temperature delta when testing at cold and hot |
Hi all,
Part of my work involves characteristing electrical components at cold
(0C), ambient(25C) and hot(70C) temperature. Had a heated discussion
with one of my colleagues today because of the results seen. The
temperature of the equipment was shown to be 15C at cold and 60C at
hot. The argument was about why is there a temperature delta difference
between the enviroment and the equipment at hot (~5C) and cold(~15C)?
The equipment produces heat. Any ideas? Thanks
.

Well, gee, just a wild stab in the dark of a murky explanation. But is
it possible the equipment is warming itself? You don't seem to have
mentioned whether the delta is the equipment hotter or colder than
the environment. Maybe you could explain how you calculated that
delta?
