Abstract
The utility model discloses a heat radiation device for power supplies, comprising a fan and a power supply shell which is provided with a wind inlet and a wind outlet. The heat radiation device for power supplies is characterized in that the fan is arranged at the wind inlet of the power supply shell, and when the fan works, the fan blows wind towards the inner part of the power supply shell. As the utility model installs the fan at the wind inlet, wind volume and wind pressure generated by the fan is sufficient and can reach to everywhere in the power supply shell, so as to achieve an excellent heat radiation effect. The heating temperature of the heating element of the inner part of the power supply shell is evidently lower than traditional heat radiation ways. When the fan operates, noises generated to surrounding environments are relatively small. In order to achieve the same radiation effect, the fan can operates at a relatively slow rotation speed, so as to reduce noises and prolong the service life of the fan.
Description
Technical field
The utility model relates to a kind of heat abstractor of power supply.
Background technology
The heat abstractor of traditional personal computer power supply is that a fan is installed at the air outlet place on power shell, rotation by fan, the hot gas that components and parts heating during the power work is produced is outside air outlet is expelled to power shell, suck cold air by the air inlet on the power shell again, at the inner air-flow that forms of power shell, components and parts to heating cool off, and reach radiating effect.This heat abstractor adopts the mode of the direct exhausting of fan, the air quantity and the blast that produce are extremely limited, can't really reach the purpose of the main heating components and parts of power supply being carried out efficiently radiates heat, and be difficult to make cold air to be flowed through in the power shell everywhere, cause some local hot gas delay in the power shell, cause the damage of components and parts; Because fan is installed on the air outlet place, when power supply was installed on the mainframe box, fan was in the mainframe box outer rim, so produced bigger noise during fan running.In addition, the efficiently radiates heat area of this heat abstractor is confined to the air outlet suitable with fan dimension, and the flow of radiating airflow is restricted, influences radiating rate.
Summary of the invention
The purpose of this utility model provides a kind of good heat dissipation effect and the low power supply heat sinking device of noise.The technical scheme that adopts is as follows:
A kind of heat abstractor of power supply comprises power shell and fan, and power shell is provided with air inlet and air outlet, it is characterized in that: described fan is located at power shell air inlet place and is dried towards power shell inside when work.
In order to ensure the enough big radiating airflow of flow is arranged in the power shell, air outlet should be located on the opposite face of air inlet place face.
In order to strengthen radiating effect, in power shell, be provided with at least one heat radiator.
In order to prevent that dust or other foreign material from entering in the power shell, is provided with guard on air inlet and air outlet.
The utility model is installed in the air inlet place with fan, rotation by fan, suck cold air from air inlet, heating components and parts in cold air and the power shell and the surface of heat radiator contact and generate heat components and parts and heat radiator are cooled off, gas after heat absorption heats up is outside air outlet is expelled to power shell, air quantity and blast abundance that fan produces, and can arrive in the power shell everywhere, reach better heat radiating effect, the heating temp of power shell inner heat components and parts obviously reduces than traditional heat-dissipating mode.Because fan is installed on the air inlet place, when power supply was installed on the computer host box, fan was in mainframe box inside, so the noise that produces during fan running isolated by mainframe box, and is less to the noise effect that surrounding environment produces; Because heat dispersion of the present utility model is relatively good, therefore for to reach same radiating effect, fan can move under lower rotating speed, thereby reduces noise, and prolongs the serviceable life of fan.Since fan is installed in the air inlet place, the efficiently radiates heat area of extendible air outlet, and not only be confined to traditional air outlet suitable with fan dimension, thus increase the flow of power supply internal heat dissipating air-flow, strengthen radiating effect.
Description of drawings
Accompanying drawing is the structural scheme of mechanism of the utility model one preferred embodiment.
Embodiment
The heat abstractor of power supply as shown in drawings, comprise power shell 1 and fan 2, power shell 1 is provided with air inlet 3 and air outlet 4, and air outlet 4 is located on the opposite face of air inlet 3 place faces, and fan 2 is located at power shell 1 air inlet, 3 places and is dried towards power shell 1 inside when work.
In power shell 1, be provided with two heat radiator 5.
Be provided with guard (not drawing in the accompanying drawing) on air inlet 3, air outlet 4 is provided with guard 6.
During the work of this heat abstractor, rotation by fan 2, suck cold air from air inlet 3, heating components and parts in cold air and the power shell 1 and surface of heat radiator 5 contact and generate heat components and parts and heat radiator 5 are cooled off, gas after heat absorption heats up reaches better heat radiating effect outside air outlet 4 is expelled to power shell 1.
