Basic question for somebody to help me with

Guest
Hey,
I have never posted here before, But hopefully somebody can help me.
I'm very amateur when it comes to electronics so any help is great. I
am installing a soda pop can cooler in my car. To describe this most
simply:
I have a fan and a module. Two different things that need power. They
both are set to run off of my 12V battery car power. I need to find
some sort of a two-direction switch that both of them can be wired to
so that the fan will run the same direction no matter what direction
the switch is, but so that the module will switch according to the
direction the switch is. (This is How the pop can can be either cooled
or heated). But the fan needs to run the same direction. I hope this
makes sense. Can anybody help with advise?

I assume you can work out how to wire up the switch so that it applies
alternate polarity, as required, to the module?

Look up "full wave rectifier" and put one of those to the fan.

Alternatively, use 2 switches, one to switch on and off the whole lot, the
other just reverses the polarity across the module.

I'm assuming this is a peltier type module.

NOt using a peltier type module. At least I don't think so. I'm using
the (UT) module in the (TEC) module section. surprisingly very
powerful with only 12V feeding it! I've done tests with 100 degree
water in a pop can, and timed the rate of temperature drop. Pretty
impressive. entire can of water fromm 100 to 42 degrees in 24 minutes.
thanks for your help. HOpefully I can get this thing hooked up.

If it is not Peltier, what is it?
Where did it come from?
Who makes it?
Is it a mechanical or a solid state cycle?

In Mexico the water faucets are labeled "C" and "F". "CALIENTE" and
"FRIO"? No, "COLD" and "FREEZING"! ;)

Relative to Mexican ambient temperatures or those conducive to human
life?
