Description

Personal cooling and heating systems

Background technique

There are no acceptable prior art heat stress and cold weather exposure mitigation systems for individuals such as soldiers who work in hot and cold environments for extended periods of time. Desert conditions, for example, often expose individuals to heat stress during daytime hours and severe cold at night. Heat stress can cause sweating, fatigue, dehydration, dizziness, excessive skin temperature, muscle weakness, increased heart rate, heat rash, fainting, injury, weight loss, heat stroke, heat exhaustion, and even death. The danger of heat stress is even greater for those individuals wearing nuclear, biological and chemical (NBC) protective suits, as well as for crew members in flight suits. Cold weather exposure can cause: discomfort; pain; numbness; heart, circulation and breathing problems; decline in muscle function and performance; frostbite and hypothermia that can lead to unconsciousness and death.

Although portable, lightweight, low-power personal cooling and heating systems can reduce heat stress, reduce the adverse effects of cold exposure, improve work performance, and reduce water consumption, existing active and passive cooling systems fail to meet the Minimum requirements for an optimal system.

Active personal cooling devices are known in the art. Active personal heating systems are also known in the prior art. However, the prior art appears to lack a combined cooling and heating system that operates at any high efficiency for extended periods of time. However, existing active cooling and heating systems are cumbersome, bulky, inefficient, and only effective for a limited amount of time. These devices also consume too much energy and use potentially dangerous substances such as lithium sulfur dioxide batteries or R134a refrigerant. Passive cooling and heating systems that use packaging containing phase change chemicals, water or gels that require cooling, freezing or heating before use are not suitable to meet the needs of users in situations such as Military field operations in hot, cold or a combination of hot and cold climates where cooling, freezing or heating of passively cooled or heated components is not possible. State-of-the-art active cooling and heating systems that have been developed include:

1. Problems with the US Military PICS (Personal Ice Cooling System): This system uses dense ice. The ice must be changed every 30 minutes, and users such as pilots and soldiers deployed in the field may not have access to ice to replenish the system.

2. Problems with US military PVCS (Portable Vapor Compression Cooling System): The whole system is too bulky (27 lbs); uses potentially dangerous lithium sulfur dioxide batteries, cannot use vapor compression on non-horizontal surfaces such as ships; R134a containers may rupture at high temperatures , Exposure to liquid or vapor refrigerants can cause frostbite, and high exposure to gas can cause central nervous system weakness, irregular heartbeat and suffocation.

3. Problems with ALMCs (Advanced Lightweight Microclimate Cooling System) used by the US military: voltage delays may prevent lithium sulfur dioxide batteries from starting, especially after storage; batteries may leak toxic sulfur dioxide gas that can cause breathing difficulties, and in case of accidents May burn if charged, punctured, or if heat is applied. These batteries are not rechargeable, cannot be exposed to high temperatures, react readily with water, and cannot be opened, punctured, or crushed.

4. IMCC (Integrated Medium Cooling Loop) (DARPA US Defense Advanced Research Projects Agency) problem: Inadequate cooling.

5. Problems with Absorption/Evaporative Cooling (DARPA: According to Roger Masadi of the Natick Soldier Center, typical desiccants only absorb about 20% of their weight in water, while cooling is roughly as dense as ice same.

6. Problems with NASA and USAF (APECS) aircrew personal environmental control systems: These systems are too bulky for infantry soldiers.

7. Problems with life-enhancing technology: The ice-water mixture used to cool the unit had to be replenished.

While each of these prior art personal cooling and heating systems can fulfill their own particular purposes and needs, and are likely to be quite useful for their intended use, it is noted that the prior art None of the art discloses devices and/or methods that are portable, strong and lightweight and can be used in any orientation or used as a belt mounted system or backpack to meet the operational requirements of the user. Furthermore, the prior art cannot provide continuous hours of operation at adjustable cooling or heating rates of 700-1000 British Thermal Units (BTU) per hour.

In this regard, there is clearly a need for a new and improved personal cooling and heating system that maximizes the benefit to the user and minimizes the risk of injury resulting from its use.

In this regard, the invention disclosed herein substantially corrects these problems and fulfills the need for such a device.

The cooling unit power supply weighs 4 pounds, while the heating unit power supply weighs 3 pounds more than the cooling unit power supply to heat 700 British thermal units (BTU) in two full hours. The system design will determine whether the battery assembly is mounted on the main unit or as a separate component.

4) Vest (21):

In the preferred embodiment as depicted in Figures 2, 6, 7, 8, 9 and 10, the system will be used with a vest (21) containing tubes or channels through which cooling/heating fluid can flow These tubes or channels. The vest (21) is equipped with quick release hoses and fittings (25) to allow the user to remove the cooling and heating units without taking off the vest (21). The vest (21) weighs approximately two pounds including fluids and connectors. The cooling unit circulates a water-based heat exchange fluid through tubes inside the vest (21). The liquid warmed by the user's body leaves the vest (21) by being pumped into the vest circuit liquid heat exchanger (2A) by the vest circuit pump (23B). Channels within the liquid heat exchanger frame (2) direct the warmed liquid so that it contacts the nine reversible thermoelectric cooler (TEC) modules (1), thereby transferring heat from the liquid to the nine reversible thermoelectric cooler (TEC) modules (1). The cold side of the thermoelectric cooler (TEC) module (1 ) forming the side of the vest loop liquid heat exchanger (2A). Heat is transferred from this liquid directly to the cold side of the nine reversible thermoelectric cooler (TEC) modules (1). The perliti ( ) junctions within these nine reversible thermoelectric cooler (TEC) modules (1) transfer heat from the cold side of the reversible thermoelectric cooler (TEC) module (1) to the reversible thermoelectric cooler (TEC) module ( 1) The hot side. Heat from the hot side of the reversible thermoelectric cooler (TEC) module (1) is transferred to the cooling loop liquid heat exchanger (2B). When the cooling liquid circulates through the cooling circuit liquid heat exchanger (2B), the cooling circuit liquid heat exchanger (2B) transfers heat to the cooling liquid. The air heat exchanger (11) is located on both sides of the cooling circuit liquid heat exchanger (2B). When the cooling liquid circulates through the cooling liquid channel (26) of the air heat exchanger, the cooling liquid carries heat to the two air heat exchangers (11) and transfers the heat to the air heat exchanger (11). An air heat exchanger fan (16) located at the top of each air heat exchanger (11) in these air heat exchangers (11) blows ambient air through the air heat exchanger air channels (27) to provide heat exchange to the air Forced convection cooling of the device (11). The heat is transferred to the ambient air and extracted from the bottom of the air heat exchanger (11). The cold side of the reversible thermoelectric cooler (TEC) module (1) maintains the liquid inside the vest (21) at a cooling temperature desired by the user, which is set by the user on the microcontroller, display and keypad (19).

The composition and operation of the device as depicted in the accompanying drawings are as follows:

1. Reversible Thermoelectric Cooler (TEC) Module (1)

A reversible thermoelectric cooler (TEC) module (1 ), also known as a Peltier device, is a small device used as a heat pump. A reversible thermoelectric cooler (TEC) module (1) typically consists of a small bismuth telluride cube sandwiched between two ceramic plates. When direct current is applied to one of the reversible thermoelectric cooler (TEC) modules (1), heat moves from one side of the TEC module to the other. To generate greater efficiency and reduce the size and weight of the Personal Cooling and Heating Unit (PCHU) (22), the nine reversible thermoelectric coolers The cold side of the (TEC) module (1) forms the side of the vest loop liquid heat exchanger (2A), while the hot side of the nine reversible thermoelectric cooler (TEC) modules (1) form the cooling loop liquid heat exchanger ( 2B) side. For maximum efficiency, the reversible thermoelectric cooler (TEC) module (1) is activated by a reversible direct current pulsed by the microcontroller, display and keypad (19), the electrical energy for which is supplied by the battery power supply (20 )supply.

2. Vest loop liquid heat exchanger (2A) and cooling loop liquid heat exchanger (2B)

In this preferred embodiment, each of the vest loop liquid heat exchanger (2A) and the cooling loop liquid heat exchanger (2B) is cooled by a liquid heat exchanger frame (2) and nine reversible thermoelectric These nine reversible thermoelectric cooler (TEC) modules (1) form the sides of the cooling loop liquid heat exchanger (2B) and the vest loop liquid heat exchanger (2A). For cooling, the warm liquid leaving the vest (21) is circulated through the vest loop liquid heat exchanger (2A) and cooled by direct contact with the cold side of the nine reversible thermoelectric cooler (TEC) modules (1) . For heating, the cold liquid leaving the vest (21) is circulated through the vest loop liquid heat exchanger (2A) and heated by direct contact with the hot side of the nine reversible thermoelectric cooler (TEC) modules (1) . Initially the liquid heat exchanger frame (2) will be manufactured from plastic, but may be constructed from any suitable material. The liquid heat exchanger frame (2) can be divided into two separate channels from which the two cooling circuit pumps (23) draw cooling liquid and finally return the cooling liquid to each separate channel. This design provides a more efficient rate of heat transfer from liquid to liquid heat exchanger (2).

3. Vest circuit pump (23B) and cooling circuit pump (23)

In one closed loop, the vest circuit pump (23B) circulates the liquid through the vest circuit liquid heat exchanger (2A) and the vest (21), while in the other closed loop, the cooling circuit pump (23) circulates the liquid Pass through the cooling circuit liquid heat exchanger (2B) and the air heat exchanger cooling liquid channels (26) in the two air heat exchangers (11). As depicted in Figure 4, the vest circuit pump (23B) and cooling circuit pump (23) are designed with two gears. A variable speed brushless DC motor will power one gear which drives the other, providing precise management of the cooling/heating fluid circulation.

4. Air heat exchanger (11)

The air heat exchanger (11) is installed in the personal cooling and heating unit (PCHU) (22) containing the nine reversible thermoelectric cooler (TEC) modules (1), vest circuit liquid heat exchanger (2A) and cooling circuit The opposite side of the liquid heat exchanger (2B) inside. Each air heat exchanger (11) is cylindrical, and air heat exchanger cooling liquid passages (26) and air heat exchanger air passages (27) are formed therein. The air heat exchanger coolant channel (26) consists of a series of circular holes around the top perimeter of the air heat exchanger (11), extending vertically to the bottom of the air heat exchanger (11). When used as a cooling device, liquid warmed by the user's body is pumped from the vest through the vest circuit liquid heat exchanger (2A). The liquid is cooled as it passes through the vest circuit liquid heat exchanger (2A). A reversible thermoelectric cooler (TEC) module (1) provides cooling to the vest circuit liquid heat exchanger (2A). The cooling loop liquid heat exchanger (2B) removes heat from the reversible thermoelectric cooler (TEC) module (1). The air heat exchanger (11) absorbs heat from the cooling circuit liquid heat exchanger (2B). When two air heat exchangers are used, each air heat exchanger (11) absorbs half of the heat from the side of the cooling circuit liquid heat exchanger (2B) corresponding to the air heat exchanger (11), and the cooling circuit liquid heat The exchanger (2B) consists of two separate individual channel liquid heat exchangers (2) and said nine reversible thermoelectric cooler (TEC) modules (1). In a closed circuit, liquid from a separate channel of the cooling circuit liquid heat exchanger (2B) is pumped down by a cooling circuit pump (23) through an air heat exchanger in the air heat exchanger (11) The air heat exchanger coolant channel (26) of the device (11). The liquid follows the air heat exchanger coolant channel (26) down the length of the air heat exchanger (11) tank and then up and down the interior of the air heat exchanger (11) tank. The liquid is then drawn from the bottom of the tank of the air heat exchanger (11) and returned to the cooling circuit liquid heat exchanger (2B). Similarly, in a closed circuit, liquid from another separate chamber of the cooling circuit liquid heat exchanger (2B) is pumped down by the second cooling circuit pump (23) through the opposite air heat exchanger ( 11) The air heat exchanger cooling liquid channel (26), the air heat exchanger cooling liquid channel (26) is located at the top of the opposite air heat exchanger (11). Liquid follows the air heat exchanger coolant channel (26) of the opposing air heat exchanger (11) down the length of the tank of the opposing air heat exchanger (11) and then around the opposing air heat exchanger (11) The inside of the tank of the exchanger (11) goes up and down. Liquid is then drawn from the bottom of the tank of the opposing air heat exchanger (11) and returned to the cooling loop liquid heat exchanger (2B).

5. Air Heat Exchanger Fan(16)

The air heat exchanger fan (16) is a variable (0-180) CFM fan for providing forced convection cooling through the air heat exchanger air channels (27) of the air heat exchanger (11). The air heat exchanger fan (16) will be powered by a 16mm diameter Maxon brushless fan motor (13). In the best mode, the air heat exchanger fan (16) will be made of high temperature plastic. The air heat exchanger fan (16) and the brushless fan motor (13) will be installed at the center of the top of the air heat exchanger (11).

The air heat exchanger fan (16) pushes ambient air through the holes including the air heat exchanger air channels (27) at the top and through the tank of the air heat exchanger (11). These holes are located inside the perimeter of the circular hole including the air heat exchanger coolant channels (26) and extend vertically from the top through the bottom of the air heat exchanger (11) tank. The air heat exchanger fan (16) will push air down through the air heat exchanger air channels (27) of the air heat exchanger (11) and out the bottom of the air heat exchanger (11) tank, thereby creating effective airflow and Heat excluded. As the air flows through the air heat exchanger (11), heat is transferred to or from the ambient air.

6. Controller

The microcontroller, display and keypad (19) are mounted on top of the vest circuit liquid heat exchanger (2A) and the cooling circuit liquid heat exchanger (2B). The microcontroller, display and keypad (19) monitors the remaining capacity of the battery power supply (20) and obtains measurements from 17 temperature sensors (3) located in: 1) connected to the air heat exchange (11) in each of the four tubes of the cooling loop liquid heat exchanger (2B); 2) on the hot and cold sides of the reversible thermoelectric cooler (TEC) module (1); 3) the vest loop liquid heat exchanger (2A) with liquid heat exchanger (2B) for cooling circuit; 4) two air heat exchangers (11); 5) vest (21) and liquid heat exchanger (2A) for vest circuit with In the liquid inlet and outlet of the cooling circuit liquid heat exchanger (2B).

By monitoring these temperatures, the microcontroller, display and keypad (19) will select the dynamic configuration required for optimal cooling and heating. The microcontroller, display and keypad (19) will read the desired level of heating or cooling specified by the user via the temperature selector (24) and provide that precise amount of cooling or heating. The user will manually set the thermostat to the desired temperature with a number in the 700-1000 BTU range.

Microcontroller, display and keypad (19) will control cooling circuit pump (23), vest circuit pump (23B), air heat exchanger fan (16) and brushless fan motor (13), and reversible thermoelectric cooler ( TEC) module (1), to provide the most effective cooling and heating for the liquid flowing through the vest (21). heating

The temperature of the liquid must reach a minimum of 100 degrees Fahrenheit, and preferably 110 degrees Fahrenheit, to provide sufficient heating that the nine reversible thermoelectric cooler (TEC) modules (1 ) alone cannot generate. The operational components required during heating will be: the nine reversible thermoelectric cooler (TEC) modules (1); flexible heating wires (8) or fuel burners; a vest loop liquid heat exchanger (2A); a vest Loop pump (23B); microcontroller, display and keypad (19); and vest (21). The cooling unit will be switched off during the heating period.

Odorless, clean burning, smokeless liquid fuels such as liquid gasoline, pure unleaded gasoline or lighter fluids may be used in fuel burning embodiments as a replacement for the flexible heating wire (8). The burners will be mounted on the vest circuit liquid heat exchanger (2A) connected to the vest (21). The disadvantages of using this burner are that the user will need to carry a flammable liquid, will have to light the burner to ignite the burner, and the vest (21) must be worn over the user's other clothing, making it unsuitable for hazardous substances protective suit. It is possible to design a burner with electronic ignition and control that would not require the user to manually fire the burner on or off. This design will provide the most heat for the weight of the system, but is potentially very hazardous for use in activities such as airport maintenance work area maintenance, which are often performed in close proximity to aircraft fuel vapors.

7. Heating wire(8)

The flexible heating wire (8) is an electric heater connected to the cold side of the nine reversible thermoelectric cooler (TEC) modules (1) comprising the operatively reversible side of the vest loop liquid heat exchanger (2A).

When the user sets the invention to deliver heat to the device, the flexible heating wire (8) heats the sides of the nine reversible thermoelectric cooler (TEC) modules (1) that include the vest loop liquid heat exchanger (2A) The cold side of the , through the nine reversible thermoelectric cooler (TEC) modules (1) raise or increase its heat, which then heats the included vest with the nine reversible thermoelectric cooler (TEC) modules (1) The hot side of said side of the loop liquid heat exchanger (2A) contacts the liquid, and the vest loop pump (23B) will then circulate the heated liquid up through the vest (21), warming the user. The present invention can be made such that the area and size of the vest circuit liquid heat exchanger (2A) can be varied, allowing precise adjustment of the vest (21) temperature through constant temperature and electronic control.

8. Battery power

The battery power source (20) is a currently available battery pack of rechargeable lithium-ion cells weighing 4 pounds and supplying 7.2 volts to provide at least two hours of continuous operation. The rechargeable battery pack of battery power (20) has a one hour recharge cycle time. Currently available non-rechargeable batteries and disposable fuel cells can provide continuous operation with less weight or longer runtime up to 6.5 hours. For example, a 3 volt lithium/manganese dioxide cell weighs 0.242 lbs/cell. For 4 hours of cooling, 10 batteries will be used with a total weight of 2. lbs. For 6.5 hours of cooling, 16 batteries will be used for a total weight of 3.88 lbs. A 5.2 volt zinc/air fuel cell weighs 1.7 lbs/cell. For 4 hours of cooling, 14 batteries will be used for a total weight of 2.38 lbs. For 6.5 hours of cooling, 22 batteries will be used for a total weight of 3.74 lbs. However, neither lithium/manganese dioxide nor fuel cell stacks are rechargeable.

Battery technology continues to improve, and manufacturers of rechargeable, non-rechargeable, and fuel cells have announced that by the end of 2003 they will offer products that weigh 50 percent less and have two to three times the performance of their current products products, which may reduce the size and weight of the invention by 35%.

Figure 3 illustrates the specific structure of the reversible thermoelectric cooler (TEC) modules (1), which will provide 125 watts of cooling for an electrical power input of 46 watts. For the reversible thermoelectric cooler (TEC) module (1) of this structure, the coefficient of performance is 270%.

II. Detailed Description of the Evaporative Cooling Embodiment:

An evaporative cooling embodiment of the prior invention is generally depicted in FIGS. 6 and 7 . The most preferred embodiment is used in each of these evaporative cooling embodiments except that the vest loop liquid heat exchanger (2A) is replaced by a condenser loop liquid heat exchanger (2C) that is divided into two chambers cooling unit. Two separate condenser fluid pumps (23A) draw heated condenser fluid through their own separate condensing coils (37) within their own vest air cooler and condenser (28) and transfer the heated The condenser fluid is pumped into each separate chamber of the condenser loop liquid heat exchanger (2C), so that the heated condenser fluid forms a condenser loop with the nine reversible thermoelectric cooler (TEC) modules (1) The cold sides of the sides of the liquid heat exchanger (2C) are in direct contact, allowing the condenser fluid to cool before being pumped back through the condensing coil (37).
