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
Portable medicine cooler needed for carrying emergency intravenous solutions, all components must be enclosed within the case. TECA designed a custom thermoelectric (peltier) based cold plate built into a Pelican™ Box.
TECA is developing this product for a new customer. We have taken a standard Pelican™ Box and configured a battery powered thermoelectric cooling system which is installed totally inside. This cooled box is for the purpose of transporting up to 4 liters of emergency intravenous solutions safely.
There are fitted compartments inside as well for transporting other necessary items for patient care. Since nothing is exposed or protruding from the box, our customer has ended up with a good looking and very rugged, functional thermoelectric product.
At a prominent U.S. university, neuroscience research team choose TECA’s economical AHP-270CP Cold Plate.
The customer reports: “We cool a fly to 8 deg Celsius, and also use vacuum to attach it to the device during a brain dissection procedure. Essentially, the cooling is anesthetizing the fly, making it possible to attach the fly to the dissecting chamber in a very precise manner, using a manipulator (also in the picture).” The AHP-270CP is a great solution because it is small, inexpensive and yet offers reliable and effective cooling on the bench top.
A European company specializing in equipment for the continuous flow chemistry market required extreme temperatures for a new product. Integrating a customized version of TECA’s Liquid Cooled Cascaded Cold Plate made the customer’s product possible: they are able to reach temperatures from minus 70 °C to plus 80 °C.
The customer reports that their new continuous flow reactor allows for the use of flow chemistry in many applications, achieving quicker results safely and with better control.
We used TECA’s AHP-1200CAS three stage cascaded thermoelectric cold plate system to facilitate dissection of frozen human postmortem brain slices for extraction of protein for Proteomics research. Because we were trying to select specific regions without damaging the rest of each small specimen, it was important for us to maintain the integrity of the specimen during dissection.
Working in a lab at normal room temperature, we found that a constant temperature of -18 °C was ideal for this work (-20 °C was too cold, and warmer than -18 °C made the tissue start to melt). It would have been impossible to maintain such a precise temperature outside of a Cryostat without the cold table. It was immensely easier to perform the dissection on the cold table, and of course also much easier to wipe down the cold table than to clean a Cryostat.
To meet an Aerospace manufacturing customer requirement TECA sales and engineering team modified a standard model chiller to meet a highly specialized demand of the application, including liquid cooling, 24 VDC input and wall mounting. This recirculating liquid chiller was developed for a customer who needed something similar to the TECA LHP-300CP chiller; but it had to be a liquid cooled liquid chiller – it had to be 24 VDC input – and it had to be mounted on the wall!
The application is X-Ray inspection of aircraft engine parts. Temperature controlled water is circulated through a heat exchanger which is keeping photo diodes nice and cool, assuring quality X-Ray imaging.
Here’s another custom military application by TECA.
The United State Navy needed a liquid chiller to circulate coolant and also meet strict military requirements. TECA developed a custom thermoelectric liquid chiller using MIL rated components. This is a liquid chiller for circulating chilled coolant as part of a tracking system on a NAVY ship.
Note that the chilled liquid circuit is effectively “sandwiched“ between two heat sinks with rugged Mil 901 fans. Wiring and electrics are housed in a NEMA-4X/Harsh Environment enclosure with an O-ring gasket seal. This unit is rated for shipboard use in salt-spray, shock and vibration.
The customer needed a compact thermoelectric cooling system to cool flow of fluid through removable membrane liquid jacket used in a mobile medical application. TECA’s sales and engineering team worked with the customer and developed the product you see in the pictures above for the exclusive use of our customer.
The application is medical and will be protected by patent. Thermoelectric cooling will be employed for effective cooling of the brain for emergency treatment of stroke victims.
Here’s more of the engineers dream test job (beverage cooling). The team was messing around and decided to cool a keg with a TLC-700 liquid chiller and one of our medical customers water pads used for patient temperature therapy. Instead of the patient laying down on the pad they wrapped it around the keg and then insulated it.
Not quite an economical way of cooling your beer. But they did use the mattress the next day to sleep off the hangovers.
A customer wanted a TLC-1400 thermoelectric liquid chiller (Peltier chiller) to maintain a 400 watt load under normal conditions except for one thing, the hose needed to be over 200’ long. Would it pump? How much of an effect would it have on the cooling capacity? We could have run the numbers and come up with an estimate.
It was really easier to just hook up some hose and a constant load plate, roll it into the environmental chamber and see what it did. It did more than it was supposed to. The customers safely bought it knowing it would do what he needed.
