Abstract
The present invention relates to a shell base of an axial flow radiator fan, and aims to provide a heat radiation apparatus part increasing integral air input, reduces noise, maintains inner air pressure, and ensures air inlet efficiency and air outlet efficiency. The shell base of an axial flow radiator fan comprises an annular wall for containing a fan motor. An air inlet and an air outlet are formed on the annular wall. A plurality of axial notches arranged in the axial direction are formed on the annular wall. The widths of the axial notches near the air inlet are larger than those of the axial notches near to the air outlet so that the diameter of the axial notches is expanded towards the air inlet side, and is reduced towards the air outlet side.
Description
Technical field
The invention belongs to the sink parts, particularly a kind of shell block of axial flow radiation fan.
Background technique
The axial flow type heat elimination fan of commonly using, as U. S. Patent the 6th, 132, No. 171 ' blower and shell block model method thereof (Blower and Method for Molding Housing Thereof) ' patent of invention, the shell block of heat-dissipating fan comprises ring wall, substrate and rotor.
Ring wall is generally rounded, and is positioned at the inlet air side of shell block.
Substrate is rectangular, and is positioned at the air side of shell block.
Rotor is provided with several pieces blades, and is located in the ring wall.
Ring wall is formed by the axial stacked arrangement of several ring flat-plates, then forms radially notch of long and narrow several between each two adjacent ring flat-plate.
When rotor rotation, the blade of rotor can be via the air-flow around the notch suction casing seat radially, to increase whole air inflow.
Yet, because radially the radial air flow direction that sucks of notch almost forms 90 ° of right angles with the axial flow direction of wind inlet, thereby, when air-flow at the blade of rotor and radially between the notch when mobile, it very easily forms sinuous flow and flow-disturbing.Moreover when if radially the width of notch is excessive, it may reduce air-flow pressurized effect in the ring wall relatively, thereby causes actual wind dispelling efficient not as expection.
The axial flow type heat elimination fan that another kind is commonly used, as U. S. Patent the 6th, 710, No. 486 ' the shell block structure (Housing Structure for a Heat-Dissipation Fan) of heat-dissipating fan ' patent of invention, the shell block of heat-dissipating fan comprises ring wall, composition board and rotor.
Ring wall further selects to form several long and narrow axial notch.
When rotor rotation, the blade of rotor flows to consistent air-flow to suck with the shell block wind inlet via axial notch.Though shell block can utilize axial notch to increase air inflow, reduce with wind inlet flowing to inconsistent probability simultaneously relatively, to reduce noise.But, because axial notch all forms consistent bore width by the inlet air side to the air side, therefore, when rotor sucks lateral airflow via axial notch, it may suck the air-flow of just having been exported by the shell block exhaust outlet by the position of the nearly air side of axial notch, so that disperses whole output gas flow.Moreover when excessive as if the width of axial notch, it still may reduce air-flow pressurized effect in the ring wall relatively, thereby causes actual wind dispelling efficient not as expection.Therefore, it is necessary further to manage to improve the structure of commonly using radiating fan casing seat really.
Summary of the invention
The purpose of this invention is to provide a kind ofly increases whole air inflow, reduces noise, keeps air pressure inside, guarantees the shell block of the axial flow radiation fan of air intake efficiency and air-out efficient.
The present invention comprises the ring wall that is installed with fan motor; Ring wall is formed into air port and exhaust outlet; Form several axial notch of axially-aligned on the ring wall, the nearly wind inlet width of axial notch makes axial notch form hole enlargement and form undergauge to the air side to the inlet air side greater than the width of nearly exhaust outlet.
Wherein:
Axial notch is trapezoidal, taper or trumpet-shaped inclination hole enlargement.
One side of axial notch forms so as to importing the water conservancy diversion inclined-plane of lateral airflow glibly at wind dispelling direction front end.
Toward nearly air-out oral-lateral width at least two group axial notch decrescence are set by nearly inlet air oral-lateral on the ring wall.
Form reinforcement gilled rings at least between the two adjacent groups axial notch of two group axial notch so as to stiffener rings wall construction intensity.
Nearly wind inlet side shaft is arranged with to the notch inwall and forms the extension breach that is communicated to the ring wall wind inlet.
At least two group axial notch form conical in shape jointly.
At least two group axial notch form the corresponding setting of axioversion jointly, so that smooth importing lateral airflow.
Ring wall exhaust outlet outward radial extends to form at least one composition board for fixing assembling.
Because the present invention comprises the ring wall that is installed with fan motor; Ring wall is formed into air port and exhaust outlet; Form several axial notch of axially-aligned on the ring wall, the nearly wind inlet width of axial notch makes axial notch form hole enlargement and form undergauge to the air side to the inlet air side greater than the width of nearly exhaust outlet.When the axial flow radiation fan motor operation in the shell block that is incorporated into axial flow radiation fan of the present invention, fan motor will be simultaneously by wind inlet and axial notch suction stream outer gas stream to unanimity, and can guarantee that by the inlet air side hole enlargement shape of axial notch fan motor can suck the lateral airflow of extra and capacity, will increase whole air inflow; Air-out side undergauge shape by axial notch also helps suitably sealing ring wall, make ring wall 10 inner tendencies form the air-flow pressurized effect, to keep higher discharge pressure of fan, and help avoiding the unexpected air-flow of just having exported that sucks of axial notch, thereby the energy active zone is every the shell block axial notch of axial flow radiation fan of the present invention and the air-flow of exhaust outlet by ring wall 10 exhaust outlets; Can guarantee whole inlet air efficient of the present invention and air-out efficient, and prevent to produce sinuous flow, flow-disturbing and turbulent flow, to reduce the noise of inlet air and air-out.Not only increase whole air inflow, reduce noise, keep air pressure inside, and guarantee air intake efficiency and air-out efficient, thereby reach purpose of the present invention.
