摘要:
The self chilling liquid container including a bottle having a top portion with an opening therein for filling the bottle and a removable cap, a closed bottom portion and an elongated center portion. An absorbent elastic exterior shell is received around an outer circumference of the center portion and secured thereto. The exterior shell may be permanently attached to the center portion or removably attached. When the exterior shell is saturated with water and is exposed to the atmosphere, the liquid within the shell evaporates at ambient temperature thus chilling the liquid inside the bottle by heat transfer. The chilling effect is substantially increased by airflow flowing past the flexible shell. In this manner, the primary source of heating of a liquid in the container, that is air flow, is changed to a primary source of cooling the liquid. The exterior shell is made of a hydrophilic open-cell elastomeric material that has sufficient thickness and void-volume to absorb several ounces of a cooling medium (i.e., water) and thus can provide an active evaporative cooling capability for the duration of the bicycle ride. In the event that all of the cooling medium evaporates from the shell, the enclosure material will still act as an insulator.

The compact rotary evaporative cooler of this invention includes a case containing a powered rotor mounting a partition that divides the case longitudinally into a wetted chamber and a nonwetted chamber. An annular array of elongated Perkins tubes is supported for rotation with the rotor and each Perkins tube extends through the partition, with the evaporation end section extending into the nonwetted chamber and the condensing end section extending into the wetted chamber. Each Perkins tube mounts a plurality of closely spaced heat conductive fins along its length, and a layer of porous metal is bonded to the entire inner surface of the evaporation section of the tube. A first inlet port introduces hot, dry outside air into the wetted chamber and a first outlet port vents the cooled but humidified air from the wetted chamber to the atmosphere or to a space to be conditioned. A second inlet port introduces atmospheric or compartment space air into the nonwetted chamber and a second outlet port vents cooled air from the nonwetted chamber for controlled mixing with the vented air from the first outlet port and delivery to a space to be conditioned. A water reservoir and pump supply water mist into the wetted chamber for wetting the finned heat transfer surfaces. A bootstrap mode may be provided by communicating outlet air duct 64 with inlet air duct 58 and outlet air duct 60 with the space 56. A controller valve 80 in inlet air duct 58 allows outside air to be mixed with air in duct 64.

An air-conditioner with high-efficiency differential cold-valley pipes, which include J pipes and a low-pressure circulating pump, has a first arc heat-exchanger which is formed by multiple-layer ladder-shaped corrugated plates and multiple-layer arc J pipe stacked alternatively, and a second arc heat-exchanger which is formed by multiple-layer arc J pipe and multiple-layer wave-shaped film-type evaporation face stacked alternatively. A low pressure pump is connected between the first arc heat-exchanger and the second arc heat-exchanger through pipelines. The air-conditioner solves the problems that the conventional air-conditioner consumes high energy, quality of the air in the room is low and the use of CFCs is confined.
摘要:
A modular semiconductor chip cooling system having a readily openable enclosure defining a chamber configured to hold a printed circuit board carrying components to be cooled. The enclosure can include a reservoir, a condenser and a pump. Sprayers within the chamber are adjustably mounted on one or more brackets to allow each sprayer to be set for the individual height of its respective component. The enclosure can be readily removed from a computer system through a quick release connection. The computer system can include a condenser and pump to operate all its modular cooling systems, removing the condensing function from the individual modules.

A must system for use in conjunction with a normally air cooled air conditioner condenser. The mist system provides cooling water to the coils and fins of the condenser to improve efficiency. Misting is normally off but comes on in response to pressure in the high pressure supply line from the condenser rising above a pre-set head pressure level.
摘要:
A closed circuit cooling tower for evaporative fluid cooler applications such as water-cooled residential and commercial air conditioning, geothermal cooling supplementation, and process cooling applications. Corrugated metal tubes are used for heat transfer to permit mechanical de-fouling, such as flexing the tubes. The cooling tower may operate at high dissolved solids, or gray water may be used in order to reduce water consumption. The cooling tower is lightweight and modular to permit retrofitting of existing rooftop air conditioning systems so that efficient evaporative cooling may be used to lower energy costs.

In one embodiment, the present invention provides a high performance molded, substantially non-metallic fan capable of producing at least about 20 cubic feet per minute (“CFM”) per input watt at a static pressure of about 0.00 inches of water. In one embodiment, the fan combines a substantially non-metallic housing, an airfoil cross-sectional fan blade, and a non-metallic hub. The fan blades may be detachable from the hub and rotationally indexable to a variety of pitch angles. Further, the hub and fan blades may include alignment indicia, so that the fan blades can be adjusted to a commensurate pitch relative of other fan blades around the hub.

A self tapping spray nozzle for use in a vehicle ventilation system is preferably made of stainless steel. The spray nozzle has a neck with an internal channel and threads cut into its outside surface. A wedge at a thirty degree angle, having sharpened edges is at the top of the neck. At least one port extends from the channel to the outside surface of the neck. A collar with a plurality of sides encompasses the circumference of the neck at its bottom. One side of the collar is aligned with the port to help align the port in a desired direction.
摘要:
An evaporative cooler in which a series of evaporative pads are positioned in a spaced apart relationship. Water from a reservoir is deposited onto the pads to moisten them. As the water on the pads evaporates, the surrounding air is cooled; thereby becoming denser and settling through the outlet at the bottom of the housing and into the area to be cooled. The falling cool air draws in warm air at the top of the housing, which in turn is then cooled by the pads to continue the cycle.

Novel heat exchangers and methods of constructing the heat exchangers for use in indirect evaporative cooling applications. The evaporative apparatus for cooling comprises both a multi-stage indirect evaporative cooling heat exchanger; and a multi-stage sump where each sump stage, in a one-to-one relationship. Other multistage heat exchangers with their associated multistage sumps can be combined, with the cooled air of a first multistage evaporative assembly feeding into the intake end of a second multistage evaporative assembly, and so on. These heat exchangers can be used for comfort and industrial applications cooling. The invention can be an entire assembly for the pre-cooling and cleaning of the air going to a gas turbine or any other air breathing device, with an air washer stage in which air is directly cooled by evaporation and where simultaneously the air is also cleaned of dust, dirt and other impurities.
