THERMAL CHAMBER FOR TEMPERATURE TESTS OF MATERIAL SPECIMENS

摘要

The invention relates to measuring equipment and can be used at temperature studies materials. The purpose of the invention - improved heat chamber functional and operating characteristics for temperature studies material samples by increasing the measuring accuracy and the convenience of the service. Heat chamber comprises a casing of toroidal shape cavity of which forms a circulation channel intermediate teploholodonositel, wherein successively mounted upstream bottom part of the vessel with liquid nitrogen sngbzhenno- of hollow ribs, between which a gap has zigzag guides, a star-shaped section with a sleeve wound on it heating element and containers specimens arranged in pairs in cross sections circulation channel symmetrically with respect to the vertical axis of the sech Nij, with one of the containers located simulator (test samples) and the temperature sensor is tightly contact with the simulator. The containers are provided with releasable contacts made, as are the containers of the material under investigation images shielding from electrical and magnetic fields. 1 z.p.f-ly. 4 yl. s in
