HEAT SINK ASSEMBLY WITH FRAME CLIP FOR FULLY ASSEMBLED ATTACHMENT TO HEAT GENERATING COMPONENT

摘要

An assembly for engaging a heat sink with an electrical component heat source includes a first retaining device with a frame that defines an opening to receive at least a portion of the heat sink and/or the heat source. The frame may be assembled with a heat sink and a retainer element arranged to resiliently bias the heat sink into contact with the heat source, and thereafter the heat sink assembly may be engaged with a heat source. A contact plate of the heat sink may be positioned into the opening of the frame from a top of the frame, i.e., inserted in a top-down direction, and the frame may be arranged for engagement with a tool to mount the fully assembled heat sink, frame and retainer element combination to the heat source.

主权项

1. A heat sink assembly including:
a heat sink having a base with a contact plate, a portion of the contact plate being arranged to contact and receive heat from a heat source; a frame having four sides defining an opening in which the portion of the contact plate of the heat sink is received, two of the sides that are opposed to each other including one or more holding features to engage with a heat source to secure the frame to the heat source, the two opposed sides each including a feature to engage with a tool to flex the two sides so as to move the one or more holding features on the two opposed sides away from each other, a top of the four sides defining a flat, continuous surface around the frame, and a bottom of the four sides defining a discontinuous surface around the frame; and a retainer element arranged to engage the frame and heat sink with the portion of the contact plate received in the opening to urge the heat sink to move downwardly relative to the frame, wherein the frame is arranged to receive the portion of the contact plate in a direction from a top of the opening to a bottom of the opening, and the heat sink, frame and retainer element are arranged for assembly together with the portion of the contact plate received in the opening of the frame and the retainer element engaged with the frame such that the assembled heat sink, frame and retainer element are engagable with a heat source.
