Abstract:
A defroster and vehicle are provided. The defroster includes: a housing (5) defining an air outlet (4), a heating device disposed in the housing (5), an air blower (1) defining a blowing outlet (11) and disposed in the housing (5), and an air duct (2) defining a duct inlet (22) and a duct outlet (23), the air duct (2) being disposed between the blowing outlet (11) and the heating device so that air blown out from the blower outlet (11) enters the air duct (2) via the duct inlet (22) and goes out of the air duct (2) via the duct outlet (23), then passes through the heating device to exchange heat with the heating device, and is discharged out of the housing (5) via the air outlet (4), wherein the area of the duct inlet (22) is different from that of the duct outlet (23).
Abstract:
A metal forming apparatus (1000) includes a smelting device (5), a molding device (10), an injection device (8) and a vacuumizing device (3). The smelting device (5) defines a smelting chamber (501), and includes a rotatable crucible (502) and a heating unit (003) both disposed within the smelting chamber (501). The molding device (10) defines a molding chamber sealedly communicated with the smelting chamber (501). The injection device (8) includes a charging barrel assembly (81) sealedly disposed at a joint between the molding device (10) and the smelting device (5) and an injection unit sealedly connected with the smelting device (5). The vacuumizing device (3) is sealedly connected with the smelting device (5) and the molding device (10) respectively so as to vacuumize the smelting chamber (501) and the molding chamber. The space volume which needs to be vacuumized is greatly reduced, thereby being favorable for guaranteeing the leakproofness and the pressure maintaining performance of a vacuum space.
