Description

[0001] This application claims priority to Chinese patent application filed on February 10, 2025, with application number CN202510144628.7, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of human body microenvironment temperature regulation technology, and in particular to a liquid circulation human body heat exchange device with a segmented structure. Background Technology

[0003] Many workers in various industries need to work in extreme outdoor temperatures. Prolonged exposure to high or low temperatures not only affects work efficiency but also harms health. To protect workers' health and improve work efficiency, it is necessary to equip those working in extreme outdoor environments with devices that regulate body temperature. Currently, a relatively effective method is for workers to wear specially designed clothing with evenly distributed liquid circulation channels. These channels are flexible, and the lining of the clothing is in full contact with the body's outer surface. In high-temperature working environments, cooled, low-temperature liquid flows through the channels, exchanging heat with the body's surface, lowering body temperature and improving comfort. The liquid flowing out after heat exchange is cooled and then pumped back into the channels, continuously circulating. In low-temperature working environments, heated, high-temperature liquid flows into the channels. The circulation process for the high-temperature liquid is similar to that for the low-temperature liquid and will not be elaborated further. In other words, this heat-exchange clothing can be used for both heating and cooling in low-temperature and high-temperature environments, but its application is more prevalent in high-temperature environments.

[0004] Many types of hose materials can be used in heat exchange clothing, including silicone hoses and plastic hoses, with flexible PVC (polyvinyl chloride) hoses being the most common. Currently, there are three methods for attaching the hoses to the base garment fabric. The first and most common method uses a custom-made sewing machine presser foot to sew the hoses to the fabric using a serrated stitch. The second method is used in astronaut heat exchange suits, where a mesh material is used to create the base garment, and the hoses are "woven" into the fabric. The third method is lamination, where the hoses are arranged in a desired pattern between two layers of fabric, adhesive is applied between the layers, and then they are pressed together in a flatbed press. After pressing, the hoses are fixed between the two layers of fabric. The pressure and temperature parameters used in the press depend on the type of adhesive used. Considering versatility and cost, the first method is the most widely used, followed by the third method.

[0005] In heat exchange garments, a single-loop structure with a single flexible pipe running from beginning to end is rarely used. This structure has several drawbacks, such as excessively long pipes and significant temperature differences between the beginning and end, affecting temperature uniformity within the garment. A multi-loop structure with multiple parallel fluid paths is more commonly used. Circulating liquid from the cold / heat source flows into the input end of the heat exchange garment, where a distributor distributes the liquid from the main pipe to multiple connected parallel loops. After heat exchange within the garment, the circulating liquid passes through a collector, concentrating the liquid flowing from each parallel loop into the output main pipe, which is connected to the cold / heat source. In existing technologies, each circulation loop in a heat exchange garment is a single, seamless flexible pipe.

[0006] For the first method of securing the tubing hose described above, crossing the seam between the front and back of the garment, such as the shoulder seam, requires two steps. The first step is to sew the basic garment fabric; the second step is to use a serrated needle to secure the tubing hose to the pre-made fabric according to the predetermined hose arrangement pattern. This method is extremely inefficient. Furthermore, during the sewing process, the needle can easily puncture the hose. Once punctured, the garment must be discarded, increasing production costs.

[0007] For the third method of fixing the tubing and hoses mentioned above, the lamination during pressing can only be done on a single plane. It is impossible to first make the garment into a basic fabric and then add the tubing and hoses for pressing. Each tubing and hose loop can only be arranged within a continuous plane on the front or back, and cannot cross the seam between two planes, such as the shoulder. Therefore, it is difficult to create heat exchange garments with complex circulation loops using lamination.

[0008] Using lamination to fix pipes and hoses requires the creation of specific templates. The layout of the grooves on the templates must perfectly match the loop layout of the liquid circulation pipes and hoses on the heat exchange garment. In other words, using lamination to fix pipes and hoses incurs the cost of template creation. The advantage is that using templates improves production efficiency, allows for very small bending radii of the pipes and hoses, and enables very small spacing between adjacent pipes. This means that pipes and hoses can be arranged in a high-density layout on the heat exchange garment.

[0009] Compared to lamination, the zigzag stitch method has the advantage of eliminating template manufacturing costs. However, it suffers from lower production efficiency. Limited by the sewing machine head's turning radius, it's difficult to achieve a very small curvature radius for the tubing and hoses, making high-density placement of the tubing and hoses challenging in heat exchange garments. A second drawback of the zigzag stitch method is the pinhole problem. Pinholes will appear wherever the tubing and hoses are sewn into the base lining. In the manufacture of chemical protective clothing, harmful substances could come into contact with the skin through these pinholes, which is absolutely unacceptable. In other words, the zigzag stitch method cannot be used in the production of heat exchange garments where pinholes are strictly prohibited. A third drawback is that the thread used to secure the tubing and hoses comes into contact with the skin, which can cause skin irritation and discomfort.

[0010] Because the lamination process allows the layers to be laid on a single plane, the tubing and hose loops can only circulate within a single plane on the front or back, and cannot cross between two planes. Therefore, the distributor / manufacturer must be installed under one armpit to accommodate both the front and back circulation loops. The entire front panel must be a single, continuous piece; a zipper cannot be installed in the middle, otherwise the circulation pipes on the left and right sides of the front panel would not be able to connect.

[0011] In summary, based on current technology, constructing liquid-circulating heat exchange garments using lamination methods also has several drawbacks. Firstly, the liquid circulation hoses within the garment can only circulate within a single planar area, not across different areas. Secondly, the garment cannot have a front opening or zipper, making it inconvenient for the user to put on and take off. Thirdly, the distributor / collector can only be installed under one armpit, resulting in significant asymmetry between the left and right sides of the garment, affecting both aesthetics and wearer comfort. Therefore, it is currently difficult to manufacture complex, high-performance heat exchange garments using lamination methods.

[0012] During the manufacturing and use of heat exchange garments, the flexible circulation tubing is easily punctured by sharp objects. Repairing damaged tubing is currently a challenge. This is mainly because the tubing is very thin, with a small radius of curvature on its outer surface, making it difficult to apply a rubber patch. Even if it is successfully applied, the small contact area makes it prone to detaching during use. Utility Model Content

[0013] To address the shortcomings of existing technologies, this invention provides a modular liquid-circulating human body heat exchange device. Ideal liquid-circulating human body heat exchange garments should possess characteristics such as softness, breathability, body fit, absence of pinholes, and high heat exchange rate, while also being easy to put on and take off without restricting the wearer's freedom of movement. A good solution is to employ a laminated liquid-circulating human body heat exchange garment with a high-density layout of liquid circulation pipes and hoses. The garment has an opening at the chest, allowing the distributors and collectors to be installed in any desired location on the heat exchange garment, not just under the armpits. Achieving this functionality requires overcoming the problems and deficiencies in the manufacturing process of laminated liquid-circulating human body heat exchange garments. The basic idea of ​​this utility model is as follows: First, the liquid circulation pipe hose loop is designed and laid out across the garment pieces; then, the heat exchange garment body with the layout pattern across the pieces is decomposed into basic garment pieces, and the liquid circulation pipe hose loop is fixed on each basic garment piece according to the pipe hose layout pattern using a lamination method; then, all the basic garment pieces with the fixed liquid circulation pipe hose loop are sewn together to form a complete garment; at the same time, the liquid circulation pipe hose loops located on different basic garment pieces are connected and connected to form a complete liquid circulation pipe hose loop across the basic garment pieces.

[0014] While the serrated needle method can be used to attach the tubing to the pre-made base fabric across the seams between garment pieces, it is extremely inefficient, and the needle can easily puncture the tubing during sewing. The solution is to break down the heat exchange garment into basic garment pieces, and use the serrated needle method to attach the liquid circulation tubing loop to each basic garment piece. Then, all the basic garment pieces with attached liquid circulation tubing loops are sewn together to form a complete garment. Simultaneously, the liquid circulation tubing loops on different basic garment pieces are connected to form a complete liquid circulation tubing loop spanning all the basic garment pieces.

[0015] Therefore, for the manufacture of liquid-circulating heat exchange garments, regardless of whether lamination or serrated stitching is used, the most effective method is to disassemble the heat exchange garment into pieces, fix a liquid circulation pipe hose loop on each piece, and then connect all the pieces together. A crucial step in this process is connecting the pipe hoses located on different garment pieces to form a complete liquid circulation pipe hose loop spanning the pieces; this involves a pipe hose connection device.

[0016] The main problems that this utility model needs to solve include the following aspects:

[0017] 1. The technical limitations of existing laminated heat exchange garment construction include: the liquid circulation pipe hose can only circulate within a single plane (such as the front or back) and cannot be connected across areas (such as the front and back), resulting in limited space design for the pipe loop; the front must be a one-piece structure, which cannot be opened or fitted with a zipper, affecting the user's wearing and taking off experience and causing inconvenience; the distributor and collector can only be installed under one armpit, resulting in asymmetry of the garment, affecting aesthetics and wearing comfort.

[0018] 2. The technical drawbacks of the existing serrated needle method for fixing pipes include: the pipes need to be fixed a second time on the already sewn basic garment, which is a complicated process and easy to puncture the hose, resulting in a high scrap rate, increased costs, and low production efficiency; the needle holes produced by sewing may allow harmful substances to seep in (such as in chemical protective clothing scenarios), and the direct contact of the sewing thread with the skin can easily cause discomfort, which may cause functional and safety hazards; the pipe layout design is limited by the rotation radius of the sewing machine head, that is, the pipe bending radius is large, making it difficult to achieve a high-density layout, which affects the heat exchange efficiency.

[0019] 3. Challenges in repairing damaged tubing: When the flexible tubing in heat exchange garments is damaged, traditional patching methods easily detach due to the small curvature of the outer surface and limited contact area, making repair difficult. Therefore, existing technologies, whether lamination or serrated needle method, lack reliable tubing connection devices, making it impossible to efficiently connect tubing loops between different garment pieces, thus limiting the design of complex three-dimensional loops and the flexibility of garment structures.

[0020] This utility model aims to solve the core problems mentioned above, such as cross-regional circulation, ease of donning and doffing, structural symmetry, production efficiency, and pipe connection, by using a modular construction and a method of independently fixing the pipes in sections and then stitching them together. This fills the technical gap in cross-section pipe connection for liquid circulation human body heat exchange equipment.

[0021] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a modular liquid circulation human body heat exchange device, comprising: a garment body, a liquid circulation pipe hose loop, a distributor and a collector, and input and output main pipe hoses; the liquid circulation pipe hose loop adopts a multi-loop structure with multiple parallel fluid paths; the distributor and collector are provided with one main port and multiple sub-ports, the end of the liquid circulation pipe hose loop is connected to the sub-port of the distributor and collector, and the input and output main pipe hoses are connected to the main port of the distributor and collector; the garment body includes multiple independent garment base pieces, and the liquid circulation pipe hose loop is arranged on each garment base piece according to a preset path, wherein part of the preset path extends to the edge area of ​​each garment base piece; the liquid circulation pipe hose loop is fixed to the two layers of fabric of each garment base piece by lamination, or the liquid circulation pipe hose loop is fixed to each garment base piece by serrated needle method.

[0022] It also includes a pipe hose connection device, which is a tubular connector with a material compatible with the pipe hose to be connected. Its inner diameter is adapted to the outer diameter of the pipe hose to be connected to form a tight fit. The pipe hose connection device connects the ends of the liquid circulation pipe hose loops located at the edge area of ​​adjacent garment base pieces together, and the length of the end of the liquid circulation pipe hose loop extending out of the edge area is sufficient to form a liquid-tight joint through the pipe hose connection device, so that the liquid circulation pipe hose loop forms a complete circulation loop across the garment base pieces.

[0023] Furthermore, the basic garment pieces of the main garment body include a left front area piece, a right front area piece, and a back area piece, with the left front area piece and the right front area piece forming a front opening structure.

[0024] The liquid circulation pipe hose loops on the left and right front sections are connected to the liquid circulation pipe hose loops on the back section through the pipe hose connection device to form a complete cross-section circulation loop.

[0025] The front opening structure is equipped with a closing device, which includes a zipper, a button, or a Velcro strap.

[0026] Furthermore, the diverter and collector can be installed on the left front panel, right front panel, back panel of the garment body or in the armpit area; the sub-ports of the diverter and collector are respectively connected to the ends of the liquid circulation pipe hose loops on the left front panel, right front panel and back panel.

[0027] Furthermore, the pipe hose connection device is a flexible sleeve or a rigid sleeve. The ends of the two pipe hoses to be connected are respectively inserted into the two end cavities of the sleeve. The inner wall of the sleeve and the outer wall of the pipe are formed into a liquid-tight joint by solvent bonding, ultrasonic welding or radio frequency welding. The fluid cross-sectional area of ​​the connection of the pipe hose connection device is the same as the fluid cross-sectional area of ​​the pipe hoses to be connected.

[0028] Furthermore, when the end faces of the two pipes and hoses to be connected axially abut against each other, the sleeve wraps around and presses the outer circumferential surface of the abutting part; when there is an axial gap between the end faces of the two pipes and hoses to be connected, the sleeve simultaneously covers the outer circumferential surface of the two separate end faces, and a liquid-tight joint is formed by the interference fit between the inner wall of the sleeve and the outer wall of the pipes and hoses to be connected.

[0029] Furthermore, the main body of the garment also includes sleeves, and the end of the liquid circulation pipe hose loop on the sleeve is connected to the end of the liquid circulation pipe hose loop on the garment base piece through a pipe hose connection device to form a complete circulation loop.

[0030] Furthermore, it also includes a repair structure, which is the pipe hose connection device used for repairing and connecting damaged parts of the pipe hose.

[0031] By employing the above technical solution, this utility model provides a modular liquid circulation human body heat exchange device and its preparation method, which has at least the following beneficial effects:

[0032] 1. By breaking down heat exchange garments into pieces and producing multiple pieces in parallel, production efficiency and quality are improved.

[0033] 2. The liquid circulation pipe hose loop can circulate across the plates within the heat exchange garment, making the layout of the liquid circulation pipe hose loop more flexible and enabling the production of heat exchange garments with high-performance structures.

[0034] 3. By rationally arranging the liquid circulation pipe hose loops, even using the lamination method, the open-front design of the heat exchange garment can be achieved, making it more convenient to put on and take off the heat exchange garment.

[0035] 4. Through the reasonable layout of the liquid circulation pipeline hose circuit, the distributor and collector can be installed in any desired location on the heat exchange garment, not limited to the underarm. This also makes the heat exchange garment symmetrical on both sides, which is not only beautiful but also more comfortable to wear.

[0036] 5. The pipe hose connector is very well integrated with the pipe hose. The outer diameter of the connection is adapted to the outer diameter of the pipe hose to form a liquid-tight connection. The flexibility of the connection is close to that of the pipe hose. There is no reduction in the cross-sectional area of ​​the fluid, and the flow rate of the liquid will not be affected.

[0037] In summary, this utility model aims to solve the core problems of cross-regional circulation, ease of donning and doffing, structural symmetry, production efficiency, and pipe connection by using a modular construction and a method of independently fixing the pipes in sections and then stitching them together. This fills the technical gap in cross-section pipe connection for liquid circulation human body heat exchange equipment. Attached Figure Description

Detailed Implementation

[0045] As used herein, "body heat exchange device" or "body heat exchange clothing" refers to wearable clothing items, including vests, jackets, sleeves, coats, shirts, suits, trousers, work clothes, headscarves, hats, boots, gloves, and any other type of complete or partial body covering, including blankets or tarpaulins. It can be configured to support tubing in close contact with the body to carry circulating fluid, thereby controlling body temperature through the cooling or heating of the circulating fluid.

[0046] As used herein, the terms “first,” “second,” “third,” and “fourth” are used to describe various parts, but these parts are not limited by these terms. These terms are used only to distinguish one part of the same class from several other parts and should not be construed as indicating or implying relative importance.

[0047] Please refer to Figures 1-5 This invention illustrates a specific implementation of the present embodiment. In this embodiment, a pipe and hose connecting device connects liquid circulation pipe and hose loops located on different garment base pieces into a complete circulation loop, allowing the liquid circulation pipe and hose loop to circulate across garment base pieces. This makes the layout of the liquid circulation pipe and hose loop more flexible, enabling the production of heat exchange garments with a three-dimensional, high-performance structure. Secondly, the pipe and hose connecting device and the pipe and hose are very well integrated; the outer diameter of the connection point matches the outer diameter of the pipe and hose to form a liquid-tight connection. The flexibility of the connection point is close to that of the pipe and hose, without reducing the fluid cross-sectional area and without affecting the liquid flow rate. Through the rational layout of the liquid circulation pipe and hose loop, an open-front design of the laminated liquid circulation human body heat exchange device can be achieved, and the distributor and collector can be installed in any desired location on the garment. The modular manufacturing of the liquid circulation human body heat exchange device improves production efficiency and quality. This invention also provides an effective repair structure for repairing damaged liquid circulation pipe and hose loops.

[0048] Please refer to Figure 1 and Figure 2 This embodiment proposes a modular liquid circulation human body heat exchange device, which includes a garment body 1, a liquid circulation pipe hose loop, a distributor and a collector, and input and output main pipe hoses. The liquid circulation pipe hose loop adopts a multi-loop structure with multiple parallel fluid paths. The distributor and collector are provided with one main port and multiple sub-ports. The end of the liquid circulation pipe hose loop is connected to the sub-port of the distributor and collector, and the input and output main pipe hoses are connected to the main port of the distributor and collector. The garment body 1 includes multiple independent garment base pieces. The liquid circulation pipe hose loop is arranged on each garment base piece according to a preset path, wherein part of the preset path extends to the edge area of ​​each garment base piece. The liquid circulation pipe hose loop is fixed to the two layers of fabric of each garment base piece by lamination or by serrated needle method.

[0049] It also includes a pipe hose connection device 5, which is a tubular connector with a material compatible with the pipe hose to be connected. Its inner diameter is adapted to the outer diameter of the pipe hose to be connected to form a tight fit. The pipe hose connection device 5 connects the ends of the liquid circulation pipe hose loops located in the edge area of ​​adjacent garment base pieces together, and the length of the end of the liquid circulation pipe hose loop extending out of the edge area is sufficient to form a liquid-tight joint through the pipe hose connection device 5, so that the liquid circulation pipe hose loop forms a complete circulation loop across the garment base pieces.

[0050] Specifically, the pipe hose connector 5 can be well integrated with the pipe hose to be connected. The outer diameter of the pipe hose connector 5 at the pipe hose connection point is adapted to the outer diameter of the pipe hose. The flexibility at the pipe hose connection point is close to that of the pipe hose. The fluid cross-sectional area at the pipe hose connection point is the same as that of the pipe hose. Figure 3 This is one embodiment of the present invention, comprising a pipe hose connecting device 5 and two pipe hoses to be connected, namely a first hose 25 and a second hose 26. The pipe hose connecting device 5 is a tubular connector with a material compatible with the pipe hoses to be connected, and its inner diameter is adapted to the outer diameter of the first hose 25 and the second hose 26 to form a tight fit. The pipe hose connecting device 5 sleeves the two hoses to be connected together.

[0051] Specifically, the material of the pipe hose connection device 5 should be compatible with the materials of the first hose 25 and the second hose 26. In one embodiment, the first hose 25 and the second hose 26 are made of PVC, and the pipe hose connection device 5 is also made of PVC. This allows for the formation of a reliable liquid-tight joint using known methods, including solvent bonding, ultrasonic welding, and radio frequency welding. Those skilled in the art can select conventional liquid-tight connection methods based on the hose material.

[0052] Specifically, when the end faces of two hoses to be connected axially abut against each other, the hose connection device 5 wraps around and presses against the outer circumferential surface of the abutment portion; in one embodiment, such as Figure 3As shown, the end faces of the two hoses 25 and 26 to be connected within the hose connection device 5 are in close contact. Inside the cavity of the hose connection device 5, the end faces of the first hose 25 and the second hose 26 are fitted together, allowing them to be tightly connected at their end faces. Simultaneously, the inner surface of the hose connection device 5 is tightly fitted with the outer surfaces of the first hose 25 and the second hose 26, ensuring a tight seal. Therefore, at the connection point of the hose connection device 5, there is a sufficiently large connection area, and the hose connection device 5 does not need to use a sleeve with excessively thick walls. While ensuring a certain connection strength, a sleeve with thin walls should be selected as much as possible so that the outer diameter of the sleeve at the connection point is close to the outer diameter of the hose. In one embodiment, the wall thickness of the sleeve is selected to be half the wall thickness of the hose, resulting in excellent feel and wearing experience. The hardness of the sleeve material is reasonably selected so that the softness at the connection point is close to that of the hose.

[0053] from Figure 3 It can be seen that when the liquid flows from the first hose 25 through the pipe hose connection device 5 to the second hose 26, there is no change in the fluid cross-sectional area at the connection point. Therefore, the introduction of the pipe hose connection device 5 does not introduce additional resistance and affect the flow rate of the liquid.

[0054] Therefore, it can be seen that the pipe hose connection device 5 of this utility model is compatible with the pipe hose to be connected in terms of both outer diameter and flexibility at the connection point. At the same time, there is no change in the cross-sectional area of ​​the fluid at the connection point, and the flow rate of the liquid is not affected, thus perfectly solving the connection problem of pipe hose.

[0055] Specifically, when there is an axial gap between the end faces of the two hoses to be connected, the hose connection device 5 simultaneously covers the outer circumferential surfaces of the two separated end faces, and a liquid-tight joint is formed by the interference fit between the inner wall of the sleeve and the outer wall of the hose to be connected; in another embodiment, such as Figure 5 As shown, the pipe hose connection device 5 connects the two pipe hoses with separate end faces together, thus serving as a bridging device.

[0056] Furthermore, such as Figure 5 As shown, the length of the pipe hose connection device 5 is L, the length of the interface between the pipe hose connection device 5 and the first hose 25 is L1, and the length of the interface between the pipe hose connection device 5 and the second hose 26 is L2. To ensure a reliable connection, the required length varies depending on the connection process used (adhesion, welding). These differences in length parameters should not deviate from the scope of protection of this utility model.

[0057] Furthermore, the inner diameter of the aforementioned pipe hose connecting device 5 is the same as the outer diameter of the pipe hose to be connected. However, there are errors in engineering practice, and it is difficult to achieve a strict match. As long as the inner diameter of the pipe hose connecting device 5 and the outer diameter of the pipe hose to be connected are adapted to form an interference fit and are tightly connected together, and the connecting technology of this utility model is used, they all fall within the protection scope of this utility model.

[0058] In one embodiment, the pipe hose connection device 5 is a flexible sleeve; the ends of the two pipe hoses to be connected are respectively inserted into the two end cavities of the sleeve, and the inner wall of the sleeve and the outer wall of the pipe are formed into a liquid-tight joint by solvent bonding, ultrasonic welding or radio frequency welding; the fluid cross-sectional area of ​​the connection of the pipe hose connection device 5 is the same as the fluid cross-sectional area of ​​the pipe hoses to be connected.

[0059] Specifically, the connection of the liquid circulation pipeline hose adopts the pipeline hose connection device 5 of this utility model. The advantages of this connection method are: the outer diameter of the connection is adapted to the outer diameter of the pipeline hose, the flexibility of the connection is close to that of the pipeline hose, and the fluid cross-sectional area of ​​the connection is the same as that of the pipeline hose, so as not to affect the flow speed of the liquid.

[0060] In another embodiment, the pipe hose connection device 5 is a rigid sleeve to obtain maximum support. Although a rigid pipe is used, the connection technology of this invention ensures that the fluid cross-sectional area at the connection point will not be reduced, thus not affecting the flow rate of the circulating liquid, which is also within the protection scope of this invention.

[0061] The existing technology for constructing liquid-circulating heat exchange clothing using lamination involves the following steps: First, a flatbed press is used to press tubing and hoses arranged in a predetermined loop pattern into the space between two layers of fabric. An adhesive is applied between the two layers, and the temperature and pressure parameters of the press depend on the type of adhesive material used. Second, the pressed fabric containing the circulating tubing and hoses is trimmed to the size and shape of the front or back. Third, Velcro straps are attached to the trimmed front and back pieces, one on each shoulder. The front and back pieces are joined together by shoulder straps, and Velcro straps under the armpits are used to adjust the chest size when worn.

[0062] Based on existing technology, the circulation tube loops fixed by lamination can only circulate within a single plane on the front or back, and cannot pass between two planes. Therefore, the distributor and collector must be installed under the armpit on one side of the garment to simultaneously accommodate circulation loops on both the front and back. The entire front must be a single, solid piece, without a zipper in the middle. Otherwise, the circulation tubes on the left and right sides of the front cannot be connected. Given current technology, it is difficult to create three-dimensional, high-performance heat exchange garments using lamination.

[0063] To address the problems encountered in the production of liquid-circulating human body heat exchange garments, this invention provides a modular liquid-circulating human body heat exchange device, the manufacturing principle of which includes the following steps:

[0064] (a) Design the structure of the main body of the garment 1, and decompose the main body of the garment 1 into multiple independent basic garment pieces; the front opening structure can be selectively designed between the left front piece 11 and the right front piece 12 of the upper garment.

[0065] (b) According to the heat exchange requirements, the liquid circulation pipe hose loops are arranged in a layout pattern on each garment base piece according to a preset path, wherein some of the preset paths extend to the edge area of ​​each garment base piece.

[0066] (c) Select a pipe hose connection device 5 that is compatible with the material of the pipe hose to be connected. The pipe hose connection device 5 is a flexible sleeve or a rigid sleeve, the inner diameter of which is adapted to the outer diameter of the pipe hose to be connected to form a tight fit.

[0067] (d) The liquid circulation pipe hose is fixed to each garment base piece by lamination, and the end of the liquid circulation pipe hose loop is reserved at the edge area;

[0068] (e) Trim the garment base piece with the liquid circulation pipe hose loop to the preset size and sew it into a complete garment;

[0069] (f) At the seam of adjacent garment base pieces, insert the end of the hose to be connected into the two end cavities of the hose connection device 5, and form a liquid-tight joint by solvent bonding, ultrasonic welding or radio frequency welding, so that the liquid circulation hose loop forms a complete circulation loop across the pieces.

[0070] (g) Add securing measures at pipe and hose connections: cover exposed pipes with adhesive lining material;

[0071] (h) For garments with an open front design, a closure device is installed at the opening of the garment, the closure device including a zipper, a button or a Velcro strap; a garment bust adjustment device is installed in the armpit area on both sides of the garment, the bust adjustment device including a buckle, an elastic band, elastic fabric or a Velcro strap;

[0072] (i) The end of the liquid circulation pipeline hose is connected to the corresponding sub-port of the distributor and the collector, and the input and output main pipeline hoses are connected to the main ports of the distributor and the collector.

[0073] Figure 1 and Figure 2 This is a schematic diagram of one embodiment of heat exchange garment. Figure 1 This is a front view. Figure 2This is a back view, showing a heat exchange vest. Heat exchange garments typically consist of an inner lining fabric, a middle layer of liquid circulation tubing, and an outer fabric layer. The outer fabric layer has been obscured to allow a clear view of the internal liquid circulation tubing structure.

[0074] The heat exchange vest includes: a garment body 1, four-way liquid circulation pipe hose circuits, two distributors and collectors, and two input and output main pipe hoses connected to a cooling / heating source.

The sub-ports of the distributor and collector are respectively connected to the ends of the liquid circulation pipe hose loops on the left front panel, right front panel, and back panel.

[0076] Figure 4This is an embodiment of a liquid-circulating human body heat exchange vest manufactured using the technology of this utility model. It achieves improved production efficiency through a three-block design. Furthermore, a front opening structure is formed between the left front block 11 and the right front block 12. The first distributor and collector 31 and the second distributor and collector 32 are installed on the lower right side of the back, making it convenient and comfortable to wear. The manufacturing principle of the liquid-circulating human body heat exchange vest is as follows:

[0077] (a) Design the structure of the main body of the garment 1, and decompose the main body of the garment 1 into three pieces: left front area piece 11, right front area piece 12 and back area piece 13; design a front opening structure between the left front area piece 11 and the right front area piece 12;

[0078] (b) According to the heat exchange requirements, the left front zone liquid circulation pipe hose loop 21, the right front zone liquid circulation pipe hose loop 22, the left back zone liquid circulation pipe hose loop 23 and the right back zone liquid circulation pipe hose loop 24 are arranged in a layout pattern on the left front zone block 11, the right front zone block 12 and the back zone block 13 according to a preset path, wherein some of the preset paths extend to the edge area of ​​each garment base block;

[0079] (c) Select a pipe hose connection device 5 that is compatible with the material of the pipe hose to be connected. The pipe hose connection device 5 is a flexible sleeve or a rigid sleeve, the inner diameter of which is adapted to the outer diameter of the pipe hose to be connected to form a tight fit.

[0080] (d) Fix the left front area liquid circulation pipe hose loop 21, right front area liquid circulation pipe hose loop 22, left back area liquid circulation pipe hose loop 23 and right back area liquid circulation pipe hose loop 24 to the three pieces of clothing respectively by lamination or sawtooth needle method, and leave a length at the end of the liquid circulation pipe hose loop in the edge area.

[0081] (e) Trim the three pieces with the liquid circulation pipe hose loop to the preset size, sew the left front area piece 11 with the circulation pipe hose installed and trimmed to the back area piece 13 together at the left shoulder, and sew the right front area piece 12 with the circulation pipe hose installed and trimmed to the back area piece 13 together at the right shoulder to form a complete garment.

[0082] (f) At the two shoulder seams of adjacent garment base pieces, insert the ends of the hoses to be connected into the two end cavities of the hose connection device 5, and form a liquid-tight joint by solvent bonding, ultrasonic welding or radio frequency welding, so that the left back liquid circulation hose loop 23 on the back piece 13 and the left front liquid circulation hose loop 21 on the left front piece 11 are connected across the shoulder by the first connection device 51 and the second connection device 52, and the right back liquid circulation hose loop 24 on the back piece 13 and the right front liquid circulation hose loop 22 on the right front piece 12 are connected across the shoulder by the third connection device 53 and the fourth connection device 54, and finally form a complete circulation loop; Figure 4 The first connecting device 51, the second connecting device 52, the third connecting device 53, and the fourth connecting device 54 are... Figure 3 or Figure 5 The length L of the pipe hose connection device 5 shown in the diagram is adjusted according to the connection process.

[0083] (g) Install a closure device at the opening of the garment, the closure device including a zipper, a button or a hook and loop fastener; install a garment bust adjustment device in the armpit area on both sides of the garment, the bust adjustment device including a buckle, an elastic band, elastic fabric or a hook and loop fastener.

[0084] Depend on Figure 4 As can be seen, in this embodiment, both the serrated needle method and the lamination method can be used to fix the circulating pipe hose. The method of fixing the pipe hose in multiple blocks in parallel greatly improves production efficiency and quality. For the lamination method, each liquid circulating pipe hose loop does not need to be limited to a single planar area; it can be laid out across blocks to any desired location, realizing the open-front design of the liquid circulating human body heat exchange device. Through the reasonable layout of the liquid circulating pipe hose loops, the distributor and collector can also be installed in any desired location on the liquid circulating human body heat exchange device, not limited to installation under the armpit, which allows for a wider range of applications for the lamination method. Therefore, by applying the technology of this invention, the manufacturing process of liquid circulating human body heat exchange devices becomes more efficient, and some three-dimensional high-performance heat exchange garments can also be manufactured.

[0085] The manufacturing process of the liquid circulating human body heat exchange device described above, using a heat exchange vest as an example, can be applied to the manufacturing of liquid circulating human body heat exchange devices of any shape and structure. The only difference lies in the different pieces that can be disassembled depending on the garment structure. For example, a liquid circulating human body heat exchange garment top with a collar and sleeves can be disassembled into six pieces: collar, left sleeve, right sleeve, left front chest, right front chest, and back.

[0086] Furthermore, the connection of the liquid circulation pipe hose loop is not limited to the shoulder area; it can be achieved anywhere the pipe hose needs to be connected. For example, in a liquid circulation human heat exchange top with sleeves, the liquid circulation pipe hose loop on the sleeve can be connected to the pipe hose on the main body of the garment 1 at the seam of the two pieces, allowing the liquid inside the main body of the garment 1 to circulate into the sleeve.

[0087] Based on the description of the above related embodiments, for a liquid-circulating heat exchange garment with sleeves, this utility model provides a segmented liquid-circulating heat exchange device, the manufacturing principle of which is shown in the following steps:

[0088] (a) Design the main body structure of the garment 1, and decompose the main body of the garment 1 into multiple independent basic garment pieces such as sleeves, left front chest, right front chest, and back; design a front opening structure between the left front piece 11 and the right front piece 12;

[0089] (b) According to the heat exchange requirements, the liquid circulation pipe hose loops are arranged in a layout pattern on multiple independent garment base pieces such as sleeves, left front chest, right front chest, and back, with some of the preset paths extending to the edge areas of each garment base piece.

[0090] (c) Select a pipe hose connection device 5 that is compatible with the material of the pipe hose to be connected. The pipe hose connection device 5 is a flexible sleeve or a rigid sleeve, the inner diameter of which is adapted to the outer diameter of the pipe hose to be connected to form a tight fit.

[0091] (d) Fix the liquid circulation pipe hose to each garment base piece by lamination or sawtooth needle method, and leave a length at the end of the liquid circulation pipe hose loop in the edge area;

[0092] (e) Trim the garment base piece with the liquid circulation pipe hose loop to the preset size and sew it into a complete garment;

[0093] (f) At the seam of adjacent garment base pieces, insert the end of the hose to be connected into the two end cavities of the hose connection device 5, and form a liquid-tight joint by solvent bonding, ultrasonic welding or radio frequency welding, so that the liquid circulation hose loop forms a complete circulation loop across the pieces.

[0094] (g) Add fixing measures at pipe and hose connections: for the lamination method, cover the exposed pipe with adhesive lining material; for the serrated needle method, fix the exposed pipe and hose connections with needle and thread.

[0095] (h) Install a closure device at the opening of the garment, the closure device including a zipper, a button or a Velcro strap; install a garment bust adjustment device in the armpit area on both sides of the garment, the bust adjustment device including a buckle, an elastic band, elastic fabric or a Velcro strap;

[0096] (i) The end of the liquid circulation pipeline hose is connected to the corresponding sub-port of the distributor and the collector, and the input and output main pipeline hoses are connected to the main ports of the distributor and the collector.

[0097] Furthermore, after the main garment 1 is decomposed into basic garment pieces, if necessary, these basic garment pieces can be further decomposed into sub-garment pieces. Simultaneously, liquid circulation pipe hose loops can be fixed to each sub-garment piece using lamination or serrated stitching. Then, all the sub-garment pieces with the fixed liquid circulation pipe hose loops are sewn together, and the hoses to be connected on both sides are connected and run through the seams. This creates a complete basic garment piece with the fixed liquid circulation pipe hose loops.

[0098] Specifically, during the production and use of liquid circulating human body heat exchange equipment, the flexible pipes in the clothing are easily punctured by sharp objects. This invention also includes a repair structure, namely the pipe / flexible pipe connection device 5, used for repairing and connecting the damaged area of ​​the pipe / flexible pipe. The connection technology of this invention can be used to repair it, and the repair principle and steps are as follows:

[0099] (a) Cut and trim the damaged portion of the hose at the point of breakage;

[0100] (b) Select a pipe hose connection device 5 that is compatible with the material of the hose to be repaired. The pipe hose connection device 5 is a flexible sleeve whose inner diameter is adapted to the outer diameter of the hose to be repaired to form a tight fit. Figure 3 or Figure 5 As shown;

[0101] (c) Insert the cut ends of the pipe hose into the two end cavities of the pipe hose connection device 5 respectively, and form a liquid-tight joint by solvent bonding, ultrasonic welding or radio frequency welding.

[0102] (d) Selectively, additional fixation measures may be added to the repair site. For the lamination method, the exposed pipe may be covered with adhesive lining material. For the serrated needle method, the exposed pipe may be fixed with nails and thread.

[0103] Specifically, when the end faces of the pipes and hoses to be connected axially abut against each other, the pipe and hose connecting device 5 wraps around and presses against the outer circumferential surface of the abutting portion; in one embodiment, such as Figure 3 As shown, the end faces of the two hoses 25 and 26 to be connected in the pipe hose connection device 5 are in close contact.

[0104] Specifically, when there is an axial gap at the end face of the hose to be connected, the hose connecting device 5 simultaneously covers the outer circumferential surfaces of the two separate end faces, and a liquid-tight joint is formed by the interference fit between the inner wall of the sleeve and the outer wall of the hose to be connected; in another embodiment, such as Figure 5 As shown, the pipe hose connection device 5 connects the two pipe hoses with separate end faces together, thus serving as a bridging device.

[0105] In one embodiment, the connecting sleeve can be a rigid sleeve, which is used to obtain maximum support force. Although a rigid pipe is used, the connection technology of this utility model ensures that the fluid cross-sectional area at the connection point will not be reduced, thus not affecting the flow rate of the circulating liquid, which is also within the protection scope of this utility model.

[0106] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
