Inflatable Vapor Chamber

Air leak testing

1) Fill the test piece with dry compressed air to

205kPa±5kPa

2)hold pressure for 120s.

Pressure Cycle Test

 Initial Condition:

The test is filled with aqueous ethylene and glycol solution, then keeping the liquid and ambient temperature are the same

Inlet Pressure Fluctuation:

1) 50kPa→200kPa→50kPa→200kPa

2) 200kPa→50kPa→200kPa

 the Pulse Frequency:

1Hz±0.5Hz

 The Cycle:

1) 90,000 times when 80℃

2) 10,000 times when -20℃

Burst Pressure Test

Fill the test piece with water, pressurise

100kPa at a time and hold pressure for 60s,

pressurise to a maximum of 800kPa.

Temp Cycle Test

 Initial Condition:

Apply pressure on the test piece to make the

pressure reaches 205kPa

 Temperature Fluctuation

the ambient and aqueous solution of ethylene glycol Temperature 80℃→-40℃→80℃→-40℃.

The Cycle:

Regular change, cycle 300 times

Flatness Test

Salt Spray Test

 Initial Condition:

1) 50g/L sodium chloride solution

2) The pH value: 6.5 - 7.5

3) temperature of the test chamber: 35℃±2℃

4) temperature of the solution: 47℃±2℃

 Testing Procedure:

Spray continuously for 30min, then keep standing

for 90min

 The Cycle:

Regular change, cycle 300 times

Vacuum Test

Testing Procedure

1) Withdraw the air inside the specimen

2) The absolute pressure inside the test spciemen shall be reduced To 3kPa in 30 minutes.

Corrosion Test

 Testing Procedure
1) Mix 1 liter of distilled water with 148 mg of sodium sulphate, 1320 mg of sodium chloride, and 138 mg of sodium bisulphate to form a corrosive solution.

2) Mix the aqueous ethylene glycol solution and the corrosive solution in 1:1 ratio.
3) mix the resulting solution at a volume ratio of 40% ethylene glycol solution to 60% to form the final mixed solution.

4) Operate the internal corrosion test device at a temperature of 90°C.
5) Set the flow rate to between 5L - 30L / min.

 The Cycle

1)  Duration: Run the test device for 76 hours continuously.

2) Interruption: Stop the device for 8 hours after every 76-hour run.

3) Repetition: Repeat the above cycle 14 times.
