Optimal Finned Heat Sinks
In a multi-board computer system, the volume allocated for heat removal is often a significant fraction of the total system volume. Cooling requirements can thus impact performance, reliability, cost, acoustic noise, and floorspace. This work addresses the volume costs or space requirements for removing heat with optimally designed finned heat sinks. Simple formulas applicable to both gas and l...
متن کاملExperimental and Numerical Study of Transient Electronic Chip Cooling by Liquid Flow in Microchannel Heat Sinks
Cooling of electronic chips has become a critical aspect in the development of electronic devices. Overheating may cause the malfunction or damage of electronics. The time needed for heat removal is particularly important in a wide range of electronic systems, such as switching circuits. Thus, it is important to characterize the transient behavior of the system and determine the response. Most ...
متن کاملNumerical Studies on the Performance of Finned-Tube Heat Exchanger
Finned-tube heat exchangers are predominantly used in space conditioning systems, as well as other applications requiring heat exchange between two fluids. The design of finned-tube heat exchangers requires the selection of over a dozen design parameters by the designer such as tube pitch, tube diameter, tube thickness, etc... Finned-tube heat exchangers are common devices; however, their perfo...

Numerical Optimization of Trapezoidal Microchannel Heat Sinks
This study presents the numerical simulation of three-dimensional incompressible steady and laminar fluid flow and conjugate heat transfer of a trapezoidal microchannel heat sink using water as a cooling fluid in a silicon substrate. Navier-Stokes equations with conjugate energy equation are discretized by finite-volume method. We perform numerical computations for a range of 50 Re 600, 0.05W ...
