Patent number: 8908373Abstract: A metal plate that forms a heat-absorbing surface has a center portion which protrudes so as to correspond to the size of a semiconductor element. A fixing support point of a plate spring is provided at a center of this protruding surface, and the plate spring is fixed on all sides. Grounding pressure is applied via the single point provided by the fixing support point. As a result, any tilting of the heat-absorbing surface relative to the surface of the heat-generating element is kept to a minimum. Heat pipes are provided around the periphery such that they enclose the protruding area from the outside.Type: GrantFiled: September 16, 2010Date of Patent: December 9, 2014Assignee: NEC CorporationInventors: Hitoshi Sakamoto, Chenpin Hsu
