Peltier Device for Engine Cooling Experiment

[ganapathyakhil]

Hello everyone,

I am conducting an engine cooling experiment where I am trying to reduce the inlet temperature of an engine from ambient air temperature (32 degrees) to 10 degrees. I am using a Peltier device placed in a tube. The required heat that needs to be removed to achieve a 10 degree reduction from 32 degrees is 145.95 watts.

The following are the specifications for the device:

• Air flow rate: 5.6585 x 10^-3 m3/s
• Mass flow rate: 6.5946 x 10^-3 kg/m3

I am having a hard time finding a device that matches these specifications and I am in urgent need of assistance. I would be very grateful if anyone could provide any information on Peltier devices that match these specifications, including technical specifications, pricing, and lead time. I would also like to know if there are any preferred combinations of devices that can be used to achieve my goal of reducing the temperature in a forced convection.

Additionally, if there are any additional parts or controllers included in the package. Please provide any calculations that were used to determine the above specifications.

I am also open to suggestions on any other solutions that can be used for this experiment. Please let me know if any additional information is needed from me.

I would like to inform that I am flexible to change the diameter of the inlet pipe according to the device that is used.

Thank you in advance for your help.

Greetings,

Several existing posts on thermoelectric modules are linked below, which describe processes for interpreting device specifications and making design calculations.

Achieving a cold-side thermal flux of ~150W under the described conditions will likely require the use of several modules, and probably close to a kW of electrical input power. If your purposes are strictly for laboratory research it may be a useful tool, but it is unlikely to offer benefit in practical use.

Thermoelectric Modules: Device Specifications

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

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. Electrical Drive Considera…

Modeling Thermoelectric Systems

This post is part of a series on thermoelectric modules (TEMs), also known as Peltier devices. 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 …
