Abstract

An improved heat radiation fan casing base is composed of a base, a motor and a fan blade body, wherein one side of the base is provided with a bracket, the motor is arranged in the center of the bracket, the fan blade body is connected with the motor in a shaft way and can rotate, and an air guide inlet and an air exhaust outlet on the periphery of openings on two sides of a base accommodating chamber are inclined and expanded outwards and can be used for sucking larger air inlet quantity; the air guide inlet and the air exhaust outlet on the periphery of the opening on the two sides of the base accommodating chamber are inclined and expanded outwards, so that the air inlet volume is large during suction and exhaust, and the opposite air inlet volume can be smoothly guided by the inclined edge during air exhaust to reduce the temperature and cool.

Description

The radiation fan housing pedestal of tool improvement

Technical field

The utility model relates to the radiation fan housing pedestal of a kind of tool improvement, and the putting chamber both-side opening periphery that is meant its pedestal especially is for extending out the hypotenuse shape, but makes the smooth and easy average mark cold scattering sink but that reaches of air draft water conservancy diversion.

Background technique

Generally be applied to the radiation fan in computer main, the server power supply supply, the putting chamber that has a circular aperture in its shell, Circularhole diameter in this putting chamber is all identical, therefore make the fan blade body when spinning movement, suction air volume is less because of the opening that is subject to putting chamber, thereby suction air volume is limited; And when air draft because putting chamber has straight inwall, the air quantity of make discharging can be concentrated a source to discharge, the relative side that can't effectively diffuse to is done the larger area heat radiation, be with, its actual radiating effect is not good enough, is not inconsistent actual user demand.

Summary of the invention

The purpose of this utility model provides a kind of radiation fan housing pedestal of tool improvement, the wind guiding inlet of this pedestal putting chamber both-side opening periphery and wind exhausting outlet are for being inclined external expanding shape, can be for sucking the bigger air quantity of going into, relative when air draft, can guide the air quantity heat radiation smoothly, thereby can reach and have the good cooling cooling effect by its hypotenuse.

The utility model is elaborated with instantiation below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is the utility model stereoscopic figure;

Fig. 2 is the utility model exploded perspective view;

Fig. 3 be another angle of the utility model pedestal look stereoscopic figure;

Fig. 4 be according to the cutting line of the 4-4 of Fig. 3 and arrow direction look sectional drawing.

Drawing reference numeral explanation: 1 pedestal; 11 wind guiding inlets; 12 wind exhausting outlets; 13 supports; 14 putting chambers; 2 motors; 3 flabellum bodies.

Embodiment

Referring to Fig. 1 to Fig. 3, radiation fan housing pedestal of the present utility model mainly is to be made of pedestal 1, motor 2 and flabellum body 3, and wherein pedestal 1 one sides are provided with support 13, and support 13 central authorities send out and put motor 2, and flabellum body 3 is coupling with motor 2 and turns.

The wind guiding inlet 11 and the wind exhausting outlet 12 of these pedestal 1 putting chamber 14 both-side opening peripheries are inclined external expanding shape (referring to shown in Figure 4), the last wind guiding inlet 11 of this pedestal 1 reaches wind exhausting outlet 12 down, it is relative bell mouth shape, it all has the hypotenuse that extends out up or down, can be for sucking the bigger air quantity of going into, the relative air quantity of can being guided smoothly by its hypotenuse when air draft dispels the heat.

Therefore, the utility model can effectively dispel the heat by the improvement to base shell, and need not increase fan is set.

Claims

1, a kind of radiation fan housing pedestal of tool improvement comprises pedestal, motor and flabellum body, and wherein pedestal one side is provided with support, and support central authorities are for being provided with motor, and flabellum body and motor are coupling and turn; It is characterized in that:

The wind guiding inlet and the wind exhausting outlet of this pedestal putting chamber both-side opening periphery are inclined external expanding shape, for sucking the bigger air quantity of going into, guide the air quantity heat radiation smoothly by its hypotenuse when air draft.
