Patent ID: 10986754

Abstract:
A heat-dissipating board structure and a circuit board module are provided. The heat-dissipating board structure includes a first board, a second board, a heat-transmitting layer and a buffering liquid. The first board has a first inner surface and the first inner surface has a plurality of first metal protrusions thereon. The second board is correspondingly engaged with the first board to form an accommodating chamber therebetween. The second board has a second inner surface and the second inner surface has a plurality of second metal protrusions thereon. The heat-transmitting layer is disposed in the accommodating chamber and arranged between the first metal protrusions and the second metal protrusions. The buffering liquid is filled in a residual space of the accommodating chamber. Therefore, the heat-dissipating board structure can meet the design requirements of a light-weight and thin electronic product and can effectively remove heat from a heat source.
