Description

Technical Field

[0001] This invention relates to the field of wearable cooling devices, and in particular to an outdoor distributed heat absorption unit dual-mode wearable human body cooling device. Background Technology

[0002] This device can be used in all outdoor high-temperature work scenarios as a wearable human body cooling device to alleviate the problems of stuffiness, heatstroke, and high temperature burns on the skin when working outdoors under the sun.

[0003] Existing outdoor wearable cooling devices are limited in function, only capable of either water cooling or air-cooling. Outdoor workers need to purchase multiple sets of equipment depending on the duration of their work, resulting in high operating costs. The two types of equipment have independent piping structures, making them incompatible for switching. If air-cooling pipes are equipped with air vents, salt water leakage can easily occur during water operation, wetting the skin. If air-cooling pipes lack a corresponding sealing structure, they cannot accommodate liquid media circulation. Marketed products lack a sealing structure that allows for rapid switching of media; switching cooling modes requires replacing the entire main piping of the device, which is cumbersome, results in significant wear and tear on parts, and makes it difficult to adapt to diverse outdoor conditions such as long working hours and short periods of intense sweating. Wearable cooling devices have poor versatility, failing to meet the dual needs of continuous heat absorption and breathable heat dissipation, thus significantly limiting their practicality. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an outdoor distributed heat absorption unit dual-mode wearable human body cooling device, which solves the problems of existing outdoor wearable cooling devices having only a single cooling mode, being incompatible with water and air media, requiring the replacement of the entire pipeline when switching modes, being prone to leakage, having poor versatility and high operating costs.

[0005] This invention also provides a dual-mode wearable human body cooling device with an outdoor distributed heat absorption unit, comprising several circulation pipes, several connecting straps, and several connecting pipes; the circulation pipes are arranged vertically at equal intervals, with connecting straps fixed between adjacent circulation pipes and connecting pipes connecting adjacent circulation pipes; a shell is fixedly provided on the back side of each circulation pipe, with a delivery pipe and a return pipe respectively connected to both sides of the shell, the delivery pipe being connected to the uppermost circulation pipe and the return pipe being connected to the lowermost circulation pipe; the shell is equipped with a medium supply mechanism, which is used to deliver cooling medium into the circulation pipes to achieve wearable cooling of the human body, and is widely applicable to summer operations in the military, oil fields, construction, farmland, road construction, and urban and rural residents' outdoor work and life scenarios in summer.

[0006] The inner walls of both the delivery pipe and the return pipe are fixed with semiconductor cooling plates for cooling the medium inside the pipes.

[0007] In one technical solution, the medium supply mechanism includes two connectors and two expansion joints; the two connectors are respectively fixed to the inner walls of both sides of the housing and are respectively connected to the delivery pipe and the return pipe, and the two expansion joints are respectively sealed and sleeved on the outer walls of the corresponding connectors.

[0008] The circulating medium inside the circulation pipe, connecting pipe, conveying pipe, and return pipe is cooling brine, and a valve is embedded below the bottom of the circulation pipe.

[0009] In another technical solution, the medium supply mechanism further includes a micro water pump; flanges are fixedly mounted on the outer walls of one end of each of the two expansion joint pipes, and the micro water pump is detachably connected between the two expansion joint pipes through two sets of flanges to drive the circulation of cooling brine inside the pipeline.

[0010] The medium supply mechanism includes a cover plate, a flange ring, and a fan; the cover plate is detachably sealed to the upper part of the housing, the flange ring is embedded inside the cover plate, and the fan is detachably assembled to the outside of the cover plate via the flange ring.

[0011] The circulating medium inside the circulation pipe, connecting pipe, conveying pipe, and return pipe is cooling gas.

[0012] Each of the circulating pipes has several air holes on its inner wall to allow the internal cooling gas to be ejected outwards for heat dissipation.

[0013] Each of the circulating pipes has a detachable sealing plate installed on its inner side wall; each sealing plate has a number of mushroom nails fixed on one side, which can be fitted and sealed in the corresponding air hole to achieve air hole sealing when liquid medium is introduced into the pipeline.

[0014] Beneficial effects: This technical solution presents an outdoor distributed heat absorption unit dual-mode wearable human body cooling device. The same piping system can switch between two cooling modes: brine water cooling and micro-hole air jet cooling, adapting to different outdoor conditions. Water cooling provides long-lasting heat absorption, suitable for extended cooling, while air cooling is breathable and suitable for short-term cooling. It is equipped with a detachable sealing plate with mushroom-shaped studs. When ventilating, the sealing plate can be removed to allow air to be released through the vents. When water is supplied, the mushroom studs can be used to block the vents to prevent leakage. There is no need to replace the entire piping system, which greatly improves the versatility of the device and reduces the cost of parts replacement and use. Attached Figure Description

[0017] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0018] First embodiment, brine cooling mode Reference Figure 1 Figure 6 , Figure 8 This invention discloses an outdoor distributed heat absorption unit dual-mode wearable human body cooling device, which includes: considering the problems of traditional outdoor cooling clothing having messy pipe layout, uneven heat dissipation coverage, poor fit, and inability to adapt to users' bending over, large-scale limb movements, etc., a distributed vertical pipe splicing structure is designed. The cooling device includes several circulation pipes 2, several connecting strips 1, and several connecting pipes 3. The circulation pipes 2 are arranged vertically at equal intervals, and connecting strips 1 are fixed between adjacent circulation pipes 2. Connecting pipes 3 are installed between adjacent circulation pipes 2. A shell 4 is fixedly installed on the back side of the circulation pipes 2. A delivery pipe 10 and a return pipe 12 are respectively connected to the two sides of the shell 4. The delivery pipe 10 is connected to the uppermost circulation pipe 2, and the return pipe 12 is connected to the lowermost circulation pipe 2. A medium supply mechanism is installed inside the shell 4.

[0019] During operation, the medium supply mechanism delivers cooling brine to the entire pipeline system. The medium flows from top to bottom through the delivery pipe 10, filling all the circulation pipes 2 and connecting pipes 3, and fully covering the human torso through the distributed pipeline. This structure achieves full-area heat absorption and cooling through vertically equidistant distributed pipelines, while the connecting strap 1 ensures a close-fitting, flexible, and deformable fit, adapting to various outdoor limb movements, balancing wearing comfort with a uniform cooling effect throughout the body.

[0020] Reference Figure 6 Considering the lack of large-scale refrigeration equipment in outdoor environments and the problem of rapid temperature rise and cooling effect decay during the circulation of water-cooled medium, a semiconductor cooling plate 9 is added to the inner wall of the delivery pipe 10 and the return pipe 12. The semiconductor cooling plate 9 is fixedly attached to the inner wall of the delivery pipe 10 and the return pipe 12, and can perform real-time pre-cooling and cooling treatment on the brine medium flowing inside the pipeline.

[0021] During operation, before entering the trunk circulation pipe 2, the brine is cooled by passing through the semiconductor cooling plate 9 area in the delivery pipe 10 and return pipe 12, continuously maintaining the medium at a low temperature. This structure does not require external large-scale refrigeration equipment; it can achieve continuous cooling of the brine by relying on small semiconductor devices, effectively preventing temperature rise during medium transportation, significantly improving the efficiency of continuous water cooling outdoors, and making the equipment lightweight and more adaptable.

[0022] Reference Figure 7 Considering the installation of the micro water pump 11, a docking structure was designed for the connector 6 to work with the expansion joint pipe 7. Two connectors 6 are fixedly installed on the inner walls of both sides of the housing 4. The two connectors 6 are respectively connected to the delivery pipe 10 and the return pipe 12. The two expansion joint pipes 7 are respectively sealed and fitted on the outer walls of the corresponding connectors 6.

[0023] During operation, the telescopic joint pipe 7 can extend adaptively to fit the position of the micro water pump 11.

[0024] Reference Figure 6 Considering the cumbersome operation of adding, replacing, and draining brine in water-cooled mode, and the inconvenience of pipeline maintenance, a valve 18 is installed below the bottom circulation pipe 2. The entire set of circulation pipe 2, connecting pipe 3, delivery pipe 10, and return pipe 12 constitutes a closed brine circulation channel, and the bottom valve 18 is a controllable on / off structure.

[0025] During operation, brine filling, emptying, and replacement can be quickly completed through the bottom valve 18. Closing valve 18 ensures a closed-loop circulation in the pipeline. This structure simplifies the daily operation and maintenance of the water-cooled medium, making it convenient, time-saving, and labor-saving, effectively improving the convenience of daily use and maintenance of the equipment in water-cooled mode.

[0026] Reference Figure 6 , Figure 7Considering the problems of insufficient circulating power, poor brine flow, poor cooling uniformity, and inconvenience in disassembly and maintenance of existing water-cooled cooling equipment, a detachable micro water pump 11 media-driven structure is added. Flanges 8 are fixedly mounted on the outer wall of one end of each of the two expansion joint pipes 7, and the micro water pump 11 is detachably connected between the two expansion joint pipes 7 via two sets of flanges 8.

[0027] During operation, the miniature water pump 11 provides circulation power for the cooling brine inside the pipeline, driving the brine to continuously flow and exchange heat in a closed loop within the entire set of circulation pipe 2, connecting pipe 3, delivery pipe 10, and return pipe 12. This structure adopts a detachable assembly design with flange 8, allowing the miniature water pump 11 to be disassembled and replaced individually in case of failure, without the need to disassemble other components as a whole. This ensures smooth and stable brine circulation and improves the uniformity of water cooling across the entire human torso.

[0028] Reference Figure 4 Considering the problem that the air vents 13 are prone to leakage and have poor sealing performance during water circulation of the dual-mode equipment, making it impossible to achieve stable water-cooled operation, a detachable sealing plate 14 with mushroom nails 15 is designed to block the air vents. The sealing plate 14 is detachably installed on the inner wall of each circulation pipe 2, and several mushroom nails 15 are fixed on one side of the sealing plate 14. The mushroom nails 15 can accurately fit and block the corresponding air vents 13.

[0029] During water cooling operation, the sealing plate 14 is attached to the inside of the pipeline, and all vents 13 are sealed by the mushroom-shaped nails 15, forming a sealed cavity for the entire pipeline. This structure can completely seal the vents 13 in the pipeline, eliminating the problem of brine leakage and wetting of clothing in water cooling mode, and ensuring stable and reliable operation of water cooling mode.

[0030] Second embodiment: Micro-hole jet cooling mode Reference Figure 5 , Figure 8 Considering the problems of dust accumulation and blockage in traditional air-cooled outdoor cooling equipment, difficulty in maintenance and cleaning, poor stability of the fan 17, and high failure rate during long-term outdoor operation, a detachable fan 17 assembly structure is designed. In this embodiment, the media supply mechanism includes a cover plate 5, a flange ring 16, and a fan 17. The cover plate 5 is detachably sealed to the upper part of the housing 4, the flange ring 16 is embedded inside the cover plate 5, and the fan 17 is detachably assembled to the outside of the cover plate 5 via the flange ring 16.

[0031] During operation, after the fan 17 starts, it can continuously deliver cooling gas into the housing 4, providing a stable air source power for the entire air-cooled piping system. This structure facilitates quick disassembly of the fan 17 and opening of the housing 4, allowing for timely removal of outdoor dust and other debris that may cause blockages. It is easy to assemble and disassemble, dustproof and durable, effectively reducing the probability of failure in air-cooled mode and extending the service life of the equipment.

[0032] Reference Figure 2 , Figure 4 Considering that traditional air-cooled components have concentrated air outlets, large heat dissipation blind spots, poor air permeability and heat dissipation, and are prone to causing stuffiness and excessive sweating when exposed to high outdoor temperatures, several air holes 13 are evenly opened on the inner wall of the circulation pipe 2, so that cooling gas can flow through the entire set of circulation pipe 2, connecting pipe 3, delivery pipe 10, and return pipe 12.

[0033] When operating in air-cooled mode, the inner sealing plate 14 is removed, allowing all vents 13 to remain open. Cooling gas from inside the pipes can then be directly and evenly sprayed onto the body surface through the inner vents 13, accelerating air convection and rapid evaporation of sweat. This structure achieves distributed microporous airflow for comprehensive heat dissipation, eliminating heat loss zones and effectively reducing discomfort from stuffiness during outdoor activities. It also significantly enhances the breathability and cooling effect of the air-cooled mode.

[0034] Reference Figure 2 , Figure 4 Considering that the air-cooled mode does not require medium sealing and the structural switching is complicated, and traditional equipment cannot quickly adapt to the two working conditions of water and air, this embodiment relies on the detachable sealing plate 14 structure to achieve rapid mode switching.

[0035] During air-cooled operation, the sealing plate 14 with mushroom-shaped nails 15 can be directly removed, completely exposing the air vents 13 inside the circulation pipe 2 to ensure unobstructed airflow. This structure eliminates the need to replace the main pipeline; simply removing and installing the sealing plate 14 allows for quick switching to air-cooled operation. The mode switching is simple and efficient, significantly improving the equipment's adaptability and versatility across various scenarios, and reducing equipment usage and modification costs.

[0036] In summary, the improvement of this embodiment lies in: This invention allows for switching between two cooling modes—salt water cooling and micro-hole jet cooling—with a single piping system, adapting to different outdoor conditions. Water cooling provides sustained heat absorption, suitable for extended outdoor stays, while air cooling offers breathability, ideal for short periods of sweating during work. It is equipped with a removable sealing plate 14 with mushroom-shaped studs 15. When ventilating, the sealing plate 14 is removed to allow air to be released through the vents 13; when water is supplied, the mushroom-shaped studs 15 plug the vents 13 to prevent leaks. This eliminates the need to replace the entire piping system, significantly improving equipment versatility and reducing replacement and usage costs.

[0037] Working principle: This equipment is based on the distributed pipeline heat exchange principle. It relies on the same pipeline system to realize flexible switching between two cooling modes: brine cooling and micro-hole jet cooling, adapting to different outdoor scenarios.

[0038] The main body of the equipment consists of multiple sets of vertically equidistant circulation pipes 2, connecting belts 1 and connecting pipes 3 forming a fully covered pipeline structure. Combined with the medium supply mechanism inside the shell 4, it realizes medium circulation and heat exchange. At the same time, the semiconductor cooling plate 9 on the inner wall of the delivery pipe 10 and return pipe 12 pre-cools and cools the circulating medium in real time to ensure stable cooling effect.

[0039] When performing water cooling operations, staff use mushroom nails 15 to seal the air holes 13 inside the circulation pipe 2, and use the bottom valve 18 to seal the entire pipeline. Powered by the detachable miniature water pump 11, the cooling brine is driven to circulate in a closed loop within the pipeline. The brine's high heat absorption properties continuously absorb heat from the human body surface, achieving long-lasting constant temperature cooling, suitable for outdoor personnel to stay or work for extended periods.

[0040] When performing air-cooling operations, the sealing plate 14 with mushroom-shaped studs 15 is removed to fully expose the vents 13. Cooling gas is then delivered through the detachable fan 17 on the top of the housing 4. The cool air is evenly sprayed onto the human body surface through the vents 13 via the pipes, accelerating air convection and sweat evaporation, quickly relieving the stuffy and sticky feeling on the skin. This is suitable for short-duration, high-intensity work scenarios where sweating is common. This equipment can switch between dual modes simply by removing and installing the sealing plate 14, without replacing the main pipework, thus balancing equipment versatility, wearing comfort, and practicality for outdoor stays or work.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
