COOLING MEMBER, AND METHOD AND DEVICE FOR MANUFACTURING SAME

摘要

A cooling member (19) includes a heat-transfer member (9) having a groove (11) and a refrigerant introducing pipe (17) pressed into the groove (11). The refrigerant introducing pipe (17) has a pressed region (23) positioned inwardly of the edge (15) of the heat-transfer member (9), and at least one curbed surface portion (25). A method for manufacturing a cooling member (19) includes the steps of: preparing a punch (7) having at least one curbed corner (3) and a pressing surface (5), positioning the corner (3), and moving the punch (7) closer to the groove (11) to press the refrigerant introducing pipe (17) into the groove (11) with the pressing surface (5). A device (1) for manufacturing a cooling member (19) includes the punch (7) and a support (13) configured to support the heat-transfer member (9) so the groove (11) is positioned opposite to the punch (7).
