Description

Technical Field

[0001] This invention relates to a self-sustaining long-lasting constant temperature insulation system without external power supply and its working method. Background Technology

[0002] Currently, outdoor cold-weather clothing devices are mainly divided into four categories: electric heating insulation, disposable chemical heating patches, integrated portable heat dissipation devices, and separate liquid-medium heating clothing. They generally suffer from defects such as short battery life, large fluctuations in body surface temperature, poor concealment in the wild, difficulty in starting at low temperatures, leakage of the heating medium, and exposure of electromagnetic signals.

[0003] 1. Electric heating and cold-proof clothing relies on lithium batteries for continuous power supply. The batteries are relatively heavy, their capacity decreases significantly in low-temperature environments, and they generate electromagnetic signals when working, which is not conducive to covert operations in the field.

[0004] 2. Disposable chemical heating patches only provide heat for a few hours, and the temperature cannot be independently controlled, making it difficult to meet the needs of long-term self-sustaining operations in the field;

[0005] 3. Integrated liquid heat dissipation appliances have a fully enclosed integrated structure that cannot be disassembled and worn, and cannot provide balanced heating to the human torso and limbs in different zones;

[0006] 4. Existing split-type liquid medium wearable heating equipment uses only hollow straight-through pipes to transport the liquid medium between the liquid storage unit and the medium conversion unit, relying on electric pumps or independent mechanical throttling devices to regulate the flow rate. The hollow pipes lack a passive flow-limiting structure, and the medium transport speed cannot adaptively adjust to the reaction chamber conditions. Insufficient low-temperature liquid supply or excessive high-temperature medium can easily lead to localized overheating, resulting in uncontrollable medium consumption and significantly shortening the heating time.

[0007] 5. Traditional split heating equipment directly delivers liquid medium into the wearable layer to release heat, which is prone to leakage in the pipeline. At low temperatures, the liquid medium has poor fluidity, resulting in high heat loss and uneven heating of the body surface. Some products use a large area of ​​solid heat-conducting pad, which is heavy and restricts limb movement.

[0008] 6. Conventional liquid exothermic equipment start-up control is divided into two categories: one type is equipped with temperature sensing elements to monitor the temperature of the vaporization chamber in real time, and controls the start-up process by relying on the sensing signals. This type adds extra electronic components, increases the weight of the whole machine, and improves electromagnetic exposure characteristics. The other type does not have a preheating sequence and directly contacts the exothermic substrate upon power-on. The liquid medium comes into contact with the substrate before it is fully vaporized, which can easily lead to safety hazards such as insufficient heat release and local high temperature. The start-up success rate is low in cold environments. Summary of the Invention

[0009] This invention provides a self-sustaining long-lasting constant temperature insulation system and its working method that is completely independent of external power supply, has no continuous electromagnetic radiation, passive adaptive flow control, sensorless time-sequenced interlocking heating start-up, gaseous medium zoned distributed heat release, and is a lightweight, quick-assembly and disassembly long-lasting constant temperature wearable insulation system.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0011] A self-sustaining long-lasting constant temperature insulation system without external power supply is characterized in that: a central energy supply module is sealed and connected to a constant temperature energy conversion module through a flexible sealed sleeve; the constant temperature energy conversion module centrally vaporizes the liquid medium received by the central energy supply module; the gaseous medium undergoes initial flameless heat release conversion after contacting the heat-releasing substrate; the constant temperature energy conversion module is equipped with a preheating component and a porous main heat-releasing substrate; the constant temperature energy conversion module is also sealed and connected to a distributed wearable execution module through the flexible sealed sleeve for gaseous medium transmission; the distributed wearable execution module is also equipped with the porous main heat-releasing substrate, and undergoes secondary flameless heat release conversion after contacting the porous main heat-releasing substrate, providing heat to the corresponding area on the human body surface;

[0012] The preheating component is electrically connected to the closed-loop control feedback module via a feedback line. The closed-loop control feedback module is equipped with a touch switch to control the opening of the closed-loop control feedback module. The closed-loop control feedback module adopts timing logic. After the timing cycle ends, the preheating component is automatically turned off, and the heating operation is stopped.

[0013] The distributed wearable execution module and the constant temperature energy conversion module are respectively equipped with ignition devices, which are in contact with the porous main heat-releasing substrate inside them, for igniting the porous main heat-releasing substrate. The ignition device is also electrically connected to the closed-loop control feedback module through the feedback line for controlling the opening and closing of the ignition device.

[0014] The self-sustaining long-term constant temperature insulation system without external power supply, wherein the distributed wearable execution module, the constant temperature energy conversion module, the central energy supply module and the closed-loop control feedback module are respectively detachably fixed to the vest or combat uniform lining by buckles and Velcro.

[0015] The self-sustaining long-term constant temperature insulation system without external power supply includes: a flexible sealed sleeve containing a constrained porous fiber structure, wherein interconnected pore channels are formed inside the porous fiber structure, allowing liquid to be transported along the axial direction of the conduit by capillary force, while also allowing gas to pass freely through the pore channels;

[0016] One end of the flexible sealed sleeve is detachably and sealed to the central energy supply module via a quick-connect plug, and the other end is sealed and immersed in the constant temperature energy conversion module. The liquid medium is transmitted from the central energy supply module to the constant temperature energy conversion module for initial flameless exothermic conversion. The constant temperature energy conversion module regulates the delivery rate by the pressure generated by the gasification medium.

[0017] The distributed wearable execution module is sealed and connected to the constant temperature energy conversion module through the flexible sealed sleeve, and the heated gaseous medium is transferred from the constant temperature energy conversion module to the distributed wearable execution module for secondary flameless exothermic conversion.

[0018] The self-sustaining long-term constant temperature insulation system without external power supply includes: a vaporization chamber inside the constant temperature energy conversion module; a preheating component and a porous main heat-releasing substrate inside the vaporization chamber; a double-layer leak-proof isolation layer on the outer shell of the vaporization chamber; a heat-conducting substrate bonded inside the vaporization chamber; and heat supply evenly distributed within the chamber. The vaporization chamber is provided with multiple gaseous medium output diversion channels for sealed communication with the corresponding distributed wearable execution modules.

[0019] The self-sustaining long-term constant temperature insulation system without external power supply includes: a micro waterproof circuit board, a built-in timing program, a low-capacity micro energy storage battery, a preheating drive circuit, a heat release triggering mechanism, and a reset structure within the closed-loop control feedback module; the built-in timing program controls the opening and closing of the preheating component; the low-capacity micro energy storage battery powers the micro waterproof circuit board; the micro waterproof circuit board is electrically connected to the preheating component through the preheating drive circuit and the heat release triggering mechanism; and the reset structure is used to close the closed-loop control feedback module.

[0020] A method for operating a self-sustaining long-term constant temperature insulation system without external power supply, characterized by the following steps:

[0021] Step 1, Self-sustaining energy storage stage: Liquid medium is added to the interior of the central energy supply module. The liquid medium is a clean liquid energy at normal temperature and pressure. The central energy supply module is sealed and connected to the inlet end of the flexible sealed sleeve through a quick-connect plug. The liquid medium is passively extracted using a porous fiber structure to form a stable liquid supply channel.

[0022] Step 2, Preheating vaporization sequence start-up stage: Manually press the touch switch to start the closed-loop control feedback module and ignition device. The closed-loop control feedback module starts the preheating component in the vaporization chamber through the micro waterproof circuit board. The built-in timing program is also started at the same time. The preheating component will draw the liquid medium into the vaporization chamber for centralized vaporization.

[0023] Step 3: During the standard interlock start-up heat release stage, the preheating component fully vaporizes the liquid medium in the vaporization chamber by heating during the timing cycle. The vaporized medium comes into contact with the porous main heat release substrate and is ignited by the ignition device to form the initial flameless heat release conversion. After the timing cycle ends, the micro waterproof circuit board closes the micro waterproof circuit board through the reset structure. At the same time, the preheating component and the ignition device are also turned off, and the heating output stops.

[0024] Step 4, Waste Heat Self-Sustaining Gasification Operation Stage: After successful preheating and startup, the porous main heat-releasing substrate in the gasification chamber continues to release heat, relying on its own reaction waste heat to maintain the temperature of the gasification chamber. This allows the subsequent gasification medium to be diverted and transported to the distributed wearable execution module through a flexible sealed sleeve, where it contacts the porous main heat-releasing substrate and is ignited using an ignition device, forming a secondary flameless heat release conversion to achieve uniform and constant temperature heating for the human body in different zones.

[0025] Step 5: Passive long-term constant temperature closed-loop operation stage. During the operation of the whole system, there is no need for continuous electronic control adjustment or continuous preheating. It relies on the automatic matching of medium supply by the linkage between capillary fiber and gasification pressure to maintain a stable constant temperature range for a long time. There is no external power supply or temperature sensor involved in the control throughout the process. If the whole machine needs to be restarted after shutdown, the touch switch needs to be pressed manually again, and the preheating gasification sequence start stage and the standard interlock start heat release stage are repeated.

[0026] The beneficial effects of this invention are:

[0027] 1. Passive adaptive medium supply: It adopts a built-in polymer capillary fiber coupling structure in the pipeline. It relies on capillary adsorption + gasification pressure reverse flow restriction, eliminating the need for electric pumps and precision throttling devices. This simplifies the structure, reduces weight, eliminates continuous electromagnetic drive signals, and significantly extends the constant temperature heating time.

[0028] 2. Distributed zoned heat release of gaseous medium: The gaseous medium is first heated and vaporized, and then transported to the wearable unit for secondary heat release. This method abandons the traditional direct liquid delivery and solid heat conduction solutions, eliminating the risk of leakage, minimizing heat loss, and ensuring uniform heating of the human body surface. The flexible delivery hose does not restrict limb movement. The heat release temperature is limited by the material properties of the porous heat release substrate itself, maintaining a stable range of 50-60℃, without the need for additional temperature control components.

[0029] 3. Sensorless time-locked heating start-up: Relying on fixed power preheating + timing program to replace temperature sensor, reducing electronic components and electromagnetic exposure characteristics; After the exothermic start-up is completed, the circuit is completely de-energized, with only a short power consumption during the start-up phase. Forced heating and vaporization before starting exothermic operation significantly improves the start-up success rate in cold environments and eliminates the safety hazards caused by direct contact between liquid medium and exothermic substrate. After the equipment is working normally, it relies on the residual heat of substrate reaction to sustain vaporization, without the need for continuous power supply for heating, resulting in extremely low energy consumption.

[0030] 4. Fully modular and lightweight wearable, with four independent and detachable units, low overall weight, facilitating quick replacement and maintenance; no open flame, no high voltage, no strong electromagnetic field, strong concealment, suitable for individual soldiers and civilian cold-weather protection scenarios, and the protection range is not limited by the scenario.

[0031] 5. Self-sustaining long-term operation: Standard volume medium can maintain stable temperature for 20-30 hours with minimal temperature fluctuations. No need for mid-term liquid replenishment or external power supply. Its self-sustaining operation capability is far superior to existing insulation equipment. Attached Figure Description

Detailed Implementation

[0037] like Figures 1 to 4 The diagram illustrates a self-sustaining, long-lasting constant-temperature insulation system without external power supply. A central energy supply module 6 is sealed and connected to a constant-temperature energy conversion module 5 via a flexible, sealed sleeve 3. The constant-temperature energy conversion module 5 centrally vaporizes the liquid medium supplied by the central energy supply module 6. Upon contact with the heat-releasing substrate, the gaseous medium undergoes an initial flameless heat release conversion. The constant-temperature energy conversion module 5 is equipped with a preheating component 11 and a porous main heat-releasing substrate 12. The constant-temperature energy conversion module 5 is also sealed and connected to a distributed wearable execution module 2 via the flexible, sealed sleeve 3 for gaseous medium transmission. The distributed wearable execution module 2 also contains the porous main heat-releasing substrate 12, and undergoes a secondary flameless heat release conversion upon contact with the porous main heat-releasing substrate 12, providing heat to the corresponding area on the human body surface.

[0038] The flexible sealed sleeve 3 encloses and constrains a porous fiber structure 9. The porous fiber structure 9 forms interconnected pore channels, allowing liquid to be transported axially along the conduit by capillary force, while simultaneously allowing gas to pass freely. One end of the flexible sealed sleeve 3 is detachably and sealed to the central energy supply module 6 via a quick-connect plug 10, while the other end is sealed and immersed in the constant-temperature energy conversion module 5. The liquid medium is transferred from the central energy supply module 6 to the constant-temperature energy conversion module 5 for initial flameless exothermic conversion. The constant-temperature energy conversion module 5 regulates the delivery rate based on the pressure generated by the vaporized medium. The conversion module 5 is equipped with a vaporization chamber 13, in which the preheating component 11 and the porous main heat-releasing substrate 12 are respectively arranged. The material properties of the porous main heat-releasing substrate 12 determine that the heat release temperature range is stable at 50-60℃, without sudden temperature rises or falls. The perceived temperature after conduction to the human body surface is stably maintained at 35-45℃. The porous main heat-releasing substrate 12 is made of a catalyst material. The outer shell of the vaporization chamber 13 is a double-layer leak-proof isolation layer, and a heat-conducting substrate is bonded inside it, so that the heat supply is evenly distributed in the chamber. The vaporization chamber 13 is equipped with multiple gaseous medium output diversion channels for sealed communication with the corresponding distributed wearable execution module 2.

[0039] One end of the flexible sealed sleeve 3 is sealed and connected to the outlet end of the distributed wearable execution module 2, and the other end is sealed and connected to the inlet end of the constant temperature energy conversion module 5. The heated gaseous medium is transmitted from the constant temperature energy conversion module 5 to the distributed wearable execution module 2 for secondary flameless exothermic conversion.

[0040] The preheating component 11 is electrically connected to the closed-loop control feedback module 7 via feedback line 4. The closed-loop control feedback module 7 is equipped with a touch switch 8 to control its opening. The closed-loop control feedback module 7 uses timing logic; after the timing cycle ends, it automatically shuts down the preheating component 11 and stops the heating operation. The closed-loop control feedback module 7 contains a micro waterproof circuit board, a built-in timing program, a low-capacity micro energy storage battery, a preheating drive circuit, a heat release trigger mechanism, and a reset structure. The built-in timing program controls the opening and closing of the preheating component 11. The low-capacity micro energy storage battery powers the micro waterproof circuit board. The micro waterproof circuit board is electrically connected to the preheating component 11 via the preheating drive circuit and the heat release trigger mechanism. The reset structure is used to shut down the closed-loop control feedback module 7.

[0041] Ignition devices are respectively installed in the distributed wearable execution module 2 and the constant temperature energy conversion module 5, and are in contact with the porous main heat-releasing substrate 12 installed therein, for igniting the porous main heat-releasing substrate 12. The ignition device is also electrically connected to the closed-loop control feedback module 7 through the feedback line 4 for controlling the opening and closing of the ignition device.

[0042] The distributed wearable execution module 2, the constant temperature energy conversion module 5, the central energy supply module 6, and the closed-loop control feedback module 7 are detachably fixed to the vest 1 or the combat uniform lining by buckles and Velcro.

[0043] A method for operating a self-sustaining long-term constant temperature insulation system without external power supply, characterized by the following steps:

[0044] Step 1, Self-sustaining energy storage stage: Liquid medium is added to the interior of the central energy supply module 6. The liquid medium is a clean liquid energy at normal temperature and pressure. The central energy supply module 6 is sealed and connected to the inlet end of the flexible sealed sleeve 3 through the quick connector 10. The liquid medium is passively extracted using the porous fiber structure 9 to form a stable liquid supply channel.

[0045] Step 2, Preheating vaporization sequence start stage: Manually press the touch switch 8 to start the closed-loop control feedback module 7 and ignition device. The closed-loop control feedback module 7 starts the preheating component 11 in the vaporization chamber 13 through the micro waterproof circuit board. The built-in timing program is also started at the same time. The preheating component 11 will draw the liquid medium into the vaporization chamber 13 for centralized vaporization.

[0046] Step 3: During the standard interlock start-up heat release stage, the preheating component 11 fully vaporizes the liquid medium in the vaporization chamber 13 by heating during the timing cycle. The vaporized medium comes into contact with the porous main heat release substrate 12 and is ignited by the ignition device to form the initial flameless heat release conversion. After the timing cycle ends, the micro waterproof circuit board closes the micro waterproof circuit board through the reset structure. At the same time, the preheating component 11 and the ignition device are also turned off, and the heating output stops.

[0047] Step 4, Waste Heat Self-Sustaining Gasification Operation Stage: After successful preheating start-up, the porous main heat-releasing substrate 12 in the gasification chamber 13 continues to release heat, relying on its own reaction waste heat to maintain the temperature of the gasification chamber 13. This allows the subsequent gasification medium to be diverted and transported to the distributed wearable execution module 2 through the flexible sealed sleeve 3, where it contacts the porous main heat-releasing substrate 12 and is ignited using an ignition device, forming a secondary flameless heat release conversion, and achieving uniform constant temperature heating for human body zones.

[0048] Step 5: Passive long-term constant temperature closed-loop operation stage. During the operation of the whole system, there is no need for continuous electronic control adjustment or continuous preheating. It relies on the automatic matching of medium supply by the linkage between capillary fiber and gasification pressure to maintain a stable constant temperature range for a long time. There is no external power supply or temperature sensor involved in the control throughout the process. If the whole machine needs to be restarted after shutdown, the touch switch 8 needs to be pressed manually again, and the preheating gasification sequence start stage and the standard interlock start heat release stage are repeated.
