Description

Heat radiation structure of combined drawer switch cabinet

Technical Field

The utility model relates to a cubical switchboard, concretely relates to modular drawer cubical switchboard's heat radiation structure.

Background

The drawer type switch cabinet is a closed shell made of steel plates, electrical elements of a wire inlet and outlet loop are all installed in an extractable drawer to form a functional unit capable of completing a certain power supply task, and the roller is vertically arranged in a traditional drawer type structure, rolls in a guide rail, and easily falls into foreign matters in a groove of the guide rail to cause the derailment of the roller.

In the operation process of the switch cabinet, the phenomenon of overhigh temperature can occur, so that internal components are damaged, and therefore the switch cabinet needs to be periodically cooled and cooled. Traditional cubical switchboard adopts trompil on automatically controlled cabinet wall mostly, makes inside heat scatter through this hole, but this kind of radiating effect is relatively poor, is difficult to reach good ventilation radiating effect. The louvre is when providing the heat dissipation function, and inside some mosquitoes also can enter into the cubical switchboard easily, influence the normal work of electric power components and parts in the cubical switchboard, even cause the short circuit. Now in order to prevent that the mosquito from flying into the inside of cubical switchboard, adopt more that the inside of the cabinet body is relative with the louvre position sets up the kill mosquito electric wire netting, when the mosquito flies into the inside of cubical switchboard through the louvre, the mosquito hits on the kill mosquito electric wire netting to kill through the kill mosquito electric wire netting. Therefore, although the mosquitoes are prevented from entering, the corpses of the mosquitoes are easy to be left on the mosquito killing electric net and are not easy to clean.

The cubical switchboard base is used for the cover to establish the utensil in cubical switchboard bottom, can play the effect of abrasionproof loss to the cubical switchboard bottom, but the simple of present cubical switchboard structure all ten minutes, and a base cover that is rectangle box-like establishes on the bottom of cubical switchboard promptly, and the antidetonation effect of base is relatively poor, and the inboard electrical component of cubical switchboard receives undulant influence great in the use, influences its normal use.
