A generator 20 for an absorption chiller (1 fig 1) has a bath 21 for receiving a refrigerant mixture. The bath has at least one side wall 26, 27, and each side wall has a plurality of laminar heat exchangers 29. Each heat exchanger has a rim 30 from which extends at least one heat exchange fin 31. The laminar heat exchangers are stacked together with the at least one fin extending away from the bath. The rim of each heat exchanger may include many extending fins, and the fins of one heat exchanger may interdigitate or stagger with respect to the fins of an adjacent heat exchanger. The bath may contain a refrigerant mixture that may be heated by a burner 32, and a flue pipe 22 may carry heat from the burner over the heat exchange fins that may extend towards the centre of the flue pipe. The laminar heat exchangers may also extend from the bath outer side wall. The invention also relates to an absorption chiller using such a generator.
