Abstract:
A cooling unit for cooling a heat-generating component, comprising:a first heat sink overlapping the heat-generating component and thermally connected thereto, said first heat sink having a plurality of projections, each projection extending away from the heat-generating component and having a distal end remote from the heat-generating component;a second heat sink covering the first heat sink, having a plurality of through holes in which the projections are inserted, each projection extending through a corresponding through hole and having the distal end protruding outward from the second heat sink, said second heat sink being so positioned that a first gap is provided between the first heat sink and the second heat sink and a second gap is provided between each projection and the corresponding through hole receiving the projection and communicating with the first gap; anda heat-conducting medium filled in the first gap and the second gap, being semi-solid material having a viscosity and thermally connecting the first heat sink and the second heat sink.
