Heat exchanger

Abstract

A heat exchanger having a first flow channel, through which a first fluid can flow, and having a second flow channel, through which a second fluid can flow, whereby the first flow channel has a first section, a second section, and a redirection region, whereby the first section is in fluid communication with the second section via the redirection region and the second fluid can flow around the first section, the second section, and the redirection region, and whereby the first section and / or the second section of the first flow channel are each formed by a plurality of tubes.

Description

[0001]This nonprovisional application claims priority under 35 U.S.C. §119(a) to German Patent Application No. DE 10 2013 221 151.1, which was filed in Germany on Oct. 17, 2013, and which is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a heat exchanger having a first flow channel, through which a first fluid can flow, and having a second flow channel, through which a second fluid can flow, whereby the first flow channel has a first section, a second section, and a redirection region, whereby the first section is in fluid communication with the second section via the redirection region and the second fluid can flow around the first section, the second section, and the redirection region.[0004]2. Description of the Background Art[0005]So-called U-flow heat exchangers are used in many applications. These heat exchangers are characterized in that the fluid flowing through the heat exchanger flows in at one end ...

AI Technical Summary

Benefits of technology

The patent is about a heat exchanger that has a redirected flow direction, which makes it shorter than a traditional heat exchanger. This redirected flow is created through a redirection region where a second fluid flows. The use of tubes in the heat exchanger increases the heat transfer surface and allows for improved heat transfer between the fluids. The patent also describes a simple and cost-effective way to adapt the housing to the heat exchanger by using a cuboid structure and a deep-drawn cover. The flow section described in the patent demonstrates the benefits of the redirected flow, including increased efficiency and improved heat transfer. The tubes are mounted in the same end region, which increases stability and simplifies connections to fluid supply and drain lines.

Problems solved by technology

Heat exchangers with such a configuration are used, when the installation space no longer allows the use of heat exchangers with a conventional throughflow or other boundary conditions support their use.

It is a disadvantage, however, that only a smaller cross section per cooling section is available, which has a negative effect on the arising pressure loss.

It is particularly disadvantageous in the solutions in the prior art that the redirection region of the heat exchanger is either cooled not at all or cooled only by the air surrounding the heat exchanger.

Furthermore, the maximum heat transfer is often too low in the case of heat exchangers which provide flow around the flow channel including the redirection region.
