[0002] With the continuous development of electronic assembly technology, the size of electronic power equipment tends to be miniaturized, the system tends to be complex, and high heat density has become an irresistible development trend. In order to adapt to the needs of high heat density and ensure the normal operation of the system, traditional heat dissipation means such as fans and radiators are constantly being innovated; the existing structure of heat dissipation inside the cabinet for power equipment is generally to dissipate heat through airflow, by conveying airflow to the inside of the cabinet, and carrying and outputting the heat inside the cabinet through the airflow, so as to achieve heat dissipation inside the cabinet. When the airflow is input, the input airflow will be filtered through the filter to prevent the airflow from carrying impurities in the air into the cabinet. However, when the airflow is input for a long time, the filter is continuously filtered, which will cause the filter to be blocked, and the outer side of the filter will be blocked and accumulated with impurities, so that the airflow cannot enter the cabinet smoothly, and then the heat dissipation effect inside the cabinet is sharply reduced, affecting the normal operation of the power equipment inside the cabinet. For this reason, it is necessary to upgrade the cabinet thermal conductivity and heat dissipation structure to avoid the occurrence of heat dissipation problems. Summary of the invention
