Peltier Device for Engine Cooling Experiment

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.


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.
