COOLING LED CHIPS

Cooling LED Chips:

The customer was looking for a cooling solution for LED chips. With a heat load as high as 45 watts at times, the customer needed to cool the chips quickly. The customer was able to utilize TECA’s Loaner Program and test the AHP-301CP cold plate before purchasing.

Satisfied with the AHP-301CP performance, the customer has since purchased several more and sold them as a part of his total system to his clients.

The AHP-301CP series is replaced by the newer and updated AHP-401CP series.

CANADIAN FOG BOX

Below are few pictures of the “Canadian Fog Box” that our customer constructed using TECA’s AHP-300CP cold plates, power supply, and TC-3400 PID controllers.

The interior of the box is covered with mirror finished aluminum to reflect the ultraviolet rays from the bulb in the bottom. The top is normally closed as well. The interior ambient temperature of the box is maintained @ 122 °F. subjecting the 2 insulated glass units (laying at a 45° angle) to intense UV radiation similar to strong sunlight. The upper portion of the glass is chilled to 70 °F. by your cold plates. This is maintained for 1 week 24 hours/day.

The insulated glass unit is then inspected for any condensation inside where the cold plates contacted the glass. Any condensation indicates impurities present inside the unit, which indicated faulty materials containing volatile gasses, which would lead to premature window unit failure.

Any other ‘fog boxes’ use water flow cold plates to maintain temperatures. Our customer during a research found TECA’s cold plates and decided to give them a try to eliminate the hassle and mess of water plates.

The thermoelectric cold plates (Peltier cold plates) have performed excellently to date, reaching and maintaining the 70 °F. quickly and without incident.

TITER PLATE COOLING

Titer Plate Cooling:

The WWW brings many to TECA’s door. These particular customer requirements were filled by an AHP-300CP Peltier cold plate. He needed to control the temperature of a 96 well titer plate in a new product design. But he needed just a few things the standard unit didn’t provide and he didn’t need some that it did provide. He wanted a 24 VDC heat cool system with continuous fan operation and a custom tap pattern on the cold plate.

In short order the TECA sales team assigned a preliminary part number, passed the requirements through to engineering and together the first units were modified and shipped. This gave the customer plenty of time to work with the solid state cold plates and refine his requirements into the custom design he uses today.

The AHP-300CP series is now replaced by a newer and more efficient model the AHP-470CP series.

MOTOR SPORT

A rally car racing team had a need to chill drinking water inside their moving vehicles, while they raced through very hot desert conditions. A solid state cold plate based on TECA model AHP-300CP.

The AHP-300CP thermoelectric cold plate (Peltier cold plate), which draws power directly from the car battery, was the solution to maintain the temperature of the water at an acceptable level. With a ready supply of chilled water, the racing team could drive at peak performance.

The AHP-300CP series is now replaced by a newer and more efficient model the AHP-470CP series.

LOW TEMPERATURE CASCADE

A cascade sandwich is what we called this that day, built using two AHP-300CP cold plates. The customer needed a fairly large mass cycle between two extremes. The mass and size of the load were limiting factors. The pictures and assembly look crude, and it was, but they were also effective.

It was determined that a final design based on standard components would be successful and it was.

The AHP-300CP series is now replaced by a newer and more efficient model the AHP-470CP series.

CONDENSATION TEST

A company that offers a broad range of door and window components and related building products with proven product lines and a multi-state collection of modern manufacturing facilities uses the AHP-150CP in a Canadian Fog Box, for testing double pane windows for condensation.

The AHP-150CP has been replaced by a newer and more efficient model the AHP-250CP series.

As a component in an OEM laboratory chamber, the AHP-150CP condenses out moisture to control humidity. The chamber is primarily used in hospital laboratories. The small size of the AHP-150CP helped reduce the footprint of the chamber and helped increase the work space within the chamber.

The AHP-150CP is maintenance free and the reliability of its thermoelectric cooling technology made our smallest cold plate the perfect OEM solution for this customer.

The AHP-150CP has been replaced by a newer and more efficient model the AHP-250CP series.

LIQUID COOLED COLD PLATE

Liquid Cooled Cold Plate:

Our customer asked for a quote on delivery and price for the LHP-800CPHC. He then asked if we had a liquid cooled version of the AHP-1200CPHC (15″ x 7.3″ plate)? The product had been in the works but on the back burner. This customers request pulled it to the front.

We offered an LHP1200CP. It would be liquid cooled with 15 x 7.3 cold plate requiring 24 VDC input. The customer later set it up with a water pump and a radiator/fan arrangement to provide a recirculation cooling water path rather than connecting to the tap and sending it down the drain.

COLD PROBE

Cold Probe Medical Application:

A Medial Doctor was interested in a Peltier based “Cold Probe” to anesthetize the skin prior to treatment. He wanted an instrument that ran on batteries based around the Otoscope or the Ophthalmoscope with interchangeable heads. It was a medical application, a prototype and a long shot one at that.

He came to TECA with some rather limiting criteria to do a big job considering the load human skin presents. We did our best and gave the good Doctor his cold probe. We designed it, packaged it, powered it and built it. But not many folks really needed it. Not a complete market success but a technical one.

INDUSTRIAL ADHESIVE COOLING

Industrial Adhesive Cooling:

These folks needed to cool a thick fluid that ends up being gaskets when robotically dispensed. A custom version of our AHP-1200CP fit the bill perfectly. Now the product is dispensed consistently because of the temperature control provided by thermoelectrics.
