A server system with a cooling ability that can cope with an increase in the amount of heat generated by a CPU of a server module detachably mounted on a blade server. The server module includes an enclosure accommodating therein a motherboard on which a CPU, memory, and the like are mounted, and part of a boil cooling device for cooling heat generated by the CPU. A fan accommodated in a fan module is adapted to blow air into the server module through an opening of the server module enclosure. The boil cooling device includes a first heat transmission member disposed in the server module enclosure, a second heat transmission member disposed outside the server module enclosure, and a plurality of pipes connecting them. The first heat transmission member is a box body with an internal space for hermetically sealing a refrigerant therein, one external planar face of which is thermally connected to the CPU and the other external planar face of which is provided with a heat sink. The second heat transmission member is disposed in the fan module unit, and a heat radiation member provided for the pipes forms an airflow passage together with the motherboard.

The disclosed heating device is to perform a heating process on an exposed substrate formed with a resist film before a developing process, the device including a heating part to perform a heating process on the exposed substrate, the heating part including a plurality of two-dimensionally arranged heating elements; a seating part provided at an upper side of the heating part, on which the substrate is disposed; and a control part to correct a setting temperature of the heating part based on temperature correction values, and to control the heating part based on the corrected setting temperature, during the heating process on one substrate by the heating part, wherein the temperature correction values being previously obtained from measured critical dimensions of the resist pattern in another substrate formed with the resist pattern through the heating process by the heating part and then the developing process.
摘要:
In the electronic device such as computer and server which is operated in full day time and having high load condition in a limited time schedule, a suitable cooling device is provided for the heat generating elements which consists of the electronic device. The cooling device also has an feature to avoid the enlargement of the cooling device and have high power efficiency. The heat generated in the heat generating element is both transferred to a heat sink and a heat accumulator. The heat accumulator is also connected to the heat sink. The heat generating element and the heat accumulator is thermally connected by a heat pipe. And the heat accumulator and the heat sink is also thermally connected by another heat pipe.
摘要:
From a plurality of preset operation modes, an optimal mode is selected to let the supply air 206 attain a predetermined temperature and humidity. Upon adjusting the opening degrees of dampers 116-119, a cold water valve 156 and a humidifying water valve 154, the system measures the outside air 201, supply air 206 and return air 207 for temperature and humidity to see if a mode boundary is exceeded. If the boundary is exceeded, an assessment time is set. The humidity of the supply air 206 in the mode in effect before the boundary is exceeded is further predicted so as to determine whether the predicted value exceeds the upper limit of a tolerable humidity range or drops below the lower limit thereof.
