How to Distinguish the Design Advantages and Disadvantages of Liquid Cold Plate
Many customers want to know how to identify the quality of the Liquid cold plate, which is very important. We can briefly talk about some related knowledge.
The flow rate for the Liquid cold plate determines the pipe diameter. Generally speaking, the flow resistance will be significant if the flow rate is too large. And if the flow rate is too low, the pipe material will be well-spent. The customer generally determines the inner diameter of the water inlet and outlet of the liquid cold plate. Because it must match the customer interface. The practical design and selection of the internal flow channel of the liquid cold dish is the place that most test the design engineer's technical level.
Brief description of the design and selection of the inner flow channel of the water cooling plate.
(1) The runners' series-parallel structure and size design should consider the customer's requirements for the temperature uniformity of the water-cooled plate. In contrast, the series connection should consider the temperature rise, flow resistance, etc. And the parallel connection should consider the split flow uniformity and temperature rise.
(2) Considering the customer's restriction on the flow resistance of the water-cooled plate, some simple manual calculation results of the flow channel are more accurate.
(3) The difference in manufacturing cost of different runner forms must be considered, and the mass production cost is essential.
(4) Mechanical strength.
(5) Processing technology:Brazing
(6) Manufacturing costs.
How to distinguish the quality of the water cooling plate
We can use some simple tools to identify mass-produced water-cooling plates. The following method only works well with individually purchased radiators.
From the material point of view, the water-cooled plates on the market are designed with aluminum plates embedded with copper tubes. This water-cooling plate is made of aluminum and copper alloy, which is very cost-effective. The quality of aluminum and copper depends on whether there are impurities, that is, the quality of raw materials.
According to the process, the materials can be the same, but the process is different. However, the effect of the radiator is different. The process should be viewed from two aspects. One is whether the production is carried out according to the design drawings. The other is the parameters marked in the pictures should be checked with corresponding measuring tools.
According to the quality of the water-cooled plate, there will be adhesion problems while embedding the copper tube into the aluminum plate. If there is a gap between the two, it will affect the heat dissipation effect and even cause water leakage. In addition, the copper tube and the aluminum plate are connected by a buried tube process and then processed by a grinding or flying surface process. Therefore, the entire water-cooled plate forms a plane. Good or bad can also be judged from this plane to see if it is flat. Whether the copper tube and the aluminum plate are fused into a plane, or there are gaps or unevenness will affect the heat dissipation effect.
From the performance point of view, the data is obtained by testing the simulation software. Checking the data on the machine, comparing the data, and checking whether the results meet the design requirements.
The design advantages and disadvantages of the water cooling plate can be roughly judged through several aspects. If the requirements are higher, you can ask Winshare for the measured data of heat dissipation. It is more accurate to judge by data.
