Abstract
Устройство для измерения теплопроводности трубчатых образцов в канале ядерного реактора, содержащее корпус, радиатор, выполненный из меди в виде полого цилиндра с продольным пазом по образующей и установленный в корпусе с зазором, игольчатые опоры с экранами, размещенные в торцовых частях радиатора, радиационный нагреватель из тугоплавкого материала, установленный по оси радиатора на указанных игольчатых опорах, и термопары, размещенные на внутренней и наружной поверхностях образца, выполненного в виде кольцевых участков, размещенных по плотной посадке в центральной части радиатора с зазором между нагревателем и внутренней поверхностью образца, отличающееся тем, что, с целью повышения точности и производительности измерений, радиационный нагреватель выполнен в виде эксцентрично расположенных цилиндров равного внешнего диаметра в количестве n+1, где n - число кольцевых участков образца, и отделенных друг от друга кольцевыми проточками, а устройство снабжено приводом, соединенным с верхней игольчатой опорой, и упругим элементом, например пружиной, соединенной с нижней игольчатой опорой и торцом радиатора, при этом игольчатые опоры установлены в радиаторе по ходовой посадке для обеспечения перемещения нагревателя вдоль оси радиатора.A device for measuring the thermal conductivity of tubular samples in the channel of a nuclear reactor, comprising a housing, a radiator made of copper in the form of a hollow cylinder with a longitudinal groove along a generator and installed in a housing with a gap, needle supports with screens placed in the front parts of the radiator, a radiation heater made of refractory material installed along the axis of the radiator on the specified needle supports, and thermocouples placed on the inner and outer surfaces of the sample, made in the form of annular sections, placed for a tight fit in the central part of the radiator with a gap between the heater and the inner surface of the sample, characterized in that, in order to improve the accuracy and performance of measurements, the radiation heater is made in the form of eccentrically located cylinders of equal outer diameter in the amount of n + 1, where n is the number ring sections of the sample, and annular grooves separated from each other, and the device is equipped with an actuator connected to the upper needle support and an elastic element, for example, a spring connected to the lower needle support and the end of the radiator, while the needle support is installed in the radiator on the running fit to ensure movement of the heater along the axis of the radiator.
