Description

Technical Field

[0001] The utility model relates to a phase change cold storage bag. Background Technique

[0002] Existing phase change cold storage bags are all composed of two parts: a phase change material and a packaging bag. The phase change material is a solid-liquid phase change material.

[0003] The working principle of the phase change cold storage bag is that when the external temperature is lower than the phase change solidification point of the phase change material, the phase change material releases heat, and the phase gradually changes from liquid to solid. When the phase change material completely becomes solid, the entire phase change cold storage bag completes heat release; when the external temperature is higher than the phase change melting point of the phase change material, the phase change material absorbs heat, and the phase gradually changes from solid to liquid. When the phase change material completely becomes liquid, the entire phase change cold storage bag completes heat absorption;

[0004] In application, the heat release process of the phase change cold storage bag is first used to complete cold storage, and then the heat absorption process of the phase change cold storage bag is used to achieve the purpose of cooling the target.

[0005] The phase change material in the existing phase change cold storage bag is a solid-liquid phase change material. When the phase change material cools the target object by absorbing heat, the phase of the phase change material changes from solid to liquid. Due to the action of gravity, it will gradually accumulate downward, and the phase change cold storage bag deforms, resulting in uneven cooling of the target object;

[0006] During the use of the phase change cold storage bag, one side is closely attached to the target object, and the other side faces the external environment. This will cause the phase change cold storage bag to additionally absorb external heat, resulting in waste of the cold quantity of some phase change materials and affecting the cooling effect on the target object;

[0007] The phase change cold storage bag generally uses aluminized material, with poor flexibility, poor comfort, and easy to damage;

[0008] The sealing performance of the phase change cold storage bag is relatively poor, and cold quantity is likely to be released externally, affecting the cooling effect. Content of the Utility Model

[0009] The purpose of the utility model is to provide a phase change cold storage bag to solve the problems of uneven cooling, easy waste of cold quantity, easy damage, and relatively poor sealing performance of the phase change cold storage bag mentioned in the above background technique.

[0010] To solve the above technical problems, the utility model provides the following technical solution: A phase change cold storage bag, including a first phase change cold storage bag body and a second phase change cold storage bag body. Clamping support plates and locking support plates are respectively arranged at the first phase change cold storage bag body and the second phase change cold storage bag body. The clamping support plates and the locking support plates cooperate with each other.

[0011] A sealing member is arranged at the locking support plate.

[0012] Among them, the buckling support plate and the locking support plate are sealed between the first phase change cold storage bag body and the second phase change cold storage bag body through a sealing member.

[0013] Preferably, both the first phase change cold storage bag body and the second phase change cold storage bag body include a heat insulation layer, a composite layer, an adsorption layer, and a temperature reduction layer arranged in sequence from outside to inside.

[0014] Preferably, the heat insulation layer, the composite layer, the adsorption layer, and the temperature reduction layer are respectively aerogel insulation, TPU composite fabric, porous sponge, and phase change material;

[0015] The phase change material is an organic phase change material, an inorganic phase change material, or a composite phase change material with a phase change melting point within 30°C.

[0016] Preferably, a clamping plate is provided at the buckling support plate, and a plurality of groups of clamping grooves are spaced apart at the clamping plate.

[0017] Preferably, a slot for inserting the clamping plate is opened at the locking support plate, and a plurality of groups of clamping plates are spaced apart at the slot.

[0018] Preferably, a peeling groove for separating the buckling support plate and the locking support plate is opened in the middle of the locking support plate and the buckling support plate.

[0019] Preferably, the sealing member includes an inner groove plate provided at the locking support plate, a receiving groove is opened at the inner groove plate, and a sealing rubber plate is slidably connected in the receiving groove.

[0020] Preferably, an airbag pad is provided inside the sealing rubber plate, and the shape of the airbag pad is an inverted water droplet shape.

[0021] Preferably, a plurality of groups of return springs are provided at the receiving groove, and the return springs are located between the sealing rubber plate and the inner groove plate.

[0022] Preferably, a fitting groove for clamping the sealing rubber plate is opened at the buckling support plate so that the locking support plate and the buckling support plate fit together.

[0023] Compared with the prior art, the beneficial effects of the present utility model are:

[0024] The present utility model improves the distribution and fixation method of the phase change material, and uses a high-density hydrophilic porous sponge or a high-density lipophilic porous sponge with a porosity of more than 90%, which plays an adsorption and support role. The porous structure of the sponge can fully adsorb the phase change material through capillary action, so that the phase change material is uniformly fixed in the pores of the porous sponge, ensuring uniform cooling of the target object by the phase change cold storage bag. At the same time, the high-density porous sponge has a higher hardness and can also play a role in supporting and fixing the overall shape and volume of the phase change cold storage bag; it avoids the problem of uneven cooling caused by the accumulation of the phase change material under the action of gravity, and ensures the uniform cooling effect on the target object.

[0025] Reduce cold energy waste: Optimize the design of the phase change cold storage bag. The set heat insulation aerogel is silica aerogel, which is attached to one side of the phase change cold storage bag, reducing the additional heat absorption caused by one side being closely attached to the target object while the other side faces the external environment, thereby reducing the waste of cold energy and improving the cooling efficiency.

[0026] Improve the flexibility and comfort of the material: Improve the material of the phase change cold storage bag, adopt TPU composite cloth, a material with better flexibility, improve the comfort during use, and reduce the risk of damage.

[0027] Enhance the sealing performance: Through the cooperation of the buckling support plate and the locking support plate and the use of seals, the sealing performance of the phase change cold storage bag is significantly improved, reducing the release of cold energy and ensuring the cooling effect.

[0028] Optimize the cold storage and heat release processes: By improving the fixation method of the phase change material and the structural design of the phase change cold storage bag, the cold storage and heat release processes are optimized, enabling the phase change material to maintain efficient and uniform performance during heat absorption and heat release.

[0029] Enhanced adaptability: By selecting phase change materials with different phase change melting points, the phase change cold storage bag can adapt to different temperature environments and application requirements, improving the applicability and flexibility of the product.

[0030] The phase change cold storage bag of the present utility model can more effectively utilize the cold energy of the phase change material, reduce the waste of energy, and has the advantages of environmental protection and energy saving. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Please refer to Figures 1-5 , the present utility model provides a phase change cold storage bag, including a first phase change cold storage bag body 100 and a second phase change cold storage bag body 200. The first phase change cold storage bag body 100 and the second phase change cold storage bag body 200 both include a heat insulation layer, a composite layer, an adsorption layer and a cooling layer arranged in sequence from outside to inside. The heat insulation layer, the composite layer, the adsorption layer and the cooling layer are respectively heat insulation aerogel, TPU composite cloth, porous sponge and phase change material; the phase change material is an organic phase change material, an inorganic phase change material or a composite phase change material with a phase change melting point within 30°C.

[0039] A fastening support plate 300 and a locking support plate 400 are respectively arranged at the first phase change cold storage bag body 100 and the second phase change cold storage bag body 200. The fastening support plate 300 and the locking support plate 400 cooperate with each other. A clamping plate 301 is arranged at the fastening support plate 300, and a plurality of groups of clamping grooves 302 are spaced apart at the clamping plate 301. A slot 401 for inserting the clamping plate 301 is formed at the locking support plate 400, and a plurality of groups of clamping plates 402 are spaced apart at the slot 401. A peeling groove 600 for separating the fastening support plate 300 and the locking support plate 400 is formed in the middle of the locking support plate 400 and the fastening support plate 300. A fitting groove 303 for clamping a sealing rubber plate 503 is formed at the fastening support plate 300, so that the locking support plate 400 and the fastening support plate 300 are mutually fitted.

[0040] A sealing member 500 is arranged at the locking support plate 400. The sealing member 500 includes a content groove plate 501 arranged at the locking support plate 400. An accommodation groove 502 is formed at the content groove plate 501, and a sealing rubber plate 503 is slidably connected in the accommodation groove 502. An airbag pad 504 is arranged inside the sealing rubber plate 503, and the shape of the airbag pad 504 is an inverted water droplet shape. A plurality of groups of return springs 505 are arranged at the accommodation groove, and the return springs 505 are located between the sealing rubber plate 503 and the content groove plate 501.

[0043] At the same time, the locking support plate 400 squeezes the content groove plate 501 into the fitting groove 303. The fitting groove 303 squeezes the return spring 505 located in the accommodation groove 502 through the sealing rubber plate 503. The return spring 505 contracts under force to generate an elastic force, which acts on the airbag pad 504 in the reverse direction. The sealing rubber plate 503 is squeezed to the fitting groove 303 through the airbag pad 504, filling the gap between the sealing rubber plate 503 and the fitting groove 303 to improve the sealing performance.
