Present paper deals with numerical and experimental studies about the heat transportation of a new kind of heat transportation pipe, a double tube with orifices at both ends. Sinusoidal reciprocal flow with frequency f and tidal amplitude Am was given at one end of the heat transportation tube. Heat transportation rate was calculated for f=0.1, 0.8 and 1.0Hz and Am=38.1, 169 and 190mm. The calculated heat transportation rates were compared with experimental ones. We found that the new type of heat transportation pipe can transport about 10 to 100 times heat that the single round tube can transport.
