The utility model discloses using finned tube evaporation heat transfer, having improved heat exchange efficiency greatly, the refrigerant earlier through the heat exchange tube precooling, got into the easy scale deposit point that water had been avoided to the interior refrigerant of finned tube before the entering finned tube, and the finned tube is difficult for scale deposit, long service life.
Description
Technical field
The utility model relates to a kind of cooling device, specifically, relates to a kind of evaporative condenser.
Background technology
Evaporative condenser utilizes the shower water outside heat exchange coil to evaporate, and takes away the heat of high temperature liquid refrigerant in coil pipe, thus make the cold-producing medium in pipe again be converted to liquid a kind of equipment by gaseous state.
At present, traditional evaporative condenser also exists cooling capacity deficiency, susceptible to plugging problem.Finned tube is a kind of efficient heat-exchanging pipe, but due to the fin on its surface, when being applied to evaporation and heat-exchange, there is easy fouling, life-span low defect.
Utility model content
The purpose of this utility model is the weak point overcoming above-mentioned conventional art, provides a kind of cooling effect strong, less scaling, not susceptible to plugging evaporative condenser.
The technical solution of the utility model is:
A kind of evaporative condenser, it is characterized in that: comprise superposed axial flow blower and be positioned at water tank and the air intake grid of bottom, water collection device is provided with below axial flow blower, the first heat exchanger components and the second heat exchanger components is provided with below water collection device, first heat exchanger components is positioned at above the second heat exchanger components, first heat exchanger components is communicated with the second heat exchanger components, spray equipment is respectively equipped with above first heat exchanger components and the second heat exchanger components, spray equipment is communicated with water tank by water circulating pump, and the second heat exchanger components comprises several finned tubes.
A kind of concrete prioritization scheme, the first heat exchanger components is heat exchanger tube.
A kind of concrete prioritization scheme, finned tube comprises outer support pipe and inner support tube, is provided with helical fin between outer support pipe and inner support tube.Helical fin is used to have cooling agent flow clear and coherent smooth, not susceptible to plugging advantage.
A kind of concrete prioritization scheme, the quantity of water circulating pump is two, and one of them water circulating pump provides cycling use of water for the spray equipment above the first heat exchanger components, and another water circulating pump provides cycling use of water for the spray equipment above the second heat exchanger components.
The utility model uses finned tube evaporation and heat-exchange, and substantially increase heat exchange efficiency, cold-producing medium is first by heat exchanger tube precooling before entering finned tube, and the cold-producing medium entered in finned tube avoids the easy fouling point of water, and finned tube is less scaling, long service life.
