A portable heater adapted for use in a recreational enclosure or temporary work enclosure includes a housing having an air inlet on the lower front face. A gas supply is partially enclosed by the housing which provides propane to the mouth of a burner venturi located within the housing. Air is drawn through the air inlet and also enters the mouth of the burner venturi. The air and gas are mixed thoroughly as they travel upwardly through the burner venturi. A chimney effect increases fresh air flow velocity into the burner venturi and allows the heater to operate at a reduced fuel gas pressure. Upon exiting the burner venturi, the air/gas mixture is to a plenum and radiant surface where combustion takes place. Any conventional means may be provided to ignite the air/gas mixture in order to cause combustion. The combustion products deflect off a deflector, which is cooled on a rear face by air flow through the housing, which decreases the temperature of the combustion products before exiting an outlet. An oxygen depletion system (ODS) shuts off the portable heater when oxygen levels begin to drop and consequently carbon monoxide levels begin to rise.

An electro-kinetic air conditioner for removing particulates from the air creates an airflow using no moving parts. The conditioner includes an ion generator that has an electrode assembly including a first array of emitter electrodes, a second array of collector electrodes, and a high voltage generator. Preferably, a third or leading or focus electrode is located upstream of the first array of emitter electrodes, and/or a trailing electrode is located downstream of the second array of collector electrodes. The device can also include an interstitial electrode located between collector electrodes, an enhanced collector electrode with an integrally formed trailing end, and an enhanced emitter electrode with an enhanced length in order to increase emissitivity.

A wind turbine including a stator assembly having a plurality of stator blades for tangentially redirecting wind into a rotor assembly having a plurality of vertical rotor blades disposed circumferentially on a plurality of disks stacked one on top of each other. Each disk defines at least one opening thereon for redirecting the wind axially through each of the disks.

The invention belongs to the technical field of kitchen appliances, and particularly relates to an integrated cooker. The integrated cooker comprises a machine body and a range hood body; the range hood body comprises an air inlet, an air collecting box and a fan assembly; the air collecting box communicates with the air inlet; the fan assembly is arranged in the air collecting box; a volute air duct of the fan assembly extends downwards to the wall face of the bottom of the air collecting box and extends out of the bottom of the air collecting box to be rotationally provided with an air outlet base; and an air outlet is formed in one side of the air outlet base. According to the integrated cooker, the volute air duct extends downwards to the wall face of the bottom of the air collecting box and extends out of the bottom of the air collecting box to be rotationally provided with the air outlet base; the air outlet base is directly located on the outer side of the air collecting box, and the situation that a channel is located inside and occupies too much space is avoided; a through hole does not need to be additionally formed in the side edge of the machine body, and leakproofnessof the side face of the machine body is guaranteed; and meanwhile, the air outlet base is rotatably arranged, so that a user can conveniently adjust the air outlet direction according to actual needs,and humanization is achieved.

Embodiments for a charge air cooler are provided. In one example, an engine method comprises during a first mode, decreasing a volume of a charge air cooler in response to a compressor operation upstream of the charge air cooler. In this way, compressor surge may be prevented.

A LED street lamp including a housing, a lighting module, a metal base, and a heat dissipating module. The housing includes a bottom shell and a top shell both with openings. The lighting module is arranged in the housing. The heat dissipating module includes a metal base, a plurality of heat pipes, and a plurality of heat dissipating fins. The metal base includes a first plate and a second plate attached together. The first plate is thermally contacted with the lighting module. The heat pipes each have a heat absorbing section and a heat dissipating section. The heat absorbing section is arranged between the first plate and the second plate. The heat dissipating section is extending away from a side of the metal base. The heat dissipating fins are arranged on the heat dissipating sections. Air in the housing can naturally flow upwardly to effectively dissipate operating heat.

An improved fuel air mixture apparatus which enhances the degree of mixing of fuel with air. The fuel-air mixture device includes a primary air passage having an inlet, an adjustable throttle and an outlet; a secondary air passage having an inlet and an outlet to the primary air passage between its adjustable throttle and its outlet; a nozzle having an orifice opening into the secondary air passage for introducing a flow of fuel therein; a needle arranged co-axially of the nozzle with its small diameter at least normally extending from the orifice into the secondary air passage, the needle being axially moveable to provide variability of the orifice and control of the fuel flow; a control device for directly linking or controlling the position of the needle to the position of the adjustable throttle in the primary air passage for adjustment of the orifice of the nozzle. The arrangement is such that the fuel flow from the nozzle is matched to the position of the adjustable throttle and the fuel flowing from the orifice towards the small diameter end of the needle mixes with air flowing through the secondary passage prior to mixing with the air flowing through the primary air passage.

The invention relates to a low flow resistance supersonic device for purifying and separating gas and is applied to the field of gas separation and purification such as natural gas dehydration, etc. Natural gas enters a laval nozzle by a gas inlet, the temperature and pressure thereof lowers, the speed is increased, then the gas mixture floating at high speed flows through a whirl vane, the swirl with high speed is produced, the swirl with high speed enters a separation pipe, for the temperature becomes low, when the gas is below ground pressure and saturation temperature, the water or partial dew points in the gas are condensed into liquid, for the centrifugal forces born are different, the liquid from the gas by condensation is 'flung' to the wall of the pipe and forms a very thin layer of liquor film, the liquid flows out of the separation pipe through the ring-shaped groove between the separation pipe and a diffuser pipe and flows out from the liquor outlet. Then the dry gas in which water is removed enters the diffuser pipe, and the gas flows out of the separation device by the gas outlet. The device does not comprise motion components and structure is simple; and the circulation transversal area of the laval nozzle in the device is ring-shaped and can be processed easily.
