Detailed Description
The present invention is specifically described below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.
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 air conditioner includes an outdoor air conditioner, which is a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, and an indoor air conditioner including an indoor heat exchanger, and an expansion valve may be provided in the indoor air conditioner or the outdoor 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.
The indoor air conditioner is connected to an outdoor air conditioner installed in an outdoor space through a pipe. The outdoor unit of the air conditioner may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like of a refrigeration cycle, and the indoor unit of the air conditioner may be provided with an indoor heat exchanger and an indoor fan.
Referring to fig. 1 to 8, the outdoor unit of an air conditioner has an outdoor housing 7, and a partition 8 is provided in the outdoor housing 7, and the partition 8 partitions an inner space of the outdoor housing 7 into a first inner space 5 and a second inner space 6.
The first inner space 5 is provided with an outdoor heat exchanger 1, the front side of the outdoor heat exchanger 1 is provided with a motor 3, an outdoor fan 2 is arranged on the front side of the outdoor heat exchanger 1 along a first direction, and the air outlet direction of the outdoor fan 2 is the same as the first direction. The motor 3 rotates to drive the outdoor fan 2 to rotate, so that the first internal space 5 forms a negative pressure region, and the negative pressure region causes the outside air of the outdoor housing 7 to be sucked into the first internal space 5 through the outdoor heat exchanger 1 and then blown out to the outside. When the outdoor air is sucked, the outdoor air carries away the heat at the outdoor heat exchanger 1 to finish heat exchange, and then the hot air after heat exchange is blown out to the outdoor so as to achieve the effect of reducing the temperature of the outdoor heat exchanger 1.
The second internal space 6 is provided therein with not only refrigeration cycle components such as a compressor and an expander but also components such as an electric box, an electric box holder, and a radiator. The electric appliance box support is provided with a hook, the electric appliance box support is hung on the partition plate 8 through the hook, and then the electric appliance box support is fastened through a screw.
The periphery of the outdoor heat exchanger 1 is provided with a cooling wall 4, i.e., the rear side of the outdoor heat exchanger is provided with the cooling wall 4, so that the outside air of the outdoor case 7 must pass through the cooling wall 4 before passing through the outdoor heat exchanger 1.
According to the utility model discloses an outdoor unit of air conditioner is equipped with a plurality of perforating holes 41 on the cooling wall 4, and outdoor air flows to first inner space 5 through perforating hole 41 and outdoor heat exchanger 1 in. The two ends of the through hole 41 are respectively an air inlet end 411 and an air outlet end 412, wherein the sectional area of the air inlet end 411 of the through hole 41 is larger than the sectional area of the air outlet end 412 of the through hole 41, so that the outdoor air passes through the tightened sectional channel of the through hole 41 and is then released into the first internal space 5.
It can be understood that, since the airflow of the outdoor air is compressed, the airflow can absorb the ambient heat after being released into the first inner space 5, so as to reduce the temperature, and thus the temperature of the outdoor heat exchanger 1 is reduced, and the heat exchange efficiency of the outdoor heat exchanger 1 is improved.
In some embodiments, the plurality of through holes 41 are arranged in the cooling wall 4 in a horizontal and vertical manner. The through hole 41 further includes a transition section 413, and the air inlet end 411 of the through hole 41 is connected to the air outlet end 412 of the through hole 41 through the transition section 413. The transition section 413 is arranged in a funnel shape, when outdoor air passes through the transition section 413 of the through hole 41, the air circulation area of the transition section 413 is gradually reduced, so that the outdoor air can absorb heat around when being released after passing through a gradually reduced cross-section channel, the temperature of the outdoor heat exchanger 1 is reduced, the heat exchange efficiency of the outdoor heat exchanger 1 is improved, and the effects of energy conservation and emission reduction are achieved while the cost is reduced.
In some embodiments, the air inlet ends 411 of the through holes 41 are rectangular holes, and the air inlet ends 411 of the adjacent through holes 41 are tightly connected through the rectangular holes arranged in the transverse direction and the longitudinal direction, that is, no gap exists between the adjacent through holes 41, which is beneficial to increasing the air inlet amount of the outdoor unit of the air conditioner and improving the air inlet and heat exchange efficiency.
Furthermore, the air outlet end 412 of the through hole 41 is a circular hole, the air outlet flow is more stable due to the circular hole, the air outlet flow uniformly flows through the outdoor heat exchanger 1, the problem that the local air flow on the outdoor heat exchanger 1 is different is solved, and the problem that the local heat dissipation efficiency of the outdoor heat exchanger 1 is uneven is solved.
In some embodiments, the left side of the outdoor heat exchanger 1 and the right side of the outdoor heat exchanger are both provided with the cooling walls 4, that is, the periphery of the outdoor heat exchanger 1 is both provided with the cooling walls 4, which is beneficial to improving the heat exchange efficiency of the outdoor unit of the air conditioner, reducing the cost, and achieving the effects of energy conservation and emission reduction.
