Thermal spreading resistanceThis paper aims to calculate the thermal spreading resistance for a hyperellipse on a half space, with uniform heat flux. The effect of shape and aspect ratio on a steady state averaged temperature and the centroid temperature based thermal spreading resistance is studied....
A systematic study was performed using numerical modeling to understand the effects of thermal spreading resistance on the total resistance from junction to ambient for square and rectangular entities. Simultaneously, a literature survey was conducted to understand effects of thermal spreading resistance on...
Spreading thermal resistance of a diode-laser heat sinkAn approximate procedure is proposed for the determination of the effective width of a heat flux penetrating into a heat sink of a stripe-geometry diode laser. The procedure markedly reduces the computer work-time necessary for calculations of ...
摘要: Simple equations are developed for predicting thermal constriction/spreading resistances associated with heat transfer in electronics packaging applications.关键词: constriction resistance spreading resistance 会议名称: 1994 international electronics packaging conference ...
This calculation is for a heat source that is the same size as the base of the heat sink, therefore no spreading resistance is included in the calculation. Reference the blog postHow to design a flat plate heat sinkto learn about how to calculate the thermal spreading resistance. The therm...
The interpolation methodology quickly provides a thermal resistance versus copper coverage area curve. The interpolation approach is validated through detailed simulations on cases not included in the pre-generated thermal data. Such a quick prediction capability of temperature rise of exposed pad packages...
The effect of surface roughness was monitored according to the CMAS spreading and contact angles. A reduced spread area is likely to enhance the CMAS wetting resistance of coatings, whilst a smaller contact angle promotes greater wettability. The contact angle was measured at 0° for the NYSZ ...
For measurement of temperature, silicon spreading resistance temperature (SRT) sensor has been fabricated. It is ideally suited for present requirement of experiments because of its light weight, small size, moderate sensitivity and linear response in the temperature range of the interest....
