Abstract

The utility model discloses a novel air-conditioning fan, which consists of a machine body (2), a fan (6) (8), a heat-exchanger (13), an air filter (18) and a wind-adjusting door (1). The utility model is characterized in that: an array of flat tubes (21) are arranged on an upper and a below tube plates (23) of a rectangular heat exchanger (13) in equivalent height and distance. Two tube mouths of the flat tubes (21) are communicated with the upper and the below tube plates (23), and are fixedly connected with a water seal; the flat tubes (21) are covered with water-absorbing gauze (22), and is also vertical down to a faceplate of the tube plates (23); when the water liquid is ejected into the heat exchanger (13), the water-absorbing gauze (22) is filled with the water; the fan (6) (8) will be started up to make the air flow of a tube distance and a shell distance inside the heat exchanger (13); and then the large humidity in the shell distance is inducted out from the outdoor; because of the phase-change heat-absorbing function to the water molecule on the water-absorbing gauze (22), the temperature of the flat tube will decrease quickly to keep in the local humidity and temperature; so the heat air inside the room flows to the flat tube (21) continually to be cooled by contacting with the cool inner wall; so the cool wind with the temperature of 2-6 DEG C lower than that in the indoor can be obtained. The utility model can realize the actual, reliable and comfortable air-condition effect without needing compressor or any other ice and so on.

Description

The air-conditioning fan

The utility model relates to air-conditioning technique, specifically is a kind of air-conditioning fan.

At present, its performance indications of the air cooler on the market are: back on the rocks leaving air temp is lower than room temperature 2-6 ℃; Not on the rocks, do not have the cold wind effect through using proof.Yet the cold wind index is the critical index of this product, and other conformability index such as electronic control technology are very strong even this index is very weak, and eventually because of not satisfying the needs of consumer to cold wind, what only can suffer consumer's mercilessness negates.In addition, this product is when the refrigeration air-supply, the vaporize water of decalescence is arranged in indoor in company with " cold wind ", increase a humidity for indoor air, according to correlation theory and experience, the room air water capacity is originally higher should the situation of dehumidification under, especially in the Yangtze river basin and the areas to the south, the result of humidification only can increase feeling of oppression and heat.But the humidification of this product is interdependence with sending cool breeze, wants to cancel humidification, equals to have cancelled this product itself.Obviously, this product is because of existing major defect, so need be sought technical support on refrigeration mechanism, in the hope of the correct road that effects a permanent cure on the refrigeration mechanism.

The purpose of this utility model provides a kind ofly without compressor and fluorine, does not also need by ice cube to show the cold wind effect, but rely on structural doing in the proper way, promptly obtain reliable and stable cold wind effect, and can arrange the phase transformation vaporize water in the open air, thereby can be used for the air-conditioning fan of enclosed cooling.

The utility model is achieved in that makes flat tube with the pipe of shell-and-tube heat exchanger, the flat tube wall completely wraps the gauze that one deck corrosion resistant is fungi-proofing and water absorption rate is high outward, be arranged in parallel at a certain distance between flat tube and the flat tube, and flat tube is vertical with last lower perforated plate, its pore penetrates two tube sheets up and down, and it is affixed with two tube sheet watertights, flat tube embeds rear wall plate, and and draw back certain distance between the wallboard of the place ahead, above the rear wall plate right-hand part with respect to each flat tube between the position establish the shell side air inlet, below the rear wall plate left side relatively between each flat tube the position then establish the shell side air outlet.Like this, in housing, inject water liquid, the outer gauze of pipe has been filled moisture content, make tube side and shell side air occur flows thereupon, and make the turnover wind of shell side lead to the open air, and the air intake of tube side and air-out are indoors circulated, then on business know the wet and dry bulb temperature difference data, can obtain low cold wind, make the indoor stable comfortable air-conditioning effect that does not need additional conditions that reaches.

Below, be further described with accompanying drawing in conjunction with the embodiments:
