For example, fig. 1 shows an example of an arrangement of these components, the housing 100 may have a first chamber 101 and a second chamber 102 therein, the heat exchanger 103 spans the first chamber 101 and the second chamber 102, the blower 900 is disposed in the first chamber 101, the compressor 104, the control plate 200, the duct cover 300, the air guide 600, the heat pipe 400, and the fin 600 are disposed in the second chamber 102, and these components of the control plate 200, the duct cover 300, the air guide 600, the heat pipe 400, and the fin 600 may be located above the compressor 104.
The fan 900 is configured to accelerate the flow rate of air in the first chamber 101 of the outdoor unit 1, so as to increase the heat exchange efficiency of the heat exchanger 103. Moreover, the heat dissipation air duct 310 is communicated with the first chamber 101, and the air flow rate in the first chamber 101 is increased, so that the air flow rate of the heat dissipation air duct 310 is increased, and the heat dissipation efficiency of the heat pipe 400 is also increased.
The following describes, by way of example, an assembly process of the heat radiating portion of the outdoor unit 1 of the air conditioner according to an embodiment of the present invention.
First, the first heat pipe 410 and the second heat pipe 420 are respectively pressed into the U-shaped groove and the L-shaped groove of the heat conductive mounting plate 700 by using an extrusion process, and then, a flying surface treatment is performed to increase the contact area between the first heat pipe 410 and the second heat pipe 420. The fins 600 are then strung and tightened to ensure good contact.
Then, the heat conducting mounting plate 700 is mounted to the control board 200 by screws, and then the assembled whole components are placed inside the electronic control box 800 and fixed by screws after being mounted in place.
Finally, the air duct cover plate 300 is covered and fixed at the corresponding position.
Other configurations of the outdoor unit 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
For example, an air conditioner including an air conditioner outdoor unit of the present application 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 of the air conditioner or the outdoor unit of the air conditioner.
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.
