Temperature controlling system with peltier battery?

AI Thread Summary
The discussion revolves around designing a temperature stabilizing system for solar cells using a 12V Peltier device and a PC fan. Clarification is sought regarding the use of a Peltier battery, with suggestions that it may refer to a Peltier cooler in reverse. Key challenges include ensuring adequate heat flow to maintain a temperature differential, as both sides of the Peltier device can equalize quickly without proper heat management. The electronics involved are relatively straightforward, requiring a battery, possibly a temperature sensor, and a fan, with advice to consider using multiple batteries for sufficient voltage and current. The complexity lies in accurately calculating heat flow equations for effective system performance.

Hello everyone!
I have a thesis to design a temperature stabilizing(controlling) system for solar cells.I need to use 12V Peltier battery and a simple pc fan.Any further help is appreciated.

It is also unclear what you are trying to do.

Peltier battery? Is that a Peltier cooler in reverse?

If so, how are you going to ensure enough heat flow through the cooler to run a fan? Remember it's the flow of heat that powers the battery. A simple difference in temperature won't do since both sides of the battery will soon be at the same temperature. You need a hot side that stays hot and a cool side that stays cool.

The electronics are simple. The battery. Possibly a temperature sensor/switch. A fan. Use multiple batteries in series or parallel to get the fan's voltage and current.

The hard part will be the heat flow equations. For a non-thesis some simple equations would get you in the ballpark, but properly done these will be difficult.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
