Problems solved by technology

[0002] In the existing heat dissipation fans, for example, the heat dissipation fans of notebook computers are gradually developing in the direction of lightness and thinness, which makes it difficult to meet the requirements of the strength of the heat dissipation fan while reducing the weight of the heat dissipation fan. To support the edge of the cooling fan shell, but the support effect on the cooling fan shell is limited, there is still the situation that the cooling fan shell is deformed when it is under pressure and interferes with the rotation of the fan blades, and it is easy to damage the cooling fan

Embodiment 1

[0023] This embodiment provides an anti-extrusion cooling fan housing, such as Figure 1~2 The application of the anti-extrusion cooling fan housing to the cooling fan of the notebook computer is shown as an example, but not limited to the application to the cooling fan of the notebook computer. In this embodiment, the anti-extrusion cooling fan housing includes a first end plate 1, a second The end plate 2, the support frame 3 and the support column 4, the first end plate 1 and the second end plate 2 are arranged in parallel and respectively clamped with the two ends of the support frame 3, there are several support columns 4, and each support column 4 is connected to the second end plate. One end plate 1 or the second end plate 2 is vertically arranged, and the support column 4 can directly or indirectly transmit the pressure to the supporting structure outside the heat dissipation fan shell when the heat dissipation fan shell is under pressure, so that the first end plate 1 ...

Embodiment 2

[0031] This embodiment provides an anti-extrusion cooling fan housing. The difference between this embodiment and Embodiment 1 is that one end of each support column passes through the first end plate and is fixedly connected with the first end plate, and the support column The other end abuts against the inner surface of the second end plate, and the bottom shell of the notebook computer is provided with an auxiliary support structure fixedly connected or integrally formed with the bottom shell of the notebook computer on the outside of the second end plate and at the corresponding positions of the supporting columns , when the keyboard part of the notebook computer is under pressure, when the pressure is transmitted to the heat dissipation fan shell, because each supporting column extends out of the first end plate, it contacts the keyboard part of the notebook computer before the first end plate, and the supporting column is subjected to the pressure of the notebook computer....

Embodiment 3

[0033] This embodiment provides a centrifugal cooling fan, such as figure 2 As shown, including the fan wheel 6 and the anti-extrusion cooling fan housing of either the first or second embodiment, the first end plate 1 is provided with an air inlet 7 , and the support frame 3 is provided with an air outlet 8 .

Abstract

The invention discloses an anti-extrusion heat dissipation fan shell, and relates to the technical field of cooling fans,. The anti-extrusion heat dissipation fan shell comprises a first end plate, asecond end plate, a supporting frame and supporting columns. The first end plate and the second end plate are arranged in parallel and connected with the two ends of the supporting frame in a clampedmode. The number of the supporting columns is multiple, each supporting column is perpendicular to the first end plate or the second end plate, and the supporting columns can directly or indirectly transmit pressure to a supporting structure outside the heat dissipation fan shell when the heat dissipation fan shell is stressed, so that the space between the first end plate and the second end plateis not compressed. In the present invention, when the pressure is transmitted to the heat dissipation fan shell from the shell of equipment provided with the heat dissipation fan shell, such as a notebook computer and the like, the supporting columns bear pressure and directly or indirectly transmit the pressure to a shell of equipment such as a notebook computer, so that spaces in the first endplate and the second end plate of the cooling fan shell are not compressed, and the situation that rotation of a fan wheel of the cooling fan is interfered due to bending deformation of the first endplate or the second end plate is avoided.

Description

technical field [0001] The invention relates to the technical field of heat dissipation fans, in particular to an anti-extrusion heat dissipation fan casing and a centrifugal heat dissipation fan. Background technique [0002] In the existing heat dissipation fans, for example, the heat dissipation fans of notebook computers are gradually developing in the direction of lightness and thinness, which makes it difficult to meet the requirements of the strength of the heat dissipation fan while reducing the weight of the heat dissipation fan. To support the edge of the cooling fan housing, but the supporting effect on the cooling fan housing is limited, and there is still a deformation of the cooling fan housing when it is under pressure and interferes with the rotation of the fan blades, which is very easy to damage the cooling fan. Contents of the invention [0003] The object of the present invention is to provide an anti-extrusion cooling fan housing and a centrifugal cool...
