<p>PROBLEM TO BE SOLVED: To provide a heat conductive device for ice manufacture which is excellent in heat conductivity by restraining a dry face from occurring at the liquid film of a water flowing down on a heat conductive plate. SOLUTION: A heat conductive device 1 is equipped with a heat conductive plate 2 having a pipe 8 being meandering while reciprocating in horizontal direction and forming a wall by a plate 2 between the straight sections of a pipe running parallel with each other and its periphery, and a sprinkler 3 sprinkling water and letting it flow down the top end of the heat conductive plate 2. The heat conductive plate 2 is made of aluminum and is manufactured by roll bonding method, and its pipe is circular with one part of the circumferential face rising from the board face. When cooling the liquid film 7 of water flowing down the heat conductive plate 2 by the refrigerant flown through the pipe 8, the liquid film 7 hits upon the pipe 8 and spreads sideways, so it counteracts the contracting force by the surface tension of the liquid film 7, thus preventing the dry face of the liquid film 7 from occurring.</p> |
