Description

The combined type fluid power plant

Technical field

The utility model relates to a kind of combined type fluid power plant, relates in particular to a kind of combined type fluid power plant with aial flow impeller and receded disk impeller combination utilization.

Background technique

Along with the rapid vigorous growth of Information technology, computer has become instrument indispensable in the daily life.But because computer is to be assembled by electronic component, operation adds shortcomings such as the computer volume is little, ventilation is difficult for for a long time, is easy to produce high temperature.If the radiating efficiency of computer is bad, will cause the computer shortening in working life, more serious even cause irreparable damages such as data loss.Therefore, must be strict especially for the design of computer-internal radiation fan, make it can in limited space, reach best radiating efficiency.

In order to improve the blast of radiation fan, adopt at least two axial-flow type radiator fans to connect usually and improve the blast that impeller can produce.But because centrifugal radiation fan is an air inlet through hollow shaft, therefore the side direction air-out can't improve blast by the mode of a plurality of fan series connection, causes centrifugal radiation fan to be restricted on the occasion of practical application.

The design artificially improves and solves the defective that exists in the above-mentioned prior art, through concentrating on studies and cooperating theoretical utilization, proposes a kind of reasonable in design and can effectively improve the utility model of above-mentioned defective finally.

The content of model utility

Main purpose of the present utility model is to provide a kind of combined type fluid power plant, and aial flow impeller and receded disk impeller combination utilization are improved throughput and the blast that receded disk impeller can produce.Simultaneously, utilize the different design of runner width, increase the flow velocity of flowing medium, increased the practicability of receded disk impeller.

In order to achieve the above object, the utility model provides a kind of combined type fluid power plant, comprises one first power unit, one second power unit and a fluid passage that is communicated with between first and second power unit.This first power unit has an aial flow impeller; This second power unit has a receded disk impeller; This fluid passage from first power unit to second power unit by wide to narrow variation.Thus, the impeller by first power unit sucks extraneous air-flow in the fluid passage, by second power unit gas is discharged again, has increased throughput and blast, thereby has reached better heat radiation purpose.

Embodiment

In order to make those skilled in the art further understand feature of the present utility model and technology contents, see also followingly about detailed description of the present utility model and accompanying drawing, accompanying drawing only provides reference and explanation, is not to be used for limiting the utility model.

Fig. 1 and Fig. 2 are respectively the utility model first embodiment's combination schematic representation and cross-sectional schematic.As depicted in figs. 1 and 2, the utility model provides a kind of combined type fluid power plant, is used for driving gas or liquid as transmitting medium.In embodiment of the present utility model, fluid power plant 1 uses as a kind of radiation fan.Fluid power plant 1 comprises that one first power unit 10, one second power unit 11 and one are communicated with the fluid passage 12 11 of first power unit 10 and second power units.Wherein:

First power unit 10 is common axial-flow type radiator fan, the aial flow impeller 101 that has a housing body 100 and driven by gear unit (not shown)s such as motors.Impeller 101 is arranged on the hollow part in the housing body 100, makes medium that first power unit 10 transmitted along axially the entering of impeller 101, and along the axial outflow of impeller 101.Second power unit 11 is common centrifugal radiation fan, has the receded disk impeller 110 that is driven by gear unit (not shown)s such as motors, and the medium that impeller 110 is transmitted second power unit 11 axially enters along it, and radially flows out along it.Because axial-flow type radiator fan and centrifugal radiation fan are known technology, therefore no longer given unnecessary details for its detailed contexture.

Fluid passage 12 is formed in the housing 13.In the present embodiment, housing 13 is strip, has the two end part 130,131 that communicate with its inside.One end, 130 openings of housing 13 are bigger, first power unit 10 is embedded wherein, and extraneous air-flow (medium) can be inhaled in the housing 13 by the impeller 101 of first power unit 10.The other end 131 of housing 13 is positioned at housing 13 side direction and opening less (as shown in Figure 2), the air-flow in the housing 13 can be discharged from the other end 131 of housing 13 when second power unit 11 is arranged in the housing 13.

In sum, fluid passage 12 is formed in the housing 13 and is communicated with between first power unit 10 and second power unit 11, and fluid passage 12 is surrounded by the internal face of housing 13 and a guiding face 120 and forms.It is one skewed that guiding face 120 is between first power unit 10 and second power unit 11, and fluid passage 12 is by wide to narrow and be streamline and change to second power unit 11 from first power unit 10.Above second power unit 11, offer a through hole 121, make inflow media flow wherein unimpeded.

In addition, guiding face 120 also can be a curved surface shape, thus the obstruction when reducing the medium circulation.Form by above-mentioned structure, can obtain combined type fluid power plant of the present utility model.

The utility model has multiple different mode of execution in force.As shown in Figure 3, a plurality of fluid power plants 1 can be merged and use side by side, and apply in a flexible way according to concrete actual state.

Fig. 4 and Fig. 5 are the utility model second embodiment's combination schematic representation and cross-sectional schematic.As shown in Figure 4 and Figure 5, make housing 13 be one " L " font, can be applicable to thus that inlet air and air-out have height difference or not in the occasion of same horizontal plane.

Fig. 6 is the utility model the 3rd embodiment's a combination schematic representation.As shown in Figure 6, will use behind fluid power plant 1 half-twist.Therefore other structure and first embodiment and indifference repeat no more.

Combined type fluid power plant of the present utility model can increase throughput and the blast that receded disk impeller can produce by assisting of axial center type impeller, obtains better radiating effect.

In sum, combined type fluid power plant of the present utility model can reach the application target of expection, solved the defective that exists in the prior art simultaneously, has practicability, novelty and creativeness, meet the requirement of utility application fully, file an application according to Patent Law, would like to ask detailed survey and authorize the utility model patent, to ensure the design people's right.

The above is a preferred embodiment of the present utility model only, is not so promptly limits claim of the present utility model, and the equivalent structure transformation that every utilization specification of the present utility model and accompanying drawing content are done all in like manner is included in the scope of the present utility model.
