Abstract: |
A counterflow air-water heater exchanger with same differential temp at each cross-section is composed of the parallelly arranged multiple finned water pipes whose both ends are connected to water trunks used as water inlet and outlet tranks, and the enclosure with air inlet and outlet for surrounding all water pipes in it. The air flows through the enclosure in the direction different from that of water flowing in the water pipes. Its advantages are low resistance, and high heat exchange performance. |
