The invention relates to a heat transfer device, used in particular in conjunction with fuel cells and absorption refrigeration systems. The aim of the invention is to develop a heat transfer device for use in conjunction with absorption refrigeration systems, which can be operated using the discharged air of a fuel cell, does not require increased installation space, does not exhibit increased thermal expansion and/or the thermal stresses associated with the latter and which significantly reduces production, assembly and maintenance costs, at the same time considerably minimising the inevitable flow losses that occur and in addition preventing the crystallisation of the solvent, thus enabling the extremely efficient generation of heat and cold. To achieve this, the inventive device is characterised in that it is equipped with a high-temperature generator (1) comprising a solvent inlet and a solvent outlet and a low-temperature heat exchanger (4) comprising a cooling water inlet and a cooling water outlet. A plurality of tubular circular segments (10), each having an arc angle ranging between 300 DEG and 330 DEG , are located above one another and adjacent to one another both in the high-temperature generator (1) and in the low-temperature heat exchanger (4), in such a way that their free ends are connected in a gas-tight and liquid-tight manner to the holes of two perforated metal sheets (12), an inflow sheet and an outflow sheet, said sheets being fixed on all sides in the heat transfer annular chamber (11) of the heat transfer container (9). |
