Polymer Mirco-Hollow Fibre Heat Exchangers

他的项目旨在开发、优化和制造适用于各种应用的新型聚合物微中空纤维换热器(PHFHE)。这种重量轻的PHFHE与传统的金属换热器相比，重量最多可减轻50%，导致成本至少降低50%。直径较小(微米)的纤维壁薄，比表面积大，换热强度显着提高。PHFHE可应用于下列领域：1)建筑：用于液体除湿冷却的中空纤维，以及用于空气热回收、空气加热器和风扇盘管的无孔毛细管；2)汽车：汽车散热器，其热功率与传统散热器相同，但重量轻50%；3)电子产品：用于冷却紧凑型电子设备的传热单元；4)水淡化：通过中空纤维膜渗透汽化空气增湿；5)储能：用于封装PCM的非多孔中空纤维可以加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利用的材料，大大减少能源消耗和碳排放。

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.
