Symmetrical series fan structure

Abstract

A symmetrical series fan structure includes multiple frame bodies made with single mold. Each frame body has a first through hole, a second through hole and a base having multiple connection members. The base is positioned in the second through hole on one side of the frame body and connected to the frame body via the connection members. The frame body has multiple fixing members and multiple fixing holes on the same side of the frame body as the base. The frame bodies are serially connected by means of inserting the fixing members into the fixing holes with the bases and the connection members of the frame bodies attached to each other. Accordingly, the frame bodies can be made with single mold and assembled to form the symmetrical series fan structure. In this case, the mold development cost is saved and the manufacturing cost is lowered.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a series fan structure, and more particularly to a series fan structure in a symmetrical form. The frame bodies of the series fan structure can be made with single mold and assembled to form the symmetrical series fan structure. In this case, the mold development cost is saved and the manufacturing cost is lowered.[0003]2. Description of the Related Art[0004]Recently, the internal circuits of the integrated circuit (IC) chip have been laid out more and more compactly. Consequently, the chip generates higher and higher heat. When a personal computer works, the compact IC chip such as CPU or graphics chip will generate high heat. In order to keep the IC chip functioning lastingly, it is necessary to maintain the IC chip at an optimal working temperature. In this case, rise of temperature can be avoided so as not to deteriorate the efficiency of the IC chip or damage the IC chip. ...

AI Technical Summary

Benefits of technology

[0011]A primary object of the present invention is to provide a symmetrical series fan structure. The frame bodies of the symmetrical series fan structure can be made with single mold and assembled to form the symmetrical series fan structure. Accordingly, the mold development cost is saved to lower the manufacturing cost.

[0012]To achieve the above and other objects, the symmetrical series fan structure of the present invention includes multiple frame bodies. Each frame body has a first through hole, a second through hole and a base. The first and second through holes are respectively formed on two sides of the frame body. Multiple connection members extend from a circumference of the base. The base is positioned in the second through hole and connected to the frame body via the connection members. In addition, the frame body has multiple fixing members and multiple fixing holes on the same side of the frame body as the base. The frame bodies are serially connected by means of inserting the fixing members into the fixing holes with the base and the connection members of one frame body attached to the base and the connection members of another frame body. Accordingly, the frame bodies can be made with single mold and serially assembled to form the symmetrical series fan structure. In this case, the mold development cost is saved and the manufacturing cost is lowered. Accordingly, the present invention has the following advantages:

[0013]1. The mold development cost is saved.

[0014]2. The manufacturing cost is lowered.

Problems solved by technology

When a personal computer works, the compact IC chip such as CPU or graphics chip will generate high heat.

This leads to increase of mold development cost and manufacturing cost.

1. The mold development cost is increased.

2. The manufacturing cost is increased.
