Abstract: A prismatic secondary battery includes a battery case in a prismatic shape and a battery cover which seals up an opening part of the battery case. The battery cover has a convex part which projects toward the inside of the battery case, faces an inner surface of a side wall part of the battery case, and extends continuously along the entire periphery of the side wall part. Cover thickness of a contact part of the battery cover which is in contact with the upper end of the side wall part of the battery case at a position outside the convex part is greater than ½ of cover thickness of a blockage part blocking up an opening part at a position inside the convex part and is less than the cover thickness of the blockage part.

Abstract: A heat receiving jacket in a liquid cooling device for electronic equipment, for transferring a heat from a heating portion in the electronic equipment to liquid refrigerant, is composed of a fin piece having a base portion formed thereon with thin fins which rise up from one surface of the base portion, being curved, and a casing accommodating therein the fin piece in its center part so as to cause the liquid refrigerant to flow between the thin fins. Further, the cooling device includes a plurality of heat receiving jackets and a plurality of heat radiating portions which are alternately connected so as to constitute a passage for the liquid refrigerant, a part of the passage being connected with a circulation pump so as to constitute a closed circulation passage for the liquid refrigerant. With this configuration, it is possible to provide a liquid cooling device capable of decreasing the temperature rise of a heating element such as a CPU, having a high performance and being excellent in costs.

Abstract: In an information processing apparatus with a cooling structure using a heat transport measure such as a heat pipe and a liquid-cooling system, a heat radiation unit has reduced thickness and noise and an improved efficiency. Heat generated by a CPU is transmitted through a heat receiving header and a flexible tube to the heat radiation unit by liquid coolant transported by a pump. The heat radiation unit comprises a propeller, a wall surface in contact with the propeller, and a cooling pipe spirally wound around a propeller shaft in a plane perpendicular to the propeller shaft. Hot coolant is circulated so as to enter the central portion of the cooling pipe and to be discharged from the outer peripheral portion of the pipe. The cooling air from the propeller is made to flow from the central portion of the cooling pipe toward its peripheral portion. The cooling pipe is thermally connected to the wall surface so that the wall surface works as a heat spreader.
