Bearing cup structure and thermal module thereof

摘要

A bearing cup structure and a thermal module thereof. The bearing cup structure includes a cup body and a retainer ring. The cup body has a fixing section, a receiving space and a shoulder section. The fixing section is formed at one end of the cup body. The shoulder section is formed in the receiving space. The retainer ring is formed with a hole in communication with the receiving space. With the bearing cup structure, the heat dissipation efficiency of the thermal module is increased and the assembling time is shortened to lower the manufacturing cost.

主权项

1. A bearing cup structure for assembly into a locating section of a main body of a thermal module comprising:
a main body having a round center formed with a single locating section that only partially penetrates the main body and multiple integrally formed curved radiating fins radially distributed and extending outward from said center and having the same height as the center, the locating section having an inner helical thread; a cup body having a single fixing section, a receiving space, a shoulder section and a peripheral edge, the peripheral edge being formed on and surrounding a part of an outer wall of the cup body, the fixing section being formed at one end of the cup body below the peripheral edge, the shoulder section being formed in the receiving space; the fixing section further having a circumferential outer helical thread; and a retainer ring attached to the shoulder section and formed with a hole in communication with the receiving space; wherein the retainer ring has a first side and a second side, the second side being attached to the shoulder section; and wherein the outer helical thread of the fixing section is threaded with the helical inner thread of the locating section to lock the cup body in the locating section.
