Abstract
The utility model discloses an axial fan for a heat-pump water heater. The axial fan comprises a hub and a plurality of blades, and the hub and the blades are of an integral structure. Blade included angles are 28 degrees. The axial fan is further characterized in that a circle of bosses protruding upwards are arranged at the combination positions of the hub and the blades, a protruded rib is arranged at the root of each blade to be connected with a corresponding boss, and the integral strength of the fan is increased. The number of the blades is an odd number, so that resonance is avoided when the fan rotates at high speed, and blade fracture is effectively avoided. The hub and the blades are aluminum alloy components. The axial fan for the heat-pump water heater is low in noise and large in air exhaust amount and effectively improves heat exchange rate of the heat pump water heater.
Description
Technical field
The utility model relates to a kind of axial fan, especially a kind of heat pump water heater axial fan.
Background technique
Some heat pump water heater fans are in the market plastic article, and blade tilt is generally 23 °.This fan is cheap, manufactures simply, thereby is widely applied.But this fan in actual use noise is large, and exhaust air rate is little, and blade easily ruptures, directly affect the heat transfer effect of heat pump water heater, cause complete machine energy consumption large, affected user satisfaction.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of low noise, the heat pump water heater axial fan that exhaust air rate is large.
The utility model is achieved through the following technical solutions technical goal.
Heat pump water heater axial fan, comprises wheel hub and several blade, and described wheel hub and blade are overall structure; Its improvements are: the blade tilt of described blade is 28 °.
In said structure, the boss that described wheel hub and blade junction have a circle to raise up, the root of each blade all has the muscle of a projection to be connected with boss.
In said structure, described blade quantity is odd number, and preferred amount is 5.
In said structure, described wheel hub and blade are aluminium alloy elements.
The utility model compared with prior art, has following good effect:
1. blade tilt changes 28 ° into by 23 °, has increased the flow velocity of air, has significantly improved exhaust air rate.
2. the muscle of the boss on wheel hub and blade projection has increased the intensity of fan.
3. aluminum-alloy fan weight is lighter, and wall thickness is even, and slow-roll stabilization during work effectively lowers the vibration causing because wall unevenness is even, thereby reduces noise.
4. blade quantity is odd number, can avoid fan when running up, to produce resonance, thereby causes blade cannot bear for a long time the fatigue that resonance produces, and finally occurs the situation of leaf destruction.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Heat pump water heater axial fan shown in the drawings, is aluminum-alloy fan, comprises wheel hub 1 and 5 blades 2, and wheel hub 1 and blade 2 are overall structure; The blade tilt of blade is 28 °; The boss 4 that wheel hub 1 and blade 2 junctions have a circle to raise up, the root of each blade 2 all has the muscle 3 of a projection to be connected with boss 4, has increased the bulk strength of fan.
