Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a controller busbar multi-purpose radiator and a mounting structure. Background Art

[0002] The controller bus multi-purpose heat sink is a heat dissipation device used in control systems or electronic devices, commonly found in the field of industrial automation. Its function is to effectively dissipate the heat generated by the controller to maintain a stable operating temperature of the controller or electronic device. The mounting structure is usually designed as a bracket that can be fixed on the controller or electronic device to ensure that the heat sink can effectively contact the heat source of the device and dissipate heat. In some cases, the mounting structure may also include a guide plate or heat sink interval to optimize the heat dissipation effect.

[0003] As the core component of the motor drive, the stability of the controller determines whether the motor can operate normally. In all controller products, attention has been paid to the heat dissipation of power devices. However, there has been no suitable heat dissipation method and product for the busbar with high heat generation.

[0004] Therefore, we propose a multi-purpose heat sink and mounting structure for a controller bus to solve the above problems and improve the heat dissipation problem of the bus. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-purpose heat sink and mounting structure for a controller bus bar to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a controller bus multi-purpose heat sink and mounting structure, comprising a shell and a circuit board mounted on the shell, a power device welded and mounted on one side of the circuit board, and a copper bus welded and mounted on the side of the circuit board away from the power device.

[0007] By adopting the above technical solution, when the utility model is in use, a copper busbar is installed by welding on one side, so there is no need to insulate the busbar, which can enhance the conductivity.

[0008] A mounting structure comprises an aluminum profile arranged on the top of a power device, wherein a heat dissipation fin is arranged on a side of the aluminum profile close to a circuit board.

[0009] By adopting the above technical solution, the heat dissipation area can be increased by arranging fins on the side close to the circuit board, and the heat generated by the busbar can be effectively dissipated.

[0010] Preferably, a notch groove is formed on the inner side of the heat dissipation fin, and through holes are evenly formed on a side of the aluminum profile away from the heat dissipation fin.

[0011] The above technical solution is adopted: the aluminum profile is tightly connected with the aluminum profile through the notch groove of the aluminum profile, and no insulation is required.

[0012] Preferably, the aluminum profile is pressed onto the top of the power device, and the aluminum profile is fixed to the housing by screws passing through the through holes.

[0013] The above technical solution is adopted: the aluminum profile is on the upper part of the power device, and the power device is fixed inside the shell by screws passing through the through holes.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Compared with the traditional controller bus multi-purpose radiator and installation structure, the utility model has a copper bus, an aluminum profile, a heat sink fin and a notch. The copper bus and the aluminum profile do not need to be insulated from the bus, which can enhance the conductivity. The heat sink fins can greatly increase the heat dissipation area, effectively dissipate the heat generated by the bus, and can be tightly connected to the aluminum profile through the notch without insulation.

[0016] 2. Compared with the traditional controller bus multi-purpose heat sink and installation structure, the utility model is provided with a shell, a power device, a through hole and a circuit board. The power device is arranged on the shell, the copper bus is fixed on the power device through the through hole, and the circuit board is clamped and installed inside the shell through the copper bus and the power device.
