Description

Thermoelektrische Kühleinrichtung Bei einer thermoelektrischen Kühleinrichtung, z. B. bei einem Kühlschrank, wird als Kühlelement eine Thermosäule verwendet, die in die Wand der Kühleinrichtung zwischen Kühlraum und Außenraum eingebaut ist. Die Länge der einzelnen Schenkel der Thermoelementsäule ist durch die Stärke dieser Wand festgelegt. Bei vorgegebener Kälteleistung ist der Materialbedarf für die thermoelektrischen Schenkel proportional zum Quadrat ihrer Länge und somit auch proportional zum Quadrat der Wandstärke. Diese ist nach unten hin durch die geforderte thermische Isolation begrenzt.Thermoelectric cooling device With a thermoelectric cooling device, z. B. in a refrigerator, a thermopile is used as the cooling element, the is built into the wall of the cooling device between the cooling space and the outside space. the The length of the individual legs of the thermocouple column is determined by the strength of this Wall set. With a given cooling capacity, the material requirements for the thermoelectric Legs proportional to the square of their length and therefore also proportional to the square the wall thickness. This is downwards due to the required thermal insulation limited.

Gegenstand der Erfindung ist eine thermoelektrische Kühleinrichtung, die nur einen verhältnismäßig geringen Aufwand an thermoelektrisch wirksamem Material erfordert. Dies ist dadurch erreicht, daß die Länge der Schenkel der einzelnen Elemente der Thermosäule kleiner bemessen ist als die Wandstärke zwischen Kühlraum und Außenraum an der Einbaustelle der Thermosäule. Die fehlenden Längen sind durch gut leitende Metallstücke überbrückt. Hierfür können z. B. Aluminium- oder Kupferstücke vorgesehen werden.The invention relates to a thermoelectric cooling device, which only requires a relatively small amount of thermoelectrically effective material requires. This is achieved by the length of the legs of the individual elements the thermopile is smaller than the wall thickness between the cold room and the outside space at the installation point of the thermopile. The missing lengths are due to well conductive ones Metal pieces bridged. For this, z. B. aluminum or copper pieces are provided will.

Zur weiteren Erläuterung des Erfindungsgegenstandes wird auf die Zeichnung hingewiesen; es zeigt Fig. 1 die Anordnung der Thermosäule in der Wand einer thermoelektrisdhen Kühleinrichtung in der bisherigen Bauweise, Fig. 2 die Anordnung der Thermosäule in der Wand einer therrnoelektrischen Kühleinrichtung gemäß der Erfindung.For further explanation of the subject matter of the invention, reference is made to the drawing pointed out; It shows Fig. 1 the arrangement of the thermopile in the wall of a thermoelectric Cooling device in the previous design, Fig. 2 the arrangement of the thermopile in the wall of a thermal-electric cooling device according to the invention.

Die thermoelektrisch wirksamen Teile sind in beiden Figuren jeweils mit 1, die Verbindungsstücke zwischen den Schenkeln, die z. B. aus Kupfer ausgeführt sein können, jeweils mit 2, und die Isolation ist mit 3 angegeben. Bei 4 sind jeweils Rippen angedeutet zur Vergrößerung der thermisch wirksamen Oberfläche der Verbindungsstücke. Während in Fig. 1 die thermoelektrisch wirksamen Schenkel jeweils die Länge der Wanddicke besitzen, sind sie in der Anordnung nach Fig.2 wesentlich kürzer gehalten. Die Verbindung zwischen den thermoelektrisch wirksamen Teilen 1 und den Verbindungsstücken 2 ist durch gut leitende Zwischenstücke, die mit 5 bezeichnet sind, hergestellt; sie können z. B. aus Aluminium oder Kupfer ausgeführt sein. Hierdurch ergibt sich bei gleicher thermoelektrischer Wirkung, also bei gleicher Kälteleistung, ein wesentlich kleinerer Aufwand an hochwertigem thermoelektriseh wirksamem Material und damit eine wesentliche Verbilligung der Einrichtung. Da der Materialaufwand quadratisch von der Länge der Schenkel abhängt, ergibt z. B. eine Verkürzung der Thermoelementschenkel auf die Hälfte eine Ersparnis an thermoelektrisch wirksamem Material von 75'%.The thermoelectrically effective parts are in both figures with 1, the connecting pieces between the legs, the z. B. made of copper can be, each with 2, and the insulation is indicated with 3. At 4 are each Ribs indicated to enlarge the thermally effective surface of the connecting pieces. While in Fig. 1, the thermoelectrically effective legs each the length of the Have wall thickness, they are kept much shorter in the arrangement according to Figure 2. The connection between the thermoelectrically active parts 1 and the connecting pieces 2 is made by highly conductive spacers, which are designated with 5; you can z. B. made of aluminum or copper. This results in with the same thermoelectric effect, i.e. with the same cooling capacity, an essential less expenditure on high-quality thermoelectrically effective material and thus a substantial reduction in the price of the facility. Since the cost of materials is quadratic depends on the length of the legs, z. B. a shortening of the thermocouple legs a saving of 75% in thermoelectrically effective material by half.
