Abstract

The cooling or heating elements are made from two flat thin plates. The element is made by a relatively simple method and has maximum surface area. The two flat plates (1, 2) are stacked and joined as required positions (5). The edges of plates are also joined. A fluid is pumped into space between the plates and these are bulged outwards. The fluid is drained after deformation. The bulging is partially resisted for ensuring required shape. The bulging can be restricted to one plate only. The plate arrangement is expanded to yield a quilted blanket form.

Nachstehend wird die Erfindung in Verbindung mit der Zeichnung anhand von Ausführungabeispielen erläutert. Es zeigen: Fig. 1 eine Aufsicht auf einen Heiz- bzw. Kühlkörper gemäß der Erfindung, Fig. 2 einen Schnitt durch den Körper nach Fig. 1 längs der Linie I-I, Fig. 3 einen Schnitt entsprechend Fig. 3 nach erfolgtem Aufblasen des Körpers, Fig. 4 eine Variante nach Fig. 3 in vergrößertem Maßstab und Fig. 5 eine weitere Ausführungsform der Ausgestaltung nach Fig. 4.The invention is explained below in conjunction with the drawing explained by execution examples. They show: FIG. 1 a plan view of a heating or heat sink according to the invention, FIG. 2 shows a section through the body 1 along the line I-I, FIG. 3 shows a section corresponding to FIG. 3 after the completion Inflation of the body, FIG. 4 shows a variant of FIG. 3 on an enlarged scale and FIG. 5 shows a further embodiment of the configuration according to FIG. 4.

Zwei ebene Platten 1 und 2 aus Stahlblech, Kunststoff oder dergleichen Material werden mit Zuleitung 3 und Ableitung 4, die beide mit dem zwischen den beiden Platten 1, 2 gebildeten Raum in Verbindung stehen, aufeinandergelegt und an einer Vielzahl von Stellen 5, die z. B. im Abstand von 5 cm voneinander ausgebildet und symmetrisch und gleichmäßig über die Platten 1, 2 verteilt sind, verbunden. Dieses Verbinden kann durch Punktschweißen, Rollschweißen, Verkleben oder dergleichen erfolgen. Die Platten 1 und 2 werden am gesamten Umfang 6 miteinander dicht verbunden, z. B. verschweißt, so daß der Zwischenraum nach außen dicht ist, und es wird über dem Einlaß (bei geschlossenem Auslaß) ein Druckmedium (z. B. Luft, Wasser, öl oder dergl.) unter einem ausreichend hohen Druck eingeführt,- daß sich die freien Teilwandungen der beiden Platten 1 und 2 zwischen der Verbindungsstellen 5 voneinander weg ausbauchen (bei 7). Dieses Ausbauchen kann unbehindert oder behindert erfolgen. Im unbehinderten Zustand wölben sich die einzelnen Teilflächen von jeweils 4 zugeordneten Feststellen aus in natürlicher Weise steppdeckenförmig nach Art von Gewölben. Im behinderten Zustand wird diese natürliche Ausbauchung dadurch unterbunden, daß die Ausbauchung begrenzt wird. Dies geschieht z.B. in der Weise, daß nach Fig. 4 im Abstand zu beiden Seiten der Platten 1 und 2 massive Platten bzw. Wände 12, 13 oder dergl. angeordnet sind, die eine Ausbauchung im Scheitelbereich 14, 15 begrenzen, und daß dieser Scheitelbereich eben ausgebildet wird.Two flat plates 1 and 2 made of sheet steel, plastic or the like Material are supplied with supply line 3 and discharge line 4, both of which are connected to the between the two panels 1, 2 formed space are connected, placed on top of each other and at a plurality of points 5, which, for. B. formed at a distance of 5 cm from each other and symmetrically and evenly distributed over the plates 1, 2, connected. This joining can be done by spot welding, roll welding, gluing or the like take place. The plates 1 and 2 are tightly connected to one another over the entire circumference 6, z. B. welded so that the space is tight to the outside, and it is over the inlet (with the outlet closed) a pressure medium (e.g. air, water, oil or the like.) Introduced under a sufficiently high pressure, - that the free partial walls the two plates 1 and 2 between the connection points 5 bulge away from each other (at 7). This bulging can be unhindered or disabled. In the unhindered state, the individual sub-areas of 4 assigned to each bulge Detecting from naturally quilt-shaped like vaults. in the disabled condition, this natural bulge is prevented by the fact that the Bulge is limited. This is done, for example, in such a way that according to Fig. 4 in Distance on both sides of the plates 1 and 2 massive plates or walls 12, 13 or The like. Are arranged that limit a bulge in the apex area 14, 15, and that this apex area is made flat.
