[0044] It should be pointed out here that although the mounting structure of the centrifugal fan of the utility model is an H-shape having a transverse portion and a longitudinal portion, the number of the transverse portion and the longitudinal portion is not limited to one and two respectively, but can be increased according to the specific application scenario; in addition, the angle between the transverse portion and the longitudinal portion is not necessarily exactly 90°, but can be set to other angles according to the specific application scenario, for example, the two are inclined to each other at angles other than 90°.

[0045] The present invention will be further described below in conjunction with specific embodiments with reference to the accompanying drawings.

[0046] Figure 1 and Figure 2 The front view and the structural diagram of the installation structure of a centrifugal fan of an embodiment of the utility model are respectively shown. It should be noted that, in order to facilitate the display of its internal structure, Figure 2One side panel, power line and control line are omitted. As shown in the figure, a centrifugal fan installation structure includes an H-shaped fan bracket 101, and the fan bracket includes a transverse portion and longitudinal portions on both sides, wherein a through hole is provided at the center of the transverse portion, and the motor part of the centrifugal fan 001 is fixed at the through hole. In order to minimize the obstruction of the air supply surface as much as possible, in one embodiment of the utility model, the overall width of the fan bracket and the height of the transverse portion are not greater than the diameter of the air inlet part of the centrifugal fan. Preferably, the height and width of the transverse portion are substantially equal to the diameter of the motor part of the centrifugal fan.

[0047] In order to facilitate wiring, in one embodiment of the utility model, the longitudinal portion of the fan bracket is provided with a wire groove, and the power line 011 and the control line 012 of the centrifugal fan 001 are respectively arranged along the wire grooves of the longitudinal portion on both sides of the fan bracket.

The L-shaped structure is adopted, that is, the cross section of the four legs of the fan bracket is L-shaped, which meets the structural strength while minimizing the obstruction to the positive air supply surface, further improving the air supply efficiency of the centrifugal fan.

[0048] In another embodiment of the utility model, a wire binding hole is further opened in the longitudinal portion of the fan bracket, and a cable tie is used to tie the wiring harness of the power line 011 and the control line 012 through the wire binding hole, so that the power line 011 and the control line 012 are placed on both sides without interfering with each other, and at the same time, the overall installation structure can be made more beautiful and neat.

[0049] In one embodiment of the present invention, the fan support 101 is formed by bending a thin steel plate such as a galvanized plate or a cold-rolled plate in one piece, and its thickness is, for example, not greater than 4 mm. In one embodiment of the present invention, the thickness of the thin steel plate is 3 mm.

[0050] As shown in the figure, in one embodiment of the utility model, a plurality of centrifugal fans can be installed in the mounting structure. To achieve this purpose, as shown in the figure, a plurality of sub-cavities are provided in the mounting structure, wherein at least one centrifugal fan is installed in each sub-cavity through the fan bracket as described above.

[0051] Based on this, in one embodiment of the utility model, the mounting structure further includes a shell and a partition 103.
