Does the mounting orientation or side of a heat-sink matter?
edit:
So I have the following heatsink:
But I want to mount this way: …

How to size heatsink for this thermoelectric cooling application
I want the cold side of this TEC(Peltier module) to be held at 0°C and need to size a heatsink. … So it means, at this very early stage I didn't even come to a point to size a heatsink. …

When to use a heatsink for a voltage regulator?
Power is I*V but Im wondering when really a heatsink is needed. Sometimes the current flow from the regulator output is 1mA but in an other project 20mA or more. … Is there a rule of thumb for when to concern about heating and considering to use a heatsink? Consider operating time is 12 hours. …

How to size heatsink for this thermoelectric heating application
As a part of experiment I also want the one side of this TEC(Peltier module) to be held at 50°C(where the room temperature is 25°C) and need to size a heatsink this time for the cold side. … And in this case, the heatsink will act as a heat reservoir. But as far as I understand, this time to the cold side I have to attach a heatsink otherwise the cold side will struggle. …

A question about heating of a slowly turning off MOSFET
ΔT = P × θ = 1 × 62 = 62°C
Let's say the ambient temperature is 35°C, then the total temperature becomes
35 + 62 = 97°C which is smaller than 175°C
First conclusion was the MOSFET does not need a heatsink …

Some questions about MOSFET power, temperature and LTspice
I currently calculate the heatsink by considering the power dissipation as 15W even it is a single pulse. … I made this one clear enough, pardon my english.
2-) I found out that LTspice has a new feature which can simulate the temperature of an nMOSFET called: SOAtherm which can also be used with SOAtherm-Heatsink …
