Description
Technical field
The present invention relates to heat-exchange apparatus field more particularly to a kind of natural cooling source units with evaporative condenser.
Background technique
The natural cooling source unit with evaporative condenser on current market, evaporative condenser generally use coil pipe
Formula set of heat exchange tubes is cooled down in heat exchanger outer surface with shower water at heat exchanger, and is taken away using the evaporation of the shower water of circulation
Heat.However, this coil exchanger heat exchange pipe external surface is generally smooth surface, heat exchange efficiency is low, meanwhile, cooling water steams
Hair heat exchange surface area is small, and the spacing of coil pipe need to widen to increase the heat-exchange time of cooling water and air, to make entire heat exchanger
It is bulky.Moreover, because being flowed between the upper down tube of coil pipe without medium guide cooling water, when cooling water lands from top to bottom
When, under the traction of vertical wind direction, unordered wave of cooling water is also easy to produce winged water, and water distribution is uneven on coil pipe, easily deposits and does, and reduces
Exchange capability of heat and there are fouling risks.
The first Chinese patent CN 204787929U of applicant discloses a kind of compound evaporative condenser of plate pipe,
Heat exchanger components are mainly heat exchanger fin；The heat exchanger fin includes sheet body and heat exchanger tube of the sheet body wherein in one side is arranged in, and is led to
Crossing thermoconductive adhesive layer comes into full contact with sheet body with the heat exchanger tube, and heat exchanger tube is enabled to generate rib effect by sheet body, increases
Effective heat exchange area, while piece physical efficiency drainage cooling water forms continuous flow plane, solves the problems, such as the unordered winged water of cooling water,
But be provided only on due to the heat exchange coil of the heat exchanger fin in the one side of the sheet body, cause sheet body one side because heat exchange coil with
Cooling water direct contact heat-exchanging and water temperature is higher, another side is due to being spaced sheet body and making indirect heat exchange between cooling water and heat exchange coil
Water temperature is relatively low, causes the cooling capacity of the cooling water on sheet body two sides to be not efficiently used, heat exchange efficiency is relatively low.Meanwhile for diameter
Biggish heat exchange coil, bending radius is larger to be caused tube spacing excessive and keeps piece bulk area excessive.
In addition, only one heat exchange coil of such heat exchanger fin, can only recycle a kind of fluid working substance, cause to have used described cold
The existing natural cooling source unit of condenser can only run heat pipe circulation in winter or pass through recycling in summer operation compressor refrigeration
The cooling water cooling capacity of evaporative condenser come realize natural cooling source run, operational efficiency is low, at high cost.
