Description

Technical Field

[0001] This invention relates to the field of high-temperature protective functional clothing technology, and in particular to a direct-cooling cooling garment. Background Technology

[0002] Cooling suits are core protective equipment that ensures the comfort and safety of workers in high-temperature environments. Currently, the mainstream technology approaches in the industry are divided into three types: air-cooled, water-cooled, and direct-cooled.

[0003] Air-cooled cooling clothing relies on fans to drive air convection and accelerate sweat evaporation. Although it is flexible to wear and highly versatile, its cooling effect is highly dependent on the ambient humidity. Under high humidity conditions, its heat dissipation efficiency is greatly reduced, and there are also issues with fan noise and vibration.

[0004] Water-cooled cooling suits transfer cooling energy through liquid circulation, providing uniform cooling that is unaffected by humidity. However, they have complex piping structures, a heavy overall load, and are prone to coolant leakage during prolonged use, posing safety hazards in electrical and precision equipment maintenance scenarios. Additionally, they have high maintenance costs.

[0005] Existing direct-cooling garments use semiconductor refrigeration technology, which avoids the risk of liquid leakage, but still have several technical defects: First, conventional cut-out heat dissipation fins have a large heat storage capacity, and after the module is powered off, residual heat can easily be conducted back to the cold end, causing a temperature rebound and a long restart cooling cycle; Second, metal cooling sheets are mostly fixed with glue, which is prone to delamination and failure under temperature fluctuations, resulting in insufficient reliability of the connection between the cooling module and the garment, and long-term wear can easily cause physical discomfort; Fourth, there is still room for improvement in the cooling stability and power consumption matching under high-temperature environments. Summary of the Invention

[0006] The purpose of this invention is to provide a direct-cooling cooling garment that addresses the technical problems of existing products, such as cold end reheating after power failure, easy failure of fixed structure, health hazards, and poor adaptability to different scenarios, thereby achieving multiple benefits including efficient cooling, safety and reliability, comfortable wear, and health protection.

[0007] To achieve the above objectives, the present invention provides a direct-cooling cooling garment, comprising a cooling vest body and at least one cooling drive unit. The cooling drive unit includes a shell and a metal sheet, a first phase change plate, a semiconductor cooling plate, heat dissipation fins, and a cooling fan, which are sequentially stacked inside the shell along the direction of heat conduction. The metal sheet is mechanically snapped and locked to the inner opening of the shell. The shell is fixed to the mounting position of the cooling vest body by magnetic snaps. The cooling vest body is equipped with a controller, which is electrically connected to each cooling drive unit.

[0008] Preferably, the heat dissipation fins have a sloping surface structure, with the surface of the heat dissipation fins being inclined, which increases the heat dissipation area while reducing the heat storage of the fins.

[0009] Preferably, the mechanical buckle is an integrally formed plastic inverted buckle structure on the inner wall of the outer shell, and the edge of the metal sheet is circumferentially fixed and clamped to the inner side of the outer shell.

[0010] Preferably, the magnetic buckle is pre-sewn and fixed to the mounting position of the cooling vest body, and the inner side of the outer shell is provided with a magnetic component and a buckle groove at the corresponding position. During installation, it is automatically positioned by magnetic attraction and locked by mechanical buckle.

[0011] Preferably, the magnetic buckle and the outer shell form a dual locking structure of magnetic positioning and mechanical buckling, enabling one-click quick assembly and disassembly.

[0012] Preferably, the cooling vest body has several mounting positions for cooling drive units, some of which are symmetrically installed in the lower chest area, and the other part is distributed in the back area.

[0013] Preferably, the cooling drive unit is centrally located in the non-core organ area below the chest and on the back, avoiding the chest cavity and abdominal cavity corresponding to the heart, lungs and other internal organs. The cooling vest body is provided with a cold insulation layer in the area corresponding to the core organs, forming double protection.

[0014] Preferably, the controller is positioned at the center of the chest area of ​​the cooling vest. The controller surface is equipped with a master switch, a power increase button, and a power decrease button. The master switch is used to control the start and stop of all cooling drive units, and the power increase and decrease buttons are used to achieve multi-level power adjustment.

[0015] Preferably, the cooling vest body is made of insulating, antistatic, wear-resistant, and tear-resistant fabric, with allowance for movement corresponding to the shoulder straps and side waist area.

[0016] Preferably, the shoulder straps and side waist area of ​​the cooling vest are provided with reflective strips.

[0017] Therefore, the present invention employs the above-mentioned direct-cooling garment, and the technical effects are as follows: (1) Upgraded heat dissipation performance, eliminating the risk of backheating after power failure. The broken surface heat dissipation fins replace the traditional cut-white structure. The sloping shape increases the heat dissipation area and improves the heat dissipation efficiency, while reducing the heat storage of the fins. This prevents residual heat from being conducted back to the cold end after power failure, and allows for rapid recovery of cooling after restarting.

[0018] (2) Double fixing structure, reliable and easy to disassemble and assemble. The metal cold plate adopts mechanical inverted locking to completely avoid the problem of delamination failure caused by temperature change; the cooling module and vest adopt magnetic attraction and inverted locking, which can be disassembled and assembled with one click, and the connection is firm and not easy to fall off.

[0019] (3) Safe and comfortable design, suitable for working scenarios. The insulating and anti-static fabric is suitable for high-risk scenarios such as power and metallurgy. Its wear-resistant and tear-resistant properties extend its service life. The ergonomic cut provides a comfortable feeling of restraint, and the reflective strips improve the safety of working in low-light environments.

[0020] (4) Precise zoned cooling with flexible and user-friendly control. Six modules precisely cover the core heat-generating areas of the human body, and multi-level power adjustment adapts to different work intensities and ambient temperatures, balancing cooling effect and battery life.

[0021] (5) Organ protection layout, taking into account both cooling and health. Actively avoid placing cold sources in the core organ area, and form a double protection with thickened cold insulation layer to avoid continuous low temperature stimulation of the internal organs and prevent physical discomfort caused by long-term low temperature operation.

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example 1 This invention provides a direct-cooling cooling garment, including a cooling vest body and at least one cooling drive unit. The cooling drive unit includes a shell 7 and a metal sheet 1, a first phase change plate 2, a semiconductor cooling plate 3, a heat dissipation fin 5, and a cooling fan 6, which are sequentially stacked inside the shell 7 along the direction of heat conduction. The metal sheet 1 is locked to the inner opening of the shell 7 by a mechanical buckle 8. The shell 7 is fixed to the mounting position 10 of the cooling vest body by a magnetic buckle 9. The cooling vest body is provided with a controller 11, which is electrically connected to each cooling drive unit.

[0028] like Figure 1 As shown, the cooling drive unit is the core of the present invention, and is assembled in layers along the direction of heat conduction and integrated inside the outer casing 7. The semiconductor cooling chip 3 is the core cooling component. In this embodiment, a 12703 type semiconductor cooling chip is used, along with an optimized drive circuit, which can maintain sufficient operating margin and continuously and stably output cooling capacity in high-temperature environments.

[0029] The cold end surface of the semiconductor cooling chip 3 is bonded to the first phase change plate 2, and the other side of the first phase change plate 2 is in close contact with the metal sheet 1; the hot end surface of the semiconductor cooling chip 3 is bonded to the second phase change plate 4, and the other side of the second phase change plate 4 is in close contact with the heat dissipation fins 5. The double-layer phase change plates can balance the heat exchange efficiency of the cold and hot ends, buffer temperature fluctuations, and avoid excessive local temperature differences from affecting the cooling stability.

[0030] The heat dissipation fins 5 feature a sloping surface design, unlike traditional flat, cut fins. The fin surface is inclined, effectively increasing the total heat dissipation area while reducing heat accumulation inside the fins. The cooling fan 6 is installed on the outside of the heat dissipation fins 5. During operation, it forces airflow through the gaps between the fins, quickly dissipating the heat generated at the hot end of the thermoelectric cooler 3 to the external environment. When the module is powered off, due to the low heat storage capacity of the sloping fins, residual heat is not significantly conducted back to the cold end, so the metal plate 1 does not experience significant temperature rebound. After power is restored, the cooling module can quickly return to normal cooling status without a long waiting period.

[0031] like Figure 2 As shown, the metal sheet 1 is fixed to the inner opening of the outer shell 7 by a mechanical buckle 8, with the cooling surface of the metal sheet 1 facing the human body surface. The mechanical buckle 8 is a plastic inverted buckle structure integrally formed on the inner wall of the outer shell 7. During assembly, the metal sheet 1 is horizontally inserted into the opening slot of the outer shell 7, and the inverted buckle structure automatically clamps the edge circumferential of the metal sheet 1, forming a stable mechanical lock.

[0032] This structure completely eliminates the traditional glue bonding method, fundamentally avoiding the risk of glue denaturation and delamination caused by long-term temperature changes of the metal sheet 1, thus greatly improving the product's service life and reliability. At the same time, the inverted assembly eliminates the need for glue application and curing processes, simplifying the production and assembly process and reducing manufacturing costs.

[0033] like Figure 3 As shown, the cooling module and the cooling vest body can be quickly assembled and disassembled via magnetic clips 9. The magnetic clips 9 are bases with magnetic attraction function, which are pre-sewn and fixed to the mounting position 10 of the cooling vest body.

[0034] The inner side of the outer casing 7 is equipped with magnetic attachments and inverted locking slots at corresponding positions. During installation, align the outer casing 7 with the magnetic snap-fit ​​9 and bring it close. The strong magnetic force automatically completes the positioning and adsorption, while the mechanical snap-fit ​​on the outer casing 7 engages with the slot of the magnetic snap-fit ​​9, forming a dual fixing structure of magnetic positioning and mechanical locking. This ensures connection strength, prevents the cooling module from accidentally falling off during operation or movement, and also enables one-click quick assembly. Disassembly only requires applying a reverse pulling force to separate the modules, making the operation convenient and allowing for easy cleaning of clothing or separate storage after disassembly.

[0035] like Figure 4 , Figure 5 As shown, the cooling vest body serves as the wearable carrier. In this embodiment, a total of six cooling drive units are deployed (this number is not limited; other numbers are still suitable), with two sets symmetrically distributed below the chest and four sets distributed in the back area. The cooling vest body is made of insulating, anti-static, wear-resistant, and tear-resistant fabric, possessing excellent electrical safety performance and mechanical durability, making it suitable for high-risk and high-temperature scenarios such as power maintenance and metallurgical operations.

[0036] The vest is ergonomically designed with ample room for movement in the shoulder straps and side waist areas, ensuring a comfortable and unrestricted fit suitable for extended work hours. Reflective strips are added to key areas such as the shoulder straps and side seams to improve visibility in low-light conditions, tunnels, and workshops, enhancing worker safety. All cooling modules employ an organ-protection layout: actively avoiding areas within the chest and abdominal cavities corresponding to vital organs such as the heart, lungs, spleen, and stomach, concentrating the cooling source on the muscles and surface heat dissipation areas of the lower chest and back, preventing direct and continuous stimulation of internal organs by low temperatures. Simultaneously, the areas of the vest corresponding to vital organs have a thickened insulation layer, forming a dual protection system of layout avoidance and fabric insulation, preventing drastic temperature fluctuations in these areas and making it suitable for prolonged, continuous high-temperature work.

[0037] like Figure 4 As shown, the controller 11 is positioned in the center of the chest area of ​​the cooling vest, allowing for easy one-handed operation. The controller 11 panel features three independent buttons: a master power button, a power increase button, and a power decrease button. These buttons are clearly labeled and arranged in distinct zones. All three buttons are directly connected to the internal main control unit, ensuring low command transmission latency and reliable operation. The master power button controls the power supply to all six cooling modules with a single touch, enabling rapid start-up and shutdown of the entire unit. The power increase and power decrease buttons are used to adjust the cooling output power in stages, achieving multi-level linear temperature control. Users can flexibly adjust the cooling level according to ambient temperature and workload, ensuring comfort while controlling power consumption and extending battery life.

[0038] Working principle: When this invention is in operation, pressing the main switch of the controller 11 powers on the semiconductor cooling chip 3, creating a temperature difference between the hot and cold ends based on the Peltier effect. The cold energy generated at the cold end is uniformly conducted to the metal plate 1 via the first phase change plate 2. The metal plate 1 is directly attached to the human body surface, carrying away heat from the body surface through solid-state heat conduction, thus achieving direct cooling without a medium.

[0039] Meanwhile, the heat generated at the hot end of the semiconductor cooling chip 3 is conducted to the surface-type heat dissipation fins 5 via the second phase change plate 4. The cooling fan 6 forces air to flow through the fins, quickly dissipating the heat to the external environment, maintaining a stable hot end temperature, and ensuring the continuous and efficient operation of the cooling cycle.

[0040] The cooling intensity can be adjusted via the power button during wear to suit different working conditions; when it needs to be washed or stored, the cooling module can be quickly removed from the cooling vest, making it flexible and convenient to use.

[0041] Therefore, the present invention adopts the above-mentioned direct cooling clothing to solve the technical problems of existing products such as cold end reheating after power failure, easy failure of fixed structure, health hazards, and poor adaptability to different scenarios, and achieves multiple effects such as efficient cooling, safety and reliability, comfortable wear, and health protection.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
