Integrated-flow evaporative cooler

Abstract

The invention discloses an integrated-flow evaporative cooler. A plate type heat exchanger is adopted, channels between plates are in the left-right direction, and natural wind hole areas opposite tothe channels between the plates are arranged in the positions, on the left and right sides of the heat exchanger, of a shell correspondingly. According to the integrated-flow evaporative cooler, a traditional centralized wind inlet mode is changed into a dispersed ventilation mode, and in addition, a great amount of natural wind can be utilized; plate type heat exchanging units are adopted, the natural wind flow direction is consistent with the direction of channels between the plate type heat exchanging units, and the number of natural wind ducts of the positions, on the two sides of the heatexchanger, of the shell is further increased; and in addition, the height of the natural wind ducts is basically equal to that of the heat exchanger, the wind resistance is reduced, the ventilation area is increased, the wind volume is increased, the water accumulating phenomenon is greatly relieved, the water falling speed is greatly increased, the efficiency of heat exchanging between the heatexchanger and water is greatly improved, accordingly, the effect of heat exchanging between the water and the heat exchanger is obviously improved, and the work efficiency of the evaporative cooler isobviously improved. The new heat exchanging mode further has outstanding water-saving and energy-saving effects.

Description

technical field [0001] The present invention relates to an evaporative cooler. Background technique [0002] According to different airflow directions, the existing evaporative coolers are generally divided into three types: forward flow type, counter flow type and cross flow type. The spray water flow of the downstream evaporative cooler is in the same direction as the wind flow, and the wind resistance is small, so the energy consumption is low. The main disadvantage is that the contact between the spray water and the wind is not sufficient, so the heat transfer efficiency is low, and the evaporative cooling effect is difficult to achieve. goal of satisfaction. On the other hand, the downstream evaporative cooler also has the disadvantages of complex structure and large footprint. Due to the reverse operation of the spray water flow and the air flow, the counter-flow evaporative cooler has the advantage of sufficient water and air mixing, but due to the centralized venti...

Problems solved by technology

In practical applications, maintenance and inspection are inconvenient after such structures have internal fouling and dirty clogging.

For example, the blockage or partial blockage of the nozzle is not easy to be found. Generally, when it is serious enough to significantly affect the cooling effect, dismantling and maintenance is carried out. First, the circulating fan is moved by a crane or manually, and the steam trap is removed, and then enters the evaporation through the installation place of the circulating fan. Maintenance or replacement of spray nozzles in the cooler is not only labor-intensive, but also poses a great risk to operational safety, and usually requires production to be stopped for 1-2 days

Therefore, the existing evaporative coolers usually have low cooling efficiency due to lack of maintenance
