Another Day, Another “A”

Thermoelectric Cold/Hot Plate Replaces Liquid Nitrogen:

TECA’s cold/hot plates utilize thermoelectric cooling, a solid-state method of heat transfer. Also called the Peltier Effect, this technology is valued for its reliability and lack of maintenance needs. For over a decade, TECA cold/hot plates have been cited in peer-reviewed, published academic research papers. Pictured here is our youngest known researcher, a 7th grade student who designed a physics experiment for her school science fair. TECA could not pass up the opportunity to support a budding scientist and lent our Model AHP-301CPV, free of charge.

thermoelectric cold plate

Lisa, a 7th grader, used the AHP-301CPV in her science fair project, Electric Ice. Following the methods from a paper published in the journal Science, she obtained pyroelectric crystals, which develop an electric field in response to a temperature change. When the pyroelectric crystals are cooled in a controlled manner, their electric field affects the freezing point of the moisture in the air that condenses on them.

Unlike the scientists in the Science paper, Lisa did not have access to large amounts of liquid nitrogen to provide the cooling. Enter TECA Model AHP-301CPV Cold/Hot Plate. The pyroelectric crystals, housed in copper cups, were placed on the cold plate surface. Using the AHP-301CPV’s integral temperature controller and included communications software, Lisa programmed the cooling to ramp down by 2°C per minute, from room temperature to -20°C. A video camera recorded the condensation of the ambient moisture and its subsequent freezing. By comparing the time base of the video with the data captured by the AHP-301CPV’s communications software, Lisa was able to measure the freezing temperature for 3 separate configurations: within a positive electric field, a negative field, and no electric field.

Museum Exhibit, Thermoelectric Cold Plate

Educational use for thermoelectric cooling cold plate:

A large children’s science and technology center in the Midwest, specializing in hands-on exhibits, has been using multiple TECA Cold/Hot Plates, Model AHP-1200CPV. The AHP-1200CPV supports part of an exhibit teaching children about insulation. The built-in temperature controller and attractive, ergonomic exterior are perfect for the museum’s display.

CONDENSING VAPOR

Condensing Vapor: AHP-470CP in Laboratory Reactor Instrumentation

condensing vapor   cooling vapor stream

In a chemical process (catalysis), the customer uses several TECA Model AHP-470CP Cold Plates to condense methanol out of a vapor stream and collect liquid in the 100 mL glass vessels shown. The AHP-470CP offers a convenient small size and is customizable to the end user’s needs.

Please see the “Options” section on the product data sheet to learn more.

Equipment Testing & Maintenance

Equipment testing and maintenance:

Equipment Testing & Maintenance  Electronics Testing & Maintenance

Three AHP-1200CPV Cold Plates are running continuously and in tandem at 17 °C to monitor satellite equipment. The customer has added air deflectors of his own design. TECA offers standard air deflectors as well. The customer applies approximately 50 watts of heat to the cold plate.

BATTERY COOLING

R & D Battery Cooling:

battery cooling

In this example, the customer is using TECA’s AHP-1800CPV to keep a 60 pound lithium ion battery cool during R&D testing. This saves the customer the trouble of using a plate with pumped coolant to cool the battery, which was the original method.

The customer reports that upgrading to the TECA AHP-1800CPV “makes testing much easier”.

The AHP-1800CPV is the largest thermoelectric cold plate on the market with a plate surface area of 12.80 x 13.30 inches.  The large surface area and robust cooling power were ideal for this application.

FIBER OPTICS

Fiber Optics:

fiber optics

The customer makes fiber optics and related components and subsystems, they use an AHP-1200CPV cold plate for testing components.

They are using it to run temperature test on them, they set the temperature, and it goes to temperature and sits there, heating or cooling.

“It works well”.  Before they were cobbling together home brew solutions with a heater here, a circuit and a fan there but it’s nice to have a system that does it all.

COOLING ASPHALT SAMPLES

Cooling Asphalt Samples:

cooling asphalt samples

An oil refinery runs tests on asphalt samples at different temperatures.

TECA Model AHP-301CPV Cold Plate is currently being used during the course of the customer’s testing.

The customer says, “We have used this unit at different temperatures, and it has performed well. Thank you for your follow-up on the performance of this device.”
