Abstract
The utility model provides a computer power source, which is characterized in that a fan with the diameter larger than 80 mm is arranged on the top part of the outer shell of the computer power source, and a wind outlet is arranged on one side wall of the outer shell of the computer power source. The computer power source of the utility model not only improves power source ventilation amount but also reduces noise of the power source and the entire machine compared with existing computer power source.
Description
Technical field
The utility model belongs to field of computer technology, relates to a kind of computer power supply particularly.
Background technology
Existing computer power supply is the side on its shell but not the top is provided with a fan, because the restriction of outer casing of power supply side wall dimensions, the diameter of fan only is 80mm, opposite side at the outer casing of power supply sidewall is provided with air inlet, this fan be installed in computer cabinet inside air outlet near, thereby the air-flow that produces by fan rotation comprises that with computer cabinet inside the heat that power supply produces discharged by fan through air outlet.In design in the past, if allow ventilation reach 15cfm, noise is less than 38db, and the minimum needs of the rotating speed of this fan reach about 2500rpm so.In addition, also be provided with a temperature control circuit in computer power supply, purpose is that power supply is not under the awfully hot situation, reduces rotation speed of the fan, to reduce noise.
Along with the development of computing machine, people have had higher requirement for the noise of complete machine.The generation of noise and the fan of power supply have direct relation.Because the parts thermal value of computer-internal constantly raises, in order to solve heat dissipation problem, traditional mode is to realize that by the rotating speed that improves power supply fan the complete machine noise will improve like this, and obvious this method can not satisfy user's demand.
Summary of the invention
The purpose of this utility model is to provide a kind of computer power supply, and than existing computer power supply, it has not only improved the power supply ventilation, has reduced power supply and complete machine noise.
In order to realize above-mentioned purpose of the present utility model, a kind of computer power supply is provided, it is characterized in that a diameter is set at the top of computer power supply shell greater than the fan of 80mm; One air outlet is set on the sidewall of computer power supply shell.
In one embodiment, this computer power supply is installed in the inside of computer cabinet, makes its air outlet be positioned near the chassis intake, and its top fan is away from chassis intake and be positioned at the top of the CPU of cabinet.
In one embodiment, the diameter of described fan is 120mm.
In one embodiment, described fan is set at the inboard of computer power supply shell.
In one embodiment, described air outlet is made up of the little air vent of a plurality of spaces, and spreads all over the whole sidewall of the computer power supply shell at its place.
In one embodiment, the temperature control circuit in described computer power supply can be removed.
According to computer power supply of the present utility model, it has following advantage:
(1) by fan being arranged on the top of computer power supply shell, make and to adopt the fan of diameter greater than 80mm, thereby improved ventilation, reduced rotation speed of the fan, reduced the power supply fan noise, and the rotating speed of cpu fan is reduced, reduced the noise of cpu fan, thereby reduced the noise of complete machine;
(2) fan is arranged on the inside of outer casing of power supply, has further reduced the noise of power supply fan;
(3) raising of ventilation makes and can select to be provided with or not to be provided with the temperature control circuit part in the computer power supply, if the cancellation temperature control circuit then can make the life-span of power supply fan be extended, has reduced the cost of power supply.

Fig. 2 is the side view of the computer power supply shown in Fig. 1;
Fig. 3 is the structural representation that the cabinet of the computer power supply shown in Fig. 1 is housed; And
Fig. 4 is equipped with the rear portion general perspective of the cabinet of the computer power supply shown in Fig. 1
Embodiment
Following with reference to accompanying drawing, to being elaborated according to an embodiment of the present utility model.
Referring to accompanying drawing 1-3, show a kind of computer power supply 1 according to an embodiment of the present utility model, wherein a diameter is the top that the fan 2 of 120mm is set at computer power supply shell 3, and an air outlet 4 is set on the sidewall of computer power supply shell 3.Described fan 2 is set at the inboard of computer power supply shell 3.Described air outlet 4 is made up of the little air vent of a plurality of spaces, and spreads all over the whole sidewall of the computer power supply shell 3 at its place.When this computer power supply 1 is installed in the inside of computer mainframe box 5, its air outlet 4 be positioned at ventilating opening 6 on the rear wall of cabinet 5 near, and the fan that its top is provided with is away from chassis intake 6 and be positioned at the top of CPU, make by the blowing of fan 2, cabinet inside is comprised that the heat that power supply and CPU produce blows out outside the cabinet 5 by ventilating opening 6.
Through test, by using the fan 1 of 120mm, satisfying under the condition that ventilation reaches 20cfm, the rotating speed of fan 1 is on 1200 right sides of turning left, and noise is reduced to below the 30db.Fan 1 is arranged on the inside of outer casing of power supply 3, has further reduced the noise of power supply fan 1.In order to increase radiating effect, carry out exhausting by fan 1, increased the size of air outlet simultaneously, the components and parts height on the circuit board in the outer casing of power supply 3 is accomplished minimum, can make the ventilation of power supply increase 5cfm, noise reduces 10db.The raising of ventilation makes can be provided with or not be provided with the temperature control circuit part in the computer power supply, if remove temperature control circuit, has then prolonged the life-span of power supply fan 1, has reduced the cost of power supply.
Be to be understood that, though the utility model is described in the mode of specific embodiment, but be not limited to described specific embodiment, also comprise the possible modification and the change that are not separated with principle of the present utility model and spirit, for example the diameter of fan 1 can be 100mm or 110mm.
