Intruduction
The customer provides a general size, but it needs to be round. Besides, the fin sheet of the radiator needs to be round in shape, which should be due to natural convection. The circular radiation efficiency is the highest. Our engineers did CFD analysis based on this model and finally optimized a natural convection scheme
The Thermal Solution
Designed requirements
Power1 :8*8W+40w=104W;
Aluminum Material
Cold forging process
No fan and Normal convection
Environment 40℃
Simplified model and heat source in the Ansys software
Parameter setting and meshing are in the software
To solve the function calculation equation, make each curve function equation convergent based on the set parameters
After calculation, the temperature distribution diagram of the heat source within the range of the set module is obtained, and then the engineer can optimize it.
Results
Our engineers use detailed data and accurate meshing CFD software for calculation. By constantly adjusting the data module, heat pipe position, and thickness and spacing of heat sinks fins, we finally designed a heat sink scheme meeting the requirements for the customer. Meanwhile, we have made sample testing and mass production. However, the heat pipe heat sink should be noted that in extreme environment, the liquid inside the heat pipe is easy to freeze and then expand. Used the simple model method, the result will be different from the actual module. The heat sink surface Max temperature is 94.17℃
