The reversible mortise lock of the present invention can be installed on either the left or right side edges of a door opposite the door hinges. The lock includes a housing with a live bolt pivotally and slidably mounted in the housing. The live bolt slides between an extended position beyond the housing and a fully retracted position within the housing. When fully retracted, the live bolt can be rotated 180&#xb0; so that the beveled face of the live bolt can be reversed. A finger pivotally mounted within the housing blocks full retraction of the live bolt when the mortise lock is installed in the door.

A grease protecting apparatus () includes a heat sink () defining a plurality of receiving cavities () therein, a layer of grease () spread on a surface () of the heat sink, and a grease cover () attached to the surface of the heat sink for protecting the grease from contamination. The cover includes a main body () defining a protecting space () therein for covering the grease, two wings () extending from two opposite sides of the main body, and a plurality of projections () extending from the wings for being snapped in the receiving cavities of the heat sink. The projection has a trapezium-shaped cross section.

A heat dissipation device includes a fin unit (), and at least a heat pipe () including an evaporating section () and at least a condensing section () extending through the fin unit. The fin unit includes a plurality of fins stacked together. Each fin comprises a wavy and a V-shaped section () and a planar section () therebetween. The wavy and V-shaped sections of the fins can guide an airflow flowing into the fin unit to smoothly flow therethrough, and prevent escape of the airflow from lateral directions of the fin unit. Furthermore, the wavy and V-shaped sections increase the heat dissipation area of the fins and strengthen the fins.
