A laundry dryer is provided with a modular air recirculation subassembly fitted beneath a rotatable drum of the dryer. The subassembly has an air recirculation passage provided between an air supply passage and an air exhaust passage of the dryer. The air recirculation subassembly further has a flow directing flap at the juncture of the air inlet passage and the air recirculation passage to direct the recirculation air flow toward a heater and away from an inlet end of the air supply passage. The air recirculation subassembly may include a filter positioned across the air recirculation passage upstream of the heater, which filter is removable through the air exhaust passage. The subassembly may further include a heat exchanger to transfer heat from the warmer air exiting the exhaust passage to the cooler air entering the air supply passage, and a recirculation air flow regulating flap.

A heat dissipation device is to be mounted in a computer enclosure for dissipating heat generated by a VGA card (10). The heat dissipation device includes a heat sink (90), a fan (60) and a fan duct (50) connecting the heat sink (90) and the fan (60). The heat sink (90) contacts a heat-generating device (12) of the VGA card. The fan (60) has an inlet port (62) and an outlet port (63). The outlet port (63) communicates with an ambient air outside the computer enclosure. The fan duct (50) has two open ends (55,52). One open end (55) engages with the heat sink (90) and the other open end (52) engages with the inlet port (62) of the fan (60).

An external heat dissipation device includes a housing, a circuit board placed in the housing, a fan electrically connected to the circuit board, and a wire electrically connected to the circuit board to power the fan. The housing includes an installation dock defining a receiving space for receiving the fan therein, and an insertion portion extending from the installation dock. A through hole is defined in the installation dock. An air passage is defined in the insertion portion. The fan includes a casing defining a first air hole communicating with the through hole and a second air hole communicating with the air passage.

An efficient system to heat the insole of a heated insole of a shoe in which the Intelligent Circuit (IC) for a flat lithium battery is located outside the shoe and the placement of the heater for the insole is between more efficient heat insulation and heat conducting members.

A heating element includes a support made of flexible material and a flexible grid structure with an electrically conductive paste disposed on the support.

A microwave water heating system includes a metal casing having an outer wall defining an interior casing chamber. An inner housing is positioned within the casing and includes an outer wall displaced from the casing outer wall to form an insulating vacuum space. The inner housing includes an inlet port connected to an upstream water source and an outlet port connected to a downstream conduit. The casing and inner housing include generally spherical configurations. The inner housing is configured to induce a vortex of a water stream flowing between inlet and outlet ports. At least one magnetron is mounted to the casing for transmitting microwaves into the inner housing for heating the water stream at the vortex. A float valve in the inner housing allows the water stream to flow and be heated upon demand as the valve operates according to upstream and downstream pressure differentials.

A system for crystal growth having rapid heating and cooling. A fluid-cooling jacket having a reflective shield contained therein is disposed around a heating cylinder in which crystal growth takes place. A heating coil is disposed round the cooling jacket. The invention also includes a method of crystal growth and semiconductor devices formed using the inventive methods and systems.

The present invention provides a modular fluid warmer and a method of stacking a plurality of modular fluid warmers. As each of the modular fluid warmers is independently operated, the modular fluid warmers are energy efficient. Further, each modular fluid warmer may be equipped with sensors and a controller that reduces the required amount of user interaction with the modular fluid warmer.

Non-evaporable getter pump assembly (1) for a vacuum solar thermal panel, ensuring a quick and efficient heating of the getter pump, comprising: a solar receiver plate (2), having an outer side (20) predisposed for absorbing solar radiation; at least a first supporting plate (3a); at least a non-evaporable getter element (4) interposed between an inner side (21) of the solar receiver plate (2) and the first supporting plate (3a); and holding means for pressing the solar receiver plate (2) and the first supporting plate (3a) against one another sandwiching the non-evaporable getter element (4) between the two plates (2, 3a).

An apparatus for heating a fuel cell assembly is disclosed, wherein a means for heating is disposed in a manifold of the fuel cell assembly and the means for heating causes the manifold to be heated to militate against fluid condensation and ice formation in the fuel cell assembly.

A washcloth steamer is designed as a counter top device for a consumer to effectively and efficiently heat a single, wetted washcloth to a temperature of between 150 and 212 degrees Fahrenheit. The washcloth steamer is formed with a bowl-type housing containing a heating plate therein. The wetted washcloth is provided around or about upper and lower surfaces of the heating plate. When the clamshell type housing is closed about the heating plate and wetted washcloth, the heating plate is activated to heat the wetted washcloth for a predetermined or until the washcloth or the heating plate reach a maximum temperature. Because the heating plate is configured to quickly heat the washcloth and water, a moisture sensor is included that is relied upon to deactivate the heating plate if the detected moisture is too low, to avoid singeing or igniting the washcloth.
