Problems solved by technology

[0002] Fluid flow leaving a heat exchanger typically exhibits a side-to-side temperature gradient across the outlet face of the heat exchanger, which can affect the accuracy of sensed temperature measurements downstream of the heat exchanger
Also, temperature gradients from one side of the outlet face of the heat exchanger to the other may prevent the splitting of the main fluid stream exiting the heat exchanger into two or more partial fluid streams having substantially the same temperature

Embodiment Construction

[0036] figure 1 Shown is the temperature distribution in a fluid stream leaving a heat exchanger installed on an aircraft. Depend on figure 1 It becomes apparent that the fluid flow exhibits a side-to-side temperature gradient at the outlet face of the heat exchanger, wherein when the fluid flow leaves a header of the heat exchanger having a first flow cross-section and enters a This temperature gradient is substantially maintained for tubes extending downstream and having a second flow cross-section smaller than the first flow cross-section of the heat exchanger header. In the fluid flow, the cold flow is mainly present in the lower part of the heat exchanger headers and in the lower part of the tubes extending downstream of the heat exchanger. In contrast to this, the warm current is mainly present in the heat exchanger headers and in the upper part of the tubes extending downstream of the heat exchanger. The central region of the fluid flow shows intermediate temperature...

Abstract

A homogenizing device (10) particularly adapted for homogenizing a temperature distribution in a fluid flow leaving a heat exchanger, a heat exchanger assembly and a method of homogenizing a temperature distribution in a fluid flow. The homogenizing device (10) comprises a body (12) having a fluid flow channel (14) extending through the body (12). The homogenization device (10) further comprises a flow control device (20) disposed in the fluid flow channel (14) and configured to flow through the fluid flow channel (14) ) induces a vortex (S) in the outer layer (32) of the fluid flow, while the flow characteristics of the inner layer (34) of the fluid flow remain substantially unaffected by the flow control device (20).

Description

technical field [0001] The invention relates to a homogenization device, a heat exchanger assembly comprising a homogenization device and a method of homogenizing a temperature distribution in a fluid flow. Background technique [0002] Fluid flow leaving a heat exchanger typically exhibits a side-to-side temperature gradient across the outlet face of the heat exchanger, which may affect the accuracy of sensed temperature measurements downstream of the heat exchanger. Furthermore, temperature gradients from one side of the outlet face of the heat exchanger to the other may prevent the splitting of the main fluid stream exiting the heat exchanger into two or more partial fluid streams having substantially the same temperature. Contents of the invention [0003] It is an object of the present invention to provide a homogenization device which allows rapid and reliable homogenization of the temperature distribution of the fluid flow leaving the heat exchanger from one side to...
