In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a low pressure pull-out type cubical switchboard, includes the cabinet body, the internal chamber of accomodating that two were no less than to be provided with quantity of cabinet accomodates the intracavity and is provided with electrical components's drawer with drawable, the bottom of drawer is provided with the radiating part, and the radiating part is the box-like of no top, and the inside of radiating part is provided with the baffle, and the inside snakelike wind channel that keeps apart into of radiating part is shielded to the baffle, and the both ends in wind channel are air intake and air outlet respectively and are located the preceding terminal surface of radiating part, install the fan in the air intake, and the circular telegram module setting of fan is in the drawer.

As a preferred technical scheme of the utility model, accomodate and be provided with the spout on the inner wall in chamber, the corresponding position department of radiating part side is provided with the slide rail, and the slide rail slides and sets up in the spout.

As an optimized technical proposal of the utility model, the front end face of the drawer is provided with a pull groove, and the front end of the drawer is provided with a lock.

As a preferred technical scheme of the utility model, air intake and air outlet department all are provided with the dust screen.

As an optimized technical scheme of the utility model, the bottom at the drawer is fixed through the connecting hole of its four corners department to the radiating part, and the top of baffle and the lower bottom surface contact of drawer.

Compared with the prior art, the beneficial effects of the utility model are that: this low-voltage pull-out type cubical switchboard dispels the heat alone to each drawer of installing electrical components, need not the unified wind channel of internal design of cabinet, therefore the radiating effect can not receive the restriction of drawer quantity, has guaranteed stable radiating effect, has improved the stability and the security of cubical switchboard long-time operation.
