Method and Measuring cell for the determination of the Thermal - sividad difu materials during the process of transfer of Heat by conduction, with rapid changes of temperature which may include Phase Change.

摘要

Measuring Cell similar to an injection mould for the manufacture of a plate, which comprises a Cavity formed between two metal blocks INTERNAL REMOVABLE and interchangeable with a system of cooling and warming and laterally isolated bodies that hold P Or through an air gap,It restricts the transfer of Heat across the material in the Cavity by the presence of two polymeric bars installed on its sides, which allows for a Rapid System of one-dimensional Heat Transfer in the central area of the plate material.A set of pressure and temperature Sensors installed in fixed form in the bodies of the measuring cell and connected to a Data Acquisition System for the storage of Signals, characterized in that it also comprises a removable deviceRemovable and Reusable repairable Unit called temperature sensor with ceramic or metal tubes assembled in a block carrier to guide and set a group of a minimum of three temperature Sensors in the Cavity is also connected to the Data Acquisition System and With the reusable Plate formed with temperature Sensors to measure the inside CurveAs Warming when the measuring cell is operated at altaternperatura with its heating system. Measuring Cell according to claim 1, characterized by having a Cavity formed by two INTERNAL REMOVABLE and interchangeable blocks made of a Metallic material with which Thermal efficiency is over 100 times that of the study material.File = " EMI 03010433 _ 1" id = "1" = MFI JPEG
