Heiz und Kühleinrichtung
Das Messsystem besteht aus verschiedenen Heiz- und Kühleinrichtungen (siehe Anlage 3).
Diese Einrichtungen umfassen entgegen dem Vorentwurf im Erstantrag Platten mit
quadratischem Querschnitt (300 mm x 300 mm), anstatt einem kreisförmigen. Dieser Aufbau
wurde wegen der günstigeren Probenpräparation gewählt und ist durch den
Erfahrungsaustausch mit anderen Wissenschaftlern bestätigt§. Um den Vorteil kreisförmiger
Platten mit einem in radialer Richtung homogenen Temperaturfeld nutzen zu können (kein
Eckeneffekt, siehe Fortsetzungsantrag), ist die mittlere Heizplatte („Metering Plate“)
kreisförmig konstruiert und gefertigt. Sie ist für die Erzeugung des eindimensionalen
Wärmestroms durch die Probe zuständig. Die Voruntersuchungen zur Fertigung der
Heizplatte, die aus zwei dünnen Metallplatten und einem dazwischen eingebetteten
Heizleiter besteht, zeigten Inhomogenitäten in der Verteilung des Lötmittel sowie auch im
Temperaturfeld. Dies ist auf die Unterschiede der thermo-mechanischen Spannungen
zwischen den Heizleitern einerseits und den beiden Platten andererseits zurückzuführen. Die
Heizeinrichtung besteht als verbesserte Variante aus nur einer Platte, in die eine Nut gefräst
wird, welche wiederum den Heizleiter vollständig aufnehmen kann. Die entstehenden
Zwischenräume zwischen Heizleiter und Metallplatte wurden durch Lötmittel gefüllt. Die
Heizplatten wurden abschließend geschliffen um die Planparallelität und Ebenheit der
Oberflächen zu gewährleisten. Diese Konstruktion stellt eine optimale Lösung für den
Einsatz in der Messapparatur dar.

Heating and cooling deviceThe measuring system consists of various heating and cooling devices (see Appendix 3).Contrary to the preliminary draft budget in the first application, these facilities include plates withsquare section (300 mm x 300 mm), instead of a circular. This structurewas elected because of more favourable specimen preparation and theExchange of experience with other scientists confirmed §. To take advantage of circularTo take advantage of plates with a homogeneous temperature field in the radial direction (noCorner effect, see continuation application), the Middle plate ("Metering Plate") iscircular designed and manufactured. It is for the production of the one-dimensionalHeat flow through the test charge. The preparatory studies for the production ofHot plate, the two thin metal plates, the other between embeddedHeating conductor consists Inhomogeneities showed in the distribution of the solder as well as in theTemperature field. This is due to the differences of the thermo mechanical stressesbetween the electric on the one hand and on the other hand, the two plates. TheHeating unit consists of plate as a improved variant only a, milled into a Groove in theis, which in turn can fully absorb the heating cable. The resultingGaps between the heating element and metal plate were filled by solder. ThePlates were then ground plane parallelism and flatnessSurfaces to ensure.

A heating and cooling device
The measuring system consists of various heating and cooling devices (see Appendix 3).
Such devices include counter-draft in the initial application plates with
square cross-section (300 mm x 300 mm), rather than a circular. This structure
was chosen because of the favorable sample preparation and is by the
bestätigt§ experiences with other scientists. To the advantage of circular
to use panels with a homogeneous temperature field in the radial direction (no
corner effect, see continuation request), the central heating plate ( "Metering Plate") is
circularly designed and manufactured. It is for the production of one-dimensional
charge heat flow through the sample. The preliminary studies for the production of
heating plate, which consists of two thin metal plates and a sandwiched therebetween
is heat conductor, showed inhomogeneities in the distribution of the solder as well as the
temperature field. This is due to the differences of the thermo-mechanical stresses
caused between the grid lines on the one hand and the two plates on the other. The
heater is the improved version of only one plate into a groove milled
will, in turn, can take the heat conductor completely. The resulting
spaces between heating conductors and metal plate were filled by solder. The
heating plates were finally ground the plane parallelism and flatness of
ensuring surfaces. This construction provides an optimal solution for the
shows used in the measuring apparatus.
