Abstract

The utility model provides an inclined-bellows evaporating air cooler. The air cooler comprises an evaporating tube bundle, a fan, a mist catcher, a water spray tube, a spray nozzle, a circulating water pump and a water box, wherein the fan is arranged at the top of the air cooler; the mist catcher is arranged between the fan and the water spray tube; the evaporating tube bundle is arranged below the water spray tube; the water box is arranged below the evaporating tube bundle; heat exchange tubes of the evaporating tube bundle adopt bellows; the bellows are put downwards in an inclined manner in the flow media direction in the bellows; and a processing tube bundle provided with finned tubes can be arranged between the fan and the water spray tube. Processing media flow in the evaporating tube bundle, spray water flows downwards outside the bellows of the evaporating tube bundle, and meanwhile, air flows from bottom to top outside the bellows, so that heat inside the bellows are transferred to the air and exhausted into the air with the help of water outside the bellows; as the bellows are adopted, the media in the bellows form turbulent flow, so that the heat exchange effect is better; and meanwhile, the bellows are put downwards in an inclined manner in the flow media direction in the bellows, so that the flowability of the media in the bellows is better.

Description

Tilting bellows evaporation air cooler

Technical field

The utility model relates to a kind of industries such as oil, chemical industry, metallurgy, electric power that are applied to, and finishes the equipment of thermal medium condensation or cooling, a kind of specifically tilting bellows evaporation air cooler.

Background technology

At present, because the protection water resource adopts air to cool off the application that obtains more and more widely, known air cooler mainly is dried air cooling pattern, mainly leans on the augmentation of heat transfer cooling medium of finned tube.But require low situation for outlet temperature, dried air cooling is difficult to meet the demands.A kind of in recent years evaporative air-cooling is widely used, and it is by the principle of from top to bottom circulated sprinkling water and the evaporation latent heat outside the air of going up is down taken away pipe, and processing medium can be cooled near environment wet-bulb temperature, good cooling results, and floor space is little.The surface evaporation air cooler of patent 96200559.2 adopts be a kind of pipe as heat exchange element, what patent 01211774.9 adopted is that elliptical tube is as heat exchange element.

The utility model content

Technical problem to be solved in the utility model is: be to provide a kind of structure simpler, heat transfer efficiency is higher, and the unit heat exchange area is big, floor space evaporating air cooler still less.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of tilting bellows evaporating air cooler is provided, form by the tube bank of evaporation light pipe, blower fan, mist eliminator, sparge pipe, nozzle, water circulating pump, water tank, blower fan is located at the top, mist eliminator is in the middle of blower fan and sparge pipe, the tube bank of evaporation light pipe is below sparge pipe, and water tank is established in evaporation light pipe tube bank below.The heat exchanger tube of evaporation light pipe tube bank adopts bellows, and bellows is directed downwards to tilt to put along flow media in the pipe.The technology tube bank of band finned tube can be set between blower fan and sparge pipe.

Operation principle of the present utility model is: processing medium flows in the tube bank of evaporation light pipe, and shower water flows downward outside evaporation light pipe tube bank pipe, and air flows outside pipe from bottom to top simultaneously, the heat that pipe is inboard, by means of the water in the pipe outside, pass to air, and be discharged in the air.Since adopted bellows, medium formation turbulent flow in the pipe, heat-transfer effect is better, and simultaneously, bellows is directed downwards to tilt to put along flow media in the pipe, makes the interior air flowability of pipe better.

Fig. 2 is the schematic diagram of the tilting bellows evaporation air cooler of the utility model bellows cross section;

Specific embodiments

Tilting bellows evaporation air cooler mainly is made up of evaporation light pipe tube bank 3, blower fan 11, mist eliminator 2, water injector 10, water tank 5, finned tube tube bank 1 in the accompanying drawing 1, the heat exchanger tube 4 that wherein evaporates light pipe tube bank 3 is bellows, and bellows is directed downwards to tilt to put along flow media in the pipe.Given bellows cross-sectional view in the accompanying drawing 2, it is made of crest and trough.The utility model is compared with known common evaporating air cooler, adopted tilting bellows as heat-exchange tube, the outer shower water of its pipe is dirty along bellows, pass to air again, can take away more latent heat, pipe is interior owing to its interior film heat transfer coefficient after adopting bellows is higher, so, the utility model better effects if.

The utility model is simple, and is advanced, reliable, can adopt carbon steel, low-alloy steel, stainless steel and dual phase steel manufacturing, can be applied to fields such as oil, chemical industry.

Claims

1. tilting bellows evaporation air cooler is made up of evaporation light pipe tube bank, blower fan, mist eliminator, sparge pipe, nozzle, water circulating pump, water tank, and it is characterized in that evaporating the heat exchanger tube that light pipe restrains is bellows (4).
