Abstract
PURPOSE: To obtain a small high performance heating tube for absorber by making a plurality of rows of recesses in the outer wall of a heating tube intermittently in the longitudinal direction and at a predetermined interval in the circumferential direction thereof and making a large number of grooves at least in the outer wall where the recess is not formed. CONSTITUTION: A plurality of rows of recesses 3 of specified depth, e.g. 0.5-5 mm, are made in the outer wall of a heating tube 1 for absorber intermittently in the longitudinal direction and at a predetermined interval in the circumferential direction thereof. And making a large number of grooves at least in the outer wall where the recess is not formed. Absorbed liquid on the surface of the heating tube 1 absorbs steam fed from an evaporator and the concentration thereof decreases but migration in the depth direction does not progress significantly only through diffusion. Stirring takes place in a liquid film upon occurrence of convection and since the concentration is not decreased on the surface of the absorbed liquid, the migration of substance is not retarded. Consequently, a thick liquid film is formed on the surface of the heating tube 1 and stirring is accelerated when circumferential liquid flow passes over the recess 3. Furthermore, the transfer of heat is accelerated by making a large number of grooves 2 in the outer surface having no recess 3 thereby increasing the outer circumferential area.
