Abstract
An extended blackbody source with cavity effect realized bx gravity heat pipe is reported in this paper, which has an operating temperature range of 40°C to 150°C. The diameter of its working area is 150 mm. THERMO TRACER 6T61 is used to measure the temperature distribution over the working area. The results show that the maximum temperature difference within ninety eight percent of the working area is less than 1.4°C. The integrated emissivity of the extended blackbody source to a concentric circular detector is 0.996. This extended source has advantages of relatively good temperature uniformity, simple construction, and low cost.
