    • A body having a bottom and first and second ends and a cavity therein. A plurality of substantially parallel spaced fins are positioned in the cavity. A liquid inlet is centrally positioned in the first end of the body and a liquid outlet is centrally positioned in the second end of the body where flowing cooling liquid between the fins from the first end to the second end with higher fluid flow between the fins in the center for preferentially cooling the center of the heat exchanger. A cross-sectional area of the liquid path in the body minimizes pressure drops and avoids abrupt direction changes and cross-sectional changes. The width, height and spacing of the fins may be varied to control the temperature of the areas in the bottom.
    • 具有底部和第一和第二端以及其中的空腔的主体。 多个基本上平行的隔开的翅片定位在空腔中。 液体入口位于主体的第一端中央并且液体出口居中地位于主体的第二端中,其中,在翅片之间的冷却液体从第一端到第二端之间流动,翅片之间的流体流动更高 用于优先冷却热交换器中心的中心。 体内的液体通道的横截面积使压降最小化并避免突然的方向变化和横截面变化。 翅片的宽度,高度和间距可以改变以控制底部区域的温度。

    • A pin fin heat exchanger is made by wrapping a thermally conductive wire having a coating thereon around a mandrel thereby forming a multilayer coil. The coating is fused together for holding the wires together. The method includes cutting a section out of the coil providing a plurality of generally parallel wires having first and second ends and placing the cut section between an object and a wall for transferring heat therebetween with the first ends engaging the object and the second ends engaging the wall. Thereafter the coating is removed from the wires such as by solvents. The ends of the wires may be soldered or may be lapped to provide a convex surface to provide good heat transfer.
    • 销翅式热交换器通过将其上具有涂层的导热丝缠绕在心轴上而形成多层线圈而制成。 将涂层熔合在一起以将电线夹在一起。 该方法包括从线圈中切出一段,提供多个具有第一和第二端的大致平行的线,并将切割部分放置在物体和壁之间,用于在其间传递热量,其中第一端接合物体,而第二端接合物体 壁。 此后,例如通过溶剂从涂层中除去涂层。 电线的端部可以被焊接或可以被重叠以提供凸形表面以提供良好的热传递。

    • A lubricant free low cost overload release clutch having a spring housing with an integral hub, a detector ring containing fixed detent bullets for engagement with springs in the housing on one side, and a bullet detent housing on the other side, together with spider cushion and shaft housing engaged for rotary turning with the bullet detent housing in response to the rotation of a shaft in the shaft housing. The release clutch responds to preset torque limits determined by spring tension. After a disengagement caused by excess torque, the clutch will reset by further rotation of the detent housing.
    • 一种无润滑剂的低成本过载释放离合器,具有一体式毂的弹簧壳体,一个包含固定止动子弹的检测器环,该固定止动子弹与一侧的壳体中的弹簧接合,另一侧具有一个子弹制动器壳体,以及蜘蛛垫和 所述轴壳体响应于所述轴壳体中的轴的旋转而与所述子弹棘爪壳体接合用于旋转车削。 释放离合器响应由弹簧张力确定的预设扭矩限制。 在由过大扭矩引起的脱离接合之后,离合器将通过制动壳体的进一步旋转而复位。
