Freeze Tape Casting

Freeze Tape Casting Manufacturer:

A materials science company specializes in creating foams with specific porosity for use in electric vehicles, batteries, thermal interface materials and ceramic-metal interfaces. Utilizing a TECA thermoelectric cold plate as a component within the freeze tape caster ensures the manufacturing process remains environmentally friendly. Peltier cold plates use no freon, coolants, or chemicals of any kind. In this example, the customer has slightly modified a commercially-available, off-the-shelf (COTS) TECA cold plate to reach the desired -10C set point.

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.

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.

TEMPERATURE PREFERENCE TESTING

Creating Microclimates for Insect Subjects

Using TECA’s Gradient Bar System, a biology department at a U.S. university created a temperature preference device for small insects.

The insects were infected with various pathogens. The researchers wanted to create an environment where the insects chose a temperature benefiting pathogen replication/transmission and not host survival, thus determining whether pathogens alter their hosts’ temperature preferences.

Insulating their petri dishes and setting the entire gradient machine inside a larger incubator, the researchers created a microclimate and had excellent control over temperature fluctuations.

TEMPERATURE GRADIENT

Agricultural Research Using Temperature Gradient:

A department of the Canadian government uses two TECA Thermal Gradient Bar (TGB-5030) systems to conduct thermal behavior research on insects.

In the photographs shown here, the customer used two AHP-1200CPV Cold/Hot plates plus one Large Gradient Plate (p/n TGB-5030) and created a gradient area spanning from 4 °C to 33 °C. Two groups of insects were placed side-by-side on the gradient bar, in separate cages. This allowed the researchers to test two groups at the same time.

THERMAL GRADIENT BAR

The gradient plate shown is not TECA’s. It’s from a University. They had been running a hot plate on one end and a liquid cooled LHP-300CP with the plate in the evaluation of temperature preference in insects.

They needed better control and a wider temperature range and they wanted it on their existing plate. Many tests were run with the AHP-301CPV (shown) and the AHP-1200CPV to evaluate temperature uniformity and differential.

More and more researchers are looking into the versatile CPV line of cold plates to improve their tests with the CPV line of products and accessories. Call us. Maybe we can help you too.

BATTERY COOLING

R & D 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

A research and development team in Europe uses the TECA Model AHP-1200CPV Cold Plate with a TECA Model TC-1 Tube Chiller attached.

Their process is proprietary but involves optical material and measurements. The TC-1 Tube Chiller is designed to heat or cool fluid without introducing contaminants to the fluid.

The fluid flows through the flexible tubing (various tubing diameters are possible) within the plate surface.

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:

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.”
