This paper is an experimental investigation on forced convective boiling in a mini-tube. First, frictional pressure drops were measured in adiabatic condition. Next, heat transfer coefficients were measured in condition of constant heat fluxes. These data were compared with those in conventional tubes. The inner diameter of test tube is 0.51mm, and the test fluid is HCFC123. Ranges of the experimental parameters are as follows: the pressure P=0.1 - 0.3MPa, the mass flux G=150 - 500kg/m^2s, the heat flux q=10 - 30 kW/m^2, the vapor quality x=0.06-1.0. The pressure drops and heat transfer coefficients were lower than those in conventional tubes.
