MR gradient coil heat dissipation
Magnetic Resonance in Medicine, 1995AbstractThe temperature responses of five different gradient coil designs were modeled using simplified engineering equations and measured. The model predicts that the coil temperature approaches a maximum as an inverse exponential, where the maximum temperature is governed by two parameters: a local power density and a cooling term.

The dissipation of frictional heat
Applied Scientific Research, 1955The 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.

Dissipation of Heat by Radiation
Transactions of the American Institute of Electrical Engineers, 1930Heat dissipation is an ever-present factor affecting the design and operation of many kinds of electrical equipment. Usually, the problem is to get rid of heat due to losses. Sometimes the problem is how to conserve heat. Radiation, or convection, or conduction, or combinations of these, enter into all cases.

HEAT DISSIPATION OF PRIMARY AND SECONDARY BATTERIES
Unmanned Spacecraft Meeting 1965, 1965Calorimetric 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 ...

A heat dissipation tutorial for wearable computers
Digest of Papers. Second International Symposium on Wearable Computers (Cat. No.98EX215), 2002Wearable computing brings computation much closer to the user for everyday tasks and may be worn during most of the day. However, with CPU and wireless network intensive applications, higher power microprocessors and radio links are necessary resulting in increased heat generation.

Power matching based dissipation strategy onto spindle heat generations [PDF]
Applied Thermal Engineering, 2017 To overcome the imbalance between spindle heat generation and dissipation caused by existed spindle cooling strategies, this paper develops a power matching based cooling strategy for motorized spindle unit.

Cellular Mechanisms of Heat Dissipation
1983The 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
2022Systems, 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 ...
