Polymeric hollow fibre heat exchangers are the new alternative to common metal heat exchangers. These heat exchangers provide advantages, such as low weight, corrosion resistance, easy shaping and machining. Moreover, they consume less energy during their production. Therefore, they are environmentally friendly. The paper deals with shell & tube heat exchangers, which consist of hundreds of polymeric hollow fibres. The structure of the heat transfer surfaces has a significant influence on the effectivity of the use of the heat transfer area that is formed by the polymeric hollow fibres. The study gives a comparison of heat exchangers with an identical outer volume. The difference between them is in the structure of the heat transfer insert. One of the presented heat exchangers has fibres that are in-line and the second heat exchanger has staggered fibres. The study also pays attention to the difference in differential pressures caused by the difference in the structure of the heat transfer surfaces.

“…They concluded that the overall heat‐transfer coefficients were comparable to the typical values of metallic falling film heat exchangers when tested at multiple‐effect distillation (MED) conditions. Some other researchers also found that the PHXs are cost saving in manufacture processes and heat‐transfer applications, which shows that the PHXs have good commercial application potentials in many aspects such as automotive radiators, electronic systems, heat recovery, evaporating and condensing applications, solar water heating, and water desalination process. Besides, the merits of easy of construction and manufacturing, low installation costs, ability to operate at high brine temperatures without fear of the effects of scale formation, use of acid cleaning, and virtual elimination of in‐leakage problems, and so forth are also included when using plastic heat exchangers.…”

Heat‐transfer characteristics of polymer hollow fiber heat exchanger for vaporization application

The heat-transfer characteristics of polymer hollow fiber heat exchanger were investigated by analyzing the heattransfer coefficient (HTC) and the heat-transfer resistance (HTR) distributions of both the lumen side and the shell side. The influences of the fiber wall thickness and the polymer thermal conductivity on the heat-transfer performance were studied numerically based on the experimental validated simulation model. It is found that the original overall HTC value is below 1032 W/m 2 ÁK and the HTR is focus on the fiber wall. However, if enhancing the polymer thermal conductivity to be higher than 1.0 W/mÁK and/or lowering the fiber wall thickness to be less than 0.1 mm, the overall HTC could be improved to over 2000 W/m 2 ÁK, which indicates that the fiber wall HTR is no longer the limiting factor of the polymer hollow fiber heat exchanger applications.

Access to pure water is a very topical issue today. Desalination represents a promising way of obtaining drinking water in areas of shortage. Currently, efforts are being made to replace the metal components of existing desalination units due to the high corrosivity of sea water. Another requirement is easy transportation and assembly. The presented solution combines two types of polymeric hollow fibers that are used to create the distillation unit. Porous polypropylene hollow fiber membranes have been used as an active surface for mass transfer in the distillation unit, while non-porous thermal polypropylene hollow fibers have been employed in the condenser. The large active area to volume ratio of the hollow fiber module improves the efficiency of both units. Hot water is pumped inside the membranes in the distillation unit. Evaporation is first observed at a temperature gradient of 10 °C. The water vapor flows through the tunnel to the condenser where cold water runs inside the fibers. The temperature gradient causes condensation of the vapor, and the condensate is collected. The article presents data for hot water at temperatures of 55, 60, and 65 °C. Optimization of the membrane module is evaluated and presented.
