Cooling system for an electronic system

摘要

The invention relates to a cooling jacket (100) for use in electronic apparatus having a heat-generating element (200) therein, for transmitting heat generated from the heat-generating element (200) into a liquid coolant flowing therein. The cooling jacket (100) comprises a cover (130) building up a heat transfer surface to be in contact with a surface of the heat-generating element (200), a passage (110) for the liquid coolant, which is formed neighboring the heat transfer surface and wound round in an "S"-like manner inside the main body (120) of the cooling jacket (100), and an inlet (111) and an outlet (112) attached at both ends of the flow passage for the liquid coolant, and further a dispersion member (150) is disposed in the flow passage, being built up by gathering a plural number of members (150), each of which has a "U"-like cross-section and an aspect ratio of 10 to 20, thereby diffusing the liquid coolant therein, so as to transfer the heat from the heat-generating element (200) thereto with high efficiency, and thereby enabling to cool down the heat-generating element (200), fully, even with a relatively small amount or volume of the liquid coolant.
