Plate type evaporation air cooler

Abstract

The invention relates to a sheet vaporizing air cooler, which comprises: a heat transmission element, a fan, a box, and a spray device, wherein the top of box has wind inlet and wind outlet through to the chamber of box; the wind inlet is mounted with sheet heat transmission element, above which the spraying device is mounted; the wind outlet is mounted with wind guider. The heat transmission element is sheet beam; the inlet sheet beam uses leeward film distributing method that the gravity direction of spray water is the same with wind direction; the surface of sheet beam at the wind inlet forms water film by sprayed water, to strengthen the heat transmission, with high efficiency.

Description

technical field [0001] The invention relates to a plate-type evaporative air cooler, which adopts corrugated plates as heat transfer elements, utilizes evaporation to enhance heat transfer, and can replace the traditional tube-type evaporative air cooler. Background technique [0002] The evaporative air cooler in the prior art is a tubular structure, and the film is arranged against the wind. The wind direction is from bottom to top, and the direction of water film formation is from top to bottom. When the film is placed against the wind, the greater the wind, the more uneven the water film Even the water film cannot be formed, and when the wind speed is small, the energy consumption of the air cooler will increase and the heat transfer efficiency will be low. [0003] Therefore, the evaporative air coolers in the prior art generally have the disadvantages of low heat transfer efficiency, heavy weight, fouling, dust accumulation, short life, water leakage and large footprin...

AI Technical Summary

Problems solved by technology

[0002] The evaporative air cooler in the prior art is a tubular structure, and the film is arranged against the wind. The wind direction is from bottom to top, and the direction of water film formation is from top to bottom. When the film is placed against the wind, the greater the wind, the more uneven the water film Even the water film cannot be formed, and the air cooler consumes more energy and has low heat transfer efficiency when the wind speed is small

[0003] Therefore, the evaporative air coolers in the prior art generally have the disadvantages of low heat transfer efficiency, heavy weight, fouling, dust accumulation, short life, water leakage and large floor space.

At the same time, the heat exchange tubes of the evaporator tube bundle are bare tubes. Once the water is cut off, the heat exchange performance will drop sharply, which cannot meet the process requirements. Even in the cold winter, the water cannot be cut off, and the energy consumption is large.

The above problems are particularly prominent in the process of large-scale equipment
