And heat conduction mounting panel 600 has the heat conduction function, and heat conduction mounting panel 600 can be aluminum plate for example, has good heat conductivity and structural strength, so, has increased heat transfer area to improve heat conduction efficiency, make thermal transmission more even.
Further, as shown in fig. 3, the surface of the heat conductive mounting plate 600 facing the compressor 200 is configured with a first pipe groove 610, and at least a portion of the evaporation portion 410 is fitted to the first pipe groove 610. The surface of the heat conductive mounting plate 600 facing the reservoir 300 is configured with a second pipe groove 620, and at least a portion of the condensation part 420 is fitted to the second pipe groove 620.
For example, the first pipe groove 610 and the second pipe groove 620 may have a circular cross section, the first pipe groove 610 is adapted to the outer contour of the evaporation portion 410, the second pipe groove 620 is adapted to the outer contour of the condensation portion 420, and the heat pipe 400 is press-fitted into the first pipe groove 610 and the second pipe groove 620 of the heat conductive mounting plate 600 by using a rolling process. Therefore, the position of the heat pipe 400 and the heat conductive mounting plate 600 is more stable, the first pipe groove 610 and the evaporation part 410 have a larger contact area, and the heat transfer efficiency is higher. Similarly, the second pipe groove 620 has a larger contact area with the condensing portion 420, and the condensing portion 420 is adjacent to the side of the accumulator 300, so that heat of the condensing portion 420 can be transferred to the accumulator 300 more quickly, and the heat transfer speed between the compressor 200 and the accumulator 300 is increased.
In some embodiments of the present invention, as shown in fig. 2 and 3, the heat conducting mounting plate 600 includes a first heat conducting mounting plate 601 and a second heat conducting mounting plate 602.

Specifically, the surface of the first heat conduction mounting plate 601 contacting the compressor 200 and the surface of the second heat conduction mounting plate 602 contacting the accumulator 300 are configured to be arc surfaces to adapt to the installation of the compressor 200 and the accumulator 300, the compressor 200 and the accumulator 300 can be always located in the compressor fixing space 603 and the accumulator fixing space 604, and the assembly of the compressor 200 and the accumulator 300 is firmer. And the first heat conduction mounting plate 601 and the second heat conduction mounting plate 602 are clasped with the compressor 200 and the liquid storage device 300, and the heat conduction mounting plate 600 has a larger heat conduction area with the outer peripheral surfaces of the compressor 200 and the liquid storage device 300, so that the heat conduction of the compressor 200 and the liquid storage device 300 is more sufficient.
Further, as shown in fig. 2 and 3, each of the first heat-conducting mounting plate 601 and the second heat-conducting mounting plate 602 includes a compressor heat-conducting portion 630, an accumulator heat-conducting portion 640, and an intermediate heat-conducting portion 650 connected between the compressor heat-conducting portion 630 and the accumulator heat-conducting portion 640.
By providing the compressor heat-transfer portion 630, heat of the compressor 200 can be rapidly transferred to the evaporation portion 410. By providing the reservoir heat-conducting portion 640, the heat of the condensing portion 420 can be quickly transferred to the reservoir 300. The intermediate heat-transfer portion 650 connects the compressor heat-transfer portion 630 and the accumulator heat-transfer portion 640, improving the structural strength of the heat-transfer mounting plate 600 and increasing the heat-transfer paths.

In some embodiments of the present invention, as shown in fig. 2, the surface of the evaporation part 410 facing the compressor 200 is configured with a first concave surface 411, and the first concave surface 411 is attached to the outer circumferential surface of the compressor 200. A second concave surface 421 is formed on the surface of the condensation portion 420 facing the reservoir 300, and the second concave surface 421 is fitted to the outer peripheral surface of the reservoir 300.
For example, the heat pipe 400 forms the first concave surface 411 and the second concave surface 421 by flying surface processing, and the first concave surface 411 has a larger heat exchange area with the outer peripheral surface of the compressor 200, which is beneficial for the evaporation part 410 to absorb heat generated by the compressor 200. The second concave 421 has a larger heat exchange area with the outer peripheral surface of the liquid reservoir 300, so that the condensing portion 420 can transfer heat to the liquid reservoir 300, and the efficiency of transferring heat from the compressor 200 to the liquid reservoir 300 is improved.
In some embodiments of the present invention, as shown in fig. 2, the evaporation portion 410 extends in the axial direction of the compressor 200. The condensation part 420 and the heating rod 500 extend in the axial direction of the reservoir 300.
Accordingly, heat at various positions in the axial direction of compressor 200 can be transferred to evaporation unit 410, and evaporation unit 410 cools compressor 200 more uniformly. The condensation part 420 can sufficiently transfer heat to the accumulator 300, so that the refrigerant in the accumulator 300 uniformly absorbs heat. Meanwhile, the heating rod 500 generates heat and can be transmitted to all parts of the axial direction of the liquid storage device 300, the refrigerant in the liquid storage device 300 is heated, and the return air temperature of the compressor 200 is increased.
In some embodiments of the present invention, as shown in FIG. 2, heat pipe 400 further includes a middle portion 430.
The intermediate portion 430 is connected between the evaporation portion 410 and the condensation portion 420, and the height of the intermediate portion 430 is gradually decreased in a direction from the condensation portion 420 to the evaporation portion 410.

Other configurations of the outdoor unit 1 of the air conditioner according to the embodiment of the present invention, such as the outdoor heat exchanger 800 and the indoor heat exchanger 700, and operations thereof, are known to those skilled in the art and will not be described in detail herein.
For example, with the air conditioner of the air conditioning outdoor unit 1 in the present application, a refrigeration cycle is performed by using the compressor 200, the condenser, the expansion valve, and the 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 200 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 200. 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 conditioning outdoor unit 1 is an outdoor unit of an air conditioner, that is, a portion of a refrigeration cycle including a compressor 200 and an outdoor heat exchanger, an indoor unit 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 outdoor heat exchanger is used as a heater for a heating mode, and when the indoor heat exchanger is used as an evaporator, the outdoor heat exchanger is used as a cooler for a cooling mode.
