Background
The evaporative condenser is a refrigeration device commonly used in chemical enterprises. The conventional evaporative condenser sprays cooling water on the outer surface of the heat exchanger to form a thin water film. High-temperature gas enters from the upper collecting pipe of the condensing heat exchanger, and a water film on the outer surface of the condensing heat exchanger is evaporated, so that heat exchange is realized, the high-temperature gas is condensed, and condensate flows out from a liquid outlet on the lower part of the condensing heat exchanger. The cooling water which is not evaporated absorbs heat and flows into the water tank through the heat dissipation filler below. The axial flow fan is used for pumping to accelerate the evaporation of the water film on the surface of the heat exchanger and simultaneously cooling the water on the surface of the heat dissipation filler. Therefore, the heat dissipation filler is an important component of the evaporative condenser, and the performance of the heat dissipation filler directly affects the refrigeration effect of the evaporative condenser. At present, the heat dissipation filler of the evaporative condenser is usually made of PVC material and is integrally fixed on a connecting rod in series. The total size of the heat dissipation filler is large (3 meters in length, 2 meters in width and 1.5 meters in height), and the weight is heavy, so that the heat dissipation filler is often collapsed and damaged due to vibration, aging and the like in the operation process of the evaporative condenser, and once the heat dissipation filler is damaged, the heat dissipation filler needs to be integrally replaced, and the maintenance cost is high.
