Abstract
The utility model discloses a water defrosting air cooler. The air cooler comprises an evaporation chamber, wherein an evaporator coil is arranged in the evaporation chamber; a liquid inlet header is connected to the lower part of the evaporator coil; an air return header is connected to the upper part of the evaporator coil; and an axial-flow fan is arranged at the front end of the evaporation chamber. The air cooler is characterized in that a water distribution plate is arranged above the evaporator coil, a water drainage plate is arranged below the evaporator coil, and the axial-flow fan is connected with the front end of the evaporation chamber through a flow guiding fan drum. As a preferred scheme, the outline part of the flow guiding fan drum, connected with the front end of the evaporation chamber, is trumpet-shaped, the outline part of the flow guiding fan drum, connected with the axial-flow fan, is cylindrical, and further, the flow guiding fan drum 4 is a carbon steel flow guiding fan drum. The water defrosting air cooler has the advantages of simple structure, low noise, high efficiency and rapidness in defrosting.
Description
Technical field
The utility model relates to aerial cooler, refers to it is a kind of water defrosting aerial cooler particularly.
Background technology
The pattern of aerial cooler has a variety of, because of difference differences such as purposes, working medium.Aerial cooler commonly used at present is similar with aerial cooler basic structure with the ammonia of freezer, all is made up of vaporization chamber, evaporation coil and fin, axial flow blower etc.During refrigeration, cold-producing medium gets into evaporation coil from the feed liquor collector, through evaporating after the air heat exchange of passing through with the coil pipe external forced, becomes gas and gets into the compressor air suction pipeline from the return-air collector.Because of frosting occurring in the heat transfer process, so aerial cooler must be provided with the defrosting system.Common water defrosting system is provided with spray header on vaporization chamber top, is furnished with a lot of apertures on the water pipe, and defrosting water sprays on fin and coil pipe through the aperture on the water pipe after getting into water pipe, flows into drain pan after the defrosting and leads away.This kind structure has the uneven shortcoming of defrosting, exists the position, dead angle can not defrosting, influences the heat exchange effect.And the defrosting time is long, and is bigger to the influence of storehouse temperature.
Summary of the invention
The purpose of the utility model will provide a kind of simple in structure, low noise, high efficiency, defrosting water defrosting aerial cooler rapidly exactly.
For realizing above-mentioned purpose; The water defrosting aerial cooler that the utility model designed comprises vaporization chamber, is provided with evaporation coil in the said vaporization chamber; Said evaporation coil bottom is connected with the feed liquor collector; Said evaporation coil top is connected with the return-air collector, and the front end of said vaporization chamber is provided with axial flow blower, and its special character is: the top of said evaporation coil is provided with water distributing tray; The below of said evaporation coil is provided with drain pan, and said axial flow blower links to each other with the front end of vaporization chamber through the water conservancy diversion air duct.
As preferred version, said water conservancy diversion air duct is trumpet type with the outline portion that the vaporization chamber front end links to each other, and the outline portion that said water conservancy diversion air duct links to each other with axial flow blower is cylinder type.
Further, said water conservancy diversion air duct 4 is a carbon steel water conservancy diversion air duct.
When the utility model used, defrosting water got into water distributing tray, from the spray apertures of water distributing tray bottom, flowed down, and with the frost melts on the evaporation coil, led away behind the inflow drain pan 7.
The advantage of the utility model is: the water conservancy diversion air duct that is designed adopts carbon steel material to process the horn-like targeting port structure of tubular, and its intensity is high, and is not yielding; Can effectively avoid bumping with the blade wiping of axial flow blower; Reduce fan noise, improve fan delivery and range, and then improve refrigeration.And the monoblock type water distributing tray bottom of design above evaporation coil is evenly equipped with spray apertures, can guarantee that defrosting water evenly sprays on evaporation coil, do not have the position, dead angle, and defrosting is effective, and defrosting is rapid.
Description of drawings
Fig. 1 is the structural representation of the water defrosting aerial cooler of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail.
Water defrosting aerial cooler shown in the figure comprises vaporization chamber 3, is installed with evaporation coil 6 in the vaporization chamber 3, and evaporation coil 6 bottoms link to each other with feed liquor collector 8, and evaporation coil 6 tops link to each other with return-air collector 1.The top of evaporation coil 6 is equipped with the water distributing tray 2 of band spray apertures, and the below correspondence of evaporation coil 6 is equipped with drain pan 7.The front end of vaporization chamber links to each other with axial flow blower 5 through water conservancy diversion air duct 4.Water conservancy diversion air duct 4 is trumpet type with the outline portion that vaporization chamber 3 front ends link to each other, and water conservancy diversion air duct 4 is cylinder type with the outline portion that axial flow blower 5 links to each other, and its global shape helps aspirating fast the extraneous air heat exchange; Water conservancy diversion air duct 4 adopts carbon steel water conservancy diversion air duct, can avoid the deficiency of the easy embrittlement deformation of fiberglass water conservancy diversion air duct, improves its working life.Vaporization chamber 3 rear ends are provided with water fender 9, spill to stop defrosting water.Be with integral fins on the evaporation coil 6,, guarantee refrigeration to improve heat exchanger effectiveness.
The course of work of the utility model is following: during refrigeration, cold-producing medium gets into evaporation coils 6 from feed liquor collector 8, through evaporating after the air heat exchange of passing through with the coil pipe external forced, becomes gas and gets into the compressor air suction pipeline from return-air collector 1.The water conservancy diversion air duct 4 of carbon steel material can effectively reduce fan noise, improves air quantity and range, improves refrigeration.During defrosting, defrosting water gets into water distributing tray 2 through water pipe, and through even the spray on evaporation coil 6 of spray apertures of water distributing tray 2, defrosting water is led away after falling into drain pan 7.Defrosting can begin next kind of refrigeration cycle after accomplishing.
