Abstract

In absorption cooling systems, heat pumps or the like, it is usual to heat the so-called boiler of the system by means of an electric heating cartridge. This heating cartridge is mounted in a special metal sleeve or a cast part which is rigidly connected to the outer casing of the boiler. This arrangement is rather expensive and not infrequently leads to relatively high operating temperatures with correspondingly large thermal surface loads on the cartridge which shorten the life of the same. The aim was therefore to keep these high operating temperatures lower at the same time as simplifying the structure of the heating device. This aim is achieved in the heating device according to the invention in that the heating cartridge bears directly against the outer casing of the boiler and is covered by means of a hood-shaped reflection sheet which extends along the cartridge, is arranged at a given distance therefrom and is fastened together with the heating cartridge to the outer casing of the boiler. <IMAGE>

Description

Heizeinrichtung für den Kocher eines Absorberkühlsystems oder einer Wärmepumpe·Heating device for the cooker of an absorption cooling system or a heat pump

Die Erfindung betrifft eine elektrische Heizeinrichtung gemäß dem Oberbegriff des Patentanspruchs 1·The invention relates to an electrical heating device according to the preamble of claim 1

Bei bekannten Heizeinrichtungen dieser Art ist, wie beispielsweise die DE-PS 24 05 950 offenbart, die zur Beheizung dienende Heizpatrone in einer Metallhülse angeordnet, die ihrerseits mit dem Außenmantel des Kochers des Kühlsystems verschweißt ist. Außerdem ist es bereits bekannt, die Heizpatrone in einem Stranggußteil aus Aluminium einzusetzen, das wiederum am Außenmantel des Kochers angeklemmt ist·In known heating devices of this type, such as DE-PS 24 05 950 discloses which is used for heating The heating cartridge is arranged in a metal sleeve, which in turn is welded to the outer jacket of the cooker of the cooling system is. In addition, it is already known to use the heating cartridge in a continuously cast part made of aluminum that is in turn clamped to the outer jacket of the cooker

Diese Anordnungen dienen dem Zweck, die von der Heizpatrone erzeugte Wärme möglichst gleichmäßig auf den Kocher zu übertragen· These arrangements serve the purpose of transferring the heat generated by the heating cartridge as evenly as possible to the stove.

Die Erfahrung hat nun gezeigt, daß trotz des ziemlich auf wen-* digen Aufbaus der Heizeinrichtung verhältnismäßig hohe Betriebstemperaturen und damit hohe thermische Oberflächenbelastungen an der Heizpatrone auftreten können, vor allem dann, wenn die Wärmeübertragung durch meist nicht zu vermeidende Maßtoleranzen zwischen Heizpatrone und Hülse, bzw· dem Stranggußteil erschwert ist.Experience has now shown that despite the rather un- * Digen structure of the heating device relatively high operating temperatures and thus high thermal surface loads can occur on the heating cartridge, especially when the heat transfer occurs due to dimensional tolerances between the heating cartridge and the sleeve, or the Continuous casting is difficult.

Aufgabe der vorliegenden Erfindung ist es daher, bei gleichzeitiger Verminderung des erforderlichen technischen Aufwands, die Wärmeübertragung zwischen der Heizpatrone und demThe object of the present invention is therefore, at the same time Reduction of the necessary technical effort, the heat transfer between the heating cartridge and the

Kocher zu verbessern, um dadurch die thermische Belastung der Heizpatrone zu reduzieren und somit deren Lebensdauer zu erhöhen·Improve the cooker in order to reduce the thermal load to reduce the heating cartridge and thus to increase its service life

Biese Aufgabe wird durch die im Patentanspruch 1 gekennzeichneten Merkmale gelöst.This task is characterized by that in claim 1 Features solved.

Bei dieser neuartigen Heizeinrichtung entfällt eine besondere Metallhülse, bzw. der die Patrone aufnehmende Stranggußteil. Vielmehr wird die von der Heizpatrone erzeugte Wärme teilweise unmittelbar auf den Außenmantel des Kochers übertragen, wahrend ein anderer Teil dieser Wärme als Strahlungswärme vom Reflexionsblech zurückgeworfen und so ebenfalls auf den Außenmantel übertragen wird.With this new type of heating device, there is no need for a special metal sleeve or the continuously cast part holding the cartridge. Rather, the heat generated by the heating cartridge is partially directly applied to the outer jacket of the cooker transferred, while another part of this heat is called radiant heat is thrown back from the reflective plate and thus also transferred to the outer jacket.

Die Praxis hat bereits gezeigt, daß nicht nur die Fertigungskosten für die Heizeinrichtung sich erheblich vermindern lassen, sondern daß auch die Betriebstemperatur an der Heizpatrone wesentlich vermindert und damit die Lebensdauer derselben entsprechend erhöht werden können.1 Practice has already shown that not only can the production costs for the heating device be reduced considerably, but that the operating temperature at the heating cartridge can also be reduced considerably and the service life of the same can be increased accordingly. 1

Ein Ausführungsbeispiel der Erfindung ist nachstehend anhand der Zeichnung erläutert. Es zeigen Figur 1 eine teilweise im Schnitt dargestellte Seitenansicht der Heizeinrichtung undAn embodiment of the invention is explained below with reference to the drawing. Show it Figure 1 is a partially sectioned side view of the heating device and

denen die Heizpatrone 1 einschließlich des Reflexionsblechs. 2 am Außenmantel 5 eines Kochers 6 an sich bekannter Art befestigt sind. Der Kocher 6 weist zu diesem Zweck eine in seinen Außenmantel 5 eingeprägte Einne 9 auf, die im Querschnitt und in der Länge den Abmessungen der Heizpatrone 1 entspricht.which the heating cartridge 1 including the reflective plate. 2 attached to the outer casing 5 of a cooker 6 of a known type are. For this purpose, the cooker 6 has a recess 9 embossed in its outer casing 5, which in cross section and corresponds in length to the dimensions of the heating cartridge 1.

Das. über die ganze Länge der Heizpatrone 1 sich erstreckende Reflexionsblech 2 überdeckt haubenartig die Patrone. Um eine wirksame Reflektierung der von der Heizpatrone ausgehenden Infrarotstrahlung zu erzielen, hat das Reflexionsblech 2 einen gewissen, wenigstens 1 mm betragenden Abstand vom Mantel der Heizpatrone 1. Dieser Abstand wird durch mehrere, im Scheitelbereich des Reflexionsbleches 2 eingeprägte Sicken 7 od.dergl. erreicht, mit denen das Reflexionsblech dann auf der Patrone 1 aufliegt.That. over the entire length of the heating cartridge 1 extending Reflective plate 2 covers the cartridge like a hood. To ensure effective reflection of the heat emanating from the heating cartridge To achieve infrared radiation, the reflective plate 2 has a certain distance of at least 1 mm from the jacket of the heating cartridge 1. This distance is created by several beads 7 embossed in the apex area of the reflective plate 2 or the like. reached with which the reflective plate is then on the cartridge 1 rests.

Eine reLtere, feste Verbindung zwischen der Heizpatrone 1 und dem Reflexionsblech 2 ist durch eine Schweißstelle 8 gegeben, die an den Enden des Reflexionsblechs und der Heizpatrone vorgesehen ist.Damit bilden diese Teile auch eine die Montage der Heizeinrichtung erleichternde Baueinheit·A more recent, permanent connection between the heating cartridge 1 and the reflective plate 2 is given by a weld 8, which is at the ends of the reflective plate and the heating cartridge This means that these parts also form a unit that simplifies the assembly of the heating device.

Ergänzend wird hinzugefügt, daß die erfindungsgemäße Anordnung der Heizvorrichtung einschließlich des Kochers, ebenso, wie dies bei den bisher bekannten Ausführungsarten schon der Fall ist, mit einem Isoliermantel aus Stahlwolle od. dergl. umhüllt werden kann.In addition, it is added that the inventive arrangement of the heating device including the cooker, also, as is already the case with the previously known types of construction, with an insulating jacket made of steel wool or the like. can be wrapped.
