[0090] Currently, from the perspective of the development of the market situation, the application of battery devices is becoming more and more extensive. Battery devices are not only applied to energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied to electric transportation means such as electric bicycles, electric motorcycles, and electric vehicles, as well as multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of battery devices, the market demand is also continuously increasing. Energy storage devices with multiple battery devices have been widely applied due to their advantages such as large electrical energy storage capacity.

[0091] In the related art, the heat exchange system includes multiple pipelines and multiple functional components. The multiple pipelines and multiple functional components are dispersedly arranged, resulting in low space utilization rate in the heat exchange system.

[0092] In the present application, the heat exchange system includes a coolant assembly. The coolant assembly includes an integrated seat, a water pump, a heating element, and a first heat exchange element. At least two of the water pump, the heating element, and the first heat exchange element are installed on the integrated seat, and the water pump, the first heat exchange element, and the heating element are sequentially connected and arranged through the integrated seat. Installing at least two of the water pump, the heating element, and the first heat exchange element on the integrated seat can reduce the degree of component dispersion, thereby reducing the space occupied in the heat exchange system, and further effectively improving the space utilization rate of the heat exchange system.

[0093] In some embodiments of the present application, such as Figures 1 to 7As shown, a heat exchange system 30 is proposed. The heat exchange system 30 includes a coolant assembly 31. The coolant assembly 31 includes an integrated base 311, a water pump 312, a heating element 314, and a first heat exchanger 313. At least two of the water pump 312, the heating element 314, and the first heat exchanger 313 are mounted on the integrated base 311, and the water pump 312, the first heat exchanger 313, and the heating element 314 are sequentially connected through the integrated base 311.

[0094] In this application, the coolant assembly 31 can form a coolant circulation flow path, and the coolant circulates in the coolant circulation flow path. The water pump 312, the heating element 314, and the first heat exchanger 313 are all components in the coolant circulation flow path. Driven by the water pump 312, the coolant can circulate in the coolant circulation flow path. When the coolant passes through the heating element 314, the heating element 314 can heat the coolant to increase the temperature of the coolant, so as to meet the heat exchange requirements of the heat exchange system 30. When the coolant flows to the first heat exchanger 313, the coolant can exchange heat with other components through the first heat exchanger 313 to make the temperature of other components reach the heat exchange requirements.

[0095] In addition, the integrated base 311 serves as an installation carrier. Among them, when at least two of the water pump 312, the heating element 314, and the first heat exchanger 313 are mounted on the integrated base 311, the connection method between them and the integrated base 311 includes welding, bonding, clamping, or connection through a connecting member (such as a bolt or a screw, etc.).

[0096] Specifically, at least two of the water pump 312, the heating element 314, and the first heat exchanger 313 are mounted on the integrated base 311, so as to reduce the degree of component dispersion, thereby reducing the space occupied in the heat exchange system 30, and further effectively improving the space utilization rate of the heat exchange system 30.

[0097] In addition, at least two of the water pump 312, the heating element 314, and the first heat exchanger 313 are mounted on the integrated base 311. Two components on the integrated base 311 that communicate with each other are connected through the integrated base 311 without using a connecting pipeline, so as to shorten the connection path between the two components, thereby reducing the flow path of the coolant, reducing the flow resistance of the coolant, and further increasing the flow rate of the coolant, effectively improving the heat exchange efficiency of the heat exchange system 30.

[0098] In addition, the heat exchange system 30 further includes a fan and a radiator. The radiator forms a part of the coolant circulation flow path. When the coolant flows through the radiator, heat exchange occurs between the coolant and the air through the radiator. The fan is disposed adjacent to the radiator, and the fan operates to increase the air flow rate and improve the heat exchange efficiency between the coolant and the air. When at least two of the water pump 312, the heating element 314, and the first heat exchange element 313 are mounted on the integrated base 311, the dispersion of components can be reduced, the back pressure of the fan can be lowered, thereby reducing the rotational speed of the fan, and further reducing the noise during the operation of the heat exchange system 30.

[0099] It should be noted that in the present application, the water pump 312, the heating element 314, and the first heat exchange element 313 are all mounted on the integrated base 311. In addition, other functional components can also be mounted on the integrated base 311, where the number of other functional components includes, but is not limited to, one, two, three, four, five, six, seven, eight, etc.

[0100] In addition, the components mounted on the integrated base 311 need to be connected. The structure for connecting two functional components is an internal flow path provided in the integrated base 311.

[0101] In addition, the coolant can be molten metal liquid, and the coolant can be ethylene glycol aqueous solution, etc. The present application embodiment does not limit the type of the coolant.

[0102] In some embodiments of the present application, as Figure 4 shown, the integrated base 311 includes a first flow path 31125 and a second flow path 31133. The water pump 312, the first heat exchange element 313, and the heating element 314 are respectively connected to the integrated base 311. The water pump 312 is connected to the first heat exchange element 313 through the first flow path 31125, and the first heat exchange element 313 is connected to the heating element 314 through the second flow path 31133.

[0103] In the present application, both the first flow path 31125 and the second flow path 31133 are structures formed inside the integrated base 311, where the first flow path 31125 and the second flow path 31133 are isolated from each other, that is, the first flow path 31125 and the second flow path 31133 are not connected to each other.

[0104] Specifically, the water pump 312, the first heat exchange element 313, and the heating element 314 are respectively mounted on the integrated base 311, so as to further integrate the functional components in the heat exchange system 30, further reduce the dispersion degree of the functional components, and further reduce the space occupied by the functional components in the heat exchange system 30, thereby further improving the space utilization rate of the heat exchange system 30.

[0105] In addition, a water pump 312, a first heat exchanger 313, and a heating element 314 are respectively installed on an integrated base 311. The water pump 312 is communicated with a first flow channel 31125 and is communicated with the first heat exchanger 313 through the first flow channel 31125. The heating element 314 is communicated with a second flow channel 31133 and is communicated with the first heat exchanger 313 through the second flow channel 31133. The first flow channel 31125 and the second flow channel 31133 are arranged on the integrated base 311, and the water pump 312, the first heat exchanger 313, and the heating element 314 are sequentially communicated through the first flow channel 31125 and the second flow channel 31133, so that the length of the pipeline in the heat exchange system 30 can be reduced, the flow resistance of the coolant is reduced, and the heat exchange efficiency can be improved.

[0106] In some embodiments of the present application, as Figure 5 and Figure 7 shown, the first heat exchanger 313 includes a first channel 3135. The integrated base 311 includes a connected first body 3111 and a second body 3112. The first body 3111 and the second body 3112 enclose to form a first flow channel 31125. The first heat exchanger 313 is installed on the first body 3111, the water pump 312 is installed on the second body 3112, and the first flow channel 31125 and the water pump 312 are respectively communicated with the first channel 3135.

[0107] Specifically, the integrated base 311 includes a first body 3111 and a second body 3112. The first body 3111 and the second body 3112 are connected to each other. The first body 3111 and the second body 3112 can be an integral structure or a split structure.

[0108] When the first body 3111 and the second body 3112 are of an integral structure, the first body 3111 and the second body 3112 are integrally formed by casting or other methods.

[0109] When the first body 3111 and the second body 3112 are of a split structure, the connection manner between the first body 3111 and the second body 3112 includes but is not limited to welding, bonding, clamping, or connection through a connecting member (such as a screw, etc.).

[0110] Installing the first heat exchanger 313 on the first body 3111 and installing the water pump 312 on the second body 3112 can make there be a gap between the first heat exchanger 313 and the water pump 312, which is convenient for assembly and effectively improves the assembly efficiency.

[0111] Specifically, the first flow channel 31125 is formed by enclosing, which can reduce the manufacturing difficulty of the integrated base 311 and effectively improve the processing convenience.

[0112] In the present application, the first heat exchanger 313 is communicatively connected to the first flow channel 31125. Among them, there are various ways of communication between the first heat exchanger 313 and the first flow channel 31125:

[0113] In some embodiments of the present application, a first communication port is provided on the first heat exchanger 313, and a second communication port is provided on the first body 3111 (the second communication port is communicatively connected to the first flow channel 31125). The first heat exchanger 313 is fixed on the first body 3111, and the first communication port and the second communication port are coaxially docked, and sealed at the docking position, thereby realizing the communicative connection between the first heat exchanger 313 and the first flow channel 31125.

The first heat exchanger 313 is fixed on the first body 3111, and the first plug is inserted into the first jack, and sealed at the insertion position (for example, a sealing structure such as an O-ring is provided), thereby realizing the communicative connection between the first heat exchanger 313 and the first flow channel 31125.

[0115] In some embodiments of the present application, as Figure 4 shown, the first heat exchanger 313 further includes a first plug connector 3131. The first plug connector 3131 is communicatively connected to the first channel 3135. A first insertion hole 31112 is formed on the first body 3111.

[0116] Specifically, the first plug connector 3131 is provided on the first heat exchanger 313 and protrudes from the surface of the first heat exchanger 313. The first plug connector 3131 is communicatively connected to the first channel 3135 of the first heat exchanger 313. The first insertion hole 31112 is formed on the first body 3111 and is communicatively connected to the first flow channel 31125 of the integrated seat 311. When the first heat exchanger 313 is installed and fixed on the first body 3111 of the integrated seat 311, the first plug connector 3131 of the first heat exchanger 313 is inserted into the first insertion hole 31112, and sealed at the insertion position of the first plug connector 3131 and the first insertion hole 31112 (for example, a sealing structure such as an O-ring is provided).

[0117] The first heat exchanger 313 realizes the communication between the first channel 3135 and the first channel 3135 through the plugging fit between the first plug connector 3131 and the first jack.

[0118] In the present application, the water pump 312 is communicatively connected to the second flow channel 31133. There are various ways of connection between the water pump 312 and the second flow channel 31133:

[0119] In some embodiments of the present application, the water pump 312 includes an inlet and an outlet. The water pump 312 is installed on the second body 3112 (the installation methods include but are not limited to welding, bonding, clamping or connection by connecting parts such as screws). The outlet of the water pump 312 is communicatively connected to the second flow channel 31133. The connection method between the outlet and the second flow channel 31133 can be: a first interface is provided on the first body 3111 (the first interface is communicatively connected to the second flow channel 31133), the water pump 312 is fixed on the first body 3111, and the first interface is coaxially docked with the outlet, and sealing is performed at the docking position, thereby realizing the communicative connection between the water pump 312 and the second flow channel 31133. Or, a second interface is provided on the first body 3111, the water pump 312 has an outlet joint, the outlet is provided on the outlet joint, the water pump 312 is fixed on the first body 3111, and the outlet joint is inserted into the first interface, and sealing is performed at the insertion position (for example, a sealing structure such as a sealing ring is provided), thereby realizing the communicative connection between the water pump 312 and the second flow channel 31133.

[0120] In some embodiments of the present application, as Figure 4 and Figure 5 shown, the second body 3112 includes a liquid inlet joint 31123 and a receiving cavity 31126. The receiving cavity 31126 is communicatively connected to the liquid inlet joint 31123 and the first flow channel 31125 respectively. The water pump 312 includes an impeller mechanism 3121. The impeller mechanism 3121 includes a liquid inlet 3122 and a liquid outlet 3123. The impeller mechanism 3121 is installed in the receiving cavity 31126. The liquid outlet 3123 is communicatively connected to the first flow channel 31125, and the liquid inlet 3122 is communicatively connected to the liquid inlet joint 31123.

[0121] It should be understood that the water pump 312 includes a motor. The impeller mechanism 3121 of the water pump 312 includes a pump cavity and an impeller. The impeller is rotatably arranged in the pump cavity. Both the liquid inlet 3122 and the liquid outlet 3123 are provided on the pump cavity. Among them, the liquid inlet 3122 is located at the axial end of the impeller, the liquid outlet 3123 is located on the radial outside of the impeller. The motor is in transmission connection with the impeller. The motor drives the impeller to rotate. The impeller is of a centrifugal structure. When the impeller rotates, it can suck the coolant from the liquid inlet 3122 axially and discharge it circumferentially, and then output it through the liquid outlet 3123.

[0122] Specifically, a receiving cavity 31126 is formed on the second body 3112. The receiving cavity 31126 has an installation opening. The impeller mechanism 3121 of the water pump 312 is inserted into the receiving cavity 31126 of the second body 3112 through the installation opening, and the liquid inlet 3122 of the water pump 312 is communicated with the liquid inlet joint 31123, so as to effectively meet the installation of the water pump 312, enabling the water pump 312 to drive the coolant to enter the first flow channel 31125 from the liquid inlet joint 31123, and further providing power for the circulation of the coolant.

[0123] In addition, the impeller mechanism 3121 of the water pump 312 is inserted into the receiving cavity 31126, so that the water pump 312 and the second body 3112 are embeddedly installed, further making the overall structure more compact, achieving the purpose of further reducing the overall volume, and further reducing the space occupied by the heat exchange system 30, so as to effectively improve the space utilization rate of the heat exchange system 30.

[0124] In some embodiments of the present application, the liquid inlet joint 31123 and the impeller mechanism 3121 are coaxially arranged.

[0125] Specifically, the water pump 312 is a centrifugal water pump 312. The liquid inlet 3122 and the liquid outlet 3123 are respectively formed on the pump cavity. The liquid inlet 3122 is formed in the axial direction of the impeller, and the liquid outlet 3123 is located radially outside the impeller. The liquid inlet joint 31123 and the impeller are arranged coaxially, so as to be adapted to the structure of the water pump 312, thereby improving the installation convenience of the water pump 312, and also facilitating the coolant to enter the liquid inlet 3122 through the liquid inlet joint 31123.

[0126] It should be noted that a connection joint protrudes on the pump cavity of the water pump 312, and the liquid inlet 3122 is formed on the connection joint. After the water pump 312 is installed in place in the receiving cavity 31126, the connection joint is inserted into the inside of the liquid inlet joint 31123, and a sealing is provided between the inner wall of the liquid inlet joint 31123 and the outer wall of the connection joint, so that the coolant can enter the connection joint through the liquid inlet joint 31123, thereby realizing the liquid inlet of the water pump 312.

[0127] Figures 4 to 6 As shown, the extending direction of the first flow channel 31125 intersects with the rotation axis of the impeller mechanism 3121, and there is a spacing distance between the communication position of the first flow channel 31125 and the receiving cavity 31126 and the rotation axis.

[0128] ​Specifically, the water pump 312 is a centrifugal water pump 312. The liquid inlet 3122 and the liquid outlet 3123 are respectively opened on the pump chamber. The liquid inlet 3122 is opened in the axial direction of the impeller, and the liquid outlet 3123 is located radially outside the impeller in the impeller mechanism 3121. When the impeller rotates, the coolant is sucked in through the axial direction of the impeller and then thrown out through the radial direction of the impeller. The extending direction of the first flow channel 31125 intersects with the rotation axis of the impeller mechanism 3121. There is a spacing distance between the connecting position of the first flow channel 31125 and the receiving cavity 31126 and the rotation axis, so that it can be adapted to the impeller mechanism 3121 of the water pump 312, thereby improving the efficiency of the water pump 312 in pumping the coolant.

[0129] In the present application, the spacing distance between the connecting position of the first flow channel 31125 and the receiving cavity 31126 and the rotation axis is equal to the radius of the impeller. At this time, the first flow channel 31125 is tangent to the receiving cavity 31126. Setting the first flow channel 31125 to be tangent to the receiving cavity 31126 is more conducive to the discharge of the coolant from the water pump 312, thereby improving the smoothness of the outflow of the coolant.

[0130] In some embodiments of the present application, as Figure 4 shown, the second body 3112 includes a first part 31121 and a second part 31122. The first part 31121 has a first cavity. Along the axial direction of the impeller, the first cavity includes a first opening and a second opening arranged oppositely. The first part 31121 is connected to the first body 3111. Part of the first opening is closed by the first body 3111. One end of the water pump 312 having the impeller is inserted into the first cavity and closes the other part of the first opening. The liquid inlet joint 31123 is arranged on the second part 31122. The second part 31122 is connected to the first part 31121 and closes the second opening. The second part 31122 and the first part 31121 enclose the receiving cavity 31126.

[0131] Specifically, the first cavity is opened on the first part 31121 of the second body 3112, and the first cavity is in a b-shaped structure. After the first part 31121 is connected to the first body 3111, the first body 3111 closes part of the first opening (the upper half of the b-shaped structure (the part outside the closed part)), and the second part 31122 completely closes the second opening. Among them, in the b-shaped structure, the lower half (the closed part) forms the receiving cavity 31126, and the upper half forms the first flow channel 31125 (the part outside the closed part).

[0132] Specifically, the second body 3112 is provided as a split structure so that a first cavity can be machined on the first part 31121, and a first runner 31125 and a receiving cavity 31126 are formed by enclosing with the first body 3111 and the second part 31122, thereby reducing the manufacturing difficulty and effectively improving the processing convenience.

[0133] It should be noted that the connection between the first part 31121 and the first body 3111 can be an integral structure or a split structure. When the first part 31121 and the first body 3111 are in a split structure, the connection methods between the first part 31121 and the first body 3111 include but are not limited to welding, bonding, gluing or connection via a connecting member (such as a screw, etc.).

[0134] The connection methods between the second part 31122 and the first part 31121 include but are not limited to welding, bonding, gluing or connection via a connecting member (such as a screw, etc.).

At the same time, a sealing structure (such as a sealing ring or sealant, etc.) is provided at the joint position of the first part 31121 and the second part 31122 to reduce the occurrence of coolant leakage at the joint position of the first part 31121 and the second part 31122.

[0136] In addition, a plurality of rib plates 31124 are provided on the second part 31122, and the plurality of rib plates can increase the structural strength of the second part 31122.

[0137] In some embodiments of the present application, as Figures 4 to 6 shown, the integrated base 311 further includes a third body 3113. The third body 3113 and the first body 3111 enclose to form a second runner 31133. The heating element 314 is installed on the third body 3113, and the second runner 31133 and the heating element 314 are respectively communicated with the first channel 3135.

The second body 3112 and the third body 3113 are respectively connected to the first body 3111. Among them, the connection between the third body 3113 and the first body 3111 can be an integral structure or a split structure.

[0140] When the first body 3111 and the third body 3113 are of a split structure, the connection methods between the first body 3111 and the third body 3113 include but are not limited to welding, bonding, clamping or connection via a connecting member (such as a screw, etc.).

[0141] Install the first heat exchanger 313 on the first body 3111 and install the heating element 314 on the third body 3113, so that there is a gap between the first heat exchanger 313 and the heating element 314, which is convenient for assembly and effectively improves the assembly efficiency.

[0142] Specifically, set the third body 3113, and form the second flow channel 31133 by enclosing the third body 3113 and the first body 3111, which is convenient for processing the third flow channel, improves the processing convenience, and effectively improves the processing efficiency.

[0143] In this application, the first heat exchanger 313 is connected and communicated with the second flow channel 31133. Among them, there are various ways of communication between the first heat exchanger 313 and the second flow channel 31133:

[0145] In some embodiments of this application, a second jack is provided on the first heat exchanger 313, and a second plug is provided on the first body 3111 (the second plug is connected and communicated with the second flow channel 31133). Fix the first heat exchanger 313 on the first body 3111, and make the second plug inserted into the second jack, and seal at the insertion position (such as setting a sealing structure such as a sealing ring, etc.), so as to realize the connection and communication between the first heat exchanger 313 and the first flow channel 31125.

[0146] In some embodiments of this application, such as Figure 4As shown, the first heat exchanger 313 further includes a second socket 3132. The second socket 3132 is in communication with the first channel 3135. A second socket hole 31111 is formed on the first body 3111. The second socket 3132 is inserted into the second socket hole 31111 in a plug-in fit and is in communication with the second flow channel 31133.

[0147] Specifically, the second socket 3132 is disposed on the first heat exchanger 313 and protrudes from the surface of the first heat exchanger 313.

The plug-in fit method is convenient for assembly, thus effectively improving the assembly efficiency.

[0149] In some embodiments of the present application, as Figure 4 shown, the third body 3113 includes a first structural part 31131 and a second structural part 31132.

[0150] Specifically, the second cavity is formed on the first structural part 31131 of the third body 3113, and the first cavity is a U-shaped structure. After the first body 3111 is connected to the first structural part 31131, the first body 3111 closes the first port, and the second part 31122 completely closes the second port, thereby enclosing the second flow channel 31133.

[0151] Specifically, the third body 3113 is provided with a split structure, so as to process the second cavity on the first structural part 31131 and form the second flow channel 31133 through the enclosure of the first body 3111 and the second structural part 31132, thereby reducing the manufacturing difficulty and effectively improving the processing convenience.

[0152] It should be noted that the first structural part 31131 and the first body 3111 can be an integral structure or a split structure.

[0155] In the present application, the heating element 314 is communicatively connected to the second flow channel 31133. Among them, there are various ways of communication between the heating element 314 and the second flow channel 31133:

[0156] In some embodiments of the present application, a first connection port is provided on the heating element 314, and a second connection port (the second connection port is communicatively connected to the second flow channel 31133) is provided on the third body 3113. The heating element 314 is fixed on the third body 3113, and the first connection port and the second connection port are coaxially docked, and sealed at the docking position, thereby realizing the communicative connection between the heating element 314 and the second flow channel 31133.

[0158] In some embodiments of the present application, as Figures 4 to 6As shown, a third insertion hole 31134 is formed in one of the first structural part 31131, the second structural part 31132, and the first body 3111.

Among them, the third insertion joint 3141 is in plug-in fit with the third insertion hole 31134, and a sealing structure (such as a sealing ring) is provided at the plug-in position.

[0160] Through the plug-in fit between the third insertion joint 3141 of the heating element 314 and the third insertion hole, the communication between the heating element 314 and the second channel 3136 is realized. The plug-in fit method is convenient for assembly, thus effectively improving the assembly efficiency.

[0161] It should be understood that in the present application, a coolant channel is provided in the heating element 314. The third insertion joint 3141 and the sixth insertion joint 3142 are respectively in communication with the coolant flow channel. When the coolant flows through the coolant flow channel, the internal heating component of the heating element 314 heats the coolant to increase the temperature of the coolant.

[0162] In some embodiments of the present application, the coolant assembly 31 further includes a second heat exchanger 315. The second heat exchanger 315 is in communication with the first channel 3135 to form a coolant circuit. The second heat exchanger 315 is used to exchange heat with the battery device 20 of the energy storage device 100.

[0163] The second heat exchanger 315 is provided so that the coolant in the first channel 3135 circulates to the position of the second heat exchanger 315 and exchanges heat with the battery device 20 through the second heat exchanger 315, so that the battery device 20 can be maintained within a better temperature range, and thus the battery device 20 can fully exert its performance.

[0164] It should be noted that the second heat exchanger 315 is a plate heat exchanger or a fin heat exchanger, etc.

[0165] In some embodiments of the present application, as Figure 7 shown, the first heat exchanger 313 further includes a second channel 3136. The second channel 3136 is isolated from the first channel 3135, and the second channel 3136 and the first channel 3135 are heat-exchanged with each other. The heat exchange system 30 further includes a refrigerant assembly 32. The refrigerant assembly 32 includes a third heat exchanger 321. The third heat exchanger 321 is in communication with the second channel 3136 to form a refrigerant circuit. The third heat exchanger 321 is used to exchange heat with air.

[0166] Specifically, a second channel 3136 is provided inside the first heat exchanger 313, enabling the coolant and the refrigerant to exchange heat inside the first heat exchanger 313, reducing the number of components, and further improving the space utilization rate of the heat exchange system 30.

The throttling element 323 (such as a capillary tube or a throttle valve, etc.), the third heat exchanger 321 (such as a fin radiator or a plate heat exchanger, etc.) and the compressor 322 are respectively connected in series between the inlet and the outlet of the second channel 3136, thereby forming a refrigerant circuit for the refrigerant to circulate.

[0169] In the coolant assembly 31, a water pump 312, a second heat exchanger 315, and a heating element 314 are respectively connected in series between the inlet and the outlet of the first channel 3135, thereby forming a coolant circuit for the coolant to circulate.

[0170] When heat exchanging the battery device 20, both the refrigerant assembly 32 and the coolant assembly 31 operate. The refrigerant circulates in the refrigerant circuit, and the coolant circulates in the coolant circuit. The refrigerant circulating to the second flow path exchanges heat with the coolant circulating to the first flow path. The coolant after heat exchange enters the second heat exchanger 315 and exchanges heat with the battery device 20 through the second heat exchanger 315. The coolant after exchanging heat with the battery device 20 circulates back to the first flow path again to exchange heat with the refrigerant again; the refrigerant after exchanging heat with the coolant circulates to the third heat exchanger 321 to exchange heat with the outside air, and the refrigerant after heat exchange through the third heat exchanger 321 circulates back to the second flow path again to exchange heat with the coolant again.

[0171] In the structure shown in the drawings of the present application, as Figures 3 to 6 shown, the first body 3111 is a plate-like member and is provided with a plurality of first connection holes 31115.

[0180] Specifically, by setting the installation position of the integrated base 311, the integrated base 311 is arranged close to the first side wall 341 in the first direction a, and by installing at least two of the water pump 312, the first heat exchanger 313, and the heating element 314 on the integrated base 311, the structure of the coolant assembly 31 is made more compact, reducing the occupation of the internal space of the housing 34, thereby increasing the air resistance of the air flow inside the housing 34.

[0181] In some embodiments of the present application, the integrated base 311 is an injection molded part or a die cast part.

[0182] Specifically, the integrated base 311 is set, thereby improving the convenience of processing and effectively enhancing the consistency of the performance of the integrated base 311.

[0183] As Figures 1 to 6 shown, a second aspect of the present application proposes an energy storage device 100, which includes a box body 10, a battery device 20, and a heat exchange system 30 as described above. The battery device 20 is arranged inside the box body 10. The heat exchange system 30 includes a refrigerant assembly 32 and a coolant assembly 31. The coolant assembly 31 includes a first heat exchanger 313 and a second heat exchanger 315. The first heat exchanger 313 includes a non-communicating first channel 3135 and a second channel 3136, and the first channel 3135 and the second channel 3136 are arranged to exchange heat with each other. The second heat exchanger 315 is connected to the first channel 3135 to form a coolant circuit, and the second heat exchanger 315 is used to exchange heat for the battery device 20 of the energy storage device 100. The refrigerant assembly 32 includes a third heat exchanger 321.

The cooled coolant enters the first chamber 101 under the drive of the water pump 312 and exchanges heat with the battery device 20. After heat exchange, the temperature of the coolant rises and it returns to the first heat exchange element 313 to exchange heat with the refrigerant again.

[0196] As an example, the battery cell assembly can also be accommodated in the housing by directly fixing a plurality of battery cells to the housing.

[0197] As an example, the housing can include a first part and a second part. The first part and the second part are snapped together so that a closed space is formed inside the housing to accommodate the battery cell assembly.

[0198] As an example, the housing can include a top cover, a frame, and a bottom plate. The top cover and the bottom plate are respectively connected to the frame so that a closed space is formed inside the housing to accommodate the battery cell assembly.

[0199] In some embodiments, when the battery device is used in a vehicle, the housing can be a part of the chassis structure of the vehicle. For example, a part of the housing can become at least a part of the floor of the vehicle, or a part of the housing can become at least a part of the cross beam and longitudinal beam of the vehicle.

[0200] In some embodiments, when the number of battery devices 20 is multiple, the multiple battery devices 20 include two or more battery devices 20.

In the present application, a bracket is provided inside the first chamber 101, and the battery device 20 is arranged on the bracket so that the battery devices 20 are arranged in a rectangular array in the first chamber 101, so as to facilitate accommodating a larger number of battery devices 20 in the first chamber 101, thereby improving the energy density of the energy storage device 100.
