Abstract: The terminal unit includes a main board, electronic components implemented on the main board, a sub-board covering above the electronic components and a frame member so disposed between the main board and the sub-board as to surround the electronic components. A flexible printed circuit covers an outer side of a wall portion of the frame member and is so wound around the frame member from upper and lower sides of the wall portion as to cover at least part of an inner side of the wall portion. A wiring pattern formed on the flexible printed circuit is electrically connected to the electronic components, and information to be protected that is stored on the electronic components becomes unreadable if the wiring pattern is cut off or short-circuited.

Abstract: A cooling device for cooling a heat-generating component includes a circulating passage arranged to have coolant circulate therein, a centrifugal pump including a first case made of metallic material, a second case made of resin material, and an impeller accommodated in the pump chamber, and a radiator provided at the circulating passage and being operable to release heat from the coolant. The first case has a surface arranged to contact the heat-generating component. The second case forms a pump chamber between the first case and the second case. The pump chamber stores the coolant therein. The impeller includes open-type vanes arranged to pressurize the coolant as to have the coolant flow through the circulating passage. The cooling device has a high cooling efficiency as well as a high operating efficiency of the motor while having a simple construction and a small overall size and a small thickness.

Abstract: A radiator includes: an inlet header having a hollow shape and being provided with an inlet for the coolant to enter; a plurality of flat tubes connecting to the inlet header on one end; and an outlet header having a hollow shape and being provided with an outlet for the coolant to discharge, the outlet header connecting to another end of the plurality of flat tubes. The plurality of flat tubes form channels for the coolant and connect the inlet header and the outlet header.

Abstract: The invention provides a cooling device including a heat-receiver integrated pump that has a heat-receiving part provided on one side thereof and delivers toward a connecting pipe liquid refrigerant on which a heat exchange has been performed through the heat-receiving part. A first radiator having a plurality of radiation fins radiates heat by exchanging heat with the liquid refrigerant sent via the connecting pipe. A second radiator having a plurality of radiation fins radiates heat by exchanging heat with the liquid refrigerant similarly to the first radiator. A fan blows air toward the first radiator and the second radiator. A base, constituting a fan casing, regulates an air-blowing direction of the fan, and includes a fan cover and a reserve tank. Liquid refrigerant within the reserve tank is thermally connected to a member forming an air-blowing path of the fan.

Abstract: A circulation path, a radiator and a reserve tank which can remove air bubbles from the fluid passageway, constitute parts of a closed circulation path, and are formed by joining a flow path wall-forming radiation board on which curved surfaces as flow path walls are formed, with a flat plate-like flow path wall-forming radiation board as another curved surface by welding or the like. Therefore, the efficiency of heat exchange of a cooling apparatus for electronic equipment can be improved, removal of air bubbles from the flow passageway and reduction in size, weight and thickness is made possible without causing air lock.
