Abstract

The utility model relates to a vane cooling type cooling fan. Compared with the existing cooling fan, the utility model has the advantages of simple structure and low cost. A layer of water absorption materials are covered on fan blades (2), and the water of a water box enters an annular flow passage (10) and a radial flow passage (11) through the water pipe. The utility model has the same working principle as a centrifugal water pump, the water pumped into the radial flow passage (11) is guided to flow into the water absorption layer of the fan blades though a short pipe (12) when the fan blades rotate. The water is quickly vaporized on the rotary blades, and cooling wind can be fanned out because the water absorbs the heat and cools down the wind. So the utility model has good heatstroke prevention and temperature lowering effect when the ambient air temperature is higher than 35 DEG C.

Description

Blade cooled thermantidote

The utility model is a kind of thermantidote.

Existing thermantidote structure is comparatively complicated, moves, and places all inconvenient.Profile is not attractive in appearance yet, and very strange concerning China consumer, is difficult to be accepted by China consumer.The utility model thermantidote is simple in structure, only Duo a water system than the common electrical fan structure, it is all very convenient that it moves placement, profile and common electrical fan are basic identical, can avoid China consumer that this series products of thermantidote is repelled sense because of the strange distrust that causes, to be familiar with believable electric fan image wedging conventional fan market, this novel thermantidote is except that water system and fan blade in addition, other structure all structure with electric fan is identical, therefore can make full use of the process equipment that electric fan produces house, save a large amount of development and operation funds.

The purpose of this utility model is the household appliances that the cooling of a kind of anti-administration is provided for vast consumption.

The utility model is finished as follows: have an annular runner and several roads radial flow path in the fan blade sleeve of the utility model thermantidote, the two communicates, perhaps stretch out rotating shaft place a sleeve is set, the radial flow path that its inside has annular runner and communicates with it at fan electromotor.Annular conduit one end of one wound motor rotating shaft stretches in the annular runner, and the two can rotate relatively, and annular conduit is communicated with a water tank by hose again.During fan running, make the water of water tank flow into annular conduit and then flow into annular runner and radial flow path through hose, identical with dried up formula pump working principle, water quickens to flow out runner in the radial flow path internal cause action of centrifugal force of rotation, in runner, form negative pressure, under the atmospheric pressure effect, the water in the water tank is just taken out diffluence outside runner co-current flow road radially continuously.The opening part of radial flow path is connected with a short tube with flat opening.Characteristics of the present utility model are to cover on the leaf blade layer absorbent material is arranged, the flat opening of aforementioned short tube is pressed close to root of blade and is stretched under its water accepting layer, like this in the middle of the operation of this thermantidote, the water that flows out from radial flow path flows in the water accepting layer of leaf blade through the opening of short tube, adsorbed by water accepting layer and to around diffusion, at centrifugal action, water in the water accepting layer flows to vane tip simultaneously, diffusion, whole blade is moistening like this, blade is when the rotation sweep air, speed with respect to air is very high, be equivalent to air and flow through moistening fan blade surface fast, make the water rapid evaporation of fan blade water accepting layer, absorb the heat of surrounding air, thereby make the wind of fan blade fan-out be lower than environment temperature.Be to strengthen the diffusion effect of water on fan blade, can take on fan blade recessing or fan blade be made technological measure such as palisade, (between grid) insert the water imbibition material between groove, and the flat opening of short tube is stretched into (between grid) between groove.The utility model water system also has another to finish mode, neither use annular conduit, but the radially duct of on machine shaft, opening the central axial bore road and communicating with it, central axial bore road in the rotating shaft is connected with hose, radially the duct communicates with annular runner, water in the water tank has just flowed into annular runner and radial flow path through rotating shaft like this, flows in the blade water accepting layer through the flat opening of short tube again, finishes the suction task.This structure is fit to the utility model is made the thermantidote of box fan form.Adopt above-mentioned fan blade modular construction and water system, the utility model can be made into the thermantidote of stand fan, box fan, desk fan or the like various ways.

The utility model has only changed blade structure and has increased by a cover water system on fan structure, but is better than electric fan energy fan-out cold wind, and it is simple with at present traditional thermantidote comparative structure, and cost is low, is a kind of thermantidote with electric fan advantage.Adopt three embodiment of as detailed below, can make full use of process equipment, parts and the production line of existing ripe setting.

Below in conjunction with accompanying drawing the utility model is described in further detail.
