Device For Heat Exchange And Method For Producing One Such Device

Abstract

The invention relates to a device for heat exchange, said device comprising a flow device and a collection and/or distribution device connected to the flow device at a connection point. The flow device has a pre-determined length and a flat tubular cross-section, and a fluid under a high pressure, for example an operating pressure of approximately 125 bar, flows through the same. Said flow device has a linear course over the entire length thereof, along a longitudinal axis thereof. The long side of the flat tubular cross-section of the flow device is approximately between 5 mm and 6.1 mm, and is at an angle of approximately 90°, at the connection point, in relation to a main direction of extension of the collection and/or distribution device.
