AEROSPACE MANUFACTURING

Aerospace Manufacturing:

liquid chiller for aerospace manufacturing application

 

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.

CUSTOM MILITARY LIQUID CHILLER

Military Liquid chiller:

Here’s another custom military application by TECA.

Military grade liquid chiller

 

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 enclosure with an O-ring gasket seal. This unit is rated for shipboard use in salt-spray, shock and vibration.

CALIBRATION

Calibration:

calibration using TLC-1200HC liquid chiller calibration with liquid chiller

 

A commercial laboratory uses TECA Chiller TLC-1200HC to discourage temperature gradients in a calibration system. Utilizing the built in temperature controller, the customer was able to successfully run the input and output to a temperature difference of zero. Designing a suitable calibration method was critical to the customer’s ability to release a new product to market.

The photos here illustrate the compact size of TECA’s TLC-1200HC.

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.

SEMICONDUCTORS

Cooling Semiconductors:

semiconductors

 

A research oriented organization uses TECA’s TLC-900 recirculating liquid chiller to control the temperature of a semiconductors test stage where proximity of TEC would produce electromagnetic noise hard to screen.

Temperature controlled fluid supplied by TLC-900 keeps their test stage cooled and free of noise.

AIRBORNE THERMOELECTRIC LIQUID CHILLER

A customer serving the national security market specializes in remote sensing solutions. TECA Corporation’s thermoelectric, rack-mounted RLC-1400 Liquid Chiller improves the customer’s product efficiency by reliably cooling a laser and high-power electrical components, as part of an airborne system.

PRODUCTION TESTING ( COOLING DUT)

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.

COOLING DETECTORS FOR PIPELINE INSPECTION

Cooling Detectors For Pipeline Inspection:

The maintenance supervisor from an inspection company was experiencing over heating of his detectors which are used in his outdoor pipeline inspection process. TECA’s TLC-900 Liquid Chiller was mounted to the back of his truck to aid in cooling two detectors. The components had been close to over heating without the chiller. Using the chiller with 50 feet of hose, the customer obtained a good result, successfully cooling his components down several degrees (Celsius), to a safer and more reliable operating temperature.

The customer has purchased multiple TLC-900 Chillers for the same use in other trucks. With little maintenance required, the TLC-900 has versatile features such as universal input (100-240 VAC), which is helpful in this application as the customer has inspections in Europe and in the USA. The same TLC-900 Chiller can be used in either locale. A PWM temperature controller offers USB communications, programmable ramp & soak profiles, and fan speed control for noise reduction.
