technical field

The invention relates to the technical field of electronic equipment, in particular to a cabinet radiator and a cabinet.

Background technique

In order to improve the protection effect of the electronic equipment in the cabinet, it is necessary to improve the waterproof and dustproof level of the cabinet. Therefore, an airtight cabinet is usually prepared. In order to ensure that the electronic equipment can work normally and reliably within the allowable operating temperature range, the outdoor airtight cabinet must have a certain heat dissipation function to transfer the heat generated by the electronic equipment to the outside of the cabinet. If the cooling capacity of the cabinet wall itself cannot meet the requirements, cooling components such as air conditioners or heat exchangers are usually installed to improve the cooling capacity of the cabinet, but it will also bring certain disadvantages. For example, the cost of the cabinet is higher if new heat dissipation components are added; or the thermal resistance of the heat dissipation components is large, the heat dissipation effect is poor, and it is difficult to achieve natural heat dissipation; or the size of the heat dissipation components is large, occupying more space in the cabinet.
