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.

The invention discloses a high-efficiency water-saving valve with two-stage control. The working device is a conical water pipe (1), a conical water plug (2), and a rubber spring with variable stiffness (3). The control device is a water plug pull rope (5 ), foot pedal (6), reset rubber spring (7), auxiliary device is water valve bottom cover (4), positioning collar (8), heel shaft (9), ground pit (12), the right side of the valve It is water inlet (10), and the left side is water outlet (11). The present invention designs a two-stage control high-efficiency water-saving valve. First, it can avoid the second pollution of human hands. When washing and washing, it is not necessary to control the valve with hands, but to control the water outlet and stop water through the control device with feet; second, it can efficiently save water. Water, people can save up to 30‑50% of water when washing their hands or face with detergent; the third is to meet individual water needs, either large flow of water or small flow of water, both Water can be used for a short time or for a long time.

The invention discloses a hierarchical electric-control high-efficiency water saving device. A working part is formed by a conical plastic water pipe (1) and a conical steel water plug (2), a transmission part is formed by a steel plastic spring (3), a cylindrical silicon steel sheet group (4), a small screw coil (6) and a large screw coil (7), a control part is formed by a pedal plastic plate (8), a small coil switch (9), a large screw coil switch (10) and a variable rigidness return spring (11), and an auxiliary part is formed by a thin rubber cover (16), a water valve bottom cover (5), a white rubber blanket (12) and a sewer pipe (15).
