Greetings, My experience is that peltier devices are one of the most commonly misunderstood in the electronics realm. It’s quite difficult to get a grip on the nuances involved without a decent footing in thermodynamics and electronics alike, and it wouldn’t surprise me in the least if the designer(s) of the product in question were a bit light on either. A key idea is that the nameplate numbers on a peltier device usually only describe two very specific endpoint conditions, and that actual practice usually operates somewhere on a continuum between the two, or below. Operation at ~30 to 50% of nameplate ratings tends to give the most thermal bang for the electrical buck, so running two (electrically) in series rather than one at maximum capacity from a given electrical source would be likely to give a more desirable result. The posts linked below were an attempt to explain some of the considerations involved in using the darn things effectively. From an “I’m out of warranty and I want to try fixing it” standpoint, finding something with specifications as near to original is perhaps one’s best bet, but in pursuing that avenue one assumes all the risks that attend it. > [@Thermoelectric Modules: Device Specifications](https://forum.digikey.com/t/thermoelectric-modules-device-specifications/13255): > > This post is one of a series on thermoelectric modules (TEMs, also called Peltier devices) which convert an electrical input directly to a heat pumping effect. Here, basic concepts of temperature and thermal energy are discussed, the general behavior of TEMs described, and a method for modeling device performance mathematically introduced. Subsequent pages show how this information can be used to make calculated system performance estimates, and highlight various other considerations relevant … > [@TEM Application Considerations](https://forum.digikey.com/t/tem-application-considerations/13256): > > This page is part of a series on thermoelectric modules (TEMs) also known as Peltier devices. Previous pages in the series discussed the basic function of these components and techniques for modeling and predicting the behaviors of a TEM when used as part of a thermoelectric cooling system. This page covers a number of electrical considerations relevant to the operation of a TEM, and mechanical considerations regarding their installation as part of a thermal system.

The prior page explored the basic function of TEMs and a method of describing their behavior mathematically based on information likely to be found in product literature. This page steps through a process of developing a thermal model for a system using a TEM to create a small beverage cooler/refrigerator, showing how different portions of the physical system are modeled, how product information can … > [@Thermoelectric Generation](https://forum.digikey.com/t/thermoelectric-generation/13777): > > To this point in the series on thermoelectric devices (related posts [here](https://forum.digikey.com/t/thermoelectric-modules-device-specifications/13255), [here](https://forum.digikey.com/t/tem-application-considerations/13256), and [here](https://forum.digikey.com/t/modeling-thermoelectric-systems/13254).) the discussion has focused on their use as a cooling/heat pumping mechanism. The underlying phenomena also work in reverse; if one maintains a temperature difference across a thermoelectric module (TEM) by external means, it’s possible to extract a portion of the thermal energy required to do so in electrical form, without need of any moving parts. When used in such fashion it is common to see TEMs refe… > [@tangoalpha](#): > > I think my issue was something caused the pump to stop moving the water. A pump failure or fluid flow restriction in such a system as I understand it would seem extremely likely to result in failure of a thermoelectric device if the system design does not incorporate suitable protections. --- _[View the full topic](https://forum.digikey.com/t/chilipad-ooler-tec1-16109-equivalent/55482)._
