ADSORPTION PUMP Russian patent published in 2002 - IPC

FIELD: cryogenic engineering. SUBSTANCE: invention relates to adsorption pumps designed for maintaining vacuum by absorbing molecules of gas from closed volumes. Vessel has radial hollow ribs uniformly spaced in inter-wall space of vessel with intersection of heat insulation layers. Inner spaces of ribs have inserts made of capillary porous titanium and laid through inner space of vessel. On outer surface of ribs additional adsorbent member is secured being provided with built-in heater made in form of heating element of current-conducting film laid layers of adsorbent. EFFECT: provision of stable cooling of adsorbent at coolant liquid phase temperature, improved efficiency of operation of adsorbent and heat insulation. 2 dwg
