AI Technical Summary
⚠Technical Problem
Existing plate heat exchangers face issues with high flow resistance and pressure drop due to high theta patterns causing turbulence, and cooling efficiency is compromised in applications like data center servers where components are closely arranged.
⚗Method used
A heat exchanger plate design with a quadrilateral shape and smooth corrugations featuring concentric transitions between ridges and valleys, minimizing flow disturbances and pressure drop by eliminating sharp direction changes.
🎯Benefits of technology
The design achieves low flow disturbance and pressure drop, ensuring efficient fluid distribution and cooling performance in heat exchangers, particularly suitable for data center server cooling applications.

Abstract
A heat exchanger plate has two opposite parallel primary sides and two opposite parallel secondary sides, and a longitudinal central axis parallel with the primary sides. The plate includes a heat exchanging area with ridges and valleys having a longitudinal extension defining an inclination relative to the longitudinal central axis, four portholes, with at least two located at a respective corner of the plate extending through the plate, a first set of ridges and valleys and a second set of ridges and valleys. The longitudinal extension of the first set of ridges / valleys defines a first angle relative to a first primary side and the longitudinal extension of the second set of ridges / valleys defines a second angle relative to a second primary side. An intersection between the first set of ridges / valleys and the second set of ridges / valleys defines a transition area comprising a curvature of ridges / valleys concentric with a porthole.
