Description

Air conditioning type electric fan

The utility model is a kind of air-conditioning-type electric fan, belongs to the household electrical appliance class.

Existing air-conditioner generally all adopts cold-producing medium and compressor etc., can change environment temperature effectively after work, but its power consumption is big, price is expensive; Though and existing electric fan price is low, power consumption is less, can not change environment temperature effectively, and in the summer of sweltering heat, the work of electric fan can only cause indoor air to flow, and can not give people's feel cool.

The purpose of this utility model is the deficiency that overcomes above-mentioned two kinds of household electrical appliance, and a kind of air-conditioning-type electric fan is provided, and compares with electric fan with existing air-conditioner, has played the effect of maximizing favourable factors and minimizing unfavourable ones.

The utility model is made up of air-conditioning box and electric fan two parts, in the air-conditioning box, adopts semiconductor cooler as Cooling and Heat Source and the efficient heat exchanger (evaporimeter and radiator) by making with hot pipe technique, the effect that reaches refrigeration and heat.

Be further described below in conjunction with 1 pair of architectural feature of the present utility model of Figure of description.

Air-conditioning box of the present utility model mainly is made up of casing 5, insulation chambers 4, semiconductor cooler 8, radiator 7 and evaporimeter 9.

Casing 5 fuses for overall plastic square cylinder and with insulation chambers 4, for integrated poured.The heat radiation wind deflector 6 that blows open with the wind and close automatically is equipped with at casing 5 tops; The panel 1 of casing 5 is curved and have and be with bell-mouthed horizontal oblong aperture, and covering has graticule mesh 2 and horizontal wind-guiding curtain sheet 3, and wind-guiding curtain sheet is orientable or swing back and forth automatically.

Insulation chambers 4 is two concentric garden tubes, and the filled with polyurethane foam foamed thermal insulating is as heat-insulation layer therebetween.Evaporimeter 9 is housed in insulation chambers 4.

Semiconductor cooler 8 is to vary in size according to fan to select different power as Cooling and Heat Source.Semiconductor cooler feeds direct current, and the cold and hot surface of semiconductor cooler also changed thereupon when current polarity changed.The voltage of semiconductor cooler is got by the 220V AC rectification or directly is connected to dc source, and the big I of voltage changes or directly voltage swing manufacturing on demand by the series-parallel system of semiconductor cooler.Semiconductor cooler 8 is loaded on the heat-insulation layer of insulation chambers, and huyashi-chuuka (cold chinese-style noodles) contacts with evaporimeter 9, is coated with thermal grease conduction therebetween.

Evaporimeter 9 and radiator 7 are critical components of air-conditioning box, form by heat pipe and fin, the configuration of its heat pipe and the area of dissipation of fin are all through heat and cold and cold and hot EQUILIBRIUM CALCULATION FOR PROCESS and obtain, the connected mode of fin and heat pipe has multiple, closely is enclosed within on the heat pipe, at this after being generally the fin punching, if fin copper sheet, heat pipe copper tube manufacturing contacts better for making fin with heat pipe, can adopt whole wicking; Adopt copper, aluminum or aluminum alloy manufacturing can directly roll out fin thereon if another kind method is a heat pipe, so just do not have fin and heat pipe loose contact problem.Form very little gap between the fin, when making air flow through the gap and cold or heat are taken away.Hot pipe technique has been adopted in the conduction of the cold-peace heat of evaporimeter 9 and radiator 7, heat pipe is made up of shell (can make different shape), capillary structure and liquid refrigerant, the liquid refrigerant that capillary structure promptly is housed in the vacuum chamber of evaporimeter 9 and radiator 7 and mixes with it, reach quick transmission heat and cold by covert process, show excellent transmission heat and the effect of cold and good isothermal vertically.Evaporimeter 9 is loaded in the insulation chambers 4; Radiator 7 is loaded between insulation chambers 4 tops and casing 5 tops, is discharged by the top in order to heat.Between insulation chambers 4 and casing 5, heat protective device is housed also, burns out because of overheated to prevent semiconductor cooling device.

Electric fan is similar to the common electrical fan basically, is made up of fan blade 10, guard 12, motor 11 and base 14 etc., and power supply is housed in the base, and the seesaw mechanism 13 that key and adjusting tank inclination angle are pressed in operation is housed on the seating plane.

The course of work of the present utility model is such: when needs cold wind, press down cold wind and press key, the semiconductor cooler energising produces the cold and hot surface of 55 ℃ of temperature difference, be transmitted to respectively on evaporimeter 9 and the radiator 7, fan blowing simultaneously, the air of certain speed flow to into the fin slit of also passing through evaporimeter in the insulation chambers 4, fully contact with the fin huyashi-chuuka (cold chinese-style noodles), the air stream that enters has reduced temperature, blows out cold wind.Simultaneously; the semiconductor cooler hot side is blown out heat through the air-conditioning box top by radiator 7; because the effect of heat radiation wind deflector 6; the direction that hot blast blows out is the deflection back upper place; avoid cold and hot general mood stream to mix; radiator temperature and evaporator temperature all pass through cold and hot EQUILIBRIUM CALCULATION FOR PROCESS; guarantee that the semiconductor cooler hot-face temperature is no more than 75 ℃; the unlikely semiconductor cooler that burns out; further safeguard measure is carried out by heat protection, considers the contact temperature difference of semiconductor cooler hot side, and the design temperature of heat protection is 70 ℃; surpass this i.e. action of temperature heat protection, make the semiconductor cooler outage.

The air-conditioning-type electric fan has guaranteed that structurally cold wind, hot blast and the air intake of outlet all have certain direction, avoid mutual mixing, consider when designing simultaneously that cold wind outlet wind speed reaches 1 meter per second, blow to when leaving 1 meter to 1.5 meters far away human body to be about 0.5 meter per second, and make the people feel the gentle breeze of feeling nice and cool.When environment temperature was 35 ℃, outlet cold wind can reach 25 ℃, and about about 350 watts of consumed power, also available in addition change semiconductor cooler electric current reach and make refrigerating capacity or the continuously adjustable purpose of heat, to obtain the cool breeze and the warm braw of different temperatures.

When the needs warm braw, press down the warm braw snapper, and changed the semiconductor cooler current polarity its cold and hot surface is exchanged, the effect that is evaporimeter and radiator is exchanged, therefore the utility model not only is used for the wind that blows on summer, also can be used to heating winter, other any warmer thermal efficiency of its thermal efficiency ratio wants high when being used for warming oneself." air-conditioning-type " promptly comes therefrom.

The utility model is the same with the common electrical fan, can be made into desk-top, hanging and wall-hanging etc., also can be made into various illumination type electric fans and forms complete series.

Embodiment of the present utility model:

This example adopts 12 cun speed governing electric fans, and semiconductor cooler adopts 400W, and the insulation chambers internal diameter is 18cm, and insulation layer thickness is 3cm, and evaporimeter bulk is 12cm * 12cm * 10cm, and the outlet wind speed is 1M/ second, can make about 10 ℃ of 35 ℃ of air stream coolings as calculated.
