Abstract
A bearing cup structure and a thermal module thereof. The bearing cup structure includes a cup body, a base seat, an assembling member and a retainer ring. The cup body has a receiving space and a fixing section formed at one end of the cup body. The base seat is received in the receiving space. The base seat has a first shoulder section, a second shoulder section and a receiving section. The assembling member is disposed in the receiving section and passes through the receiving section. The retainer ring is attached to the first shoulder section. With the bearing cup structure, the heat dissipation performance of the thermal module is greatly promoted and the assembling time is shortened to lower the manufacturing cost.
