Multiple heat sinks are used, spaced apart. The heat sink base has a mounting groove, and the mounting base is installed in the mounting groove. The heat sink fin in this application can be removed for cleaning, ensuring that dust on the heat sink is thoroughly cleaned, thus ensuring that the heat dissipation effect is not affected by dust.

[0004] The above-mentioned device has certain shortcomings in use: when the device is working, the heat sink is arranged closely together, and when heat is dissipated, heat may accumulate as it passes through the heat sink, affecting the overall heat dissipation effect.

[0005] To address these issues, this invention provides a heat-dissipating copper busbar for frequency converters. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a heat-dissipating copper busbar for frequency converters, thus solving the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat-dissipating copper busbar for a frequency converter, including a U-shaped frame, a sliding component installed on the inner wall of the U-shaped frame, a clamping component installed on the top wall of the sliding component, and a heat-dissipating copper busbar body installed on the top wall of the clamping component;

[0008] The sliding assembly includes several positioning rods, each fixedly connected to the inner wall of the U-shaped frame. Several slide blocks are slidably installed on the outer walls of the positioning rods. Square grooves are opened on the bottom side walls of the slide blocks. Limit grooves are opened at the front and rear parts of the outer side walls of the slide blocks. Through openings are opened on the front and rear walls of the slide blocks. Several locking slots are evenly opened on the front and rear walls of the U-shaped frame. The locking slots and the inner walls of the corresponding through openings are evenly engaged with the same locking post. The ends of the locking posts that are far apart from each other are fixedly installed with the same positioning seat.

[0009] Through the above technical solution, the sliding component can flexibly adjust the spacing between the heat dissipation copper busbars, thus providing good versatility in use. The overall adjustment method is also relatively simple, and the busbars are stable and do not wobble after adjustment.

[0010] Furthermore, several positioning rods are all square, and the positioning rods are evenly arranged front and back.

The outer walls of several positioning seats are evenly fitted to the outer walls of the corresponding sliding seats.

[0011] Through the above technical solution, several sliding blocks slide along the outer wall of the positioning rod through square grooves to adjust their positions.

[0012] Furthermore, the mounting assembly includes several mounting bases, the number of which is the same as the number of heat dissipation copper busbars, and the top walls of the mounting bases are fixedly connected to the bottom walls of the corresponding heat dissipation copper busbars.

[0014] Furthermore, positioning blocks are fixedly installed on the front and rear walls of several heat dissipation copper busbars, and mounting brackets are fixedly installed on the bottom walls of several positioning blocks.

[0015] Through the above technical solution, the positioning block and its mounting base work together to snap into the inside of the mounting hole, thereby completing the installation and fixing of the heat dissipation copper busbar body.

[0016] Furthermore, several sliding blocks have locking holes on their top and front walls and corresponding to the positions of the card holders, and the inner walls of these locking holes are engaged and fixed to the outer walls of the corresponding card holders.

[0017] Through the above technical solution, the cooperation between the card hole and the card holder enables the rapid installation of the heat dissipation copper busbar, and it can be quickly removed afterward for easy cleaning of its surface.

[0018] Furthermore, each of the top walls of several slides is provided with a positioning groove, the inner wall of each positioning groove is fitted with the outer wall of the corresponding mounting seat, and a limit baffle is fixedly installed on the outer wall of each mounting seat, the inner wall of each limit baffle is fitted with the outer wall of the corresponding slide.

[0019] The above technical solution uses the positioning groove in conjunction with the mounting base, and limits the mounting base and the heat dissipation copper busbar body by using the limiting baffle to prevent them from shifting position.

[0020] Furthermore, mounting ears are fixedly installed on the outer side walls of the U-shaped frame, and mounting holes are opened on the front and rear parts of the top wall of the two mounting ears.

[0021] Through the above technical solution, the mounting ears and mounting holes work together to complete the installation and fixation of the entire device.
