Abstract
The utility model relates to refrigeration equipment, in particular to an evaporative condenser. The counterflow evaporative condenser comprises condensing coil pipes, a spraying device, a heat exchange layer, a water barrier, a water collecting tank, a circulating pump and a fan and is characterized in that the spraying device is provided with a five-petal shape nozzle or has a structure that a water outlet is arranged at the lower end of a water spraying pipe and the bottom surface of a nozzle has no hole and the upper surface thereof is provided with a nozzle head with a concave groove. The condensing coil pipe is internally provided with wave-shaped internal plug-in components; the cross section of the condensing coil pipe is an oblate closed snake-shaped coil pipe resembling to an ellipse and inclines 10-15 degrees towards the condensing agent flow direction. The heat exchange layer is profiled by a V-shaped concave groove with PVC materials. Compared with condensers with equal heat exchange area and pipe speed, the utility model can increase 40 percent of heat exchange efficiency and save water and electricity.
Description
(1) technical field:
The utility model relates to refrigeration plant, especially evaporative condenser.
(2) background technology:
Existing evaporative condenser, containing condenser coil, liquid distribution, middle part has heat exchange layers, bottom to have water leg, outside to be provided with circulating pump and blower fan.During evaporation work, cooling water in the water leg is delivered to liquid distribution by water pump, spray is on the condenser coil surface, spray is at the cooling water on condenser coil surface, behind the heat of absorption refrigeration agent, temperature raises, and a part flashes to water vapour and vapors away, and all the other condensations after drop in the water leg after the heat exchange layers cooling recycle.From the above, the factor that influences the condenser exchange capability of heat mainly is heat exchange area, heat exchanging fluid---the mixability of empty G﹠W, recirculated water utilization rate etc.
(3) goal of the invention:
The purpose of this utility model provides a kind of raising heat exchanger effectiveness, refrigeration good and the water saving reverse-flow evaporative condenser.
The technical solution of the utility model is: reverse-flow evaporative condenser, comprise condenser coil, liquid distribution, heat exchange layers, water fender, water leg, water circulating pump, blower fan, it is characterized in that: it is that apopore is arranged on the sparge pipe lower end that liquid distribution adopts five lobe shape nozzles or structure, the nozzle bottom surface atresia, above have the shower nozzle of groove.
The waveform interpolation part is arranged in the described condenser coil, and tube section is similar oval-shaped oblate closed serpentine coil, along the condensing agent flow direction, tilts 10 °～15 °.
Heat exchange layers is that the pressing of PVC material V-type groove forms.
The utility model has the advantages that: water is under the effect of pump, pump is in shower, shower nozzle through particular design, evenly effectively be distributed in the condenser coil outer surface, under the effect of blower fan wind-force, encase coil pipe cleverly, form film, make the interior high temperature refrigerant of water, air and pipe carry out heat exchange effectively fully.Shower nozzle is through overtesting, corrosion-resistant, anti-dismounting, anti-flushing, and water spray best results, and can prevent the fouling of condenser coil outer surface.The waveform interpolation part is housed in the condenser coil, increases flow process, cross sectional shape is special oblateness, has increased heat transfer area, thereby guarantees heat-transfer effect more fully.Condenser coil designs with 10 °～15 ° angles of inclination in addition, guarantees the smooth and easy outflow of condensate liquid.PVC heat exchange layers V-type groove makes heat exchange area increase, and every pressing forms, and connects closely, can better water cooling be got back to water leg and utilize, thereby save electric energy.In order to guarantee that air quantity do not take away moisture, adopt PVC material specialized designs water fender, guarantee that maximum moisture content contact with air and the less air pressure drop.Water fender effectively prevents water from running off after air-flow direction is changed through three times, and water flows into water leg and recycles, and reaches the water saving purpose, more is applicable to water resource poor area use.Compare with the fast condenser of pipe with equal heat exchange area through experiment, the utility model can improve heat exchange efficiency 40%.
