For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood in specific circumstances. In addition, in the description of the utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0017] See also Figure 1-2The utility model provides an embodiment: a control cabinet resistor heat dissipation bracket, comprising a bracket body 1 mounted on the back of a resistor 6 and two mounting parts 2 respectively arranged at the upper and lower ends of the bracket body 1. The bracket body 1 is specifically a plate-like structure, and through holes are arranged through the resistor 6 and the bracket body 1. The resistor 6 is fixed to the front end surface of the bracket body 1 by bolts. A thermal conductive silicone pad 4 is arranged on the abutting surface of the bracket body 1 and the resistor 6, which can reduce the gap between the two and quickly conduct the heat generated by the resistor 6 when working. Furthermore, the thermal conductive silicone pad 4 can also be set as thermal conductive silicone grease.

[0018] The mounting portion 2 includes a support section 201 connected to the bracket body 1 and a mounting plate 202 vertically bent and arranged at one end of the support section 201 away from the bracket body 1. A mounting hole 2021 is penetrated through the mounting plate 202. The mounting portion 2 is bent and formed integrally with the bracket body 1. During assembly, the mounting plate 202 is abutted against the mounting plane and then bolts are passed through the mounting holes 2021 for installation and fixation. The mounting plate 202 can reduce the contact area with the mounting plane to avoid direct heat transfer to the adjacent resistor 6 or other electrical components.

[0019] The mounting portion 2 is located on the back of the bracket body 1 . The back of the bracket body 1 is provided with a plurality of heat dissipation fins 3 and a heat dissipation fan 5 for driving air flow around the heat dissipation fins 3 .

[0020] The bracket body 1 and the heat dissipation fins 3 are integrally formed, and the material of the bracket body 1 and the heat dissipation fins 3 is aluminum, which can increase the contact area with the air. In the present embodiment, the heat dissipation fins 3 are specifically a vertical plate-like structure, and can also be set to other shapes such as a wavy shape as needed to increase its surface area, thereby increasing the heat exchange area, and quickly dissipating the heat generated by the resistor 6 during operation, avoiding heat accumulation, and shortening the service life of the resistor 6.

[0021] A plurality of heat sink fins 3 are vertically arranged at equal intervals on the back of the bracket body 1. The width of the heat sink fin 3 is smaller than the length of the support section 201, so that during assembly, a gap is reserved between the back of the heat sink fin 3 and the installation plane. At the same time, the length of the heat sink fin 3 is smaller than the spacing between the two support sections 201, which facilitates the flow of air between the heat sink fins 3. Furthermore, through holes can also be set on the heat sink fin 3.

[0022] There is one cooling fan 5, which is mounted on the support section 201 at the top of the cooling fin 3 by bolts. A vent 2011 is provided through the support section 201 to drive air to flow between the cooling fins 3, thereby achieving a better cooling effect.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
