    Abstract: A new method of sandwiching evaporative cooling materials such as Polyacrylamide crystals in between two or more outer layers of thin membrane is disclosed. The Polyacrylamide crystals are retained through the heat welding—as opposed to the traditional stitching—of the outer membranes to each other. This allows for the resulting material to be cut into a variety of patterns that can later be sewn or heat welded together to form a variety of cooling products. It also allows for heat-stamping where the heat-stamping machine has patterns that are welded onto the membranes, trapping the evaporative cooling components in one or more patterns, which can be located over specific body regions for effective cooling and/or cushioning and protection of that body region. Patterns can be designed such that negative spaces are created, whereby airflow can be channeled to accelerate the evaporative cooling process over certain body regions.

  • Patent number: 7752860
    Abstract: A method and apparatus for improving the rate of heat transfer between an evaporator of a refrigeration system and the environment surrounding the evaporator. In one embodiment, the evaporator is placed in thermal communication with the air of a data center where electronic equipment is operated therein. To improve the rate of heat transfer between the air and the evaporator, water is evaporated into the air before it flows over the evaporator coils. As a result, when the humidified air flows over the cold evaporator coils, a portion of the water vapor in the air condenses on the evaporator, thereby wetting the evaporator coils. The wetted surfaces of the evaporator coils improve the rate of heat transfer between the air and, ultimately, the refrigerant passing through the evaporator. In one embodiment, a humidifier having a water atomizer may be used for spraying and dispersing water into the air.

    Abstract: A portable mister for cooling ambient air is disclosed comprising a housing for entirely containing a cooling agent, an irrigation system connected to the housing for receiving the cooling agent from the housing and dispersing the cooling agent in ambient air, and a pump for facilitating the transfer of the cooling agent to the irrigation system. The mister is portable in that the cooling agent is entirely enclosed in a portable housing. That is, the mister user need not connect the mister to a continuous cooling agent source for operation. Additionally, the irrigation system is configured for placement to cool the ambient air of a broad area. The housing may include a system for including a fragrance in the cooling agent. The fragrance including system facilitates added a pleasant aroma to the dispersed cooling agent.

  • Patent number: 7331190
    Abstract: Coolant systems, for power sources (e.g. internal combustion engines, fuel cells, and nuclear reactors) or microprocessors for example, are beneficially operated with coolant in a nucleate boiling state, but transitions to damaging film boiling are then possible. The disclosed coolant system includes a sensor, such as a thermocouple or thermistor, that provides a signal representative of fluctuations in the temperature at a heated surface. The signal also includes at least one parameter. A controller processes the signal to determine changes in the parameter of the signal and/or to determine the state of the coolant and can responsively change the coolant flow to avoid undesirable coolant states. For example, coolant flow can be changed by changing the output of a coolant pump. The controller can change coolant flow automatically, or a signal can be provided to an operator that an undesirable coolant state change is imminent or has occurred, thereby allowing operator intervention.

  • Publication number: 20080028775
    Abstract: The invention relates to a method and device for establishing and maintaining defined temperature and hygrometric conditions inside premises. The method comprises the following steps: a supply reservoir (1) is filled with water; water contained in the supply reservoir (1) passes into tubes (3) or hollow profiled elements (3) of an evaporator/exchanger (2); part of the water is exuded on the outer walls of the tubes (3) or hollow profiled elements (3); a thin film of water is created on the outer walls; said film of water is subsequently evaporated, whereby the water circulating in the tubes (3) is cooled; a flow of air to be cooled is generated with the aid of ventilation means (7); the refrigerated water in said air flow is atomized with the aid of atomizing means (6) in order to create a humidified and cooled air flow.

  • Patent number: 7127907
    Abstract: A headgear capable of sprinkling and cooling comprises at least a crown, a water pouch and a liquid dispenser. The front end of the peak is provided with an atomizing nozzle, which is connected with a connecting tube at one end. A water pouch provided at the inner rim of the crown is provided with a water outlet at the outer edge. The liquid dispenser includes a squeezing device, a switch, and batteries; all of the above elements are assembled and contained in a casing composed of an upper portion and a lower portion, and then installed at an upper position of the peak. The liquid dispenser is connected to the water outlet of the water pouch with its inlet end, and to the nozzle with its outlet end via a connecting tube. Accordingly, the water contained in the pouch can be transmitted by the liquid dispenser to the nozzle at the front end of the peak for praying purpose, thereby accomplishing a headgear capable of sprinkling and cooling.

  • Patent number: 7061763
    Abstract: A novel electronics cooling method and system is disclosed. A very flexible and efficient operation of an electronics cooling system (10) is achieved by controlling circulation of a cooling medium in a closed system (40) containing an evaporator (13), a condenser (14), an ejector (11) and control valves (15–18). Specifically, the system is continuously allowed to operate in the most appropriate mode by controlling the valves (15–18) of the system (10) based on detected heat load and/or detected heat transfer conditions. By automatically adapting the mode of operation of the system based on the actual prevailing conditions, a unique flexibility is obtained with regard to the cooling mode in which the system will be operated. This means that the cooling capacity will be constantly optimized and that the investment cost as well as the cost for operating the system will be reduced compared to known systems having equal maximum cooling capacity.

  • Patent number: 6993926
    Abstract: The subject invention pertains to a method and apparatus for high heat flux heat transfer. The subject invention can be utilized to transfer heat from a heat source to a coolant such that the transferred heat can be effectively transported to another location. Examples of heat sources from which heat can be transferred from include, for example, fluids and surfaces. The coolant to which the heat is transferred can be sprayed onto a surface which is in thermal contact with the heat source, such that the coolant sprayed onto the surface in thermal contact with the heat absorbs heat from the surface and carries the absorbed heat away as the coolant leaves the surface. The surface can be, for example, the surface of an interface plate in thermal contact with the heat source or a surface integral with the heat source. The coolant sprayed onto the surface can initially be a liquid and remain a liquid after absorbing the heat, or can in part or in whole be converted to a gas or vapor after absorbing the heat.
