[0002] Transistors are important components of circuit chips, and each transistor is a unit of a transistor. The transistor itself is like a switch, and the output voltage can be determined by controlling the switch. The number of transistors ranges from hundreds of millions to tens of billions. Each transistor only contributes a very small amount of power consumption and heat, but the overall value will be a terrifying number. When the current passes through the transistor, it will release a part of the heat, just like an electric heater in life. At the same time, due to the fact that the heat dissipation speed is far less than the generation speed, a local high temperature area is formed. It should be pointed out that for most transistors, even if the heat is high, it occurs in a local area to a large extent, so the heat dissipation problem of the transistor is also a problem that people need to solve urgently.

After the bearing table 10 is circulated on the upper conveying assembly 51 to complete the function operation of the modules, the bearing table 10 is conveyed to the lower conveying assembly 52, so that the bearing table 10 can reciprocate on the upper conveying assembly 51 and the lower conveying assembly 52 to flow, thereby improving the utilization rate of the bearing table 10, reducing manual operation and improving production efficiency.

[0048] Referring to Figure 9 and Figure 10, further, the single crystal nut-free heat sink 12 assembly lock screw flexible line body further comprises a front lifting module 60 located upstream of the heat sink module 20 and a rear lifting module 70 located downstream of the locking module 40, the front lifting module is used to transport the carrying table 10 located in the lower conveying assembly 52 to the upper conveying assembly 51, and the rear lifting module is used to transport the carrying table 10 located in the upper conveying assembly 51 to the lower conveying assembly 52, so that the carrying table 10 can be reused.
