Composite casting method of aluminum cooling plate

The invention relates to a composite casting method of an aluminum cooling plate, belonging to the field of metal materials. The composite casting method comprises the following steps: fixing industrial pure aluminum or an aluminum alloy pipe which is used as a cooling liquid passageway in a mold cavity; and then fully filling liquid or semi-solid aluminum alloy melt in the mold cavity and coagulating, so as to prepare the aluminum cooling plate. By using the composite casting method, the problem that when the aluminum alloy is casted in an aluminum tube, a casting is wasted because the aluminum tube is melted and deformed is solved, thereby achieving the near-net forming of the aluminum cooling plate, reducing the consumption of materials for subsequent processing procedures and improving the production efficiency. Because the aluminum tube and an aluminum cooling plate substrate are made of aluminum materials, thereby eliminating an electrochemical corrosion phenomenon; and the aluminum cooling plate can be integrally retrained or recycled, thereby reducing the waste of the material and lowering the production cost. The total density of the casting is the same as that of an aluminum casting, thus the casting can be applied to the fields of aviation, ships and the like which have strict requirements on the weights of parts.
