Sealing mechanism of air cooler

Technical Field

The utility model belongs to the technical field of the air cooler sealing technique and specifically relates to a sealing mechanism of air cooler is related to.

Background

Air coolers, referred to as air coolers, use air as a coolant, either as a cooler or as a condenser. The air cooler mainly comprises a tube bundle, a bracket and a fan. The air cooler hot fluid flows inside the tubes and the air is blown outside the tube bundle. Because the ventilation volume required by heat exchange is very large and the wind pressure is not high, an axial flow fan (see a fluid conveying machine) is mostly adopted. The type and material of the tube bundle greatly affect the performance of the air cooler. Because the air side has a low heat transfer coefficient, fins are often added to the tubes to increase heat transfer area and fluid turbulence and reduce thermal resistance. The air cooler mostly adopts radial fins.

The plurality of tube bundles are connected through fins to form a heat dissipation plate, and the periphery of the heat dissipation plate is connected with a water outlet pipeline for collecting condensed water and an air inlet pipeline for providing hot steam for the heat dissipation plate. For the radiating rate who improves air cooler, connect the use with the polylith heating panel usually, the polylith heating panel splices through the simple mode of placing of pipeline. The connection mode can cause a large gap to exist between the pipelines, and the airflow directly flows through the gap between the pipelines and cannot flow through the gap between the fins, so that the condensation efficiency of the air cooler is low.
