With the continuous expansion of the application field of battery device, the market demand is also increasing. The energy storage device with multiple battery devices has been widely applied due to its large amount of electric energy storage.

[0080] In the related art, the heat exchange system includes multiple pipelines and multiple functional components, and the multiple pipelines and the multiple functional components are dispersedly arranged, resulting in low space utilization rate in the heat exchange system.

[0081] In the present application, the cooling liquid assembly includes an integrated seat and multiple functional components, and the integrated seat is provided with multiple internal flow channels. At least two of the multiple functional components are respectively mounted on the integrated seat, and all the functional components mounted on the integrated seat are sequentially and communicatively arranged through the multiple internal flow channels. Mounting at least two of the multiple functional components on the integrated seat enables the components to be integrated, thereby reducing the degree of dispersion of the components, reducing the space occupied by the components in the heat exchange system, and effectively improving the space utilization rate of the heat exchange system.

[0082] In some embodiments of the present application, as shown in FIGS. 1-15, a heat exchange system 30 is provided, which includes a cooling liquid assembly 32. The cooling liquid assembly 32 includes an integrated seat 322 and multiple functional components 321. The integrated seat 322 is provided with multiple internal flow channels. At least two of the multiple functional components 321 are respectively mounted on the integrated seat 322. All the functional components mounted on the integrated seat 322 are sequentially and communicatively arranged through the multiple internal flow channels.

[0083] In the present application, the cooling liquid assembly 32 can form a cooling liquid circulation flow path, and the cooling liquid circulates in the cooling liquid circulation flow path. The functional component refers to a component that realizes a specific function in the cooling liquid circulation flow path, such as a water pump 324, a heating element 329 or a first heat exchange element 325, etc. Under the drive of the water pump 324, the cooling liquid can circulate in the cooling liquid circulation flow path. When the cooling liquid passes through the heating element 329, the heating element 329 can heat the cooling liquid to increase the temperature of the cooling liquid, thereby meeting the heat exchange demand of the heat exchange system 30. When the cooling liquid flows to the first heat exchange element 325, the cooling liquid can exchange heat with other components through the first heat exchange element 325, so that the temperature of the other components meets the heat exchange demand.

[0084] In addition, the integrated seat 322 serves as a mounting carrier of the functional components, and when the functional components are mounted on the integrated seat 322, the connection between the functional components and the integrated seat 322 includes welding, bonding, clamping, or connection through a connecting piece (such as a bolt or a screw, etc.), and the like.

[0085] In addition, the internal flow channel is a flow channel structure formed inside the integrated seat 322, that is, an integrated structure with the integrated seat 322, and when the integrated seat 322 is processed, the internal flow channel is processed synchronously.

[0086] In this application, the number of internal flow channels refers to one, two, three, four, five, or six, etc. In addition, the shape of the flow cross section of the internal flow channel includes but is not limited to a rectangle, a circle, an ellipse, a triangle, a rhombus, a trapezoid, a pentagon, or a hexagon, etc. In addition, the internal flow channel can be a straight line type flow channel or a broken line type flow channel, and when the internal flow channel is a broken line type flow channel, a circular arc transition structure is formed at the corner position of the flow channel to reduce the flow resistance of the cooling liquid at the corner position, thereby improving the flow rate of the cooling liquid, so that the heat exchange efficiency of the heat exchange system 30 can be improved.

[0087] Specifically, at least two of the plurality of functional components 321 are mounted on the integrated seat 322, so that the components can be integrated, thereby reducing the degree of dispersion of the components and reducing the space occupied by the components in the heat exchange system 30, thereby effectively improving the space utilization of the heat exchange system 30.

[0088] In addition, the connecting pipeline between the at least two functional components mounted on the integrated seat 322 can be shortened, thereby reducing the flow path of the cooling liquid, reducing the flow resistance of the cooling liquid, thereby improving the flow rate of the cooling liquid, and effectively improving the heat exchange efficiency of the heat exchange system 30.

[0089] In addition, the heat exchange system 30 further includes a fan, and the plurality of functional components 321 further include a radiator, which constitutes part of the cooling liquid circulation flow path. When the cooling liquid flows through the radiator, the cooling liquid exchanges heat with the air through the radiator. The fan is arranged adjacent to the radiator, and the fan operates to improve the flow rate of the air and improve the heat exchange efficiency of the cooling liquid and the air. When at least two functional components are mounted on the integrated seat 322, the dispersion of the components can be reduced, so that the back pressure of the fan can be reduced, thereby reducing the speed of the fan, and thereby reducing the noise when the heat exchange system 30 operates.

[0090] It should be noted that in this application, the functional components mounted on the integrated seat 322 can be two, three, four, five, six, seven, or eight, etc.

[0091] In addition, communication is required between the functional components mounted on the integrated seat 322, and the structure for communicating the two functional components includes a pipeline (external pipeline such as a rubber tube, etc.) or an internal flow channel of the integrated seat 322.

[0092] In addition, the cooling liquid can be a molten metal liquid, and the cooling liquid can be a glycol aqueous solution, etc. The type of the cooling liquid is not limited in the embodiments of the present application.
