Abstract

PURPOSE:To obtain a convection heat flow rate and a radiation heat flow rate accurately and independently by providing a plurality of heat flow sensors having different characteristics in the vicinity of the surface to be measured and computing the outputs of the heat flow sensors by using test constants of the sensors. CONSTITUTION:The heat flow sensor 11 is arranged in the vicinity of the surface to be measured 1. The sensor 11 comprises silicon rubber and the like. The surface area of a heat resisting body 12 is divided into two regions. Thermopiles 13 and 14 are provided in each region. Warm contact points are arranged on one surface and cold contact points are arranged on the other surface. A coating material 16 on one region is treated to obtain aluminum mirror and its emissivity is epsilons2. The other is treated by carbon and its emissivity is epsilons2. A temperature v of the heat resisting body 12 is sensed by a thermocouple 17. The testing constants K1 and K2 in both regions of the heat resisting body 12 are separately obtained by a standard heat flow generator. The outputs Vp1 and Vp2 from both regions of the heat sensor 11 and the temperature v are amplified and inputted to a computing circuit 34 together with a surface emissivity epsilonw of the surface to be measured which is sensed by an emissivity meter 35. Then, they are computed, and displayed on a display circuit 36. Thus, the convection heat flow rate and the radiation heat flow rate are obtained accurately and independently.
