The invention provides a water-fetching ring of an axial fan, comprising an axial fan body, on which a hub combined with the driving shaft of a motor is arranged, wherein a plurality of fan blades are arranged and connected onto the outer peripheral surface surrounding the hub, the water-fetching ring surrounds the outer peripheral surface at the top part of the fan blades and is connected with the connecting part of each fan blade; a plurality of water-fetching projections are evenly distributed at a certain interval along the inner side surface of the water-fetching ring; along the inner side surface of the water-fetching ring, a water-guiding groove is arranged in each water-fetching projection; along one side of the water-guiding groove, a plurality of water-discharging grooves which are communicated with the water-guiding groove are arranged; and the water-discharging grooves are arranged in front of the water-fetching ring. The invention can lead the water-fetching ring to carry more cooling water and increase the water-fetching amount of the water-fetching ring; in addition, the invention can bring the water to a higher position, improve the water-fetching strength exerted on a heat exchanger so as to lead the water to be capable of penetrating the deep layer of the heat exchanger, and enhance the heat-exchanging performance of the heat exchanger.
Description
Technical field
The present invention relates to aerofoil fan, relating in particular to a kind ofly can increase the amount of fetching water under identical rotating speed, simultaneously, can take water to the more water ring of the aerofoil fan of high position.
Background technology
Generally, aerofoil fan is to receive the revolving force of external drive source such as motor etc. and rotate, and the machine of axially blowing air.It is not only applicable to household appliances such as electric fan, air conditioner and refrigerator, is widely used in multiple fields such as space shuttle and engine yet.
As shown in Figure 1, be a kind of existing aerofoil fan that is used for household appliances such as air conditioner and refrigerator, the center of this aerofoil fan is provided with the wheel hub 1 that combines with the driving shaft of motor, also is the pivot of aerofoil fan.Center on the outer peripheral face setting of wheel hub and be connected with several fan blade 2 with air-supply effect, these several fan blade 2 guide air and produce air-flow when aerofoil fan rotates.Around the outer peripheral face at fan blade 2 tops and the water ring 3 that is connected with each fan blade 2 top connecting portion, keeping at a certain distance away along the medial surface of water ring 3 is evenly distributed with several projections 4 of fetching water.During the aerofoil fan rotation, drive water ring 3 and projection 4 rotations of fetching water, and cooling water is got to the effect of landing low temperature on the heat exchanger.
During aerofoil fan work, rotate simultaneously in the driving shaft drive lower hub 1 and the fan blade 2 of motor, fan blade 2 guides air and produces air-flow when aerofoil fan rotates.Center on the water ring 3 and the also rotation simultaneously of projection 4 of fetching water of the outer peripheral face at fan blade 2 tops, and cooling water is got on the heat exchanger.Because the medial surface of water ring 3 is smooth ring bodies, can not store the cooling water of playing, when not taking cooling water to higher position, a part of cooling water has just flow down.Therefore, water ring 3 is not got to the cooling water of playing on the heat exchanger fully, has reduced the dynamics of fetching water.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that existing product exists, and a kind of water ring of improved aerofoil fan is provided, and it can increase the amount of fetching water of water ring under identical rotating speed.Simultaneously, can take water to more high position, improve the dynamics of fetching water.
The objective of the invention is to realize by following technical scheme.
The water ring of a kind of aerofoil fan of the present invention; Comprise the aerofoil fan body; The aerofoil fan body is provided with the wheel hub that combines with the driving shaft of motor, on the outer peripheral face of wheel hub, is provided with and is connected with several fan blade, around the outer peripheral face at fan blade top and the water ring that is connected with each fan blade connecting portion; Keep at a certain distance away along the medial surface of water ring and to be evenly distributed with several projections of fetching water; Fetching water along the medial surface of said water ring and at each is provided with the water guide groove between the projection, the water guide groove is arranged on the centre position of water ring medial surface, is provided with the drain groove that several are connected with the water guide groove in water guide groove one side.
Said drain groove is arranged on the front of water ring.
Said water guide groove and drain groove are one-body molded on the aerofoil fan body.
Beneficial effect of the present invention: the present invention makes water ring can carry more cooling water owing to adopt said structure, has increased the amount of fetching water of water ring; Simultaneously, can take water to more high position, make the water distribution of beating on heat exchanger more even.And, improved the dynamics of fetching water of beating on heat exchanger owing to increased drain groove in the water outlet direction water can unimpededly be derived, and make water can be penetrated into the deep layer of heat exchanger, increased the heat exchange property of heat exchanger.

Fig. 2 is a structural upright sketch map of the present invention.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Main label declaration among the figure:
1 wheel hub, 2 fan blade, 3 water rings, 4 fetch water projection, 5 water guide grooves, 6 drain groove.
The specific embodiment
Consult Fig. 2 and shown in Figure 3, the water ring of aerofoil fan of the present invention comprises: aerofoil fan body, aerofoil fan body are provided with the wheel hub 1 that combines with the driving shaft of motor, also are the pivots of aerofoil fan.Be provided with on the outer peripheral face of wheel hub 1 and be connected with several fan blade 2 with air-supply effect, these several fan blade 2 guide air and produce air-flow when aerofoil fan rotates.Around the outer peripheral face at fan blade 2 tops and the water ring 3 that is connected with each fan blade 2 connecting portion; Keeping at a certain distance away along the medial surface of water ring 3 is evenly distributed with several projections 4 of fetching water, and present embodiment is: the medial surface spaced set along water ring 3 has 5 projections 4 of fetching water.Aerofoil fan when rotation, the effect that drives water ring 3 and fetch water projection 4 rotations and cooling water got to landing low temperature on the heat exchanger.
Fetching water along the medial surface of water ring 3 and at each is provided with water guide groove 5 between the projection 4, water guide groove 5 is arranged on the centre position of water ring 3 medial surfaces.Water guide groove 5 can prevent that the water of playing from flowing out too early, can carry more cooling water, has increased water ring 3 amounts of fetching water.
Be provided with the drain groove 6 that several are connected with water guide groove 5 in water guide groove 5 one sides, the water in the water guide groove 5 flows out through drain groove 6.Drain groove 6 is arranged on the front of water ring 3, and the wind that fan blade 2 is seen off will blow on the heat exchanger from the water that drain groove 6 flows out, and has increased the dynamics of fetching water of beating on heat exchanger.
