An exemplary hot material includes hot water. The fluid inside the insulated fluid reservoir is separated from the heat transfer fluid, however, the fluid is able to conduct heat between the fluid in the reservoir and the heat transfer fluid. The insulated fluid reservoir is insulated from surrounding atmosphere to minimize heat loss to the surroundings.
The fluid-enabled article 104 may be any kind of fluid enabled article discussed herein, such as a vest, a jacket, pants, socks, a hat, a glove, a blanket, or the like.
The fluid conditioning system 106 receives power from an external power supply, and acts to heat or cool the heat transfer fluid. The heat transfer fluid may be water, anti-freeze, or any other suitable fluid capable of carrying heat through the personal climate system.
The control manifold 108 directs flow of heat transfer fluid to the fluid enabled article 104. The connections between the flow control manifold are break-away couplings, designed to release under tension. The flow control manifold may comprise connections for one or many different fluid conveyance enabled articles. Each connection to a fluid conveyance enabled article comprises an inlet and an outlet to direct flow of the heat transfer fluid to and receive flow of heat transfer fluid from each of the fluid conveyance enabled articles.
The heat transfer fluid circulates through the system 100. An exemplary flow path is from the inline pump, clockwise to the fluid conditioning system, down to the control module. In the control module, via the flow control manifold, the heat transfer fluid is directed to the connected fluid conveyance enabled articles and returns to the flow control manifold and proceeds clockwise to return to the pump.
In some embodiments, the heat transfer fluid circulates between one of two flow paths. A first flow path is from the fluid reservoir 102, through tubing 112, through the control manifold 108, through tubing 114, through the fluid-enabled article 104, through the tubing 116, through the control manifold 108, and return to the fluid reservoir 102 through the tubing 118.

The flow control manifold 108 may be used to configure the system between one of the two flow paths
In some embodiments, the system may also include an inline pump and a battery. In the system 100, the battery is connected to the control manifold via electrical connections. The battery can be a rechargeable battery, may be made of NI-MH, standard single use alkaline batteries (AA, AAA, C, D, 9 v, etc.), lithium, graphene, or any other battery suitable as a power supply, as know by those with skill in the relevant art. The battery is connected to control module, and serves as a power supply to the pump and the control module. In some embodiments, the battery supplies power to the pump when an external power supply is not connected, and does not supply power to the pump when an external power supply is connected.
In accordance with an embodiment, a cover is attached on top of the fluid bock. The cover serves as a heat transfer surface, and serves as a connection point for a heating or cooling element.
The view 220 depicts the base with the nozzles and cover removed. The base comprises a series of grooves which serve as the flow path 208. The heat transfer fluid enters in through one of the nozzle holes 204, traverses through the grooves (flow path 208), and exits through the other nozzle hole 206.
In some embodiments, the heating or cooling element is a thermo-electric tile. The thermo-electric tile, also known as a Peltier tile, is capable of producing heat on one side and cold on the opposite side when a voltage is applied across the tile. In an exemplary personal climate system, a thermo-electric tile is coupled to the cover of the fluid block, with thermally conductive adhesive, or by other methods as known by those with skill in the art. A heat sink can be attached, via similar methods, to the opposite surface of the thermo-electric tile. The heat sink removes heat from the thermo-electric tile.
The thermal-conditioning system may also incorporate vents to provide improved heat transfer. The vents may be positioned on the top, the front, and the sides of a thermal-conditioning system enclosure.
The heat sink can be any one chosen by one with skill in the relevant art, but may include a heat sink with straight pins, or may be a pin fin style.
The example system shown in
In accordance with an embodiment, heat transfer fluid is circulated through the flow paths via a pump. The pump comprises electrical connections, an inlet nozzle, an outlet nozzle, and a power supply cord. The power supply cord receives power from either the external power supply or the internal battery. When the personal climate system is connected to an external power supply, such as a motorcycle, snow-mobile, fork-lift, automobile, and the like, the battery does not supply power to the pump. The housing may be water and dust ingress protected.
The insulated fluid reservoir 502 comprises the fill cap 506, internal flow pipes 508, and a connection point 510. The insulated fluid reservoir 502 is filled with either hot or cold fluid, or similar materials through the fill cap 506. The heat transfer fluid is able to flow through the insulated fluid reservoir 502 to conduct heat transfer with the fluid inside the insulated fluid reservoir 502.
The fluid reservoir 502 may be an aluminum or stainless-steel hard sided bottle. The fluid reservoir may have a cap, the cap comprising a plurality of barbed nipples. A first barbed nipple for outlet to the pump and a second barbed nipple from the return inlet from heat-transfer fluid circulated through the fluid-enabled articles. In some embodiments, the barbs on the nipples will be recessed barbs, configured to reduce risk of pinching tubes and restricting flow.
The system 500 also comprises the intensity control 512 and the mode selector switch 514. The intensity control controls the amount of heat to be transferred to the fluid conveyance articles. The mode selector switch comprises an off position, a cool position, and a heat position.
In circumstances that the personal climate system is operating on external power, and the mode control selector switch 514 is set to cool, the heat transfer fluid circulates through the fluid block to cool the heat transfer fluid, circulates through connection point 510, and flows through the insulated fluid reservoir 502 at point 510. The heat transfer fluid conducts relatively small amount of heat to the fluid in the insulated fluid reservoir, and may slightly cool the water inside the reservoir 502 before flowing through connection point 510 to the fluid conveyance articles 518.
The system may include a control panel, in accordance with an embodiment. The example control panel comprises at least an intensity selector and a mode control selector. The selectors are depicted as circular knobs and are situated on a housing that encloses the thermal conditioning module and flow control manifold.
In embodiments with the intensity selector control, the intensity selector control is configured to control the intensity of the heating or cooling supplied to the fluid conveyance articles. The intensity control switch controls the level of heat or cooling power provided by the fluid-conditioning system. It may control the magnitude of the voltage across the TEC tile, or may control the number of the TEC tiles that receive voltage. The intensity control switch may also be configured to control the volumetric flow rate through the pump. Raising the setting on the intensity control switch increases the flow rate of the heat transfer fluid through the pump, and thus the flow rate of the heat transfer fluid through the fluid enabled articles.
The control panel may also comprise other control elements. The control panel can be configured to control power to the pump and the thermal conditioning system portions of the personal climate system. In some such embodiments, the control panel determines electrical power available and supplies electricity to the various components of the personal climate control system. When the control panel detects an external power supply, the control panel directs electrical power to the fluid conditioning device and the pump. When the external power supply is not detected, such as by a change in voltage, or lack of voltage, or in other methods known by those in the art, the control panel directs electrical power to the pump and does not supply power to the thermal conditioning system.
In various embodiments, the control panel also is a weather (water and dust) proof enclosure. The control panel may also provide indicating lights, auxiliary power supplies (such as a USB port for a phone, may be wirelessly or wired communicatively to a separate user interface as known by those with skill in the art. In embodiments that comprise a separate user interface, the separate user interface may be a wired control extender, the control extender to allow a user to place the controls in a more convenient location, or it may be a wireless connected user interface, such as through a Bluetooth connection to a personal smart phone, a network server, or the like. The wireless interface may be able to receive commands to control the personal climate system through voice control, through the vehicle's integrated controls, or the like.
In accordance with an embodiment, some of the interconnecting valves disconnect under tension force. Example tensile forces that the connections disconnected should be between 10 to 15 lbs of pressure. Example interconnections include the connection points between the flow control manifold and the tubing connected to the fluid conveyance articles. In various embodiments, the valves that disconnect under tension are the connection points between the cooling/heating unit, the control panel, the reservoir, and the fluid enabled articles.
In accordance with an embodiment, the personal climate control system includes auxiliary power connectors to connect an auxiliary reserve battery. The auxiliary reserve battery is used to power at least the pump of the exemplary personal climate control system.
In accordance with an embodiment, the exemplary personal climate control system comprises detachable back-pack straps.
The above elements may be combined by those with skill in the relevant art to provide methods of a micro-climate system. In an exemplary method, a heat transfer fluid is circulated through a fluid conditioning system. When the fluid conditioning system is connected to an external power supply, the heat transfer fluid is thermally conditioned, either heated or cooled based on the position of a mode control selector switch. The rate of heating or cooling is determined based on a position of a thermostat, or intensity selection control.
The heat transfer fluid is also circulated through an insulated fluid reservoir. The insulated fluid reservoir is insulated from the outside surroundings and is capable of transferring heat to and from the heat transfer fluid being circulated through the insulated fluid reservoir. The insulated fluid reservoir is filled with either a hot fluid (e.g., hot water) or a cold fluid (e.g., cold water, ice, dry ice) The fluid in the fluid reservoir serves as an additional source of heat or cooling, and is able to heat or cool the heat transfer fluid or is able to be heated or cooled by the heat transfer fluid.
The heat transfer fluid is also circulated through a fluid enabled article. Exemplary fluid enabled articles include vests, hats, pants, blankets, gloves, boots, and the like. The fluid enabled articles comprise a network of tubing that permits heat transfer between the heat transfer fluid and a user of the fluid enabled article.
The fluid conditioning system, the insulated fluid reservoir, and the fluid enabled articles are interconnected via a first tubing system. The first tubing system comprises disconnects that detach under sufficient tensile force. A sufficient tensile force is approximately 10-15 lbs.
In one embodiment, the method for providing cooling comprises circulating a heat transfer fluid, via a pump powered by a battery, through a first flow path. The first flow path comprises a fluid reservoir and a fluid enabled article. In such a method, the heat transfer fluid transfers heat to a material within the fluid reservoir and from a fluid enabled article to provide cooling.
The method for providing cooling further comprises circulating a heat transfer fluid, via a pump, through a second flow path. The second flow path comprises a fluid conditioning system, a fluid reservoir, and a fluid enabled article. In such a method, the fluid conditioning system receives power from an external power supply, such as from a motorcycle or vehicle. The thermal conditioning system cools the heat transfer fluid, which flows to the fluid enabled articles. The heat transfer fluid returns to the fluid conditioning system.
This method for providing cooling permits a user to decouple the fluid conditioning system from the fluid reservoir while receiving cooling via flow through the first flow path. The fluid reservoir is portable and able to be carried on a user. A user may then restore cooling via the thermal conditioning system by recounting the fluid conditioning system to form the second flow path.
A complimentary method to the one disclosed above for providing cooling may be used to provide heating. The opposite method involves receiving heat from the fluid reservoir and transferring heat to the fluid enabled article when the articles first flow path is used and receiving heat from the thermal conditioning system and transferring heat to the fluid enabled article when the articles are connected to the second connection point.
