Abstract: A protective cover is used for protecting thermal conducting mediums on two heat sinks from being damaged simultaneously. The protective cover includes a plate body and two holding portions. The plate body has two opposite plate surfaces respectively covering the sides of the two heat sinks coated with a thermal conducting medium. The two holding portions are formed on the periphery of the two plate surfaces and surround the two plate surfaces to form an accommodation space respectively. The holding portions are engaged with the two heat sinks and cover the thermal conducting mediums in the accommodation space respectively.

Abstract: A thermal conductive medium cover is covered on the bottom of a heat sink for protecting a thermal conductive medium on the bottom of the heat sink, and is latched by a latching member for the heat sink. The thermal conductive medium cover includes a tray body covered on the bottom of the heat sink for protecting the thermal conductive medium, and two latched portions formed on two opposite lateral edges of the tray body. Two ends of the latching member respectively latch the two latched portions, so as to fix the tray body to the bottom of the heat sink. Thus, the thermal conductive medium cover is firmly fixed and will not fall off. Meanwhile, the latching member is also fixed and will not shake relative to the heat sink, thus preventing the latching member from colliding with the heat sink.
