All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] It should be noted that: similar reference numerals and letters denote similar items in the following accompanying drawings. Therefore, once an item is defined in one accompanying drawing, it does not need to be further defined and explained in subsequent accompanying drawings.

[0028] All the electrical components appearing in this text are electrically connected to the external main controller and the 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0029] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "inside", "outside", "upper", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use.

[0030] As Figures 1 to 5 shown, a highly heat-dissipating integrated busbar for energy storage batteries includes: a lower cover plate 1, an upper cover plate 101, a limiting plate 102, and a circuit board 104 are sequentially arranged outside the lower cover plate 1. A metal part 103 is arranged inside the limiting plate 102, and there are multiple metal parts 103; a cooling part 3 is arranged inside the upper cover plate 101 and is used for cooling the metal parts 103; a connection component 2 is arranged outside the cooling part 3 and is used for guiding the refrigerant; a limiting component 4 is arranged inside the connection component 2 and is used for connecting the connection component 2 and the cooling part 3. During use, the positions of the lower cover plate 1, the upper cover plate 101, the limiting plate 102, the circuit board 104, and the metal parts 103 are fixed. During use, through the cooperation of the connection component 2 and the limiting component 4, the refrigerant is introduced into the cooling part 3, so that the cooling part 3 dissipates heat from the metal parts 103 and the circuit board 104, and avoids waste of electricity caused by excessive temperatures of the metal parts 103 and the circuit board 104 during use.

[0031] As Figures 1 to 5 shown, the cooling part 3 includes a cooling plate 301. An inlet pipe 303 and an outlet pipe 304 are respectively arranged on one side of the cooling plate 301. A flow channel 302 is arranged inside the cooling plate 301, and both ends of the flow channel 302 are respectively communicated with the inlet pipe 303 and the outlet pipe 304. The cooling plate 301 has good thermal conductivity to ensure that heat can be fully exchanged during use. The inner wall of the flow channel 302 is granular, so as to increase the contact area with the refrigerant. The flow channel 302 guides the refrigerant and at the same time increases the flow time of the refrigerant inside the cooling plate 301 to ensure that the refrigerant can fully absorb heat during use. The inlet pipe 303 and the outlet pipe 304 control the flow direction of the refrigerant to prevent the cooling effect from being reduced due to the contact between high-temperature refrigerant and low-temperature refrigerant.

[0032] As Figures 1 to 5 shown, a heat-conducting pad 105 is arranged outside the cooling plate 301, and the heat-conducting pad 105 is attached to the metal part 103. The heat-conducting pad 105 is made of a heat-conducting material. The heat-conducting pad 105 fills the gaps between the cooling plate 301, the circuit board 104, and the metal part 103 to prevent the cooling effect from being reduced due to the existence of gaps between the cooling plate 301, the circuit board 104, and the metal part 103.

[0033] AsFigures 1 to 5 As shown, the limit assembly 4 includes a mounting block 401, a connecting plate 404 and a threaded rod 403. The mounting block 401 is provided with a connecting pipe 406 at one end relative to the cooling plate 301. The connecting pipes 406 are multiple, and the connecting pipes 406 correspond to the liquid outlet pipe 304 and the liquid inlet pipe 303. The connecting pipe 406 is connected to the cooling plate 301. A sliding groove 402 is provided on the outer side of the mounting block 401. The sliding groove 402 is multiple. The threaded rod 403 rotates inside the mounting block 401. The connecting plate 404 is connected to the threaded rod 403, and the connecting plate 404 is arranged inside the mounting block 401. A connecting block 405 is provided inside the sliding groove 402. Block 405 moves relative to the mounting block 401, and the connecting block 405 is threadedly connected to the threaded rod 403, and the connecting plate 404 fixes the position of the threaded rod 403 to prevent the threaded rod 403 from being displaced relative to the mounting block 401 during use. The mounting block 401 cooperates with the connecting pipe 406 to connect the liquid inlet pipe 303 and the liquid outlet pipe 304, so that the refrigerant can enter the flow channel 302 for internal circulation under the guidance of the mounting block 401. Left-handed threads and right-handed threads are respectively provided at both ends of the threaded rod 403, so that during the rotation of the threaded rod 403, the connecting blocks 405 on both sides are driven to move toward or in the opposite direction inside the sliding groove 402.

[0034] like Figures 1 to 5 As shown, the connection assembly 2 includes a fixing block 201, a connecting sleeve 202 and a fixing tube 204, the connecting sleeve 202 and the fixing tube 204 are respectively arranged at both ends of the fixing block 201, and the fixing block 201 is connected to the fixing tube 204, the connecting sleeve 202 is sleeved on the outside of the mounting block 401, and a limiting hole 205 is provided inside the connecting sleeve 202, the limiting hole 205 passes through the connecting sleeve 202, and the limiting hole 205 is adapted to the connecting block 405, and the connecting sleeve 202 is plugged in and out, so that the cooling plate 301 or the circuit board can be connected. 104, a single upper cover plate 101 can be replaced, thereby reducing the cost of maintenance. When in use, firstly, the connecting sleeve 202 is sleeved on the outside of the mounting block 401. After the sleeve is completed, the threaded rod 403 is rotated. During the rotation of the threaded rod 403, the connecting block 405 is driven to move in the opposite direction, so that the connecting block 405 is inserted into the limiting hole 205, thereby quickly fixing the position of the connecting sleeve 202, so that the refrigerant can enter the inside of the mounting block 401 under the guidance of the fixed tube 204 and the fixed block 201.

[0035] like Figures 1 to 5 As shown, a sealing gasket 203 is provided at the end of the fixed block 201 relative to the mounting block 401. The sealing gasket 203 fills the gap between the fixed block 201 and the mounting block 401 to prevent the refrigerant from leaking from the gap between the fixed block 201 and the mounting block 401 during use, thereby ensuring stability during use.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model.
