[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] See also Figures 1 to 3 As shown, according to an embodiment of the present application, a cabinet air conditioner heat dissipation component includes:

[0036] The housing 2 includes an outer top cover 21 located outside the cabinet door panel 1;

[0037] The rainwater collecting member 9 is arranged on the outer top cover 21 ; the outer top cover 21 is provided with a water distributor 22 for distributing the rainwater collected by the rainwater collecting member 9 to the heat dissipation member in the shell 2 .

[0038] The present application sets a rainwater collecting part 9 and a water distributor 22 on the outer top cover 21 outside the cabinet door panel 1, which can collect rainwater and dissipate heat for the heat dissipation parts in the cabinet, thereby relatively reducing the operating time of the external fan 7 and extending the service life of the external fan 7.

[0039] If there is no rain, the rated operation of the external fan 7 is maintained to achieve the heat dissipation effect of the heat dissipation component.

[0040] In some embodiments, the water distributor 22 includes a sieve hole provided on the outer top cover 21, and the sieve hole is located directly above the heat element to be cooled.

[0041] Sieve holes are arranged on the heat dissipation part, and the collected rainwater is evenly dispersed by using the sieve holes and dripped onto the heat dissipation part to achieve the effect of uniform cooling. There is no need to set up an additional power mechanism to distribute the rainwater, and the structure is simple.

[0042] The water distributor 22 disposed on the outer top cover 21 has the function of filtering and blocking dead branches and rotten leaves from falling into the unit and distributing rainwater evenly; preferably, a filter mesh assembly is also arranged on the water distributor 22 to prevent dead branches and rotten leaves from clogging the sieve holes of the water distributor 22.

[0043] In some embodiments, the rainwater collecting member 9 is rotatably connected to the outer top cover 21, and when the rainwater collecting member 9 rotates, the sieve holes can be opened or closed.

[0044] The rainwater collecting member 9 is rotatably connected to the outer top cover 21 to realize opening or closing of the sieve holes. In this way, when it rains, the rainwater collecting member 9 collects rainwater to cool the heat dissipation component to be cooled, thereby reducing the operating time of the external fan 7. If there is no rain, the sieve holes are closed to ensure that the airflow driven by the external fan 7 is fully used to cool the heat dissipation component to be cooled.

[0045] In some embodiments, the rainwater collecting member 9 includes a cover plate 91 and a rotating member 92 , one side of the cover plate 91 is connected to the rotating member 92 , and the rotating member 92 is connected to the outer side of the outer top cover 21 .

[0046] The rainwater collecting element 9 can specifically adopt the structure of a cover plate 91 combined with a rotating element 92. The cover plate 91 can be adjusted in angle according to the regulation of the rotating element 92. For example, when the cover plate 91 is unfolded and rotated to be basically flush with the outer top cover 21, it has the largest area for collecting rainwater; it can also be rotated to cover the outer top cover 21, which is equivalent to sealing the water distributor 22, which is the same as the traditional structure; therefore, the rainwater collecting element 9 of the present application can achieve different working states.

[0047] In order to effectively collect rainwater, the outer top cover 21 can be made into a concave shape to prevent rainwater from overflowing and draining from the periphery of the outer top cover 21; when the rotating cover plate 91 is opened to collect rainwater, the two side edges perpendicular to the rotating member 92 are bent upward (the opposite side edges parallel to the rotating member 92 have no folded edges, otherwise they will interfere with the joint between the outer top cover 21 and the door panel 1 when resetting), which is conducive to collecting rainwater; there are several water holes on the axis of the rotating member 92, so that the rainwater collected on the cover plate 91 can flow to the outer top cover 21 through the water holes, and then mix with the rainwater collected by the outer top cover 21 and enter the water distributor 22. Preferably, when the cover plate 91 is reset to the horizontal position where the outer top cover 21 is located, the two side edges of the cover plate 91 (perpendicular to the rotating member 92) can wrap the entire outer top cover 21.

[0048] When the cover plate 91 is in a horizontal position above the outer top cover 21 , the water distributor 22 is blocked by the cover plate 91 and does not have the air circulation function.

[0049] In some embodiments, the rainwater collecting member 9 further includes a driving mechanism capable of driving the rotation of the rotating member 92. Preferably, the rotation angle of the rotating member 92 is set to 0 degrees-270 degrees.

[0050] The rotation of the rotating member 92 can be achieved by a driving mechanism, such as a motor combined with a transmission member such as a gear, so that the cover plate 91 is at different angles. Specifically, the rotation angle of the rotating member 92 is 0 degrees to 270 degrees. When it is at 0 degrees, it covers the outer top cover 21, and when it is at 270 degrees, it blocks the adjacent side of the outer top cover 21. Figure 3 At least part of the tuyere of the condenser 8 shown; Figure 2 As shown, the angle is between 170 degrees and 178 degrees, which expands the area for collecting rainwater.

[0051] The rotating member 92 mentioned above includes but is not limited to a rotating shaft, a gear set, a driving motor, a shaft seat, etc. The design and application of these components belong to conventional structures.

[0052] According to another aspect of the present application, a cabinet air conditioner is provided, comprising the cabinet air conditioner heat dissipation assembly as described above.

[0053] The use of the above heat dissipation component in the cabinet air conditioner can reduce the operating time of the external fan 7 and increase its service life.

[0054] In some embodiments, an external fan 7 and a compressor 6 are provided in the shell 2 and are located outside the cabinet door panel 1. A rain shield is provided above each of the external fan 7 and the compressor 6 to prevent rainwater distributed into the shell 2 by the water distributor 22 from dripping onto the external fan 7 and the compressor 6.

[0055] A relatively closed space is formed inside the cabinet shell 2, and the middle partition 4 separates the condensation chamber from the evaporation chamber. The condenser 8 is located in the outer cavity of the door panel 1. An external fan 7 is provided at the lower part of the condenser 8. A baffle 71 is also arranged between the condenser 8 and the external fan 7 to prevent rain from falling directly on the external fan 7, but the baffle 71 cannot block the airflow from entering the condenser 8; the compressor 6 is usually arranged on the chassis of the outer cavity, and a rain shield 61 is added above the compressor 6 and its accessories to prevent rain from splashing onto the compressor 6 to avoid safety failures or damage to the compressor 6 and its accessories.

[0056] The cavity inside the door panel 1 is at least provided with an electric control box, an internal fan 3 and an evaporator 5. In view of the optimization of the spatial structure, the internal fan 3 is generally provided above the evaporator 5. There is a water receiving pan at the bottom of the evaporator 5, and the water receiving pan and the middle partition 4 are usually provided as an integrated or combined component. The function of the water receiving pan is mainly to receive the low-temperature condensed water discharged from the evaporator 5. Therefore, a drain pipe is designed at the bottom of the water receiving pan, which is connected to the outer cavity. The condensed water is discharged to the chassis through the drain pipe, and then discharged from the drain port arranged on the chassis to the cabinet air conditioner.

[0057] In some embodiments, a condenser 8 is further provided in the shell 2 and is located on the outside of the cabinet door panel 1. The heat dissipation component includes the condenser 8. The condenser 8 is located directly below the water distributor 22. The rainwater collected by the rainwater collecting component 9 drips onto the condenser 8 through the water distributor 22.

[0058] The condenser 8 is directly arranged below the water distributor 22. Rainwater drips directly onto the condenser 8 under the action of gravity, thereby cooling the high-temperature condenser 8, reducing the operating time of the external fan 7, and extending its service life.

[0059] In some embodiments, when the rainwater collecting member 9 includes a rotating member 92 and a cover plate 91 , the cover plate 91 can be rotated through the rotating member 92 to cover at least a portion of the air outlet of the condenser 8 .

[0060] The cover plate 91 can be rotated to the air outlet side of the condenser 8, so that the airflow sent by the external fan 7 can be discharged through the air outlet of the condenser 8, and can also be discharged through the sieve holes of the water distributor 22, which has different effects. When the air outlet is partially covered, it does not affect the cooling of the condenser 8 by raindrops, and the air sent by the external fan 7 simultaneously cools the condenser 8; partial covering can also form a chimney effect. When there is no rain, the airflow backflowing from the air outlet and the airflow from the external fan 7 are discharged from the sieve holes together, which plays a role in cooling the condenser 8. When the air outlet is covered as a whole, it can also play a chimney effect and play a role in cooling the condenser 8.

[0061] According to another aspect of the present application, a control method for the cabinet air conditioner as described above is provided, comprising:

[0062] Detect rain outside the cabinet and adjust the rainwater collecting element 9 to collect rainwater; the rainwater is distributed to the heat dissipation element to be cooled through the water distributor 22 to take away the heat from the heat dissipation element; or,

[0063] The rainwater collecting member 9 includes a rotating member 92 and a cover plate 91. When an external fan 7 and a condenser 8 located outside the cabinet door panel 1 are provided in the shell 2, the temperature outside the cabinet is detected, and when the temperature reaches a preset temperature, the rotating member 92 is adjusted to the cover plate 91 to cover at least part of the air outlet of the condenser 8.

[0064] The control method of the entire cabinet air conditioner includes two situations: rain and low temperature. When it is detected that the outdoor rain is sufficient (how to detect the amount of rain belongs to the detection technology, and this application does not provide too much technical explanation), the rotating member 92 is controlled to rotate a certain angle, such as 170 degrees to 178 degrees, so that the cover plate 91 is extended. At this time, the cover plate 91 and the outer top cover 21 collect rainwater together. After the rainwater is collected, it falls evenly onto the condenser 8 through the water distributor 22. After taking away the waste heat of condensation, the rainwater flows down along the baffle 71 and is finally discharged from the drain port of the chassis.

[0065] At this time, as the refrigerant temperature (and / or pressure, the same below) at the outlet of the condenser 8 decreases, the rotation speed of the external fan 7 is gradually reduced until the external fan 7 is stopped.

[0066] When it is detected that the refrigerant temperature at the outlet of the condenser 8 rises and is not conducive to the operation of the refrigeration system, the rotation speed of the external fan 7 is gradually increased; when the rotation speed of the external fan 7 reaches the rated rotation speed, the cover 91 is closed and the refrigeration system is operated according to the normal refrigeration procedure.

[0067] When it is detected that the outdoor air temperature is low enough, such as T<0deg (the controller has an adjustable limit value built in, such as -10deg to 2deg, which can be adjusted and selected), the rotating member 92 is controlled to rotate vertically downward to block part or all of the air outlet area of ​​the condenser 8, and the speed of the external fan 7 is gradually reduced until the external fan 7 is stopped. When it is detected that the refrigerant temperature at the outlet of the condenser 8 rises and is not conducive to the operation of the refrigeration system, the speed of the external fan 7 is gradually increased; when the speed of the external fan 7 reaches the rated speed, the cover plate 91 is closed, so that the cover plate 91 is reset to the horizontal position above the external top cover 21, and the refrigeration program is operated according to the normal procedure.

[0068] When the speed of the external fan 7 recovers to 80%-85% of the rated speed, the cover plate 91 can be vertically downward to block part or all of the air outlet area of ​​the condenser 8, so that all or part of the air driven by the external fan 7 flows out from the water distributor 22 in the opposite direction. The airflow drives the debris accumulated on the external top cover 21 to leave the external top cover 21 to prevent the water distribution holes of the water distributor 22 from being blocked, which is beneficial to the normal operation next time. After 1 to 2 minutes, the drive motor is started again to restore the rotating cover plate 91 to the horizontal position on the upper part of the external top cover 21.

[0069] When the outdoor air temperature is low enough or it is a continuous rainy season, the chimney effect of cold air can be fully utilized to dissipate heat naturally or the good heat dissipation performance of rainwater. It may not be necessary to turn on the external fan 7 to meet the needs of condensation heat dissipation, which can save fan energy consumption and extend the service life of the fan.

[0070] Based on the structural design of the original integrated cabinet air conditioner, the present application adds a water distributor 22 to the outer top cover 21, and changes the design of the junction between the outer top cover 21 and the outer panel to add a rotating cover plate 91 structure. The cover plate 91 can be in different positions, so that different air duct operation modes can be achieved, and the beneficial effects are as follows:

[0071] When the cover 91 is closed, a normal cooling mode of forced air cooling driven by the external fan 7 is realized;

[0072] The cover plate 91 is unfolded to expand the rainwater collection area, and the collected rainwater is gathered to the water distributor 22 and evenly falls into the condenser 8, realizing water cooling or a mixed cooling mode of "water cooling + air cooling";

[0073] When the cover plate 91 is hung down to block the upper part or all the air outlets of the condenser 8, top air outlet cooling can be achieved or the chimney effect can be used to fully utilize the outdoor cold air for natural heat dissipation mode.

[0074] It is easy for those skilled in the art to understand that the above-mentioned implementation modes can be freely combined and superimposed without conflict.

[0075] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
