Description

Technical Field

[0001] The present invention belongs to the technical field of a snap-in bus duct, and specifically relates to a snap-in bus duct with a convection heat conduction structure. Background Art

[0002] The rise of high-end manufacturing industry is often inseparable from the construction of infrastructure. Low-voltage distribution busbars at the end of the power supply system have been widely used.

[0003] However, many bus duct products on the market currently have the phenomenon of using the same public mold for multiple products, without any independent design ideas and theories. In many cases, the bus ducts that seem to be the same have very different internal heat dissipation and conductor selection. This has caused many products to generate a lot of heat and cause abnormally serious line power loss during actual operation. Utility Model Content

[0004] In order to solve the above problems, this paper proposes a snap-on bus duct with a convection heat conduction structure, the bus duct includes a symmetrical shell and a side plate, a busbar is arranged between the inner sides of the symmetrical shell and the side plate, the shape of the symmetrical shell is a C-shaped profile, the symmetrical shell openings are arranged in a mirror image of each other in a group of two, the inner sides of the openings of the symmetrical shells are provided with side plates, the upper and lower sides of the relative surfaces of the two symmetrical shells are respectively provided with buckle side plates and hook grooves, the buckle side plates are connected to the relative hook grooves by snapping, the buckle side plates are horizontally flush with the outer surface of the symmetrical shell, and the side of the buckle side plates is provided below The hook and the buckle position of the buckle side plate are mirror-imaged and aligned with the hook groove position. A number of through holes are equidistantly arranged on the surface of the buckle side plate in the longitudinal direction. The opening of the hook groove is parallel to the outer surface of the symmetrical shell. The buckle side plates and the hook grooves of the two symmetrical shells are combined to form a busbar cavity. After being fastened together by connecting bolts, a heat-conducting cavity is naturally formed in the middle after the entire bus duct is installed. The heat generated by the conductor inside the bus duct when it is energized will naturally rise through the hollow channel, which will better improve the heat dissipation efficiency inside the bus duct, effectively reduce the conductor resistance, and extend the service life of the internal insulation layer.

[0005] The symmetrical shell is a stretched profile, and both sides of the outer side of the symmetrical shell are vertically turned outward to provide wire groove edges, and reinforcing ribs are provided at the connecting corners between the symmetrical shell and the buckle plate and the hook groove. The reinforcing ribs are integrated equilateral bevel ribs, the buckle plate and the hook groove are both vertical hooks, and the buckle plate and the hook groove are connected by mutually snap-fitting and nesting. The buckle plate is a vertical hook facing inward, and the hook groove is a vertical hook facing outward. A number of busbars are arranged side by side inside the busbar cavity, and gaps are provided between the busbars. The gaps of the busbars are aligned with the through holes. Through the two completely symmetrical symmetrical shells, a cavity naturally formed in the center after assembly can allow the airflow to circulate from bottom to top, thereby achieving excellent heat dissipation.

[0006] The side panel is in the shape of a C-shaped channel steel profile, and the outer width of the side panel is the same as the inner width of the symmetrical shell. By using the side panel to provide inner support to the inner side of the symmetrical shell, not only can the side of the symmetrical shell be spaced and protected, but it can also play a role in support and reinforcement.

[0007] Connecting bolts are provided on the inner side of the through holes in an upward and downward manner. The connecting bolts are arranged in a row of longitudinally equidistant through holes. A fixing bolt is installed between every two through holes during splicing and assembly. The remaining through holes are hot air flow rising channels, which effectively reduce the temperature of the non-heat-dissipating area inside the bus duct.

[0008] Beneficial effects:

[0009] It is mainly used in dense bus ducts. The changes in the heat radiation field of the bus duct shell are analyzed through finite element technology, and a new three-dimensional structure is designed. The entire bus duct is composed of two separate channels, which are positioned and engaged by the upper and lower buckle plates and hook grooves on the bottom of the symmetrical shell. After being fastened by connecting bolts, after the entire bus duct is installed, a heat-conducting cavity is naturally formed in the middle. The heat generated by the conductor inside the bus duct will naturally rise through the hollow channel, which can better improve the internal heat dissipation efficiency of the bus duct, effectively reduce the conductor resistance and extend the service life of the internal insulation layer.

[0010] Through two completely symmetrical shells, the cavity naturally formed in the center after assembly allows air to circulate from bottom to top, thereby achieving excellent heat dissipation.

[0011] By using side panels to provide inner support to the inner side of the symmetrical shell, not only can the sides of the symmetrical shell be protected by intervals, but it can also play a role in supporting and strengthening.

[0012] During splicing and assembly, a fixing bolt is installed between every two through holes, and the remaining through holes serve as hot air flow rising channels, effectively reducing the temperature of the non-heat-dissipating areas inside the bus duct. BRIEF DESCRIPTION OF THE DRAWINGS
