The power components 72 are provided at the upper end of the side plate 10 so as to be in direct or indirect contact with the side plate 10, so that the heat generating power components 72 can be conducted through the side plate 10.

From this, the air current that flows through the wind gap is drained by fan 50 and is passed through heat exchanger 20, and a part of air current blows to curb plate 10, because the area of curb plate 10 is great, and one side that curb plate 10 is close to fan 50 can be blown by the air current through heat exchanger 20, and power components and parts 72 is through being connected with curb plate 10 and carry out heat-conduction, and then can be cooled down, increase the radiating effect of power components and parts 72.

Further, the electronic control assembly 70 includes a circuit board 71, a plurality of power components 72 are fixedly connected to a front surface of the circuit board 71 and electrically connected to the circuit board 71, and the power components 72 are connected to the side plate 10 through a heat conducting member 80. The heat conducting member 80 may be a heat conducting aluminum plate.

As shown in fig. 1 and 2, since the plurality of power components 72 are fixed on the front surface of the circuit board 71, the power components 72 and the circuit board 71 are electrically connected, the power components 72 generate heat during operation, and the circuit board 71 is mounted on the side plate 10 by being connected with the heat conducting member 80. Therefore, the heat conducting member 80 not only can increase the heat dissipation speed of the power component, but also the heat conducting member 80 can fix the power component 72 on the electronic control assembly 70 to the side plate 10.

Optionally, the heat conducting aluminum plate is vertically disposed on the top end of the side plate 10, the circuit board 71 is disposed perpendicular to the side plate 10, and one end of the power component 72 away from the circuit board 71 is connected to the side plate 10 through the heat conducting aluminum plate.

In detail, the heat conductive aluminum plate has a bent flange 81, and the bent flange 81 is attached and fixed to the outer surface of the side plate 10. As shown in the figure, the heat conducting aluminum plate is provided with a bent flange at one side close to the side plate 10, a gap is formed between the downward bent flange 81 and the heat conducting member 80, and the width of the gap in the direction perpendicular to the side plate 10 is in fit connection with the side plate 10. Therefore, the bending flanging 81 of the heat-conducting aluminum plate increases the reliability of connection between the circuit board 71 and the side plate 10, and further increases the stability and safety of connection.

In the embodiment shown in fig. 3, the electric control assembly 70 extends at least partially into the second receiving space 40 and is fixed to the side plate 10. Therefore, on one hand, the connecting area of the electric control assembly 70 and the side plate 10 is increased, and the connecting stability is increased; on the other hand, the contact area between the power element 72 and the side plate 10 is increased, and the heat dissipation efficiency of the power element 72 and the heat transfer efficiency of the side plate 10 are increased, so that the service life of the power element 72 is prolonged.

The capacitors and the power components 72 are distributed on both sides of the circuit board, wherein the power components 72 are on the side close to the side plate 10. Because the power component 72 occupies a smaller space, the heat transfer from the whole circuit board 71 to the side plate 10 is increased, so that the structure of the electronic control assembly 70 is more compact, and the heat conduction effect is improved.

As shown in fig. 3 and 4, the side plate 10 disposed inside the casing is L-shaped, the L-shaped side plate 10 is divided into a first plate body 11 and a second plate body 12, and a certain included angle is formed between the first plate body 11 and the second plate body 12.

Therefore, in order to enhance the heat conduction capability of the heat conduction member 80 or the side plate 10, graphene may be coated on the surface thereof, so as to increase the heat dissipation speed and reduce the influence of high temperature on the operation of the electronic control assembly 70.

The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
