Heat Generation and Dissipation

2013
The adverse impact of temperature on device/material reliability has been emphasized often in this book. The degradation rate for most devices/materials tends to accelerate exponentially with increasing temperature. Therefore, for reliability reasons, lower temperature device operation is usually preferred.

The dissipation of frictional heat

Applied Scientific Research, 1955
The load-carrying or power-transmitting capacity of many machine parts is decisively affected by the maximum temperatures that occur in the source of frictional heat. In controlling these temperatures, and thus the performance limits concerned, two types of dissipation of frictional heat, which act in series, have to be accounted for: 1.

HEAT DISSIPATION OF PRIMARY AND SECONDARY BATTERIES

Unmanned Spacecraft Meeting 1965, 1965
Calorimetric data are given for the heat generated in a 30-Ah nickel-cadmium battery and a 360-Ah silver--zinc battery. Equations are also given to calculate the amount of heat generated. Heat dissipation in the silver(II) oxide region is about 20% less than in the silver(I) oxide region; also for silver--zinc cells, heat dissipation above 21 C ...

Heat dissipation at a graphene–substrate interface

Journal of Physics: Condensed Matter, 2012
The development of nanoelectronics faces severe challenges from Joule heating, leading to high power density and spatial localization of heat, which nucleates thermal hot spots, limits the maximum current density and potentially causes catastrophic materials failure.

Cellular Mechanisms of Heat Dissipation

1983
The past five years have seen a steadily accelerating advance in our understanding of the mechanisms and scope of mammalian thermogenesis. At the physiological level the recognition that brown fat is the major thermogenic organ not only in hibernators (Smith and Horwitz, 1969) but also in non-hibernators such as the rat (Foster and Frydman, 1978, 1979),

Heat dissipation for power switches

2022
Systems, methods, techniques and apparatuses of power switches are disclosed. One exemplary embodiment is a power switch comprising an outer housing; a power electronics board disposed within the housing and including a semiconductor switch structured to selectively conduct a current between a first power terminal and a second power terminal; a first ...

Coronal Heating by Dissipation of Magnetic Structure

Space Science Reviews, 1994
Coronal loops are heated by the release of stored magnetic energy and by the dissipation of MHD waves. Both of these processes rely on the presence of internal structure in the loop. Tangled or sheared fields dissipate wave energy more efficiently than smooth fields.
