Injection molding device with cooling system having carbon nanotube superfluid

Abstract

An injection molding device includes an injection unit (10), a lock unit, and a control unit. The injection unit includes a mold (11, 11′) and a cooling system. The cooling system includes one or more pipeways (18, 18′) in the mold, and a coolant received in the pipeways. The coolant is a superfluid with carbon nanotubes suspended therein. A coefficient of viscosity of the superfluid is virtually zero, therefore friction between the superfluid and the nanotubes is extremely small. This enables the nanotubes in the superfluid in the pipeways to undergo more turbulent flow, so that the nanotubes can conduct more heat from the mold. In addition, the nanotubes themselves have high thermal conductivity. Accordingly, the thermal conductivity of the cooling system is enhanced. Thus, the molten material injected into the mold can be cooled and solidified fast. This provides the injection molding device with a high molding efficiency.
