Embodiment Construction
[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0024] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the difference between components in a specific posture (as shown in the accompanying drawings). If the relative positional relationship, movement situation, etc. change, the directional indication will change accordingly.
[0025] In addition, the descriptions r...

The invention provides a heat dissipation structure and a frequency converter. The heat dissipation structure comprises a heat generating device, a heat sink and a mounting panel; the heat generatingdevice is connected to the heat sink; the heat sink is connected to the mounting panel; the heat dissipation structure is mounted on a wall through the mounting panel; a mounting surface of the mounting panel is provided with protruding portions extending toward the wall; the protruding portions are arranged along a vertical direction of the mounting surface; the protruding portion includes a first surface and a second surface that are connected to each other; and a cross section of the protruding portion along a lateral direction of the mounting surface is a triangle. Since the mounting panelhas good heat transfer, the design of the protruding portions increases the surface area of the mounting panel, that is, the surface area of the heat sink is increased; therefore, the heat dissipation effect of the heat generating device is improved without increasing the overall volume of the device.
Description
Technical field [0001] The invention relates to the field of heat dissipation, in particular to a heat dissipation structure and a frequency converter. Background technique [0002] With the development of the times, the automation applications in the mechanical field continue to increase, making the application of electronic equipment such as frequency converters more and more extensive. The frequency converter is one of the important components indispensable for modern motor speed regulation and energy saving. The application is very wide, but the shortcomings of the frequency converter are also reflected in a wide range of applications. The main circuit of the inverter is composed of three parts: rectifier, intermediate circuit, and inverter. These components generate a lot of heat during operation. If they cannot effectively dissipate heat, the inverter will be damaged due to excessive temperature. [0003] At present, the heat dissipation system of the frequency converter pla...
