  • DETAILED DESCRIPTION
  • Personal cooling systems and related methods are disclosed herein. According to one aspect of the subject matter disclosed herein, a personal cooling system can include a fluid cooling chamber defining an interior for containing cooling fluid. The cooling system can also include a pump including an output nozzle, the pump being adapted to displace the cooling fluid from the interior of the fluid cooling chamber through the output nozzle. Further, the cooling system can include a fluid delivery and return structure including a heat transfer chamber adapted to be positioned in headgear such that the heat transfer chamber is positioned near one of a head and a neck of a person when the headgear is worn by the person. The fluid delivery and return structure can include a first fluid pathway adapted to deliver the cooling fluid from the output nozzle of the pump to the heat transfer chamber such that heat from the one of the head and the neck of the person is transferred to the cooling fluid within the heat transfer chamber. Further, the fluid delivery and return structure can include a second fluid pathway to deliver the cooling fluid from the heat transfer chamber to the fluid cooling chamber. This system can effectuate the cooling of a person in an overheated condition or maintain the temperature of the person at a comfortable level.
  • FIGS. 1-4 are different views of a personal cooling system in accordance with an embodiment of the subject matter disclosed herein. Particularly, FIG. 1 illustrates a perspective view of a cooling tube of a personal cooling system in use by a person wearing a helmet. FIG. 2 illustrates a top view of a cooling tube of the personal cooling system. FIG. 3 is a side cross-sectional view of a cooling chamber, pump, and portions of a cooling tube of the personal cooling system. FIG. 4 is a top cross-sectional view of the cooling chamber, pump, and portions of the fluid cooling tube of the personal cooling system. The personal cooling system is designed to reduce the temperature of the user's head and neck in order to allow a safer temperature that avoids heat-related injury. This is accomplished through reducing the heat level at the crown of the head and the arteries in the neck.
  • Referring to FIGS. 1-4, the personal cooling system can include a fluid cooling chamber 100 and a submersible water pump 102 configured to deliver cooling fluid, such as water, near the head and neck of a person. In an example, the cooling chamber 100 is a sealed tank containing a volume of water and ice. The cooling chamber 100 can define a sealed interior for containing the submersible water pump 102. The pump 102 includes an output nozzle connected to one end 103 of a supply line (or more generally a fluid delivery and return structure) 104 for pumping chilled or cool water 106 out of the tank through the line that makes its way around one side of the user's neck 108, up to the crown 110 of the head, back down to the opposite side of the neck and back to the tank. The water is returned to the interior of cooling chamber 100 via an end 111 of the supply line 104, which opposes the end 103. The returned water, warmed by heat transfer from the wearer to the water, can then be cooled within the cooling chamber's interior.
  • A cap and rubber gasket 112 can cover and seal an opening at the top of the cooling chamber 100 for preventing leaking. The cap and gasket 112 can be removed from the opening. The interior of the cooling chamber 100 can be accessed via the opening for replacing the cooling fluid, adding ice, or maintaining the pump or supply line.
  • The cooling chamber 100 is insulated and designed to be housed in a bag of any sort (e.g., a tank bag, a saddle bag, a book bag, and the like). A portion of supply line 104 can be stitched into a head cover (or headgear) to keep it in place and convenient for use. For motorcycle riders, this can be a skull cap or the like. For landscaping applications or heavy equipment operators, this can be a ball cap or other such head cover or headgear.
  • The supply line can include one or more heat transfer chambers positioned near the head and/or neck of the wearer for delivering the cooling fluid from the output nozzle of the pump to the heat transfer chamber such that heat from the head and/or neck can be transferred to the cooling fluid. For example, a portion 114 of the supply line can be positioned against or near a wearer's neck for transferring heat from the neck to the water in the supply line. Portions 114 of the supply can be stitched to a helmet 116 to maintain the portion in position near neck 108. Portions 118 of the supply line can be positioned against or near the top of a wearer's head for transferring heat from the head to the water in the supply line. For applications without a helmet or chin strap, the cooling lines can include a snap mechanism to connect the cooling lines and keep the neck wrapped. For helmets or other applications with a chin strap, the cooling tubes can be tucked under the chin strap.
  • The supply lines can be connected to the cooling chamber and the headgear with connectors, such as flexible, plastic connectors. The headgear including the supply lines can be disconnected from the cooling chamber as needed.
  • The system can be “charged” by filling cooling chamber 100 with a low level of water and then completely with ice. As the system is used and the ice melts, reducing the effectiveness of the system, the design is such that re-filling the chamber with ice will recharge the system and bring it back into a functional state instantly or soon. Excess water can be poured off at the time of recharging.
  • The water pump 102 can be a 12 Volt DC pump that can be supplied with power from any number of suitable sources depending on the application. For example, motorcycles and heavy equipment have 12 V DC leads available for this function. Landscaping equipment may require the use of different size pumps depending on the voltage and power supply available. Accommodating this will be accomplished by switching the pump and connection for the power supply depending on the client demand.
  • The water pump may be powered by any suitable power supply. For example, a solar-based power supply may be used as a source of power. In another example, a suitable battery may be used as a source of power.
  • A switch may be utilized to turn on and off the system. For example, the power to the pump may be turned off for turning off the system.
  • In one embodiment of the subject matter disclosed herein, the system may be used by more than one person. This can involve the splitting of water supply and return lines to accommodate multiple users.
  • FIGS. 5 and 6 are side and top cross-sectional views, respectively, of a personal cooling system in accordance with another embodiment of the subject matter disclosed herein. Referring to FIGS. 5 and 6, the reference numerals correspond to the same reference numerals shown in FIGS. 1-4 and described above with respect to FIGS. 1-4.
  • According to an embodiment, one or more components of the personal cooling systems disclosed herein can be attached or secured to a vehicle. The fluid cooling chamber, pump, and/or power supply may be attached to a vehicle, such as, for example, a motorcycle, lawn mower, golf cart, or the like. For example, FIG. 7 illustrates a perspective view of a motorcycle 700, its rider 702, and a bag 704 containing a fluid cooling chamber of the personal cooling system attached thereto according to an embodiment of the subject matter disclosed herein. Alternative to a bag, any suitable attachment mechanism may be used for attached or securing one or more components of the personal cooling system to a vehicle.
  • It will be understood that various details of the presently disclosed subject matter may be changed without departing from the scope of the presently disclosed subject matter. Furthermore, the foregoing description is for the purpose of illustration only, and not for the purpose of limitation.
