An associate professor of Cosmological Physics at a local university traveled to Antarctica for research. TECA’s High-Capacity AHP-1200CPV Cold Plate went along with him! The AHP-1200CPV is being used for testing on a NASA project.
A research organization had a problem with overheating of their equipment in a chemical-vapor deposition reactor TECA’s AHP-301CPV Cold Plate cooled the equipment and improved the performance of the customer’s system.
The customer was able to avoid system failures, which allowed the completion of a research project.
A company specializing in hydrogen fuel cell technology required fast cooling of a fixture. The fixture is bonding multiple thin materials and can be heated up to 100 °C. The fixture needed to be cooled to the point where it could be handled by technicians—within a 5 minute time frame. Using two AHP-1200CP Cold Plates from TECA, the customer has created a system where a heat sink is cooled on one AHP-1200CP Cold Plate while a hot fixture is sandwiched between a second AHP-1200CP Cold Plate and a pre-cooled heat sink.
The customer reports being very happy with the TECA Cold Plates—the system is cooling in about 4 minutes! The AHP-1200CP Cold Plate is an economical, easy to use product when maximum cooling is required, without a temperature controller. 120 VAC, 240 VAC and 24 VDC versions are available.
Customer plans to use the TEC unit to regulate the temperature of some electronics in an outdoor enclosure. The electronics will be mounted to a cold plate where they can be cooled by direct contact with the TEC. The walls of the enclosure will be insulated to reduce thermal losses to the outside world. The hot side of the TEC will be in a separate, ventilated part of the enclosure to carry away waste heat. Customer will provide longitudinal air flow along the heat sink, so the built-in fan will not be necessary.
Originally considered using a solid-state air conditioner to cool the entire enclosure, but now prefers the direct-contact method for lower cooling requirements and smaller size. The active load that needs to be cooled is about 50 W. It will consist of a number of RF components (amps, sources, etc) mounted to a common cold plate. Several passive components will also be mounted to the plate. The whole temperature-controlled assembly will be insulated by an inch or so of foam or something similar. The ambient temperature range is roughly 0 to 100 °F at the extremes.
Here’s another example of an AHP-1200CP thermoelectric cooler plate (Peltier cooler plate) used in a manufacturing station. The adjustable feet provide vertical flexibility in lining up the cold plate with the workstation. Parts slide easily from the hot plate to the work surface to the cold plate.
A company specializing in 3-D designs for museums, theme parks, and other attractions needed to build an “icy throne” for a museum exhibit and keep it dry at the same time.
Using four TECA AHP-1200CP Peltier cold plates (thermoelectric 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 -20 °C! Visitors to the museum can sit on the throne to feel the chill. The “ice” in the picture is not real. It is a “hard coat” of scenic ice. The throne manufacturers did not want museum visitors to get wet from real ice; their goal was to create a throne.
A customer heard about TECA’s Thermoelectric Cold Plates through word-of-mouth and placed an order within a week. The AHP-301CP Cold Plate is used in the customer’s 3D printing process. Parts are printed on an aluminum plate which is then set on the AHP-301CP Cold Plate.
As the AHP-301CP Cold Plate cools the aluminum plate, the 3D prints just pop right off of the aluminum plate. The customer is pleased with the performance, ease of use and low purchase price of this basic model.
The AHP-301CP series is replaced by the newer AHP-401CP series.
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.
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.
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.
