[0002] A molecular pump is a high-vacuum pump that uses a high-speed rotating rotor to generate a strong centrifugal force to suck gas molecules from the inlet of the pump to the outlet, thereby achieving the purpose of pumping vacuum. Molecular pumps are usually used in scientific research and industrial applications that require extremely high vacuum levels, such as particle accelerators, semiconductor manufacturing, mass spectrometry, surface science experiments, etc. A molecular pump power supply refers to a power supply device that provides the electrical energy required for the operation of the molecular pump.

With the cooperation of multiple thermal conductive silicone gels, the heat transfer is accelerated, and finally the heat is dissipated into the air through the metal aluminum, achieving a good heat dissipation effect.

[0038] Working principle: The utility model is an integrated dedicated molecular pump power supply. When in use, the fixing bolt 902 with a spring 901 is screwed tightly at the installation position. With the cooperation of the spring 901 and the fixing bolt 902, the connection position is further strengthened to prevent loosening caused by vibration. At the same time, the internal heat is conducted by the lower heat dissipation plate 203, and then conducted into the interiors of multiple heat conduction blocks 202. Due to the hollow shape between the upper heat dissipation plate 201 and the lower heat dissipation plate 203, the heat transfer is accelerated. Finally, the heat is dissipated through the upper heat dissipation plate 201 to achieve a good heat dissipation effect. The external air is accelerated into the interior by the intake fan 14 inside. During the intake process, the impurities and dust inside are filtered by the dust-proof net 1108 to reduce the dust entering the interior of the housing 1. After using for a period of time, by rotating the knob 1101, the second bevel gear 1107 at the rear end of the knob 1101 meshes with the first bevel gear 1106 on the side wall of the cage 1104, thereby driving the upper first reel 1105 to wind up, and rolling up the used dust-proof net 1108. Since both ends of the first reel 1105 are rotatably connected to the two cages 1104 respectively, and because one end of the first bevel gear 1106 penetrates the side wall of a cage 1104, when installing, one end of the first reel 1105 is directly connected to one end of the first bevel gear 1106, so it can drive it to rotate. The unused dust-proof net 1108 is replaced to the original position to achieve continuous use. After the whole roll is used up, the internal second reel 1109 and the first reel 1105 can be replaced by removing the protection plate 1103. When disassembling, the first reel 1105 is moved towards one cage 1104, and then the sleeve on one end of the first bevel gear 1106 is removed. After the removal is completed, the other end is removed, reducing the frequency of cleaning and maintenance.
