Abstract

The utility model relates to a radiating device for electronic appliances, which can solve the problem of radiation efficiency, the utility model comprises an air pipe body and at least one flow deflector, and the air pipe body is a hollow frame body and is provided with an air inlet and an air outlet which are communicated. The utility model is characterized in that position holes are arranged on the peripheral pipe wall of the air outlet, and each set of two opposite position holes can be arranged at a circular arc position point which takes the two position holes as shaft center and takes the preset width as imaginary radius, and the circular arc position point is at least provided with the other corresponding position hole which can be matched with the circular arc position point. The preset between space width points at both sides of the flow deflector are respectively convexly provided with pivot posts which can be respectively inserted into the position hole corresponding to the air pipe body, and the pivot posts can change the included angle between the air pipe body and the pivot posts. The utility model can be used in computers, etc.

Description

The air-guide duct apparatus of radiator fan

The utility model relates to radiator fan, refers in particular to the guide duct that is used for the radiator fan on computer or the power supply unit.

The existing radiator fan that is used for computer, though it brushes that direction has can be in casing, to produce convection current, make other each electronic installation that is not equipped with radiator also equally can this radiator fan of mat and obtain certain thermolysis, though but owing to radiator fan brush direction inwardly but the effect of do not have concentrating let alone to brush everywhere, not only can make unnecessary the blowing to hollow and do not have in the space of any electronic installation of too much air-flow, and often make the electronic installation of the heat radiation that really should obtain to fill part can't obtain efficiently radiates heat, the part that more do not need on the contrary to dispel the heat may but continue and be brushed strong, that is produce unbalancedly, cause heat radiation not smooth.

The purpose of this utility model provides a kind of air-guide duct apparatus of the radiator fan perfect, that efficient is higher that can make it to dispel the heat.

The purpose of this utility model is achieved in that the air-guide duct apparatus of radiator fan, it comprises: an airduct body and at least one baffler, the airduct body is a hollow framework and air inlet and the air outlet that connects is arranged, it is characterized in that: offer location hole on the tube wall of its air outlet periphery, and relative two location holes of each group all can with this two location hole be axle center and be that the arc position place of imaginary radius has at least another can corresponding location hole with matching with the preset width; Baffler two side spacing preset width places convex with respectively and can be plugged in the pivot post that changes angle between itself and airduct body in the airduct body corresponding positioning hole respectively.

Above-mentioned design utilizes the setting of this frame post, and makes baffler can change angle between itself and airduct body, with direction and the size that changes gas channel, thereby reaches the effect that the radiator fan heat radiation is perfect, improve the efficient of loosing.

Below by drawings and Examples the utility model is described further again:

Fig. 1 is the utility model perspective exploded view;

Fig. 2 is the utility model side-looking generalized section;

Fig. 3 is the utility model user mode schematic diagram;

Fig. 4 is the utility model part stereo appearance figure;

Fig. 5 is the utility model part cross-sectional schematic;

Fig. 6 is another use schematic diagram of the utility model;

As Figure 1-3, the utility model comprises: an airduct body 1 and at least one baffler 2, airduct body 1 is a hollow framework and the air inlet 10 and air outlet 11 that connects is arranged, it is characterized in that: offer location hole 12 on the tube wall of its air outlet 11 peripheries, and relative two location holes 12 of each group all can with this two location hole 12 be axle center and be that the arc position place of imaginary radius has at least another can corresponding location hole 12 with matching with the preset width; Baffler 2 two side spacing preset width places convex with respectively and can be plugged in the

pivot post

20,21 that changes itself and 1 angle of airduct body in airduct body 1 corresponding positioning hole 12 respectively.That is when baffler 2 the place aheads two pivot posts 20 are hubbed on airduct this stops two relative location holes 12 in 1, rear two pivot posts 21 must have in addition, and two corresponding positioning hole 12 can make 1 of baffler 2 and airduct body form a special angle and cause a specific gas channel for its clamping, for example location hole 12a can find location hole 12a ' corresponding with it, location hole 12b has location hole 12b ', location hole 12c has location hole 12c ', location hole 12d has location hole 12d ', location hole 12e has location hole 12e ', location hole 12f has location hole 12f ', and location hole 12g has location hole 12g ' corresponding with it.

Shown in Fig. 4-6, radiator fan 3, wherein air outlet 11 peripheries of airduct body 1 have grab 13, and wherein, air inlet 10 peripheries of airduct body 1 have grab 14.Even also this airduct body 1 is except that can also snapping onto with grab 13 on the dividing plate 4 default button holes 40 in its air outlet 11 ends in air inlet 10 ends are fixed on the electronic installation 5.So the angle adjustment through baffler 2 changes, and can improve the radiating efficiency of radiator fan 3 greatly, improves heat dissipating state.
