ABSTRACT:
An absorption type refrigerator including a generator having an improved heat-exchange efficiency and which is compact and economical. The generator is constructed using a heat-exchanger made up of a bellows-fin formed by consecutively bending a thin plate into a wave-like form and seal plates attached to ends of the bellows-fin for sealingly separating chambers disposed on opposite sides of the bellows-fin. In constructing the generator using the heat-exchanger, the bellows-fin is transversely arranged so that a lower chamber is used as a combustion chamber and an exhaust path for a burner whereas a diluted solution is introduced into an upper chamber and discharged therefrom for circulation after generating vapor refrigerant and being converted into concentration solution. Alternatively, the bellows-fin is vertically arranged so that one of the chambers defined by the bellows-fin is used as the burner combustion chamber and exhaust path in which gas flows vertically from a lower portion to an upper portion thereof whereas the diluted solution is dripped vertically from an upper portion to a lower portion of the other chamber to form liquid layer falling film to be boiled and evaporated to generate vapor refrigerant. Then the concentration solution is discharged from the lower portion of the chamber for circulation.
