Background
The surface evaporation type air cooler is a high-efficiency condensing and cooling device which integrates the processes of water cooling, air cooling and mass and heat transfer. The surface evaporation type air cooler can simultaneously utilize the latent heat and the sensible heat of cooling water, the heat transfer effect is improved by 34 percent compared with that of a water cooler, the water saving is obvious, and the operation is stable.
The working process of the surface evaporative air cooler is that a pump is used for conveying circulating cooling water to a spraying water surface above a horizontally placed light pipe bundle, and the cooling water is downwards sprayed to the surface of a heat transfer pipe, so that a continuous and uniform thin water film is formed on the outer surface of the pipe; meanwhile, air is sucked from an air inlet at the lower part of the equipment by a fan, so that the air flows from bottom to top. At the moment, the heat exchange outside the heat transfer pipe is mainly realized by absorbing a large amount of heat through the rapid evaporation of the water film on the outer surface of the heat transfer pipe except for the sensible heat transfer between the water film and the air flow, so that the heat transfer outside the pipe is enhanced.

The leak detection process of the tube bundle is complex, the process is complex, the repeatability is high, the consumed time is long, and the leak detection needs to enable the corresponding surface evaporation type air cooler to be quit from operation, so that the production is influenced. In addition, considering air cooler structure particularity, the port of all pipes is located inside the pipe case, if in the link of checking for leaks, the mistake will not leak the pipe stifled, will reduce actual heat radiating area, may lead to the heat transfer volume can't satisfy the load requirement, and the harm is very outstanding.
