Abstract
The invention discloses a turbulent flow column based on flow field array arrangement as well as a reparation method thereof and a mold. Fused plastic is injected into an inlet at one end of an injection molding runner cavity mold of the mold; when the plastic to be fused flows out from an outlet at the other end of the injection molding runner cavity mold, the injection molding is stopped; the injection molding runner cavity mold is cooled so that the fused plastic is cooled and condensed to obtain a plastic template based on the flow field array arrangement; the plastic template is separated from the injection molding runner cavity mold; the plastic template is used as a stamping pressing head and is used for stamping metal with a low smelting point on a basic groove; and the pressing depth of the plastic template is controlled so that metal heat radiation cores based on the flow field array arrangement, which have different heights, can be obtained. The turbulent flow column is applicable to air cooling and water cooling methods and the performance is better, so that the aim of intensifying heat transferring can be realized; the heat radiation amount of a heat radiator is improved, the heat transfer coefficient is increased and the heat radiation performance is optimized; and the requirements of large-batch production can be met by a production process, the production cost is low and the machining efficiency is rapid.
