20110259550 | WIND-PRESSURE SHUTTER AND COOLING FAN SYSTEM - Plural flaps provided in a wind-pressure shutter are located approximately parallel to a direction of an airflow path, i.e., the airflow path is opened. Thus, the wind-pressure loss of cooling wind passing through the shutter can be reduced to near zero during the normal operation of the fan. If an air-backflow flows from the exhaust vent due to a fan failure, the flap slightly inclined toward the airflow path receives wind pressure of the air-backflow on its surface, thereby swings about the support shaft to close the airflow path. | 2011-10-27 |

20110259556 | DEVICE FOR GENERATING COMBUSTIBLE PRODUCT GAS FROM CARBONACEOUS FEEDSTOCKS - A device is provided for generating combustible product gas from carbonaceous feedstocks through allothermal steam gasification in a pressurized gasification vessel. The pressurized allothermal steam gasification of carbonaceous fuels requires that heat be supplied to the gasification chamber at a temperature level of approximately 800-900° C. In a heat pipe reformer, as is known from EP 1 187 892 B1, combustible gas is generated from the carbonaceous feedstocks to be gasified through allothermal steam gasification in a pressurized fluidized bed gasification chamber. The heat needed for this is fed to the gasifier or reformer from a fluidized bed combustion system through a heat pipe arrangement. Due to the straight and tubular construction of heat pipes, the combustion chamber and reformer/gasification chamber are disposed one above the other in the known heat pipe reformer from EP 1 187 892 B1. The pressure vessel base is under particular stresses due to the high temperatures in the combustion chamber. In addition, the base is weakened by a plurality of heat pipe feedthroughs. The sealing of the feedthroughs also presents a problem. In conventional tubular heat pipes, the line for liquid heat transfer medium and for gaseous heat transfer medium are both disposed in the common tubular shell. The fact that the present invention uses loop heat pipes in which the liquid heat transfer medium is conveyed spatially separated from the gaseous heat transfer medium allows the number of feedthroughs to be reduced to two, namely a liquid line and a vapor line. When a plurality of such loop heat pipes is used, the separate vapor and fluid lines thereof can be combined in the | 2011-10-27 |
20110259557 | HEAT DISSIPATION APPARATUS INCORPORATING AIRFLOW GENERATOR - A heat dissipation apparatus includes a heat sink defining a plurality of air passages therein, and an airflow generator arranged on the heat sink and including a plurality of airflow-generating units.

The driving member is capable of vibrating the vibration diaphragm when alternating voltage is applied thereto. When the driving member vibrates the vibration diaphragm towards the bottom wall of the casing, the vibration diaphragm compresses the air inside the second chamber of the casing towards the orifice, generating airflow from the orifice to the air passages of the heat sink. | 2011-10-27 |
