Liquid cold plate, is a component that exchanges heat through the flow of coolant;
The principle is to process one or more flow channels on a metal plate, install electronic components on the surface of the plate (coated with heat conduction medium in the middle), and the coolant flows in from the inlet of the plate and out from the outlet, thereby taking away the heat of the components. The common processes for water-cooled plate flow channels include friction welding, vacuum brazing, buried copper pipes, drilling, etc.
Water cooled plate heat exchangers bring significant cooling effects to products that require cooling, and are deeply loved by major manufacturers. They continue to increase their research and development efforts to improve performance.
However, there is also an important issue with water cooling heat sink plate, which is how to maintain their sealing, as if coolant leakage occurs, it can cause damage to the product, which will make the economic losses, and even major accidents.
Therefore, strengthening the finished product inspection of liquid nitrogen cooling plate and ensuring their quality has become a top priority for major manufacturers.
Conventional quality testing for liquid nitrogen cooling plate includes air tightness testing and explosion testing. The airtightness test is generally divided into helium test or water test, which are two methods that are convenient for detecting the airtightness of water cooled plates; The disadvantage is that potential hidden defects cannot be detected.
Explosive testing refers to sampling and conducting explosive testing in finished products to measure whether there are defects such as solder joints, over soldering, or penetration; The disadvantage is that it is not possible to test all products.
Conventional quality testing methods have certain limitations. How can we conveniently and quickly conduct quality testing on liquid cold plates? Awind has provided a phased array water immersion automation detection solution for liquid cooling plate heat exchanger, contributing to the quality inspection of liquid cooling plate heat exchanger.
