Natural heat dissipation
WebNatural convection is produced by density differences in a fluid produced by temperature differences in the fluid (e.g., as in “hot air rises”). Global atmospheric circulation and local weather phenomena (including wind) produce convective heat transfer. Fig. 14.4 illustrates natural convection around a hot object. Figure 14.4. Webwith and without onboard heat genera-tion (heat transfer from a copper trace to a plane in a PCB when power is sup-plied to the PCB component) to determine whether onboard …
