Heat dissipation system for electrical equipment

Abstract

The invention relates to a heat dissipation system for electrical equipment. The system includes an air purification device and a temperature regulation device; the temperature regulation device is installed on the top of the air purification device; and the air purification device includes an inner support metal filter screen, an inner support filter screen base, a splicing type annular filter screen, a splicing type annular filter screen outer cover, and a top connecting base. Beneficial effects of the system are that: the heat dissipation system for the electrical equipment has the characteristics of simple equipment principle, high reliability, strong applicable environment, environmental protection and energy conservation; and the heat dissipation system is installed in an outdoor field control cabinet, the temperature regulation device is a water-cooled temperature regulation device, a design of a heat dissipation mouth is cancelled, while air temperature conditions in the outdoor field control cabinet are improved, the effect of air purification of the outdoor field control cabinet is also achieved, and so, environment inside the cabinet reaches an ideal environment of various precision instruments and electrical equipment, and the system operates stably, is low in failure rate, and provides a strong guarantee for devices connected to the same.

Description

technical field [0001] The invention relates to a cooling system for electrical equipment, which belongs to the field of electrical equipment. Background technique [0002] The control cabinet is to assemble the switchgear, measuring instrument, protective device and auxiliary equipment in the closed or semiclosed metal cabinet or on the screen width according to the requirements of electrical wiring. and the safety of surrounding equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Control cabinets are common electrical equipment. [0003] In the actual production process, ...

AI Technical Summary

Problems solved by technology

[0003] In the actual production process, the temperature of the outdoor on-site control cabinet will rise when it is working. The general on-site control cabinet is equipped with a heat sink, but the heat dissipation method is mostly air-cooled. Since the on-site control cabinet is mostly placed outdoors, it will At this time, the air-cooled heat dissipation device will cause some moisture or rainwater to enter the control cabinet along with the heat dissipation port of the on-site control cabinet, causing damage to the electrical components inside the controller.

Especially for some sophisticated outdoor field control cabinets, environmental factors such as high humidity, high or low temperature, and large dust will cause equipment failures.

The failure of the outdoor field control cabinet will also cause the equipment connected to it to stop working, causing immeasurable and serious losses
