Sometimes I think my interest in thermoelectric cooling and excitement about its potential for so many different applications has a genetic basis. I vividly remember back in the early ‘60s, my dad—an inveterate tinkerer— came home from work with an armful of thermoelectric components and a fascination with the...

Our goal is to continue setting the standard in thermoelectric cooling by monitoring and improving our operations to meet our customers’ needs and exceed their expectations. A former division of Borg-Warner, TECA was spun-off as an independent company in 1984. We can fulfill all of your cooling requirements, whatever your application. In fact, our engineers may have already developed a...

catalog 2011 working on.qxp 6/28/2011 1:48 PM Page 2 Thermoelectric Technology The Peltier Effect Thermoelectric cooling, is a solid-state method of heat transfer through dissimilar semiconductor materials. It is also called “the Peltier Effect” after the French watchmaker who discovered the phenomenon in the early 19th century. Like their conventional refrigeration counterparts, thermoelectric cooling systems obey the basic laws of thermodynamics. However, the actual system for cooling is different. In a conventional refrigeration system, the main working parts are the evaporator,...

catalog 2011 working on.qxp 6/28/2011 1:49 PM Page 3 Applications Product Notes General Product Notes: TECA builds both air cooled and liquid cooled products. The model numbers of the products (example: AHP-1200XMHC) can be very descriptive of the product. Air cooled products (prefix -AHP) use fans and finned heat sinks to transfer heat. Liquid cooled products (prefix-LHP) require a flow of water or cooling fluid to dissipate the heat. Most product families offer a selection of DC or AC voltages and temperature controllers detailed with complete part numbers on their individual catalog...

The enclosure temperature or the interior temperature is the temperature range you wish to maintain inside the enclosure. The difference between the two is the design temperature differential (delta T). Look at these temperatures with care. What is the real maximum ambient? What is the real maximum enclosure temperature?...

The desired temperature can be at the cold plate or at a location on the item being cooled. This means that the cold plate might be colder than the item being cooled. The difference between the two is the design temperature differential (delta T). Make sure to use the cold plate temperature when working with the performance curves. Heat Loads...

SOLUTION: Using four TECA AHP-1200CP cold plates, one was placed in the seat, back, and in each arm rest of the throne. Raw aluminum was then screwed onto the plates, and the throne surfaces reached close to -20C! Visitors to the museum can sit on the throne to feel the chill. The "ice" in the picture is...

The desired temperature can be at the cold plate or at a location on the item being cooled. This means that the cold plate might be colder than the item being cooled.

This leads to evaporation and condensation within the sample vials, and problems of gas transfer through sample needle to mass spectrometer (liquid condensation blocks gas flow through capillary tube). SOLUTION: USF Geology Stable Isotope Laboratory installed a second auto-sampler with a TECA AHP-1200CPV cold plate to keep samples at below...

The desired temperature is the fluid temperature at the outlet or at a location at the item being cooled. The difference between the two is the design temperature differential (delta T). Typically the fluid temperature has to be a little cooler than the item being cooled. Make sure to include any gradients from the fluid to the test item. Also include any increase or...
