Problems solved by technology
Once in summer, due to the high ambient temperature, the temperature in the cabinet will continue to rise after the components are heated. In addition, the cooling effect of the air is poor, and the temperature in the cabinet cannot be quickly reduced, which will affect the performance of the components and cause the control cabinet. Running speed slows down, or even crashes
Moreover, the components are in a high temperature environment for a long time, which is easy to shorten the service life of the components

The invention relates to a heat dissipation method and system of a sealing cabinet body. The method comprises steps that the first gas concentration with a heat conductivity coefficient larger than that of air in the cabinet body is detected; when the first gas concentration is smaller than a first preset threshold value, the air in the cabinet body is exhausted; the cabinet body is filled with the first gas till the concentration of the first gas is greater than or equal to a first preset threshold, so the first gas circularly flows between the cabinet body and a cooling device for heat dissipation. As the heat conductivity coefficient of the first gas is greater than that of the air, the air and the first gas with the same volume can take away more heat, and thereby the temperature in the cabinet body is quickly reduced, and components in the cabinet body are made to work in the proper-temperature environment, the stability of the components can be ensured, and the cabinet can operate normally; and the service life of the components can be ensured.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a heat dissipation method and system for a sealed cabinet. Background technique [0002] There are many kinds of control cabinets, such as frequency conversion control cabinets, high and low voltage control cabinets, explosion-proof control cabinets, etc. There are a large number of components in the control cabinet. Since the components cannot work for a long time in a high temperature environment, it is necessary to dissipate heat from the components. In the prior art, the cooling of the control cabinet mostly uses air as the medium, but the cooling effect is poor. It's okay in winter, because the ambient temperature is low, so it has less impact on components. Once in summer, due to the high ambient temperature, the temperature in the cabinet will continue to rise after the components are heated. In addition, the cooling effect of the air is poor, and the tempe...
