UPT S-2 Water Cooled Power Supply
HS – 4 Heat Station
“Lab” Oval coil
Power: 1.89 peak kW
Temperature: Spine at the end of a 3 seconds cycle – 500°F (260°C), legs at end of the 3 second cycle – 440°F (227°C).
Time: Basic simulation of a conveyor coil heat pattern – allow 450 milliseconds for ramp time – total static cycle 3 seconds.
Process and Results:
With this test, we change from a round coil to an oval coil. This allows us to focus heat differently into the “fingers’ versus the spine, in order to reduce the delta T.
The delta T for the simulated conveyor coil test was improved – 600°F differential. Based on the improved results, we see that further decoupling away from the spine is needed, in order to ensure even heating, and to further reduce the delta-T.
