Abstract:
A cooling apparatus consisting of a pump (210), a pre-heater (220), a control valve (240), a condenser (320) and a reservoir (100) for a hot stamping die (10) is configured such that a refrigerant in a two-phase coexisting state of a liquid phase and a gas phase is supplied to a cooling channel formed in the hot stamping die to cool the hot stamping die using latent heat of the refrigerant. The refrigerant maintains a constant temperature in the cooling channel of the hot stamping die, which ensures uniform cooling of the hot stamping die.
