20100263843 | INCLINED WAVED BOARD AND HEAT EXCHANGER THEREOF - An inclined waved board and a heat exchanger thereof. The inclined waved board includes a board body composed of continuous waved sections. The waved sections are respectively inclined from a first side to a second side, inclined from the first side to a third side and inclined from a fourth side to the second side of the board body by an inclination. The waved sections define multiple raised sections and recessed sections on two faces of the board body. The heat exchanger is composed of multiple board bodies arranged adjacent to and in parallel to each other. Each two adjacent board bodies define therebetween a flow way. When fluids flow through the flow ways, the inclined waved sections enhance turbulence intensity and guide the fluids to produce secondary flows along the cross-sections of the flow ways so as to form dynamic three-dimensional swirling flow structure in the waved flow ways. The enhanced turbulence activities and the swirling flow structures augment heat transfer rates with less pressure-drop penalties from the likewise ribbed channel due to the smooth channel surface for the present invention. | 10-21-2010 |

20090096300 | LIGHT WEIGHT LOW COST MOTOR HOUSING AND COOLING FIN ASSEMBLY - A motor housing and cooling fin assembly for an electric motor comprises a stator support having a longitudinal base and a series of fin plates protruding radially from the base, the fin plates for directing fluid coolant through the motor, a cylindrical support sleeve comprising a thin wall, the thin wall containing a series of slots for receiving distal ends of the fin plates; and a motor housing having a cylindrical inner wall, the support sleeve positioned between the stator support and the motor housing in an interference fit. By reducing the thickness of the motor housing by more than the thickness of the added cylindrical support sleeve, the motor housing is lighter. Instead of machining slots directly into the motor housing, they are machined the cylindrical support sleeve, which is of simple geometry, thereby reducing the difficulty and cost of manufacturing. | 04-16-2009 |
