The invention relates to an evaporator (10) for heat exchange between fluids, comprising a housing (12) having at least one inlet (20; 27) and at least one outlet (26, 28; 29) for each fluid, the inlet and outlet for each fluid being connected to one another by a flow path (38; 58), the flow path (38) of a first fluid comprising multiple heat exchange modules (60) comprising at least one longitudinal hollow tube (36), wherein the modules (60) are arranged in a stack spaced apart from the housing (12) leaving free a gap (59), and wherein a module (60) is provided with at least one connector (50) for connecting to a co-operating connector of an adjacent module, such that the gap (59) between the housing and the stack defining at least a liquid recycle zone for containing the second fluid and a phase separation zone for separating a vapour phase and a liquid phase of the second fluid and the space (56) enclosed between adjacent modules in the stack defining a flow path (58) for a second fluid, parallel to the flow path (38) for the first fluid, are in fluid communication with each other.
摘要:
In a method of manufacturing a heat exchanger tube sheet sealing elements are arranged on respective ends of heat exchanger tubes. Said ends of the heat exchanger tubes having the sealing elements are arranged at predetermined positions in a mould. Said ends of the heat exchanger tubes are sealed such that a tube sheet material to be casted in the mould does not enter the heat exchanger tubes during casting of the tube sheet material. A tube sheet material is casted in the mould for covering the sealing elements. The tube sheet material is hardened in the mould.
