Abstract

This invention belongs to the field of refrigeration and evaporative cooling technology, and particularly relates to a cascaded dual-circulation magnetic water film evaporative cooling device. The cascaded dual-circulation magnetic water film evaporative cooling device includes first air inlets on the left and right side walls; a controller is also installed on the side wall of the mounting box. This invention constructs a cascaded dual-circulation water system by setting up a first water tank, a second water tank, and two corresponding evaporative filters. Air passes through a dual-temperature zone water film for two heat and moisture exchanges. The first water tank is equipped with an independent cooling fan and an insulation layer to form a low-temperature water storage zone, while the second water tank serves as a normal-temperature water supply unit. The two water films create a temperature gradient, significantly extending the contact path and time between air and water, and significantly improving the heat and moisture exchange efficiency. Compared to traditional single-stage evaporative cooling devices (cooling by approximately 3 degrees Celsius), this device can achieve a cooling of 78 degrees Celsius, more than doubling the cooling effect.
