During production, the Qualcomm Snapdragon 810 processor was externally used for testing. The temperature is monitored by a temperature monitoring camera.

表2Table 2
由表2可以看出,实施例1~5所得相变复合材料在70℃以下没有流动性,可有效附着在待散热物体表面(如金属薄片、高通骁龙810处理器),相变复合材料在70℃以下具有吸热/放热而产生相变的特性,使其具有良好的散热功效,待散热物体表面温度和相变复合材料表面温度不会过分升高。然而,如果将相变复合材料封装在铝板中或填充于泡沫铝中(如实施例4和5所示),其散热效果反而没有将相变复合材料直接涂覆在待散热物体的表面好。因此,本发明实施例的相变复合材料更加适合直接涂覆在待散热物体的表面进行待散热物体的有效散热。It can be seen from Table 2 that the phase-change composite materials obtained in Examples 1-5 have no fluidity below 70°C, and can be effectively attached to the surface of objects to be dissipated (such as metal sheets, Qualcomm Snapdragon 810 processors), and the phase-change composite materials It has the characteristic of endothermic/exothermic phase change below 70°C, which makes it have good heat dissipation effect, and the surface temperature of the object to be radiated and the surface temperature of the phase change composite material will not rise too much. However, if the phase change composite material is packaged in an aluminum plate or filled in aluminum foam (as shown in Examples 4 and 5), the heat dissipation effect is not as good as that of directly coating the phase change composite material on the surface of the object to be dissipated. Therefore, the phase change composite material of the embodiment of the present invention is more suitable for direct coating on the surface of the object to be dissipated for effective heat dissipation of the object to be dissipated.
