Description

Technical Field

[0001] The utility model relates to the field of fans, in particular to a centrifugal fan installation panel and a centrifugal fan. Background Art

[0002] In centrifugal fans, an outer rotor motor is often used to connect the fan and the turbine. During the connection process between the fan and the mounting panel, the mounting panel is a flat structure. The distance between the center of mass of the fan and the mounting panel is too large. When the fan is started, the entire centrifugal fan will shake, affecting the stability of the fan.

[0003] In summary, how to reduce the shaking of the fan during operation has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to reduce the shaking of the fan when it is working;

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The utility model is a centrifugal fan installation panel, comprising: a plate body, the side of which has an upward flange, and a hole body for the fan housing to pass through; the hole body is horizontally punched upward to form a mounting ring and a connecting portion connecting the plate body and the mounting ring; when the fan is connected to the mounting ring, the center of mass of the fan is raised and the center of mass is closer to the plate body;

[0007] Compared with the installation panel with a flat structure, the hole of the installation panel in this solution is stamped upward to achieve bending. Since the bending of the installation panel enhances the strength of the installation panel, the installation panel is less likely to shake when the fan is working. In addition, the installation ring is set above the installation panel by stamping. In this way, when the fan is installed, the center of mass of the fan is increased, making the center of mass of the fan closer to the installation panel. In this way, the shaking can be reduced when the fan is working.

[0008] The use of stamping enhances the strength of the mounting panel and can reduce the thickness of the mounting panel material. For example, by changing the original 6mm thick material to a 4mm thick material, the fan can be fixed, reducing costs.

[0009] To specifically illustrate how the fan is connected, the utility model includes a centrifugal fan mounting panel and an air guide plate; connecting brackets are provided on both sides of the air guide plate; the connecting brackets are fixedly connected to the flange of the plate body; the fan is connected to the mounting panel;

[0010] In the centrifugal fan of this solution, the fan is arranged vertically, the mounting panel is used to fix the fan, a turbine is arranged between the fan and the air guide plate, and the mounting panel and the separation are connected by a connecting bracket to support the mounting panel and the fan.

[0011] In order to illustrate how the mounting panel is connected to the connecting bracket, the present invention adopts the method of fixing the flange and the connecting bracket by welding;

[0012] The flange of the mounting panel and the connecting bracket are fixedly connected by welding.

[0013] In order to illustrate how the mounting ring is connected to the fan, the utility model adopts a mounting hole on the mounting ring; a connecting flange, which is connected to the fan; a fastener passes through the mounting hole and the connecting flange to fix the fan and the mounting ring;

[0014] When the fan passes through the mounting ring, the mounting ring contacts the connecting flange, and the mounting ring and the connecting flange are connected by fasteners, thereby achieving connection between the mounting ring and the fan.

[0015] Beneficial effects of the present invention: The present invention is a centrifugal fan mounting panel. The hole of the mounting panel in this solution is stamped upward to achieve bending. The bending of the mounting panel enhances the strength of the mounting panel, so that the mounting panel is not prone to shaking when the fan is working. In addition, the mounting ring is set above the mounting panel by stamping. In this way, when the fan is installed, the center of mass of the fan is improved, so that the center of mass of the fan is closer to the mounting panel. In this way, the shaking can be reduced when the fan is working. BRIEF DESCRIPTION OF THE DRAWINGS
