EVAPORATION CHAMBER OF LOOP HEAT PIPE Russian patent published in 1997 - IPC

FIELD: thermal engineering; heat transfer from thermally stressed equipment. SUBSTANCE: evaporation chamber has body incorporating side wall 1 and end walls 2, 3. Body accommodates capillary-porous nozzle 4 with blind central channel 5 whose side and end surfaces are in thermal contact with additional internal wall 6 of chamber. Nozzle 4 forms annular clearance 7 with side wall 1 on length restricted by projection 8 of nozzle 4 and clearances 9, 10 with chamber side walls 2, 3, respectively. Longitudinal grooves 11 are made along surface of nozzle 4 which is in thermal contact with internal wall 6 and threaded grooves 12 on contacting surface of internal wall 6 which form integrated system of grooves for conveying steam to clearance 10 that functions as steam header communicating with steam line 13 of loop heat pipe. Annular clearance 7 and end clearance 9 form single space for accumulating liquid coming from condensate line 14. Chamber may be made in the form of truncated cone; the last design form is cylinder turning into truncated cone. EFFECT: improved design. 4 cl, 5 dwg
