Abstract: An expandable power connector comprises a frame, a power connector disposed on the frame, and a plurality of module sets lodged in the frame. Wherein, when the module sets are assembled to the frame, a polygonal expandable power connector is contributed. Accordingly, the number of sockets on each module set can be properly arranged. Applicable space between the adjacent sockets is also increased for bulky plugs. Due to the design that each module set with at least one socket is lodged in the frame, a new module set can substitute for the old module set while the socket thereon malfunctions. Therefore, the present invention promotes the convenience of using and maintenance.

Abstract: The present invention pertains to a radiator comprising a base body and a plurality of protruding fins outward extended from the base body. Wherein, each protruding fin is densely structured by a plurality of stacked fin pellets in company with apertures defined therebetween. Whereby, the fin pellets conduce to expand the surface area of the protruding fins to assist the communication of the outer air therebetween, so as to promote the heat dissipation of the radiator.
