Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat pipe processing, and in particular to a degassing mechanism for the inlet pipe of a copper tube capillary structure sintering device. Background Technology
[0002] As electronic products become increasingly advanced, with more sophisticated manufacturing processes, smaller sizes, and higher power outputs, the heat generated by these products is increasing. This necessitates sufficiently small heat dissipation structures with high heat dissipation efficiency. Currently, to improve heat dissipation efficiency, capillary structures with good thermal conductivity are often added to heat spreaders and heat pipes to enhance thermal conductivity and thus improve heat dissipation.
[0003] The capillary structure inside existing copper tubes is mainly formed by sintering copper powder. Such a processing process generally requires about 8 hours. During this process, nitrogen is introduced as a protective gas to prevent copper oxidation. However, since some oxygen remains even after venting, and oxygen is also present in the nitrogen gas that is actually introduced, hydrogen is often mixed into the nitrogen gas. The small amount of oxidized copper is reduced through a reduction reaction. In other words, a nitrogen-hydrogen mixture is continuously introduced during this processing time.
[0004] However, even so, some capillary structures will still be oxidized, reducing the overall yield. To solve this problem, one approach is to address the issue at its source, which involves purifying the input hydrogen-oxygen mixture by consuming the internal oxygen during the input process, thereby reducing the oxygen content in the hydrogen-oxygen mixture. Another approach is to use other structures as consumables during the sintering process to replace the capillary structures in reacting with oxygen, thereby minimizing the oxidation of the capillary structures and improving the yield.

This mechanism removes oxygen from the nitrogen-hydrogen mixture by setting the degassing mechanism inside the inlet pipe of the copper tube capillary structure sintering device and by using iron and charcoal set inside the degassing mechanism. This reduces the oxygen content in the copper tube capillary structure sintering device and improves the yield.
