NOVELTY - The utility model claims a high filling heat-conducting wave-absorbing phase change composite material, comprising a graphene frame and a phase change heat absorbing layer; a coating layer, which is set on the front part of the graphene frame; bonding layer, which is set on the rear outer side of the graphene frame; anti-sticking layer, which is set on the outer side of the back part of the said bonding a clamping column, which is connected to the right outer side of the graphene frame. the high filling heat-conducting wave-absorbing phase change composite material when the weather is cold, the water body in the heat-conducting resin layer reaches the freezing point will be expanded, the ice after expansion will push the baffle plate, which makes the baffle plate of the upper thrust can move upwards, and the baffle plate for displacement, can extrude the spring seat to make it shrink, This makes the volume of the cavity-conducting resin layer can be increased, so as to avoid the heat-conducting resin layer is damaged caused by water shrinkage, which makes the heat-conducting resin layer can be filled with more water, which is good for improving the heat storage of the device.
