High-efficiency evaporation type radiator

Abstract

The invention relates to a high-efficiency evaporative type cooler, which comprises a water spray device, fin tubes (7) sprayed by the water spray device, a water reservoir (3) arranged under the fin tubes (7), a water supplementing pipe (4) supplementing cooling water to the water reservoir, and an induced draft fan (5) used for driving air to flow; and the high-efficiency evaporative type cooler is mainly characterized in that the fin tubes (7) enclose a hollow and upright cylinder (6) of which the upper port is connected with the suction opening of the induced draft fan (5) and the lower port is sealed by water in the water reservoir (3). Compared with the prior art, the high-efficiency evaporative type cooler not only utilizes the induced draft fan to bring away water vapor formed by vaporizing the cooling water sprayed on the fin tubes, but also forces a great deal of air to scrub the fin tubes to make the fin tubes subjected to good wind cooling function so as to obviously improve the heat exchange efficiency of the fin tubes and make the evaporative type cooler have higher cooling efficiency.

Description

technical field [0001] The invention relates to the construction of coolers in heat exchange equipment, in particular evaporative coolers. Background technique [0002] An evaporative cooler is a device that uses water to absorb latent heat during evaporation to cool the cooled fluid. If the cooled fluid changes from gaseous state to liquid state during the cooling process, then the evaporative cooler is often called "evaporative condenser". In the prior art, the structure of the evaporative cooler includes a water spray device, finned tubes sprayed by the water spray device, the finned tubes are arranged in a box, and the box is provided with ventilation windows. When the evaporative cooler is working, the water vapor in the box is taken away by the fan, so that the cooling water sprayed on the finned tubes evaporates quickly, so that the fluid in the finned tubes is cooled. Since the finned tube has fins, the resistance of the air flowing through the finned tube is relat...

AI Technical Summary

Problems solved by technology

Since the finned tube has fins, the resistance of the air flowing through the finned tube is relatively large, so most of the air in the box will flow along the path of less resistance without passing through the finned tube, and the induced draft fan basically only plays the role of bringing Due to the effect of water vapor in the box, a large amount of air cannot wash the finned tubes, and the air cooling effect on the finned tubes is small, resulting in low heat exchange efficiency of the finned tubes, which restricts the evaporative cooler. Further improvement of the cooling efficiency of the
