Problems solved by technology

This heat dissipation method needs to rely on the external fan to take away the heat, which is greatly affected by environmental problems, and the noise of the external fan is relatively large; moreover, when the inside of the electrical box needs greater heat dissipation, or like some structures without an external fan ( For example, water source heat pump multi-connected unit), forced convection cannot be formed in the unit, and the heat dissipation of the electrical box is undoubtedly a problem

Abstract

The invention discloses an electrical box assembly which comprises an electrical box used for accommodating electrical components, as well as a rear cover and a first fan, wherein at least one first air inlet, at least one first air outlet and at least one window used for allowing a radiator to extend out are formed in the electrical box; at least one second air inlet and at least one second air outlet are formed in the rear cover; the window and the outer side of the first air outlet are covered with the rear cover, and an air duct communicated with the second air inlet and the second air outlet is surrounded by the rear cover and the electrical box; and the first fan is mounted at the second air outlet. According to the electrical box assembly, a double-air-duct design is adopted, the radiating fan is integrated inside the electrical box, and the fan is used for intensively extracting out heat in the electrical box, so that the radiating efficiency of the electrical box is improved, and at the same time, heat radiation of the electrical box is not influenced by the environment and the working condition. The invention further discloses a VRF air-conditioning unit using the electrical box assembly.

Description

technical field [0001] The invention relates to a cabinet for electrical equipment, in particular to an electrical box assembly and a multi-connected air conditioner unit using the electrical box assembly. Background technique [0002] At present, the electrical boxes of multi-connected air-conditioning units are generally made of aluminum heat sinks that are attached to the modules. During operation, the external fan rotates to make the inside of the electrical box form convection and take away the heat of the electrical box to dissipate heat. This heat dissipation method needs to rely on the external fan to take away the heat, which is greatly affected by environmental problems, and the noise of the external fan is relatively large; moreover, when the inside of the electrical box needs greater heat dissipation, or like some structures without an external fan ( For example, water source heat pump multi-connected unit), forced convection cannot be formed in the unit, and the...
