Problems solved by technology
And because the power distribution cabinet belongs to electrical equipment, if water-cooling technology is used, the sealing performance is very high. Once the water-cooling equipment leaks, it will cause irreparable losses.
At present, most of the power distribution pipes are cooled by fans or air conditioners. This cooling method also requires additional power supply equipment to operate, and it will generate a lot of heat itself.

A power distribution box relates to an electrical apparatus; the power distribution box comprises a box body; electrical devices are arranged inside the box body; the box body is provided with an air inlet port and an air outlet port; the box body is provided with a bracket; the bracket is provided with a spindle; the spindle is provided with a balancing plate; the bracket is provided with a check block which is matched with the balancing plate; the top of the box body is provided with an upright column; the bottom of the upright column is provided with a coned sealing plug; the coned sealing plug is provided with a movable ultrathin plastic piece; the ultrathin plastic piece is provided with a super fine steel wire; the super fine steel wire is connected with one end of the balancing plate; a supporting rod is further arranged inside the box body; the supporting rod is provided with a miniature spindle; the miniature spindle is provided with a rotation lever; the rotation lever is provided with an ultrathin fan blade; a connection column is connected between the balancing plate and the rotation lever. The power distribution box uses the heat energy emitted by the electrical devices arranged inside the power distribution box as a drive source for driving the fan inside the power distribution box to run, so as to reinforce the air convection and accelerate the heat dissipation; the device does not need a heat dissipation device requiring additional electricity, thereby reducing the electricity consumption and avoiding other heat source occurring in the power distribution box.
Description
technical field [0001] The invention relates to electric equipment, especially a distribution box. Background technique [0002] In the field of power distribution cabinets, due to the installation of a large number of connectors and various electronic components in the power distribution cabinet, and the existence of a large number of wires, the total resistance of the power distribution cabinet is very high, because it will A large amount of heat is emitted, causing the temperature of the distribution cabinet to suddenly increase. And because the power distribution cabinet belongs to electrical equipment, if water-cooling technology is used, the sealing performance is very high. Once the water-cooling equipment leaks, it will cause irreparable losses. At present, most of the power distribution pipes are cooled by fans or air conditioners. This cooling method also requires additional power supply equipment to operate, and it will generate a lot of heat itself. The current...
