Abstract
Description
Die Erfindung betrifft einen Thermostat mit einem Metallblock, der eine Aufnahmebohrung insbesondere für ein Probengefäß aufweist und an dem eine Heizeinrichtung angebracht ist.The invention relates to a thermostat with a metal block, which has a receiving bore especially for a sample vessel and on which a heater is attached.
Ein derartiger Thermostat ist bereits im Handel. Er dient zur gleichmäßigen Beheizung von Reagenzgläsern. Die Heizeinrichtung besteht aus elektrischen Heizspiralen, die elektrisch isoliert am Metallblock angebracht sind.Such a thermostat is already on the market. It serves for even Heating test tubes. The heater is there Made of electrical heating coils that are electrically insulated on the metal block are attached.
Sollen solche Reagenzgläser jedoch nicht beheizt, sondern gekühlt werden, so kann der im Handel befindliche Thermostat nicht benutzt werden, sondern die Reagenzgläser müssen in einem besonderen, z. B. einem Kompressorkühlgerät eingesetzt werden.However, such test tubes should not be heated, but cooled the commercially available thermostat cannot be used but the test tubes must be in a special, e.g. B. a compressor refrigerator.
Der Erfindung liegt die Aufgabe zu Grunde, den im Handel befindlichen Thermostat weiterzubilden und auch zu Kühlzwecken verwendbar zu machen.The invention is based on the object, those on the market Develop thermostat and can also be used for cooling purposes close.
Zur Lösung dieser Aufgabe ist ein Thermostat der eingangs erwähnten Art erfindungsgemäß dadurch gekennzeichnet, daß die Heizeinrichtung ein Peltierelement ist.To solve this problem is a thermostat of the type mentioned Art according to the invention, characterized in that the heating device is a Peltier element.
Dieses Peltierelement kann durch einfaches Vertauschen der Polung der an ihm angeschlossenen elektrischen Stromquelle von einer Heizeinrichtung in eine Kühleinrichtung umgewandelt werden, mit der dann der Metallblock und das in ihm befindliche Probengefäß gekühlt werden.This Peltier element can be changed by simply reversing the polarity the electrical power source connected to it from a heating device be converted into a cooling device with which then the metal block and the sample vessel in it are cooled will.
Die Erfindung und ihre Vorteile seien an Hand der Zeichnung näher dargestellt: The invention and its advantages are closer to the drawing shown:
Die Zeichnung zeigt im Längsschnitt einen Metallblock aus Aluminium, Kupfer oder Messing (2), der auf seiner Oberseite eine oder mehrere Sacklochbohrungen (3) aufweist, in der sich ein Reagenzglas (4) mit einer nicht näher zu bezeichnenden Probe befindet. Auf der Unterseite des Metallblocks (2) ist ein Peltierelement (5) mit gutem Wärmeübergang angebracht.The drawing shows in longitudinal section a metal block made of aluminum, copper or brass ( 2 ), which has on its top one or more blind holes ( 3 ) in which there is a test tube ( 4 ) with a sample that cannot be described in more detail. A Peltier element ( 5 ) with good heat transfer is attached to the underside of the metal block ( 2 ).
Den beiden elektrischen Anschlußleitungen (6 + 7) des Peltierelements (5) ist eine aus einer Batterie (8) bestehende Gleichstromquelle zugeordnet. Bei einer bestimmten Polung der an die Anschlußleitungen (6 + 7) angeschlossenen Batterie (8) wirkt die am Metallblock (2) anliegende Seite des Peltierelements (5) als Warmseite und beheizt so den Metallblock und das in ihm angeordnete Reagenzglas (4).A direct current source consisting of a battery ( 8 ) is assigned to the two electrical connecting lines ( 6 + 7 ) of the Peltier element ( 5 ). With a certain polarity of the battery ( 8 ) connected to the connecting lines ( 6 + 7 ), the side of the Peltier element ( 5 ) which is in contact with the metal block ( 2 ) acts as a warm side and thus heats the metal block and the test tube ( 4 ) arranged in it.
Durch Herstellen der entgegengesetzten Polung der an der Batterie
(8) angeschlossenen Anschlußleitung (6 + 7) wirkt die am Metallblock
(2) angebrachte Seite des Peltierelements (5) zu dessen Kaltseite,
so daß der Metallblock (2) und das in ihm befindliche Reagenzglas
(4) gekühlt werden.
Um die Kühl- oder Heizleistung des Thermostaten zu verstärken,
kann der Metallblock noch zusätzlich an den Seiten mit Peltierelementen
(11 + 12) versehen werden.
Zur Vermeidung der Wärme- oder Kälteabstrahlung ist der Metallblock
(2) an seiner Oberseite mit einem wärmeisolierenden Block
(9) mit den gleichen Sacklochbohrungen zur Aufnahme der Probengefäße
versehen. In der Regel besteht dieser Block (9) aus Polyurethan
oder Polystyrol.By producing the opposite polarity of the connecting line ( 6 + 7 ) connected to the battery ( 8 ), the side of the Peltier element ( 5 ) attached to the metal block ( 2 ) acts on its cold side, so that the metal block ( 2 ) and the test tube located in it ( 4 ) be cooled.
To increase the cooling or heating capacity of the thermostat, the metal block can also be provided with Peltier elements ( 11 + 12 ) on the sides.
To avoid heat or cold radiation, the metal block ( 2 ) is provided on its top with a heat-insulating block ( 9 ) with the same blind holes for receiving the sample vessels. As a rule, this block ( 9 ) consists of polyurethane or polystyrene.
Der in der Zeichnung dargestellte Thermostat weist selbstverständlich
noch weitere wärmeisolierende Umhüllungen und Ventilatoren auf
sowie eine elektronische Steuer- und Regeleinheit, die jedoch der
besseren Übersicht halber nicht dargestellt sind.
Mit entsprechenden Steuer- und Regelgeräten läßt sich der Thermostat
im Temperaturbereich von -60°C bis +60°C betreiben.The thermostat shown in the drawing of course has further heat-insulating coverings and fans and an electronic control and regulating unit, but these are not shown for the sake of clarity.
With the appropriate control and regulating devices, the thermostat can be operated in the temperature range from -60 ° C to + 60 ° C.
