Questions tagged [peltier]

The Peltier effect is a reversible physical process which is exploited in Peltier cooler/heater. The flow of current through this device pumps heat from one plate of the device to the other. This can be used to both heat and cool electronic components.

How to drive a Peltier element?

Maybe the underlying question is what the Voltage-Current curve looks like. Can I drive it from a voltage source (like you drive a heater) or from a current source (like you drive an LED)? Or even different than those two options? ADDITIONAL1: Say…

Can Peltier devices be cascaded?

Can Peltier devices be cascaded to create a bigger temperature difference? Like mounting one on top of anther one to increase the maximum difference from 60 degrees C to 120 degrees.

Is it worth to try making peltier based refrigerator?

I built a box from 5cm thick Styrofoam with outer dimensions 60x55x80cm. I wanted to use it as a fermentation chamber for home brew purposes. The reason why I did not choose regular (some used cheap) refrigerator is I need to have it in a small…

Building a safe low-temperature heat box: heat sources

I'm not sure if this is more of a physics or electronics question, but here goes: I use a heatbox with a temperature in the range of 80-100F for warming wax (for sculpture modeling). My current heatbox is a Peltier-based thermoelectric wine cooler…

Is it possible to obtain very small Peltier modules with fast response times?

I have a thin 2x2 mm surface that I'm trying to cool by 5-10 degrees Celsius in 1 second or less. Some very rough back-of-the-envelope calculations reveal that I need to remove ~50 mJ of energy to do this. I've been thinking of using a Peltier…

Corner of Peltier module is very hot

I've bought a generic TEC1-12706 Peltier module and I'm having trouble making it work. I wired it to a 12 volts DC, 8-amp power supply, and connected the hot side to a fan & heatsink with thermal grease. Turning it on, I noticed that condensation…

Are peltier devices linear?

Say I've got a peltier block that is rated at 15.2V and 6A, providing 90W of cooling power to one side. Will I be able to operate it at 5V, and will it draw 2A, providing 30W of cooling power? EDIT: sorry, error above. :P brain was not working. 5V…

TEC1-12706 Peltier run from diffirent voltages

My question relates to a video I saw on youtube. In this video, the user is cascading 3 TEC1-12706 peltier modules to achieve temperatures of -50 on the cold side of the cascaded peltier. The TEC1-12706 is a 12V 6A unit, but in this video the…

Finding a 12 V Peltier module that reaches less than 0 °C on the cold side

I am making a small cooler box using a Peltier. At first, I used a Tec1-12706 without researching first, and it barely went under 12 °C at the cold side. I need a Peltier module that is 40 mm x 40 mm that is 12 V that goes to at least under 0 °C. I…

Are cheap Chinese peltier modules efficient?

I'm developing a product that cools beverages and trying to decide what peltier modules to choose. I've noticed that some companies like Laird Technologies, CUI inc and TE technology offer expensive coolers, while there are many generic offerings…

What happens when you connect hot and cold sides of Peltier device together?

I would like to know how the Peltier device would act if you heat sink the hot side WITH the cold side. Would it just sit there and consume power? I need something to consume ~15 watts or more at 14V. Was thinking of other possibilities than a power…

Thermoelectric cooler powered by 12V battery too hot?

I am very much an amateur when it comes to this stuff. Basically I have a set up that goes as follows: Aluminum plate -> TEC (cold side) -> TEC (hot side) -> heat sink -> fan. The battery is 12V 7Ah (SLAUMXNPG7-12). The TEC is 12V 4-6A…

A device like a Peltier cooler which transfers heat to another surface not in direct contact with the cold side?

Back when I was a kid and first learned about Peltier coolers, I mistakenly thought they had the ability to transfer heat remotely from one surface to another via wires. I didn't realize the heat transfer took place within a set of PN junctions in…
