摘要:
A heat sink (2) has a base (4) having a first surface (4a) thermally connected to a heat producing body and also has fins (6a-6d) each having through-holes (8), the fins being supported by a second surface (4b) of the base (4) and arranged in a predetermined direction. The base (4) and the fins (6a-6d) are integrally formed of a porous material (lotus-type porous material). The heat sink (2) is placed in a duct (80). It is preferable that the width (W) of the heat sink (2) is substantially equal to or less than 10 mm.
摘要:
A heat sink includes a base having a first surface thermally connected to a heat producing component and a plurality of fins supported by a second surface of the base and arranged in a predetermined direction, each fin having a plurality of through-holes. The base and the plurality of fins are integrally formed from a porous material, for example a lotus-shaped porous material. The heat sink is placed within a duct. The heat sink may have a width of about 10 mm or less.

A heat transport device includes a container having a hollow structure including a fluid channel, at least one thermal-receiver heat exchanger and one thermal-radiator heat exchanger arranged side-by-side on an outer wall of the container along the fluid channel, and driving heat exchangers at respective terminal portions of the container. In this heat transport device, both ends of the fluid channel are closed to prevent intrusion of external air, and a liquid and a gas are sealed in the fluid channel. The driving heat exchangers cause the liquid to oscillate in the container along the internal fluid channel. The heat transport device provides low acoustic noise performance, improved temperature controllability, high heat transportation and heat radiating capacities, and improved heat transfer and fluid flow characteristics.

A low-cost heat sink easy to assemble which is designed to be mounted on a power semiconductor module (5) through the medium of cooling water includes a base member (1), a heat sink body (2) superposed on the base member (1) to form in cooperation with the base member (1) a passage through which the coolant flows, and a bellows-like flow straightening plate (6) disposed between the power semiconductor module (5) and the base member (1) in physical contact with the power semiconductor module (5) on one hand and with the base member (1) on the other hand. The flow straightening plate (6) partitions the passage into a plurality of flow straightening channels (14A, 14B).
