. On the entire path where the main body 100 is connected with the compressor and the heat exchanger 10, some refrigerant flows to the low temperature zone or the medium and low temperature zone, and is connected with the structure outside the main body 100 through the low temperature zone or the medium and low temperature zone. The heating and cooling of the refrigerant during the entire circulation process can flow through the built-in flow channel inside the main body 100, and is connected with the structure outside the built-in flow channel.

[0038] In this way, the two high-temperature zones and the medium and low-temperature zones can be separated. The first temperature zone 1 and the second temperature zone 4 are separated, so that more high-temperature flow channels can be distributed separately from the low-temperature flow channels, thereby better avoiding high and low temperature heat transfer and improving the heat exchange performance of the system.

[0039] In some embodiments, the built-in flow channel includes multiple sub-flow channels, a portion of the multiple sub-flow channels is a first flow channel and another portion is a second flow channel, and when the thermal management module is operating, the pressure in the first flow channel is greater than the pressure in the second flow channel, at least a portion of the first flow channel is located in the first temperature zone 1, and the second flow channel is located in the second temperature zone 4.

[0040] Among them, refer to Figure 2 As shown, the first flow channel can be a high-pressure flow channel 6, and the second flow channel can be a low-pressure flow channel 7, wherein it should be noted that the high-pressure flow channel 6 is a flow channel relatively close to the outlet end of the compressor, and the refrigerant in this part of the flow channel is in a high-temperature and high-pressure state, and the low-pressure flow channel 7 is a flow channel relatively close to the inlet end of the compressor, and the refrigerant in this part of the flow channel is in a low-temperature and low-pressure state.

[0041] Specifically, the high-temperature and high-pressure gas coming out of the compressor outside the main body 100 can enter the high-pressure flow channel 6. When the high-temperature and high-pressure flow channel 6 is connected to the heat exchanger 10, after the high-temperature and high-pressure gas enters the heat exchanger 10 and exchanges heat with the heat exchanger 10 to become medium-temperature and low-pressure gas or medium-temperature and medium-pressure gas, it can flow through the heat exchanger 10 to the low-pressure flow channel 7 in the medium-temperature zone or low-temperature zone of the built-in flow channel.

[0042] Among them, most of the high-pressure flow channels 6 are set in the first temperature zone, and the low-pressure flow channels 7 are set in the second temperature zone, so that most of the high-pressure flow channels 6 and the low-pressure flow channels 7 can be effectively separated in the main body 100, avoiding the problem of heat cross-talk between the high-pressure flow channels 6 and the low-pressure flow channels 7, thereby ensuring that the refrigerant entering the heat exchanger 10 can reach the target temperature, ensuring the heat exchange efficiency of the heat exchanger, and improving the system performance of the thermal management module.

[0043] In some embodiments, the main body 100 is provided with a weight-reducing groove 3 between at least two adjacent sub-flow channels. First, the weight-reducing groove 3 can reduce the weight of the main body 100, making the main body 100 light and easy to install, and when the weight-reducing groove 3 is designed, it is easier to define the sub-flow channels between adjacent weight-reducing grooves 3, making the path of the sub-flow channels clearer, facilitating the identification of the sub-flow channels, and making the flow direction of the refrigerant in each sub-flow channel clearer for the entire circulation loop.

[0044] In some embodiments, there are multiple weight-reducing grooves 3 , and the first temperature zone 1 and / or the second temperature zone 4 is provided with at least one weight-reducing groove 3 .

[0045] In practice, a weight-reducing groove 3 may be provided between the plurality of high-pressure flow channels 6 of the first temperature zone 1, a weight-reducing groove 3 may be provided between the plurality of low-pressure flow channels 7 of the second temperature zone 4, and a weight-reducing groove 3 may also be provided at the connecting portion between the first temperature zone 1 and the second temperature zone 4, wherein the cross-sectional diameter of the weight-reducing groove 3 may be larger than the diameters of the high-pressure flow channel 6 and the low-pressure flow channel 7, so that more positions of the main body 100 have a certain weight reduction, and then, the weight of the main body 100 is lighter, and when the main body 100 is connected to the external vehicle thermal management components, the overall weight can also be made lighter.

[0046] In some embodiments, the main body 100 is provided with reinforcing ribs 5 between at least two adjacent sub-channels.

[0047] Specifically, the provision of the reinforcing ribs 5 can enhance the structural strength of the main body 100, and the reinforcing ribs 5 can be provided on one side of the flow path of the sub-channel, and partial reinforcing ribs 5 can be provided to enhance the strength of the main body 100 and the strength of the sub-channel, so that the sub-channel will not be greatly affected under a certain temperature or pressure.

[0048] In some embodiments, a heat insulation groove 2 is provided between at least one first flow channel and the second flow channel. Figure 2 As shown, the flow channel in the first temperature zone 1 is mainly the high-pressure flow channel 6, while the second temperature zone is provided with the high-pressure flow channel 6 and the low-pressure flow channel 7, wherein the high-pressure flow channel 6 located in the first temperature zone 1 can be well separated from the low-pressure flow channel 7, which can effectively reduce the problem of high and low temperature heat connection, and the high-pressure flow channel 6 and the low-pressure flow channel 7 located in the second temperature zone 1 can be insulated by setting the heat insulation groove 2, thereby further improving the heat insulation effect and realizing further optimization of high and low temperature heat connection.

[0049] Therefore, by setting the heat insulation groove 2 between the first flow channel and the second flow channel, the heat transfer between the first flow channel and the second flow channel can be reduced, which may affect the state of the refrigerant in the built-in flow channel and be detrimental to the normal circulation of the refrigerant.

[0050] In some embodiments, the valve device 18 includes an electronic expansion valve, and the first flow channel, the second flow channel and the electronic expansion valve are suitable for connecting with the compressor to form a circulation flow path, and the circulation flow path is connected to multiple heat exchange structures; wherein the first flow channel is connected between the compressor outlet 15 and the inlet end of the electronic expansion valve, and the second flow channel is connected between the outlet end of the electronic expansion valve and the inlet end of the compressor.

[0051] In practice, during refrigeration, the refrigerant is pressurized inside the compressor, which intensifies the molecular motion and increases the temperature. The refrigerant becomes a high-temperature and high-pressure gas. The refrigerant can then enter the heat exchanger 10 for heat exchange. After exchanging heat with the condenser, it will dissipate heat. After heat dissipation, the refrigerant becomes a cooled liquid, such as a high-pressure medium-temperature liquid. After the cooled liquid enters the electronic expansion valve, the temperature and pressure drop sharply. At this time, the refrigerant changes from a liquid to a low-temperature and low-pressure gas, and the low-temperature refrigerant coming out of the electronic expansion valve enters the evaporator. The evaporator also has an internal flow path, such as a coil. After the refrigerant enters the evaporator, the coil of the evaporator is quickly cooled, and the coil absorbs external heat to achieve a refrigeration effect. The refrigerant enters the air inlet end of the compressor again.

[0052] It should be noted that Figure 3 The shear head in the figure includes both the cooling part and the heating part. The specific refrigerant flow paths during cooling and heating are distinguished according to the following description.

[0053] Reference Figure 3 As shown, the refrigerant in the compressor outlet 15 flows to the first flow channel of the first temperature zone 1 on the right side of the main body 100, and flows to the second temperature zone 4 in the direction indicated by the shear head of the first flow channel, and flows to the Figure 3 The heat exchange internal flow path 14 on the upper right side of the middle, that is, the first flow path is a high-temperature flow path, and the refrigerant flows to the heat exchanger 10 shown in the figure through the high-temperature flow path, and the heat exchanger 10 is connected through the heat exchanger interface 12; and heat exchange begins in the heat exchange internal flow path 14 of the heat exchanger 10, and the heat exchanger 10 can be a condenser. After heat exchange, the refrigerant becomes a cooling liquid and directly reaches the position of the first electronic expansion valve 16 connected to the main body 100, and then flows to the first electronic expansion valve 16 through the first electronic expansion valve 16 Figure 3 The heat exchange internal flow path 14 on the upper left side of the middle part then flows to the low-pressure flow path 7 of the main body 100. At this time, the refrigerant also becomes a low-temperature and low-pressure liquid and flows inside the low-pressure flow path 7. Then, it flows to the flow path inside the evaporator through the low-pressure flow path 7. The evaporator is connected through the evaporator interface 11, and becomes a gas after heat exchange with the evaporator, and flows to the inlet of the compressor through the external pipeline.

[0054] During heating, similarly, the refrigerant is pressurized inside the compressor and becomes a high-temperature and high-pressure refrigerant. Then, it is selected through the switch valve 8, so that the high-temperature and high-pressure refrigerant enters the evaporator through valve control and becomes a medium-temperature liquid refrigerant and releases heat to heat the space where the heat exchanger is located. Then, it is depressurized through the throttle valve and becomes a low-temperature and low-pressure liquid refrigerant. It then absorbs heat through the condenser and becomes a low-temperature and low-pressure gas and enters the compressor.

[0055] That is, as shown in the diagram, when heating, the refrigerant flows to one first temperature zone 1 through the compressor, and flows to the other first temperature zone 1 through the area between the two first temperature zones 1. It should be noted that after the refrigerant flows from the first temperature zone 1 on the right side of the diagram to the inside of the first temperature zone 1 on the left side, the sub-channels in the first temperature zone 1 on the left side can pass through the liquid reservoir 17 flowing to the outside of the main body 100, and flow to another sub-channel in the first temperature zone 1 on the left side through the outlet of the liquid reservoir 17, thereby realizing the communication between the sub-channels in the first channel on the left side, and the refrigerant passes through the left side. When the first temperature zone 1 continues to flow to the second temperature zone 4, the high-temperature and high-pressure gas at this time flows through the internal flow path 9 of the liquid storage tank 17, and then flows to the evaporator interface 11 through the high-pressure flow channel 6 of the second temperature zone 4 and then flows to the evaporator, becoming a medium-temperature liquid refrigerant. It flows through the internal pipeline of the evaporator and then passes through the second electronic expansion valve 13 to become a low-temperature and low-pressure liquid, and then enters the low-pressure flow channel 7 of the main body 100. It is connected to the heat exchanger 10 of the main body 100 through the low-pressure flow channel 7 to become a low-temperature and low-pressure gas, and then flows to the inlet of the compressor through the pipeline outside the main body 100.

[0056] In some embodiments, the flow cross-sectional area of ​​the first flow channel is smaller than the flow cross-sectional area of ​​the second flow channel; and / or the flow cross-sectional area of ​​the second flow channel is greater than or equal to the area of ​​a circle with a diameter of 10 mm.

[0057] First, the first flow channel is a high-pressure flow channel 6. For example, the refrigerant flowing out of the compressor can flow through the first flow channel of the main body 100, and the cross-sectional area of ​​the first flow channel is smaller than the cross-sectional area of ​​the second flow channel. Then, the pressure reduction after flowing from the first flow channel through the external structure of the main body 100 to the second flow channel can be achieved by setting the flow cross-sectional areas of the first flow channel and the second flow channel to be different, and setting the pressures in the first flow channel and the second flow channel to be different, so as to meet the pressure change of the high pressure from the compressor or the low pressure from other heat exchangers flowing to the first flow channel or the second flow channel.

[0058] In addition, by setting the flow cross-sectional area of ​​the second flow channel to be greater than or equal to the cross-sectional area of ​​a circle with a diameter of 10 mm, the pressure of the refrigerant in the second flow channel can be kept at a lower state to prevent the state of the refrigerant from being affected and affecting the cooling or heating process. Of course, if a special refrigerant, such as carbon dioxide refrigerant, is encountered, the cross-sectional area of ​​the second flow channel shall not be less than the area of ​​a circle with a diameter of 3 mm. When setting the first flow channel, the flow cross-sectional area of ​​the first flow channel needs to be set smaller than that of the second flow channel.

[0059] In some embodiments, the height of the first flow channel is H1 and the width is L1, satisfying: 5mm≤H1≤12mm, 5mm≤L1≤10mm, and H1 / L1≤1.2; and / or, the height of the second flow channel is H2 and the width is L2, satisfying: 12mm≤H2≤20mm, 12mm≤L2≤20mm, and H2 / L2≤1.2.

[0060] In practice, by setting the height and width of the first flow channel, the volume of the refrigerant flowing into the first flow channel is limited, and the height and width of the second flow channel are both greater than the height and width of the first flow channel. Obviously, the volume of the second flow channel is greater than the volume of the first flow channel. At this time, the pressure of the same volume of refrigerant flowing into the first flow channel is greater than the pressure in the second flow channel. The refrigerant discharged through the structure outside the main body 100 has corresponding pressure and temperature, so that the refrigerant flows into the built-in flow channel of the main body 100. During the cooling and heating cycle, the pressure and temperature of the refrigerant flow into the built-in flow channel of the corresponding pressure and temperature, thereby maintaining the stability of the refrigerant during the entire cooling and heating cycle.

[0061] An embodiment of the present invention also discloses a vehicle, including the above-mentioned thermal management module, in which the vehicle thermal management component is connected to the built-in flow channel having the first temperature zone 1 and the second temperature zone 4 of the main body 100, which satisfies the high-temperature and low-temperature circulation flow path while saving the space occupied by the built-in flow channel and the vehicle management components, so that the entire thermal management module has a high degree of integration and the entire circulation process is more convenient.
