Leakage Test  100%

The water pressure test is to detect whether the liquid cooling plate is leaking by immersing it in water and pressurizing it to observe whether bubbles emerge. During the test, pay attention to controlling the water pressure to avoid damage to the liquid cooling plate caused by excessive water pressure. At the same time, pay attention to releasing air from various interfaces of the liquid cooling plate to avoid misjudgment caused by increased pressure.

Precautions for liquid cooling plate leakage test

1. Before conducting a liquid cooling plate leakage test, ensure the safety of the test equipment and test environment to avoid accidents.

2. Different test methods and test pressures should be selected for different models of liquid cooling plates.

3. During the test, pay attention to the sealing of each interface of the liquid cooling plate, and pay attention to the protection of the oxidation anti-corrosion coating.

4. After the test, the test equipment and test environment should be cleaned in time to avoid contamination.

Thermal Simulation Design

‌Thermal simulation design‌

It refers to the technology of predicting and analyzing the temperature distribution, heat flow conduction, thermal stress and other parameters of an object in different thermal environments through computer simulation. This technology can help engineers predict the thermal problems that may occur during actual use during the design stage, so as to optimize in advance and improve the performance and reliability of the product‌.

Flow resistance test, water cooling plate joint welding strength test

Flow resistance test:
The water-cooling plate is connected to the flow tester, the coolant temperature (℃), flow (L/min), observe and record the inlet and outlet pressure values ​​of the water-cooling plate, and obtain the inlet and outlet pressure loss of the water-cooling plate.

Water-cooling plate joint welding strength test:
The water-cooling plate is fixed on the test bench, a hole is drilled on the aluminum joint, and the pull-out force test hook is hooked on the joint hole for testing. The joint welding is required to resist the pull-out force test.

The buried copper tube water-cooled plate refers to a water-cooled plate that is made by CNC milling an aluminum base plate and embedding a copper tube in it. The bent copper tube is then riveted onto the aluminum base plate with a hydraulic press, and then processed into a water-cooled plate. The high thermal conductivity of the copper tube is used to take away the heat, and the heat is transferred from the heating element to the coolant, thereby achieving heat dissipation.

Brazed water-cooled plate refers to a water-cooled plate that is assembled with a base plate and a cover plate and then heated in a vacuum chamber. Under corresponding process conditions, the brazing material is melted to connect the base plate and the cover plate into a whole and form a flow channel inside.

‌The deep  drilling water cooling plate is a heat dissipation method that uses fluid cooling. It is a water cooling plate that uses deep hole drilling technology to drill multiple deep holes on the heat dissipation plate and welds them at both ends to form a flow channel circulation, allowing water to flow through the pipes to take away the heat.
