I'm making one of these coolers from scratch and need a simple piece of advice. I have a refrigerator box 2" thick, so I have to put a 2" thick aluminum block through it and mount the peltier plate to one end and heatsinks on both. My question is whereI mount the peltier plate. Do I mount it inside the box and send the heat through the box to the outside or do I mount the plate on the outside of the box (naturally on the aluminum block between it and a heatsink) and send the cold into the box from the outside. HELLLLLP! Thanks everyone.. if possible.. email me tha answer (alexii4@yahoo) ~m

on the inside you can use a 120mm CPU  cooler on the out side and Right stuff foam to seal it all in but on the inside you will need a heat sink and small fan use clear silicon to seal around it if it's a wet box don't use a fan just put a copper plate DON'T RUN A peltier with out a sink of some type on both sides

i have a big cooler it's about 2ft x 2ft x 5ft i made in to one i use a pair of 127watt peltiers and 2 copper plates 3"x 8"x 1/8" and a pair of old zelman cpu fans on the out side thermal epoxied to the hot plate  and a small 80mm cpu fan on the cold plate
from room temp in the 80+deg to low 40deg in about 10mins i have a tem controlled using PWM driver 12-18v in and 32khz PWM +booster can push 20 amps at up to 18volts even if the input is 12volts

i built a lot of LED controllers and the same rules apply to peltiers 
just eat a lot more

We're going to build a dog house and I would like to be able to control the temp in there. In OK the summers get hot and humid, and there are a few freezes in the winter. A lot of the options out there made specifically for pets/pet houses are expensive. Do you think this would work to heat/cool a medium sized dog house in the elements?

It wouldn't work very well without a door. And as long as there is a good door and the floor is off the ground it will stay warm enough for most dogs in the winter. For summer you just remove the door and add a fan if it's too hot. Best summer method is a porch, either on the house or the dog house so that the dog can lay in the shade without being stuck in a hot enclosed space.

I'm not sure how well this really would work, it might a wee bit but the TE unit still isn't pulling the heat away faster... Also it's a 92MM fan not CM 92CM is nearly a metre...

In the I will look into up-ing the power to it maybe

[killerjackalope]

Hmm Within it's limits it might help a huge amount...

This uses a peltier right?
