The base assembly has an array of fins. Magnets are received in holders of the base assembly and are magnetically bondable to an underlying metal attachment member so that the array of fins is in thermal communication with the member. Heat in the vicinity of the member is conducted to the fins and dissipated from the fins into the ambient environment. ## Claims ### Claim 1 A magnetic heat sink device having a longitudinal axis comprising: a base assembly comprising a plurality of magnets, a base having a periphery disposed radially outwardly from the longitudinal axis and defining a plurality of holders sized to receive said magnets disposed adjacent said periphery, and a baseplate having a bottom surface disposed axially proximate a said magnet, wherein said bottom surface defines a plane oriented generally perpendicular to the longitudinal axis, and an array of fins in thermal communication with said base, so that heat applied to said base is conducted to said fins and dissipated therefrom into the ambient environment; and a handle extending in upright fashion from said base. ### Claim 2 (depends on 1) The magnetic heat sink device of claim 1 wherein said base assembly is generally symmetric about the longitudinal axis and said handle extends from said base assembly in a direction generally parallel with the longitudinal axis. ### Claim 3 (depends on 1) The magnetic heat sink device of claim 1 wherein said array of fins is generally symmetric about the longitudinal axis. ### Claim 4 (depends on 3) The magnetic heat sink device of claim 3 wherein said handle is coaxial with the longitudinal axis. ### Claim 5 (depends on 1) The magnetic heat sink device of claim 1 wherein said base is generally cylindrical and has a plurality of resilient arms defining a handle retention pocket coaxial with the longitudinal axis, said holders are generally cylindrical sockets having an axial socket wall which projects upwardly from said base, said socket wall is castellated, and a plurality of inserts are configured to engage an interior surface of said socket such that each of said magnets is contained intermediate a said socket and a said insert. ### Claim 6 (depends on 1) The magnetic heat sink device of claim 1 wherein said array of fins comprises a first set of fins and an alternating second set of fins. ### Claim 7 (depends on 6) The magnetic heat sink device of claim 6 wherein said first set of fins comprises a plurality of identical equiangularly spaced fins which project radially beyond a periphery of said interrupted annular portion, and an annular portion projecting radially away from and flaring slightly angularly away from a periphery of said baseplate, said annular portion interrupted by a portion of said first set of fins generally contiguous with said baseplate. ### Claim 8 (depends on 7) The magnetic heat sink device of claim 7 wherein said first set of fins taper from a bottom portion to an upper portion generally convergent toward said handle, wherein said annular portion is interrupted by said bottom portion of said first set of fins, and said bottom portion is radially inwardly contiguous with said baseplate periphery. ### Claim 9 (depends on 6) The magnetic heat sink device of claim 6 wherein said second set of fins comprises a plurality of identical equiangularly spaced fins having a smaller surface area than said first set of fins. ### Claim 10 (depends on 9) The magnetic heat sink device of claim 9 wherein said array of fins includes an annular shoulder sized and configured to envelop said holders and said magnets, and said second set of fins project radially from said annular shoulder to a radial periphery of said interrupted annular portion and axially from said interrupted annular portion to an upper fin shoulder contiguous with said annular shoulder. ### Claim 11 (depends on 1) The magnetic heat sink device of claim 1 wherein said array of fins is composed of heat conductive plastic material. ### Claim 12 A magnetic heat sink device for removing heat from a metal member and having a longitudinal axis comprising: a base assembly comprising: a base having a periphery disposed radially outwardly from said longitudinal axis, a plurality of holders defined adjacent said periphery, and a base plate defining a plane oriented generally perpendicular to the longitudinal axis, a magnet received in each of said holders and magnetically bondable with said member, and an array of fins in thermal communication with said base received at said base plate is conducted to said fins and dissipated therefrom into the ambient environment; and a handle extending in upright fashion relative to said base assembly. ### Claim 13 (depends on 12) The magnetic heat sink device of claim 12 wherein said base is generally symmetric about the longitudinal axis and said handle extends from said base in a direction generally parallel with the longitudinal axis. ### Claim 14 (depends on 12) The magnetic heat sink device of claim 12 wherein said array of fins is generally symmetric about the longitudinal axis. ### Claim 15 (depends on 14) The magnetic heat sink device of claim 14 wherein said handle is coaxial with the longitudinal axis. ### Claim 16 A method of attaching a membrane to an underlying upper surface of a metallic attachment member having a heat activated adhesive comprising: positioning an induction tool above the membrane and metallic member; heating the member via the induction tool to activate the adhesive; removing the induction tool from the vicinity of the member; positioning a heat sink device over the member; magnetically bonding the device to the member; and removing heat from the member through the device into the ambient environment. ### Claim 17 (depends on 16) The method of claim 16 further comprising providing an array of fins on said heat sink device and establishing a thermal path between the attachment member and fins. ### Claim 18 (depends on 16) The method of claim 16 further comprising establishing a plurality of magnetic bonds between the heat sink device and the attachment member. ### Claim 19 (depends on 16) The method of claim 16 wherein the step of positioning the heat sink device further comprises using a handle to manually position the heat sink device. ### Claim 20 (depends on 16) The method of claim 16 further comprising substantially centering the heat sink device relative to the attachment member.
