Abstract

The utility model discloses a cooling fan which uses the wind force to compel evaporation water to obtain wet cool air. The water evaporation array is composed of the materials whose capillarity function is vigorous, and the water contained in an upper water groove flows down and soaks into the water evaporation array through a water distributing interlayer to make the water evaporation array fully met; because of the large quality ratio of the surface, the utility model can make fully use of the air quantity of a fan to lead larger evaporation quantity and can ensure smooth air venting, and thus, the wet and cool air venting can be obtained. The cooling fan has the advantages of electricity saving, water saving, low noise, simple structure, low cost, and convenient maintenance; the utility model is suitable for the places of vast dry and heat areas in north parts in the country such as households, hospital wards, hotel guest rooms, offices, etc; besides, the utility model is particularly suitable for improving the living and working environments of oil field development employees in desert areas.

Description

Cooling fan with blowing water evaperation

The utility model relates to a kind of wind-force forced evaporation water and obtains cool breeze, has to make the moistening cool wind fan that has the sterilization function for expelling pests concurrently with fresh air.

Air conditioner absorbs heat when refrigerant gasifies in vaporizer, reaches the effect that a certain set environment temperature is reduced.Cold-producing medium after the gasification is compressed again, heat release, and heat distributes and become liquid again behind another environment, recycles.Air conditioner is owing to complex structure cost height, and consuming electric power is many, still can not most of at home families generally use.

With cooler refrigeration such as semiconductors still is cost with the consumed power.As Chinese invention patent 90105959.5 and 91100554.4 disclosed methods.

With water is that cooling medium obtains cool breeze, has to pay the water type air conditioner of pressing air draught, as Chinese utility model patent 88213579.1 disclosed methods; Or be the energy-conservation air conditioner of refrigerator with the surface by multiple seepage material, as Chinese utility model patent 90216208.4 disclosed methods; Or air blast Sunstroke preventing device such as Chinese utility model patent 91207702.6 disclosed methods that water is flowed down along impeller, or atomized water evaporative air cooler such as Chinese utility model patent 9121558.7 and 90206912.8 disclosed methods, make the water vaporating cooled air conditioner of water circulation with water pump, as Chinese utility model patent 89208034.5 disclosed methods.

These the deficiencies in the prior art parts are to expend more electric energy, and complex structure has increased cost of manufacture, or efficient is lower.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of more easy wind-force forced evaporation water to obtain the cool wind fan of pure and fresh moistening nice and cool air-out.

The purpose of this utility model is achieved in that the clear water of containing is flowed down by aperture in the upper flume of cool wind fan, go into via the orifice flow that matches with upper flume aperture position that four bandings close on the water distribution interlayer front plastic foil that porous water-storage material that plastic film bag coats makes, hold into and spread all over the porous material space, water infiltrates the water evaporation array that the tight with it absorbent material by capillary diversion effect is arranged that contacts is made by the many apertures that are provided with on the plastic foil of water distribution interlayer bottom surface again, because the water distribution effect of water distribution interlayer and water evaporation array are made material and had capillary diversion and retaining effect, it is fully moistening that the water that oozes uses the evaporation array down.Water evaporation array makes compactness but the surface area mass ratio is big, the fan that places box-shaped cool wind fan one end is sucked and is agitated the space of strong mobile blows air over array by air inlet, the water of array absorption is evaporated rapidly, the part heat content of hot-air is converted into steam latent heat, make the air-flow cooling, must pure and fresh wetting nice and cool wind at cool wind fan other end air outlet.

The utility model has following advantage:

1. flow can be controlled when the water in the upper flume was flowed down by aperture.Evenly infiltrate the water evaporation array that adopts the vigorous material of capillarity to make under the water distribution effect of water distribution interlayer, whole array still keeps wetting state when fan running at full capacity evaporation capacity is maximum.Lower flume only connects the water of depositing under oozing from array on a small quantity, owing to wherein contain dust, bacterium and other dirts that the array filtered air washes, will regularly release.So just saved the pump line system that makes the water circulation, can reach the wetting and pure and fresh purpose of air-out cooling with the water consumption of minimum.

2. water betides on the array that the vigorous material of capillarity makes, and the long-pending mass ratio of this array surface is big, and so the water disengagement area is big, the heat of vaporization of water is also big, thus fan blowing forced evaporation water to obtain moistening cool breeze be the main cause that air-out is felt nice and cool.In addition, water evaporation back water evaporation array temperature also reduces, and the exchange of the moving air array thermal that surface area is big therewith is the nice and cool Another reason of air-out.

3. the utility model only uses an electric fan, therefore its noise level is determined by the fan noise level, the reasonable disposition of material, size and the voidage of the air quantity of fan, water evaporation array, the wind that fan is agitated can make water evaporation as much as possible, guaranteeing again has the cool breeze of q.s to blow out, and reaches to consume the most effective cool effect of a certain amount of electric energy acquisition.

4. add a small amount of wetting agent in the water in the upper flume, the array that evaporates the water is not shrivelled, and capillarity is able to long term maintenance, has reduced the cost of manufacture of water evaporation array, and has prolonged its operating period.

5, can in the water of upper flume, add little air freshener, flavouring agent, bactericidal agent, agrochemical, can prevent that germ from growing, and makes it when obtaining cool breeze the effect that have seasoning concurrently, sterilize, wipes out the flies and mosquitoes on the water evaporation array of humidity.

By above narration, cool wind fan of the present utility model is simple in structure, power saving water-saving, noise are low, and working service is convenient, and diverse in function adapts to the numerous common people's level of consumption of present China, can be used for public situation such as family practice ward and office.

Concrete structure of the present utility model is provided by following examples and accompanying drawing 1.

Describe structure and working condition in detail below in conjunction with Fig. 1 according to the cool wind fan that the utility model proposes.

This cool wind fan comprises box-shaped casing 1, rear portion dress fan 2, steam array 3 over against water before the fan, the water of being contained in the tank 4 is flowed down by the aperture 5 of the adjustable throttle water yield, hold and be uniformly distributed in water distribution interlayer 6 more than the hole water-storage materials, the even infiltration of pore membrane tightly places the water under it to evaporate array 3 more than its bottom again, makes it fully moistening.When starting fan 2, air is entered by rear portion air inlet 7, and the air that flows makes the evaporation of its wetting water section through the space of water evaporation array 3 strongly, at the moistening nice and cool wind of air outlet 8 acquisitions of cool wind fan.

Earlier the delivery port in the lower flume 9 10 is opened venting sewage before using, again clear water is poured into upper flume 4, connect fan 2 power supplys and get final product.4～6 liters of upper flume volumes are gone up water at every turn and can be used continuously 3～5 hours, aperture 5 can be closed as not using, and turn off fan.As not closing aperture 5, then the water in the upper flume flows down and water can be evaporated array and rinse well.
