Embodiment Construction

[0056] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments of the present invention will be described in detail below together with the accompanying drawings.

[0057] Please refer to Figure 5 and Figure 6As shown, the fan frame of the present invention at least includes a metal fixing frame 1 and a plastic frame body 2 . The plastic frame 2 can be combined with the metal fixing frame 1; the metal fixing frame 1 can be combined with components (not shown) such as a stator and a fan wheel, so as to form a cooling fan. This embodiment discloses that the fan frame is a fan frame of a blower fan, and the cooling fan can also be a fan frame of an axial fan or a fan frame of a horizontal convection fan, which is not limited in the present invention.

[0058] The above-mentioned metal fixing frame 1 has a first surface 11 and a second surface 12 opposite to each other. The first surface 11 is pr...

Abstract

A fan frame and the metal fixing base thereof are used for solving the problem about the radial width and the axis height reduced difficultly of the former fan frame. The fan frame has a metal fixing base and a plastic body. A plurality of fixing rib disposes on the outside edge of the metal fixing base. The plurality of fixing rib is protruding and each has a first combining face and a second combining face correspondingly. The second combining face forms a concave part. The plastic body is integrating and covers to the outer circumference of the metal fixing base. The plastic body combines with the first combining face of the fixing rib of the metal fixing base. The concave part combines with the second combining face of the fixing rib of the metal fixing base.

Description

technical field [0001] The invention relates to a fan frame, in particular to a fan frame comprising a plastic frame and a metal fixing frame that can be combined with each other. Background technique [0002] Please refer to figure 1 and figure 2 As shown, a conventional fan frame 8 is disclosed, and the fan frame 8 includes a metal fixing frame 81 and a plastic frame 82 . The metal fixing frame 81 has a first surface 811 and a second surface 812 opposite to each other. The first surface 811 is provided with a shaft connection portion 813 and a plurality of joint portions 814. The shaft connection portion 813 is located on the metal fixing frame 81. In the middle, relative to the shaft connection portion 813, the plurality of joint portions 814 are adjacent to the outer periphery of the metal fixing frame 81, and the plurality of joint portions 814 are a plurality of convex ribs formed on the first surface 811; therefore The plastic frame 82 can be integrally coated on ...
