The effect of header shapes on the flow distribution in a manifold for electronic packaging applications

Abstract

The present paper investigates the effects of header shapes and the Reynolds number on the flow distribution in a parallel flow manifold to be used in a liquid cooling module for electronic packaging. The flow distribution in the manifold greatly depends on the header shape and the Reynolds number. Of the three different headers (i.e., rectangular, triangular, and trapezoidal), the triangular header produces the best flow distribution regardless of the Reynolds number.
