摘要:
In some embodiments, a semiconductor cooling apparatus includes a heat exchanger configured to thermally couple to a semiconductor element to transfer heat to coolant flowing through the heat exchanger. The apparatus also includes a flexible coolant supply manifold and a flexible coolant return manifold. The flexible coolant supply manifold and flexible coolant return manifold flex to conform to a height of the semiconductor element to apply a force to maintain the thermal coupling between the heat exchanger and the semiconductor element. The apparatus also includes a cold plate located under the semiconductor element, the cold plate configured to couple to the flexible coolant supply manifold via a first riser to provide coolant to the flexible coolant supply manifold and configured to couple to the flexible coolant return manifold via a second riser to exhaust returned coolant to the cold plate.

摘要:
A method of and tools for forming sewing machine binder strip folders for folding a cloth binder strip laterally as it is fed to the sewing machine needle for stitching the folded binder strip to fabric which is fed past the needle with the folded strip. The folder is formed from a flat bendable sheet by folding longitudinal edge portions of the sheet inwardly over the same side of the sheet to form the latter to an initial configuration having inwardly opening binder strip receiving channels along the longitudinal edges of the sheet, and then bending the longitudinal central portion of the sheet laterally and progressively from one end of the sheet while retaining the opposite end of the sheet in its initial configuration to (a) form a longitudinally extending and tapered center fold in the sheet, (b) form said one end of the sheet into a narrowed mouth, and (c) twist the channels of the sheet about longitudinal axis, whereby the mouth ends of th channels are angularlay displaced relative to their opposite coplanar ends.
