his project aims to develop, optimize, and manufacture novel polymer micro-hollow fibre heat exchangers (PHFHE) for various applications . This light weight PHFHE can reduce the weight up to 50% compared with traditional metal heat exchanger, leading to at least 50% cost reduction. The small diameters of the fibres (micrometers) have thin walls and large surface area so heat transfer intensity is significantly increased. PHFHE can be applied in the following sectors: 1) Buildings: holllow membrane fibres for liquid desiccant cooling and non-porous capillaries for air heat recuperation, air heaters and fan-coils; 2) Automotive: car radiators with same thermal power as traditional radiators but 50% lighter; 3) Electronics:heat transfer units for cooling compact electronic devices; 4) Water desalination:air humidification by pervaporation through hollow fibre membranes; 5) Energy Storage: non-porous hollow fibres for encapsulating PCMs can enhance heat transfer for passive cooling and energy storage applications. The implementation of such micro-fibre technology will offer cost effective and recycleable materials significant reduction in energy consumption and carbon emission.

他的项目旨在开发，优化和制造用于各种应用的新型聚合物微中空纤维热交换器（PHFHE）。与传统的金属换热器相比，这种重量轻的PHFHE可以减轻50%的重量，从而降低至少50%的成本。小直径的纤维（微米）具有薄壁和大表面积，因此传热强度显着增加。PHFHE可应用于以下领域：1)建筑：用于液体干燥剂冷却的中空膜纤维和用于空气热回收、空气加热器和风机盘管的无孔毛细管；2)汽车：汽车散热器，与传统散热器具有相同的热功率，但重量轻50%；3)电子产品：用于冷却小型电子设备的传热装置；4)海水淡化：通过中空纤维膜渗透蒸发空气加湿；5)储能：用于封装pcm的无孔中空纤维可以增强被动冷却和储能应用的传热。这种微纤维技术的实施将提供具有成本效益和可回收的材料，大大减少能源消耗和碳排放。
