For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] The following is combined with Figures 1 to 4 The technical solution of the utility model is further illustrated by specific implementation methods.

[0025] like Figure 1 and Figure 2 As shown, a water diffusion layer includes a liquid-absorbing paper 1, a vaporization net 2 and a breathable cotton 3; the liquid-absorbing paper 1, the vaporization net 2 and the breathable cotton 3 are stacked in sequence, and the liquid-absorbing paper 1 is provided with a diffusion texture; the vaporization net 2 forms a liquid vaporization space between the liquid-absorbing paper 1 and the breathable cotton 3; the breathable cotton 3 is used to expand the diffusion area of ​​the liquid.

[0026] In the refrigeration module, the interior of the refrigeration module is in a vacuum state, and the purpose of refrigeration is achieved by liquid vaporization. In order to effectively increase the vaporization rate of the liquid and achieve the effect of rapid refrigeration. This scheme proposes a water expansion layer, the absorbing paper 1, the vaporization net 2 and the breathable cotton 3 are stacked in sequence. Preferably, the absorbing paper 1 is provided with a diffusion texture, and the diffusion texture is formed by an embossing process. The diffusion texture is leather texture or linen texture or is composed of regularly arranged concave and convex patterns. The diffusion texture quickly diffuses and extends the liquid along the texture to avoid excessive local water accumulation and thus affect the cooling effect; the vaporization net 2 expands the vaporization area of ​​the liquid, provides an effective vaporization space for the liquid, and thus accelerates the rate of liquid vaporization; the breathable cotton 3 further diffuses the unvaporized liquid, reduces the difficulty of liquid vaporization, and achieves liquid vaporization better and faster. The combination of the absorbent paper 1, the vaporization net 2 and the breathable cotton 3 can quickly diffuse local liquid, increase the cooling area, and evenly distribute the cold energy. The liquid is continuously vaporized while diffusing, ensuring that the refrigeration module can achieve a fast and stable cooling effect. The refrigeration module has a simple structure, low cost, and is easy to produce.

[0027] Preferably, the absorbent paper 1 is made of raw pulp paper; the lateral liquid absorption height of the raw pulp paper is greater than 10 mm / 100 s, and the number of layers of the raw pulp paper is single or multiple.

[0028] Specifically, the absorbent paper 1 is composed of raw pulp paper, which is not easily damaged after absorbing water, has good stability during the water absorption process, and has a lateral liquid absorption height of >10mm / 100s, which can quickly diffuse the liquid to the vaporization network 2. The raw pulp paper has a single layer or multiple layers to ensure that the liquid can be quickly absorbed and dispersed.

[0029] Preferably, the vaporization network 2 is made of PE or PP material; the vaporization network is arranged in a crisscross grid, and a plurality of the grids are used to provide vaporization space for the liquid.

[0030] Specifically, the vaporization net 2 is made of PE or PP material, which has good stability and is not easy to soften or deform; the vaporization net 2 is arranged in a criss-cross grid, which can effectively separate the liquid in the blotting paper 1 into several small areas, and is used to provide space for liquid vaporization. Preferably, the mesh number of the PE net is 9 meshes, which is conducive to the stability and uniformity of liquid vaporization.

[0031] Preferably, the breathable cotton 3 is composed of PP cotton; the air permeability of the PP cotton is ≥200mm / s, and the filtration accuracy is 0.5um.

[0032] Specifically, due to the limited moisture absorption capacity of the wicking paper 1, excess liquid will precipitate on the surface, which is not conducive to vaporization. The breathable cotton 3 re-diffuses the liquid precipitated on the wicking paper 1 and the vaporization net 2, further expanding the diffusion area of ​​the liquid, and can remove certain impurity particles, thereby improving the quality and purity of the water vapor. In addition, the water vapor after the liquid is vaporized can pass through the PP cotton and then be absorbed by the absorption layer of the refrigeration module.

[0033] Preferably, the thickness of the vaporization net 2 is 0.2-2 mm; the thickness of the breathable cotton 3 is 1-2 mm.

[0034] Specifically, the size of the vaporization space affects the rate of vaporization. If the thickness of the vaporization net 2 is too thick, the liquid will be difficult to circulate after vaporization, causing water vapor to accumulate and return to a liquid state; if the thickness of the vaporization net 2 is too thin, the liquid will vaporize too quickly, and the water vapor will not have time to be adsorbed by the adsorption layer of the refrigeration module, causing local water vapor accumulation and excessive pressure, and the remaining liquid cannot meet the conditions for vaporization. In addition, when the thickness of the breathable cotton 3 is too thick, it will be difficult for water vapor to pass through; when the thickness is too thin, the precipitated liquid cannot be locked. Preferably, the thickness of the vaporization net 2 is 0.2 to 2 mm, and the thickness of the breathable cotton 3 is 1 to 2 mm, so that the liquid is vaporized as much as possible in the vaporization space formed by the absorbing paper 1, the vaporization net 2 and the breathable cotton 3, reducing the influence of accumulating liquid on the refrigeration effect.

[0035] Preferably, the absorbent paper 1, the vaporization net 2 and the breathable cotton 3 are heat-sealed at the edges 4 by heat sealing or ultrasonic process, and the heat-sealed edges 4 are at least two sides, and the heat-sealed edges 4 on both sides are symmetrically arranged.

[0036] Specifically, Figure 3 As shown, the absorbent paper 1, the vaporization net 2 and the breathable cotton 3 are heat-sealed by heat sealing or ultrasonic heat sealing to form a sealed seal to achieve the connection of the three-layer structure. The heat-sealed edges 4 are at least two sides, and the heat-sealed edges 4 on both sides are symmetrically arranged to ensure the firmness of the connection between the absorbent paper 1, the vaporization net 2 and the breathable cotton 3 to prevent them from falling off, deflecting or warping when placed in the refrigeration module.

[0037] In some embodiments, the absorbent paper 1 is a PP cotton layer. The PP cotton, the vaporization net 2 and the breathable cotton 3 are stacked in sequence, the breathable cotton 3 diffuses the liquid and plays a filtering role, and the vaporization net 3 divides the liquid into several small areas, thereby improving the efficiency of liquid vaporization, and the overall structure is simpler.

[0038] It should be noted that the utility model also provides a refrigeration module, including a barrier shell 01, a switch part 02, a first sealing bag 03, a cooling layer 04, a water expansion layer 05, a water blocking sheet 06, a heat preservation layer 07, an absorption layer 08, a second sealing bag 09 and a sealing film 010;

[0039] Specifically, Figure 4As shown, in the barrier shell 01, the switch part 02, the first sealing bag 03, the cooling layer 04, the water expansion layer 05, the water blocking sheet 06, the heat preservation layer 07, the absorption layer 08 and the second sealing bag 09 are stacked in sequence, and the bottom opening of the barrier shell 01 is covered and sealed by the sealing film 010. After the refrigeration module is evacuated and pressurized into a vacuum state, a vacuum sealed cavity is formed in the barrier shell 01. When the switch part 02 is pressed, the first sealing bag 03 and the cooling layer 04 are punctured, and the liquid to be vaporized overflows. Under the vacuum state, the boiling point of the liquid becomes lower and it is easy to boil. After boiling, it vaporizes and absorbs heat to cool. The top of the barrier shell 01 releases cold energy to cool the product to be cooled. Among them, the cooling layer 04 is used to conduct the cooling temperature of the liquid in the first sealing bag 03 after vaporization, the water expansion layer 05 is used to accelerate the diffusion area and speed of the liquid, the water blocking sheet 06 is used to block the liquid to prevent over-seepage, the thermal insulation layer 07 is used to maintain the cooling temperature, and the absorption layer 08 is used to absorb the steam after the liquid vaporizes.

[0040] Specifically, the absorbing paper 1 is bonded to the cooling layer 04, and the breathable cotton 3 is bonded to the water-blocking sheet 06. First, the liquid flows out from the middle of the cooling layer 04, and the absorbing paper 1 absorbs moisture and diffuses. Secondly, the liquid is divided into several areas in the vaporization network 2, which reduces the difficulty of liquid vaporization. At the same time, the cold energy generated by the heat absorption of liquid vaporization continues to diffuse around, so that the internal temperature is evenly conducted and distributed. Finally, the unvaporized liquid reaches the breathable cotton 3 for further diffusion. At the same time, the liquid is locked by the breathable cotton 3 and the water-blocking sheet 06. The liquid is vaporized in the vaporization space formed by the absorbing paper 1, the vaporization network 2 and the breathable cotton 3 to achieve refrigeration. It should be noted that the water expansion layer formed by the three-layer structure of the breathable cotton 3, the vaporization network 2 and the breathable cotton 3 can be placed in the refrigeration module in the same way.

[0041] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
