Liquid cooling method and device

Abstract

The invention relates to a fluid cooling method and device. The device comprises an air cooler. The air cooler at least comprises finned tubes composed of fluid pipes and fins, wherein cooled fluid circulates in the fluid pipes, and the fins are connected with the outer sides of the fluid pipes, arranged at intervals and composed of flaky thin plates. The single side or two sides of the surface ofeach flaky thin plate are coated with a hydrophilic coating layer or hydrophilic coating layers. The flaky thin plates are in contact with circulating air. During cooling of the air cooler to the fluid, water is distributed to the finned tubes in the time frame of high atmospheric temperature, and in the time frame of low atmospheric temperature, no water is distributed to the finned tubes, or water is distributed to the finned tubes in a segmentation manner. According to the fluid cooling method and device, the surfaces of the fins are coated with hydrophilic coating, uniform and stable water films are formed on the surfaces of the fins in a wind blocking and water distribution manner, in the atmosphere high temperature time frame, water film water vaporization latent heat absorption, forced evaporation and heat exchange are directly carried out on the fins, and the cooling capacity of equipment is greatly improved. The fluid cooling method and device have the beneficial effects of being remarkable in water saving effect, low in investment cost and low in operating cost.

Description

technical field [0001] The invention relates to a fluid cooling method and device, especially for the cooling of circulating cooling water and the condensation of steam in industrial processes, using water evaporation and heat exchange to make up for the lack of cooling capacity of air in high temperature periods, ensuring the cooling cycle of circulating cooling water Utilizing the effect of condensation of steam and achieving the purpose of reducing the scale of the device, saving equipment investment and operating costs, it belongs to the field of industrial water circulation, industrial cooling and air cooling water saving. Background technique [0002] In order to ensure the normal operation of industrial production processes, many processes need to be cooled. Due to its low price, abundant resources, and excellent heat transfer performance, natural water is often used as a heat transfer medium for industrial cooling, called cooling water. Cooling water is the largest ...

Problems solved by technology

In addition, the method of spraying water at the air inlet to reduce the humid air to close to the wet bulb temperature and exchange heat with the fins can also enhance the heat exchange capacity of the fins, but in fact it is only the cooled air that exchanges heat with the fins. Although the cooling capacity has been improved, the heat exchange between the humid air and the fins after water vaporization and cooling still belongs to the method of only heat conduction cooling, and the cooling capacity of water vaporization has not been fully utilized
