Wet-film surface air cooler of composite structure

Abstract

A wet-film surface air cooler of a composite structure comprises a plurality of fins and a plurality of heat-exchanging pipes, wherein the fins are arranged in parallel at intervals and the heat-exchanging pipes penetrate through the fins. A wet-film layer is arranged on the surfaces of the fins. At least one water absorption belt is extended outwards from the wet-film layer and is used for leading water into the wet-film layer. The wet-film surface air cooler of the composite structure is simple in structure, low in cost, free of power and high in reliability. On one hand, the heat-dissipation efficiency and the COP of condensate water or tap water applied to the surface air cooler of an air conditioner are improved, the air-discharging pressure is reduced when the air conditioner is used for cooling, the COP of a common air cooling air conditioner used for cooling is increased from 3.2 to 4.1, energy is saved by over 30%, and on the other hand, the surface air cooler of the air conditioner is prevented from being frosted in winter.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a wet film surface cooler with a composite structure. Background technique [0002] The cooling mode of existing air conditioner is divided into air-cooled and water-cooled two kinds. [0003] The air-cooled air conditioner directly dissipates the heat generated during cooling to the air through the outdoor cooling coil and fan. The heat dissipation coil is usually called a surface air cooler (referred to as a surface cooler), and its structure is an array of multiple sets of copper tubes. Refrigerant flows inside the copper tubes, and dense heat dissipation aluminum fins are expanded outside the copper tubes. The air-cooled air conditioner can cool in summer and heat in winter, realizing one machine with two functions. When heating in winter, the surface cooler absorbs the heat in the air, and is mostly used in household, small or large heat pump units. Because the a...

But this way doesn't work reliably

[0017] To sum up, although there are many ways to utilize condensed water at present, there are still the following defects: or high cost, or poor reliability, or complex structure, or low effective utilization rate

Its volume increases greatly, consumes a lot of water, requires a special water pump, has high cost and complex structure, and has not been widely promoted at present.
