Abstract

The invention provides an air conditioner. The air conditioner comprises an indoor unit, an outdoor unit and a heat dissipation assembly; the indoor unit comprises an indoor heat exchanger and an indoor expansion valve; the outdoor unit comprises a compressor, a four-way valve, an outdoor heat exchanger, an outdoor expansion valve and an electric control box, and a circuit board is arranged in the electric control box; the indoor expansion valve and the outdoor expansion valve are sequentially arranged between the indoor heat exchanger and the outdoor heat exchanger; the compressor is connected with the indoor heat exchanger and the outdoor heat exchanger through the four-way valve to form a refrigerating loop used for circulating flowing of a refrigerant; a refrigerant runner is formed in the heat dissipation assembly, and connected between the indoor expansion valve and the outdoor expansion valve; and the heat dissipation assembly is used for absorbing heat released by the circuit board through the refrigerant flowing in the refrigerating loop. According to the air conditioner, rapid heat dissipation of the circuit board can be achieved, condensation is reduced, the use reliability of the circuit board is improved, and the operation reliability of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner. Background technique [0002] Air conditioners are household appliances commonly used in people's daily life. Air conditioners are divided into household air conditioners and commercial multi-connected air conditioners. Wherein, the air conditioner usually includes an indoor unit and an outdoor unit, the indoor unit is installed on the indoor side, and the outdoor unit is installed on the outdoor side. [0003] The outdoor unit in the prior art generally includes a casing, and components such as a compressor, a heat exchanger, an outdoor fan, and an electric control box installed in the casing. With the popularity of air conditioners, the upper limit of operating temperature requirements for air conditioners is also getting higher and higher. The scope of use of modern air conditioners is getting wider and wider, and the upper limit of the required ...
