Benefits of technology

"The present invention provides a composite type transverse air flow fan that can adjust the number of fan blades to meet heat dissipation needs. It is easy to assemble and has a larger area for heat dissipation."

Problems solved by technology

Although the preceding improvements can reach purpose of promoting circulation of air flow, effects such as simple assembling, expanding heat dissipation area and adjustable number of fan blades for meeting heat dissipation need are not possible to be obtained at the same time.

first embodiment

[0017] Referring to FIGS. 1 and 2, a composite type transverse flow fan according to the present invention basically includes a drive device 11, which can be a motor, and a fan blade module 12, which is attached to the drive device 11. The fan blade module 12 further includes at least one fan blade part 121, at least one fan frame 122 and at least one rotating shaft 123. The fan frame 122 has a first joining part 122a and a second joining part 122b detachably engaging with each other. The rotating shaft 123 has a first coupling part 123a and a second coupling part 123b detachably engaging with each other. The fan blade part 121 has a projection 121a with a pivot hole 121b at the center thereof. The pivot hole 121b fits with the rotating shaft 123 with a bearing 123c and a bearing 123d provided between the pivot hole 121 and the rotating shaft 123. The bearings 123c and 123d allow the rotating shaft 123 rotationally contacting with the fan frame 122 such that the fan blade part 121 r...

second embodiment

[0021] Referring to FIGS. 3 and 4, a composite type transverse fan according to the present invention is illustrated. The fan frame 222 has a first joining part 222a and a second joining part 222b detachably engaging with each other. The rotating shaft 223 has a first coupling part 223a and a second coupling part 223b detachably engaging with each other. The fan blade part 221 has a projection 221a with a pivot hole 221b at the center thereof. The pivot hole 221b fits with the rotating shaft 223 with a bearing 223c and a bearing 223d provided between the fan frame 222 and the rotating shaft 223. The bearings 223c and 223d allow the rotating shaft 223 rotationally contacting with the fan frame 222.

[0022] For assembling, the second coupling part 123b has a receiving hole 123n and the first coupling part 223a has a fitting hole 223e with a chamber 223f. The chamber 223f has an open side 223g with a stopper 223h and a lateral side of the chamber 223f opposite to the open side 223g has a...

Abstract

A composite type transverse flow fan has a driving device and a fan blade module, which is attached to the driving device. The fan blade module further includes at least a rotating shaft, at least a fan blade part and at least a fan frame. The fan blade module further includes at least a rotating shaft, at least a fan blade part and at least a fan frame. The rotating shaft has a first coupling part and a second coupling part and both of the coupling parts detachably engage with each other. The fan blade part is attached to the rotating shaft. The fan frame is attached with the rotating shaft and provides a first joining part and a second joining part and both the joining parts detachably engage with each other. Once the driving device is in operation, the fan blade part is capable of rotates in the fan frame.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of Invention [0002] The present invention is related to a composite type transverse flow fan and particularly to a fan structure with composite fan blades. [0003] 2. Brief Description of Related Art [0004] A major function of the current fan is to induce circulating air flow to articles needed to be cooled. Thus, if the circulating air flow is able to be increased, effect of heat dissipation for the cooled articles can be enhanced. [0005] However, in order to promote the circulating air flow, improvements of the conventional fan device have been performed and are classified into two options: (1) improvement of driving device and (2) improvement of fan blades. The improvement of driving device further is divided into two ways (a) improvement of rotational speed and (b) improvement of stabilizing rotation. The improvement of fan blades further is divided into two ways (a) improvement of each fan blade and (b) increase of number of the fan bl...
