Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a cabinet air conditioner. Background Technology

[0002] Rack air conditioners are temperature and humidity control devices specifically designed for enclosed spaces such as electrical control cabinets, communication equipment, and outdoor base stations. They are mainly used to solve the heat dissipation problem of electronic components and isolate external dust and corrosive gases to ensure stable operation of equipment. The principle of rack air conditioners is the same as that of traditional air conditioners. They transfer heat from inside the cabinet to the outside through the compressor refrigeration cycle while maintaining a constant temperature and humidity environment inside.

[0003] Most current rack-mounted air conditioners are externally mounted on the outside of enclosed spaces such as electrical control cabinets, with the air outlets of the air conditioners connected to the interior of these enclosed spaces. Existing rack-mounted air conditioners are mostly horizontally laid out, resulting in a large size and low space utilization, making them difficult to install in confined spaces and limiting their applicability. Furthermore, the air outlet positions are fixed and cannot be adjusted. If equipment installed inside an enclosed space like an electrical control cabinet blocks the air outlet, cool air cannot quickly and effectively diffuse into the interior of the space, thus affecting heat dissipation. This necessitates changing the installation location, making it inconvenient to use and requiring further improvement. Utility Model Content

[0016] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0017] like Figures 1-3As shown, a rack-mounted air conditioner includes a rack 1 and a main unit 2 located inside the rack 1. The main unit 2 includes a compressor 21 and a condenser 22, an evaporator 23, and an expansion valve (not shown) connected to the compressor 21. The main unit 2 also includes a condenser fan 24 and a blower fan 25 that cooperate with the condenser 22 and the evaporator 23, respectively. The compressor 21 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas and discharges it into the condenser 22. The high-temperature, high-pressure gas releases heat in the condenser 22 and dissipates heat to the outside through the condenser fan 24, thereby converting it into a medium-temperature, high-pressure liquid refrigerant. The liquid refrigerant is depressurized and cooled by the expansion valve (not shown) to become a low-temperature, low-pressure liquid / gas-liquid mixture. The low-temperature, low-pressure refrigerant absorbs heat from the environment in the evaporator 23 and is blown out as cold air by the blower fan 25 before being re-vaporized into a gaseous state and returning to the compressor 21 to continue the cycle. The above principle is the prior art. The features of this utility model are as follows: the cabinet 1 includes a cabinet body, a front baffle 18 vertically fixed to the lower front side of the cabinet body, a rear baffle 14 vertically fixed to the lower rear side of the cabinet body, a partition 15 inclinedly fixed to the upper inside of the cabinet body, a support plate 16 horizontally fixed between the upper edge of the front baffle 18 and the front edge of the partition 15, and an air outlet plate 17 vertically fixed to the front side of the cabinet body and located above the front baffle 18. The partition 15 is arranged with a lower front and a higher rear. The rear edge of the partition 15 is fixed to the top inner wall of the cabinet body, and the lower edge of the air outlet plate 17 is fixed to the upper edge of the front baffle 18. The evaporator 23 is fixed to the top of the support plate 16, and the condenser fan 24 is embedded and fixed in the rear baffle 14 with the air outlet of the condenser fan 24 facing the rear. The air outlet plate 17 has multiple air outlet holes 171, and the location of the multiple air outlet holes 171 forms an air outlet area 172. The air outlet of the blower 25 is set to face forward and is always located within the air outlet area 172. The air outlet plate 17, partition plate 15, support plate 16, top plate 13 and the inner walls of the left and right sides of the cabinet form a cooling chamber 110; The cooling chamber 110 is also equipped with a switching mechanism 3, which includes a seat plate 31 that is vertically fixed between the inner walls of the left and right sides of the cabinet and a cover plate 33 that is fixed at the air outlet of the air supply fan 25. The air supply fan 25 is fixed on the seat plate 31 and can be adjusted to fix its position left and right. The cover plate 33 is movably connected to the inner wall of the air outlet plate 17 so as to have the function of horizontal translation.

[0018] The front outer wall of the cover plate 33 is slidably attached to the inner wall of the air outlet plate 17. An air outlet duct 331 is formed between the front and rear outer walls of the cover plate 33. The end opening of the air outlet duct 331 is arranged to face rearward and surrounds the air outlet of the blower 25.

[0019] The seat plate 31 has a groove-shaped cavity 311 running left and right. The groove-shaped cavity 311 also has a slider 34 that can move left and right along the direction of the groove-shaped cavity 311. The air supply fan 25 is fixed to the front side of the slider 34. The top and bottom of the slider 34 form a stop block 341 that moves upward and downward, respectively. The front outer walls of the two stop blocks 341 slide against the rear outer wall of the seat plate 31. The side of the air supply fan 25 facing the seat plate 31 slides against the front outer wall of the seat plate 31.

[0020] The upper edge of the base plate 31 has a horizontally arranged flange 312 facing the slider 34. The flange 312 has a left-right oriented slot 313. At least one vertically distributed knob screw 35 is also inserted in the slot 313. The threaded end of each knob screw 35 is inserted into a stop block 341 above.

[0021] The front side of the cover plate 33 is also fitted with a sealing ring 36 that is concentrically surrounded around the air outlet of the blower 25. The front side of the sealing ring 36 extends to the front of the cover plate 33 and slides against the inner wall of the air outlet plate 17.

[0022] Two horizontally arranged and symmetrically positioned Z-shaped baffles 32 are fixed on the inner wall of the air outlet plate 17, located on the upper and lower sides of the air outlet area 172. The opposite side of each Z-shaped baffle 32 is spaced a certain distance from the inner wall of the air outlet plate 17 so that a guide groove 37 is formed between each Z-shaped baffle 32 and the air outlet plate 17. The upper and lower edges of the cover plate 33 are slidably inserted into the two guide grooves 37 respectively.

[0023] The cabinet includes two vertically arranged side panels 12 that are symmetrically distributed to the left and right respectively, a top panel 13 that is horizontally fixed between the upper edges of the two side panels 12, and a bottom panel 11 that is horizontally fixed between the lower edges of the two side panels 12. The lower edge of the rear baffle 14 is fixed to the bottom panel 11.

[0024] The condenser 22 is fixed between the rear edges of the two side plates 12 and above the rear baffle 14, and the compressor 21 is fixed to the top of the base plate 11.

[0025] The rear baffle 14, partition 15, support plate 16, air outlet plate 17, front baffle 18 and seat plate 31 are fixed to the inner walls of the two side plates 12 on the left and right sides respectively. The rear edge of the partition 15 and the upper edge of the air outlet plate 17 are fixed to the inner wall of the top plate 13.

[0026] The top plate 13 also has a first inspection hole 131 located above the seat plate 31, and a detachable first inspection cover 111 is fixed at the first inspection hole 131.

[0027] Each of the two side plates 12 is provided with a second inspection hole 121 that is symmetrically distributed with each other, and a detachable second inspection cover 19 is fixed at each second inspection hole 121.

[0028] The cabinet is also fixed with a detachable U-shaped shell 3. The opening of the U-shaped shell 3 faces the air outlet plate 17, and multiple air inlets 31 are opened at the bottom of the U-shaped shell 3.

[0029] Working principle: Install the cabinet 1 on one side of the cabinet that needs heat dissipation and make the side where the air outlet 17 is located communicate with the inside of the cabinet. When the host 2 starts working, it can blow cold air into the inside of the cabinet to cool the equipment installed in the cabinet.

[0030] Due to the different installation positions of the equipment inside the cabinet, some equipment may block the cold air blown out by the air supply fan 25. Therefore, it is necessary to change the position of the air outlet of the air supply fan 25. During operation, first remove the first inspection cover 111, then reach your hand into the cooling chamber 110 through the first inspection hole 131, and then loosen each knob screw 35 in turn. Then, the air supply fan 25 can be moved left and right by the sliding connection between the slider 34 and the slot cavity 311, thereby driving the air outlet of the air supply fan 25 to move left and right within the air outlet area 172, thereby adjusting the lateral position of the air outlet of the air supply fan 25 to avoid the equipment that will block the air outlet. Finally, tighten each knob screw 35 in turn and reinstall the first inspection cover 111.

[0031] During the movement of the blower 25, the cover plate 33 will slide between the two Z-shaped baffles 32, which can not only provide support for the blower 25 to ensure the smoothness of movement, but also ensure that the front side of the sealing ring 36 always slides against the inner wall of the air outlet plate 17 so that the blown cold air is always concentrated and blown outward from the multiple air outlet holes 171 located on the outside of the end opening of the air outlet duct 331, without spreading.

[0032] This utility model adopts a longitudinal staggered layout to minimize the volume, thereby improving space utilization and expanding the scope of application; at the same time, the air outlet position of the air supply fan 25 can be adjusted laterally as needed, so that the blown cold air can avoid equipment pre-installed in enclosed spaces such as electrical control cabinets, thereby enabling the cold air to spread quickly and effectively, thus ensuring the heat dissipation effect and facilitating use.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
