Description

Technical Field

[0001] The invention belongs to the technical field of air conditioners, and in particular relates to an electric control box structure which can effectively reduce operating temperature. Background Art

[0002] When the traditional air conditioner is running under high ambient temperature cooling conditions (national standard working conditions 43℃ ​​and above), for the side-blowing model structure, due to the compact structure, the position of the electric control is limited (poor heat dissipation), which leads to the unit being greatly restricted by the electric control components. As the ambient temperature rises, the module temperature of the electric control area will gradually rise (the module temperature is 65-75℃ at an ambient temperature of 35℃, and the module temperature can reach about 90℃ without limiting the compressor frequency at an ambient temperature of 43℃). To ensure the safe operation of the unit, the control logic of the main control board will generally choose to autonomously reduce the compressor operating frequency to reduce the operating current, thereby reducing the module temperature; however, reducing the compressor frequency will cause the unit capacity to decrease, making the unit unable to meet the needs of users in high temperature areas. In order to enhance the local heat dissipation capacity, reduce the module temperature during operation, and ensure the smooth operation of the compressor as much as possible (reduce the amplitude of frequency reduction), the electric control box structure needs to be further designed to ensure the heat dissipation effect of the unit.
