Equipment cabinet

Abstract

The invention provides an equipment cabinet. The equipment cabinet comprises a box body, an environment temperature inductor, a temperature controller and a semiconductor refrigeration system, wherein the environment temperature inductor, the temperature controller and the semiconductor refrigeration system are installed in the box body, and when the temperature detected by the environment temperature inductor reaches or exceeds a temperature value set by the temperature controller, the semiconductor refrigeration system starts to generate cold air in the box body. The working principle of the semiconductor refrigeration system is safe, reliable, simple and easy to achieve.

Description

technical field [0001] The invention relates to a cabinet, in particular to a cabinet that needs cooling. Background technique [0002] With the continuous development of science and technology, electronic components are becoming more and more sophisticated, and various precision equipment are widely used in our electric power, communication, public security monitoring and other fields, such as switches, intelligent terminals, etc. At the same time, many precision equipment realize their unique functions by installing corresponding power supply equipment, lightning protection functions, signal output equipment, etc. in closed boxes such as cabinets, battery cabinets, and control boxes. The working temperature range of these precision equipment is certain, and its performance will be affected if the temperature is too high or too low. In addition to the self-heating of the equipment, it is also affected by the surrounding environment. In areas where the temperature is more su...

AI Technical Summary

Problems solved by technology

The working temperature range of these precision equipment is certain, too high temperature or too low temperature will affect its performance, besides self-heating of the equipment, it is also affected by the surrounding environment, usually we will use fans to control the temperature in areas with more suitable temperature The temperature inside the cabinet is adjusted, because the adjustment range of the fan is small, and it only realizes the exchange of the heat flow inside the cabinet and the air outside the cabinet, and cannot achieve the real cooling effect. In areas with harsh environment and high temperature, we Will use a heat exchanger or rack air conditioner to regulate the temperature inside the cabinet

Although heat exchangers and cabinet air conditioners can achieve the effect of cooling, they consume a lot of energy, and the cost is high, and the requirements for the installation size of the cabinet are relatively high.
