Abstract
Provided is a reflector comprising: an outer wall; and an inner wall which reflects the xenon lamp light from a xenon lamp toward an object to be light sintered, and which consists of inner side walls and an inner top wall which are spaced apart by a predetermined distance from the outer wall to allow cooling water for cooling heat generated by the xenon lamp light to flow, wherein at least a part of the inner side walls has the same thickness as at least a part of the inner top wall.
Claims12
A reflector comprising:
- an outer wall;
- an inner wall configured to reflect xenon lamp light from a xenon lamp toward an object to be light sintered and include inner side walls and an inner top wall which are spaced apart from the outer wall by a predetermined distance so as to allow cooling water for cooling heat generated by the xenon lamp light to flow;
- and
- a cooling tube in which cooling water flows while surrounding a xenon lamp,
- wherein a space between the outer wall and the inner wall provides a flow passage for first cooling water to cool the reflector and the cooling tube provides a flow passage for second cooling water to cool the xenon lamp,
- wherein a direction of the second cooling water flowing through the cooling tube and a direction of the first cooling water flowing in the space between the outer wall and the inner wall are different from each other.
A light sintering apparatus comprising:
- a xenon lamp;
- and
- a reflector having an outer wall and an inner wall configured to reflect xenon lamp light from the xenon lamp toward an object to be light sintered, and include inner side walls and an inner top wall which are spaced apart from the outer wall by a predetermined distance so as to allow cooling water for cooling heat generated by the xenon lamp light to flow;
- and
- a cooling tube in which cooling water flows while surrounding a xenon lamp,
- wherein a space between the outer wall and the inner wall provides a flow passage for first cooling water to cool the reflector and the cooling tube provides a flow passage for second cooling water to cool the xenon lamp,
- wherein a direction of the second cooling water flowing through the cooling tube and a direction of the first cooling water flowing in the space between the outer wall and the inner wall are different from each other.
