The diameter of the existing round tube is 8mm, the wall thickness is 0.15mm, the pressing thickness is 2mm, namely the thickness of the final flat tube is 2mm, the flat tube is required to bear cold and hot impact (40 ℃ below zero and 85 ℃ at high temperature), and under the test condition, the heat tube cannot bear, and bulges or pits can appear. In order to enable the pipe to bear the test, the pipe with the wall thickness of more than 0.2mm is needed to meet the requirement. However, once the tube wall is thickened, the internal passage becomes smaller, the maximum flow rate of the heat pipe becomes smaller, and performance is degraded.
