In the field of commercial vehicles, considering energy consumption savings, vehicle thermal management solutions have become more complex.

[0003] In order to increase the driving range of electric vehicles, there are more and more requirements for the working condition design of the vehicle's overall thermal management, and the number of components required in the thermal management system also increases correspondingly.

[0028] Next, the embodiments of this application will be described in detail.

[0029] As Figure 1 shown, this application provides a thermal management integrated valve, which includes a manifold plate 10, a seven-way valve 20, a three-way valve 30, a first water temperature sensor 41, a second water temperature sensor 42, a water-water heat exchanger 50, and a battery cooling heat exchanger 60.

The hot side of the battery cooling heat exchanger 60 is connected to the battery thermal management circuit, and the cold side is connected to the air-conditioning refrigeration circuit.

[0032] By integrating and fixing the seven-way valve 20, the three-way valve 30, the first water temperature sensor 41, the second water temperature sensor 42, the water-water heat exchanger 50 and the battery cooling heat exchanger 60 on the manifold 10, the integration of parts and pipelines is achieved, reducing the problem of a large variety of valve parts in the thermal management system. At the same time, the pipeline splicing is reduced, the layout space is saved, the risk of pipeline leakage is reduced, and the reliability and safety are improved.

[0033] Please refer to Figure 2 and Figure 3 , there is a coolant flow channel 11 arranged in the manifold 10 for guiding and distributing the coolant to flow into or out of different components in the thermal management integrated valve. The seven-way valve 20, the three-way valve 30, the water-water heat exchanger 50 and the battery cooling heat exchanger 60 are all connected to the coolant flow channel 11. The seven-way valve 20 includes seven valve ports A, B, C, D, E, F, G, and the three-way valve 30 includes three valve ports K, H, J. The valve ports of the seven-way valve 20 and the three-way valve 30 are all connected to the coolant flow channel 11.

[0034] The valve port A of the seven-way valve 20 is connected to the cold side of the water-water heat exchanger 50, and the battery cooling heat exchanger 60 is connected to the cold side of the water-water heat exchanger 50. The valve port J of the three-way valve 30 is connected to the hot side of the water-water heat exchanger 50.

[0035] Furthermore, a plurality of seven-way valve interfaces 12 and a plurality of three-way valve interfaces 13 are also provided on the manifold 10. The plurality of seven-way valve interfaces 12 are connected to the seven valve ports of the seven-way valve 20 through the coolant flow channel 11, and the plurality of three-way valve interfaces 13 are connected to the three valve ports of the three-way valve 30 through the coolant flow channel 11.

[0036] Please refer to Figures 3 to 5 , specifically, the seven-way valve interface 12 includes a first interface 121, a second interface 122, a third interface 123, a fourth interface 124, a fifth interface 125, a sixth interface 126, a seventh interface 127 and an eighth interface 128.

[0037] Inside the thermal management integrated valve, the first interface 121 is connected to the hot-side liquid inlet of the battery cooling heat exchanger 60, and is sequentially connected to the water-water heat exchanger 50 through the battery cooling heat exchanger 60 and then to the valve port A of the seven-way valve. The second interface 122 is connected to the valve port B of the seven-way valve. The third interface 123 is connected to the valve port C of the seven-way valve. The fourth interface 124 is connected to the valve port D of the seven-way valve. The fifth interface 125 and the eighth interface 128 are both connected to the valve port E of the seven-way valve, the sixth interface 126 is connected to the valve port F of the seven-way valve, and the seventh interface 127 is connected to the valve port G of the seven-way valve.

[0038] The coolant flow path of the eighth interface 128 and the coolant flow path of the fifth interface 125 are connected to the valve port E of the same seven-way valve 20, so as to realize the simultaneous convergence of the coolant at two different components in the electric drive thermal management circuit to the valve port E.

[0039] The valve port A of the seven-way valve can be selectively connected to one of the valve port B or the valve port D, and the valve port C of the seven-way valve can be selectively connected to the other of the valve port B or the valve port D, so as to realize the independent or connected switching between the battery thermal management circuits. The valve port E of the seven-way valve can be selectively connected to one of the valve port F or the valve port G, so as to realize the switching of the heat dissipation mode in the electric drive thermal management circuit.

[0040] That is to say, the first interface 121 can be selectively connected to one of the second interface 122 or the fourth interface 124 through the seven-way valve 20, and the third interface 123 can be selectively connected to the other of the second interface 122 or the fourth interface 124 through the seven-way valve 20. The fifth interface 125 can be selectively connected to one of the sixth interface 126 or the seventh interface 127 through the seven-way valve 20.

[0041] The three-way valve interface 13 includes a ninth interface 131, a tenth interface 132 and an eleventh interface 133. Inside the thermal management integrated valve, the ninth interface 131 is connected to the valve port K of the three-way valve 30, the tenth interface 132 is connected to the valve port H of the three-way valve 30, and the eleventh interface 133 is connected to the valve port J of the three-way valve 30 through the water-water heat exchanger 50.

[0042] The valve port K of the three-way valve 30 can be selectively connected to the valve port H or the valve port J, so as to realize the heat supply from the heating circuit to the cockpit or the battery thermal management circuit. In some cases, the valve port K of the three-way valve 30 is connected to one of the valve port H or the valve port J. In some cases, the valve port K of the three-way valve 30 can also be connected to both the valve port H and the valve port J at the same time.

[0043] In this way, the ninth interface 131 can be selectively connected to the tenth interface 132 or the eleventh interface 133 through the three-way valve 30. The ninth interface 131 can be connected to one of the tenth interface 132 or the eleventh interface 133, or can also be connected to both the tenth interface 132 and the eleventh interface 133 at the same time.

[0044] It can be understood that the connection relationships between the various interfaces in the thermal management integrated valve, the number of interfaces, the connection relationships of the various valve ports of the seven-way valve 20, and the connection relationships of the various valve ports of the three-way valve 30 can all be flexibly designed according to the actual needs of the vehicle thermal management system, and the present application does not limit them here.

[0045] The first water temperature sensor 41 is used to detect the water temperature at the third interface 123, and the second water temperature sensor 42 is used to detect the water temperature at the fifth interface 125. By integrally arranging the first water temperature sensor 41 and the second water temperature sensor 42 on the manifold 10, the water temperature in the electric drive thermal management circuit can be detected in a timely manner, and the seven-way valve 20 or the three-way valve 30 can be controlled according to the detection results of the first water temperature sensor 41 and the second water temperature sensor 42, improving the control efficiency.

[0046] As Figure 3 shown, in this embodiment, the first interface 121, the fourth interface 124, the fifth interface 125, the sixth interface 126, the seventh interface 127, the eighth interface 128, the ninth interface 131, the tenth interface 132, and the eleventh interface 133 are located on the first side 101 of the manifold 10, and the second interface 122 and the third interface 123 are located on the second side 102 of the manifold 10. The first side 101 and the second side 102 are adjacently arranged. This arrangement makes the pipelines more concentrated, saves the layout space, and optimizes the in-vehicle layout.

[0047] At the same time, referring to Figure 4 and Figure 5 , in this embodiment, the seven-way valve 20 is fixed to the manifold 10 by fasteners. The first water temperature sensor 41 and the second water temperature sensor 42 are arranged on one side of the seven-way valve 20 close to the second side 102. The first water temperature sensor 41 is arranged close to the first side 101, and the second water temperature sensor 42 is arranged away from the first side 101. The battery cooling heat exchanger 60 is fixed on the side opposite to the second side 102. The three-way valve 30 and the water-water heat exchanger 50 are fixed between the seven-way valve 20 and the battery cooling heat exchanger 60 by fasteners. The three-way valve 30 is arranged close to the first side 101, and the water-water heat exchanger 50 is arranged away from the first side 101.

[0048] The positional relationships of the various components in the thermal management integrated valve and the arrangement manner of the various interfaces can be flexibly adjusted according to the settings of the various circuits in the thermal management system to meet the design requirements of pure electric charging vehicles, optimize the efficiency of the thermal management system, save the layout space, and reduce the complexity of pipeline layout.

[0049] The present application also provides a vehicle, including a battery thermal management circuit, an electric drive thermal management circuit, a heating circuit, and the thermal management integrated valve as described above. Both the battery thermal management circuit and the electric drive thermal management circuit are connected to the seven-way valve 20, and the heating circuit is connected to the three-way valve 30.

[0050] In the heat management integrated valve and vehicle of the present application, by integrally arranging the seven-way valve 20 and the three-way valve 30 on the manifold 10, the integrated arrangement of the seven-way valve 20 and the three-way valve 30 in the heat management system is realized, saving the layout space and reducing both the assembly difficulty and cost. At the same time, by arranging the coolant flow channel 11 in the manifold 10, the connection complexity of the cooling pipes in the heat management system is simplified, the pipeline layout is more concise and beautiful, and the risk of system leakage is reduced.

Although the present application has been disclosed above in a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art, without departing from the technical solution of the present application, can make some modifications or equivalents by using the above-disclosed technical content.
