[0001] The utility model relates to horizontal energy storage liquid cooling air conditioning technical field, especially horizontal energy storage liquid cooling air conditioning's fan fixed structure of a kind of. BACKGROUND

[0002] In the field of horizontal energy storage liquid cooling air conditioning, with the continuous development of technology, the compactness of internal structure and the rationality of each component layout are increasingly improved. Among them, the fan as a key component to realize air circulation and heat exchange in air conditioning system, the design of its fixed structure is crucial.

[0003] The traditional fan fixing mode usually relies on screws or nuts for fastening connection. In the conventional case layout, when the fan needs to be installed, there is enough operating space to use tools to tighten the screws or nuts, so as to firmly fix the fan at the specified position in the case.

[0004] However, for horizontal energy storage liquid cooling air conditioner, the space inside the case is extremely compact. After the micro-channel heat exchanger is installed, the remaining space inside the case becomes extremely limited. The micro-channel heat exchanger itself occupies a large space volume, resulting in almost no enough space to use conventional tools (such as screwdriver, wrench, etc.) to tighten the screws or nuts near the fan installation position. In this case, if the traditional fan fixing method is still used, many difficulties will be faced. On the one hand, when installing the fan, due to the narrow space, it is difficult to accurately place the tool at the screw or nut position and perform effective operation, which not only greatly increases the installation difficulty and time cost, but also may cause the installation to be not firm, affecting the normal operation of the fan and the performance and stability of the whole air conditioning system. On the other hand, in the subsequent maintenance and repair work, when the fan needs to be disassembled or re-fixed, it is also impossible to smoothly operate due to space limitation, which brings great inconvenience to the maintenance and repair of the equipment, and even the whole case internal structure may need to be partially disassembled to complete the maintenance work of the fan, which undoubtedly increases the downtime of the equipment, reduces the use efficiency of the equipment, and also increases the maintenance cost.

[0005] It can be seen that the prior art needs to be improved and improved. UTILITY MODEL CONTENT

[0006] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a fan fixing structure of horizontal energy storage liquid cooling air conditioner, which aims to fix the fan on the plate frame and the plate frame by means of clamping and docking.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] The fan fixing structure of the horizontal energy storage liquid cooling air conditioner comprises a machine box with an upper opening, a plate frame vertically installed in the machine box, the plate frame comprising a vertical plate, a lower flange arranged at the back of the vertical plate, an upper flange and two side flanges; at least one air suction port is formed in the vertical plate, and the front end surface of the vertical plate is provided with fan assemblies corresponding to the number of air suction ports; at least two U-shaped clamping positions are formed in the upper edge of the lower flange, and vertical limiting screws corresponding to the number of U-shaped clamping positions are welded on the inner bottom wall of the machine box; the lower flange is pressed against the inner bottom wall of the machine box, and the limiting screws are clamped into the U-shaped clamping positions, and the heads of the limiting screws limit the plate frame from being separated from the machine box.

[0009] As a further improvement of the above technical solution, two threaded holes are formed in each of the side flanges, and mounting holes corresponding to the threaded holes are formed in the side surface of the machine box, and fixed screws are connected with the corresponding threaded holes after penetrating through the mounting holes.

[0010] As a further improvement of the above technical solution, the fan assembly comprises a door-shaped frame fixed on the front end surface of the vertical plate and a fan arranged on the door-shaped frame and facing the air suction port.

[0011] As a further improvement of the above technical solution, the front end surface of the vertical plate is provided with a wind guide ring at the air suction port.

[0012] As a further improvement of the above technical solution, a hollow hole is formed in the door-shaped frame.

[0013] As a further improvement of the above technical solution, the vertical plate extends in the transverse direction, the air suction port and the fan assembly are each provided with three, and the fan assemblies are arranged in the transverse direction.

DETAILED DESCRIPTION

[0020] The utility model provides a horizontal energy storage liquid cooling air conditioner's fan fixed structure, to make the utility model discloses the purpose, technical scheme and effect more clearly, definite, the following with the drawings and take example for further detailed explanation of the utility model. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the protection scope of the utility model.

[0021] Please refer to Figures 1 to 3 The utility model provides a horizontal energy storage liquid cooling air conditioner's fan fixed structure, including the cabinet 1 with upper opening, vertical plate frame 2 installed in the cabinet 1, the plate frame 2 includes vertical plate 21, set up lower flange 22 behind vertical plate 21, upper flange 23 and two side flanges 24, the vertical plate 21 is opened and is equipped with at least one exhaust port 25, the front end surface of vertical plate 21 is equipped with the same number of fan assembly 3 with exhaust port 25 and one-to-one correspondence, the rear edge of lower flange 22 is opened and is equipped with at least two U-shaped clamping position 26, the inner bottom wall of cabinet 1 is welded with the limit screw of vertical extension and the same number of U-shaped clamping position 26, lower flange 22 is pressed on the inner bottom wall of cabinet 1 and limit screw is inserted into U-shaped clamping position 26, and the head of limit screw limits plate frame 2 to separate from cabinet 1.

[0022] When the fan fixed structure of horizontal energy storage liquid cooling air conditioner is assembled, the fan assembly 3 is pre-installed on the plate frame 2, and a separate module is formed. Then, the lower flange 22 of the plate frame 2 is placed on the inner bottom wall of the cabinet 1, and the vertical limit screw welded on the inner bottom wall of the cabinet 1 is accurately aligned with the U-shaped clamping position opened on the rear edge of the lower flange 22. Then, the entire plate frame 2 is translated in the rear direction, and in this process, the limit screw is smoothly inserted into the U-shaped clamping position. Due to the blocking effect of the head of the limit screw, the plate frame 2 is effectively limited and cannot be separated upward from the cabinet 1, thereby achieving stable fixation of the plate frame 2 inside the cabinet 1. After installation is complete, the fan assembly 3 is oriented towards the micro-channel heat exchanger 6, and once the fan assembly 3 starts to operate, it can efficiently remove the air around the micro-channel heat exchanger 6 that has absorbed heat, promoting rapid condensation of the refrigerant inside the micro-channel heat exchanger 6.

[0023] In view of the extremely compact space condition inside the horizontal energy storage liquid-cooled air conditioner cabinet 1 due to the presence of the micro-channel heat exchanger 6, the fan fixing structure provided by the utility model skillfully avoids the problem of inconvenient tool operation in a narrow space in the traditional screw or nut fastening mode. With the cooperation mechanism of the U-shaped clamping of the lower flange 22 and the limiting screw, it is not necessary to fiddle with screwdrivers, wrenches and other tools in a cramped space to tighten the screws and nuts, greatly simplifying the assembly process and reducing the requirement for operating space.

[0024] Further, two threaded holes 27 are formed on each of the side flanges 24, and mounting holes 11 corresponding to the threaded holes 27 are formed on the side surface of the cabinet 1, and the fixing screws 12 are connected with the corresponding threaded holes 27 after passing through the mounting holes 11. By further fixing the plate frame 2 from the side, and cooperating with the fixing mode of the lower flange 22 through the limiting screw, a multi-directional stable connection system is formed, which effectively prevents the plate frame 2 from being displaced or shaken in the cabinet 1, greatly enhances the stability of the whole fan fixing structure, ensures that the fan 32 is always in a stable and reliable state during operation, and further ensures the stable operation of the whole horizontal energy storage liquid-cooled air conditioning system.

[0025] Specifically, the fan assembly 3 includes a door-shaped frame 31 fixed on the front end surface of the vertical plate 21, and a fan 32 arranged on the door-shaped frame 31 and facing the air suction port 25. The design of the door-shaped frame 31 provides a stable and specially customized mounting carrier for the fan 32, so that it can be accurately and firmly fixed on the front end surface of the vertical plate 21, effectively utilizing the space structure of the vertical plate 21, ensuring that the fan 32 will not be easily displaced or shaken during operation, ensuring the stability and reliability of the fan 32 operation, and further helping to improve the heat exchange efficiency and performance of the whole horizontal energy storage liquid-cooled air conditioning system.

[0026] In addition, the fan 32 is arranged on the door-shaped frame 31 and faces the air suction port 25, which can make the airflow generated by the fan 32 more concentrated and effectively pass through the air suction port 25 to fully exchange heat with the micro-channel heat exchanger 6. The efficiency of the fan 32 in extracting air is improved, so that the air around the micro-channel heat exchanger 6 that has absorbed heat can be extracted more quickly and in larger quantities, promoting efficient condensation of the refrigerant in the micro-channel heat exchanger 6, enhancing the overall heat exchange capacity of the air conditioning system and improving the refrigeration or heating effect.

[0027] Preferably, the front end surface of the vertical plate 21 is provided with an air guide ring 4 at the air suction port 25. The air guide ring 4 can effectively guide the air flow through the air suction port 25, making the air flow more smooth and concentrated to the fan 32, reducing air flow turbulence and energy loss, improving the air extraction efficiency of the fan 32, and thus improving the heat exchange performance of the entire air conditioning system. By reasonably guiding the air flow, the turbulent noise and impact noise caused by irregular flow of air at the air suction port 25 can be avoided, making the air conditioning system run more quietly, reducing the noise interference to the surrounding environment, and improving the comfort and environmental friendliness of the equipment.

[0028] Further, the door-shaped frame 31 is provided with a hollow hole 33, which can effectively reduce the material usage of the door-shaped frame 31, thereby significantly reducing the weight of the door-shaped frame 31. On the other hand, when the fan 32 is running, the air flow can be divided and redistributed through the hollow hole 33. Part of the air flow can directly pass through the hollow hole 33 and mix with the main air flow entering from the air suction port 25, so that the air flow field around the fan 32 is more uniform and stable, avoiding the influence of local air flow on heat exchange efficiency, and further improving the overall heat exchange performance of the air conditioning system.

[0029] Preferably, the vertical plate 21 extends in the transverse direction, and the air suction port 25 and the fan assembly 3 are each provided with three, and the fan assemblies 3 are arranged in the transverse direction. The arrangement of three air suction ports 25 and fan assemblies 3 arranged in the transverse direction can make the air extraction and circulation in the cabinet 1 more uniform and comprehensive. The fan assemblies 3 at different positions work cooperatively to cover a larger heat exchange area, ensuring that the air around each part of the cabinet 1, especially the micro-channel heat exchanger 6, can be effectively circulated and exchanged, avoiding local heat exchange dead angles, thereby significantly improving the heat exchange uniformity and efficiency of the entire horizontal energy storage liquid cooling air conditioning system, and making the air conditioning system better meet the heat dissipation needs of the energy storage equipment and ensure stable operation.

[0030] Further, the vertical plate 21 is provided with a wire hole, and the wire hole is provided with a wire protection ring 5. The wire protection ring 5 can effectively prevent the cable from being scratched and worn by the hole wall when passing through the wire hole, avoid the damage of the cable insulation layer causing short circuit, electric leakage and other electrical faults, ensure the integrity and safety of the electrical circuit, prolong the service life of the cable, reduce the risk of equipment failure caused by cable damage, and ensure the stable operation of the horizontal energy storage liquid cooling air conditioning system.
