A power supply with a protective shell

Abstract

The utility model belongs to power supply technical field especially has a protective housing's power supply, including power supply body and the protective housing body that covers power supply body setting, the protective housing body includes the protective cover and the top plate of fixed in the top of protective cover, be equipped with the lead hole on the top plate still, including two groups of symmetrical distribution's heat dissipation mechanism, and the heat dissipation mechanism of same group interval distribution has a plurality, the heat dissipation mechanism includes: heat conduction rod, the both opposite sides of protective cover all are equipped with the air hole, the heat conduction rod is fixed in the position of protective cover outer wall corresponding air hole, and the heat dissipation cavity of reverse '' L '' type is seted up in the heat conduction rod, the heat dissipation cavity with air hole are communicated, in the utility model, through the reverse '' L '' type heat dissipation cavity of heat dissipation mechanism and air hole cooperation, realize good heat dissipation, and the special structure of reverse '' L '' type heat dissipation cavity can effectively avoid the dust and water vapor of outside into the protective housing body.
