Abstract:
An interposer (30) for connecting two or more circuit boards (22, 26) is a circuit carrying substrate (32) with two or more solder pads (40, 44) on each of two sides (34, 36). Each of the solder pads (40, 44) are connected (42) to an electrically conductive via (38) in the substrate (32), providing electrical interconnection from one side (34) to the other side (36). One or more solder pads (40, 44) have a solder ball (46) on it. The interposer (30) has a contact area (48) suitable for the interposer (30) to be picked up and placed by an automated part placement machine (50). An electrical assembly (20) is made by soldering the solder balls (46) on one side (34) of the interposer (30) to corresponding solder pads (24) on a circuit board (22). The solder balls (46) on the other side (36) of the interposer (30) are likewise soldered to the corresponding solder pads (28) of a second circuit board (26).
Abstract:
An electronic module (10) is provided having enhanced thermal cooling of electronics. The module (10) includes a housing (12), electronic circuitry (14) contained within the housing (12), and a fluid cooling chamber (16) extending through the housing (12). The chamber (16) has generally conical shaped portions (18) at opposite ends. At least one thermal cooling insert (20) extends into the chamber (16). The insert (20) comprises a plurality of projections (24) for forming fluid flow passages (26) between adjacent projections (24), wherein the projections (24) engage the generally conical shape portion (18) of the chamber (16).
Abstract:
A method for increasing the convective heat transfer capabilities of a liquid cooler (11) coupled to various system and vehicle components. A structure (12) is placed within a hollow tubing (14) of the liquid cooler to distort the laminar flow of fluid within a center portion of the hollow tubing (14), which decreases the temperature rise of the fluid along an outer wall of the hollow tubing (14) associated with laminar flow. In preferred embodiments, the structure (12) consists of an elongated baffle wire or an extruded elongated ridge member. The structure (12) allows the outer surface of the tubing (14) to have increased cooling at a particular liquid flow rate, which allows more heat transfer capability to a coupled system or vehicle component as compared with liquid coolers without the structure.
Abstract:
A cooling apparatus 10 including an elongated body portion 12 having a fluid inlet 16, a fluid outlet 18 and a fluid channel 14 extending between the fluid inlet 16 and the fluid outlet 18, wherein the fluid channel 14 includes a generally "G," "C" or "( )" shaped cross-section.
Abstract:
A flat twisted electrical terminal (30) is provided for connecting a first circuit element (14) to a second circuit element (22) on respective first and second circuit boards (12 and 20). The terminal (30) includes a flat conductive member having a first end (32) for connecting to a first circuit element (14) and a second end (34) for connecting to a second circuit element (22). The conductive member is axially twisted about its longitudinal axis.
