Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a constant temperature, constant humidity and dustproof intelligent electrical cabinet. Background Art

[0002] Gas cabinets are cabinets made of steel and used to protect the normal operation of components. Electrical cabinets are widely used and are mainly used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN212230811U discloses an intelligent electrical cabinet, including a cabinet body, one side of the cabinet body is rotatably connected to the cabinet door, an air inlet and an exhaust hole are provided on one side of the cabinet body, an air inlet fan is installed at the air inlet, and an exhaust fan is installed at the exhaust hole. It is characterized in that an air inlet and exhaust conversion device is provided on one side of the cabinet body, a vertically arranged upright pole is fixedly connected in the cabinet body, a cooling device is slidably connected on the upright pole, and a power device for driving the cooling device to move up and down is also provided in the cabinet body. The utility model can be used in a humid environment. When the outside air enters the interior of the electrical cabinet, the water in the air will be absorbed, which makes up for the problem in the prior art that the use of the electrical cabinet in a humid environment will shorten the service life of the internal electrical components. When the temperature inside the electrical cabinet is higher than the set value, the temperature transmitter will automatically control the cooling. During the cooling process, the dust attached to the surface of the electrical components can also be blown off, thereby increasing the service life of the electrical components.

[0004] Existing electrical cabinets generally dissipate heat through fans. When the fan drives the airflow, it also brings external dust into the electrical cabinet. At the same time, existing electrical cabinets cannot control the humidity inside the electrical cabinet. When the humidity is too high, internal circuit components may short-circuit.
