Description

Technical Field

[0001] The utility model relates to the technical field of thermal equipment, in particular to a heat-insulating and antifreeze type evaporative cooler. Background Art

[0002] Evaporative cooler (condenser) is a device that uses the principle of evaporative heat exchange to cool and condense materials in the tube. Its heat exchange mechanism is: the heat of the material in the tube is transferred to the spray water outside the tube through the tube wall. The spray water forms a uniform water film on the heat exchange tube and evaporates to absorb heat. The dry cold air exchanges heat with the spray water under the forced action of the fan, takes away the evaporation heat and discharges it into the atmosphere to meet the temperature drop requirements of the process system. Evaporative coolers are suitable for cooling and condensing various process materials. At present, they are mainly used in industrial refrigeration, air conditioning and refrigeration, food, chemical, petrochemical, electric power, new energy and other industries.

[0003] Evaporative coolers have high heat exchange efficiency, small footprint, and low operating energy consumption. They are mainly used in two structures: cross-flow and counter-flow. Counter-flow evaporative coolers are evaporative coolers that only use the latent heat of water for heat exchange. The air inlet is a counter-flow air inlet at the bottom, which alternates with the spray water at the bottom to form saturated hot and humid air, and the heat is discharged from the top fan. Cross-flow evaporative coolers use the sensible heat (latent heat) heat exchange of the coil section + the latent heat exchange of the filler section to remove heat. The coil section mainly relies on the spray water temperature rise or evaporation to remove heat, and the heat of the spray water heat exchange temperature rise is removed by the filler evaporation heat exchange.

[0004] The outer guard plate structure of conventional evaporative coolers has the following disadvantages:

[0005] Disadvantage 1: There is 40-50mm of empty space on the outside of the existing evaporative cooler box panel, which is not fully utilized.

[0006] Disadvantage 2: The heat exchange coil area is inside the box plate of the evaporative cooler that is in direct contact with the outside world. During the year-round operation, due to the large range of ambient temperature changes (-30℃~40℃), and the box plate is made of metal with good thermal conductivity, the temperature of the outer shell plate can reach above 50℃ under the sun in summer. The box plate transfers heat to the spray water and air, resulting in ineffective heat exchange. In winter, the box plate is in a low temperature state, and the heat of the medium in the coil is transferred to the outside air through the box, which reduces the temperature of the material in the heat exchange coil. When the medium in the tube is circulating water, there will be a hidden danger of freezing. In addition, the box plate is affected by external environmental factors such as wind, snow, and corrosion for many years, and the box corrodes quickly, reducing its service life.
