The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant 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.

Referring to FIGS. 1-10 , the air conditioner according to the embodiment of the present application includes: a casing 1 constituting the shell of the air conditioner, and an evaporation unit 2 and a condensation unit 3 arranged up and down.

The air conditioner of the present invention is mainly installed in the equipment cabinet 100. Under the long-term operation of the equipment cabinet 100, there is a problem of a large amount of heat generated by the internal electrical components. The air conditioner in the embodiment of the application can be applied to the heat dissipation requirements of the outdoor equipment cabinet 100 on the base station. , that is, the air conditioner in the embodiment of the present application can effectively dissipate heat from the internal space of the equipment cabinet 100 .

The casing 1 is installed in the inner space of the equipment cabinet 100, and a plurality of components constituting the refrigeration cycle are installed in the casing 1, and the casing defines the overall appearance of the air conditioner, including the side surface of the casing 1 defining the side structure, defining the bottom The bottom surface of the housing 1 of the configuration defines the top surface of the housing 1 of the top configuration. The housing 1 in this application only constitutes the outer shell of the air conditioner, not the inner frame of the air conditioner.

The housing 1 constitutes the shell of the air conditioner, and the housing 1 is provided with an evaporating unit 2 and a condensing unit 3, and the evaporating unit 2 and the condensing unit 3 are arranged up and down in the housing 1, specifically, the evaporating unit 2 is arranged on the condensing unit 3 above.

Electrical components cool down. Fins are provided around the evaporator 21 to increase the contact space between the evaporator 21 and the air, thereby improving the heat exchange efficiency of the evaporator 21 .

During the cooling process of the air conditioner, the water vapor in the air passes through the evaporator 21, and the refrigerant in the evaporator 21 absorbs the heat in the water vapor, causing the water vapor to release heat and condense into water droplets at the evaporator 21, and then merge into condensation Water, the condensed water on the evaporator 21 can flow down along the fins arranged around the evaporator 21 .

A condenser 31 is arranged in the condensing unit 3, and the condenser 31 is arranged under the evaporator 21 of the evaporating unit 2, and in the direction from the evaporating unit 2 to the condensing unit 3, the condenser 31 and the evaporator 21 are overlapped or intersected. , that is, when the condensing unit 3 is viewed from above the evaporating unit 2 , the condenser 31 overlaps or intersects with the evaporator 21 .

In this embodiment, the condenser 31 is arranged below the evaporator 21, and the two overlap, and the condensed water condensed after heat exchange on the evaporator 21 can flow to the condenser 31 along the fins on the evaporator 21, because The refrigerant in the condenser 31 releases heat and condenses into a liquid phase in the condenser 31 , and the heat is released to the surrounding environment through the condensation process, so that the temperature of the condenser 31 is relatively high. Condensed water flowing onto the condenser 31 can speed up the evaporation of the condensed water. At the same time, during the evaporation process of the condensed water, the condensed water absorbs the heat around the condenser 31, so that the temperature of the condenser 31 is relatively lowered, which is beneficial to further improve the performance of the condenser. 31 heat dissipation efficiency, thereby playing a virtuous circle effect on the heat release of the condenser 31.

The separator 4 is hollowed out so that the condensed water flowing down from the evaporator 21 will drop onto the heat exchanger of the condensing unit 3 so as to evaporate the condensed water. However, if the hollow gap on the partition 4 is too large, the circulation of the airflow in the evaporating unit 2 and the condensing unit 3 will be affected, and the two airflows will affect each other, resulting in channeling. In this embodiment, in order to eliminate the channeling problem of the air flow between the evaporating unit 2 and the condensing unit 3, insulation cotton is provided in the hollow of the partition 4, and the hollow gaps of the partition 4 are sealed with thermal insulation cotton, thereby ensuring the evaporation The two airflows in the unit 2 and the condensing unit 3 are not short-circuited, which eliminates the cross-flow problem of the two airflows, and further improves the heat exchange efficiency of the air conditioner. At the same time, the insulation cotton has the properties of water absorption and water permeability. The condensed water on the evaporator 21 drops onto the insulation cotton, and then drops on the condenser 31 through the insulation cotton. The condenser 31 located under the thermal insulation cotton has a higher temperature, which can speed up the evaporation of the condensed water on the thermal insulation cotton, and the condensed water dripping on the condenser 31 can be evaporated by the higher temperature condenser 31, avoiding the condensed water directly Problems with dripping onto the bottom surface of the condensing unit 3.

The condensing unit 3 is provided with a second fan mounting plate 32, the second fan mounting plate 32 divides the condensing unit 3 into a condensing air inlet space 33 and a condensing air outlet space 34, the condenser 31 is arranged in the condensing air inlet space 33, and the The air inlet space 33 communicates with the condensing air inlet 13 , that is, the condensing air inlet 13 is disposed on the housing 1 corresponding to the condensing air inlet space 33 . A second fan 35 is arranged in the condensing air outlet space 34, and the second fan 35 is installed on the second fan mounting plate 32, and one or more second fans 35 are arranged side by side on the second fan mounting plate 32. In this embodiment Two second fans 35 are arranged side by side, and a plurality of second fans 35 are arranged corresponding to the same condensing air outlet 14, so that the air circulation between the condensing air inlet space 33 and the condensing air outlet space 34 can only be passed through the second fan 35. The air condensed in the air inlet space 33 is guided into the condensed air outlet space 34 .

In the embodiment of the present invention, the second fan 35 adopts a shaft-end fan, and the second fan 35 rotates to drive the air in the condensed air inlet space 33 to flow into the condensed air outlet space 34, and then discharge it out of the equipment through the condensed air outlet 14, so as to realize The second airflow circulates. The condensing air outlet 14 is an opening in one direction provided on the housing 1, and the opening direction of the condensing air outlet 14 corresponds to the axial direction of the second fan 35, that is, the opening direction of the condensing air outlet 14 is the same as the outlet of the second fan 35. The direction of the wind is corresponding, so that the air with heat is discharged to the outside of the equipment cabinet 100 more conveniently, and the resistance of the housing 1 to the air is reduced, thereby improving the heat dissipation efficiency of the condensing unit 3 .

In this embodiment, the condenser 31 divides the condensation air inlet space 33 into two parts, one part is the condensation air inlet side 331 , and the other part is the condensation air outlet side 332 . The two ends of the condenser 31 are respectively sealed and connected to the housing 1 through the condensing connecting plate 36, so that the air flow on the condensing air inlet side 331 can only flow through the condenser 31 to the condensing air outlet side 332, thereby avoiding the airflow caused by poor sealing. Air leakage affects the heat dissipation efficiency of the condensing unit 3 of the air conditioner.

The condenser 31 is also arranged in a zigzag shape, which is also formed by splicing two straight plate evaporators. The condenser 31 arranged in a zigzag shape has a condenser open end 311 and a condenser closed end 312 .

In the present invention, the installation positions of the compressors 37 are rationally arranged and the installation of the compressors 37 is prevented from causing adverse effects on the heat exchange of the complete machine of the air conditioner. The compressor 37 is arranged in the condensing air inlet side 331 of the condensing unit 3, that is, in the open end 311 of the condenser, and the compressor 37 is arranged at the position before the air passes through the condenser 31 for heat exchange, which can avoid the replacement of the condensing unit 3. Influenced by heat, the internal space of the condensing unit 3 is saved, thereby ensuring the overall cooling and heat exchange efficiency of the air conditioner.

The condenser 31 is arranged below the evaporator 21, and is also arranged in a zigzag shape, and viewed from the direction of the evaporating unit 2 to the condensing unit 3, the condenser 31 and the evaporator 21 are overlapped to make heat exchange on the evaporator 21 The condensed water after condensation can flow to the condenser 31 along the fins on the evaporator 21, which can save the setting of the water receiving box 5 and drainage components, help reduce the size of the air conditioner in the height direction, and optimize the internal space of the air conditioner. The air conditioner can adapt to more assembly environments, and saving the setting of the water receiving box 5 and drainage components is also beneficial to reduce the structural cost of the air conditioner, so as to save costs and improve industrial efficiency.

On the other hand, since the condensed water produced by the evaporator 21 can be completely evaporated by the condenser 31, the condensed water does not have the problem of directly dripping to the bottom surface of the condensing unit 3, so that there is no condensed water produced by the evaporator 21 in this embodiment. The condensed water leaks in the air conditioner, so that the equipment in the equipment cabinet 100 can run more stably and reliably with higher reliability.

Further, the condensing air inlet side 331 is connected to the condensing air inlet 13 , that is, the condensing air inlet 13 is disposed on the housing 1 corresponding to the condensing air inlet side 331 . The air entering the condensing air inlet 13 flows through the condenser 31 through the condensing air inlet side 331 to the condensing air outlet side 332, and then flows to the outside of the equipment cabinet 100 through the condensing air outlet space 34 driven by the second fan 35. The air outside the cabinet 100 continuously enters the condensing unit 3 from the condensing air inlet 13 through the first air circulation, so as to realize heat exchange for the condensing unit 3 and further promote the cooling of the internal space of the equipment cabinet 100 .

In some embodiments of the present invention, when looking from the evaporating unit 2 to the direction of the condensing unit 3, when the condenser 31 intersects with the evaporator 21, the bottom of the evaporator 21 is provided with a water receiving box 5, that is, a water receiving box 5 is set at the bottom of the evaporator 21, the water receiving box 5 is provided with a drain hole, the drain hole is connected to a drain pipe, and the drain pipe passes through the partition plate 4 and the condensation unit 3 to the outside of the shell 1 and the equipment cabinet 100, In order to connect and discharge the condensed water to the outside of the equipment cabinet 100, it can further prevent the condensed water generated on the condenser 31 from overflowing inside the air conditioner, reduce the risk of water leakage in the air conditioner, and make the equipment in the equipment cabinet 100 run more smoothly. Stable and reliable.
