<P>PROBLEM TO BE SOLVED: To provide an exhaust gas heat collector and an absorption type freezer improved in the fluidity of an absorption liquid in a heat transfer tube. <P>SOLUTION: In the absorption type freezer, an exhaust route 17 for the exhaust gas discharged from a combustion chamber of a hot regenerator 5 is provided with an exhaust gas heat collector 40 which heats a rare absorption liquid that flows from an absorbing device 2 to the hot regenerator 5 by the exhaust gas. The exhaust gas heat collector 40 includes a plurality of heat transfer tubes 43 which are arranged orthogonal to the flow direction of the exhaust gas in a heat exchanging chamber 40A which is a part of the exhaust route 17, and headers 42A and 42B provided at ends of the heat transfer tubes 43. Return piping 49 is provided which connects upper surfaces 42A1 and 42B1 of the headers 42A and 42B with the hot regenerator 5 returning the gas accumulated in the headers 42A and 42B to the hot regenerators 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
