Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat dissipation system for an electric control box, an electric control box with the heat dissipation system, and a control method for the heat dissipation system for the electric control box. Background technique [0002] During the long-term operation of electrical equipment such as electromechanical and household appliances, the internal components of the electric control box will heat up. If the heat dissipation conditions are not ideal, the internal temperature of the box will gradually rise, which may lead to the continuous deterioration of the working environment of some electrical components. It affects the performance parameters and service life of components, and even has certain safety hazards. [0003] In related technologies, for small and medium-sized electric control boxes of household appliances, heat dissipation aluminum is generally added to some hig...

Problems solved by technology

[0004] However, although the above-mentioned traditional heat dissipation methods can also achieve corresponding heat dissipation effects, with the development and application of some high-precision equipment, these heat dissipation methods may be more effective in terms of temperature adjustment speed, automation, intelligence, and temperature adjustment range. or less defects

For example, in order to achieve the heat dissipation effect, the area of ​​heat dissipation aluminum often needs to reach dozens or even hundreds of times the area of ​​the temperature-regulated object. The space is severely limited, and it is affected by many factors such as airflow and ambient temperature; Accelerate air convection and strengthen heat dissipation, but in the high temperature electric control box, this heat dissipation method cannot achieve a large cooling; as for the use of air conditioners for heat dissipation, although the effect is good, the energy consumption is too high and not energy-saving enough
