发明名称 Device evaluating thermomechanical fatigue of a material
摘要 A system for cooling and holding a testpiece in an effective manner while the testpiece is subjected locally to high heat flux. The testpiece includes an inside face extended by parallel strips that leave between them channels for passing a cooling fluid, and parallel fins of an intermediate part are inserted between the strips.

主权项 1. A device for evaluating thermomechanical fatigue of a material subjected to heat flux, comprising: a testpiece made of the material and including a hot wall with an outside face to be subjected to the heat flux and an inside face that is extended by parallel strips attached to the inside face and leaving parallel channels between one another; an intermediate part including parallel fins shaped and dimensioned to become inserted in the channels between the strips to define a passage in a vicinity of the inside face of the hot wall for circulating cooling fluid, the passage including a plurality of parallel segments separated by the strips, a section of the passage being defined by engaging the fins in the parallel channels; a support including the testpiece and the intermediate part installed thereon and including duct elements connected to ends of the cooling fluid circulation passage; a cooling fluid circulation circuit connected to the duct elements; and heater means for heating the hot wall.
