Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an output electrode base and an output electrode assembly. Background Technology

[0002] In existing high-power electrical equipment, the output busbar and adapter busbar are typically secured to the output terminal base using mechanical fastening (such as screw connections or crimping) or welding methods. This is intended to maintain their installation accuracy within the equipment and prevent component displacement or connection failure due to mechanical vibration, external impact, or thermal cycling. However, due to the high contact resistance at the interface between the busbar and the base, localized high temperatures can easily occur in the contact area during long-term high-current operation, leading to melting and ablation of the conductor material. This thermal failure not only causes irreversible damage to the electrical connections but can also trigger serious faults such as short circuits and open circuits, significantly reducing system reliability and service life.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1-5 This invention describes the output electrode base and output electrode assembly.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of this utility model, the output electrode base 10 includes: a base plate 11, an inlet pipe 20, and an outlet pipe 30. The base plate 11 is provided with a connection hole 113 for connecting the output electrode busbar 60 and the adapter copper busbar 70. A flow channel 111 is provided inside the base plate 11, and the flow channel 111 is disposed adjacent to the connection hole 113. The inlet pipe 20 and the outlet pipe 30 are respectively connected to the two ends of the flow channel 111.

[0026] Specifically, the output bus 60 and the adapter copper bus 70 are connected to the base plate 11 of the output base 10 via fasteners. Due to the high contact resistance at the interface between the output bus 60 and the base plate 11, localized high temperatures are prone to occur in the contact area during long-term high-current operation. Cooling medium enters the flow channel 111 through the inlet pipe 20. Since the flow channel 111 is located near the connection hole 113, it cools the contact area. The cooling medium that absorbs heat is discharged through the outlet pipe 30, thereby reducing the temperature of the contact area and preventing conductor erosion.

[0027] Optionally, in embodiments of this utility model, the number of flow channels 111 can be one or more. When there is one flow channel 111, the flow channel 111 can be a U-shaped flow channel, which surrounds the connecting hole 113, and the liquid inlet pipe 20 and the liquid outlet pipe 30 are located on one side of the base plate 11. When there are multiple flow channels 111, the flow channels 111 can be arranged on both sides of the connecting hole 113, and the two ends of each flow channel 111 are connected to the liquid inlet pipe 20 and the liquid outlet pipe 30 respectively. When the cooling medium flows through multiple flow channels 111, it can carry away the heat of the contact area.

[0028] The output electrode base provided in this embodiment of the utility model, by setting a flow channel in the base plate and connecting the flow channel with the liquid inlet pipe and the liquid outlet pipe, can cool down the contact area between the output electrode bus and the base plate, avoid conductor ablation in the contact area, and improve the reliability and service life of the system.

[0029] like Figure 2 As shown, in one embodiment of this utility model, the inlet pipe 20 and the outlet pipe 30 are disposed on one side of the base plate 11, and the flow channel 111 forms a U-shaped flow channel within the base plate 11. The cooling medium enters the U-shaped flow channel through the inlet pipe 20 and flows along the U-shaped flow channel. The U-shaped flow channel is arranged around the connecting hole 113, which is exactly opposite to the contact area between the output bus 60 and the base plate 11, thereby effectively reducing the temperature of the contact area and preventing conductor ablation in the contact area.

[0030] like Figure 1 and Figure 3 As shown, in another embodiment of this utility model, the inlet pipe 20 and the outlet pipe 30 are respectively disposed on both sides of the base plate 11.

[0031] Specifically, such as Figure 1As shown, a pair of flow channels 111 are provided inside the base plate 11, symmetrically arranged on both sides of the connecting hole 113. Each flow channel 111 is connected at both ends to the inlet pipe 20 and the outlet pipe 30, respectively. The cooling medium enters the two flow channels 111 along the inlet pipe 20. The two flow channels 111 are located on both sides of the connecting hole 113. The cooling medium flows below the contact area between the output electrode busbar 60 and the base plate 11, thereby effectively reducing the temperature of the contact area and preventing conductor erosion in the contact area.

[0032] Furthermore, such as Figure 3 As shown, the base plate 11 is also provided with a pair of distribution chambers 112. One of the distribution chambers 112 is located near the liquid inlet pipe 20 and is connected to the liquid inlet pipe 20, and the other is located near the liquid outlet pipe 30 and is connected to the liquid outlet pipe 30. Both ends of each flow channel 111 are connected to the pair of distribution chambers 112 respectively.

[0033] Specifically, in this embodiment, the distribution chamber 112 is arranged perpendicularly to the flow channel 111. The cooling medium first enters the first distribution chamber 112 through the inlet pipe 20. When the chamber is filled with liquid, the liquid flows along the flow channel 111. The cooling medium that absorbs heat gathers in the second distribution chamber 112 and then flows out through the outlet pipe 30. The advantages of setting up the distribution chamber 112 are: on the one hand, the distribution chamber 112 provides a larger liquid storage space, which increases the contact area between the cooling medium and the contact area, thereby improving the cooling effect; on the other hand, the distribution chamber 112 can evenly distribute the cooling medium into the two flow channels 111, ensuring uniform cooling of the contact area.

[0034] In an embodiment of this invention, the output electrode base further includes a temperature sensor and a control valve. The temperature sensor is disposed on the base plate 11 and is used to detect the temperature of the base plate 11. The control valve is disposed on the inlet pipe 20 and is used to regulate the flow rate of the liquid in the inlet pipe 20.

[0035] Specifically, the temperature sensor monitors the temperature of the base plate 11 in real time. When the temperature of the base plate 11 exceeds a preset value, the control valve can be opened to allow the cooling medium to enter the flow channel 111 and cool the base plate 11. Furthermore, the valve core opening of the control valve can be adjusted according to the temperature value detected by the temperature sensor to regulate the flow rate of the cooling medium in the flow channel 111. The flow rate of the cooling medium in the flow channel 111 is larger when the temperature of the base plate 11 is higher, and smaller when the temperature of the base plate 11 is lower, so as to avoid energy waste.

[0036] like Figure 4As shown, in this embodiment of the present invention, the output electrode base 10 further includes a first washer 40 and a second washer 50. The first washer 40 is disposed on the base plate 11 and has a first through hole. The second washer 50 is disposed on the first washer 40 and has a second through hole. The outer diameter of the second washer 50 is smaller than the outer diameter of the first washer 40, and the outer surface of the second washer 50 is threaded. The diameters of the second through hole, the first through hole, and the connecting hole 113 are equal, and they are coaxially arranged. In this embodiment, the second washer 50 is used for threaded connection with an insert, which is located between the base plate 11 and the output electrode busbar 60, serving a load-bearing function.

[0037] like Figure 4 As shown, in an embodiment of this utility model, the output electrode base 10 further includes a first side plate 12, which is disposed on the base plate 11. The first side plate 12 has a first opening 121, and a portion of the output electrode bus 60 is embedded in the first opening 121.

[0038] like Figure 4 As shown, in an embodiment of this utility model, the output pole base 10 further includes a second side plate 13. The second side plate 13 is disposed on the base plate 11 and is disposed opposite to the first side plate 12. The second side plate 13 is provided with a second opening 131, and part of the support member 80 is embedded in the second opening 131.

[0039] like Figure 5 As shown, this embodiment of the present invention also provides an output electrode assembly, including: an output electrode bus 60, an adapter copper bus 70, a support member 80, fasteners, and an output electrode base 10. The adapter copper bus 70 is connected to the support member 80, and the fasteners are sequentially inserted through the adapter copper bus 70, the output electrode bus 60, and the connecting hole 113 to fix the adapter copper bus 70 and the output electrode bus 60 to the output electrode base 10. A portion of the output electrode bus 60 is embedded in the first opening 121 of the output electrode base 10, and the remaining portion extends outside the output electrode base 10. A portion of the support member 80 is embedded in the second opening 131 of the output electrode base 10, and the remaining portion extends outside the output electrode base 10.

[0040] Due to the high contact resistance at the contact area between the output bus 60 and the base plate 11 of the output base 10, localized high temperatures are prone to occur during long-term high-current operation. The base plate 11 of the output base 10 has a flow channel 111 connected to the inlet pipe 20 and the outlet pipe 30. Cooling medium enters the flow channel 111 through the inlet pipe 20. Because the flow channel 111 is located near the connection hole 113, it cools the contact area. The cooling medium that absorbs heat is discharged through the outlet pipe 30, thereby reducing the temperature of the contact area and preventing conductor erosion.

[0041] The output electrode assembly provided in this embodiment of the utility model has a flow channel set in the base plate of the output electrode base. The flow channel is connected to the inlet pipe and the outlet pipe, which can cool down the contact area between the output electrode bus and the base plate, avoid conductor ablation in the contact area, and improve the reliability and service life of the output electrode module.

[0042] Furthermore, the output electrode assembly also includes an insert, which is threadedly connected to the second washer 50 of the output electrode base 10. The insert is disposed between the first washer 40 and the output electrode bus 60, and is used to bear the weight of the transition copper bus 70 and the output electrode bus 60.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
