Heat exchanging device

Abstract

Abstract PURPOSE:To heat simultaneously more than two kinds of fluid to be heated by one heating fluid provided in a simple structure by a method wherein a condensing pipe group is provided correspond to a branching pipe line arranged on a pipe line which connects an evaporating pipe group and a condensing pipe group. CONSTITUTION:An evaporating pipe group 5 is arranged in a duct 1 through which a heating fluid is flowed. A heat to be transferred to the evaporating pipe group 5 is transferred by the vapor of a medium to upper headers 8 of a condensing pipe group 9 located in a duct 2 in which fluid to be heated is flowed through pipe lines 7 from upper headers 6 of the evaporating pipe group 5. After the condensing of the vapor, the vapor is flowed into lower headers 4 of the evaporating pipe group through pipe lines 11 from lower headers 10. The evaporating and condensing are performed with natural circulating of the medium. When the heat of high temperature gas G1 flowed through a duct 1 is transferred to two fluids G2 and G3 with such a separated type heat pipe, pipe lines 71 branched from the pipe lines 7 and pipe lines 111 branched from the pipe lines 11 are provided to heat the fluid G3 flowed through the duct 3. Thus, six assemblies of condensing pipe group can be connected to three assemblies of evaporating pipe group, accordingly, two kinds of fluid G2 and G3 are heated simultaneously.
