Preparation method of refrigeration ceramic, refrigeration ceramic and heat dissipation device
The invention discloses a preparation method of refrigeration ceramic, the refrigeration ceramic and a heat dissipation device. The preparation method specifically comprises the following steps: S1, casting a three-component homogeneous solution composed of polyether sulfone (PES), n-methyl-2-pirolidone (NMP) and A-aluminum oxide on a flat substrate; and S2, the substrate is immersed in ethyl alcohol, the ethyl alcohol is diffused into a casting and dissolved with n-methyl-2-pirolidone (NMP), phase transformation occurs, a film rich in polymers is generated, and the anisotropic porous aluminum polymer carrying the aluminum oxide particles is formed. And S3, the casting is subjected to plasticity or printed with patterns. And S4, sintering the casting at high temperature, removing polyethersulfone (PES), and combining the aluminum oxide particles together to obtain the well-preserved cooling ceramic with the porous structure. And S5, cooling and taking out. The refrigeration ceramic is used as a heat dissipation fin of the heat dissipation device, the laser and the fluorescence conversion material are arranged in the refrigeration fin, and the water-cooling copper bar is arranged below the refrigeration fin, so that the power consumption of the fan and the water pump can be reduced.
本发明公开了一种制冷陶瓷的制备方法、制冷陶瓷及散热装置，具体包括以下步骤:S1、将聚醚砜(PES)、n‑甲基‑2‑吡罗烷酮(NMP)和A‑氧化铝组成的三组分均相溶液浇铸在平坦的衬底上。S2、将衬底浸入乙醇中，乙醇扩散到铸件中并与n‑甲基‑2‑吡罗烷酮(NMP)溶解，发生相转变，产生富含聚合物的膜，形成了携带氧化铝颗粒的各向异性多孔铝聚合物。S3、对铸件进行塑性，或印上图案。S4、将铸件高温烧结，去除聚醚砜(PES)，并使氧化铝颗粒被结合在一起，得到了具有保存完好的多孔结构的冷却陶瓷。S5、冷却取出。将制冷陶瓷作为散热装置的散热鳍，激光器及荧光转化材料设置在制冷鳍片内部，在制冷鳍片下方设置水冷铜排，可降低风扇和水泵的功耗。
