Figure 16 is this air-cooling fan electrical equipment speed control switch line chart
As shown in Figure 15, when the electric fan high speed rotating, pressure distribution is remarkable variation before and after the fan, and fan rear portion static pressure PjX approximates the negative pressure value of-25 column with occurring, simultaneously as shown in Figure 5, and because of flabellum is airfoil, according to Bernoulli's fluid principles; A negative pressuren zone and negative pressure peak value will appear in the top on its E-E section, allow the negative pressure peak point over against the air outlet 55, so total negative pressure value at 55 places, air outlet just equals the superposition value of two negative pressure peak values among Fig. 6 and Figure 15, centrifugal action when gas molecule is subjected to the dead axle high speed rotating in the hollow in addition flat tube 16, so make air outlet 55 produce comprehensive swabbing effect, just as extraction pump, gas in evaporation tank 4 and 5 is outwards extracted out continually, transient equiliblium occurred with air outlet 55 place's static pressures until evaporation tank 4 and 5 internal air pressures.Like this, because step-down can make evaporation rate accelerate, evaporation then produces the principle of decalescence, thus this air-cooling fan when implementing general air-supply, the while is auxiliary refrigerating additionally, makes wind pushing temperature be lower than room temperature.
By Figure 13-14 as can be known, evaporation tank 4 and 5 inwalls post absorbent gauze 41, are provided with evaporation tank 29 in the case, and evaporation jig 39 is provided with absorbent gauze 40, thereby evaporation area increases about 0.6 times.As calculated, the total evaporation area is about 2.4 square metres.According to Wuhan City's central meteorological observatory data, 92 year summer, free surface of water was 12.4mm at the highest daily evaporation amount, then hour steam output is 12.4/24=0.517mm, under the equality of temperature condition, decompression evaporation is not subjected to outside relative moisture and Influences on Wind Velocity, its evaporation rate is generally than very fast, and is also more stable, now gets
Hour steam output: 0.517mm
Latent heat of vaporization value: 574 kilocalories/kilogram
The refrigeration work consumption that can calculate this air-cooling fan is as follows:
N=2.4m
2* 0.000517m * 1000kg/m
3632 kilocalories * 736 watts of * 574 kilocalories/kg ÷
=829 watts
(1 horsepower/hour=632.5 kilocalories, 1 horsepower=736 watts)
By Fig. 1-16 as can be known, air-cooling fan of the present invention is not provided with compressor, freon also useless, only by a motor 1 of making air-supply usefulness and ten to external sealed and the evaporation tank 4 and 5 that interconnects, and endothermic plate 6 at the bottom of the case.Its refrigeration is to obtain by the existing potential energy source of development and use.
As seen, notable feature of the present invention is to make flabellum 15E-E section to be airfoil, and when having developed the impeller high speed rotating, the top circumferentially adds flabellum behind axially because the negative pressure that the air intake acceleration occurs simultaneously on the flabellum 15E-E section, be subjected to the comprehensive effect of these three aspects of centrifugal action with gas molecules in the hollow flat tube 16, make air outlet 55 by hollow flat tube 16 ring cavities 22, air outlet 21, hollow garden pipe 9, intakeport 27 grades realize the decompression evaporation in evaporation tank 4 and 5, absorption refrigeration and form gas-entered passageways by endothermic plate 6 is realized the heat exchange to air intake.Its feature be on the other hand, by the multi-deck combined structure of evaporation tank 4 and 5, realize the large-area sweat cooling of overlapping type, the sufficient heat exchange of long flow process, thereby reach the effect that electric fan can send cold wind.
In this air-cooling fan when air-supply refrigeration,, the vapour molecule of running out of from evaporation tank 4 and 5 is arranged in the airy room, the short time will delivery chamber outside.According to Wuhan City's central meteorological observatory data, the stove Chengwu Chinese, in the summer high temperature time, relative moisture is 35%, and the room that the people lives, relative moisture is suitable with 60-70%, so to air ventilation and dry room, it is useful heating in right amount.And because this air-cooling fan wind pushing temperature is lower than room temperature, humidity is suitable, so make the people produce nice and cool sense with fresh air.
From Fig. 3,13,14, as can be known, be equipped with water outlet tubule 42 under each evaporation tank, and it is continuous with lucite pipe 43 sealings, 43 times head-clamps of plastic tube extremely seal, water liquid height can be obvious at a glance from plastic tube in the evaporation tank 4 and 5, if do not need refrigeration, 43 times end closures of plastic tube are opened tapping to empty, then can implement general air-supply.Top layer evaporation tank cover plate 38 is provided with water filling hole 13 and joins spiral cover, takes off spiral cover when evaporation tank 5 water fillings, and from top to bottom, water is automatic overflow completely then, until 44 water outlets of bottom evaporation tank water nozzle, promptly shows and all fills with.
Brandreth shown in Figure 10-12 45 is evaporation tank 4 and 5 and the positioning supporting frame of supporting plate 49, and its two ends up and down are fixed on the body, and brandreth 45 first are angle steel, brandreth 45 second are provided with the hinge 50 of living, pass hole 48 with nut 46 combinations with screw rod, can make evaporation tank 4 and 5 be easy to mounting or dismounting, firm position.When each evaporation tank fall successively from bottom to up the position fixing after, evaporation tank 4 and 5 upper-lower seal short tube 32 and 33 cooperate by male and female and connect, and establish rubber ring 34 on the mating face, at the external rubber case 31 of pipe, can satisfy the requirement of airtight of water tightness, it is to connect the passage that each layer evaporation tank implemented moisturizing, also is to connect each layer evaporation tank suction vapour molecule, implements the passage of many compartments of large size decompression evaporation.
From Fig. 1 and 16 as can be known, this air-cooling fan when air-supply, by speed control switch 56 can realize manual pass, stop with one, two, the third gear rotating speed, when speed regulator work, signaling lamp 57 demonstrations are arranged.
The transmission shaft 3 of this air-cooling fan can be made by ferro-alloy and add the chromium plating processing, also can make by nichrome, evaporation tank 4 and 5 can be by the good aluminum alloy of heat conduction, nickel alloy or ferro-alloy are made, body 25 and member 8,11,13,26,45, can make by ferro-alloy Deng all, fan 15,19,20 can be made by intensity high ferro-alloy or engineering plastics, stuffing box packing is an Expanded graphite, air regulating board plate 17, balancing pole 18, support seat board 58, blinds air intake window 24, air conducting cover 14, water spilage tray 51, machine cap 12, back wicket 30 grades all can be made by engineering plastics, and air filter 23 can be made by foamed plastics.
From the above mentioned, this air-cooling fan outside humidification function and the general forced ventilation function, also has fragrant function except possessing refrigerating function as can be known, only needs to inject in evaporation tank 5 perfume of a small amount of own satisfaction, and fragrance will prolongedly be covered with the room equably.It can develop potential and reach 700-800 watt in when work, and the wind that its is discharged has the nice and cool sense behind the shower in summer.
