Abstract

The exchanger (1) has a heat transmitting block (2) with pipes (3, 4, 6, 7), where medium flows through the pipes. The pipes (3, 4) discharge into a collecting chamber (11) and the pipes (6, 7) discharge into a collecting area (12) of a collecting device (10). The pipes are overlappingly arranged in two rows (5, 8) such that the pipes are perpendicular to flow direction of the pipes. The pipes (6, 7) are extended up to another collecting chamber over the chamber (11), where the latter chamber is arranged at preset distance to the chamber (11) in the flow direction of the pipes.

In Figur 1 ist ein Wärmeübertrager 1 in vier verschiedenen Ansichten dargestellt. Der Wärmeübertrager 1 umfasst einen Wärmeübertragungsblock 2 mit ersten Rohren 3, 4, die in einer ersten Reihe 5 angeordnet sind. Die ersten Rohre 3, 4 dienen zum Durchführen eines Mediums, zum Beispiel Wasser, und sind parallel zueinander in einer Richtung x angeordnet. Die Richtung x wird auch als Durchströmungsrichtung der Rohre bezeichnet. Die ersten Rohre 3, 4 sind in der ersten Reihe 5 in einer Richtung y nebeneinander angeordnet. Senkrecht zu den Richtungen x, y erstreckt sich eine Richtung z, in welcher die Rohre 3, 4 von einem weiteren Medium, zum Beispiel Luft, umströmt werden. Die Richtung z wird auch als Umstromungsrichtung der Rohre 3, 4 bezeichnet. Zweite Rohre 6, 7 sind in einer zweiten Reihe 8 angeordnet, die sich in y-Richtung erstreckt und in z-Richtung von der ersten Reihe 5 beabstandet ist. Vorzugsweise ist jedem ersten Rohr 3, 4 ein zweites Rohr 6, 7 zugeordnet.In FIG. 1 a heat exchanger 1 is shown in four different views. The heat exchanger 1 comprises a heat transfer block 2 with first tubes 3, 4, which are arranged in a first row 5. The first tubes 3, 4 serve to convey a medium, for example water, and are arranged parallel to one another in a direction x. The direction x is also referred to as the flow direction of the tubes. The first tubes 3, 4 are arranged in the first row 5 in a direction y next to each other. Perpendicular to the directions x, y extends a direction z, in which the tubes 3, 4 are surrounded by another medium, for example air. The direction z is also referred to as Umstromungsrichtung of the tubes 3, 4. Second tubes 6, 7 are arranged in a second row 8, which extends in the y-direction and is spaced in the z-direction from the first row 5. Preferably, each first tube 3, 4, a second tube 6, 7 assigned.

Die ersten Rohre 3, 4 und die zweiten Rohre 6, 7 münden mit einem ihrer Enden in eine Sammeleinrichtung 10, die einen ersten Sammelkasten 11 und einen zweiten Sammelkasten 12 umfasst. Die beiden Sammelkästen 11, 12 haben im Wesentlichen die Gestalt von Sammelrohren, von denen an einem Ende jeweils ein Anschlussstutzen 13, 14 abgewinkelt ist. Die Anschlussstutzen 13, 14 sind jeweils einstückig mit dem zugehörigen Sammelkasten 11, 12 verbunden.The first tubes 3, 4 and the second tubes 6, 7 open at one end into a collecting device 10, which comprises a first collecting box 11 and a second collecting box 12.

Gemäß einem wesentlichen Aspekt der Erfindung sind die zweiten Rohre 6, 7 in x-Richtung, das heißt in Durchströmungsrichtung der Rohre, über den ersten Sammelkasten 11 hinaus verlängert. Der zweite Sammelkasten 12 erstreckt sich parallel zu dem ersten Sammelkasten 11. Allerdings ist der zweite Sammelkasten 12 in der positiven x-Richtung und in der negativen z-Richtung gegenüber dem ersten Sammelkasten 11 versetzt angeordnet. Dadurch ist es möglich, dass die beiden Anschlussstutzen 13, 14 in x-Richtung übereinander angeordnet sind.According to an essential aspect of the invention, the second tubes 6, 7 in the x-direction, that is, in the flow direction of the tubes, extended beyond the first collection box 11 addition.
