Abstract

An air direction and fluid pressure control device includes at least one fan with an inlet and an outlet and one frame body connected with the said fan. On both sides of the frame body are separately formed at least one first bevel and at least one second bevel. In the frame body is set a middle-set part and a passageway is formed between the middle-set part and the frame body, where the fluid can flow. The second bevel side is larger than the first bevel side of the passageway, so the fluid pressure can be controlled. The invention can also control the air direction.

Description

Wind fluid pressure controller

Technical field

The present invention relates to a kind of wind fluid pressure controller, particularly a kind of wind fluid pressure controller that is arranged in fan outlet or entrance.

Background technique

Along with the renewal day by day of electrical assembly, when speed, usefulness, power each side promote, also bring heating problem.

The electrical assembly that high temperature is sent in more common meeting is generally the high power electronic assembly; at a high speed central processing unit (CPU) for example; if the heating element of this class does not leave heat energy fast; will make the large heavy discount of its usefulness even can have influence on the life-span of assembly; for the high-power electrical assembly that makes this class can be brought into play its due usefulness; and increase service life, usually can pay close attention to the problem of its heat radiation.

In addition, see also Fig. 1, be general existing fan, include a fan frame 11 and be hubbed at the interior impeller 12 of fan frame 11, wherein said fan frame 11 both sides are formed with entrance 111, outlet 112 separately, and be provided with hub seat 113, and described impeller 12 includes wheel hub 121, and along wheel hub 121 side faces outward extending flabellum 122 radially, and then impeller 12 is hubbed on the hub seat 113 of fan frame 11, flow by its flabellum 122 draw fluid when impeller 12 rotates, entered by the entrance 111 of fanning frame 11, then flowed out by outlet 112.

But above-mentioned this modus operandi has its problem place, and fluid is entered by entrance 111, is flowed out by outlet 112, this a kind of fluid directly advances the mode that directly goes out, because fluid consumes in flowing, cause the pressure of fluid effectively to promote, and then can't show its heat dissipation.

So, because above-mentionedly commonly use every shortcoming that product derive, the invention of this case is artificially promoted this case and is more reached perfection, then exhaust its intelligence, to be engaged in described industry experience for many years, concentrate on studies and innovated improvement, successfully this part wind fluid pressure controller case is completed in research and development finally, is the invention that a tool effect is promoted in fact.

Summary of the invention

The object of the present invention is to provide a kind of wind fluid pressure controller that promotes or reduce hydrodynamic pressure.To achieve these goals, the technical solution used in the present invention is: a kind of wind fluid pressure controller, include at least a fan with entrance and outlet, and a framework that is connected with described fan, wherein:

Described framework both sides are formed with respectively at least one the first cut, at least one the second cut, in framework, tool is provided with at least one mid-section that is gradually-reducing shape of extending from the first cut side towards the second cut side, be formed with the runner for Fluid Flow in A between described mid-and framework, and greater than the first cut side, described runner is shape from small to large to described runner from the first cut towards the second cut in the second cut side.

Characteristic on above-mentioned purpose of the present invention and structure thereof and function will be explained according to appended graphic preferred embodiment.

Embodiment

The invention provides a kind of wind fluid pressure controller, Fig. 2 to Fig. 8 is the present invention's the first preferred embodiment, see also Fig. 2 to shown in Figure 5, the present invention includes a fan 21 and a framework 22 at least, wherein said fan 21 includes fan frame 211 and impeller 212, described fan frame 211 both sides tool respectively are provided with an entrance 2111, an outlet 2112, and are provided with an impeller seat 2113 in outlet 2112 sides and are pivoted for described impellers 212.

Described framework 22 both sides are formed with respectively at least one the first cut 221, at least one the second cut 222, the interior structure of framework 22 is established and is formed with at least one mid-223 of being gradually-reducing shape from the first cut 221 sides towards the second cut 222 sides extensions, described mid-223 and 22 of frameworks are formed with can be for the runner 224 of Fluid Flow in A, and described runner 224 is because of the convergent kenel of mid-223, described runner 224 is from the first cut 221 towards the second cut 222 shape from small to large, then the second cut 222 side correspondences of described framework 22 is arranged in entrance 2111 sides of fan 21.

The drive fluid is entered by runner 224 by the first cut 221 of framework 22 when described impeller 212 start, and the second cut 222, again via the entrance 2111 of fan 21, flowed out by outlet 2112, fluid is because being subjected to the variation from small to large of described runner 224, the flow velocity boost in pressure that slows down, pressure rise when causing fluid to be flowed out by outlet 2112, and boost in pressure causes the resistance of fan 21 larger, and then improving radiating effect.

Please consult again shown in Figure 6, outlet 2112 sides that the first cut 221 sides of framework 22 of the present invention connected fan 21, controllable flow body pressure increases and then improving heat radiation efficiency, and tool control direction of flow reduces the stagnant area at mid-223 rears when the second cut 222 flows out in centralized.

Please consult again shown in Figure 7, entrance 2111 sides that the first cut 221 sides of framework 22 of the present invention connected fan 21, and when flow during via the runner 224 that diminishes greatly, flow velocity speeds pressure to be reduced, pressure decreased when causing fluid to be flowed out by outlet 2112, and the generation of pressure decreased and then minimizing noise.

Please consult again shown in Figure 8, outlet 2112 sides that the second cut 222 sides of framework 22 of the present invention connected fans 21, controllable flow body pressure decreased, and then reduce the generation of noise, and control fluid and shed outward when the first cut 221 flows out, enlarge the heat radiation scope.

Please consult again shown in Fig. 9 A, Fig. 9 B and Fig. 9 C, described mid-223 can present different kenels by the first cut 221 sides towards the second cut 222 side convergents, mid-its vertical profile of 223a as shown in Fig. 9 A looked is Hexagon, as described in perhaps as shown in Fig. 9 B, mid-223b one end is to protrude the first cut 221 sides, or as described in as shown in Fig. 9 C, mid-223c one end is lower than the first cut 221 sides, presenting all of above-mentioned three kinds of kenels can have the control change in fluid pressure, reaches the characteristic that reduces noise and control wind direction.

please consult again and Figure 10 shows that the present invention's the second preferred embodiment, its overall structure is roughly identical with last embodiment with function and enforcement kenel, represent in this omission identical components explanation and reference character, and repeat no more it and implement kenel, and difference is in the present embodiment: be provided with at least one quiet wing 225 in described framework 22 and connect framework 22 inwalls and mid-223, the described quiet wing 225 is arranged in runner 224, make the pressure difference of fluid increase by described at least one quiet wing 225, and then improving heat radiation efficiency, and the characteristic of the generation of minimizing noise and control wind direction.

The above is only better feasible embodiment of the present invention, and the variation that such as utilizes the above-mentioned method of the present invention, shape, structure, device to do all should be included in the claim scope of this case.
