ABSTRACT:
FIELD OF THE INVENTION
The present invention is related to an extracted and positioning device of a fan, and especially to a structure by which the fan can be extracted from or positioned in a computer.
BACKGROUND OF THE INVENTION
As shown in
FIG. 5
, a prior art fan is shown. The fan
1
is directly positioned and fixed to a casing
2
of a computer. In a more original way, the fan
1
is installed at a position of a power source. The fan
1
is primarily used to dissipate heat of a computer. Even the central processing unit has a dedicated fan. The function of the fan serves to transfer the heat generated in the computer case to outer environment for reducing temperature in the computer case so that the mother board and interface board in the computer casing has a preferred operational environment. Even in an air conditioned room, the computer remains to dissipate heat, otherwise the heat will accumulated in the computer casing so that the temperature within the casing will increase. This is disadvantageous for the operation of a computer. The chips in an electronic device is more necessary to dissipate heat. If the temperature is too high, the operations and signal transformation will be unsteady, some problems will occur. This is possible to affect the operation speed of the computer. Even the computer possibly shuts down. This has a bad effect to the use of information. Therefore, it is a basic demand for a computer to dissipate heat normally and uninterrupted so that the components can be used efficiently. This is especially important for industrial computers.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide an extracted and positioning device of a fan. Thereby, a fan in a prior art which is fixed to a single position can be used in a long period operational industrial computer. In order to meet the requirement of sufficient heat dissipation, no tripping, no shutting down, in general, a plurality of fans are installed in an industrial computer for dissipating heat. In order for the computer to be used successfully, it can not be shut down in operation. In a general computer, it is impossible to update components without shutting down. Currently, only part of extractable hard disk is possible. Thus, there is a further demand for a novel design in which the fans of a computer can be updated or added without shutting down. This is the primary object of the present invention.
Therefore, the present invention provides an extracted and positioning device of a fan suitable to be used in industrial computers. A frame of a computer casing is installed with at least one fan fixing frame; the fixing frame is a frame body; each of two sides of the frame body is disposed with a lateral plate; the inner surface of each lateral plate has inward flanges; a rear end of the of the lateral plate is connected to a rear plate; a front bottom plate is connected in front of the lateral plate; a buckle with an elastic press is transversely and forwards protruded from the front bottom plate; further, a slidable frame plate is formed and is engagable with the fixing frame; the slidable frame plate has a
(a Chinese word) shape; the slidable frame plate is slidable with two protrusion of the frame body; a front end of the frame plate has a pull with a through hole; a concave portion is at a middle portion of the front end of the pull, thereby, as the frame plate slides into the frame body, it can be positioned by the buckle; each of the four corners of the frame plate is connected to a fan; the fan slides on the fixing frame with the frame plate.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
