Description

technical field [0001] The invention relates to an air conditioning circulation system, in particular to a heat dissipation circulation system of an air conditioning unit. Background technique [0002] At present, the commonly used air-conditioning heat dissipation system uses a tooth-shaped aluminum radiator to closely connect the power module of the outdoor unit of the air conditioner, the drive module of the variable frequency compressor, and the drive module of the variable frequency fan. The heat of the motor drive module and variable frequency fan drive module is dissipated to the outside air by means of air convection and a small amount of natural radiation heat dissipation. [0003] There are following two shortcoming and deficiency in above-mentioned air-conditioning cooling system: [0004] First, the cooling effect in summer is not ideal: especially in some hot summer areas in East China and South China, where the outdoor temperature is high in summer and the air...

Problems solved by technology

[0004] First, the cooling effect in summer is not ideal: especially in some hot summer areas in East China and South China, where the outdoor temperature is high in summer and the air conditioner is frequently used, the power module, inverter compressor drive module, and inverter fan drive module of the air conditioner outdoor unit generate heat Large, due to the high outdoor temperature, it is impossible to reduce the temperature of the toothed aluminum radiator fins below the ambient temperature through air convection (at this time, the ambient temperature near the outdoor unit of the air conditioner is generally 40°C-50°C), resulting in the inability to Fully dissipate the heat generated by the power module, variable frequency compressor driver module, and variable frequency fan driver module of the outdoor unit of the air conditioner, resulting in the power module, variable frequency compressor driver module, and variable frequency fan driver module of the outdoor unit of the air conditioner being unable to guarantee high efficiency and normal operation for a long time In severe cases, it will cause the air conditioner to malfunction, reducing the stability and service life of the air conditioner;

[0005] Second, the heat cannot be recovered and utilized during heating in winter: because the circulation system of the toothed aluminum radiator cannot recover the heat emitted by the power module of the outdoor unit of the air conditioner, the drive module of the variable frequency compressor, and the drive module of the variable frequency fan. waste of energy
