Description

Technical Field

[0001] The invention belongs to the technical field of protective clothing structures, and in particular relates to a refrigeration mechanism for cooling clothing and a manufacturing process thereof. Background Art

[0002] In the extremely hot and humid working environment in summer, it is extremely important to protect the safety and comfort of power grid workers. Cooling suits are widely used as an effective personal protective equipment. Common cooling suits include liquid cooling suits, air cooling suits, and semiconductor cooling suits. Compared with other cooling suits, phase change cooling suits have the advantages of low cost, portability, and environmental protection. They absorb and store heat within a specific temperature range through built-in phase change materials (PCM), thereby achieving human body cooling. However, the existing phase change cooling suits still have many shortcomings in terms of packaging structure. The packaging structure of previous phase change cooling suits often uses a single material and a simple structural form, which makes it easy to have problems such as poor thermal stability and easy aging of packaging materials in high temperature environments, resulting in the heat transfer efficiency of phase change materials being hindered.

[0003] The packaging structure of the existing phase-change cooling suit also has limitations in terms of heat conduction efficiency. Due to the large thermal resistance between the packaging material and the phase-change material, the heat will be hindered during the transfer process, resulting in the overall cooling effect of the cooling suit being limited. This problem is particularly prominent in extremely high temperature and high humidity environments, making it difficult to meet the needs of operators for efficient cooling. In addition, due to the different heat production in different parts of the human body and the particularity of some parts (such as the armpits and head), they cannot directly contact the phase-change material for cooling, and the cooling effect is not outstanding. Summary of the invention

[0004] The embodiment of the present invention provides a refrigeration mechanism for cooling clothing and its manufacturing process, aiming to solve the technical problems that the existing phase change cooling clothing has limitations in heat conduction efficiency, the thermal resistance between the packaging material and the phase change material is large, resulting in the overall cooling effect of the cooling clothing being poor, and because different parts of the human body produce different amounts of heat, they cannot directly contact the phase change material for cooling, resulting in a poor cooling effect.

[0005] In a first aspect, an embodiment of the present invention provides a refrigeration mechanism for cooling clothing, comprising a container, a heat-insulating layer, a polyurethane film, a phase change material, a flexible heat-conducting pipe, a metal wire braid and a heat-absorbing layer, wherein the container has a accommodating cavity with an opening on one side; the heat-insulating layer is wrapped around the outer periphery of the container; the polyurethane film is connected to the opening of the container to close the accommodating cavity; the phase change material is placed in the accommodating cavity; one end of the flexible heat-conducting pipe is fixedly connected to a side of the polyurethane film away from the accommodating cavity, and the outer peripheral surface of the flexible heat-conducting pipe is attached to the polyurethane film; the metal wire braid is fixedly connected to the other end of the flexible heat-conducting pipe, and the metal wire braid is laid on a side of the polyurethane film away from the container; the heat-absorbing layer is arranged on a side of the metal wire braid away from the container;

[0006] The polyurethane film allows the skin to fit the phase change material, and when the phase change material is working, the cold at the phase change material is transferred to a specific part through the flexible heat-conducting pipe.

[0007] Compared with the prior art, the solution shown in the embodiment of the present application is that the metal wire braid is the main fabric of the cooling suit, and a container, a thermal insulation layer, a polyurethane film, and a phase change material are installed on the metal wire braid. When the operator works outdoors, the state change of the phase change material (for example, solid to liquid) can achieve the effect of heat absorption and cooling. Moreover, since the phase change material is placed in the container and the periphery of the container is provided with a thermal insulation layer, the working time of the phase change material can be extended and the cooling effect of the phase change material can be optimized. Moreover, since the container cavity has an opening and a polyurethane film is provided at the opening, the skin can be fitted. Phase change material is comfortable to wear and has a more obvious cooling effect. For positions that are not easily in contact with cooling suits (such as armpits), the cold at the phase change material can be transferred to specific positions through flexible heat pipes when the phase change material is working, ensuring that a good cooling effect can be obtained even without direct contact with the cooling suit. The heat absorption layer in the metal wire can make the cold energy of the phase change material evenly distributed, avoiding the phenomenon of "cold and hot in one area" when wearing cooling suits, and because the metal wire braid has a certain thermal conductivity, the cooling suit can have a cool feeling as a whole, optimizing the wearing experience.

[0008] In combination with the first aspect, in a possible implementation, a plurality of the flexible heat-conducting tubes are provided, one end of the plurality of the flexible heat-conducting tubes is fixed to the same preset point on the metal wire braid, and the other end is dispersed at different positions of the polyurethane film.

[0009] In combination with the first aspect, in a possible implementation, a plurality of the flexible heat-conducting tubes are provided, the plurality of the flexible heat-conducting tubes are spaced apart from each other, one end of the plurality of the flexible heat-conducting tubes is fixed at different preset points of the metal wire braid, and the other end is dispersed at different positions of the polyurethane film.

[0010] In combination with the first aspect, in a possible implementation manner, a textile electrode is further provided on the metal wire braid, and the textile electrode is used to stimulate acupoints.

[0011] In combination with the first aspect, in a possible implementation manner, the metal wire braid is a mesh braid.

[0012] In combination with the first aspect, in a possible implementation manner, the flexible heat-conducting pipe is a combination of one or more of a metal flexible pipe, a polymer flexible pipe, and a composite flexible pipe.

[0013] In combination with the first aspect, in a possible implementation manner, the phase change material is a combination of one or more organic materials, inorganic materials, and composite materials.

[0014] In combination with the first aspect, in a possible implementation manner, the container is a rectangular parallelepiped, and an inner wall at the opening of the container is further provided with a circle of installation steps for supporting the phase change material.

[0015] In a second aspect, an embodiment of the present invention further provides a manufacturing process for a refrigeration mechanism for cooling clothing, which is used to prepare the refrigeration mechanism for cooling clothing, comprising the following steps:

[0016] S10: establishing a physical model of the container, using 3D printing to integrally process and manufacture the container, and leaving an opening on a side wall of the container;

[0017] S20: sealing the opening of the container with a polyurethane film and filling the container with a phase change material;

[0018] S30: pasting a flexible heat-conducting pipe on the side of the polyurethane film facing away from the receiving member, and pasting a metal wire braid on the end of the flexible heat-conducting pipe;

[0019] S40: a heat-insulating layer is provided on the outer periphery of the container, and a heat-absorbing layer is provided on the side of the metal wire braid facing away from the container.

[0020] Compared with the prior art, the solution shown in the embodiment of the present application can obtain a container with precise dimensions according to the established physical model through 3D printing technology, so that the capacity of the phase change material in the container can be controlled to be constant, avoiding too little phase change material resulting in an insignificant cooling effect or too much phase change material resulting in a waste of material; the refrigeration mechanism for cooling clothing prepared by the method described in this embodiment can optimize the cooling effect, extend the cooling time, and can also well cool parts such as the armpits that are not in direct contact with the cooling clothing, thereby providing a better wearing experience.

[0021] In combination with the second aspect, in a possible implementation, the flexible heat-conducting pipe includes a plurality of tube bodies, and the plurality of tube bodies are wound together by intarsia knitting, and the density of circles per 10 mm is 7 to 9 units.

[0037] Please also read Figures 1 to 3 , the refrigeration mechanism for cooling clothes provided by the present invention is now described. The refrigeration mechanism for cooling clothes includes a container 10, a heat-insulating layer 20, a polyurethane film 30, a phase change material 40, a flexible heat-conducting pipe 50, a metal wire braid 60 and a heat-absorbing layer 70. The container 10 has a container cavity 11 with an opening on one side; the heat-insulating layer 20 is wrapped around the outer periphery of the container 10; the polyurethane film 30 is connected to the opening of the container 10 to close the container cavity 11; the phase change material 40 is placed in the container cavity 11; one end of the flexible heat-conducting pipe 50 is fixedly connected to the side of the polyurethane film 30 away from the container cavity 11, and the outer peripheral surface of the flexible heat-conducting pipe 50 is attached to the polyurethane film 30; the metal wire braid 60 is fixedly connected to the other end of the flexible heat-conducting pipe 50, and the metal wire braid 60 is laid on the side of the polyurethane film 30 away from the container 10; the heat-absorbing layer 70 is arranged on the side of the metal wire braid 60 away from the container 10;

[0038] The polyurethane film 30 allows the skin to fit the phase change material 40 , and when the phase change material 40 is working, the cold energy at the phase change material 40 is transferred to a specific part through the flexible heat pipe 50 .

[0039] Optionally, the polyurethane film 30 is a TPU film, which is a thermoplastic TPU elastomer and is made of MDI (diphenylmethane diisocyanate) containing NCO (isocyanate) functional groups, POLYOL (polyether polyol) containing OH (hydroxyl) functional groups, and 1.4BG (1.4 butanediol), which are made by extrusion mixing. Due to its good elasticity, excellent physical properties, and various mechanical strengths, it is widely used in processing methods such as injection, extrusion, calendering, and dissolution into solution-type resins.

[0040] Compared with the prior art, the refrigeration mechanism for cooling clothing provided in this embodiment has a metal wire braid 60 as the main fabric of the cooling clothing, and a container 10, a thermal insulation layer 20, a polyurethane film 30, and a phase change material 40 are installed on the metal wire braid 60. When the operator is working outdoors, the state change of the phase change material 40 (for example, solid to liquid) can achieve the effect of heat absorption and cooling. Moreover, since the phase change material 40 is placed in the container 10 and the outer periphery of the container 10 is provided with the thermal insulation layer 20, the working time of the phase change material 40 can be extended and the cooling effect of the phase change material 40 can be optimized. Moreover, since the accommodating cavity 11 has an opening and a polyurethane film 30 is provided at the opening, the accommodating cavity 11 has an opening and a polyurethane film 30 is provided at the opening. The ester film 30 can make the phase change material 40 fit the skin, making it comfortable to wear and having a more obvious cooling effect. In addition, for positions that are not easily in contact with the cooling suit (such as the armpits), the cold at the phase change material can be transferred to the specific position through the flexible heat pipe 50 when the phase change material 40 is working, thereby ensuring that a good cooling effect can be obtained even without direct contact with the cooling suit. The heat absorption layer 70 in the metal wire can make the cold amount of the phase change material 40 evenly distributed, thereby avoiding the phenomenon of "cold in one area and hot in another" when wearing the cooling suit. In addition, since the metal wire braid 60 has a certain thermal conductivity effect, the cooling suit as a whole can present a cool feeling, thereby optimizing the wearing experience.

[0041] In some embodiments, a specific implementation of the flexible heat pipe 50 can be as follows: Figure 1 See the structure shown. Figure 1 A plurality of flexible heat-conducting pipes 50 are provided, one end of each of the plurality of flexible heat-conducting pipes 50 is fixed to the same preset point on the metal wire braid 60 , and the other end is distributed at different positions of the polyurethane film 30 .

[0042] Multiple flexible heat pipes 50 can transfer the cold from the same phase change material 40 to the same preset point of the metal wire braid 60, so that the cooling effect of the preset point is better. According to the different heat generation of different parts of the body, different numbers of flexible heat pipes 50 can be set at each preset point, and then cooling can be performed according to specific heating needs, with a better cooling effect.

[0043] It should be noted that the multiple flexible heat-conducting tubes 50 fixed on the same phase change material 40 can all be fixed at the same point of the metal wire braid 60, or can be divided into several parts, each part includes multiple flexible heat-conducting tubes 50, and the flexible heat-conducting tubes 50 of different parts are fixed at different points of the metal wire braid 60; for example, five flexible heat-conducting tubes 50 are fixed on a phase change material 40, of which the ends of three flexible heat-conducting tubes 50 are fixed at a preset point of the metal wire braid 60, and the ends of the other two flexible heat-conducting tubes 50 are fixed at another point of the metal wire braid 60.

[0044] In a specific implementation, the multiple flexible heat-conducting pipes 50 on the same phase change material 40 may be distributed radially.

[0045] In some embodiments, a modified implementation of the above-mentioned flexible heat-conducting pipe 50 can be as follows: Figure 2 See the structure shown. Figure 2 There are multiple flexible heat-conducting pipes 50 , and the multiple flexible heat-conducting pipes 50 are spaced apart from each other. One end of the multiple flexible heat-conducting pipes 50 is fixed to different preset points of the metal wire braid 60 , and the other end is dispersed at different positions of the polyurethane film 30 .

[0046] In a specific implementation, the multiple flexible heat-conducting pipes 50 on the same phase change material 40 may be parallel to each other or may be at a certain angle between each other but not in contact.

[0047] Multiple flexible heat-conducting pipes 50 transfer the cold from the same phase change material 40 to different points on the metal wire braid 60, which not only allows the area of ​​the skin that is in direct contact with the phase change material 40 to be cooled, but also the parts that are not in contact with the phase change material 40 can be cooled through the flexible heat-conducting pipes 50. Through the reasonable distribution of the fixed ends of the phase change material 40 and the flexible heat-conducting pipes 50 on the metal wire braid 60, different positions of the metal wire braid 60 can be cooled evenly, thereby optimizing the cooling effect.

[0048] Specifically, the flexible heat-conducting pipe 50 is a combination of one or more of a metal flexible pipe, a polymer flexible pipe, and a composite flexible pipe.

[0049] The metal flexible tube is made of metal wires with good heat conduction effect and soft texture. The metal wires are spirally wound to form a flexible tube, which is then fixed on the polyurethane film 30 for heat transfer.

[0050] The polymer flexible tube is a polymer support with a heat-conducting effect, such as diatomaceous earth fiber, polyesterimide fiber, etc. The fiber is woven or knitted into a tube, and then fixed on the polyurethane film 30 for heat transfer.

[0051] The composite flexible pipe is, for example, a composite material formed by mixing graphene and polymer into fibers and then weaving them into the flexible heat-conducting pipe 50 , or a metal wire and polyesterimide fiber are woven and mixed to form the flexible heat-conducting pipe 50 .

[0052] It should be noted that although the flexible heat-conducting pipe 50 is in a tubular shape, its diameter is relatively small, and because it is a flexible structure, it can avoid abrasion of the skin when wearing cooling clothing, thereby improving wearing comfort.

[0053] In some embodiments, an improved embodiment of the above-mentioned wire braid 60 can be adopted as follows Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 A textile electrode 61 is also provided on the metal wire braid 60, and the textile electrode 61 is used for stimulating acupuncture points.

[0054] Since outdoor workers usually perform physical work, they usually have symptoms such as shoulder pain. When the workers wear cooling clothes, they can manually press the textile electrodes 61, or when they sit while wearing the cooling clothes, the textile electrodes 61 can stimulate the corresponding acupoints on the workers' bodies, thereby relieving symptoms such as shoulder pain.

[0055] The textile electrode 61 in this embodiment can be pasted on the metal wire braid 60, or directly embedded in the metal wire braid 60. The textile electrode 61 is a metal sphere with a smooth surface to avoid scratches when massaging acupuncture points.

[0056] In some embodiments, a specific implementation of the above-mentioned metal wire braid 60 can be as follows Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 , the metal wire braid 60 is a mesh braid.

[0057] The metal wire braid 60 can feel cool as a whole under the action of the phase change material 40 and the heat pipe. However, if the metal wire braid 60 is too thick, it will still cause the wearer to generate heat and be unable to dissipate it. By setting the metal wire braid 60 to a mesh structure, the wearer's heat can be dissipated and it can also fit the wearer's skin. The combination of the two has a more obvious cooling effect on the wearer and is more comfortable to wear.

[0058] Specifically, the phase change material 40 is one or a combination of organic material, inorganic material, and composite material.

[0059] Organic materials include water and paraffin; inorganic materials include graphite, graphene and carbon fiber; composite materials are a mixture of organic and inorganic materials. By using one or more of these materials in combination, for example, using different phase change materials 40 in different parts of the body, the cooling effects of different phase change materials 40 can be matched with the heat generation of the body parts, thereby achieving a better cooling effect.

[0060] In some embodiments, an improved embodiment of the container 10 can be as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The container 10 is a rectangular parallelepiped, and the inner wall of the opening of the container 10 is also provided with a circle of installation steps 12 for supporting the phase change material 40.

[0061] The phase change material 40 can be packed in a bag, which is convenient for mass production. After the phase change material 40 packed in the bag is placed in the container 10, when it is worn, the installation step 12 can support the phase change material 40 to prevent it from falling out of the container 10, making it more reliable to use.

[0062] By providing the installation step 12 , the contact area between the container 10 and the polyurethane film 30 is larger, so the polyurethane film 30 is more firmly fixed to the opening of the container 10 .

[0063] As a deformable installation method of the phase change material 40, the phase change material 40 can also be directly filled in the accommodating cavity 11. By setting small holes on the polyurethane film 30, the internal phase change material 40 can be easily replaced. It is easy to understand that due to the elasticity of the polyurethane film 30 itself, when the small hole is small enough, it can ensure that the phase change material 40 will not be left out during normal use. However, a closed film can also be pasted at the small hole just in case. When the phase change material 40 needs to be replaced, the closed film can be torn off.

[0064] Optionally, the container 10 is a rectangular parallelepiped structure, with a maximum length of 15 cm, a maximum width of 10 cm, and a maximum height of 8 cm, that is, the maximum volume of the container 10 is length*width*height=(15*10*8) cm 3 The rectangular structure has many edges and corners. In order to optimize the wearing experience, the corners, edges and other positions of the rectangular structure can also be rounded.

[0065] Based on the same inventive concept, the embodiment of the present application also provides a manufacturing process for a refrigeration mechanism for cooling clothing, which is used to prepare the refrigeration mechanism for cooling clothing, and includes the following steps:

[0066] S10: establishing a physical model of the container 10, using 3D printing to integrally manufacture the container 10 and leaving an opening on the side wall of the container 10;

[0067] S20: sealing the polyurethane film 30 at the opening of the container 10, and filling the phase change material 40 into the container 10;

[0068] S30: Pasting a flexible heat-conducting pipe 50 on the side of the polyurethane film 30 facing away from the receiving member 10, and pasting a metal wire braid 60 on the end of the flexible heat-conducting pipe 50;

[0069] S40 : a heat-insulating layer 20 is disposed on the outer periphery of the container 10 , and a heat-absorbing layer 70 is disposed on the side of the wire braid 60 facing away from the container 10 .

[0070] The process of placing the phase change material 40 in the container 10 is as follows:

[0071] (1) First, the phase change material 40 is melted into a liquid state;

[0072] (2) evacuating the accommodating chamber 11 in the accommodating member 10;

[0073] (3) Filling the liquid phase change material 40 into a filling device (such as a pressure pump, etc.);

[0074] (4) Punch holes in the polyurethane film 30 and fill the phase change material 40 into the accommodating cavity 11 using a filling device.

[0075] Compared with the prior art, the manufacturing process of the refrigeration mechanism for cooling clothing provided in the present embodiment can obtain a container 10 of precise dimensions according to an established physical model through 3D printing technology, so that the capacity of the phase change material 40 in the container 10 can be controlled to be constant, thereby avoiding the situation where too little phase change material 40 has an insignificant cooling effect or too much phase change material 40 causes a waste of material; the refrigeration mechanism for cooling clothing prepared by the method described in the present embodiment can optimize the cooling effect, extend the cooling time, and can also well cool parts such as the armpits that are not in direct contact with the cooling clothing, thereby providing a better wearing experience.

[0076] In some embodiments, a specific implementation of the flexible heat pipe 50 is:

[0077] The flexible heat-conducting pipe 50 includes a plurality of pipe bodies, and the plurality of pipe bodies are wound together by intarsia knitting, and the density of circles per 10 mm is 7 to 9 units.

[0078] Intarsia knitting is a knitting technique that embeds yarns of other materials or colors into knitted fabrics to create patterns or installation effects.

[0079] The flexible heat-conducting pipe 50 can be fixed on the metal wire braid 60 by using the intarsia knitting process, and the flexible heat-conducting pipe 50 on the metal wire braid 60 located at the polyurethane film 30 can be directly attached to the position of the phase change material 40, so that the cold air can be transferred to the free end of the flexible heat-conducting pipe 50 when worn, thereby achieving fixed-point cooling.

[0080] It should be noted that, for example, the density of circles per 10 mm is 9 units, that is, the flexible heat-conducting pipe 50 is in a spiral shape on the metal wire braid 60 , and there are 9 circles in the spiral shape per 10 mm length.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
