The water-cooled heat exchange efficiency is high, and the stable internal temperature and indoor temperature can be maintained even in high temperatures in summer. However, the structure of the device is complicated and high in cost, and is not applicable in water-deficient areas.
源于水资源的紧迫性,缺水地区空冷技术已得到应用,空冷以其显著的节水效果被人们所关注,同时其装置构造简单、造价低,但是在夏天高温时,对于低温工艺介质的冷却,特别是要求工艺介质出口温度冷却到接近环境湿球温度时,普通空冷系统冷却效率降低,难以做到。近年来随着冷却技术的深化发展,一种新型空冷系统——喷淋水式蒸发空冷系统得以推广应用。Due to the urgency of water resources, air-cooling technology has been applied in water-scarce areas. Air-cooling has attracted people's attention because of its remarkable water-saving effect. At the same time, its device structure is simple and low in cost, but in the summer, it is low-temperature process medium. Cooling, especially when the process medium outlet temperature is required to cool to near the ambient wet bulb temperature, the cooling efficiency of the conventional air cooling system is lowered, which is difficult to achieve. In recent years, with the deepening of cooling technology, a new type of air cooling system, spray water evaporative air cooling system, has been promoted and applied.
中国实用新型专利CN 201488409 U,名称为干湿混合冷凝器,包括散热器、供水管、水泵、喷管嘴和风机,水泵的工作启动与关闭通过温度传感器从制冷剂流道冷媒管采集温度信号,当超过标准工况时启动水泵喷洒,以湿工况工作,温度传感器从制冷剂流道冷媒管采集温度信号低于标准工况时关闭水泵,保持干式工况运行,通过水泵增压喷洒雾化水,不仅使散热器具有显热交换,而且还有传质交换,部分水蒸发成水蒸气,气化潜热带走大量热量。China utility model patent CN 201488409 U, the name is dry and wet mixed condenser, including radiator, water supply pipe, water pump, nozzle nozzle and fan. The pump starts and shuts down. The temperature sensor collects the temperature signal from the refrigerant channel refrigerant pipe. When the standard working condition is exceeded, the water pump is sprayed to work in wet working condition. When the temperature sensor collects the temperature signal from the refrigerant flow channel refrigerant tube and the temperature is lower than the standard working condition, the water pump is turned off, the dry working condition is maintained, and the water pump is pressurized. The atomized water not only makes the radiator have sensible heat exchange, but also has mass transfer, some water evaporates into water vapor, and the gasification subtropical zone takes a lot of heat.
但是,上述现有技术对散热片直接洒水方式的辅助冷却装置,在夏天时可以提高冷却效率,但经过长时间运行,散热器表面容易附着水垢、水锈等,因此导致热交换效率降低或散热片腐蚀等不利情况。However, the above-mentioned prior art auxiliary cooling device for directly spraying the heat sink can improve the cooling efficiency in the summer, but after a long period of operation, the surface of the radiator is likely to adhere to scale, rust, etc., thereby causing a decrease in heat exchange efficiency or heat dissipation. Unfavorable conditions such as corrosion of the sheet.
中国CN 100572989 C公开一种冷凝器的辅助冷却装置,在冷凝器的散热片附近、在距散热片一定距离的位置上设置冷却垫,在冷却垫上流下冷却水以冷却冷凝器的吸入空气。在冷却垫的上部设置洒水桶,在下部设置排水桶,洒水桶和排水桶之间配置有用于使冷却水循环的泵,这样水不直接喷在散热器表面上,不会在散热片表面上附着水垢、水锈等,但是其辅助冷却装置采用冷却垫,在使用一段时间后,表面上容易附着土、尘埃等脏物,造成过滤器堵塞而降低冷却效率,同时容易滋养细菌等;另一方面,冷却水直接淋在冷却垫上,在冷却垫表面上会 形成一层水膜,这层水膜和冷却垫会极大的增加风机的阻力;冷却水循环使用,也增加了水泵的功耗。China CN 100572989 C discloses an auxiliary cooling device for a condenser. A cooling pad is arranged at a distance from the heat sink near the heat sink of the condenser, and cooling water is drained on the cooling pad to cool the suction air of the condenser. A sprinkler is arranged on the upper part of the cooling pad, and a drain bucket is arranged in the lower part, and a pump for circulating the cooling water is arranged between the sprinkling bucket and the drain bucket, so that the water is not directly sprayed on the surface of the heat sink, and does not adhere on the surface of the heat sink. Scale, rust, etc., but the auxiliary cooling device uses a cooling pad. After a period of use, dirt, dust, and the like are easily adhered to the surface, causing clogging of the filter to reduce cooling efficiency and easily nourishing bacteria; The cooling water is directly poured on the cooling pad, and will be on the surface of the cooling pad. A layer of water film is formed. This layer of water film and cooling pad will greatly increase the resistance of the fan; the cooling water circulation will also increase the power consumption of the pump.

When T>T 0 , the controller 7 controls the solenoid valve 6 to be opened. At this time, the air entering from the air inlet is sprayed by the atomizer 3, and the embodiment is in the evaporative cooling mode, and the flow rate of the cooling water is cooled by the controller 7 according to the controller. The temperature and heat exchange efficiency at the air outlet are calculated and calculated by the controller 7 according to the calculated value of the flow rate by controlling the opening angle of the solenoid valve 6. As the ambient air temperature increases, the amount of water spray is controlled. Reduce the air to near its wet bulb temperature (relative humidity 95%).
