Problems solved by technology

[0002] Existing closed cooling towers use spraying water to the outside of the heat exchanger tube bundles, and cool the fluid in the tubes through the evaporation and heat absorption of the water film on the outer surface of the tubes. The temperature is adjusted, and in the transition season, the cooler is also running at full capacity, wasting electricity and water resources

Embodiment 1

[0030] In the transitional season when the temperature and humidity of the external environment are moderate, the cooler is in the mode of adiabatic humidification of the air. At this time, the fan 8 and the atomizing nozzle 2 are in the working state, and the spraying device 6 is in the non-working state. see Figure 1 to Figure 4 , the air humidifier has two shapes, A and B. The arrangement angles of the corrugated fiber humidifier boards in the two air humidifiers are different. The corrugated fiber humidifier board in air humidifier A is vertically arranged, and the air humidifier The corrugated fiber humidifier panels in device B are arranged obliquely. City tap water circulates in the water supply pipe of the atomizing device to supply the sprayed water to the atomizing nozzle 2. The air humidifying device contains a large amount of atomized water droplets. It is close to the wet bulb temperature of the ambient air. At this time, the low-temperature air from the air hum...

Embodiment 2

[0032] When the temperature and humidity of the external environment are high, the cooler is in the spray evaporative cooling mode. At this time, the fan 8 and the spray device 6 are in the working state, the atomization device 2 is in the non-working state, and the spray device 6 is in the heat exchange mode. The coil 5 is sprayed with water so that the outer wall of the heat exchanger tube is covered with a layer of water film. The water film evaporates and absorbs heat under the dual action of the high-temperature fluid in the tube and the high-speed air outside the tube, and relies on the evaporation and heat absorption of the water film to circulate in the tube The fluid cools down, and the spray water outside the pipe wall will flow into the water pan, and the water in the water pan will continue to supply water to the spray device through the circulating water pump, so as to reduce the consumption of water. The spray evaporative cooling mode is suitable for high-temperat...

Embodiment 3

[0034] refer to Figure 5 , 6. The cooler of the present invention is a modular device, and cooler modules can be used in combination according to different heat exchange requirements.

Abstract

The invention relates to a closed adiabatic evaporative cooler. An air humidifying device is arranged at the air inlet of the lower part of the cooler shell, and a heat exchanger coil and a spraying device are arranged on the upper part of the cooler. The air humidifying device is composed of a corrugated fiber humidifier. The corrugated fiber humidifier plate is fixed at the air inlet of the lower part of the cooler shell through the humidifier fixing device, and the atomizing nozzle is installed in front of the corrugated fiber humidifier plate. The atomizing nozzle of the present invention sprays water to the corrugated fiber humidifier plate, and the air entering the cooler evaporates and cools down in the corrugated fiber humidifier plate, so that the air temperature at the outlet of the corrugated fiber humidifier plate is reduced to close to the humidity of the ambient air. The temperature of the bulb greatly reduces the temperature of the air outside the heat exchanger coil, enhances the heat exchange effect, and greatly reduces the water consumption of the cooler in the transition season.

Description

technical field [0001] The invention relates to a closed adiabatic evaporative cooler, which uses air to cool a heat flow medium, and is mainly used for cooling the process circulation fluid of heating equipment such as industrial electric furnaces, power supplies, and motors. Background technique [0002] Existing closed cooling towers use water spraying outside the heat exchanger tube bundles to cool the fluid in the tubes through the evaporation and heat absorption of the water film on the outer surface of the tubes. The temperature is adjusted, and in the transition season, the cooler is also running at full capacity, wasting electricity and water resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a closed-type adiabatic evaporative cooler, and to improve the existing closed-type cooling tower, so that it can be controlled according to the ambient temperature, humidity, initial temperature and final c...
