Description
Die Neuerung bezieht sich auf ein Kühlgerät für elektronische Bauelemente gemäß dem Oberbegriff des Schutzanspruches 1.The Innovation refers to a cooling unit for electronic components according to the preamble of the protection claim 1.
Ein
solches Kühlgerät ist aus
Weiter
ist dort vorgeschlagen, spezielle Wärmetauscherelemente
zu verwenden, wie sie in der
Diese bekannten Kühleinrichtungen arbeiten im Prinzip mit einem Luft/Luft-Wärmetausch, wobei davon ausgegangen wird, daß die Außenluft kälter ist als die Innenluft im Innenraum des Schaltschrankes. Bekanntlich hängt der Wärmeübergang an einem Wärmetauscher ganz wesentlich von der Temperaturdifferenz der miteinander im Wärmetausch stehenden Medien ab. Damit ist die Kühlleistung der bekannten Einrichtungen bei hohen Außentemperaturen nicht zufriedenstellend.These known cooling devices work in principle with a Air / air heat exchange, it being assumed that the Outside air is colder than the indoor air in the interior of the control cabinet. As you know, the heat transfer depends on a heat exchanger very much of the temperature difference the heat exchanging media from each other. In order to is the cooling capacity of the known devices at high Outdoor temperatures not satisfactory.
Im
Stand der Technik sind daher auch schon aktive Kühleinrichtungen
bekannt, die nach dem Prinzip eines Kühlschranks mit Kompressor
arbeiten (vgl.
Kühleinrichtungen
mit Peltierelementen sind auch in der
Die
Die
Peltierelemente sind heute als flache Plättchen mit Wärmeabgabe- und Wärmeaufnahmeseite erhältlich. Nachteilig ist naturgemäß ihr Verbrauch an elektrischer Energie und das Problem, daß der Wirkungsgrad bzw. die Kühlleistung temperaturabhängig sind und mit steigender Temperaturdifferenz zwischen Wärmeabgabeseite und Wärmeaufnahmeseite abnimmt.Peltier elements are today as flat plates with heat dissipation and heat absorption side available. adversely is naturally their consumption of electrical energy and the problem that the efficiency or the cooling capacity are temperature dependent and with increasing temperature difference between heat release side and heat absorption side decreases.
Aufgabe der Neuerung ist es, das Klimatisierungsgerät der eingangs genannten Art dahingehend zu verbessern, daß es in einem großen Temperaturbereich der Außentemperatur die Temperatur elektronischer Bauelemente gut innerhalb eines vorgegebenen Temperaturbereiches hält, eine hohe Leistungsdichte aufweist, möglichst kompakt ist und einen geringen Verbrauch elektrischer Energie hat.task the innovation is the air conditioning unit of the beginning mentioned type to improve that it in one large temperature range of the outside temperature the Temperature of electronic components well within a given Temperature range holds, has a high power density, as compact as possible and a low consumption of electrical Has energy.
Diese Aufgabe wird durch die im Schutzanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Neuerung sind den Unteransprüchen zu entnehmen.These The object is achieved by the features specified in the protection claim 1 solved. Advantageous embodiments and developments The innovation can be found in the dependent claims.
Das Grundprinzip der Neuerung besteht darin, das Kühlgerät als kompaktes Gerät mit Peltier-Elemente auszubilden, die beidseitig mit Wärmetauscherelementen versehen sind, wobei das Gerät zwei Lufteinlässe und zwei Luftauslässe aufweist, die mit zwei getrennten Strömungswegen verbunden sind, von denen einer an einer Seite des Peltier-Elementes und einer auf der anderen Seite des Peltier-Elementes verläuft. Die beiden Einlässe liegen vorzugsweise parallel in einer Ebene, wobei jedem Einlaß ein Ventilator zugeordnet ist, der die eintretende Luft von einem Einlaßraum über Leitbleche zu dem entsprechenden Strömungsweg an der Ober- oder Unterseite des Peltier-Elementes leitet.The The basic principle of the innovation is the cooling unit as a compact device with Peltier elements form the are provided on both sides with heat exchanger elements, wherein The device has two air inlets and two air outlets which are connected to two separate flow paths, one on one side of the Peltier element and one on the other side of the Peltier element runs. The two Inlets are preferably parallel in a plane, wherein Each inlet is associated with a fan, which enters the incoming Air from an inlet space via baffles to the corresponding flow path at the top or bottom of the Peltier element conducts.
Das Gerät ist vorzugsweise an Norm-Schaltschränke mit 19 Zoll Schienen angepaßt und hat eine Höhe von nur einer Höheneinheit, entsprechend 44,45 mm, eine Breite von 448 mm und eine Tiefe von 480 mm.The Device is preferably on standard control cabinets fitted with 19 inch rails and has a height of only one height unit, corresponding to 44.45 mm, one Width of 448 mm and a depth of 480 mm.
Das Gerät kann als reine Umwälzeinrichtung arbeiten, die kühle Außenluft durch Schlitze oder Öffnungen eines Schaltschrankes ansaugt und im Innenraum des Schaltschrankes umwälzt. Wird höhere Kühlleistung gefordert, so kann das Peltier-Element aktiv geschaltet und damit als aktiver Kühler arbeiten. Das Peltier-Element kann bei den oben beschriebenen Maßen bis zu 27 Einzelelemente enthalten, die je eine Leistung von 10 bis 15 Watt pro Einheit aufweisen, so daß eine Kühlleistung von 270 bis 405 Watt möglich ist.The device can work as a pure circulation device, which sucks cool outside air through slots or openings of a control cabinet and circulates in the interior of the control cabinet. If higher cooling capacity is required, the Peltier element can be activated and thus work as an active cooler. The Peltier element can be described at the above NEN contain up to 27 individual elements, each having a power of 10 to 15 watts per unit, so that a cooling capacity of 270 to 405 watts is possible.
Beim erst genannten Umwälzbetrieb kann auch einer der Ventilatoren abgeschaltet werden.At the The first mentioned circulation can also be one of the fans be switched off.
Zusammenfassend erhält man also ein Hybridkühlgerät mit geringer Einbauhöhe und hoher Leistungsdichte. Durch die beiden Betriebsarten läßt sich der Verbrauch an elektrischer Energie einsparen. Das Gerät läßt sich in verschiedenen Ausrichtungen in einen Schaltschrank einbauen, so daß die Kühlluft nach oben oder nach unten ausgeblasen wird.In summary So you get a hybrid cooling unit with low installation height and high power density. By the both modes can be consumed save electrical energy. The device leaves to install in different orientations in a control cabinet, so that the cooling air is up or down is blown out.
Im folgenden wird die Neuerung anhand eines Ausführungsbeispieles im Zusammenhang mit der Zeichnung ausführlicher erläutert. Es zeigt:in the The following will be the innovation based on an embodiment explained in more detail in connection with the drawing. It shows:
