Abstract: A heat-dissipating assembly includes a body and a bottom plate. The body has a heat-absorbing portion. The interior of the heat-absorbing portion is provided with a chamber covered by the bottom plate. The chamber has an evaporating region for generating a high pressure, and a condensing region for generating a low pressure. The pressure gradient between the evaporating region and the condensing region is used to drive the circulation of liquid/vapor phase of a working fluid. With this structure, heat can be conducted rapidly without providing any wick structure.

Abstract: A cooler device for a motor vehicle includes a radiator liquid cooler with a first cooler element for cooling radiator liquid for the motor vehicle's combustion engine, a charge air cooler with a second cooler element for cooling of charge air for the combustion engine, the first and the second cooler elements extending substantially parallel and side by side, with a narrow space between the cooler elements. A screening device in the space between the cooler elements regulates the air flow through the elements. A control mechanism switches the screening device to and fro between an open position in which the screening device does not, or at least does not appreciably, limit the air flow through the cooler elements, and a closed position in which the screening device limits the air flow through the cooler elements.

Abstract: A geothermal sleeve for a building structure keeps air at a moderate temperature by passing through a geothermal heat exchanger (e.g., pipes) located underground. The moderate air is drawn up from the underground pipes and pumped into existing spaces between the interior and exterior walls (or surfaces) of a dwelling. The moderate air fills in the spaces between the interior and exterior walls to create a geothermal sleeve to supplement climate control inside the building structure.

Abstract: This invention provides a heat transfer device which can improve its heat transfer performance in a heat exchanger with a flow rate of heat carrier fluid being set at a relatively low velocity, while restricting increase in pressure loss of the fluid flow. Plural longitudinal vortex generator winglets (10) are arranged in a spanwise direction on each side of the heat transfer object (T). The winglets on each side are oriented substantially in the same direction for deflecting the fluid to the same direction and conducting the fluid to an area behind the object. Each of the winglets has a configuration gradually decreasing in its height toward an upstream side of a flow of the fluid. Longitudinal vortices are produced behind the winglets by the fluid flowing rearward beyond the winglets.
