Cooling apparatus having vertical flow channels

A cooling apparatus characterized in comprising:

• a main body portion that has upper and lower openings;
• an upper portion heatsink and a lower portion heatsink that are mounted above and below said main body portion so as to cover said upper and lower openings of said main body portion;
• a partitioning plate that is disposed so as to divide an internal portion of said main body portion into upper and lower sections, so as to form an upper portion space with said upper portion heatsinks, and so as to form a lower portion space with said lower portion heatsink;
• a liquid coolant supplying header that is formed between one of said upper and lower portion heatsinks and said partitioning plate;
• a liquid coolant discharging header that is formed between the other of said upper and lower portion heatsinks and said partitioning plate so as to have a flow channel direction that is parallel to a flow channel direction of said liquid coolant supplying header;
• a vertical flow channel that is separated from said liquid coolant supplying header by a predetermined distance in a width direction that is perpendicular to said flow channel directions, that passes through said partitioning plate vertically, that extends at least parallel to said flow channel direction of said liquid coolant supplying header, and that communicates between said upper portion space and said lower portion space;
• and
• a liquid coolant distributing structural body that is disposed inside said liquid coolant supplying header, that is configured into a shape such that a flow channel cross-sectional area of said liquid coolant supplying header becomes gradually smaller from an upstream end toward a downstream end, and that distributes a liquid coolant that flows through said liquid coolant supplying header toward said vertical flow channel,
• wherein the liquid coolant supplying header and the liquid coolant discharging header are two separate channels through which the liquid coolant flows,
• wherein a width t of said vertical flow channel satisfies 0.75 mm≤t≤6.5 mm,
• wherein said upper portion heatsink and said lower portion heatsink comprise groups of radiating fins that are housed in said upper portion space and said lower portion space, and
• wherein a portion of a group of said radiating fins extend into at least one of said liquid coolant supplying header and said liquid coolant discharging header, and are formed such that fin height decreases gradually toward a central portion of said header.
