Description

Portable air cooler

Technical Field

The utility model belongs to the technical field of the air cooler, concretely relates to portable air cooler.

Background

Air coolers, air coolers for short, use air as a coolant, either as a cooler or 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 required for heat exchange is large and the wind pressure is not high, axial flow fans (see fluid conveying machinery) are 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. Light pipes with an outer diameter of 25mm, low-finned tubes with fins of 12.5mm in height and high-finned tubes with fins of 16mm in height are generally used in air coolers. The fins are typically made of a material with high thermal conductivity (most commonly aluminum) and are wrapped or embedded onto the light pipe. In order to strengthen the heat transfer effect of the air cooler, water can be sprayed in the inlet air for humidification. This both reduces the air temperature and increases the heat transfer coefficient. The adoption of the air cooler can save industrial water in the large and middle schools and reduce environmental pollution; the capital cost is reduced. Especially in water-deficient areas, the contradiction of insufficient water source can be alleviated by replacing water cooling with air cooling; present air cooler is likely to damage the back ventilation blower and need overhaul after long-time the use, but ventilation blower on present air cooler generally all is together fixed through complicated connection structure with the organism, and unable quick dismantlement gets off overhauls and changes during the maintenance, uses inconveniently, and air cooler probably leads to there being debris in the main part after placing for a long time in addition, because there is intensive tube bank in the organism, leads to the problem that needs the clearance.
