Abstract

The invention provides a cabinet device with heat insulation and ventilation function and a control cabinet using the cabinet device. The cabinet device includes a cabinet body and a heat shield, and a ventilation air passage is formed between the cabinet body and the heat shield. The top wall of the cabinet is provided with an exhaust hole that communicates with the inner cavity of the cabinet and the ventilation air passage so that the gas in the inner cavity of the cabinet enters the ventilation air passage. An exhaust fan is provided at the exhaust hole, and the exhaust hole has a The upper orifice connected to the ventilation air passage and the upper orifice of the exhaust hole are arranged with a gravity self-sealing cover, which includes a cover for sealing the upper orifice, and the cover is hinged on the exhaust hole. The upper orifice of the air hole is or guided and moved in the up and down direction and installed above the upper orifice of the air exhaust hole. The gravity self-sealing cover not only ensures that the exhaust holes can be better closed when the exhaust fan stops working, but also does not affect the normal ventilation of the cabinet body, and the overall structure is simple, and the production design cost is low.

Description

technical field [0001] The invention relates to a cabinet device with heat insulation and ventilation functions and a control cabinet using the cabinet device. Background technique [0002] At present, the secondary element control cabinets such as HSBC cabinets for outdoor use are all made of single-layer metal plates, which are characterized by convenient processing, good weather resistance, and high impact resistance of metal structures. However, the performance of the ventilation system of this kind of cabinet is not ideal in high temperature and high sunshine areas (such as Hainan and other regions). The main reason is that the metal cabinet itself has better heat conduction effect. The space inside the cabinet and the electrical components installed in the cabinet will cause the temperature of the gas in the cabinet to rise rapidly; in addition, the ventilation system of the conventional HSBC cabinet cannot quickly replace the gas in the cabinet, which will eventually ...
