DEVICE AND METHOD FOR DETERMINING THE CONVECTIVE HEAT TRANSFER COEFFICIENT

摘要

The invention relates to a device for determining the convective heat transfer coefficient at a convection surface (1), wherein a first temperature difference between the surface temperature of the convection surface (1) and the surrounding fluid temperature and a second temperature difference between a temperature in the vicinity region (4, 20) close to the convection surface (1) and the surrounding fluid temperature can be determined. The vicinity region (4) is spaced from the convection surface (1) in such a way that the temperature is noticeably influenced by the convection surface (1) by convection.
