Title:
HEAT-RADIATING DEVICE CASING HAVING REFRIGERANT PIPE EMBEDDED THEREIN AND APPARATUS AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/050122
Kind Code:
A1
Abstract:
The present invention relates to a heat-radiating device casing having a refrigerant pipe embedded therein and a method and an apparatus for manufacturing the same, the heating-radiating device casing comprising: a casting mold having a cavity formed therein so as to correspond to a casing body such that the casing body is molded by a molten metal supplied therein through a runner, and a refrigerant pipe being installed inside the casting mold such that both ends thereof are exposed to the outside, thereby guaranteeing that the refrigerant pipe is embedded in the casing body after gravity casting; a cooling supply portion for cooling and supplying air; a heating supply portion for heating and supplying air; a supply line to which cooled air and heated air are selectively supplied from the cooling supply portion and the heating supply portion, respectively, first and second branching ends being connected to ends thereof, respectively, so as to branch off toward both sides thereof and to be connected to both ends of the refrigerant pipe in an attachable/detachable manner, respectively, and first and second control valves being installed on the first and second branching ends, respectively; a first discharge line branching off from the rear end of the first control valve on the first branching end, a third control valve being installed in the first discharge line; a second discharge line branching off from the rear end of the second control valve on the second branching end, a fourth control valve being installed in the second discharge line; an air transfer portion for supplying air to the refrigerant pipe; and a control portion for controlling the first to fourth control valves so as to switch, at each first setting time, between operations of air supply through the first branching end and air discharge through the second discharge line and operations of air supply through the second branching end and air discharge through the first discharge line, thereby alternately changing the air supply side and the air discharge side with regard to the refrigerant pipe.
