The second particles are aluminum-silicon alloy particles, wherein the silicon content is 3-10%, the particle size of the second particles is 100-: 1-10: 1. in this embodiment, the second particulate matter with a small melting point is mixed with the first particulate matter with a large melting point, and after brazing, the second particulate matter is connected between the first particulate matter and the inner wall of the closed cavity to form a capillary structure. In particular, the capillary structure 5 formed in this embodiment has a larger surface porosity at the inner wall far from the sealed cavity 4, and a smaller bottom porosity at the inner wall near the sealed cavity 4, so that it has a better capillary liquid absorption capacity.
The existing copper soaking plate adopts a copper powder sintering process, and the porosity of a sintering layer is 30-50%; in the sintered layer in the embodiment, the porosity of the bottom layer is 20-40%, and the porosity of the surface layer is 30-70%, so that the capillary structure is more beneficial to the backflow of condensate.
