Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a busbar structure for controlling temperature rise in a JP cabinet. Background Technology

[0002] JP cabinet refers to a JP integrated power distribution cabinet. In this cabinet, the busbar is a crucial component that connects the power output to various electrical devices. A busbar typically consists of a single conductive strip and serves as the main power output line. As an essential component of electrical equipment, the busbar is primarily responsible for connecting the power supply to various devices and transmitting signals. The busbar plays a vital role in connecting the power supply, enabling the electrical equipment to operate normally.

[0003] According to the authorized announcement number CN221669280U, a busbar structure for a JP cabinet that meets temperature rise requirements is disclosed, including a cabinet body and a pressure head. Insulating plates are fixedly connected to both sides of the cabinet body. A fixing groove is formed at the top of each insulating plate, and a busbar is engaged inside the fixing groove. Two bolts are provided on the surface of the busbar, and copper busbars are movably fitted onto the surfaces of both bolts. Nuts are threaded onto the surfaces of the bolts. During the movement of the pressure head, the cable on the surface of the winding post is squeezed to abut against the surface of the busbar. When the clamping teeth are squeezed, a spring plate moves until the pressure head can no longer press down and is released. At this point, the spring plate, due to its elasticity, unfolds to both sides, causing the corresponding clamping teeth to contact the plane of the clamping block, thereby fixing the spring plate and securing the cable on the surface of the winding post. Through the setting of the pressure head, spring plate, and clamping teeth, the cable on the surface of the winding post can be quickly fixed.

[0004] However, the above technical solution has the following drawbacks: when a large current continuously passes through the busbar, relying solely on the heat dissipation capacity of the cooling fan and the busbar's own materials makes it difficult to achieve efficient and timely heat dissipation, resulting in a continuous rise in busbar temperature, increased contact resistance, further aggravated heat generation, and impacting overall conductivity and operational safety.

[0005] Furthermore, elevated busbar temperatures can lead to risks such as insulation aging, loosening of connections, localized overheating, and even fires, affecting equipment lifespan and system reliability. Therefore, there is an urgent need for a structural design that can effectively improve busbar heat dissipation capacity and ensure stable system operation to meet the heat dissipation requirements under high-current conditions. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the above-mentioned technical solutions and provide a product that controls temperature rise, improves equipment lifespan, and enhances system reliability.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A busbar structure for controlling temperature rise in a JP cabinet includes a cabinet body and a heat-conducting plate. The cabinet body contains busbars arranged longitudinally at different depths and heights. Each busbar has several equally spaced first mounting holes. Each busbar has several equally spaced grooves on both ends, positioned between adjacent first mounting holes. One side of the heat-conducting plate has a cavity to accommodate the busbars. The heat-conducting plate has heat-conducting portions embedded in the grooves. Both ends of the heat-conducting plate have several equally spaced first heat dissipation fins. The heat-conducting plate is connected and fixed to the busbars via fastening components.

[0009] Preferably, the cavity has an inclined first guide portion at its entrance, and the heat-conducting portion has an inclined second guide portion at its entrance into the groove.

[0010] Preferably, the heat-conducting plate has a plurality of equally spaced second heat dissipation fins on the side opposite to the concave cavity.

[0011] Preferably, the busbar is provided with insulators at both ends, and the insulators are connected and fixed to the top of the cabinet.

[0012] Preferably, the inner back of the cabinet is provided with a number of heat dissipation holes located directly behind the busbar, and the heat dissipation holes are equipped with heat dissipation fans. The inner wall of the cabinet is provided with a number of air inlets located below the heat dissipation holes.

[0013] Preferably, the heat-conducting plate has at least two second mounting holes, located between two of the heat-conducting parts.

[0014] Preferably, the fastening assembly includes a fastening screw and a nut. The screw has a flat washer fitted on its shank. The fastening screw passes through a second mounting hole and a female connector in sequence. The nut is threaded onto the screw of the fastening screw, so that the heat-conducting plate is tightly connected to the female connector.

[0015] Beneficial effects:

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a heat-conducting plate in direct, tight contact with the busbar, allowing heat generated by the busbar to be conducted through the heat-conducting plate. The embedded grooves in the heat-conducting part further enhance the heat transfer efficiency between the busbar and the heat-conducting plate. The inclusion of first and second heat-dissipating fins expands the contact area between the heat-conducting plate and the air, improving heat exchange capacity. A cooling fan is positioned on one side of the first heat-dissipating fin, with its suction direction directly facing the fins, enhancing airflow speed and improving heat exchange efficiency. Furthermore, the busbar is positioned at different heights, ensuring sufficient heat exchange between the cool air and each of the first heat-dissipating fins. This structural design effectively controls the rise in busbar temperature, improving system stability and equipment lifespan. In addition, the rational structural layout reduces heat accumulation, improves the overall reliability of the cooling system, and ensures long-term stable operation of the equipment.

[0030] Reference example Figures 1 to 7 A busbar structure for controlling temperature rise in a JP cabinet includes a cabinet body 1 and a heat-conducting plate 2. The cabinet body 1 has busbars 3 arranged in a staggered manner with different heights in the longitudinal direction. Each busbar 3 has a number of equally spaced first mounting holes 32. Each end face of the busbar 3 has a number of equally spaced grooves 31, which are arranged between adjacent first mounting holes 32. One side of the heat-conducting plate 2 has a cavity 21 for accommodating the busbars 3. The heat-conducting plate 2 has a heat-conducting part 22 embedded in the groove 31. Each end face of the heat-conducting plate 2 has a number of equally spaced first heat dissipation fins 23. The heat-conducting plate 2 is connected and fixed to the busbars 3 by a fastening assembly 4.

[0031] The heat generated by the busbar 3 is conducted through the heat-conducting plate 2, which is in direct and close contact with the busbar 3. The heat-conducting part 22 is embedded in the groove 31 to further enhance the heat conduction efficiency between the busbar 3 and the heat-conducting plate 2. By setting the first heat dissipation fin 23 and the second heat dissipation fin 26, the contact area between the heat-conducting plate 2 and the air is expanded, thereby improving the heat exchange capacity. The cooling fan 6 is set on one side of the first heat dissipation fin 23, and its suction direction is directly facing the heat dissipation fin, which enhances the air flow speed and improves the heat exchange efficiency. In addition, the busbar 3 is located at different heights, which allows the cold air to fully exchange heat with each of the first heat dissipation fins 23. The above structural design effectively controls the temperature rise of the busbar 3, improves the stability of system operation and the service life of equipment. In addition, the reasonable structural layout reduces heat accumulation, improves the reliability of the overall heat dissipation system, and ensures the long-term stable operation of the equipment.

[0032] It is worth mentioning that the entrance of the cavity 21 is provided with an inclined first guide 24, and the heat-conducting part 22 is provided with an inclined second guide 25 at the entrance of the groove 31. The busbar 3 is guided into the cavity 21 by the first guide 24, which improves the smoothness of assembly. The heat-conducting part 22 is guided into the groove 31 by the second guide 25, which improves the stability and accuracy of the embedding process and reduces possible jamming or displacement during assembly.

[0033] It is worth mentioning that the heat-conducting plate 2 has several equally spaced second heat dissipation fins 26 on the side away from the recess 21. The material of the heat-conducting plate 2 can be copper or aluminum.

[0034] It is worth mentioning that insulators 5 are provided at both ends of the busbar 3. The insulators 5 are connected and fixed to the top of the cabinet 1. The busbar 3 can be installed at different heights by using insulators 5 at different heights.

[0035] It is worth mentioning that the inner back of the cabinet 1 is provided with several heat dissipation holes 11, which are located directly behind the busbar 3. The heat dissipation holes 11 are equipped with heat dissipation fans 6. The inner wall of the cabinet 1 is provided with several air inlets 12, which are located below the heat dissipation holes 11.

[0036] It is worth mentioning that the heat-conducting plate 2 is provided with at least two second mounting holes 27, which are located between two of the heat-conducting parts 22;

[0037] It is worth mentioning that the fastening assembly 4 includes a fastening screw 41 and a nut 42. The screw shank of the fastening screw 41 is fitted with a flat washer 43. The fastening screw 41 passes through the second mounting hole 27 and the busbar 3 in sequence. The nut 42 is threaded to the screw shank of the fastening screw 41, so that the heat-conducting plate 2 and the busbar 3 are tightly connected. In addition to the fastening assembly 4 tightly connecting the heat-conducting plate 2 and the busbar 3 to reduce the gap, thermal grease can also be applied between the two to further fill the gap and improve the heat conduction efficiency. The thermal grease has good thermal conductivity and a certain degree of elasticity, which can adapt to the small deformation between the busbar 3 and the heat-conducting plate 2, ensuring the thermal contact stability during long-term use. At the same time, the thermal grease has insulating properties, which can prevent the risk of short circuit caused by poor contact.
