Abstract

Die Erfindung betrifft eine Vorrichtung zur Steigerung der Waermeabgabe von Heizkoerpern mit einem Schichtkoerper und einer Isolierschicht, wobei der Schichtkoerper mindestens aus einer dem Heizkoerper zugewandten Absorberschicht und einer der Wand zugewandten Isolierschicht besteht und in einem Abstand vom Heizkoerper direkt oder indirekt an der Wand befestigt ist. Durch die erfindungsgemaesse Vorrichtung wird die Schaltungsenergie durch die Absorberschicht aufgenommen und dadurch eine Erhoehung der Konvektion zwischen Heizkoerper und Wand erreicht, was zu einer Steigerung der Leistung fuehrt. Fig. 1The invention relates to a device for increasing the heat emission of Heizkoerpern with a layer body and an insulating layer, wherein the Schichtkoerper at least one of the Heizkoerper facing absorber layer and an insulating wall facing the wall and is fixed at a distance from the radiator directly or indirectly on the wall. By means of the device according to the invention, the circuit energy is absorbed by the absorber layer, thereby achieving an increase in the convection between the heater and the wall, which leads to an increase in power.

embodiment

Die Erfindung soll nachstehend an zwei Ausführungsbeispielen näher beschrieben werden. Dabei zeigtThe invention will be described below with reference to two embodiments. It shows

Fig. 1: Vorrichtung zur Steigerung der Wärmeabgabe ohne Wärmeleitschicht, Fig. 2: Vorrichtung zur Steigerung der Wärmeabgabe mit Wärmeleitschicht.Fig. 1: Apparatus for increasing the heat dissipation without Wärmeleitschicht, Fig. 2: Apparatus for increasing the heat transfer with Wärmeleitschicht.

In Fig. 1 ist dem Heizkörper 1 im Abstand A ein Schichtkörper, der aus einer Absorberschicht 2 mit einer Isolierschicht 3 besteht, zugeordnet, wobei dieser direkt an die Wand 4 durch Kleber befestigt ist. Die Absorberschicht 2 besteht aus einer dunklen dünnen Papierschicht und die Isolierschicht 3 aus einer viskosen Wärmedämmatte. In Fig. 2 ist dem Heizkörper 1 im Abstand A ein Schichtkörper, der aus einer Absorberschicht 2, einer Metallplatte 5 und einer Isolierschicht 3 besteht, wobei dieser in eine in der Wand 4 verankerte Haltevorrichtung 6 gehängt und durch einen Abstandhalter 7 indirekt an der Wand 4 befestigt ist, zugeordnet. Die Absorberschicht 2 ist ein Farbanstrich mit hohem Absorptionskoeffizient. Die Metallplatte 5 fungiert zugleich als Stabilisierungselement und als Schicht mit einer hohen Wärmeleitfähigkeit bzw. Wärmekapazität.In Fig. 1, the radiator 1 at a distance A is a composite body, which consists of an absorber layer 2 with an insulating layer 3, assigned, which is attached directly to the wall 4 by adhesive. The absorber layer 2 consists of a dark thin paper layer and the insulating layer 3 of a viscous thermal insulation mat. In Fig. 2, the radiator 1 at a distance A is a layered body consisting of an absorber layer 2, a metal plate 5 and an insulating layer 3, which hanged in a anchored in the wall 4 holding device 6 and by a spacer 7 indirectly to the wall 4 is attached, assigned. The absorber layer 2 is a paint with a high absorption coefficient. The metal plate 5 also acts as a stabilizing element and as a layer with a high thermal conductivity or heat capacity.

In beiden Fällen wird durch die Absorberschicht 2 die Strahlungswärme aufgenommen, wobei sich die Oberfläche aufheizt. Die zwischen Heizkörper 1 und Schichtkörper aufsteigende Luft wird konvektiv beidseitig erwärmt, wodurch sie sich stärker aufheizt als bei konventionellen Ausführungen. Dies führt zu einem erhöhten thermodynamischen Auftrieb, wobei in gleicher Zeit mehr Raumluft am Heizkörper vorbeiströmt, diese besser gekühlt und damit die Rücklauftemperatur des Heizmediums weiter abgesenkt wird, was wiederum zu einer Erhöhung der Wirtschaftlichkeit der Heizungsanlage führt.In both cases, the radiant heat is absorbed by the absorber layer 2, wherein the surface heats up. The ascending between radiator 1 and laminate air is convectively heated on both sides, causing it to heat up more than in conventional designs. This leads to an increased thermodynamic buoyancy, wherein in the same time more room air flows past the radiator, this better cooled and thus the return temperature of the heating medium is further lowered, which in turn leads to an increase in the efficiency of the heating system.

Field of application of the invention

The invention relates to a device for increasing the heat output of radiators with a laminated body and an insulating layer.

Characteristic of the known state of the art

The heat output of a radiator is in addition to the radiation mainly by the convection, ie the heat transfer to the air flowing past the surface, achieved.

There are quite generally known devices for increasing the heat output of radiators, where by incorporation and profiling an increase in surface area of the heat-emitting elements of a radiator should be achieved. Likewise, devices are known in which the heat losses are reduced by heating the outer wall by reflectors. There is known a heat reflector for radiators (DE 2639195), which consists of a stiff aluminum-coated cardboard. The shiny aluminum layer facing the radiator reflects a large part of the heat radiation back and thereby reduces increased heating of the room outer wall. There is also a device for suppressing the heat loss of a heat source with a support plate and the radiator facing reflector layer (DE 2820319) known in which by using the Dewar vessel (thermos) ago known principle for the prevention of heat loss of a heating source used becomes. All these known devices have the disadvantage that they reflect the heat radiation but do not increase the heat output of the radiator. The air flowing past the reflector layers is not or only slightly heated by them.

Object of the invention

The aim of the invention is to make heating systems more economical by the heat dissipation performance of the radiator is increased.

Explanation of the essence of the invention

The invention has for its object to provide a device in which the heating of the room outer wall largely avoided and at the same time the heat output of the radiator is increased by increasing the convection. According to the invention, the object is achieved in that the laminated body consists of at least one of the radiator absorber layer facing and one of the wall facing insulating layer and is fixed at a distance A from the radiator directly or indirectly to the wall, wherein the distance Α-a minimum for the realization of a represents free convection. It is further according to the invention that between the absorber layer and the insulating layer, a layer with high thermal conductivity and high heat capacity is arranged and that the absorber layer consists of a perforated paper layer or a paint.
