Extraction fan unit

technical field

The utility model relates to an extractable fan device, in particular to a fan that can be quickly assembled with a fan module and simultaneously connected to a power supply to start operation, which is convenient for the fan to be assembled or disassembled without using tools and without plugging in a power cord. It can effectively prevent the internal space from messing up and affecting heat dissipation.

Background technique

With the vigorous development of high technology, the volume of electronic components tends to be miniaturized, and the density per unit area is getting higher and higher, and their performance is continuously enhanced. Under these factors, the heat generation of electronic components is almost year by year. If there is no good heat dissipation method to eliminate the heat energy generated by electronic components, these excessive temperatures will cause electronic components to generate electron ionization and thermal stress, which will reduce the overall stability and shorten the electronic components themselves. Life expectancy has always been a problem that cannot be ignored.

As personal computers have become popular in today's society, and the life cycle of the computer generation is shorter, the elimination rate of its electronic components (such as: central processing unit (CPU) and image processing unit (GPU), etc.) is also increasing, and the central As the performance of the processor increases and the processing speed increases, the heat emitted is also increasing. However, the surface area of the central processing unit has not changed much. The current operating temperature of the central processing unit is about 60°C. ~95°C, if this situation continues to develop, the wattage of heat will continue to increase. If there is no perfect heat dissipation device, it will seriously affect the normal operation of the CPU and image processor, so how to improve the cooling performance of the radiator? Heat dissipation performance is a very important task; however, at present, most of the fan directly blows cold air to the electronic components to achieve the cooling effect. Components, if combined with optimized design, will be more beneficial to solve the problem of heat dissipation of electronic components; then in order to solve the problem of heat dissipation performance of the above-mentioned existing electronic components, the applicant once used the "cooling device of server mainframe" on May 31, 2002 "New patent case, please refer to Fig. 8, utilize server main frame A to be provided with horizontal bar A1 inside, and be provided with a plurality of centrifugal turbofans B on the horizontal bar A1, and turbofan B is to have contracted air outlet B1 , that is, through the air outlet B1, the cold air is blown to the object to be cooled inside the server machine A, which can prevent the blown cold air from overflowing to the surroundings, so as to improve the heat dissipation effect of the turbofan B; but the turbofan B is fixed on the crossbar A1 , it will be hindered by the components around the cross bar A1, which will affect the inconvenience when installing or disassembling the turbofan B, and it is also quite troublesome when cleaning or maintaining. In addition, the turbofan B is fixed at a predetermined position on the cross bar A1 , but server mainframe A produced by different manufacturers and production industries, its internal central processing unit, chip, adapter card, hard disk and other heat-prone electronic components are equipped with different positions and specifications, so turbofan B will not be able to Blowing cold air directly to the heating electronic components will instead blow the heat energy of the heating components to other electronic components, causing more heat energy to be accumulated inside the server host A and the temperature will continue to rise, which will lead to a decrease in the performance of the electronic components.

In order to improve the problems of the above-mentioned previously proposed patent case, the applicant filed a new patent application for "extractable fan module" on October 12, 2004. The case was announced in the patent gazette on May 11, 2005. The certificate number is M264830, please refer to Fig. 9 and Fig. 10. It is inside the hollow seat C to form a storage chamber C1 that can accommodate the fan B, and at least one fan B is combined in the storage chamber C1. The positioning frame C2 is provided with a corresponding guide groove C11 and a guide part C21 on the accommodation chamber C1 and the positioning frame C2, so that the fan B can be combined with the positioning frame C2, and the fan B can be quickly replaced. , and does not require the use of tools for disassembly and assembly purposes, but there are still some deficiencies in use, such as:

(1) The hollow seat C is relatively large in volume and tends to take up a lot of space, which does not meet the requirements of light, thin, short and small modern electronic products.

(2) The fan B must be connected to the internal power cord of the server host A to make the fan B run. Therefore, the more fans B are installed on the crossbar A1, the more power cords are connected, which will easily cause the internal power cord of the server host A to be damaged. Messy and affect the circulation of fan B airflow.

(3) The fan B is inserted into the accommodation chamber C1 of the seat body C by using the positioning frame C2, but it has not achieved the fixed function. During the transportation and movement of the seat body C, the fan B may easily cause the fan B to shake, shift, and collide in the seat body C. unstable situation.

Therefore, how to solve the problems of assembly and disassembly of existing fans and scattered power lines is the direction that relevant manufacturers engaged in this industry eagerly want to study and improve.
