Electric control box assembly of air conditioner

Abstract

The present invention proposes an electric control box assembly of an air conditioner, including a box body; a cover plate, which is closed on the rear of the box body to form a first accommodating space with a first air inlet and a first air outlet with the box body ; The cover body, the cover body is connected with the side wall of the box body, and forms a hollow second accommodating space with a second air inlet and a second air outlet. Therefore, according to the electric control box assembly of the air conditioner in the embodiment of the present invention, by providing the first accommodating space and the second accommodating space, a sufficient installation space is provided for the electrical components, which not only ensures a sufficient distance between the electrical components , and is conducive to the expansion of the function of the air conditioner. In addition, the electric control box assembly in the embodiment of the present invention has a simple structure and is easy to assemble.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an electric control box assembly of an air conditioner. Background technique [0002] The electrical control box assembly of a traditional air conditioner defines an accommodating cavity, and all electrical components are contained in the accommodating cavity. With the rapid development of frequency conversion air conditioner technology, there is a higher demand for unit functionality, so the types and quantities of electrical components may increase; on the other hand, cost pressures are increasing, and under the same capacity conditions, the new generation of air conditioners will be miniaturized As a result of the development, the electric control box of the air conditioner will inevitably develop towards a miniaturized design, and the volume of the electrical component accommodating cavity will be reduced simultaneously. [0003] If the additional electrical compone...

Problems solved by technology

[0003] If the additional electrical components are forcibly installed in the original accommodating cavity, the distance between the electrical components in the accommodating cavity of the electric control box will be reduced, which will adversely affect the electrical function and heat dissipation efficiency in the cavity of the electric control box, especially the harsh Under working conditions, the operating current of the unit increases, the power increases, the electromagnetic interference increases, and the heat generated by the electrical components rises sharply. If the electrical components in the electric control box are not effectively dissipated in time, the reliability and service life of the components themselves will be damaged. It will have a great impact, and in severe cases, it will cause component failure, unit damage and even safety accidents

[0004] At the same time, the reduction in the spacing of electrical components will inevitably reduce production efficiency

Therefore, the existing design of the electric control box accommodating cavity can no longer meet the development requirements of the above two aspects

[0005] In addition, the waterproof effect of the existing electric control box is not ideal, and there is a hidden danger of short circuit of electrical components
