Abstract
The utility model belongs to an air conditioner device, particularly a heat exchanger of an indirect evaporation refrigeration air conditioner which can provide fresh air into rooms. An air flow channel and a liquid flow channel which are not mutually communicated are formed between aluminium foil plates, the air flow channel and the liquid flow channel are mutually overlapped and crossed, and the both side edges are mutually folded and engaged. A corrugated plate is clamped in the air flow channel, a supporter is clamped in the liquid flow channel, and the height of the air flow channel is smaller than the height of the liquid flow channel. Therefore, the utility model reduces the dimension of the air flow channel, enlarges the dimension of the liquid flow channel, enhances the turbulent flow effect of the air flow, enlarges heat exchange area, reduces the flow resistance of spraying water and enhances the cooling effect of the air flow.
Description
The utility model belongs to the apparatus of air conditioning, particularly is applicable to the heat exchanger that provides the indirect evaporation refrigerating air conditioner of wet coolings such as new wind realization to indoor.
The heat exchanger that a kind of energy-conservation sweat cooling whole fresh wind air-condition device is arranged that prior art adopts is to be carried out cross-laminatedly with identical gradient by the multilayer corrugated plate, and the mutual interlock of dual-side forms the gas channel that do not communicate with each other and the heat exchanger of fluid course.Send into water and wind to two passages respectively from different directions, water and wind cross flow one in heat exchanger, water evenly sprays the trickle face of the water stream channel of heat exchanger, forms the moisture film that one deck flows downward; By the aluminium foil plate heat is passed to the water layer that flows downward at water stream channel at the new wind that gas channel flows, new wind loses wet coolings such as heat realization self.But its heat exchange area is limited, and heat exchange efficiency is high not enough, and cooling effect is desirable not enough, and the seaming structure is unreliable, and is poorly sealed.
The purpose of this utility model is to provide a kind of heat exchanger of indirect evaporation refrigerating air conditioner, not only can utilize indirect water evaporates to absorb heat and reduce wind pushing temperature, make wet coolings such as room realization, and heat exchange area is big, improve heat exchange efficiency, strengthen cooling effect, the seaming reliable in structure of two adjacent aluminium foil plate dual-sides, sealing is tight.
The utility model is achieved in that a kind of heat exchanger of indirect evaporation refrigerating air conditioner, form overlapped intersection by constituting opposite side mutual flanging seaming in both sides between the aluminium foil plate, gas channel that does not communicate with each other and fluid course, flanging seaming structure is that the both sides opposite side of adjacent two blocks of aluminium foil plates is respectively to being bent into V font flanging between the aluminium foil plate, wherein the V font flanging opening of an aluminium foil plate both sides opposite side is positioned at the outside, the V font flanging opening of another piece aluminium foil plate both sides opposite side is positioned at the inboard, in it, outside V font flanging fastens mutually stings tight formation passage, in gas channel, fold up corrugated plating, in fluid course, folding up supporter.
During the utility model work, by air-introduced machine direct wind (hot outdoor air) is passed through gas channel from the heat exchanger sidepiece, shower water passes through the trickle face of fluid course from the top of heat exchanger, form the moisture film that one deck flows downward, by aluminum corrugated plating and aluminium foil plate heat is passed to the water layer that fluid course flows downward at the direct wind that gas channel flows, moisture evaporates from the heat-transfer surface top layer, evaporation has absorbed heat-transfer surface and the airborne heat of opposite side gas channel, directly wind loses heat, wet coolings such as realization.Give a dinner for a visitor from afar between air-introduced machine is incited somebody to action and introduce the fluid course from the heat exchanger bottom, with flow reversal, upwards flow, and contact with water and to carry out the caloic exchange, make the shower water evaporation, form the mixed flow of air-flow and liquid stream, wind direction water has been supplied with the latent heat of vaporization indirectly, self has realized humidifying cooling, drains into outdoor with giving a dinner for a visitor from afar between the temperature rising by air-introduced machine.Owing in the gas channel corrugated plating has been installed, strengthened the turbulent air flow effect, enlarged heat exchange area, increased cooling effect significantly.In fluid course, fold up supporter, reducing the resistance that shower water flows in the fluid course, increasing cooling-down effect.Flanging seaming reliable in structure between the aluminium foil plate mutually combines closely the flanging of aluminium foil plate, and good seal performance can be without filling leakproof seal glue at flanging seaming connecting portion.
