High performance heat exchanger with calibrated bypass

A heat exchanger assembly includes a cooling plate having at least one outer heat transfer surface adapted to be in thermal contact with one or more heat generating substrates. A fluid flow path extends from the inlet port to the outlet port, and a plurality of cooling zones are spaced along the fluid flow path, each cooling zone including a heat transfer element, such as a corrugated fin in contact with an inner surface of the first plate wall. A manifold space is defined proximate the inlet and outlet ports and between adjacent cooling zones. One or more bypass flow passages are disposed between the upstream end and the downstream end of the at least one cooling zone to divert a portion of the heat transfer fluid flowing through the cooling zone. The amount of fluid bypassing the one or more cooling zones is calibrated to improve temperature uniformity of the heat generating substrate. 本发明涉及一种热交换器组件，其包括冷却板，该冷却板具有适合与一个或多个发热基板热接触的至少一个外传热表面。流体流动路径从入口端口到出口端口延伸，并且多个冷却区沿着流体流动路径间隔开，每个冷却区都包括传热元件，诸如与第一板壁的内表面接触的波纹式翅片
