When a radiator needs to undergo DV or PV testing, it’s usually necessary to calculate the test time for all test items in the test list. How long does a coolant pressure test take? This is a very important test time. In the following blog post, I’ll use a battery cooling plate as an example to explain step by step.
1.How does a coolant pressure test work
In my previous blog post, I presented actual pressure drop data from battery cooling plate tests, including the test steps. If you’re interested, you can also read the blog post on calculating pressure drop, where the data supports the underlying principles.
2.Time cost for the product connection
In our test lab, we will use quick connector for the radiator connection with bench. That will only takes 0.5h to complete this step.
3.Vacuuming time for coolant pressure test
Before testing, the product needs to be vacuumed. It will take around 0.5h.
4.Time for coolant temperature stablize
How long does a coolant system pressure test take will mostly depend on the temperature achieve to specific temperature, the tolerance is ±1℃. It will also takes 2h roughly.
5.Time for pressure hold and flow stable
How long should a coolant pressure test hold pressure? Base on my experience, 1min is enough if the pressure doesn’t change within ±1kpa.
How long does it take to pressure test a radiator or battery cooling plate?For the flow stalbe,also 1min is ok.
6.Total time sum for the pressure loss test
Base on above test steps, the total times for coolant pressure drop test is 0.5+0.5+5+0.5=6.5h.That is say, half day is enough for the coolant pressure test.
