Electric control cabinet with excellent refrigerating effect

Abstract

The invention discloses an electric control cabinet with an excellent refrigerating effect. The electric control cabinet comprises an electric box and a refrigerating box, wherein the electric box comprises a box body (1); the box body (1) comprises a first box body (2) and a second box body (3) which are formed through dividing the box body in the middle; a first electric cabinet (4) is arranged in the first box body (2) and is provided with high-voltage components; a second electric cabinet (5) is arranged in the second box body (3) and is provided with low-voltage components; an air outlet and an air inlet are formed in the back surface of each of the first box body (2) and the second box body (3); the refrigerating box comprises a return air channel (6), an air outlet channel (7), an air conditioner (8) and a heat exchanging air channel (9). According to the invention, the air inlet design concept of a refrigeration air conditioner is adopted to enable the electric control cabinet to obtain a better air inlet effect and heat dissipation concept, so that the electric control cabinet is ensured to have a better working environment.

Description

AI Technical Summary

Problems solved by technology

[0003] The existing electric control box is generally equipped with various electrical components such as air switch, relay, contactor, circuit breaker, fuse (fuse), integrated circuit, socket, etc. These control components and connection circuits are customized according to the control requirements of specific equipment. Design, the electric control box of the existing engraving and milling machine is generally integrated, all components are in one box, some of these components are high-voltage components, some are low-voltage components, placed in the same box, high-voltage components Electromagnetic interference will be generated between the device and the low-voltage components, affecting the normal use of the equipment, and even causing damage and failure of some components, making the machine unsafe and reliable during operation

[0004] And because most of the current electric control boxes use small fans to dissipate heat, the internal parts cannot dissipate heat better when they are working.
