Description
The present invention relates to a kind of means for fixing electric fan for computer, particularly relate to and a kind ofly can adjust fan and make computer system obtain the best heat radiation and the locating device of ventilation effect according to the position of central processing unit on the computer substrate.
Heat radiation and to ventilate be one of sixty-four dollar question in the computer system particularly for the heat-generating electronic elements on the computer substrate, as the heat that central processing unit produced, if can not be in time, suitably got rid of, certainly will influence the computer allomeric function.For the heat dissipation problem of computer inside, its solution all adopts increased the computer casing inner air convection to reach the heat radiation order in the past, and it roughly can divide into following two big classes:
1. passive type heat loss through convection, general installing heat radiator (Heat Sink) is in central processing unit, the fan of power supply unit drives flowing of the interior air of computer casing in the mat computer system, and the air vent of appropriate location on the matching computer housing, cause the convection current of housing inner air and outer air, take away the heat that central processing unit produces.
2. active heat loss through convection is directly set up a fan on the central processing unit of installing heat radiator, force cross-ventilation concentrate on central processing unit directly over, the heat of discharging central processing unit by this and being produced.
For the one-piece computer system, the radiating effect of passive type convection current is obviously good not as active heat loss through convection.Yet active heat loss through convection only concentrates on central processing unit with cross-ventilation, for the radiating effect of other thermal source of computer inside and may not be certain more effective than passive type heat loss through convection.Simultaneously, active heat loss through convection must install the less fan of a size additional, the work efficiency of this fan usually is subjected to the temperature effect of central processing unit, and the situation that has instability even fan life is shortened takes place, and then influences the operating characteristic of central processing unit.Moreover the degree of difficulty of more little its manufacturing of size of fan and precision requirement are just high more, must reduce temperature simultaneously again to the influence that it produced, and therefore, obviously can exceed many than passive type heat loss through convection device on cost.
No matter be passive type heat loss through convection or active heat loss through convection, behind device such as plant expansion board and other winding displacement in the computer casing, the computer casing inner air flow is very not smooth, and then influences its radiating effect.If install fan additional, increase the housing inner air convection, no matter central processing unit with active heat loss through convection or passive type heat loss through convection, all will increase the radiating efficiency of computer system at the computer casing ad-hoc location.Yet on the different computer substrate, the position that its central processing unit disposed is also incomplete same under the same size, and the radiating airflow after the enhancing can't be determined the central processing unit position by each different computers substrate configuration, to reach best radiating effect.Therefore, the problem of central processing unit heat radiation still can't obtain best solution.
From the above, no matter be active, passive type heat loss through convection in the prior art or on computer casing, install fan additional, all there is certain problem and is badly in need of improving for the heat radiation in the computer casing.More than Xiang Guan prior art can be with reference to United States Patent (USP) the 4th, 712, and 159,4,890,196,5,208,731,5,276,585,5,486,980 and 5,502, No. 619 etc.
The object of the present invention is to provide a kind of means for fixing electric fan for computer, fan can be fixed on and make air produce the position of suitable convection current, make the heat-generating electronic elements of computer substrate,, can obtain best radiating effect as central processing unit etc.
Another object of the present invention is to provide a kind of means for fixing electric fan for computer, it can import the computer casing air outside, makes this air directly deliver to the electronic component top, to reach better radiating effect.
The object of the present invention is achieved like this, a kind of means for fixing electric fan for computer promptly is provided, is installed in computer casing, the computer fan on it is in order to the electronic component on the cooling computer substrate, described means for fixing electric fan for computer comprises: fan base is in order to install this computer fan; Support, be provided with fixed mount, it is installed in described computer casing, and fan Fixture, it is the hollow framework, and this fan base is installed on this hollow framework slidably, and is fixedlyed connected by a fixture with this hollow framework, described fixed mount is provided with fixed orifice and reaches fixedly ora terminalis, is fastened in relative grab set on the described computer casing wall; By this, described computer fan can carry out forced convertion to the air in the computer casing, to reach radiating effect.
The present invention also provides a kind of means for fixing electric fan for computer, is installed in computer casing, the electronic component of described computer fan in order to generate heat on the cooling computer substrate, and described means for fixing electric fan for computer comprises: fan base is in order to install this computer fan; Support, be provided with first, be installed in described computer casing, and second portion, it is the hollow framework, and this fan base is installed on this hollow framework slidably, and is fixedlyed connected by fixture with this hollow framework, described first is provided with fixed orifice and reaches fixedly ora terminalis, is fastened in relative grab set on the described computer casing wall; Described computer casing is provided with at least one through hole at the described means for fixing electric fan for computer of installing position periphery, and described computer fan can carry out forced convertion to the air in the computer casing, to reach the effect of heat radiation.
Principal feature of the present invention is, fan is installed on the computer casing, air that can computer casing is outer imports and reinforcement computer casing inner air convection, but and the position of central processing unit on the matching computer substrate, change the position of fan, make the convection current of air concentrate on central processing unit, and then cause central processing unit to obtain best radiating effect.It mainly includes: fan base is used to install computer fan; Support comprises fixed mount (first) and fan Fixture (second portion), and wherein, this fixed mount is fixedly arranged on computer casing, and this fan Fixture is used to install fan base, and can adjust the position of this fan base according to the difference of computer substrate configuration.
The advantage of apparatus of the present invention is, but the installation site of fan is adjusted in the configuration of its matching computer substrate, thereby reaches the best effect of heat radiation, and easy for installation, tears open and drives easily, so that be convenient to the fan dismounting.
