Description

Technical Field

[0001] The utility model belongs to the field of electrical equipment, and particularly relates to a heat dissipation structure of equipment. Background Art

[0002] When electrical equipment is working, it is easy to generate a lot of heat energy, causing the temperature to rise; however, too high a temperature will affect the normal operation of the electrical equipment and even the service life of the electrical equipment, so the heat dissipation structure of the electrical equipment is crucial.

[0003] As disclosed in the prior patent, a floodlight that is easy to dissipate heat (application number CN201821721792.1) relates to the field of lighting devices, including a lamp frame, a heat conducting plate is sealed and fixed in the lamp frame, a transparent lens is fixed at the opening of the lamp frame, a plurality of lamp beads are fixed on the side of the heat conducting plate close to the transparent lens, a plurality of heat dissipation fins are fixed in parallel on the side of the heat conducting plate away from the transparent lens, a battery box is fixed on the lamp frame, the battery box is in contact with the side of the heat dissipation fin away from the heat conducting plate, and a battery for powering the lamp beads is installed in the battery box. In the floodlight, external air enters the battery box driven by a fan, and is discharged from the battery box through the heat dissipation fins to dissipate heat for the heat conducting plate; however, although the air flow guided by the fan passes through the battery box, it does not directly correspond to the battery, resulting in a relatively insufficient heat dissipation effect on the battery; and because the floodlight is composed of a multi-layer structure such as a lamp frame and a battery box, its overall thickness is thicker.
