Rectangular Channel Cold Plate Heat Transfer Characteristics Of Hollow-core

This paper concentrates on the study of heat transfer characteristics of rectangular channels Cold-Plate used in electronic devices , The experimental way and three-dimensional numerical simulation method are applied which is just carried out in our country. Two test pieces with satin surface and rib surface were designed under conditions of different distribution of heat flow density and different air flux. In the following chapters, a set of three-dimensional mathematical models involving the heat transfer of the coolant turbulent flow and heat conduction coupling, which is applicable in engineering, was established according to currency N-S control equation, the SIMPLER algorithm in an unstaggered grid system, SMART scheme and k- e turbulence model are used in the flowfield ; The method of whole-field dispersed and solved are appled in the temperature field. The methods of SIP and multigride accelerate the convergence. At last the calculated results were compared with the experimental values, which shows that the mathematical model and theoretical computation in this paper were rather effective.
