| Abstract: | In this paper, various possible ways of heat conduction of thermos bottles are theoretically diseussed in detail. A concept of critical pressure in the space between the two walls of the thermos is introduced. Methods for calculating different kinds of heat loss are given. Taking the conventional type (No.5) thermos as an example, the authors quantitatively (ealvulated temperatare drops caused by each kind of heat loss in 24 hours time and estimated their influences on the efficiency of heat preservation. A theoretical principle for the desing of thermos bottles is suggested.. And a promising way of improving the heat preservation of a thermos is also proposed. |
