摘要：
A new cellular heat pipe flat solar energy collector is introduced, and the thermal performance of the new solar heater comprised by water heat pipe or acetone heat pipe is tested. The results are compared with the performance of the evacuated glass tube solar heater. It is found that: the heat loss coefficient of the cellular heat pipe flat solar heater is 54% less than that of the evacuated glass tube solar heater, while the daily average efficiency of solar absorbency is 15% higher, when the water temperature of heating is lower than 65°C. In conclusion, the thermal performance of such new solar heater is better than that of evacuated glass tube solar heater or ordinary flat solar heater, both of which are still popular in China. This new solar energy application promises to be a prosperous technology.
