The present disclosure relates to an incubator with a sustained release layer, which can be used for food transport, drug cold chain transport and fresh food delivery. For convenience of description, the incubator with the sustained-release layer according to the present disclosure may be simply referred to as an incubator. In some examples, an incubator with a slow release layer may also be referred to as an incubator.
Hereinafter, the incubator according to the present embodiment will be described in detail with reference to the drawings.
Fig. 1 is an overall view showing an incubator 1 having a sustained-release layer according to an example of the present disclosure.
Referring to fig. 1, in some examples, an incubator 1 includes an outer case 10, and an inner case 20 disposed inside the outer case 10. The inner case 20 has a receiving chamber 21 for receiving articles. The inner case 20 includes a heat storage layer 22, a slow release layer 23, and a constant temperature layer 24 sequentially arranged from the outer case 10 to the housing chamber 21.
In the incubator 1 having the sustained-release layer 23 according to the present disclosure, in some examples, the heat storage layer 22 may release heat or cold, and the constant-temperature layer 24 may absorb the heat or cold released from the heat storage layer 22 and convert it into latent heat and release it slowly to extend the incubation time, during which the temperature of the constant-temperature layer 24 does not change to bring the temperature in the accommodation chamber 21 within a predetermined range. Thereby, the contents of the receiving chamber 21 are at a suitable storage temperature.
In some examples, the slow release layer 23 may reduce the speed at which the thermal storage layer 22 releases heat or cold to the constant temperature layer 24, thereby enabling effective regulation of the temperature of the accommodating chamber 21.
In some examples, the material of the outer case 10 may include a waterproof material. In some examples, the material of the outer case 10 may include cloth. In some examples, the outer case 10 may include oxford or canvas. Therefore, the box body has the effects of beauty and water resistance.
In some examples, the material of the outer case 10 may include insulation. In some examples, the outer case 10 may include foamed polyurethane, polystyrene foam, foamed polyethylene, vacuum insulation panels, or rubber-like foams. In this case, the outer case 10 can have an insulating effect.
In some examples, the outer case 10 may have a rectangular parallelepiped shape, a square shape, or a cylindrical shape. In some examples, the inner case 20 may have a rectangular parallelepiped shape, a square shape, or a cylindrical shape.
In some examples, the incubator 1 further includes an insulation layer (not shown) disposed between the outer case 10 and the inner case 20. The isolation layer is used to isolate the heat exchange between the inner box 20 and the external environment. This reduces the heat or cold loss of the heat storage layer 22, and can prolong the heat retention time or improve the heat retention efficiency.
In some examples, the insulation may be disposed on the inner wall of the outer casing 10. For example, the insulating layer may be bonded to the outer case 10. In some examples, the insulation layer may be integrally formed with the inner case 20. For example, the barrier layer may be integrally formed with the sustained release layer 23. For example, one or more cavities are formed between the isolation layer and the sustained release layer 23, and a constant temperature layer 24 can be arranged in each cavity.
In some examples, the insulating layer may include an insulating material. In some examples, the insulation layer may include foamed polyurethane, polystyrene foam, foamed polyethylene, vacuum insulation panels, or rubber-like foams. The isolation layer may be multi-layered in some examples. For example, a three-layer structure of styrofoam-air-styrofoam may be used.
In some examples, the incubator 1 further includes a cover 30, and the cover 30 covers the inner case 20 to close the accommodation chamber 21. In some examples, the cover 30 may cover the inner case 20 to enclose the accommodating cavity 21, and an enclosed area between the constant temperature layer 24 and the cover 30 is the accommodating cavity 21. This enables the housing chamber 21 in the incubator 1 to be separated from the external environment.
In some examples, the cover 30 may be integrally formed with the outer case 10. For example, the outer case 10 and the cover 30 are integrally formed of oxford cloth or canvas. In some examples, the cover 30 is detachably provided to the outer case 10. In some examples, the cover 30 is hinged to the outer case 10.
In some examples, the cover 30 may include insulation. In this case, the heat exchange of the housing chamber 21 with the external environment can be reduced. For example, the cover 30 may include foamed polyurethane, polystyrene foam, foamed polyethylene, vacuum insulation panels, or rubber-like foam. Specifically, the cover 30 may have a structure in which a foamed polyurethane sheet is bonded to oxford cloth.
Referring to fig. 2 in conjunction, fig. 2 is a plan view illustrating an inner case 20 according to an example of the present disclosure.
Referring to fig. 2, in some examples, the inner case 20 may include: an accommodating cavity 21, and a heat storage layer 22, a slow release layer 23 and a constant temperature layer 24 which are arranged in sequence from the outer box body 10 to the accommodating cavity 21.
In some examples, the inner case 20 may have a three-layer structure. The outer layer of the inner box body 20 is a heat storage layer 22, the inner layer of the inner box body 20 is a constant temperature layer 24, and a closed area between the constant temperature layer 24 and the box cover 30 is a containing cavity 21. This makes it possible to provide the inner case 20 having a simple structure.
In some examples, the inner box 20 may be a four-layer structure. For example, a damping layer can be arranged within thermostatic layer 24.
In some examples, the thermal storage layer 22 may be a box structure (for convenience of description, hereinafter referred to as a box shape) composed of end-to-end side walls and a bottom surface. In some examples, thermostatic layer 24 is box-shaped. In some examples, the slow release layer 23 is box-shaped. In some examples, the box structure may be rectangular parallelepiped or cylindrical. In some examples, the thermal storage layer 22 may be a frame of end-to-end sidewalls (for convenience of description, hereinafter referred to as a frame). In some examples, the sustained release layer 23 may be frame-shaped. In some examples, the thermostatic layer 24 may be frame-shaped.
In some examples, thermostatic layer 24 and sustained release layer 23 may be shaped differently. In some examples, the constant temperature layer 24 and the heat storage layer 22 may be different in shape. In some examples, the sustained release layer 23 and the thermal storage layer 22 may be different in shape. For example, in some examples, the thermal storage layer 22 may have a frame shape, the constant temperature layer 24 may have a cylindrical shape, and the sustained release layer 23 may have a transitional shape, that is, the sustained release layer 23 has a rectangular parallelepiped shape in outline, and may be disposed in the thermal storage layer 22 while having a cylindrical cavity for accommodating the constant temperature layer 24.
In some examples, the thermal storage layer 22 may completely cover an outer region of the sustained release layer 23. In some examples, the thermal storage layer 22 is composed of several sections, and the sections are not in contact with each other. For example, the thermal storage layer 22 may include a plurality of ice rows arranged independently of each other, and may be disposed on the outer periphery of the sustained release layer 23 by means of an ice row holder or a partition, etc.
In some examples, thermal storage layer 22 is at a different temperature than thermostatic layer 24. In some examples, the temperature of the thermal storage layer 22 may be lower than the temperature of the constant temperature layer 24. In some examples, the thermal storage layer 22 includes ice banks. In some examples, the thermal storage layer 22 may include dry ice. In some examples, the thermal storage layer 22 may include a heat sink system. This enables the heat storage layer 22 to supply cooling energy.
Fig. 5 is a schematic diagram illustrating an ice bank according to an example of the present disclosure.
In some examples, the ice bank is a split ice bank 221. Thereby, the weight of the individual ice row can be reduced, and it is easy to prepare, transport and replace.
In some examples, the ice bank may also be a monolithic ice bank.
In some examples, the surface of the ice bank adjacent to the slow release layer 23 has a recess. In some examples, the surface of the split ice bank 221 near the slow release layer 23 has a recess 2211. In some examples, the shape of the recess 2211 can be curved. In some examples, the shape of the recess 2211 can be pyramid-shaped. This increases the specific surface area of the ice bank, and can improve the efficiency of the ice bank in providing cooling energy.
In some examples, the split ice bank 221 may have a substantially rectangular parallelepiped shape or a quadrangular prism shape, and a cross-section of a right trapezoid shape. In some examples, the angle between the hypotenuse and the base of the right trapezoid can be 45 °. In this case, the assembly and arrangement of the split ice bank 221 are facilitated.
Fig. 6 is a schematic diagram showing the arrangement of ice rows in the heat-insulating box 1 according to the example of the present disclosure.
Referring to fig. 6, in some examples, the split ice rows 221 may be arranged in contact with each other. In some examples, the split ice bank 221 may be quadrangular prism shaped. In some examples, the cross-section of the quadrangular prism may be a right-angled trapezoid. In some examples, the angle between the hypotenuse and the base of the right trapezoid can be 45 °. In some examples, two identical split ice rows 221 may be contacted by the plane of the right-angled edge to achieve a stable arrangement of the ice rows on the same plane. In some examples, two identical split ice rows 221 may achieve a stable vertical arrangement of the two ice rows by the face contact of the beveled edges. In some examples, the split ice bank 221 may include multiple specifications, such as the height of the right trapezoid cross section of the split ice bank 221, the length of the base, and the angle between the oblique side and the base may be multiple specifications. In this case, the split ice rows 221 may be arranged in various patterns. In some examples, the split ice bank 221 may also be rectangular parallelepiped shaped.
In some examples, the split ice rows 221 may be non-contacting with each other, such as by a structure such as a cage, where the split ice rows 221 are not in contact with each other and are arranged in a prescribed pattern. That is, in some examples described above, the thermal storage layer 22 is composed of several sections, and the sections are not in contact with each other. For example, the thermal storage layer 22 may include a plurality of ice rows arranged independently of each other, and may be disposed on the outer periphery of the sustained release layer 23 by means of an ice row holder or a partition, etc.
In some examples, the temperature of the thermal storage layer 22 may be higher than the temperature of the constant temperature layer 24. In some examples, the thermal storage layer 22 may include a resistive wire. In this case, the resistance wire of the thermal storage layer 22 may be part of the heat source system. Thus, the thermal storage layer 22 may provide heat.
In some examples, the slow release layer 23 may include a first slow release region 231 having a first heat transfer coefficient and a second slow release region 232 having a second heat transfer coefficient, wherein the first heat transfer coefficient is different from the second heat transfer coefficient. In this case, it is possible to prevent the heat or cold of the heat storage layer 22 from being transmitted to the constant temperature layer 24 all at once, thereby slowing down the rate at which the heat storage layer 22 and the constant temperature layer 24 transfer heat.
In some examples, thermostatic layer 24 is made of a composite material composed of a phase change material and an insulating material. In some examples the insulation may comprise foamed polyurethane, polystyrene foam, foamed polyethylene, vacuum insulation panels, or rubber-like foams. In some examples, the phase change material may be a phase change material. In some examples, the phase change material may be an organic-based phase change material, a molten salt-based phase change material, or a composite-based phase change material.
In some examples, the temperature of the phase change material is determined according to the storage condition of the article stored in the accommodation chamber 21. In some examples, the phase change material may be a phase change material at 5 ℃, 28 ℃, or-2 ℃. For example, the contents of the chamber 21 may require storage conditions of 0 to 10 c, and a 5 c phase change material may be selected.
In some examples, the constant temperature layer 24 may control the temperature of the accommodating chamber 21 within a predetermined range. In some examples, the predetermined range may be 0 ℃ to 10 ℃. In some examples, the predetermined range may be 25 ℃ to 32 ℃. In some examples, the predetermined range may be-5 ℃ to 1 ℃.
In some examples, thermostatic layer 24 may be removable. In this case, it is convenient to replace thermostatic layer 24 in the event of a failure, or to use thermostatic layer 24 of a different material to adapt to the conditions of the different articles stored in housing chamber 21. In some examples, thermostatic layer 24 and sustained release layer 23 may be bonded together. In some examples, the material of second sustained release region 232 may be the same as the material of constant temperature layer 24. In some examples, second extended release area 232 is integrally formed with thermostatic layer 24.
In some examples, the slow release layer 23 includes a first slow release region 231 having a first heat transfer coefficient and a second slow release region 232 having a second heat transfer coefficient. Wherein the first heat transfer coefficient is different from the second heat transfer coefficient. In this case, it is possible to prevent the heat or cold of the heat storage layer 22 from being transmitted to the constant temperature layer 24 all at once.
Fig. 4 is a structural view showing the sustained-release layer 23 according to an example of the present disclosure.
Referring to fig. 4, in some examples, the first sustained release region 231 may have a plate shape. In some examples, the material of first sustained release region 231 may include an insulating material. For example, the material of the first slow release region 231 may be foamed polyurethane, polystyrene foam, foamed polyethylene, vacuum insulation panel, or rubber-based foam.
In some examples, the second sustained release region 232 may be porous. In some examples, the second extended release area 232 may include air. In some examples, the material of the second sustained release region 232 may include a phase change material. In some examples, the material of second sustained release region 232 may be the same as the material of constant temperature layer 24.
In some examples, the sustained release layer 23 may be a tiled structure. For example, in some examples, the slow release layer 23 may be a box structure formed by splicing 4 or 5 polystyrene foam plates with through holes. In some examples, the number of vias may be 1. In some examples, the number of vias may be multiple.
In some examples, the sustained-release layer 23 may have a similar shape to the temperature storage layer 22, for example, the sustained-release layer 23 and the temperature storage layer 22 have a box shape, or the sustained-release layer 23 and the temperature storage layer 22 have a frame shape. In some examples, the thermal storage layer 22 and the sustained release layer 23 may be shaped differently. For example, the thermal storage layer 22 may have a frame structure, and the sustained-release layer 23 may have a box shape.
In some examples, the sustained-release layer 23 may prevent the thermal storage layer 22 from contacting the constant-temperature layer 24. In some examples, the contact area of the thermal storage layer 22 with the constant temperature layer 24 may be smaller than the area of the constant temperature layer 24 near (i.e., outside) the sustained release layer 23. In this case, it is possible to avoid the heat storage layer 22 from releasing excessive heat to the constant temperature layer 24 in a short time or the heat storage layer 22 from absorbing excessive heat from the constant temperature layer 24 in a short time.
Fig. 3 is a schematic view showing heat or cold transfer of the inner case 20 according to the example of the present disclosure.
In some examples, the heat exchange between thermal storage layer 22 and thermostatic layer 24 may include at least one of thermal conduction, thermal convection, or thermal radiation.
Referring to fig. 3, in some examples, the thermal storage layer 22 may absorb heat from the constant temperature layer 24, the constant temperature layer 24 releases latent heat and keeps the temperature constant to maintain the temperature of the accommodating chamber 21 within a predetermined range, and the slow release layer 23 serves to reduce the rate at which the thermal storage layer 22 absorbs heat from the constant temperature layer 24. In other examples, the heat storage layer 22 releases heat, the constant temperature layer 24 absorbs the heat released from the heat storage layer 22 to store in latent heat and keep the temperature constant to maintain the temperature of the accommodating chamber 21 within a predetermined range, and the slow release layer 23 serves to reduce the rate at which the constant temperature layer 24 absorbs heat to the heat storage layer 22. That is, the heat flux density at the interface of the constant temperature layer 24 during the heat exchange process can be reduced, and the failure or malfunction of the constant temperature layer 24 can be effectively avoided.
While the present disclosure has been described in detail in connection with the drawings and examples, it should be understood that the above description is not intended to limit the disclosure in any way. Those skilled in the art can make modifications and variations to the present disclosure as needed without departing from the true spirit and scope of the disclosure, which fall within the scope of the disclosure.
