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.

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.

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.
