Talk:Thermal runaway

[edit] LEDs

Would it be an idea to add LEDs to this list of things that can experience thermal runaway? Stwalkerster 19:03, 11 September 2006 (UTC)

Or in fact, go through the "what links here" page? Stwalkerster 19:05, 11 September 2006 (UTC)

[edit] Not thermal runaway

Deleted this:

"It is seen in satellite TV receivers, portable computers or industrial programmable controllers. When the air temperature that surrounds the equipment is over a threshold level, the temperature starts a heat run, a thermal runaway that makes the electronics fail, and the electronics then need to be cooled down and reset to work properly again. This problem is caused by the high frequency chopped power supplies, where MOSFET transistors are used."

Why? If equipment works when cooled, it has not experienced thermal runaway. Runaway is a destructive phenomenon. If equipment is only temporarily out of action due to overheating, this does not mean runaway has occurred.

And hf smpsus don't in any way cause thermal runaway. Tabby (talk) 05:09, 1 April 2008 (UTC)

[edit] CPUs

Deleted:

"This problem is predicted to be more common in the future. As devices become smaller, static power dissipation contributes to an increasing portion of overall CPU power consumption. Leakage currents increase by a factor of close to 100 over the temperature range of a CPU. As a result, it is likely that this thermal runaway will be a common problem with future CPUs ^[1]."

Why? Someone may have predicted it, but that doesn't make it accurate or even realistic. To suggest that a high ticket complex IC like a CPU is incapable of including protection against runaway is truly unrealistic.

A lot of people have predicted a lot of things, doesn't make those predictions valid. Tabby (talk) —Preceding comment was added at 05:20, 1 April 2008 (UTC)
