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.

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

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.”

HIGH SPEED CRYSTAL OSCILLATORS

High Speed Crystal Oscillators:

High Speed Crystal Oscillators

The customer makes high performance crystal oscillators and atomic clocks for satellites and laboratories and they needed something for temperature control and stabilization.

They found TECA and the AHP-301CPV, tried one and say it is “working fantastic”. Well enough to order more for production, quality and engineering tests. They use them to maintain a stable temperature of the oscillator which in turn provides a stable frequency.

COOLING MOUNTING WAX

Cooling Mounting Wax:

A product design engineer at a medical device company needed a way to cool wax blocks holding film. The wax is printed directly onto the customer’s aluminum tray. Before discovering TECA products, the customer was placing the aluminum tray in a refrigerator and mechanically removing the wax by scraping it off with a metal blade.

TECA’s AHP-1200CP Cold Plate is a better solution. The customer is happy to have found an affordable cold plate to dedicate to his cooling task.

Please view the video provided by our customer to see how quickly and easily the wax is now removed (no more scraping!).

CHEMICAL WASTE TRANSPORT

Chemical Waste Transport:

Here’s an application that our engineering crew would love to put into greater use if they could figure out where and how. A specialty gas company called. They wanted to transfer toxic and corrosive liquids from big to small containers for lab use. The process had been taking several minutes with too much wasted product.

They knew because of the conditions a natural head pressure in the big container that they could use a cold plate to cool at the receiving vessel (Ø 1.5″ x 12″ bottle) to create a driving force which moves the fluid.

We didn’t go into the physics of this, we trusted what the customer said and worked with them. When they tried an AHP-1200CP it was fantastic. It turned 4 minutes and a lot of waste into no waste and 40 seconds.

PERFORMANCE TESTING

Performance Testing:

Customer needed to test low-temperature performance of inertial measuring devices.  In this application of low temperature thermoelectric cooling; the user is testing inertial measurement devices over a temperature range.

The devices as well as the TECA cascaded cooling assembly are subjected to various rotational and acceleration stimuli while device temperature is controlled.  The custom thermoelectric cold plate cascaded (Peltier cascade) was built up from a standard Model AHP-301CP cold plate.

The finished test fixture was able to function with a maximum rotation rate of 1700° per second and 50 g acceleration.  The rotation is evident in the photo. By using a standard product as the basis for the cooling system, higher costs associated with a custom solution were avoided.

VACUUM CHAMBER

Vacuum Chamber:

Some engineers at Lucent wanted to cool devices inside a vacuum chamber and they didn’t want to reinvent the wheel. TECA’s been making devices like that for decades. They had a load of 10 to 20 watts generated and wanted -40 °C with about 15 °C to 20 °C water available.

A Custom LHP-800CP / LHP-300CP cascade, controller and power supply were supplied for a reasonable cost in a reasonable time frame.
