Description

Modular connection structure of refrigerant pack {MODULAR CONNECTING STRUCTURE OF THE REFRIGERANT PACK}

The present invention relates to a modular connection structure for refrigerant packs, and more specifically, to a modular connection structure that can connect two or more refrigerant packs as a group while spaced apart from each other at a certain distance.

The cold chain system refers to a system that ensures the quality and safety of products by maintaining low temperatures throughout the distribution process of products that require temperature control, such as agricultural and livestock products, foodstuffs, and pharmaceuticals, as their quality can vary depending on temperature. The cold chain system was first commercialized in the 1940s, and continues to develop to this day as national income increases, consumers' demand for fresh food increases, and the need for cold chain gradually increases.

In particular, pharmaceuticals must be stored and transported within a specific temperature range to ensure efficacy and stability, so maintaining an appropriate temperature is very important. Medicines such as vaccines are especially vital to life, so temperature control is essential during the distribution process.

According to these needs, various cold storage devices (or cold storage containers) are being developed to increase economic efficiency and ease of use so that objects can be efficiently cooled and transported easily. In general, storage devices for cold storage are implemented and utilized by storing objects in containers made of materials such as Styrofoam or plastic, placing refrigerant packs filled with refrigerant inside, packaging them, and transporting them.

A phase change material (PCM) may be used as a refrigerant in a refrigerant pack. A phase change material (PCM) is a special material that converts from a liquid to a solid or from a solid to a liquid at a specific 'phase change temperature'. You can. Refrigerant packs using PCM as the refrigerant can be reused, and after checking for physical damage or refrigerant leaks, the used refrigerant pack can be re-frozen by placing it in a freezer or special refrigeration device.

When refreezing refrigerant packs, it may be important to ensure sufficient space between refrigerant packs. This is to allow the cooling air to effectively cool the entire refrigerant pack. If refrigerant packs are directly stacked or covered, the overlapping refrigerant packs may not be cooled properly as the contact surface with the outside is reduced. Therefore, conventionally, a plurality of refrigerant packs are placed side by side in a special refrigeration device, or are arranged using trays or shelves that allow air flow between the refrigerant packs.

However, there are several problems that arise when using trays to refreeze refrigerant packs. For example, using trays or special refrigeration units may make it difficult to utilize the space inside them as efficiently as possible. In addition, additional costs arise from having to produce additional trays, and the trays themselves also require additional management, such as regular cleaning and disinfection.

For example, the refrigerant may be tetradecane, but is not limited thereto.

The refrigerant pack unit 1150 may include a plurality of sub-refrigerant packs. In a specific embodiment, the refrigerant pack unit 1150 may be composed of six sub-refrigerant packs so that all surfaces of the hexahedral-shaped internal body unit 1130 can be externally surrounded. As shown in FIG. 9, the refrigerant pack unit 1150 includes one first sub-refrigerant pack 1150a provided in the upper direction of the inner body 1130 and four provided in the side direction of the inner body 1130. It may include two second sub-refrigerant packs (1150b) and one third sub-refrigerant pack (1150c) provided in the lower direction of the inner body portion (1130). The first sub-refrigerant pack (1150a) is provided toward the top of the inner body portion (1130) and may be provided in contact with the bottom of the cover portion (1160). The second sub-refrigerant pack (1150b) is provided to surround the side exterior of the inner body portion (1130) and may be disposed between the inner body portion (1130) and the inner housing (1120). The third sub-refrigerant pack 1150c is disposed on the lower surface of the inner body portion 1130 and may be disposed between the inner body portion 1130 and the inner housing. As each sub-refrigerant pack is provided to surround the inner body portion 1130, objects stored inside the inner body portion 1130 can be maintained at a specific temperature.

As shown in FIG. 9, each sub-refrigerant pack unit corresponding to the first sub-refrigerant pack (1150a) and the second sub-refrigerant pack (1150b) has an inclined surface (for example, the inclined surface 204 in FIG. 1). can be contacted through Since each sub-refrigerant pack is provided in contact through contact between inclined surfaces, the contact area between each sub-refrigerant pack can be increased. For example, when each sub-refrigerant pack is provided in contact without an inclined surface, the contact area between the sub-refrigerant packs is small, and active heat exchange with the outside occurs corresponding to the contact portion. This may prevent the object from being maintained at an appropriate temperature, thereby reducing storage and transport efficiency of the object. In the present invention, by ensuring that each of the plurality of sub-refrigerant packs includes an inclined surface 1156, the influence of external temperature can be minimized and objects stored inside can be maintained at a more appropriate temperature.
