Description

Radiation fan

The utility model relates to radiator, is meant a kind of assembling of radiation fan and the improvement of structure thereof especially.

Progress along with science and technology, require accurate electronic product to have the high power running, but the powerful electronic product of power is easy to generate high temperature in the use, except making product not have the Security in the use, the situation that also causes the product component wear easily and decommission, therefore in most of electronic product, all has the design of radiation fan, the radiating effect when reaching the product use with this.

Radiation fan commonly used is installed on the mode of radiator such as Fig. 1-shown in Figure 2, end face at the housing 10 of radiator is formed with an opening 12, around it and be provided with plurality of fixed hole 14, for set firmly one with the fixed plate 16 of these opening 12 form fit, on the fixed plate 16 and be formed with one the fluting 18, its inner rim is provided with three draw-in grooves 20 that are the bending design, the top level of one motor apparatus 22 is arranged with three connection straps 24, the side front end of each connection strap 24 is formed with a protruding block 26, snap in the draw-in groove 20 and utilize the method for some glue that protruding block 26 is fixed in the draw-in groove 20 respectively protruding block 26, the top of motor apparatus 22 is fixedly arranged on the fixed plate 16, and this fixed plate 16 that is installed with motor apparatus 22 is locked on the fixed hole 14 of housing 32, then motor apparatus 22 places housing 10 inside, a sheathed fan 28 on motor apparatus 22, make fan 28 be subjected to the driving of motor apparatus 22 and rotate, wherein the bottom of fan 28 blades is to be the level design.Its major defect is:

This kind assembling mode needs by fixed plate 16 motor apparatus 22 to be located at housing 10 inside, except make the cost increase because of the increase of member, the reject ratio of assembling is promoted, thereby be easy to generate the situation that blade movement has some setbacks.

Main purpose of the present utility model is to propose a kind of package assembly improvement of radiation fan, reaches to make the assembling of fan easy, and has the purpose that reduces cost.

Another purpose of the present utility model is to propose a kind of radiation fan, by increasing the design of fan blade air draught, reach the purpose of the air output increase that makes fan.

The purpose of this utility model is achieved in that a kind of radiation fan, it is to be installed in the radiator, radiation fan comprises motor apparatus and fan group, it is characterized in that: the top of this motor apparatus have horizontal framework around evenly be provided with three contiguous blocks and be locked in the housing end face, this motor apparatus places enclosure interior; This fan group places the enclosure interior of this radiator to be sheathed on this motor apparatus, this fan group is made up of flabellum framework and plurality of vanes, this flabellum is connected with respectively around this flabellum framework, and an end of the contiguous flabellum framework of this blade bottom surface also is extended with oblique projection downwards.

Respectively be formed with the circular arc guide face between two blades of the periphery of this flabellum framework.The outer rim of the framework bottom surface of this motor apparatus has extended ring plate downwards, and when the upper shed of this framework corresponding housing was arranged at the housing end face, the inner edge of this ring plate next-door neighbour upper shed was around the upper end in the outside of fan group blade.Be equipped with an air baffle ring on the end face of the blade of this fan group or the bottom surface.This air baffle ring of being located at the blade bottom surface is the outside that is arranged at oblique projection.

Major advantage of the present utility model be have make fan assembling easily and have reducing cost and increase the effect of air output.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Embodiment 1

Consult Fig. 3-shown in Figure 4, radiation fan of the present utility model is to be installed in the radiator 30, the end face of the housing 32 of this radiator 30 and bottom surface are formed with a corresponding mutually upper shed 34 and a under shed (not shown) respectively, radiation fan comprises a motor apparatus 38, the design of its top tool one

horizontal framework

40,40 of framework evenly is provided with three contiguous blocks 42 on every side, make these framework 40 corresponding upper sheds 34 and contiguous block 42 on every side is locked in housing 32 end faces, motor apparatus 38 places housing 32 inside, the one fan group of being made up of flabellum framework 44 and plurality of vanes 46 48 makes to be sheathed on and is driven by it on the motor apparatus 38 and rotates, wherein, plurality of vanes 46 is connected with respectively around this flabellum framework 44, and an end of the contiguous flabellum framework 44 of blade 46 bottom surfaces also is extended with an oblique projection 50 downwards, to increase the air draught area of blade 46.

Above-mentioned radiation fan, be that motor apparatus 38 directly is fixedly arranged on the housing 32, assembling mode must place the design of enclosure interior to come conveniently and assembling easily motor apparatus by fixed plate than commonly used, and improve commonly used because of assembly program more, and the situation generation of blocking easily because of the fan blade that assembly failure caused easily or turning round and have some setbacks, and, therefore also has the advantage that reduces cost because the parts that the utility model adopted is less; In addition, be formed at the oblique projection of blade bottom, it is type or arc line type in line, and it be the design on plane than blade bottom commonly used, has the effect that increases blade air draught face, can make the air output increase of fan.

Embodiment 2

Consult shown in Figure 5ly, present embodiment to improve the water conservancy diversion effect of fan, makes its running efficiency that can effectively promote fan, and increases its radiating effect for respectively be formed with a circular arc guide face 52 between two blades 46 of the periphery of the flabellum framework 44 of said fans group 48; In the outer rim of framework 40 bottom surfaces of this motor apparatus 38 and extended a ring plate 54 downwards, the upper shed 34 that makes these framework 40 corresponding housing 32 is when being arranged at housing 32 end faces, this ring plate 54 can be close to the inner edge of upper shed 34, make this ring plate 54 to lower the air output of fan in the time of can preventing the fan running because of the adverse current in flow field around the upper end in the outside of fan group 48 blades 46.
