Abstract
Description
Technical Field
[0001] This utility model relates to the field of dense busbar trunking technology, and more specifically to a dense busbar trunking with good heat dissipation performance. Background Technology
[0002] High-density busbar trunking is mainly composed of high-purity electrolytic copper (or aluminum) busbars, insulating materials, and a metal casing. The copper (or aluminum) busbars act as conductors, and are double-wrapped with insulating material to ensure insulation. Each copper busbar is closely spaced, forming a "sandwich" conductor structure. This structure results in a dense busbar trunking along its entire length, preventing a "chimney effect," and also creates a compact structure that occupies less building space.
[0003] Existing high-density busbar trunking systems have some shortcomings in their use, as follows:
[0004] During prolonged high-power operation, the copper (or aluminum) busbars inside the busbar trunking will generate a large amount of heat, causing the overall temperature of the equipment to rise. Therefore, the existing equipment may experience overload and short circuit during long-term use, making it unsuitable for prolonged high-power operation. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dense bus trunking with good heat dissipation performance to solve the problems existing in the background art.

[0007] Furthermore, the positioning housing includes a housing body, with heat dissipation plates fixedly connected to the top and bottom of the housing body. A square positioning groove is provided on the inner side of the housing body, and a U-shaped positioning groove is provided on the top and bottom of the square positioning groove. A first positioning hole is provided on both sides of the housing body, and a second positioning hole is provided on both sides of the U-shaped positioning groove.
[0008] Furthermore, the heat dissipation assembly includes a square plate, a connecting pipe is fixedly connected to one side of the square plate, a third positioning hole is opened on both sides of the square plate, and a U-shaped connecting pipe is fixedly connected to the other side of the third positioning hole.
[0009] Furthermore, the width of the square plate and the width of the U-shaped positioning groove are fitted with a clearance, and the height of the square positioning groove and the height of the copper plate body are fitted with a clearance.
[0010] Furthermore, the diameter of the second positioning hole is clearance-fitted with the diameter of the connecting pipe, and the diameter of the U-shaped connecting pipe is clearance-fitted with the diameter of the first positioning hole.
[0011] Furthermore, the spacing between the square plates is clearance-fitted with the thickness of the copper plate body, and the cross-sectional dimensions of the space formed by the square plates at the edge of the heat dissipation component and the square positioning groove are clearance-fitted with the cross-sectional dimensions of the outer shell body.

[0013] The technical effects and advantages of this utility model are as follows:
[0014] In this invention, the circular positioning holes on both sides of the copper plate assembly allow the temperature of the copper plate body to rise during operation. The coolant inside the square plate absorbs the heat generated by the copper plate assembly, and the liquid inside each square plate circulates through connecting pipes. The U-shaped connecting pipes effectively dissipate the heat generated by the liquid, allowing the heat generated during operation to be quickly absorbed and transferred to the outside through the U-shaped connecting pipes. The heat sink further dissipates the heat generated by the equipment, ensuring that the equipment can maintain high power for extended periods. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Reference Figure 1-4 This utility model provides a high-density busbar trunking with good heat dissipation performance, including a positioning shell 1, a copper plate assembly 2 fixedly connected to the inner side of the positioning shell 1, and a heat dissipation assembly 3 fixedly connected to the inner side of the positioning shell 1. The copper plate assembly 2 includes a copper plate body 201, with positioning rounded corners 202 on both sides of the copper plate body 201, and circular positioning holes 203 on both sides of the front of the copper plate body 201. During operation, the circular positioning holes 203 on both sides of the copper plate assembly 2 will cause the temperature of the copper plate body 201 to rise. The temperature rises, and then the coolant inside the square plate 301 absorbs the heat generated by the copper plate assembly 2 during operation. Then, the liquid inside each square plate 301 is circulated through the connecting pipe 304, and the temperature of the liquid is effectively dissipated through the U-shaped connecting pipe 302. This allows the heat generated by the equipment during operation to be quickly absorbed, and the temperature can be transferred to the outside through the U-shaped connecting pipe 302. Furthermore, the heat dissipation plate 102 can further transfer the heat generated by the equipment during operation to the outside, ensuring that the equipment can maintain high power for a long time.
[0022] Furthermore, the positioning housing 1 includes a housing body 101, with heat sinks 102 fixedly connected to the top and bottom of the housing body 101. A square positioning groove 103 is provided on the inner side of the housing body 101, and a U-shaped positioning groove 104 is provided on the top and bottom of the square positioning groove 103. A first positioning hole 105 is provided on both sides of the housing body 101, and a second positioning hole 106 is provided on both sides of the U-shaped positioning groove 104.
[0023] Furthermore, the heat dissipation component 3 includes a square plate 301, a connecting pipe 304 is fixedly connected to one side of the square plate 301, and third positioning holes 303 are opened on both sides of the square plate 301. A U-shaped connecting pipe 302 is fixedly connected to the other side of the third positioning hole 303.
[0024] Furthermore, there is a clearance fit between the width of the square plate 301 and the width of the U-shaped positioning groove 104, and a clearance fit between the height of the square positioning groove 103 and the height of the copper plate body 201.
[0025] Furthermore, the diameter of the second positioning hole 106 is clearance-fitted with the diameter of the connecting pipe 304, and the diameter of the U-shaped connecting pipe 302 is clearance-fitted with the diameter of the first positioning hole 105.
[0026] Furthermore, the spacing between the square plates 301 is clearance-fitted with the thickness of the copper plate body 201, and the cross-sectional dimensions of the space formed by the square plates 301 at the edge of the heat dissipation component 3 and the square positioning groove 103 are clearance-fitted with the cross-sectional dimensions of the outer shell body 101.
[0027] Furthermore, the diameter of the third positioning hole 303 is clearance-fitted with the diameter of the connecting pipe 304, and the number of U-shaped connecting pipes 302 on the square plate 301 is the same as the number of connecting pipes 304.
[0028] The working principle of this utility model is as follows: During operation, the temperature of the copper plate body 201 rises at the circular positioning holes 203 on both sides of the copper plate assembly 2. The heat generated by the operation of the copper plate assembly 2 is absorbed by the coolant inside the square plate 301. The liquid inside each square plate 301 is circulated through the connecting pipe 304, and the temperature of the liquid is effectively dissipated through the U-shaped connecting pipe 302. This allows the heat generated by the equipment during operation to be quickly absorbed, and the temperature can be transferred to the outside through the U-shaped connecting pipe 302. Furthermore, the heat dissipation plate 102 can further transfer the heat generated by the equipment to the outside, ensuring that the equipment can maintain high power for a long time.
[0029] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
