Abstract: An electronic board 200 has a heat generating component 220 mounted on it. An enclosure 300 houses the electronic board 200. A heat transport unit 400 is coupled to the enclosure 300 and transports heat generated by the heat generating component 220 to the outside. A heat receiving unit 510 is provided in a heat transport unit 400, 400A. The heat receiving unit 510 receives heat generated by the heat generating component 220. A heat dissipating unit 530 is provided in the heat transport unit 400 in such a manner that a portion of the heat dissipating unit 530 is exposed to outside air, and is coupled to the heat receiving unit 510. The heat dissipating unit 530 dissipates heat received by the heat receiving unit 510 to the outside. A guide duct unit 340 is formed into a tube interconnecting the heat generating component 220 and the heat receiving unit 510 in order to release heat of the heat generating component 220 to the heat receiving unit 510. This enables the heat generating component on the electronic board to be efficiently cooled with a small and simple configuration.

Abstract: A rack louver 120 controls an air flow of outside air external to an enclosure 10 taken into the enclosure 10, flowing from an inlet 20 to an outlet 30 in a rack 60. An outlet louver 130 controls an air flow of inside air internal to the enclosure 10 flowing out from the outlet 30 to outside the enclosure 10. A system control unit 150 adjusts motive power of a blowing unit 40, a degree of opening of the rack louver 120, and a degree of opening of the outlet louver 130 in accordance with an outside-air temperature measured by an outside-air temperature sensor 50 and electronic equipment power consumption measured by a power sensor 100. Consequently, electronic equipment in the rack can be cooled with higher energy efficiency while suppressing temperature rise in the electronic equipment.
