Abstract

A plurality of bismuth telluride rods (5) is placed on a ceramic plate, and electrically connected in a series (7). The current flowing through cools the lower side of said rods (5) and heats the upper side. The lower ceramic plate (6), and the upper ceramic plate (3), are electrically non-conductive but form a cold or warm parallel mounting. Temperature differences of approximately 150 EC and more, according to structure e.g. 5-24 volts, arise between the upper and lower side when operation with direct current voltage occurs and the only insulation is the air gap between the rods (5). If the air gap is filled with a casting material, circulation is impeded and the refrigerating capacity is reduced. A temperature bulkhead (4) made of an electrically non-conducting material, which reflects infrared heat and which is temperature resistant, acts as a mask between the rods (5). It does not impede circulation but enables infrared warmth to be reduced, thereby reducing the equalization procedure, whereby refrigerating capacity is improved without consuming any more electric power.

(Beschreibung)(Description)
Technisches Gebiet:Technical field:
High Tee Peltier, dadurch gekennzeichnet daß eine zusätzlicheHigh tea Peltier, characterized in that an additional
Temperaturabschottung zwischen zwei Keramikscheiben eingefügt wird.Temperature insulation is inserted between two ceramic discs.
Zwischen den beiden Keramikscheiben besteht ein Temperaturunterschied von ca. 120 °C.There is a temperature difference of approx. 120 ° C between the two ceramic discs.
Der derzeitige maximale Minusbereich liegt bei ca. 13 ° C.The current maximum minus range is approx. 13 ° C.
Was durch die Wärmeeinstrahlung in Grenzen gehalten wird.What is limited by the heat radiation.
Durch das Einbauen einer ca. 1 mm starken Lochrasterscheibe, aus einem elektrisch nicht leitendem und infrarot abweisendem Material, kann die von der warmen Keramikscheibe ausgehende Infrarotstrahlung die kalte Keramikscheibe nicht direckt beeinflussen.By installing an approximately 1 mm thick perforated grid disc made of an electrically non-conductive and infrared-repellent material, the infrared radiation emanating from the warm ceramic disc cannot directly influence the cold ceramic disc.
Die Lochrasterscheibe muß zentriert in der Mitte des Luftspalts sitzen. Somit verhindern wir die Egalisation und steigern die Efecktievität.The perforated screen must be centered in the middle of the air gap. In this way, we prevent equalization and increase the efectiveness.
Die dadurch anfallende gesteigerte Abwärme muß mittels Hochleistungskühl- kδrper, in Verbindung mit Lüftern abgeführt werden.The resulting increased waste heat must be dissipated using a high-performance heat sink in conjunction with fans.
Die gesteigerte Kälteleistung ist unser Gewinn !The increased cooling capacity is our gain!
Stand der Technik:State of the art:
Temperaturabschottungen in Peltierelementen gibt es unseres Wissens nicht auf dem Mark! Darstellung der Erfindung:As far as we know, there are no temperature seals in Peltier elements on the market! Presentation of the invention:
High Tee Peltier, dadurch gekennzeichnet daß, durch einbauen einer Lochrasterscheibe1 zentriert in der Mitte des Luftspalts eines herkömmlichen seriell hergestelltenHigh Tee Peltier, characterized in that, by installing a perforated grid disc 1 centered in the middle of the air gap of a conventional serially manufactured
Peltierelements die Infrarotstrahlung abgeschirmt wird.Peltier element the infrared radiation is shielded.
Die Egalisierung zwischen warm und kalt wird stark verhindert.The leveling between warm and cold is strongly prevented.
Damit wird die eingesetzte Leistung optimiert.This optimizes the performance used.
So wird aus einem Peltierelement, ein High Tee Peltierelement !How a Peltier element becomes a high tea Peltier element!
Problem: Die Kühlleistung verbessern, ohne mehr Energie einzusetzen!Problem: Improve the cooling performance without using more energy!
Lösung: Ein serienmäßig hergestelltes Peltierelement, in unterschiedlichen Größen und Leistungen besteht aus zwei Keramikplatten, zwischen denen p- und n dotierte Wismuttelluridstäbchen elektrisch in Reihe und thermisch parallel geschaltet sind.Solution: A standard Peltier element, in different sizes and capacities, consists of two ceramic plates, between which p- and n-doped bismuth telluride rods are electrically connected in series and thermally in parallel.
Dieser Halbleiter hat bessere α Werte.This semiconductor has better α values.
( α = die Thermokraft, gemessen in Volt / Grad), als Isolatoren oder Metalle.(α = the thermal force, measured in volts / degrees), as insulators or metals.
Die Keramikplatten sind elektrisch gute Isolatoren und thermisch gute Leiter, die hohem mechanischemThe ceramic plates are good electrical insulators and good thermal conductors, the high mechanical

Das Peltierelement ist kein Kälte produzierendes Aggregat, sondern nur eine elektrische Wärmepumpe. Da eine Wärmepumpe Wärme transportiert, inuß diese an der anderen Seite durch kontaktieren eines Kühlkörpers abgeführt werden.The Peltier element is not a cold-producing unit, but only an electric heat pump. Since a heat pump transports heat, it must be dissipated on the other side by contacting a heat sink.
Andernfalls würde sich die warme Seite soweit aufheizen, bis das Peltierelement nicht mehr als kühlendes Element arbeitet, sondern die kalte Seite erwärmt wird. Wesentliche Verbesserung:Otherwise, the warm side would heat up until the Peltier element no longer works as a cooling element, but rather the cold side is heated. Significant improvement:
Leistungsverbesserung durch verhindern der , Infrarotwärmebestrahlung an der kalten Seite. Die Wismuttelluridstäbchen (Kappes) sitzen freistehend mit längs- und querabstand zwischen zwei Keramikplatten. Der Plattenabstand liegt je nach Bauart und Hersteller bei ca.2,8 - 3,2 mm.Improved performance by preventing infrared heat radiation on the cold side. The bismuth telluride sticks (caps) sit free-standing with longitudinal and transverse spacing between two ceramic plates. Depending on the type and manufacturer, the plate spacing is approx. 2.8 - 3.2 mm.
Die Keramikplatten sind während des Betriebs mit einem Themperaturunterschied bis ca. 130 / 150 ° C (Kelvin) behaftet. (Differenz zwischen warmer und kalter Seite). Der Zwischenraum zwischen den in Reihe geschalteten Kappes ist Luft.The ceramic plates have a temperature difference of up to approx. 130/150 ° C (Kelvin) during operation. (Difference between warm and cold side). The space between the caps connected in series is air.
Diese Luft dient als Isolierung und verhindert eine gegenseitige Berührung der einzelnen Kappes, was zu einem Kurzschluß führen würde.This air serves as insulation and prevents the individual caps from touching one another, which would lead to a short circuit.
Um eine Kälteleistung zu erzielen muß an der Oberfläche der Keramikplatte die anfallende Wärme abgeführt werden.In order to achieve a cooling capacity, the heat must be dissipated on the surface of the ceramic plate.
Durch das Einbauen unserer Temperaturabschottung wird die Egalisierung stark verhindert. Die Kälteleistung wird trastisch gesteigert! Equalization is strongly prevented by installing our temperature insulation. The cooling capacity is increased dramatically!
