Electronic output
(OP)
Hi
I'm looking for information on the temperature output of electronic circuits. I am to develop cooling methods but need to know what sort of temperatures i am dealing with.
I'm looking mainly at vehicles but only need a rough idea of what temperatures are seen.
Cheers

RE: Electronic output
Unfortunately, I don't have a good number for you if the component is actually mounted to the engine itself....
RE: Electronic output
What I am really looking for is just the output from the electronics because i have lots of data on engine temperature etc.
thanks again
RE: Electronic output
Heat from circuitry will range from milliwatts to tens of watts, depending on the application.

RE: Electronic output
I'm relatively new to the field of electronics in regard to the heat output.
the heat outputted from a circuit in a car will only be a few watts though?
thanks
RE: Electronic output
The Holley electronic ignition module draws a maximum of 40A, presumably at 12V:

RE: Electronic output
For instance, if you have a 400W stereo amplifier under the seat of the car, and the stereo and speakers are inside the car as well, all 400W is going to be dissipated into the car interior somehow. But if you have a 200W power supply under the dash that is powering an ignition computer in the engine compartment, and the power supply is 80% efficient, only 40W of heat is being dissipated into the interior. The rest is going into the engine compartment.
I just made these numbers up of course. You will still need to do some more research as to what is being used in cars, and of course that varies greatly as well. My Chevy does not have many do-dads inside, but my brother's Mercedes has more electronics than most small convenience stores!

RE: Electronic output
engine is cold, so I would put the lower limit to -40
C (-40 F)
