专利汇可以提供Gradient cone thermal radiation sensor专利检索,专利查询,专利分析的服务。并且A conical cavity radiometer having a thin-walled thermal receptor cone secured about its open base end to a surrounding hollow heat sink which shields the cone against response to its ambient thermal environment and maintains the base end of the cone at an equilibrium temperature. Thermal radiation entering the open cone end creates a temperature differential between the cone ends proportional to the incident thermal radiation flux. This temperature differential is sensed by temperature sensors attached to the cone ends and is converted to an electrical signal which is an analog of the incident radiation flux. The radiometer is characterized by rapid attainment of thermal equilibrium, high sensitivity, and rapid response to changes in incident radiation flux.,下面是Gradient cone thermal radiation sensor专利的具体信息内容。

1. In a conical cavity radiometer, the combination comprising: a thermal receptor cone having an open base end and an opposite apex end; a heat sink disposed in thermally conductive relation to said base end of said cone including a hollow thick-walled heat sink body having a central chamber containing said cone in a manner such that said body completely surrounds said cone circumferentially from its base end to its apex end; and the portion of said cone rearwardly of said base end being spaced from the wall of said chamber.
2. A radiometer according to claim 1 including: means for circulating a coolant in heat transfer relation to said heat sink.
3. In a conical cavity radiometer, the combination comprising: a thermal receptor cone having an open base end and an opposite apex end; a heat sink disposed in thermally conductive relation to said base end of said cone including a hollow thick-walled heat sink body having a central chamber containing said cone in a manner such that said body completely surrounds said cone circumferentially from its base end to its apex end; the portion of said cone rearwardly of said base end being spaced from the wall of said chamber; means for circulating a coolant in heat transfer relation to said heat sink; and means for producing an electrical output representing the temperature difference between the ends of said cone.
