The air in the equipment cabinet enters the evaporator of the air conditioner through the return air port for heat exchange. However, due to the structural problems of the existing evaporator assembly, the evaporator fan sucks the air in the equipment cabinet and immediately blows it to the evaporator and then sends it back into the equipment cabinet. The air in the equipment cabinet stays in the evaporator for an extremely short time, and the air cannot be fully heat exchanged before being sent back into the equipment cabinet by the evaporator fan, resulting in a technical problem of poor cooling effect of the equipment cabinet air conditioner.

[0041] The embodiment of the invention discloses an equipment cabinet base air conditioner, which is used to solve the technical problem that the existing equipment cabinet base air conditioner has a poor refrigeration effect.

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] See also Figures 1 to 7 , an equipment cabinet base air conditioner provided in this embodiment includes:

[0044] Bottom frame 1, condensing assembly 4, evaporating assembly 3, compressor 5 and refrigerant pipeline;

[0045] The condensing component 4, the compressor 5 and the evaporating component 3 are connected via the refrigerant pipeline;

[0046] The condensing assembly 4, the compressor 5 and the evaporating assembly 3 are all installed on the bottom frame 1;

[0047] The evaporation component 3 includes an evaporation fan 302, an evaporator 303 and an evaporation chamber 301;

[0048] The evaporation chamber 301 is installed on the bottom frame 1, the evaporation fan 302 is installed in the evaporation chamber 301, and the air inlet side of the evaporation fan 302 faces upward, the evaporator 303 is located on one side of the evaporation fan 302, and the evaporator 303 is fixed in the evaporation chamber 301 at a preset inclination angle, and the air outlet side of the evaporation fan 302 and the side of the evaporator 303 form a wedge-shaped space 304.

[0049] It should be noted that the evaporation fan 302 in this embodiment is a centrifugal fan, which realizes axial air intake and circumferential air discharge. In addition, the evaporator 303 is fixed in the evaporation chamber 301 at a preset tilt angle. The tilt angle is essentially the angle formed by the evaporator 303 and the bottom surface of the evaporation chamber 301. Preferably, the angle ranges from 30° to 60°.

[0050] The air inlet side of the evaporator fan 302 in this embodiment faces upward, the evaporator 303 is located on one side of the evaporator fan 302, and the evaporator 303 is fixed in the evaporation chamber 301 at a preset tilt angle, and the air outlet side of the evaporator fan 302 and the side of the evaporator 303 form a wedge-shaped space 304. After the air inlet side of the evaporator fan 302 inhales the air of the equipment cabinet, the air is blown into the wedge-shaped space 304, and the air in the wedge-shaped space 304 can fully exchange heat with the evaporator 303, and the air that has fully exchanged heat with the evaporator 303 is then sent into the equipment cabinet. The above design is conducive to cooling the circulating air at the evaporator 303, so that the cooling effect of the air conditioner is better.

[0051] Furthermore, in this embodiment, the air inlet side of the evaporation fan 302 is spaced apart from the top surface of the evaporation chamber 301 by a preset distance.

[0052] It should be noted that, through the above-mentioned design, the air in the equipment cabinet can stay in the evaporation chamber 301 for a longer time, which is also conducive to sufficient heat exchange between the air and the evaporator 303, ensuring a better cooling effect of the air conditioner.

[0053] Furthermore, a sealing elastic member 305 is disposed on the edge of the top surface of the evaporation chamber 301 in this embodiment.

[0054] It should be noted that, in this embodiment, when the cabinet base air conditioner is installed in the bottom space of the cabinet, the top surface of the evaporation chamber 301 needs to be in close contact with the air supply and return ports at the bottom of the cabinet. Therefore, by providing a sealing elastic member 305, the airflow in the cabinet can be prevented from leaking, ensuring that the cold and hot circulation exchange in the cabinet can proceed normally. The sealing elastic member 305 can be a sealing rubber strip or a sealing silicone strip.

[0055] Furthermore, the condensation assembly 4 in this embodiment includes a condensation chamber 401, a condensation fan 402 and a condenser 403;

[0056] The condensation cavity 401 is installed on the bottom frame 1, the bottom surface of the condensation cavity 401 is an open structure, and the top surface of the condensation cavity 401 is provided with a cover plate 4011;

[0057] The condenser 403 is arranged in the condensing cavity 401, the condensing fan 402 is located above the condenser 403, the air inlet side of the condensing fan 402 faces upward, a plurality of mesh holes 4012 are opened on the cover plate 4011 at positions corresponding to the air inlet side of the condensing fan 402, the air inlet side of the condensing fan 402 is close to the mesh holes 4012, and the air outlet side of the condensing fan 402 faces the condenser 403;

[0058] Specifically, the air outlet side of the condensing fan 402 is separated from the condenser 403 by a preset distance.

[0059] The above-mentioned condensing fan 402 is a centrifugal fan, which realizes axial air inlet and circumferential air outlet with high wind pressure.

[0060] It should be noted that the condensing fan 402 and the condenser 403 are placed in a condensing cavity 401 which is spliced ​​with surrounding panels on all sides, so that the airflow enters the equipment cabinet from the rear side of the equipment cabinet, and then enters the air inlet side of the condensing fan 402 from the top surface of the condensing cavity 401, and then under the action of the condensing cavity 401, the airflow can only be discharged from the bottom of the condensing fan through the condenser 403 and then discharged from the condensing cavity 401 (i.e., outside the equipment cabinet). Conventional centrifugal fans can only achieve axial air inlet and circumferential air outlet. Under the premise of ensuring wind pressure, this embodiment optimizes the airflow direction, which can make the airflow blow toward the condenser 403. The air inlet side of the condensing fan 402 is close to the mesh 4012 on the top surface of the condensing cavity 401, and the air outlet side of the condensing fan 402 is separated from the condenser 403 by a preset distance, which is beneficial to the rapid heat dissipation of the condensing heat exchanger and can further improve the cooling effect of the air conditioner.

[0061] Furthermore, a lifting device 2 is installed on the bottom frame 1 , and the lifting device 2 is connected to the evaporation chamber 301 . The lifting device 2 can drive the evaporation chamber 301 to move up and down.

[0062] It should be noted that the evaporation chamber 301 in this embodiment can realize the lifting function under the drive of the lifting device 2. When installing the equipment cabinet base air conditioner into the equipment cabinet, the installer can adjust the height of the evaporation chamber 301 through the lifting device 2, so that the evaporation component 3 can be smoothly pushed into the bottom installation space of the equipment cabinet. Then, the installer controls the lifting device 2 to adjust the evaporation chamber 301 to a suitable height, so that the evaporation chamber 301 is close to the air supply and return outlets at the bottom of the equipment cabinet, thereby completing the installation. Through the above design, the evaporation component 3 can be applied to equipment cabinets with installation spaces of different heights, so that the evaporation component 3 has a wider range of applications. In addition, the evaporation chamber 301 is pressed against the air supply and return outlets at the bottom of the equipment cabinet by the lifting device 2, and a greater wind pressure can be achieved at the same speed of the evaporation fan 302, which is conducive to the cold and hot circulation exchange in the equipment cabinet.

[0063] Furthermore, the bottom frame 1 in this embodiment includes a longitudinal beam 102 and a transverse beam 101;

[0064] The longitudinal beam 102 and the transverse beam 101 are spliced ​​together to form the bottom frame 1;

[0065] It should be noted that the bottom frame 1 in this embodiment is spliced ​​with frame-type beam profiles, which can achieve lower material costs with the same functional effect compared to splicing with plate profiles.

[0066] In addition, a mounting slope 1012 is disposed on the side of the transverse beam 101 , and the mounting slope 1012 gradually slopes upward from the first end of the transverse beam 101 to the second end of the transverse beam 101 .

[0067] The above design is beneficial for installing the air conditioner at the base of the equipment cabinet, because gravity can be used to make the installation structure of the bottom frame 1 and the equipment cabinet more stable, and the entire bottom frame 11 can be locked by only locking one side of the above-mentioned installation slope 1012.

[0068] Furthermore, if Figures 5 to 7 As shown, the lifting device 2 in this embodiment has a variety of structural forms, one of which can be a scissor-type lifting device;

[0069] The scissor-type lifting device comprises a first support arm 202 and a second support arm 203, wherein the middle portion of the first support arm 202 and the middle portion of the second support arm 203 are hinged to each other to form a scissor-like structure, the first top end portion 2021 of the first support arm 202 is hinged to the bottom of the evaporation chamber 301, the second bottom end portion 2032 of the second support arm 203 is hinged to the first end portion of the transverse beam 101, and the first top end portion 2021 of the first support arm 202 and the second bottom end portion 2032 of the second support arm 203 are arranged vertically up and down;

[0070] The first bottom end portion 2022 of the first support arm 202 is hinged with a first hinge shaft 204, and the first hinge shaft 204 is slidably connected to the second end portion of the transverse beam 101. The second top end portion 2031 of the second support arm 203 is hinged with a second hinge shaft, and the second hinge shaft is slidably connected to the bottom of the evaporation chamber 301. The first hinge shaft 204 and the second hinge shaft are arranged vertically up and down.

[0071] The second end of the transverse beam 101 is connected to a driving member, which can drive the first hinge shaft 204 to move along the transverse beam 101 toward the second bottom end 2032 close to the second support arm 203, so that the second hinge shaft moves synchronously toward the first top end 2021 of the first support arm 202, thereby causing the evaporation chamber 301 to move upward in the vertical direction.

[0072] Specifically, Figure 5 and Figure 7 As shown, the above-mentioned driving member is a driving screw 201;

[0073] The driving screw 201 is threadedly connected to the second end of the transverse beam 101, and the tail end of the driving screw 201 conflicts with the outer side surface of the first hinge shaft 204. When the driving screw 201 is driven to move toward the inner direction of the transverse beam 101, the driving screw 201 drives the first hinge shaft 204 to move along the transverse beam 101 toward the second bottom end 2032 close to the second support arm 203, so that the second hinge shaft moves synchronously toward the first top end 2021 of the first support arm 202, thereby causing the evaporation chamber 301 to move upward in the vertical direction.

[0074] It should be noted that the installer can use a screwdriver or other operating tool to screw the drive screw 201 so that the drive screw 201 moves toward the inside of the transverse beam 101 to drive the first hinge shaft 204 to move toward the second bottom end 2032 of the second support arm 203 .

[0075] Furthermore, if Figure 7 As shown, a first sliding groove 1011 is formed at the second end of the transverse beam 101, and the first sliding groove 1011 extends along the length direction of the transverse beam 101;

[0076] A second sliding groove 3011 is provided at the bottom of the evaporation chamber 301. The second sliding groove 3011 is located directly above the first sliding groove 1011, and the extension direction of the second sliding groove 3011 is the same as the extension direction of the first sliding groove 1011.

[0077] The first hinge shaft 204 is slidably connected to the first sliding slot 1011 , and the second hinge shaft is slidably connected to the second sliding slot 3011 .

[0078] It should be noted that by designing the first sliding groove 1011 on the transverse beam 101, the first hinge shaft 204 can be moved smoothly, and the first sliding groove 1011 also limits the first hinge shaft 204, ensuring that the first hinge shaft 204 will not deviate when sliding. Similarly, the second sliding groove 3011 is provided at the bottom of the evaporation chamber 301, the purpose of which is to make the second hinge shaft move smoothly and ensure that the second hinge shaft will not deviate when sliding.

[0079] Optionally, the lifting device 2 in this embodiment may also adopt other structural forms, for example, the lifting device 2 may be a lifting cylinder or a hydraulic cylinder;

[0080] The lifting cylinder or hydraulic cylinder is fixedly mounted on the bottom frame 1 , and the piston rod of the lifting cylinder or hydraulic cylinder is connected to the bottom of the evaporation chamber 301 .

[0081] It should be noted that when the installer needs to lift the evaporation chamber 301 , the installer can directly drive the evaporation chamber 301 to lift by controlling the lifting cylinder or the hydraulic cylinder.

[0082] The above is a detailed introduction to an equipment cabinet base air conditioner provided by the present invention. For a general technician in this field, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
