The thermal performance of heat pipes with localized heat input

International Journal of Heat and Mass Transfer, 1989
The performance of heat pipes with localized heat input including the effects of axial and circumferential heat conduction under high and low working temperatures is investigated. The numerical results show that when heat pipes are spot heated, the peak temperature of the wall is greatly reduced and the surface can be protected from being burned out by

Transient Analysis of Nonuniform Heat Input Propagation Through a Heat Sink Base

Journal of Electronic Packaging, 2016
For thermal management architectures wherein the heat sink is embedded close to a dynamic heat source, nonuniformities may propagate through the heat sink base to the coolant. Available transient models predict the effective heat spreading resistance to calculate chip temperature rise, or simplify to a representative axisymmetric geometry.
