It is requested to develop a small and highly efficient heat exchanger for small size energy equipment such as fuel cells and CO_2 heat pumps. In the present study, the high pressure resistant micro-channel stacked heat exchanger had been developed The heat transfer area for each volume of this device is quite large. Since the distance between the micro-channels in the device is small, the thermal resistance is small. This device can bear for very high pressure condition since the device is main factored by the diffused bond method Due to the very high pressure resistance, this device can be used for high flow rate condition with boiling and condensation. As the results, it is clarified that above features make the device to archive very high performance more than hundred times larger heat transfer rate than the existing heat exchanger.
