### Powering Thermoelectric Module (Peltier) Answered

I am trying to understand how TEC modules work, and I think I have it figured out now, but was hoping that someone with more electrical knowledge could verify that I have it right. I am looking at this TEC module. My current understanding of this is as follows: 1. If I regulate the current to this module to a max of 2A, the maximum amount of heat that the module will move at DTmax = 0 would be approximately 75W. 2. If I regulate the current to this module to a max of 2A, the module will not exceed a DT of ~20C. 3. If I regulate the current to this module to a max of 2A, the voltage could range between ~4-6V, but would not reach 10V due to the limitation of DT. 4. Therefore, this module, limited to a max of 2A, would use at max 12W (approximately). Is that all correct? Second, I am comparing the above module to this TEC module. For this second model, my understanding is: 1. If I regulate the voltage to this module to a max of 12V, the maximum amount of heat that the module will move at DTmax = 0 would be 28W. 2. If I regulate the voltage to this module to a max of 12V, the module will reach its DTmax of 67C (theoretically). 3. If I regulate the voltage to this module to a max of 12V, the current could range between ~0.75-1A, but would not reach 2A due to the limitation on voltage. 4. Therefore, this module, limited to a max of 12V, would use at max 12W (approximately). So basically, it is a trade-off between DTmax and heat moved at the same wattage. Is that correct?

### keep getting a short when I connect a peltier module to DC power source

I am trying to power a peltier module (3.9V 9A 21.3W). I have connected it to a DC power source at 3v and I keep getting a short. I have tried different voltages below the 3.9V and am still getting the same result. Am I approaching this at too basic a level?

### How many peltier module i have to use for removing heat load of 250 watt?

i am using peltier modules  12706   ( vmax  15 v, Imax  6 A)               by checking it was running at   12 v  and 3.5 A and   peltier module 12715  ( Vmax  15V ,  I max  15 A )           was  running at  12 v  and 5.5 A I am using computer SMPS to run this peltiers so i can only get 12 v max is there any way to increase voltage to 15 volt.

### Controlling peltier module temperature base on CPU temps?

Can i use PWM on the motherboard or do i have to buy a separate controller? I plan to use it on a high TDP CPU like the Xen E5 1650v4.

### Can i use Copper Oxide to make a Home Made Peltier?

Here's the site http://sparkbangbuzz.com/copper-oxide-te/copper-oxide-gen3.htm .  i thought that i can use Copper(I) Oxide to make a Peltier Module. Peltiers are made up of semiconductor materials like bismuth telluride.

### Thermoelectric cooler/module

I'm working on a project with peltier coolers. I want to get it as cold as I can. What would be my optimum power source? Amps over volts? If it helps I am planning to hardwire the device. and I'll have plenty of room for mounting fans on the hot sides heatsink Here are the specs 50mm x 50mm x 3.64mm 245 - 320 Watts of cooling power Operates from 0-15 volts DC and 0-26 amps Operates from -60 deg C to +180 deg C Thanks

### How to evaporate/liquify acetone using peltier element?

Hello, I’m Georgios Grigoriadis and I’m trying to build a machine which could evaporate acetone and the liquify it. I want to use the Peltier element. My questions are: 1/ Is it possible to heat a metallic bowl, using the Peltier element, in order to to evaporate the liquid inside it (acetone) ? 2/ After having evaporate the liquid ( in my situation is acetone) I want to take the vapor from a tube to a metallic closed container, on which ( from the outside side) will be stuck a Peltier modules. Is it possible, using the Peltier module to freeze the container in order to liquify the (acetone) vapor? I also want control the temperature of the Peltier element but also how many time the Peltier module will work. Do you think that it is possible to use the Peltier modules in order to do that I want? If not what do you propose me ? Thank you very much for your interest and for any help. (I’m sorry if my English isn’t perfect ;), if something is very difficult to understand, don’t hesitate to tell me)

### Thermal Electric generation using peltier modules and a household plumbed radiator?

My idea was being energy conscious of some how incorporating thermal heat from the heating system of my house to power LED Lights in the rooms where there is radiators. I need to find a way to incorporate a make shift kit using peltier modules heat from the radiators and a natural way to cool in a bid to reduce the electric during the winter months. Advice is welcomed and opinions also taken onboard as regards to its productivity and if it will be able to do its designed task. Thanks.

### Stove fan problem - suggestions?

Hey guys I hope this is the right place to ask about this but apologies if not! I've got a home made stove fan powered by a TEC/Peltier module, and it worked ok for a long time but was pretty weak so I built a new bigger one to get a better result. This one uses 4x TEC modules (I think the code on them is 12706), with two series pairs connected in parallel (to double the voltage output, AND the current output).  So two pairs, with each pair in series for higher voltage, then the two pairs together in parallel. It works, but after a while it slows down & stops.  I think the reason is the top half heatsink is getting too hot from the stove where it needs to be kept cool. Problem is that i need these wide heatsinks both top and bottom in order to cover all 4 modules, so I'm not sure quite how to get round this problem? Can anyone give any good suggestions on this please? Many thanks! Jim

### What is the best wire for generating heat? Answered

I am making an Instructable for some contests. The basic concept is below: -Put two peltier modules on each bloodline on the neck -Put small heat sinks that takes advantage of wind on the other sides of the peltier modules -Use the electricity generated by the peltier modules (While skiing in ~20F) on a heat-generating device located near the hands -Cover the parts that I can with some fabric and possibly build it into a neck warmer or face mask So my question here is: What kind of wire should I use to generate the heat on my hands? I'm looking for high-efficiency and fast to generate the heat Also, do you see any flaws in my concept that I should change? Lastly, the most important question I feel I should ask here is: Will the peltier modules generate enough electricity to make a significant difference on the heat of my hands? My hands get cold enough to hurt when I go back into room temperature if that helps.
