What heat exchangers are suitable for AI liquid‑cooled CDU primary cooling loops?

For large‑scale hyperscale AI data‑center CDU main cooling loops, Shenshi plate‑and‑shell heat exchanger is the primary recommendation. It supports high flow rate, low pressure drop and cleanable structure, comparable with API SIGMA and Alfa Laval plate‑and‑shell products.Shell‑and‑tube is available as a low‑cost alternative, yet bulky and lower heat‑transfer efficiency. PCHE is not recommended for large‑flow primary CDU cooling due to higher pressure drop. PFHE is limited to gas‑side heat transfer only.
