For sampling recovering organisms from the deep sea with maintaining their ambient temperature, it is necessary to investigate adiabatic materials for deep-sea use. It is also necessary to predict a temperature change inside a sampler covered with an adiabatic material for the best isothermic design. Therefore, we have to know the heat transfer phenomenon of inside water of the sampler. Although there are many examples obtained theoretically and experimentally concerning with the heat transfer for convection inside closed containers, it cannot be said that each result corresponds with the others. In this paper, the heat-transfer coefficients for convection on inside and outside surfaces of the closed container set up in an uniform flow were obtained experimentally. Then, the temperature change of the water inside the container covered with the adiabatic material was predicted using the above heat transfer coefficients. To predict the temperature change of the inside water, the lumped-heat-capacity analysis method and the numerical analysis method for heat flow were examined. The lumped-heat-capacity analysis was found to be sufficiently effective for this experimental model. These results were applied for the prediction of the temperature change inside closed container recovered from the deep sea, and this application was also certified to be effective by the sea test using the manned submersible "SHlNKAI2000".
