[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. 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 creative work are within the scope of protection of this application.

[0025] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] For cooling units, heat exchange components are usually provided to achieve air convection, thereby exporting heat and / or importing cold, so as to achieve cooling and lowering the temperature control environment. Existing heat exchange components usually include a fan module, under the action of the fan module, the convection of air can be accelerated, thereby improving the overall working efficiency of the cooling unit; however, for the cooling unit of a box-type air conditioner, the fan module is usually arranged at the opening at the top or bottom of the cooling unit, and the position of the fan module is relatively fixed. If the heat exchange capacity of the cooling unit is high, then more heat needs to be exported and / or more cold needs to be imported here, so that the purpose of the cooling unit fully cooling the temperature control environment can be achieved. However, since the relative position of the fan module is fixed, in actual applications, after the fan module is installed, the installation position of the heat exchange module in the box cannot be adjusted, which leads to the problem that the local heat in the box is difficult to achieve heat exchange with the external air or refrigerant medium. Based on the above situation, the present application proposes a fan unit with adjustable fan module position, so as to adjust the position of the fan module according to the position of the heat exchange module in the box to improve the working efficiency of the fan module.

[0028] like Figure 1 As shown, in this embodiment, a fan unit is provided, which includes a mounting frame 1 and a fan module 2. The mounting frame 1 is usually arranged at the top or bottom of the cooling unit, that is, the mounting frame 1 is formed on the top or bottom of the cooling unit to facilitate the installation of the fan module 2. The fan module 2 is correspondingly installed at the window 13 of the mounting frame 1, that is, the air outlet of the fan module 2 is aligned with the window 13. In some installations, the fan module 2 needs to pass through the window 13 and cooperate with the window 13.

[0029] When multiple fan modules 2 are provided, multiple windows 13 need to be provided corresponding to the mounting frame 1. When connected, part or all of the frames around the window 13 are connected to the edges corresponding to the fan module 2, thereby completing the installation and maintaining a certain stability of the fan module 2 during operation.

[0030] Furthermore, the fan module 2 includes a mounting plate 21 and a fan body 23. When the fan module 2 is installed in cooperation with the window 13, the edge of the mounting plate 21 is installed in cooperation with the frame of the window 13, that is, the outer contour of the mounting plate 21 can be roughly consistent with or completely consistent with the outer contour of the frame of the window 13, so that the edge portion of the mounting plate 21 can be installed in cooperation with the frame.

[0031] Please refer to Figure 4 An opening 22 is provided on one side of the mounting plate 21, and a fan body 23 is mounted on the mounting plate 21 and corresponds to the position of the opening 22, thereby docking with the fan body 23, so that the fan body 23 has a ventilated wind path, and the fan body 23 is used to accelerate the convection of air on both sides of the fan.

[0032] On the basis of the above embodiment, if the fan module 2 is rotated relative to the corresponding window 13, the position of the fan body 23 will change; in other words, the opening 22 is set to one side, which means that the center or center of the opening 22 does not coincide with the rotation axis of the fan module 2, thereby forming an eccentric opening 22 on the mounting plate 21, so as to achieve the purpose of changing the position of the opening 22 and the fan body 23 by rotation.

[0033] It should be pointed out that after the fan module 2 is rotated by a preset angle, the edge of the mounting plate 21 can still be installed in cooperation with the frame of the window 13. In other words, the position of the fan module 2 in the window 13 can have at least two states, one is before the preset angle is rotated, at which time the edge of the mounting plate 21 can be installed in cooperation with the frame of the window 13; the other is after the preset angle is rotated, the edge of the mounting plate 21 can still be installed in cooperation with the frame. However, it should be noted that the above two states in a window 13 are independent of each other, and the switching between the two states can be achieved by rotation. Of course, the premise of rotation is that the mounting plate 21 and the frame of the window 13 are not in a connected state.

[0034] There are two positional relationships between the edge of the mounting plate 21 and the frame of the window 13, namely, one is that the edge of the mounting plate 21 is embedded in the window 13, or there is a partial connecting structure on the mounting plate 21 embedded in the window 13, at this time, the edge of the mounting plate 21 or the connecting structure corresponds to the frame position of the window 13, and the preset angle of rotation of the fan module 2 will be affected by the edge of the mounting plate 21 and the frame structure of the window 13. The fan module 2 can only make the edge of the mounting plate 21 adapt to the frame of the window 13 after rotating the preset angle, thereby completing the embedded installation; the other is that the mounting plate 21 and the window 13 are in a stacking relationship. At this time, the rotation angle of the fan module 2 is not affected by the mounting plate 21 and the window 13 structure. At this time, the mounting plate 21 and the frame support limit of the window 13, the edge of the mounting plate 21 can be installed relative to any rotation angle position of the frame, and the position of the fan body 23 can also be changed.

[0035] In addition, for a fan module 2 in a window 13, it can include multiple fan bodies 23, that is, multiple openings 22 and fan bodies 23 corresponding to the openings 22 are set on the mounting plate 21. By rotating the fan module 2, the positions of the multiple fan bodies 23 can be adjusted at the same time, thereby realizing simultaneous adjustment of the multiple fan bodies 23.

[0036] There can be many forms of fixed connection between the mounting plate 21 and the window 13 frame, such as screws, bolts, snap-on devices, plug-in devices or other connecting devices, but it is necessary to ensure the sealing fit, position stability and gravity support of the mounting plate 21 and the window 13 frame when they are installed in coordination.

[0037] In summary of the above embodiments, the present application sets an opening 22 biased to one side on the mounting plate 21, and the fan body 23 is installed at the corresponding position of the opening 22, so that after the fan module 2 rotates a preset angle, the position of the fan body 23 relative to the corresponding window 13 changes to adjust the position of the air inlet and the air outlet of the fan module 2, so as to arrange the air inlet and the air outlet of the fan module 2 at the actually required position according to the actual on-site needs, so as to improve the working efficiency of the fan module 2.

[0038] In the embodiment, the edge of the mounting plate 21 is embedded in the window 13 as an example for description. The window 13 may be a square window, so the mounting plate 21 is naturally a square plate that matches the shape of the window 13. Under this premise, if the window 13 is a square window and the mounting plate 21 is adapted to be arranged therewith, then the above-mentioned preset angle may be 90°, that is, after the fan module 2 is rotated 90°, the mounting plate 21 can be installed again in coordination with the square structure of the window 13, and at this time, the position of the fan body 23 will be dislocated compared to the original position; if the preset angle is continued to be rotated, the fan body 23 will be dislocated again, thereby realizing multi-position adjustment of the fan body 23.

[0039] If the window 13 is a rectangular window and the mounting plate 21 is adapted thereto, then the preset angle may be 180°, i.e., after the fan module 2 rotates 180°, the mounting plate 21 may be installed again in coordination with the rectangular structure of the window 13, at which point the position of the fan body 23 may be displaced relative to the original position.

[0040] Of course, the window 13 can also be other regular n-gon windows or circular windows, and the mounting plate 21 is adapted thereto. When the window 13 is other regular n-gons, the preset angle of rotation of the fan module 2 is 360° / n, that is, after the fan module 2 rotates 360° / n, it can be installed again in coordination with the window 13, and the position of the fan body 23 will be misaligned compared to the original position. For example, when the window 13 is a regular pentagon, the fan module 2 can be installed again in coordination with the window 13 after rotating 360° / 5=72°. Other regular n-gons will not be described in detail one by one, and the above embodiments can be referred to for details.

[0041] If the window 13 is a circular window, the preset rotation angle of the fan module 2 can be any angle. After rotating to any angle, the mounting plate 21 can still be installed in conjunction with the window 13 again, and the position of the fan body 23 is misaligned.

[0042] In addition, the shape of the window 13 can also be irregular, and similarly, the mounting plate 21 is adapted thereto. There are no excessive restrictions on the preset angle, but it is necessary to ensure that after the fan module 2 rotates the preset angle (except 360°), the mounting plate 21 can be installed in conjunction with the window 13 again.

[0043] The above provides a technical solution for realizing the offset adjustment of the fan body 23 in a window 13. If there are multiple windows 13, each corresponding fan module 2 in the multiple windows 13 can also be rotated to adjust the position of the fan body 23; similarly, by adjusting a single fan module 2, the fan bodies 23 in multiple windows 13 can also be relatively offset, so that the layout of the entire fan unit is more reasonable and the working efficiency is higher.

[0044] Based on the above embodiments, the present application takes the window 13 as a square window as an example for introduction. There are many ways to form the square window 13, for example, a plurality of windows 13 distributed in columns and rows are formed by staggering the cross beams 11 and the longitudinal beams 12. Figure 2 Specifically, the installation frame 1 includes a plurality of cross beams 11 and a plurality of longitudinal beams 12 perpendicular to the cross beams 11. The cross beams 11 and the longitudinal beams 12 are staggered to enclose a plurality of windows 13 in columns and / or rows. Of course, it can be a single column or a single row, or multiple columns and rows.

[0045] In this case, in order to allow the fan modules 2 of the same specification to be installed in conjunction with each window 13, each window 13 is also set to the same specification, that is, the length, width and height of each window 13 are respectively the same, and the installation method is simple and quick.

[0046] In addition, considering that when the fan modules 2 are arranged in a larger cabinet space, it is necessary to reasonably allocate the layout position of each fan module 2 so that the air in the cabinet can achieve sufficient heat exchange. Here, in the fan modules 2 in two adjacent windows 13 in the same column or row, one fan module 2 can be rotated at a preset angle and installed with the corresponding window 13, and the other one can remain in its original state, so that the fan bodies 23 in adjacent fan modules 2 are staggered to increase the working width of multiple fan bodies 23 when working, thereby improving the heat exchange efficiency of the air in the cabinet.

[0047] Of course, in the windows 13 of adjacent columns or rows, the fan modules 2 in one column or row of windows 13 can be rotated at a preset angle and installed with the corresponding window 13, while the other column or row remains in its original state, so that the fan bodies 23 in the fan modules 2 of the adjacent columns are dislocated in the lateral direction. Figure 3 , or the fan bodies 23 in adjacent rows of fan modules 2 may be misaligned in the longitudinal direction.

[0048] When the window 13 is enclosed, the two horizontal beams 11 serve as a set of opposite sides in the frame, and the two longitudinal beams 12 serve as another set of opposite sides in the frame; of course, the horizontal beams 11 and the longitudinal beams 12 may include a beam body and a connector fixedly arranged on the inner wall of the beam body, and the connector may also serve as a frame constituting the window 13. In other words, when the window 13 is enclosed, it is not limited to only use the beam body as the frame of the window 13, and other connectors fixedly connected to the beam body may also be used, but it is necessary to ensure that the connection between the connector and the mounting plate 21 and the connector and the beam body is stable and sealed.

[0049] In some embodiments, the mounting plate 21 can be arranged horizontally, and the window 13 is a horizontal window adapted thereto, and the axis of the fan module 2 generally extends up and down; in this case, the fan module 2 does not require high horizontal limit during installation, and mainly requires limit in the up and down directions to ensure support for the fan module 2. Therefore, support strips extending toward the inner side of the window 13 are arranged in at least one set of opposite sides of the frame to support the edge of the mounting plate 21; when the fan module 2 has not yet completed fixed connection with the frame of the window 13, the fan module 2 can be placed in the window 13 from top to bottom, and the fan module 2 is supported by the support strips of the frame to facilitate further connection between the fan module 2 and the frame.

[0050] In addition, for large cabinets, personnel may need to walk inside the cabinet to complete equipment inspection, maintenance and other operations. Therefore, the mounting plate 21 is embedded in the window 13, and the support bar is located at the lower edge of the frame, that is, the lower surface edge of the mounting plate 21 is against the support bar, and the upper surface of the mounting plate 21 is flush with the upper surface of the frame, so that the fan module 2 and the mounting frame 1 form a flat surface for personnel to walk smoothly. Of course, for the opening 22 corresponding to the fan body 23, protective devices such as protective nets can be set to protect personnel without affecting air circulation.

[0051] On the basis that the fan module 2 is supported by the support bar, the fan module 2 can be fixed to prevent unstable conditions such as shaking during operation. The side wall of the mounting plate 21 is abutted against the frame to ensure a certain sealing and fitting effect, and is fixedly connected to the frame by fasteners. The fasteners can be one or more of screws, bolts, clamping devices, plug-in devices, and other connecting devices. The details will not be repeated here, and the details can be referred to the prior art.

[0052] In addition, in order to facilitate personnel to install the fan module 2 on the installation frame 1, the fan module 2 here also includes a handle provided on the installation plate 21, and personnel can lift the fan module 2 by the handle and put it into the corresponding window 13 from top to bottom. Preferably, the handle is located on the upper surface of the installation plate 21, does not affect the matching of the installation plate 21 and the window 13, and the handle is detachably connected to the installation plate 21. After the fan module 2 is installed, the handle can be removed, so that the installation frame 1 and the fan module form a flat walking surface.

[0053] The present application also provides a cooling unit comprising any one of the above-mentioned fan units, and the cooling unit also has high working efficiency.

[0054] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0055] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
