Description

Technical Field

[0001] The invention relates to the technical field of cooling clothing, and in particular to a method for preparing a cooling vest with a fabric structure and the cooling vest. Background Art

[0002] The cooling vest is a wearable garment that uses active cooling. It is based on semiconductor cooling technology and uses the Peltier effect between the P and N semiconductor material layers. When the current passes through the cooling module, heat transfer occurs between the two ends, resulting in a temperature difference to form a hot and cold end, so that the cold end (the end that fits the human body) achieves a cooling effect, and then the heat dissipation module dissipates the heat at the hot end (the end away from the human body), ultimately achieving effective human body cooling. That is, it mainly uses the characteristics of heat transfer between the two ends when the cooling module is powered on to generate a temperature difference to form a hot and cold end, thereby achieving a cooling and heat dissipation effect.

[0003] In existing cooling vests, a hard board substrate is usually used as a support, and the cooling module and the heat dissipation module are respectively located on both sides of the hard board substrate. Among them, the active cooling device is currently mainly assembled with a semiconductor layer on the hard board substrate. The cooling unit is a heavy hard block structure with a limited bending radius, which is not in line with human wearing habits. In addition, the cooling effect is uneven, and it is cumbersome and uncomfortable for human body to wear, making it difficult to be widely used in outdoor construction and maintenance operations. Therefore, there is an urgent need for a preparation method of a new wearable cooling vest to overcome the above defects. Summary of the invention

[0040] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0042] Refer to the following Figure 1 and Figure 2 A method for preparing a fabric structure cooling vest according to some embodiments of the present invention will be described.

[0043] Some embodiments of the present application provide a method for preparing a cooling vest with a fabric structure.

[0044] The first embodiment of the present invention proposes a method for preparing a fabric structure cooling vest, wherein the cooling vest mainly includes a cooling module and a heat dissipation module, wherein the cooling module includes a plurality of cooling units 5 for cooling, and the heat dissipation module includes a plurality of heat dissipation units 4 for heat dissipation; it can be understood that the cooling module and the heat dissipation module in the present disclosure still use the cooling principle and heat dissipation principle of traditional cooling clothes, and the present disclosure will no longer repeat its specific cooling-related structure and cooling part circuit. The focus of the present disclosure is to improve the manufacturing method and manufacturing process of the cooling vest based on the same cooling principle, which also involves restrictions on the form of the cooling unit 5 and the heat dissipation unit 4.

[0045] Specifically, Figure 1 As shown, the preparation method mainly includes the following steps S1 to S3.

[0046] S1. Weaving the refrigeration module, wherein a plurality of refrigeration units 5 are woven into a flexible fabric by weaving or embroidering to form a fabric-based flexible refrigeration sheet.

[0047] S2, weaving the heat dissipation module, wherein a plurality of heat dissipation units 4 are woven into a flexible fabric in a weaving manner to form a fabric-based flexible heat dissipation patch.

[0048] S3. The fabric-structured flexible heat dissipation patch and the fabric-structured flexible cooling sheet are combined by embroidery and / or sewing to form a fabric-structured cooling vest.

[0049] The flexible fabric includes a braided yarn, and the braided yarn is made of natural fiber or chemical fiber or a blended fabric of natural fiber and chemical fiber. Specifically, natural fibers include cotton, linen, silk, wool, etc.; chemical fibers include polyester, nylon, etc. Considering the application scenarios, comfort and economy of the cooling clothing, the braided yarn is preferably cotton yarn. In this disclosure, cotton yarn is used as an example for explanation.

[0050] Through the above preparation method, the dispersed refrigeration units 5 are formed into fabrics under the action of the braided wire, and the heat dissipation unit 4 is directly woven into the fabric. In this way, the coordination of the refrigeration module and the heat dissipation module does not need to rely on a hard board base, and the two fabrics can be combined by embroidery or sewing to form a garment. At the same time, due to the use of the weaving method, the garment can be more closely fitted and more convenient to wear.

[0051] It should be noted that the order of the above step S1 and step S2 is not fixed and can be adjusted as needed, and the two can also be performed simultaneously.

[0052] In some embodiments, the step S1 of weaving the refrigeration module comprises:

[0053] The first braided wire 1 is bonded to the refrigeration unit 5; for example, glue is used to fix the first braided wire 1 to the refrigeration surface of the refrigeration unit 5. Several refrigeration units 5 are arranged in an array to ensure the uniformity of refrigeration. The same first braided wire 1 can be bonded to multiple refrigeration units 5. Similarly, multiple first braided wires 1 can be bonded to one refrigeration unit 5.

[0054] The second braiding wire 2 is fixed as a warp on the heald frame of the braiding machine. At the shed, the warp is alternately distributed up and down, and a plurality of second braiding wires 2 are sequentially distributed up and down through the heald frame.

[0055] In the area where the warp threads are alternately distributed up and down, the first braided thread 1 bonded to the refrigeration unit 5 is placed in the middle position as the weft thread and introduced into the shed; the braided thread and the refrigeration unit 5 in the shed are distributed as shown in FIG. Figure 2 As shown, it can be understood that there is a certain angle between the warp and the weft, which varies according to the different weaving patterns, and usually a 90-degree angle can be selected.

[0056] The shed is closed by the heald frame, so that the warp and weft threads are interwoven to form a woven flexible cooling sheet.

[0057] In this embodiment, the heald frame and shed are common structures of a weaving machine, and their specific structures and usages are well known to those skilled in the art. This is only an explanation of the weaving process and will not be repeated here.

[0058] It is understandable that the fabric flexible refrigeration sheet does not necessarily have to have the braided wires completely cover the refrigeration units 5 , and necessary space for assembling and wiring several refrigeration units 5 may also be reserved.

[0059] In some embodiments, the shape of the refrigeration unit 5 includes at least one of a block, a strip, a sheet, and a fiber. The shapes of the multiple refrigeration units 5 can be the same or different, and should fit the corresponding parts of the human body as much as possible. In this disclosure, the sheet-shaped refrigeration unit 5 is mainly used as an example for description.

[0060] Specifically, the area of ​​a single sheet-shaped refrigeration unit 5 should not be too large, and the value range is 10-100mm 2 Meanwhile, the cooling capacity of a single refrigeration unit 5 can be between 1-100 mW as required.

[0061] In some embodiments, the heat dissipation unit 4 includes at least one of a filamentary metal heat dissipation unit 4 and a tubular water-cooling heat dissipation unit 4. Whether it is a filamentary metal heat dissipation unit 4 or a tubular water-cooling heat dissipation unit 4, both should be selected based on the ability to achieve weaving. Either one heat dissipation unit 4 can be selected alone, or both heat dissipation units 4 can be used in combination.

[0062] In some embodiments, the step of weaving the heat dissipation module comprises:

[0063] The filamentary metal heat sink unit 4 or the tubular water-cooled heat sink unit 4 is fixed as a warp on the heald frame of the braiding machine. At the shed, the warps are alternately distributed up and down, and a plurality of warps are sequentially distributed up and down through the heald frame.

[0064] In the area where the warp threads are alternately distributed up and down, the third weaving thread 3 is used as the weft thread and introduced into the shed;

[0065] The shed is closed by the heald frame, so that the warp and weft threads are interwoven to form a woven flexible heat dissipation patch.

[0066] Specifically, the metal heat dissipation unit 4 can be made of any metal material selected from copper, silver, aluminum, tungsten and platinum; the above metal materials, in a filamentary structure, still have good flexibility and are easy to weave. It is understandable that the metal heat dissipation unit 4 can be in a mesh, block, tube, etc. in addition to the filamentary form, and the filamentary form is the best.

[0067] The water cooling unit 4 uses any one of a silicone tube, a latex tube, a PVC tube, a rubber tube, and a polytetrafluoroethylene tube to carry the water cooling liquid, wherein the diameter of the tubular structure is 1-10 mm.

[0068] It is understandable that, in order to meet ergonomics, the bending radius of the fabric-based flexible heat dissipation patch formed by weaving is 5mm-10cm. Specifically, the bending radius of the fabric-based flexible heat dissipation patch at the corresponding position can be determined according to different body parts. For example, the bending radius of the relatively flat chest and back can be smaller, while the bending radius of the shoulder joint and elbow joint with relatively large curvature should be larger.

[0069] In any of the above embodiments, the weaving patterns of the fabric flexible cooling sheet and the fabric flexible heat dissipation patch are one of plain weave, twill, satin, jacquard, and knitted, which can be selected according to needs.

[0070] A specific embodiment of the present invention provides a method for preparing a cooling vest using copper wire as a metal heat dissipation unit 4, comprising the following steps:

[0071] 1) A cotton thread with a diameter of 0.3 mm was fixed to both sides of the refrigeration surface of a refrigeration unit 5 with an area of ​​4 cm×4 cm using AB glue, and then allowed to dry naturally.

[0072] 2) The cotton threads are fixed as warp threads on the heald frame of the weaving machine, and the distance between the cotton threads is about 1 cm. At the shed, the warp threads are alternately arranged one up and one down, and the heald frame is used to achieve the sequential up and down distribution. In the process of alternating up and down distribution of the warp threads, the cotton threads at both ends of the refrigeration unit 5 are placed in the middle part as weft threads, and the shed is closed by the heald frame after being introduced into the shed. The above operation is repeated to interweave the warp threads and the weft threads, and a fabric-based flexible refrigeration sheet can be obtained.

[0073] 3) The copper wire is fixed as the warp on the heald frame of the weaving machine, and the distance between the copper wires is 1 cm. At the shed, the warp is alternately distributed up and down, and the heald frame is used to achieve the up and down distribution in sequence. In the process of alternating up and down distribution of the warp, the cotton thread is used as the weft, and after being introduced into the shed, the shed is closed by the heald frame. The above operation is repeated to interweave the warp and weft, and a fabric-based flexible heat dissipation patch with a metal mesh structure can be obtained.

[0074] 4) The fabric flexible cooling sheet and the fabric flexible heat dissipation patch are combined by sewing technology.

[0075] 5) A certain voltage is applied to the cooling vest, and it is measured that the cooling temperature of the fabric per unit area is about 7°C when the voltage is about 3.5V, which can achieve the effect of cooling the human body. It is understandable that the above voltage application process should be insulated from the human body, for example, adding an insulating lining at the skin-contacting position, or wrapping the entire cooling vest with a thermally conductive insulating layer will not affect the cooling effect, but can also play an insulating and protective role.

[0076] Another specific embodiment of the present invention provides a method for preparing a cooling vest using a silicone tube as a water-cooling heat dissipation unit 4, comprising the following steps:

[0077] 1) A cotton thread with a diameter of 0.3 mm was fixed to both sides of the refrigeration surface of a refrigeration unit 5 with an area of ​​4 cm×4 cm using AB glue, and then allowed to dry naturally.

[0078] 2) The cotton threads are fixed as warp threads on the heald frame of the weaving machine, and the distance between the cotton threads is about 1 cm. At the shed, the warp threads are alternately arranged one up and one down, and the heald frame is used to achieve the sequential up and down distribution. In the process of alternating up and down distribution of the warp threads, the cotton threads at both ends of the refrigeration unit 5 are placed in the middle part as weft threads, and the shed is closed by the heald frame after being introduced into the shed. The above operation is repeated to interweave the warp threads and the weft threads, and a fabric-based flexible refrigeration sheet can be obtained.

[0079] 3) A silicone tube with a diameter of 1 mm is fixed as a warp on the heald frame of the braiding machine, and the distance between the silicone tubes is 1 cm. At the shed, the warp is alternately distributed up and down, and the heald frame is used to achieve the up and down distribution in sequence. In the process of alternating up and down distribution of the warp, cotton thread is used as the weft, and after being introduced into the shed, the shed is closed by the heald frame. The above operation is repeated to interweave the warp and weft, and a water-cooled tubular fabric flexible heat dissipation patch can be obtained.

[0080] 4) The fabric flexible cooling sheet and the fabric flexible heat dissipation patch are combined by sewing technology.

[0081] 5) A certain voltage was applied to the cooling vest. It was also measured that the cooling temperature per unit area of ​​the fabric was about 7°C when the voltage was about 3.5V, which can achieve the effect of cooling the human body.

[0082] Some other embodiments of the present invention provide a cooling vest with a fabric structure, which is manufactured using the preparation method provided in any of the above embodiments.

[0083] In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0084] Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
