Convenient-to-disassemble and assemble cooling power supply box

Abstract

The invention discloses a convenient-to-disassemble and assemble cooling power supply box, which comprises a power supply box profile, wherein a screw groove is formed in the bottom of the inner side of the power supply box profile; a power adapter plate is fixedly arranged in the power supply box profile by the power supply box profile through the screw groove and a waist-shaped hole formed in the power adapter plate; the top of the power adapter plate is fixedly connected with the bottom of a power supply; and a sliding block is arranged at the outer side of the power supply box profile and is in sliding connection with a slide chute in the inner side of a power cover plate. The power adapter plate and the power supply are fixedly arranged at the inner side of the power supply box profile through the formed screw groove and waist-shaped hole, the power cover plate is movably arranged at the top of the power supply box profile through the arranged sliding block and the formed slide chute, the heat dissipation effect of the power supply box is better through arranged connection plate, heat-conducting plate and trapezoidal block, and the power supply box is sealed through arranged lower end cover and upper end cover, so that the effect of preventing the power supply box from being burnt out by an over-high temperature in the power supply box is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical parts, in particular to a heat dissipation power supply box which is easy to assemble and disassemble. Background technique [0002] The power box is an electrical device that converts 220 volts of alternating current into a constant and stable low-voltage direct current. Generally, the input 220v output is 24v, 36v, 12v, 5v for small electrical appliances, because the input used by different household appliances on the market The voltage is also different, so most household appliances will be equipped with a power box to prevent damage to the appliance caused by excessive power supply voltage. When the power supply box is damaged, it is difficult to disassemble it for maintenance, and the power supply box often burns out when the temperature is too high during work. Contents of the invention [0003] The purpose of the present invention is to provide a heat dissipation power supply box that...
