Problems solved by technology
[0004] The object of the present invention is to provide a closed evaporative air cooler to solve the problem that the closed evaporative air cooler in the prior art in the above-mentioned background technology cannot expand the spray range when in use, and the spray uniformity is poor, and it cannot be sprayed on the surface of the heat transfer tube. A uniform and continuous thin water film is formed, which in turn affects the heat exchange effect between the water film and the air, reduces the efficiency of heat exchange, and cannot guide the air flow during air induction, making it impossible to accurately flow to the heat transfer tube, further Problems Affecting the Efficiency of Heat Exchange

The invention discloses a closed evaporation air cooler. The air cooler comprises a heat transfer pipe; the heat transfer pipe is installed at the top of a bracket; and a spraying assembly is arrangedon the upper portion of the interior of an evaporation air cooler body. According to the closed evaporation air cooler, through rotary connection of branch pipes and rubber balls, when a protruding block reciprocates up and down, pull rods can drive spraying heads to rotate in a centripetal and centrifugal reciprocating mode at the same time, so that the spraying range is enlarged and the spraying uniformity is improved; a uniform and continuous thin water film can be formed on the surface of the heat transfer pipe, so that the heat exchange effect of a water film and air is guaranteed, the heat exchange efficiency is enhanced, dust is prevented from entering the evaporation air cooler body and being attached to the outer wall of the heat transfer pipe, and the heat exchange effect is prevented from being affected; and through the arrangement of a flow dividing pipe and through holes, water in a water tank can be evenly bubbled in a large range, so that heat exchange can be formed between the water and the air, the water in the water tank is cooled, the temperature of the circulating water is lower, and the heat exchange quality is further improved.
Description
technical field [0001] The invention relates to the technical field of closed evaporative air coolers, in particular to closed evaporative air coolers. Background technique [0002] The closed evaporative air cooler has the advantages of compact structure, high heat transfer efficiency, low investment, low operating cost, convenient installation and maintenance, etc. It has broad application prospects in oil refining, metallurgy, electric power, refrigeration, light industry and other industries, and is a new direction for the development of air cooling technology. The research on evaporative air cooling began in the 1960s, and it is mainly used in engine jacket water cooling, compressor interstage cooling, lubricating oil cooling, etc. [0003] When the closed evaporative air cooler in the prior art is used, the spray range cannot be expanded, and the spray uniformity is poor, and a uniform and continuous thin water film cannot be formed on the surface of the heat transfer...
