Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a novel evaporative condenser with a bottom box body and a two-layer structure. Background Art

[0002] An evaporative condenser is a heat exchange device, also known as an evaporative cooler (condenser). It uses the evaporation of some of the spray water outside the coil to absorb the heat from the high-temperature gaseous refrigerant inside the coil, gradually cooling the refrigerant from a gaseous state to a liquid state. The evaporative condenser's operating principle is to use the evaporation of some of the water to absorb the heat released by the gaseous refrigerant during the condensation process. The high-temperature gaseous refrigerant enters from the top of the coil, exchanges heat with the spray water and air outside the coil, and gradually condenses from a gaseous state to a liquid state, flowing out of the lower outlet. Cooling water is pumped to the spray system above the condensing coil by a water pump, evenly spraying the outer surface of the coil to form a water film. After the spray water and air absorb heat, some of the water evaporates, and the remaining water falls back into the sump for recycling. Water droplets in the air are trapped by a dehydrator and fall back into the sump.

[0003] Currently, existing evaporative condensers basically have a fan installed at the top, an air inlet structure installed above the water collection tray frame, and a single-layer frame module with a built-in condenser tube installed above the frame structure where the air inlet structure is located. Since the condenser tube structure that receives the evaporation of cooling water is set as a single layer, it is not conducive to improving the cooling water spraying efficiency and the air duct circulation range. The lack of a two-layer or multi-layer design makes it difficult to improve the evaporation efficiency. Utility Model Content
