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 mold. Said ends of the heat exchanger tubes are sealed such that a tube sheet material to be casted in the mold does not enter the heat exchanger tubes during casting of the tube sheet material. A tube sheet material is casted in the mold for covering the sealing elements. The tube sheet material is hardened in the mold.

Heat exchanger tube sheet, a heat exchanger and a method of manufacturing a heat exchanger tube sheet

The invention relates to an evaporator () for heat exchange between fluids, comprising a housing () having at least one inlet () and at least one outlet () for each fluid, the inlet and outlet for each fluid being connected to one another by a flow path (), the flow path () of a first fluid comprising multiple heat exchange modules () comprising at least one longitudinal hollow tube (), wherein the modules () are arranged in a stack spaced apart from the housing () leaving free a gap (), and wherein a module () is provided with at least one connector () for connecting to a co-operating connector of an adjacent module, such that the gap () 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 vapor phase and a liquid phase of the second fluid and the space () enclosed between adjacent modules in the stack defining a flow path () for a second fluid, parallel to the flow path () for the first fluid, are in fluid communication with each other.

Thermosiphon evaporator

The invention relates to a heat exchanger for heat exchange between fluids, comprising a housing having an inlet and an outlet for each fluid, the inlet and outlet for each fluid being connected to one another by a flow path, the flow path of a first fluid comprising multiple heat exchange modules comprising at least one longitudinal hollow tube, wherein the modules are arranged in a matrix configuration that comprises at least two columns of longitudinal tubes and at least two rows of longitudinal tubes, and wherein a module is provided with at least one connector for connecting to a co-operating connector of an adjacent module, such that the space enclosed between adjacent modules defines a flow path for a second fluid, parallel to the flow path for the first fluid.
