In related technologies, check valves are provided in the corresponding flow channels of the thermal management integrated module to prevent the medium from flowing back. However, the cost of the check valves is high, and there are moving parts, resulting in low reliability. Therefore, it is necessary to make improvements. Summary of the Invention

The communicating flow channel has a first cross-sectional area for fluid flow, and the lowest point of the first cross-sectional area for fluid flow is higher than the highest point of the second through port.

[0007] In some embodiments of the present application, the height difference between the lowest point of the first cross-sectional area for fluid flow and the highest point of the second through port is 1 mm to 100 mm.

[0008] In some embodiments of the present application, the other end of the communicating flow channel is provided with a first through port, and the communicating flow channel is connected to the first flow segment through the first through port. The first cross-sectional area for fluid flow is located between the first through port and the second through port.

[0010] In some embodiments of the present application, the check structure has a raised portion, and the highest point of the raised portion constitutes the lowest point of the first cross-sectional area for fluid flow.

[0011] In some embodiments of the present application, one side of the raised portion close to the first flow section is the first side, and the first side is inclined.

[0037] The first aspect of the present application discloses a thermal management integrated module 100, in combination with Figures 1 to 6As shown in the figure, the thermal management integrated module 100 includes a first flow channel 1000 and a check structure 3000. The first flow channel 1000 includes a first flow section 1100 and a second flow section 1200, while the check structure 3000 includes a connecting flow channel 3300. The two ends of the connecting flow channel 3300 are respectively connected to the first flow section 1100 and the second flow section 1200. Thus, when operating under normal conditions, the flow direction of the medium is from the first flow section 1100 through the connecting flow channel 3300 and then to the second flow section 1200. Among them, a second through port 3200 is provided at one end of the connecting flow channel 3300, and the connection between the connecting flow channel 3300 and the second flow section 1200 is achieved through the second through port 3200. And the connecting flow channel 3300 includes a first cross-sectional area of flow 3310, and the lowest point of the first cross-sectional area of flow 3310 is designed to be higher than the highest point of the second through port 3200.

[0038] By arranging the check structure 3000 in the first flow channel 1000, the backflow of the medium in the first flow channel 1000 can be prevented to a certain extent, which is beneficial to reducing the heat exchange inside the thermal management integrated module 100. The check structure 3000 is provided with a connecting flow channel 3300, and the lowest point of the first cross-sectional area of flow 3310 of the connecting flow channel 3300 is higher than the highest point of the second through port 3200 of the connecting flow channel 3300. In this way, the medium cannot flow reversely through the connecting flow channel 3300, that is, the backflow of the medium in the first flow channel 1000 is prevented. The check structure 3000 functions as a check valve. Compared with the traditional check valve, the check structure 3000 can prevent the backflow of the medium through the cooperation of the first cross-sectional area of flow 3310 and the second through port 3200, without the need to set up moving parts, the structure is simpler, which is beneficial to reducing costs and improving reliability.

[0039] Specifically, taking the application of the thermal management integrated module 100 to a vehicle 300 as an example, there are various components in the vehicle 300 that need thermal management. For example, it is necessary to heat and cool the cockpit of the vehicle 300, heat and cool the battery, dissipate heat from the motor and the electronic control unit, etc. The thermal management integrated module 100 is used to control the flow direction of the medium to the components that need thermal management, so as to conduct heat exchange to take away or supply heat to the corresponding components. It can be understood that the cockpit, battery, motor, electronic control unit, etc. are configured with corresponding heat exchange structures. The thermal management integrated module 100 is connected and communicated with the heat exchange structures so that the medium can realize circulation (the thermal management system 200 includes the connection and communication between the thermal management integrated module 100 and the heat exchange structures). The medium can flow from the thermal management integrated module 100 to the heat exchange structures, and can also flow from the heat exchange structures to the thermal management integrated module 100, thus forming a medium circulation. The medium is a carrier for heat exchange, for example, the medium is a refrigerant.

[0040] Inside the thermal management integrated module 100, there is a first flow channel 1000 through which the medium is transported. To prevent the medium from flowing back in the first flow channel 1000, a check valve needs to be set in the first flow channel 1000 in the related art. In this way, the medium can only flow along the first flow channel 1000 in a specific direction and cannot flow reversely.

[0041] For example, taking the medium as refrigerant and being transmitted in gaseous form under normal working conditions as an example for illustration. When the thermal management system 200 is in normal working conditions, the medium flows along the first flow channel 1000 in gaseous form. During the flow of the gaseous medium, a part of the gaseous medium exchanges heat with the flow channel wall of the first flow channel 1000 and becomes a liquid medium (such as becoming a liquid medium through heat conduction heat exchange). The liquid medium will flow back, and the liquid medium flows back and leaves the current position. Since the gaseous medium is continuously transmitted, liquid medium will be continuously generated. In this way, the internal heat exchange of the thermal management integrated module 100 is serious, reducing the energy efficiency of the thermal management system 200. Therefore, in the related art, by setting a check valve, the gaseous medium can only flow in a specific direction and flow through the check valve. When the liquid medium is generated, the liquid medium cannot flow reversely through the check valve, preventing the backflow of the liquid medium. Since the liquid medium does not flow back and leave the current position, the condensation of the subsequent flowing gaseous medium can be reduced, thereby reducing or even eliminating the internal heat exchange of the thermal management integrated module 100, and effectively improving the energy efficiency of the thermal management system 200. However, the check valve in the related art has a high cost and there are moving parts, with low reliability. It can be understood that the description of the function of the check valve is not limited to the above example and does not limit the protection scope of this application.

[0042] Therefore, in this embodiment, a check structure 3000 is set, and the check structure 3000 functions as a check valve to prevent the medium from flowing back. Specifically, the check structure 3000 is set in the first flow channel 1000, thereby dividing the first flow channel 1000 into a first flow section 1100 and a second flow section 1200. The check structure 3000 includes a communication flow channel 3300, and the first flow section 1100 and the second flow section 1200 are connected through the communication flow channel 3300. When the thermal management system 200 is in normal working conditions, the medium flows from the first flow section 1100 through the communication flow channel 3300 and then flows to the second flow section 1200.

[0043] In order to prevent the medium from flowing back, the connecting flow channel 3300 is improved as follows: a second opening 3200 is formed at one end of the connecting flow channel 3300, and the connecting flow channel 3300 is connected with the second flow segment 1200 through the second opening 3200. The medium flows into the connecting flow channel 3300 from the first flow segment 1100, and then flows out from the second opening 3200 and enters the second flow segment 1200. The connecting flow channel 3300 has a first flow section 3310 at other positions except the second opening 3200, that is, the first flow section 3310 is located upstream of the second opening 3200, and the lowest point of the first flow section 3310 is designed to be higher than the highest point of the second opening 3200, so that the medium can no longer flow from the second flow segment 1200 through the connecting flow channel 3300 to the first flow segment 1100, thereby preventing the medium from flowing back.

[0044] For example, still taking the medium as the refrigerant for explanation, when the thermal management system 200 is in normal operating conditions, the medium flows to the first flow segment 1100 in the form of gas, then flows through the connecting flow channel 3300, flows out from the second port 3200 and enters the second flow segment 1200, and part of the gaseous medium entering the second flow segment 1200 is condensed into a liquid medium. When the liquid medium flows back and enters the connecting flow channel 3300 through the second port 3200, the lowest point of the first flow section 3310 is higher than the highest point of the second port 3200, thereby forming a barrier to the liquid medium, and the liquid medium cannot flow through the first flow section 3310 and flow to the first flow segment 1100. Therefore, the liquid medium will accumulate in the first flow segment 1100, reducing the subsequent generation of the liquid medium, thereby reducing the heat exchange inside the thermal management integrated module 100, which is beneficial to improving the energy efficiency of the thermal management system 200. The cooperation between the first flow section 3310 and the second opening 3200 can prevent the backflow of the medium without setting any movable parts, which is beneficial to reducing costs and improving reliability.

[0045] It is understandable that the so-called first flow section 3310 is a cross section roughly orthogonal to the streamline of the medium, and can be regarded as a cross section formed by cutting the first flow section 1100 with a plane. Figure 3 The orientation shown is based on the normal installation of the thermal management integrated module 100 on the vehicle 300 as a reference. The side close to the ground is the bottom, the side away from the ground is the top, the side opposite to the left side of the vehicle 300 is the left, the side opposite to the right side of the vehicle 300 is the right, the side close to the front of the vehicle is the front, and the side close to the rear of the vehicle is the rear. A plane is defined, which extends in the up and down direction. The cross-section formed by intercepting the corresponding position of the first flow channel 1000 using this plane is the first flow section 3310.

[0046] In some embodiments of the present application, the lowest point of the first flow-through cross-section 3310 is 1 mm to 100 mm higher than the highest point of the second through-port 3200. It can be understood that as long as it is ensured that the lowest point of the first flow-through cross-section 3310 is higher than the highest point of the second through-port 3200, the backflow of the medium can be prevented. In this embodiment, by optimizing the height difference between the highest point of the second through-port 3200 and the lowest point of the first flow-through end face, it is avoided that the height difference between the highest point of the second through-port 3200 and the lowest point of the first flow-through end face is too small, which increases the processing difficulty, and at the same time, it is avoided that the height difference between the highest point of the second through-port 3200 and the lowest point of the first flow-through end face is too large, which leads to an excessive thickness of the thermal management integration module 100 and reduces the space occupied by the thermal management integration module 100. For example, the lowest point of the first flow-through cross-section 3310 is 1 mm, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 20 mm, 30 mm, 40 mm, 60 mm, 80 mm or 100 mm higher than the highest point of the second through-port 3200.

[0047] Combined Figures 4 to 6 As shown, in some embodiments of the present application, a first through-port 3100 is provided at the other end of the communication flow channel 3300. The communication between the communication flow channel 3300 and the first flow segment 1100 is achieved through the first through-port 3100. The first flow-through cross-section 3310 is arranged at any position between the second through-port 3200 and the first through-port 3100. This is beneficial to reducing the height difference between the first flow segment 1100 and the second flow segment 1200, and even makes the first flow segment 1100 and the second flow segment 1200 at the same height, which is more convenient for processing and is also beneficial to reducing the thickness of the thermal management integration module 100.

[0048] Specifically, the first cross-sectional area 3310 of the flow can be located at any position other than the second through-port 3200, that is, the first cross-sectional area 3310 of the flow can be between the two ends of the first flow channel 1000. The first cross-sectional area 3310 of the flow can also be at the other end of the connecting flow channel 3300 (one end of the connecting flow channel 3300 is provided with the second through-port 3200). Since the other end of the first cross-sectional area 3310 of the flow is provided with the first through-port 3100, that is, the end face of the first through-port 3100 constitutes the first cross-sectional area 3310 of the flow. Also, since the connecting flow channel 3300 needs to be connected to the first flow section 1100 through the first through-port 3100, and the lowest point of the first cross-sectional area 3310 of the flow is higher than the highest point of the second through-port 3200. That is to say, in this case, the first flow section 1100 also needs to be at a higher position to cooperate with the first through-port 3100, which results in a height difference between the first flow section 1100 and the second flow channel 2000. This will increase the thickness of the thermal management integrated module 100 and is also not conducive to the processing of the first flow section 1100 and the second flow section 1200. For example, the thermal management integrated module 100 is formed by docking the upper and lower parts to enclose the first flow channel 1000. The first flow channel 1000 is formed by cutting. Different heights of the first flow section 1100 and the second flow section 1200 require corresponding feed rates of different tools, and the processing efficiency is relatively low.

[0049] Therefore, in this embodiment, the first cross-sectional area 3310 of the flow is arranged between the first through-port 3100 and the second through-port 3200. The end face of the first through-port 3100 is not the first cross-sectional area 3310 of the flow. This is beneficial to optimizing the position of the first through-port 3100, thereby reducing the height difference between the first flow section 1100 and the second flow section 1200.

[0050] For example, in combination with Figure 6 As shown, the lowest point of the first cross-sectional area 3310 of the flow is higher than the lowest point of the first through-port 3100. This can reduce the height difference between the first flow section 1100 and the second flow section 1200, and even make the first flow section 1100 and the second flow section 1200 at the same level.

[0051] Specifically, relative to the lowest point of the first flow cross-section 3310, the lowest point of the first through-port 3100 is lower. Thus, the connection point between the first through-port 3100 and the first flow segment 1100 is also lower, which is beneficial to reducing the height difference between the first flow segment 1100 and the second flow segment 1200. By such a setting, it is even possible to make the first flow segment 1100 and the second flow segment 1200 at the same level (provided that the depths (in the up-down direction) of the first flow segment 1100 and the second flow segment 1200 are equal). This is beneficial to reducing the thickness of the thermal management integration module 100. When machining the first flow segment 1100 and the second flow segment 1200, it is not necessary to separately adjust the different feed rates of the cutting tools for the first flow segment 1100 and the second flow segment 1200, which is beneficial to improving the machining efficiency.

[0052] Combined with Figure 3 and Figure 6 As shown, in some embodiments of the present application, the check structure 3000 includes a raised portion 3400. Among them, the highest point of the raised portion 3400 is configured as the lowest point of the first flow cross-section 3310. By setting the raised portion 3400, it is more convenient to form the first flow cross-section 3310. Specifically, the surface of the raised portion 3400 constitutes the flow channel wall of the connected flow channel 3300. The raised portion 3400 is arranged at the bottom of the flow channel wall of the connected flow channel 3300 and bulges upward. In this way, the flow cross-section corresponding to the highest point of the raised portion 3400 can be lifted. Based on this, this flow cross-section is designed as the first flow cross-section 3310. In this way, it is more convenient to design the lowest point of the first flow cross-section 3310 (i.e., the highest point of the raised portion 3400) to be higher than the highest point of the second through-port 3200.

[0053] Combined with Figure 6 As shown, in some embodiments of the present application, the side of the raised portion 3400 close to the first flow segment 1100 is defined as the first side 3410. Among them, the first side 3410 needs to be designed to be inclined, which is more beneficial to the medium flowing from the first flow segment 1100 through the first through-port 3100 and into the connected flow channel 3300 under normal working conditions.

[0054] Specifically, as mentioned above, when in the normal working condition, the medium will flow to the first flow segment 1100 and then enter the connected flow channel 3300 through the first through-port 3100. Therefore, in this embodiment, by designing the first side 3410 to be inclined, it is equivalent to forming a slope to reduce the resistance of the medium flow. The inclination of the first side 3410 is inclined towards the direction where the second flow segment 1200 is located. It can be understood that the side of the raised portion 3400 close to the first flow segment 1100 is defined as the first side 3410. Here, the closeness is relative to the other side of the raised portion 3400. The other side of the raised portion 3400 is close to the second flow segment 1200 and is defined as the second side 3420.

[0055] Combined Figure 6 As shown, in some embodiments of the present application, the second side 3420 is also inclined. It can be understood that the inclination of the second side 3420 is towards the orientation where the first flow section 1100 is located. In this way, the intersection of the first side 3410 and the second side 3420 constitutes the highest point of the raised portion 3400. When the medium flows, it will pass through the first side 3410 and the second side 3420 in sequence. By designing the second side 3420 to be inclined as well, the occurrence of eddy currents in the flow of the medium is avoided, and the flow resistance of the medium is reduced.

[0056] Since the intersection of the first side 3410 and the second side 3420 constitutes the lowest point of the first flow cross-section 3310, the blocking of the backflow of the medium is achieved through the second side 3420. For this reason, the inclination of the second side 3420 is greater than that of the first side 3410. A greater inclination can be understood as being steeper, so as to more effectively block the backflow medium.

[0057] Combined Figure 1 and Figure 2 As shown, in some embodiments of the present application, the thermal management integration module 100 includes a seat body 5100 and a sealing plate 5200. The sealing plate 5200 covers the seat body 5100, thereby enclosing a first flow channel 1000 between the sealing plate 5200 and the seat body 5100.

[0058] Specifically, the first flow channel 1000 is inside the thermal management integration module 100. To facilitate the formation of the first flow channel 1000, the thermal management integration module 100 includes two parts, namely the seat body 5100 and the sealing plate 5200. The thickness of the seat body 5100 is greater than that of the sealing plate 5200. Corresponding grooves are machined on the seat body 5100. Grooves may or may not be machined on the sealing plate 5200. When the sealing plate 5200 covers the seat body 5100, the groove can be enclosed to form the first flow channel 1000, which is convenient and fast.

[0059] The seat body 5100 and the sealing plate 5200 can be processed from metal materials or other materials. To meet different installation requirements, the seat body 5100 and the sealing plate 5200 can be designed into regular shapes or irregular shapes. The connection between the seat body 5100 and the sealing plate 5200 can be achieved by screwing, or by welding, or by other means.

[0060] There are various ways to arrange the check valve structure 3000 in the first flow channel 1000. For example, the check valve structure 3000 can be separately prepared and installed into the first flow channel 1000. Combined Figure 3As shown, the check structure 3000 is clamped between the seat body 5100 and the cover plate 5200, thus realizing the installation of the check structure 3000. When corresponding grooves can be machined on the seat body 5100, an installation position is provided at a certain position between the two ends of the groove, and the check structure 3000 can be snapped into the installation position to achieve preliminary positioning and installation. Then, when the cover plate 5200 is covered on the seat body 5100, the fastening between the cover plate 5200 and the seat body 5100 clamps the check structure 3000, so that the check structure 3000 is located in the first flow channel 1000.

[0061] Of course, the check structure 3000 can also be arranged in the first flow channel 1000 in the following way. When machining the seat body 5100 or the cover plate 5200, the check structure 3000 is integrally machined on the seat body 5100 or the cover plate 5200, so that the number of components 4200 can be reduced.

[0062] The check structure 3000 can also be arranged in the first flow channel 1000 in the following way. The check structure 3000 includes two parts, one part is integrally arranged on the seat body 5100, and the other part is integrally arranged on the cover plate 5200. In this way, the difficulty of integral machining of the entire check structure 3000 can be reduced. When the seat body 5100 and the cover plate 5200 are assembled, the two parts of the check structure 3000 are matched to form a complete check structure 3000.

[0063] Combined Figure 1 and Figure 2 As shown, in some embodiments of the present application, the thermal management integration module 100 further includes a component installation cavity 4100. The second flow section 1200 communicates with the component installation cavity 4100, and the component installation cavity 4100 is used for installing components 4200.

[0064] For example, the component 4200 is a valve body. The component installation cavity 4100 is used for installing the valve body. The medium flows from the second flow section 1200 to the valve body and then flows out of the valve body. The valve body at least includes a solenoid valve, an electronic expansion valve, etc. The solenoid valve is responsible for the on-off of the medium flow to cooperate with the switching of each mode, and the electronic expansion valve is responsible for throttling control of the flow rate, pressure of the medium to meet the temperature requirements in different modes.

[0065] For another example, the component 4200 is a sensor. The component installation cavity 4100 is used for installing the sensor. When the medium flows to the component installation cavity 4100, it is detected by the sensor, and the current state of the medium can be obtained in real time, providing a basis for the dynamic adjustment of the entire medium cycle.

[0066] Combined Figure 2As shown, in some embodiments of the present application, the thermal management integration module 100 further includes a second flow channel 2000, and the second flow channel 2000 is in communication with the first flow channel 1000. Specifically, the second flow channel 2000 is in communication with the first flow segment 1100 of the first flow channel 1000. For example, the second flow channel 2000 intersects and communicates with the first flow segment 1100. By providing the second flow channel 2000, the thermal management integration module 100 has more flow paths. By providing the check structure 3000, the medium will not flow back to the second flow channel 2000.

[0067] A second aspect of the present application discloses a thermal management system 200, in combination with Figure 7 As shown, the thermal management system 200 includes the above-mentioned thermal management integration module 100, and the thermal management system 200 can achieve thermal management of different components. Taking the vehicle 300 as an example, there are various components in the vehicle 300 that need thermal management. For example, it is necessary to heat and cool the cockpit of the vehicle 300, heat and cool the battery, dissipate heat from the motor and the electronic control unit, etc. The thermal management integration module 100 is used to control the flow direction of the medium to the components that need thermal management, so as to exchange heat and take away or supply heat to the corresponding components. The cockpit, battery, motor, electronic control unit, etc. are configured with corresponding heat exchange structures, and the thermal management integration module 100 is connected and communicated with the heat exchange structures so that the medium can circulate (the thermal management system 200 includes the connection and communication between the thermal management integration module 100 and the heat exchange structures).

[0068] The thermal management integration module 100 includes a first flow channel 1000 and a check structure 3000. The first flow channel 1000 includes a first flow segment 1100 and a second flow segment 1200, and the check structure 3000 includes a communication flow channel 3300. Both ends of the communication flow channel 3300 are respectively in communication with the first flow segment 1100 and the second flow segment 1200. Thus, when operating under normal conditions, the flow direction of the medium is from the first flow segment 1100 through the communication flow channel 3300 and then to the second flow segment 1200; wherein, one end of the communication flow channel 3300 is provided with a second port 3200, and the communication between the communication flow channel 3300 and the second flow segment 1200 is achieved through the second port 3200, and the communication flow channel 3300 includes a first flow cross-section 3310, and the lowest point of the first flow cross-section 3310 is designed to be higher than the highest point of the second port 3200.

[0069] By providing a check structure 3000 in the first flow channel 1000, the backflow of the medium in the first flow channel 1000 can be prevented to a certain extent, which is beneficial to reducing the heat exchange within the heat management integration module 100. The check structure 3000 is provided with a communicating flow channel 3300, and the lowest point of the first flow cross-section 3310 of the communicating flow channel 3300 is higher than the highest point of the second port 3200 of the communicating flow channel 3300. In this way, the medium cannot flow reversely through the communicating flow channel 3300, that is, the backflow of the medium in the first flow channel 1000 is prevented. The check structure 3000 functions as a one-way valve. Compared with the traditional one-way valve, the check structure 3000 can prevent the backflow of the medium through the cooperation of the first flow cross-section 3310 and the second port 3200, without the need to provide moving parts, and the structure is simpler, which is beneficial to reducing costs and improving reliability. It can be understood that the heat management integration module 100 in the heat management system 200 adopts the technical solution of the above embodiment, and thus at least has the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0070] The third aspect of the present application discloses a vehicle 300, which combines Figure 8 As shown, the vehicle 300 includes the above heat management system 200. The vehicle 300 can be a new energy vehicle. The new energy vehicle can be a pure electric vehicle with an electric motor as the main driving force, or a hybrid vehicle with an internal combustion engine and an electric motor as the main driving forces at the same time. The internal combustion engine and the electric motor that provide driving power for the aforementioned new energy vehicle, where the internal combustion engine can use gasoline, diesel, hydrogen, etc. as fuel, and the way to provide electrical energy for the electric motor can use a power battery, a hydrogen fuel cell, etc., which are not specifically limited here. It should be noted that only an exemplary description of the structure of the new energy vehicle, etc. is made here, and it does not limit the protection scope of the present invention. Since the heat management system 200 of the vehicle 300 adopts the technical solution of the above embodiment, it thus at least has the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.
