LIQUID CHILLER COLD PLATE CASCADE

Liquid Chiller Cold Plate Cascade:

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.

BEVERAGE COOLER

Beverage Cooler application:

The beverage cooler application challenge was to keep concentrated beverage container located next to a hot water tank cool in a high volume OEM application. TECA has the flexibility and resources to manufacture custom OEM thermoelectric cooler (peltier coolers) assemblies intended for use as part of a customer machine, apparatus, or system. This OEM assembly is made by TECA in production runs in the thousands. It is not ours, so to protect the privacy and identity of our customers we can’t give too many details here.

This assembly is part of a beverage service product which is shipped worldwide by a well known consumer products company. TECA furnishes the cooling “engine” which refrigerates the beverage product to be dispensed, and the OEM builds finished machinery in their own plants.

BEVERAGE COOLING IN A BARREL

Beverage Cooling in a barrel:

Here’s an application that TECA’s engineering team was particularly excited about. Not because of the economics or the potential new business. Frankly we didn’t think the market was there. But as soon as they found out that a ½ barrel of beer would be needed for testing they were all over it. While none was ever sold, good lessons regarding contact methods and material stratification were learned. To see the result of the test click here.
We used an AHP-1200CP thermoelectric cold plate and a TLC-700 thermoelectric liquid chiller for testing purpose.

CRYOGENIC FLUID CONTROL

Cryogenic Fluid Control:

Cryogenic fluid is extremely sensitive to temperature and pressure changes within an experimental environment. A custom-modified version of TECA’s LHP-300CPHC Liquid-Cooled Cold Plate is installed as part of a system which allows the customer to closely monitor and control temperature.

The long life expectancy and low maintenance requirements of the LHP-300CPHC offer reliability and convenience to the customer’s long-term research experiment.

COSMETIC TREATMENT

42-tlc-700
Photofacial treatments using intense pulsed light are said to remove spider veins and age spots, but are uncomfortable for the patient. The apparatus shown uses a TECA Model TLC-700 Peltier based liquid chiller to cool the tip of the hand piece which rests on the skin area under treatment. This enhances the comfort of the patient; allowing for a better quality treatment. The chiller is a closed loop system so no water gets on the patient or the instruments. Water temperature is closely adjustable over a wide range.

PRODUCTION TESTING ( COOLING DUT)

Production testing (cooling device under test)

TECA’s RLC-1800 Rack Mounted Liquid Chiller offers powerful cooling as a component in the customer’s testing procedure. The customer, developing testing for a radar system, has a device under test (DUT) which contains cold plates. TECA’s RLC-1800 provides liquid cooling to the cold plates and prevents them from over heating during the process. The RLC-1800 is the most powerful liquid chiller we offer, with 620 watts cooling capacity.
