Flow channel for a heat exchanger and heat exchanger with the same

Abstract

The invention relates to a flow channel of a heat exchanger with two parallel heat transfer areas (F1, F2) that are arranged at a distance corresponding to a channel height H. Each heat transfer area (F1, F2) is provided with a structure that is formed by a plurality of structural elements which are placed next to each other in rows running perpendicular to the direction of flow P and extend into the flow channel. Each structural element has a width B, a length L, a height h, a flow-off angle alpha, and an overlap while being provided with a longitudinal axis.

Description

technical field

[0001] The invention relates to a flow channel of a heat exchanger through which a medium can flow in one flow direction. Furthermore, the invention also relates to a heat exchanger with the aforementioned flow channel. Background technique

[0002] The flow channels in the heat exchanger are passed through by a first medium, such as exhaust gas or liquid coolant, and separate the first medium from the second medium, and the first medium transfers heat to the second medium. Such a flow channel can be a tube with a circular cross section, a rectangular tube, a flat tube or also a double-piece formed by connecting two plates or plates at the edges. In most cases, the media in the heat exchange are different, for example, the hot exhaust gas containing carbon black particles flows in the tube, while the exhaust gas tube is circulated by a liquid coolant on the outside, so that in the tube Different heat transfer occurs on the inside and outside. Therefore, it...
