Temperature-adjustable electrical cabinet

Abstract

The invention relates to a temperature-adjustable electrical cabinet comprising a cabinet body, a placing plate and a temperature adjusting device are arranged on the cabinet body, and the temperature adjusting device comprises a semiconductor chilling plate arranged on the side wall of the cabinet body and air guide fans arranged on the two sides of the semiconductor chilling plate respectively; the cabinet also includes air guide pipes arranged in the cabinet body; the air guide pipes comprise an air inlet pipe and air exhaust pipes, a built-in air guide fan and the semiconductor chilling plate are arranged in the air inlet pipe, the air exhaust pipes are communicated with the air inlet pipe, the number of the air exhaust pipes is at least two, and air outlet holes are densely distributed in the air exhaust pipes. The exhaust pipes are parallel to the placing plate, and the farther the exhaust pipes are away from the air inlets of the air inlet pipes, the more the air outlet holes are formed in the exhaust pipes. The electrical cabinet can be refrigerated or heated, meanwhile, the structure is reasonable, and energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an electric cabinet with adjustable temperature. Background technique [0002] Electrical cabinets are cabinets used to protect the normal operation of electrical components. Usually, there are multiple electrical components in one electrical cabinet. Electrical cabinets are widely used in environmental protection industry, power system, metallurgical system, nuclear power industry, fire protection and transportation industries. Although most of the electrical cabinets are located indoors at present, there are still some electrical cabinets in fields such as power systems, environmental protection industries, and transportation industries located outdoors. [0003] The electrical parts in the electrical cabinet need to operate normally under certain temperature conditions. In summer, due to the heat generated by the operation of the electrical parts themselves, coupled...

AI Technical Summary

Problems solved by technology

But its existing problem is: the work of the electrical cabinet located outside is not considered under cold conditions; at the same time, after the air passes through the blower, due to the working characteristics of the blower, the air passing through the blower will be heated, resulting in the air entering the electrical cabinet. The temperature of the air is higher than that of the outside air, resulting in a decrease in cooling efficiency

However, this device also has the following problems: it does not consider the work of the electrical cabinet located outdoors under cold conditions; at the same time, the fan used for air circulation is installed inside the cabinet, and the main body will generate heat when the fan is running, resulting in cooling. less efficient
