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.
They manufacture navigation devices for land, road, trail and water and they needed to evaluate circuit boards @ various temperatures (-30 °C to -40 °C, no or minimal heat load, room temperature ambient) and on recommendation of a person who joined them from a controls company and had been using the solid state cold plate AHP-1200CAS. The system required the cold plate, cascade, cascade control and tapped plate. The tapped plate is built into the cold plate in place of a smooth plate surface to attach to the cascade plate.
The cascade control facilitates power and temperature control to the cascade. The system also included an acrylic cover and insulation block. They received the system and liked how it is built.
Customer uses TECA AHP-1200CPV cold plate for a very accurate temperature control of a transmitter. The temperature of the unit under test is always the same, no matter what power it dissipates.
The thermal control loop works great and there is never a problem going cold or hot or switching power on or off.
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 technological university in Asia chose TECA’ s thermoelectric cooling Model AHP-800MSP Magnetic Stirring Cold/Hot Plate to anodize aluminum. The researcher’s process required a temperature of 10 °C.
The AHP-800MSP‘s universal input voltage feature (100-240 VAC) allows it to be used anywhere, making it a perfect, off the shelf choice for our customer in Asia. He wrote to us: “It is quite good. Also the manual is quite clear and quite user-friendly. Thank you.”
Unique to this product is the adjustable nature of many of its features: stir-bar speed, fan speed (for noise reduction), temperature sensing (internal or external) and more.
The AHP-800MSP can even accept beakers of various size by adding optional sleeves. The solid-state thermoelectric construction is low-maintenance. There are no filters to change and no moving parts except for the fans. Our products use robust thermoelectric modules and boast a long service life.
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.
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.
A branch of the US military had an overheating problem with a high-tech radio inside the wing of a fighter aircraft. TECA developed a custom, high-performance cold plate that withstand the shock, vibration, and G forces created by one of the most technically advanced aircraft.
In order to assure maximum strength with minimum weight, TECA’s Advanced Machining Center machines the finned heat sinks for each cooler from a single blocks of material
Here are pictures of the TLC-900 thermoelectric liquid chiller with LHP-150CP Peltier liquid cooled cold plate set up run in the lab. The “load” is a plate with 10 power resistors mounted to the top and a series of thermocouples measuring the surface of the LHP-150CP’s thermoelectric cold plate.
During the test the power to the resistors is increased in steps with enough time in between for the temperatures to stabilize. Plotting the data resulted in performance curves. The test was made with the load insulated and with the load simply covered.
Later on we used a TLC-900CAS, a version of the TLC-900 made specifically for running and controlling secondary cold plates like the LHP-150CP and ran some step, ramp and soak profiles.
