[Technical field to which the invention belongs]

 The present invention relates to a kind of high-efficiency evaporative heat exchanger, and more particularly to a kind of heat exchanger which can be used for refrigeration and air conditioning products or for industrial use. It is coated with a thin film material, water is attached to this hygroscopic material, and after absorbing the heat in the pipe, it is evaporated at normal temperature. The present invention relates to a device that can achieve the effect of increasing the heat exchange efficiency by lowering the working pressure and temperature of the work.

[Prior art]

 There are two types of conventional cooling systems of a cooler, a gas cooling system and a water cooling system. Among them, the gas-cooled type uses the convection of air to generate a cooling effect, but its cooling efficiency is inferior and therefore it is only applied to equipment with relatively small refrigeration capacity. To apply this to large refrigeration and air-conditioning equipment, a large-sized radiating fan was required, and the length of the cooling pipe of the cooler had to be increased, and the extended portion had to be filled with refrigerant. . Therefore, the production cost is high, the noise is high, and electricity is consumed, which is not economical. On the other hand, the cooling efficiency of the water-cooled type is slightly better than that of the gas type, but it is necessary to install a separate cooling water tank and connect the cooling water tank and the aircraft by pipes. In addition to the labor and time required for installation, the cost and danger of erection were relatively high when installing on high-rise buildings.

[Effect of the invention]

 In summary, the high-efficiency evaporative heat exchanger of the present invention covers the heat-conducting contact surface between the heat transfer media with a hygroscopic thin-film material, attaches water to the hygroscopic thin-film material, and attaches the attached water. It absorbs the heat inside the pipe and evaporates it at normal temperature, which is considered to have a moisture absorbing and moisturizing effect.If water is replenished periodically, the function can be maintained and the amount of water completely evaporated By controlling to be equal to the amount, there is no need to collect and circulate the feedwater, and the present invention achieves the heat exchange by the latent heat change by utilizing the change in the liquid-gas saturation zone of the water. It greatly reduces the working pressure and temperature of the material to be cooled, and therefore has a higher heat exchange rate than known water-cooled or gas-cooled coolers.
