Abstract
A Low-grade Thermal Energy Conversion (LTEC) is refocused as one of the renewable energy. For the LTEC and Refrigerator/Heat Pump, it is very important to enhance the heat transfer on heat exchanger though the available temperature deference is smaller than conventional thermal system. In the paper, the micro fabrication surface on plate heat exchanger is proposed as one method for enhanced heat transfer coefficient. The manufacture for micro fabrication surface on plate heat exchanger is introduced using surface configuration. The experimental performance test as evaporator is evaluated on comparison with normal surface heat exchanger using HFC245fa. The results show the boiling heat transfer coefficient of micro fabrication surface was larger than that of normal surface.
