Heat exchange device

Abstract

The invention relates to a heat exchange device characterized by a particular configuration of the liquid inlet or outlet manifold in which it incorporates a baffle formed from the shell itself. This configuration allows not only suitably orient the inflow into regions of the tube bundle of the exchanger where convection must be more intense, but also allows generating a flow suitable for reaching all the regions having a higher convective heat transfer requirement. Configuring a baffle from the shell prevents incorporating and manufacturing specific additional parts, as well as the additional operations required for their configuration and attachment to the heat exchanger.

AI Technical Summary

Benefits of technology

The patent text describes two configurations for a tube bundle closure. In the second configuration, the tubes are stacked with expanded ends to provide passage channels for a second fluid and maximize the area for heat transfer. This design eliminates the need for baffles and reduces thermal fatigue, increasing the service life of the device. Additionally, this design eliminates the need for specific parts that must be attached to the manifold.

Problems solved by technology

Solutions of this type have two drawbacks, the first being the use of additional parts that must be manufactured, for example, by die-cutting and stamping, and subsequently attached by welding.

This second attachment is complex since the baffle has a warped configuration, is located inside a tube and therefore in a somewhat inaccessible area, and requires specific equipment that increases manufacturing costs.

Although these jets acquire a higher velocity, they do not have a uniform configuration that can cover the entire inlet section adjacent to the end of the tube bundle where the hot gas enters and cause substantial pressure drops.
