[0031] The heat exchanger 42 and the wet film assembly 41 divide the heat exchange chamber 11 into an air inlet chamber 51 and an air outlet chamber 52 at the front and rear sides; the top of the electric control box 2 is arranged in the air outlet chamber 52; the bottom of the electric control box 2 is arranged in the compression chamber 12;

[0032] The cabinet 1 is provided with an air inlet 7 communicating with the air inlet cavity 51 and an air outlet 61 communicating with the air outlet cavity 52 .

[0033] Specifically, the cabinet air conditioner described in this embodiment is configured such that the wet membrane component 41 and the heat exchanger 42 are stacked and arranged on the same vertical plane, the heat exchanger 42 is arranged on the top of the wet membrane component 41, and the wet membrane component 41 is arranged on the top of the water receiving tray 3. When in use, it will neither affect the humidification effect of the wet membrane component 41 nor add unnecessary resistance to the airflow when passing through the heat exchanger 42 for cooling. At the same time, the top of the wet membrane component 41 can also use the condensed water flowing down from the heat exchanger 42 for humidification, and the coldness of the condensed water is reasonably used for secondary cooling. At the same time, the bottom of the wet membrane component 41 can absorb water from the water receiving tray 3, so that the entire surface of the wet membrane component 41 can be more fully wetted, and the evaporation and humidification effect is better.

[0034] In the cabinet air conditioner described in this embodiment, an axial flow fan 8 installed without a fan bracket is provided in the air outlet cavity 52. ​​Specifically, the axial flow fan 8 capable of generating high static pressure is used in this embodiment to replace the centrifugal fan, which can not only realize the functions of long-distance air delivery and large air volume, but also reduce energy consumption and noise.

[0035] In the cabinet air conditioner described in this embodiment, a variable frequency drive component is provided on the inner side of the top of the electric control box 2; and a heat sink 21 is provided on the outer side of the top of the electric control box 2. Specifically, in this embodiment, by placing the variable frequency drive component with high heat generation on the top of the electric control box 2, the cold air from the air outlet cavity 52 and the heat sink 21 can effectively dissipate heat and cool the electric control box 2 and the variable frequency drive component.

[0036] In the cabinet air conditioner described in this embodiment, the heat sink 21 is extended toward the wet film assembly 41. Through the above arrangement, it is more conducive to cooling and heat dissipation at the heat sink 21 when the air conditioner is humidifying.

[0037] In the cabinet air conditioner described in this embodiment, the cross-sectional shape of the heat exchanger 42 is U-shaped, V-shaped or arc-shaped. Specifically, the above configuration can effectively increase the heat exchange area of ​​the heat exchanger 42, thereby improving the cooling effect of the air conditioner.

[0038] In the cabinet air conditioner described in this embodiment, a front door 6 is provided at the front end of the cabinet 1; the front door 6 is hinged to a side edge of the cabinet 1 and can be rotatably opened; the front door 6, the cabinet 1, the water receiving tray 3, the heat exchanger 42 and the wet film assembly 41 form the air outlet chamber 52; the front door 6, the cabinet 1 and the water receiving tray 3 form the compression chamber 12.

[0039] After the front door 6 is opened, the axial flow fan 8 is fixed on the fan mounting plate, and the fan mounting plate, the side plate of the cabinet 1, the top plate of the cabinet 1, the heat exchanger 42, the wet film assembly 41 and the water receiving tray 3 form the air outlet cavity 52, and the top of the axial flow fan 8 and the electric control box 2 are both located in the air outlet cavity 52;

[0040] The cover plate of the electric control box 2 , the side plates of the cabinet 1 , the bottom plate of the cabinet 1 , the back plate of the cabinet 1 and the water receiving tray 3 form the compression chamber 12 , and the compression assembly 13 and the bottom of the electric control box 2 are located in the compression chamber 12 .

[0041] Specifically, the above arrangement in this embodiment makes it easy for the user to open and close the front door 6, so that the various components in the cabinet air conditioner can be repaired and replaced separately.

[0042] In the cabinet air conditioner described in this embodiment, the front door 6 is provided with a protrusion 62. The protrusion 62 in the middle of the front door 6 can strengthen the strength of the front door 6, because after the large-area air outlet 61 is opened on the front door 6, the metal part is easy to deform, so the middle protrusion structure can prevent deformation, and at the same time, the part protrudes from the plane, which has a strong visual impact from the appearance.

[0043] In the cabinet air conditioner described in this embodiment, the air outlet 61 is arranged on the upper part of the front door 6. The above arrangement facilitates the cabinet air conditioner to discharge air from the front. At the same time, a display screen is also arranged at the center of the air outlet 61 to facilitate human-computer interaction of the cabinet air conditioner.

[0044] In the cabinet air conditioner described in this embodiment, the air inlet 7 is provided with a filter 71. Specifically, the above arrangement can prevent impurities from entering the cabinet air conditioner.

[0045] In the cabinet air conditioner described in this embodiment, the air outlet cavity 52 is provided with an electric heater. Specifically, the above arrangement can perform heat compensation on the air dehumidified by the heat exchanger 42 when the humidity is high.

[0046] In the cabinet air conditioner described in this embodiment, the compression chamber 12 is provided with a compression assembly 13. In this embodiment, the compression assembly 13 is placed in the compression chamber 12, so that the overall structure is neater, and the compression chamber 12 is automatically closed after the front door 6 is closed, which can effectively isolate the operating noise of the compression assembly 13 and prevent the compression assembly 13 from causing wind resistance, thereby reducing the energy consumption of the air conditioner.

[0047] In the cabinet air conditioner described in this embodiment, the air inlet 7 is provided on both sides and / or the back of the cabinet 1; the air inlet 7 is provided at the position of the cabinet 1 corresponding to the wet film assembly 41, so that the filter 71 is removed, which is convenient for directly disassembling and cleaning the wet film assembly 41 inside the cabinet 1, and the air inlet 7 is provided at the position of the cabinet 1 corresponding to the heat exchanger 42, which is convenient for directly repairing the sensors, valves and pipelines at the heat exchanger 42. Specifically, through the above-mentioned arrangement, the airflow is filtered by the filter 71 and enters the air inlet chamber 51 from the air inlet 7 of the cabinet, and then completes heat exchange and humidification through the wet film assembly 41 and the heat exchanger 42, and then flows through the axial flow fan 8 and the front door 6 in sequence, and finally the airflow is blown out from the air outlet 61 directly in front of the cabinet, completing the entire cooling and humidification cycle.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
