Abstract (en)
[origin: WO2021144671A1] A baffle system and heat-exchange apparatus generally comprising a plurality of baffles and a plurality of tubes, wherein the plurality of baffles define at least one permeable support region and at least one barrier region. The at least one permeable support region can permit shell-side fluid to pass through the baffles and flow along the lengths of the tubes generally unimpeded and thereby prevent excessive shell-side pressure drop. The at least one barrier region can create turbulence in the flow of the shell-side fluid surrounding the plurality of tubes and prevent stratification. The combination of the permeable support region and barrier region within the baffle system or heat-exchange apparatus can yield a swirl flow that can reduce excessive shell-side pressure drop, reduce stratification in the flow of the shell-side fluid, and promote the efficiency of heat transfer between tube-side fluid and shell-side fluid.
