Abstract: We present experimental results on heat transfer between plane parallel surfaces of samples separated with microscopic vacuum gap. Radiative heat flux between metallic samples exceeding 50 times heat flux between black surfaces was observed for gaps of several micrometres at temperatures below 50 K. Comparison with near field theory of radiative heat transfer is presented.
Keywords: heat transfer; microscopic distances in vacuum
