Description

RECYCLABLE COOLING DEVICE}

The disclosure relates to recyclable refrigerants.

Refrigerants are substances used to lower the temperature of objects, for example, PCM (Phase Change Material), ice packs, etc., and they are used in various homes, pharmaceutical transportation, and other industries and applications. PCM is also called a phase change material. When the temperature reaches a certain level, the state changes from solid to liquid, or from liquid to solid. During the state change process, it absorbs or releases heat and can be used to control the temperature of the object. . PCM is used in a variety of fields, including energy storage, building heating and cooling, and electronic equipment cooling. Meanwhile, an ice pack is a refrigerant using ice or frozen gel, and can be mainly used for transport and storage of food or medicine. Ice packs are suitable for products that require cooling at room temperature, and have a slower melting rate compared to ice, providing a longer-lasting cooling effect.

이지만 주변의 기압이 낮아지면 끓는점이 낮아지고, 진공 상태에서의 물은 증발된다. 눈에 보이지는 않지만, 물을 비롯한 액체는 끊임없이 액화 및 기화가 이루어지고 있다. 밀폐된 공간에 물을 두었을 때, 일정 수준에 이르면 액화와 기화가 동적 평형을 이루는데, 이 때의 증기압이 그 온도에서의 포화 수증기압이다. 대기 중에 수분이 전혀 없는 상황이라면 기화에 의해 포화 수증기압에 이를 때까지 물의 양이 감소하게 된다. 대기압이 아닌 매우 낮은 기압에 노출될 경우, 물은 끓는점이 급격하게 낮아져 끓음 현상이 일어나며, 포화 수증기압에 이를 경우 끓음이 멈추게 된다. 이 때 기화된 수증기를 지속적으로 제거해줄 수 있다면 끓음 현상이 유지되어 주변으로부터 기화열을 지속적으로 흡수해 장시간 온도 유지를 할 수 있는 냉매를 제공할 수 있다.Referring to FIGS. 1 to 3, the refrigerant 1 according to one embodiment can be used and recycled without necessarily undergoing a freezing process under specific conditions. For this purpose, the refrigerant 1 can use a technology based on evaporative cooling through vaporized moisture. The boiling point of water at 1 atm is 100.

However, as the surrounding air pressure decreases, the boiling point decreases, and water in a vacuum evaporates. Although it is invisible to the eye, liquids, including water, are constantly being liquefied and vaporized. When water is placed in a closed space, liquefaction and vaporization reach a dynamic equilibrium when it reaches a certain level, and the vapor pressure at this time is the saturated water vapor pressure at that temperature. If there is no moisture in the atmosphere, the amount of water decreases through evaporation until it reaches saturation vapor pressure. When exposed to very low atmospheric pressure other than atmospheric pressure, the boiling point of water drops rapidly, causing boiling, and boiling stops when the saturated vapor pressure is reached. At this time, if the vaporized water vapor can be continuously removed, the boiling phenomenon can be maintained and a refrigerant can be provided that can maintain the temperature for a long time by continuously absorbing heat of vaporization from the surroundings.

The refrigerant 1 may specifically include a container 10 and a lid 20 in order to omit the process of freezing the refrigerant under specific conditions by applying an evaporative cooling method. Lid 20 may be fastened to container 10 via a locking wing, and container 10 may be coupled with lid 20 to provide a seal.

The lid 20 is provided with a vacuum pump connection 21, which can provide a connection to a vacuum pump. The container 10 is combined with the lid 20 and in a sealed state, a vacuum may be created by a vacuum pump. Here, the vacuum pump may be a concept that also encompasses household vacuum equipment (eg, vacuum cleaners, vacuum adsorbers, portable air pumps, etc.).

A liquid supply tank 40 may be disposed within the container 10. The liquid supply tank 40 may supply liquid (eg, water). An open/close cap 42 may be formed on the liquid supply tank 40. The opening/closing cap 42 may be formed to fill the liquid supply tank 40 with liquid from the outside. In some embodiments, liquid supply tank 40 may be disposed on non-absorbent insulation 30.

The oasis 46 may contain a portion of the liquid supplied from the liquid supply tank 40. The oasis 46 may be connected to the liquid supply tank 40 through a liquid transfer tube 44. The oasis 46 may be implemented as a fibrous medium (e.g., non-woven fabric), which slows down the movement speed of the liquid supplied from the liquid supply tank 40 and allows the oasis 46 to It is possible to retain part of the liquid supplied from 40). In some embodiments, the liquid transfer tube 44 may be formed of a non-metallic material such as rubber or plastic.

In some embodiments, liquid transfer tube 44 may be formed from the same fibrous medium as oasis 46. Accordingly, the moving speed of the liquid can be lowered more effectively than when the liquid moving tube 44 is formed of rubber, plastic, etc.

A non-absorbent insulating material 30 may be disposed within the container 10. Specifically, non-absorbent insulation 30 may be arranged to accommodate at least a portion of liquid transfer tube 44 and oasis 46 . That is, the non-absorbent insulation material 30 may have an oasis accommodation space therein so that the oasis 46 can be accommodated and fixed at the same time. The non-absorbent insulating material 30 may be made of a non-absorbent material such as polypropylene so as not to absorb evaporated moisture. The non-absorbent insulating material 30 can block heat exchange due to heat absorption and heat release between the upper and lower parts of the container 10, and can simultaneously provide a passage through which vaporized moisture passes.

A desiccant 32 is disposed on the non-absorbent insulating material 30, so that moisture evaporating from the vaporization initiation cap 48 can reach the desiccant 32 after passing through the non-absorbent insulating material 30. The moisture absorbent 32 may include, for example, silica gel. The moisture absorbent 32 can absorb evaporated moisture. Heat released as the moisture absorbent 32 absorbs moisture may be blocked from reaching the product 50, such as medicine or food, by the non-absorbent insulating material 30. In some embodiments, the desiccant 32 may be disposed at another location within the container 10 that is spaced apart from the non-absorbent insulation 30 or the vaporization initiation cap 48 .

The vaporization start portion 12 is formed on the lower surface of the container 10 and can initiate vaporization of the liquid that has reached the oasis 46. Specifically, the oasis 46 is provided with a vaporization start cap 48, and the vaporization start part 12 is installed in the container 10 so as to be movable upward toward the vaporization start cap 48, as shown in FIG. 2 As described above, as the vaporization initiation portion 12 contacts the vaporization initiation cap 48, the vaporization initiation cap 48 may be broken. When the hole H is created by rupture of the vaporization initiation cap 48, vaporization of the liquid that has reached the oasis 46 through the hole H may be initiated, as shown in FIG. 3 . As evaporation occurs, heat absorption progresses, allowing cooling of the product 50, such as medicine or food, placed at the bottom of the container 10.

Here, the liquid supply tank 40, the liquid transfer tube 44, and the oasis 46 may be implemented to be sealed within the container 10. Before the vaporization start cap 48 is broken, the space of the liquid supply tank 40, the liquid moving tube 44, and the oasis 46 are isolated from the space outside the liquid supply tank 40, and the liquid Vaporization of the liquid present on the moving tube 44 and oasis 46 may not occur. To this end, in some embodiments, when the liquid transfer tube 44 is formed of rubber, plastic, etc., the liquid supply tank 40 and the liquid transfer tube 44 are tightly connected to each other, and the liquid transfer tube 44 If it is formed of the same fiber medium as the oasis 46, a separate case may be formed that is airtightly connected to the liquid supply tank 40 and surrounds the fiber medium. Additionally, since the oasis 46 is also formed of a fibrous medium, a separate case can also be formed that is tightly connected to the liquid transfer tube 44 and surrounds the fibrous medium. That is, before the vaporization initiation cap 48 is broken, liquid exists in the space of the liquid transfer tube 44 and the oasis 46, and the space outside the space may be maintained in a vacuum state. In some embodiments, The vaporization initiation cap 48 may include a rotating portion fixed to the lower surface of the container 10 so that the user can rotate it, and a sharply formed fracture portion capable of breaking the vaporization initiation cap 48, and the rotating portion may include: The fractured portion may be implemented to approach the vaporization initiation cap 48 while the vacuum inside the container 10 is maintained as it rotates.

In some embodiments, the container 10 may be made of a material with high thermal conductivity (eg, aluminum) or a material that can be lightweight (eg, film).

According to this embodiment, the container 10 is maintained in a vacuum state, and the oasis 46 is supplied with liquid from the liquid supply tank 40, and evaporation can occur at a constant slow speed. Until the vaporization start cap 48 is broken, the oasis 46 can hold the liquid supplied from the liquid supply tank 40 and wait. When the vaporization start cap 48 is broken, the vaporization of the liquid that has reached the oasis 46 through the hole H begins, and as vaporization occurs, heat absorption progresses and is placed in the lower part of the container 10. Cooling of the product 50 such as medicine or food may be performed.

The evaporated moisture moves upward in the container 10 and is not absorbed by the non-absorbent insulating material 30 while moving. Moisture that reaches the desiccant 32 disposed at the top of the container 10 is absorbed by the desiccant 32, and the heat released at this time is absorbed by the product 50, such as medicine or food, by the non-absorbent insulating material 30. It is blocked from reaching the area, so it does not affect the cooling effect. Accordingly, the refrigerant 1 can be used without necessarily undergoing a freezing process under specific conditions.

Meanwhile, when the liquid in the liquid supply tank 40 is depleted, the moisture absorption function of the moisture absorbent 32 is reduced, or vaporization is complete, the user can open the lid 20 and replace or initialize the contents. For example, the user may refill liquid into the liquid supply tank 40 through the opening/closing cap 42, replace the vaporization initiation cap 48 with a new, unbroken one, or bake the desiccant 32 in an oven. After taking measures such as removing moisture to replace the contents and closing the lid 20, a vacuum can be created inside the container 10 through the vacuum pump connection 21. In this way, users can easily recycle it.
