Description

Technical Field

[0001] The present invention relates to the technical field of cooling systems, and in particular to a cold compress patch assembly and a preparation method and application thereof. Background Art

[0002] Based on the relationship between ambient temperature and human thermal balance, living environments above 35°C and production environments above 32°C are generally considered high-temperature environments. High temperatures can cause abnormal changes in human physiological functions, particularly those related to temperature regulation, water and salt metabolism, and blood circulation, endangering worker safety and causing unnecessary economic losses.

[0003] People working outdoors in non-air-conditioned environments, especially those who work continuously in high-temperature environments, such as construction workers working under the scorching sun and maintenance personnel performing maintenance work outdoors at height, often have to overcome various discomforts caused by the high temperatures to continue working for a period of time. When wearing ordinary clothing in high-temperature conditions, people sweat. Sweat diffuses and transfers to the surface of the clothing, and evaporation of sweat removes some heat. However, sweat evaporation provides a limited evaporation source, and therefore the amount of heat removed is also limited. Especially when working in high-temperature environments for a period of time, ordinary clothing cannot achieve the cooling effect required for a certain period of time.

[0004] In order to solve the above problems, cooling and air-conditioning clothing for achieving human body temperature regulation has appeared in the prior art. For example, the Chinese invention patent with the announcement number CN220343733U, "A phase-change cooling clothing with good cooling effect", uses a water pump to flow ice water into a liquid circulation pipeline and then into an ice water bag, so that the ice water absorbs the heat in the body during the circulation process, achieving the cooling effect of the cooling clothing. However, in the above structural scheme, there is a lack of consideration for the loss of liquid medium. Since the liquid medium may micro-permeate or micro-evaporate through the pipeline, the capacity of the circulating liquid medium in the refrigeration body is reduced, resulting in poor circulation and affecting the transmission of cold energy. In addition, the liquid medium may also cause the loss of cold energy in the process of entering and exiting the ice water bag through the pipeline, which is not conducive to improving the cooling efficiency of the refrigeration equipment.

[0005] To further reduce heat loss during the process of liquid medium entering and exiting the cold compress bag through pipes and other means, a new cooling technology has emerged in the prior art, which directly transfers cold energy to the cold storage material inside the cold compress bag through a cold conduction block. For example, Chinese invention patent publication number CN119289548A is titled "A Semiconductor Refrigeration Mechanism." However, since direct cold energy transfer is generally achieved through a metal cold conduction block, the metal cold conduction block will have more or less residual burrs (i.e., burrs, flash, etc.) on its surface after processing. Such burrs can easily pierce or crush the flexible cold compress bag during subsequent processing, causing leakage of the cold storage material inside the bag, seriously affecting product yield and reliability. Summary of the Invention

[0006] The purpose of the present invention is to provide a cold compress patch assembly and a preparation method thereof, which greatly reduces the risk of damage to the cold compress bag, thereby improving product yield and reliability, and overcoming the shortcomings of the existing technology.

[0046] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0047] This technical solution provides a method for preparing a cold compress patch assembly, comprising the following steps:

[0048] Processing: preparing a cooling block 1; wherein the cooling block 1 comprises a cooling portion 11 and a cooling transfer portion 12, wherein the cooling portion 11 is used to be attached to the cooling end of the refrigerator;

[0049] Wrapping: placing the cooling block 1 in an injection molding machine, and injection molding the plastic wrapping ring 2 on the outside of the cooling portion 12; wherein the plastic wrapping ring 2 wraps the top, side walls and bottom of the cooling portion 12;

[0050] Filling: Fill the cold compress bag 3 with cold storage material, place the cold transfer part 12 wrapped with the plastic covering ring 2 into the interior of the cold compress bag 3, and then fit the bag opening of the cold compress bag 3 with the surface of the plastic covering ring 2, and seal to obtain a cold compress patch assembly.

[0051] In order to reduce the risk of damage to the cold compress bag 3 and improve product yield and reliability, this technical solution proposes a method for preparing a cold compress patch assembly, the flow diagram of which is shown in FIG. Figure 1 As shown, the prepared cold compress assembly includes a cold conducting block 1, a plastic covering ring 2 and a cold compress bag 3. Figure 2-9 As shown, the cold conduction part 11 is used to be attached to the cooling end of the refrigerator, so that the cold energy generated by the refrigerator can pass through the cold conduction part 11 and the cold transfer part 12 in sequence, and be transferred to the cold storage material (such as water, gel, etc. that can store and release cold energy) in the cold compress bag 3 through the plastic sheathing ring 2 and / or the surface of the cold transfer part 12 exposed to the plastic sheathing ring 2.

[0052] In particular, this solution obtains a plastic wrapping ring 2 by injection molding on the outside of the cold transfer part 12, and uses the plastic wrapping ring 2 to wrap the top, side walls and bottom of the cold transfer part 12 in the cold conduction block 1, so that the cold transfer part 12 and the cold compress bag 3 can be isolated by the plastic wrapping ring 2, avoiding direct contact between the cold transfer part 12 and the cold compress bag 3, and preventing the burr of the cold conduction block 1 from piercing or crushing the flexible cold compress bag 3 during subsequent processing, resulting in leakage of the cold storage material in the bag.

[0053] It should be noted that the plastic covering ring 2 can be selected to partially or completely cover the top / bottom of the cold transfer part 12 under the premise of comprehensively considering factors such as the product's cold transfer effect, production cost and transportation effect. This solution is not limited here.

[0054] It should be further explained that the cold conduction block 1 in this embodiment can preferably be an aluminum block and manufactured by extrusion molding; the plastic sheathing ring 2 can preferably be made of a synthetic polymer material such as polyvinyl chloride (PVC) or polyamide (PA, i.e., nylon) and is cast on the exterior of the cold conduction portion 12 by injection molding. Furthermore, during the injection step, the contact between the opening of the cold compress bag 3 and the surface of the plastic sheathing ring 2 can be achieved by adhesive bonding or by melt pressing to achieve a seal.

[0055] Preferably, the refrigerator of this embodiment can be a semiconductor refrigeration chip. Specifically, the semiconductor refrigeration chip is made using the Peltier effect. The Peltier effect refers to the phenomenon that when a direct current passes through a galvanic couple composed of two semiconductor materials, one end of the galvanic couple absorbs heat and the other end releases heat. In other words, the semiconductor refrigeration chip is made of two semiconductor materials, forming a hot end and a cold end. The cold end continuously absorbs heat, achieving cooling, while the hot end continuously releases heat, achieving heat dissipation.

[0056] Further, in the processing step, the cross-sectional area of ​​the cooling portion 12 is greater than or equal to the cross-sectional area of ​​the cooling portion 11;

[0057] Also included is a milling groove, the milling groove being located between the machining and the cladding:

[0058] Milling groove: using a milling cutter to mill an upper anti-scratch groove 1221 on the top surface 122, and the upper anti-scratch groove 1221 is located between the cooling portion 11 and the cooling portion 12, and the groove wall of the upper anti-scratch groove 1221 is a smooth surface;

[0059] In the covering step, the plastic covering ring 2 completely covers the top surface 122 of the cold transfer portion 12 , and the plastic covering ring 2 fills the upper anti-scratch groove 1221 .

[0060] To further reduce the risk of damage to the cold pack 3, this solution also features a smooth upper anti-scratch groove 1221 milled between the cold conduction portion 11 and the cold transfer portion 12, creating a continuous and smooth connection surface between the two portions. Furthermore, the coating step ensures that the inner top wall of the injection-molded plastic sheath ring 2 features a protruding first ridge 21 that matches the shape of the upper anti-scratch groove 1221, preventing the plastic sheath ring 2 from falling off the cold conduction block 1.

[0061] Preferably, the upper anti-scratch groove 1221 extends along the length direction of the cold transfer portion 12 and passes through the cold transfer portion 12 .

[0062] Further description, the milling groove also includes:

[0063] A milling cutter is used to mill out lower anti-scratch grooves 1211 on both sides of the bottom of the cooling portion 12, and the lower anti-scratch grooves 1211 are located at the edge of the bottom surface 121 of the cooling portion 12, and the groove walls of the lower anti-scratch grooves 1211 are smooth surfaces;

[0064] During the coating step, the plastic coating ring 2 fills the lower anti-scratch groove 1211 .

[0065] To further reduce the risk of damage to the cold pack 3, this solution also features a smooth, lower anti-scratch groove 1211 milled into the bottom edge of the cold transfer portion 12, resulting in a continuous, smooth bottom edge. Similarly, the encapsulation step ensures that the inner bottom wall of the injection-molded plastic sheath ring 2 features a second protruding ridge 22 that matches the shape of the lower anti-scratch groove 1211, preventing the plastic sheath ring 2 from falling off the cold transfer block 1.

[0066] Preferably, the lower anti-scratch groove 1211 extends along the length direction of the cold transfer portion 12 and passes through the cold transfer portion 12 .

[0067] Further description, the milling groove also includes:

[0068] A milling cutter is used to mill an anti-slip groove 1222 on the top surface 122, and the anti-slip groove 1222 is located outside the upper anti-scratch groove 1221; the anti-slip groove 1222 includes a connecting portion 1222a and a protruding portion 1222b that are connected in sequence from top to bottom, and the width of the protruding portion 1222b is greater than the width of the connecting portion 1222a;

[0069] During the covering step, the plastic covering ring 2 fills the anti-slip groove 1222 .

[0070] In a more preferred embodiment of the present technical solution, in order to improve the bonding between the plastic sheathing ring 2 and the cold transfer portion 12, the present solution further mills anti-slip grooves 1222 on both sides of the top surface 122, and optimizes the width of the connecting portion 1222a and the width of the protruding portion 1222b in the anti-slip groove 1222, which is more conducive to preventing the plastic sheathing ring 2 from separating from the cold transfer portion 12. Similarly, the sheathing step causes the inner top wall of the plastic sheathing ring 2 obtained by injection molding to protrude with a third ridge 23 that matches the shape of the anti-slip groove 1222, making it difficult for the plastic sheathing ring 2 to fall off the cold transfer block 1.

[0071] Preferably, the anti-slip groove 1222 is in an inverted T-shape.

[0072] Preferably, the anti-slip groove 1222 extends along the length direction of the cold transfer portion 12 and passes through the cold transfer portion 12 .

[0073] To further illustrate, in the wrapping step, the plastic wrapping ring 2 is wrapped around the top, side walls and bottom edges of the cold transfer portion 12, and the bottom surface 121 of the cold transfer portion 12 is exposed at the bottom of the plastic wrapping ring 2, and the bottom surface 121 is flush with the lower surface of the plastic wrapping ring 2.

[0074] As a better solution of this technical solution, this solution also further improves the structural relationship between the bottom surface 121 and the plastic sheathing ring 2, so that the bottom surface 121 is exposed at the bottom of the plastic sheathing ring 2. Since the thermal conductivity of the plastic sheathing ring 2 is generally lower than that of the cooling block 1 used to transfer cold, this characteristic is conducive to changing the heat flow distribution of the cooling block 1. Compared with the large area of ​​exposure of the cooling part in the Chinese invention patent with publication number CN119289548A to achieve the transfer of cold, the setting of the plastic sheathing ring 2 in this solution will actually reduce the effective heat conduction area between the cooling block 1 and the cold storage material, so that the transferred cold is mainly concentrated on the bottom surface 121 exposed to the plastic sheathing ring 2, which is conducive to forming a larger temperature difference gradient between the cold storage material and human skin, thereby enhancing the local cold intensity. Thanks to the optimization of the heat conduction mechanism brought about by the structural improvement of this solution, it is more conducive to improving the cooling effect of the cold compress assembly and better meeting the cooling needs of the user.

[0075] To further illustrate, the cold compress bag 3 includes an inner bag 31 and an outer bag 32 which are sequentially arranged from the inside to the outside;

[0076] The perfusion specifically comprises the following steps:

[0077] The cold transfer part 12 wrapped with the plastic covering ring 2 is placed inside the inner bag 31; the bag opening of the inner bag 31 is melted and pressed with the surface of the plastic covering ring 2, and then sealed to obtain an intermediate package;

[0078] The outer bag 32 is poured with cold storage material, and the inner bag 31 of the intermediate package is immersed in the cold storage material. The bag opening of the outer bag 32 and the surface of the inner bag 31 are melted and pressed together, and sealed to obtain a cold compress assembly.

[0079] In another better embodiment of the present technical solution, the present solution also designs the cold compress bag 3 as a "double-bag nested" form, so that the inner bag 31 and the outer bag 32 together form a receiving cavity 301 for accommodating the cold storage material, completely avoiding direct contact between the cooling block 1 and the outer bag 32, and more effectively preventing the leakage of the cold storage material in the receiving cavity 301, thereby improving product yield and reliability.

[0080] Preferably, the thickness of the inner bag 31 is 0.3 mm, which can ensure the effective transfer of cold energy while preventing leakage.

[0081] Preferably, the melt pressing is high frequency pressing.

[0082] A cold compress patch assembly is prepared using the above-mentioned preparation method of the cold compress patch assembly.

[0083] The cold compress patch assembly produced by this solution can greatly reduce the risk of damage to the cold compress bag while ensuring effective transmission of cold, thereby improving product yield and reliability.

[0084] This solution also proposes an application of the above-mentioned cold compress patch assembly in cooling clothing.

[0085] In a specific embodiment, the cooling suit includes a semiconductor refrigeration sheet and the above-mentioned cold compress patch assembly, and the cold end surface of the semiconductor refrigeration sheet is in contact with the cooling block 1.

[0086] This solution also proposes an application of the above-mentioned cold compress patch assembly in a cooling system for special electronic equipment.
