12 Nov 1996TL;DR: In this article, a thermally conductive slug is mounted on the main circuit board of an integrated circuit to conduct heat generated by the die through a thermal interface to a heat sink or heat pipe.
Abstract: An integrated circuit package has a top die attach area and a bottom heat spreader thermally coupled to the die for conducting heat generated by the die through a thermal interface in the main circuit board to a heat sink or heat pipe mounted underneath the main circuit board. The preferred thermal interface is a thin, thermally conductive slug mounted through an opening formed in the main circuit board. The heat spreader spans the bottom surface of the integrated circuit package substantially parallel to the main circuit board and preferably extends substantially to the inner periphery of the pin arrangement which preferably, although not exclusively, is in a ball grid array. The opening formed in the main circuit board through which the thin, thermally conductive slug is fitted, is preferably substantially flush with the bottom surface of the main circuit board and juxtaposed against the heat spreader. A thermally conductive adhesive is preferably applied to the adjoining surfaces of the heat spreader and the slug.

TL;DR: In this paper, the authors present a review of tubular heat pipe systems for heat recovery and renewable applications utility and show that standard tubular pipe systems present the largest operating temperature range in comparison to other systems and therefore offer viable potential for optimization and integration into renewable energy systems.
Abstract: Advancements into the computational studies have increased the development of heat pipe arrangements, displaying multiphase flow regimes and highlighting the broad scope of the respective technology for utilization in passive and active applications. The purpose of this review is to evaluate current heat pipe systems for heat recovery and renewable applications utility. Basic features and limitations are outlined and theoretical comparisons are drawn with respect to the operating temperature profiles for the reviewed industrial systems. Working fluids are compared on the basis of the figure of merit for the range of temperatures. The review established that standard tubular heat pipe systems present the largest operating temperature range in comparison to other systems and therefore offer viable potential for optimization and integration into renewable energy systems.
