A heat spreader capable of adaptively adjusting heat dissipation

Abstract

The present invention discloses a heat spreader capable of adaptive heat dissipation adjustment, comprising a heating unit, a heat spreader body and a liquid cooling plate arranged in sequence from top to bottom, a condensation zone arranged in the heat spreader body, a feedback unit arranged on the heat spreader body corresponding to the condensation zone, the feedback unit comprising a feedback member and a pressure sensing sheet, a connection hole arranged on the bottom surface of the heat spreader body corresponding to the condensation zone, a groove arranged on the bottom surface of the heat spreader body corresponding to the connection hole, the feedback member arranged in the groove, a mounting groove arranged on the top surface of the liquid cooling plate corresponding to the feedback member, the pressure sensing sheet arranged in the mounting groove, the feedback member and the pressure sensing sheet abut against each other; a control valve assembly is arranged on the liquid cooling plate and is connected to the pressure sensor signal. The present invention solves the problem that the heat dissipation system cannot adapt to the dynamically changing heat load in real time by combining the pressure perception of the feedback unit with the flow rate adjustment of the liquid cooling plate.
