Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an electric control box component and an air conditioner outdoor unit thereof. Background Art

[0002] At present, air conditioners are indispensable equipment in people's lives. Because the air conditioner outdoor unit is placed outdoors, the ambient temperature and its own high-power heat generation are undoubtedly a severe test for the control panel in the air conditioner outdoor unit, although the air conditioner outdoor unit has taken corresponding measures to cool the control panel.

[0003] In a Chinese invention with authorization announcement number CN103940004B, an air conditioner outdoor unit, its electric control box assembly and installation method are disclosed, wherein the electric control box assembly includes: a first sub-electric control box, in which a frequency conversion module and a refrigerant pipe are installed, and heat dissipation paste is evenly filled between the frequency conversion module and the refrigerant pipe; a second sub-electric control box, which is detachably mounted on the first sub-electric control box, and in which a main control board is installed.

[0004] The above patent uses refrigerant heat dissipation to dissipate heat from the main control board in the electric control box. The heat dissipation method is single and has low heat dissipation efficiency. In addition to the above refrigerant heat dissipation method, other air-conditioning outdoor units also use the negative pressure of the air-conditioning outdoor unit to take away the heat absorbed by the radiator. This heat dissipation method also has the above problems, resulting in the air-conditioning outdoor unit being difficult to completely solve the cooling problem of the control board by relying solely on a single heat dissipation method under high ambient temperature conditions.
