[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] like Figures 1 to 3 As shown, the integrated flow channel plate of this embodiment includes a refrigerant plate 100 and a cover plate 200. The refrigerant plate 100 is provided with multiple flow channel grooves and flow channel connectors, and the multiple flow channel grooves are connected by the flow channel connectors. The cover plate 200 includes multiple encapsulation parts 210 and connecting parts 220. The multiple encapsulation parts 210 correspond one-to-one with the multiple flow channel grooves, and the encapsulation parts 210 are closedly connected to the corresponding flow channel grooves to form a refrigerant flow channel. The refrigerant flow channel is provided with an inlet and an outlet. Different encapsulation parts 210 are connected to each other through the connecting parts 220. The cover plate 200 is also provided with an air intake 230 and an air exhaust 240, which are respectively provided on two different encapsulation parts 210.

[0034] Based on the above design, multiple flow channel grooves on the refrigerant plate 100 are connected to form a whole through flow channel connectors, and multiple encapsulation parts 210 on the cover plate 200 are connected to form a whole through connecting parts 220. The encapsulation parts 210 are arranged one-to-one with the flow channel grooves and can be closed to form a refrigerant flow channel. By connecting the inlet and outlet of each refrigerant flow channel to different components in the thermal management system, multiple components are connected in series. This integrated flow channel plate can replace the traditional cooling pipes to connect automotive thermal management components, integrate and install refrigerant-side components, realize the integration of the thermal management system, improve energy utilization efficiency, simplify refrigerant piping, reduce weight and cost, increase space compactness, reduce final assembly time, reduce maintenance costs, and help improve the stability of the thermal management system.

[0035] In some embodiments, the flow channel body and flow channel connector of the refrigerant plate 100, the encapsulation part 210 and the connecting part 220 of the cover plate 200, and the refrigerant plate 100 and the cover plate 200 can all be connected by welding, such as laser welding, brazing, etc., which are mature processes and help save manufacturing costs. In some other embodiments, the refrigerant plate 100 and the cover plate 200 can also be die-cast, which simplifies the production process of the refrigerant plate 100 and the cover plate 200 and can avoid process defects caused by too many welding steps, which is beneficial to improving product quality.

[0036] Specifically, the refrigerant plate 100 is provided with a first flow channel 120, a second flow channel 130, a third flow channel 140 and a fourth flow channel 150. The first flow channel 120 is provided with a first outlet 121, which is connected to the condenser inlet. The cover plate 200 includes a first encapsulation plate 211, which is closedly connected to the first flow channel 120 to form a first refrigerant flow channel. The suction port 230 is provided on the first encapsulation plate 211 and is connected to the compressor outlet. The high-temperature refrigerant gas flowing out from the compressor flows into the condenser through the first refrigerant flow channel for cooling.

[0037] Optionally, the integrated flow channel plate also includes a first sensor 300, which is connected to the first flow channel groove 120. The first sensor 300 can measure the temperature and pressure of the high-temperature refrigerant gas flowing out of the compressor outlet, helping the thermal management system maintain a suitable temperature, ensuring that the compressor operates within the optimal operating temperature range and under appropriate pressure, thereby optimizing the compressor's performance, reducing the probability of failure, extending the compressor's lifespan, and ensuring the stability and reliability of the thermal management system.

[0038] Furthermore, the second flow channel 130 is provided with a first inlet 131 and a second outlet 132. The first inlet 131 is connected to the condenser outlet, and the second outlet 132 is connected to the storage tank inlet. The cover plate 200 includes a second sealing plate 212, which is closedly connected to the second flow channel 130 to form a second refrigerant flow channel. When the refrigerant flows out of the condenser, it enters the storage tank through the second refrigerant flow channel, realizing the storage and circulation of the refrigerant, ensuring that the system can supply refrigerant in a timely manner when needed, and reducing safety risks.

[0039] Furthermore, the third flow channel 140 is provided with a second inlet 141 and a third outlet 142. The second inlet 141 is connected to the outlet of the storage tank, and the third outlet 142 is connected to the inlet of the evaporator. The cover plate 200 also includes a third encapsulation plate 213, which is enclosedly connected to the third flow channel 140 to form a third refrigerant flow channel. When the thermal management system needs cooling, the refrigerant flows out from the storage tank and enters the evaporator through the third refrigerant flow channel, causing the refrigerant to evaporate into a gaseous state, thereby achieving a cooling effect.

[0040] Optionally, the third flow channel 140 is also provided with a mounting base 143 for mounting an expansion valve. The expansion valve throttles the medium- and high-pressure liquid refrigerant into low-temperature, low-pressure wet vapor, creating the necessary conditions for refrigerant evaporation, achieving the function of throttling and pressure reduction, and maintaining system stability. It is understood that the third encapsulation plate 213 is enclosedly connected to the third flow channel 140 between the second inlet 141 and the mounting base 143, thereby reducing the length of the third encapsulation plate 213 and lightening the weight of the cover plate 200.

[0041] Furthermore, the fourth flow channel 150 is provided with a third inlet 151, which is connected to the evaporator outlet. The cover plate 200 also includes a fourth encapsulation plate 214, which is enclosed and connected to the fourth flow channel 150. The fourth encapsulation plate 214 is provided with an exhaust port 240, which is connected to the compressor inlet, so that the gaseous refrigerant flowing out of the evaporator flows to the compressor.

[0042] Optionally, the integrated flow channel plate also includes a second sensor 400, which is connected to the fourth flow channel 150. The second sensor 400 is used to measure the temperature and pressure of the refrigerant gas entering the compressor from the evaporator, thereby monitoring the operating status of the evaporator.

[0043] Optionally, the refrigerant plate 100 is also provided with a charging port 250, which is located in the fourth flow channel groove 150, and a charging valve is provided at the charging port 250. When the refrigerant in the refrigerant plate 100 is lost during use, refrigerant can be added to the fourth flow channel groove 150 through the charging port 250, so that there is a sufficient amount of refrigerant circulating in the refrigerant flow channel, ensuring a good cooling effect of the thermal management system.

[0044] In this embodiment, the flow channel connector 110 includes a square frame 111 and several fasteners 112. The square frame 111 constitutes the external frame structure of the refrigerant plate 100, and the fasteners 112 are used to connect the square frame 111 and multiple flow channel grooves to ensure the structural stability of the refrigerant plate 100. It should be noted that the square frame 111 and the fasteners 112 can be connected to any position in the flow channel groove as needed, and the number of connection positions can also be adjusted to form a hollow structure between the fasteners 112 and the square frame 111. This helps to reduce the weight of the refrigerant plate 100, save manufacturing costs, and ensure the rationality and stability of the structure. For example, the fasteners 112 can be in the form of a straight line, an L-shape, a T-shape, etc., and their specific shapes can be adjusted according to the installation position and the relative positions of the components to avoid interference.

[0045] Optionally, the flow channel connector 110 also includes multiple mounting sleeves 113, which are distributed on the square frame 111 and the fastener 112 for inserting external components to achieve a fixed connection between the refrigerant plate 100 and external equipment. Optionally, the mounting sleeves 113 are provided with threaded holes and are fixed by threaded connection with bolts, which is simple in structure and easy to manufacture.

[0046] Furthermore, the cover plate 200 includes a first connector 221, a second connector 222, and a third connector 223. The first connector 221 is connected between the first encapsulation plate 211 and the second encapsulation plate 212, the second connector 222 is connected between the second encapsulation plate 212 and the third encapsulation plate 213, and the third connector 223 is connected between the third encapsulation plate 213 and the fourth encapsulation plate 214, thereby achieving the overall connection of the cover plate 200. Optionally, different connectors can also be interconnected to form an integral structure of the cover plate 200, which will not be elaborated further here.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
