DEVICE FOR COOLING AND DEHUMIDIFICATION OF GASEOUS ATMOSPHERE Russian patent published in 2002 - IPC

FIELD: applicable in condensers for conditioning of atmosphere in a confined space, for example, space orbital stations, vehicles operating on hydrogen fuel, ecologically pure research systems of science and production, in biology and oceanology. SUBSTANCE: device has a sealed body with inlet and outlet pipe connections, hotwell, heat exchanger and wicks, the heat exchanger is made in the form of two coaxially arranged cooling jackets: the external and internal ones with a cooler installed between them in the with a cooler installed between them in the form of two coaxially arranged pipes, the external and internal jackets are provided with annular distribution and condensate headers and multiple-thread screw grooves for refrigerant, and in the gap between the cooler pipes there are continuous multiple-thread spiral ribs of the threaded type, slotted spiral passages for gaseous atmosphere are provided between their side surfaces, the directions of the spirals of the slotted passages and screw grooves coincide, the external and internal cooling jackets have separate feeds and taps that are tangential to the annular headers, and the hydraulic conductance of the refrigerant paths is constant; besides, developed annular grooves are provided in the entire length of the condensate and distribution headers, they are arranged at the beginning and end of the cooler respectively. EFFECT: improved operating characteristics of the device, reduced time of cooling of the flow of gaseous atmosphere, intensified cooling of it and separation of condensate, minimized noise, enhanced reliability. 6 dwg
