-20°C Thermal Management PCM Is Used In The Transportation Of Goods Where Medicines Need To Be Stored At Low Temperatures

Composition and structure:

• It is generally composed of a phase change core material and a packaging material. The core substances of phase change are usually some substances with a specific phase change temperature of about -20 °C, such as some organic compounds with low melting points (such as some specific fatty acid esters, polyols, etc.) or inorganic compounds (such as some salt hydrates, etc.).
• The encapsulation material is mostly polymer material, which encapsulates the core substance to form a microcapsule-like structure or other packaging form.
• For example, the encapsulation material with a microencapsulated structure forms a strong outer shell on the outside to protect the phase change core material inside from leakage, oxidation or adverse reactions with other external substances, and also facilitates its use and integration in different application scenarios.

Performance Characteristics:

1. Efficient heat storage and release performance

• When the ambient temperature approaches or reaches -20°C, the PCM begins to undergo a phase transition. If the temperature is reduced from above -20°C to -20°C, the PCM will change from one state (such as liquid) to another state (such as solid), and a large amount of latent heat will be released in the process, which can effectively slow down the decline rate of the surrounding environment temperature and maintain a relatively stable temperature environment.
• Conversely, when the temperature rises from below -20°C, the PCM changes from a solid to a liquid state, absorbing heat and preventing the temperature from rising too quickly. For example, in outdoor equipment in some cold regions, the -20°C thermal management PCM can regulate the temperature around the device through a phase change when the temperature changes, protecting the device from extreme temperature changes.

2. Good temperature stability

• During phase transitions around -20°C, the PCM is able to maintain a relatively constant temperature over a relatively narrow temperature range.
• This is critical for applications where temperature stability is critical. For example, in some low-temperature scientific experiments, it is necessary to accurately control the temperature at about -20°C, and PCM can maintain the temperature stability of the experimental environment through phase change to ensure the accuracy and reliability of the experimental results.

3. Strong reusability

• PCM is able to withstand multiple phase change cycles without significant degradation in performance. This means that it can be repeatedly stored and released in different temperature change cycles with good durability.
• For example, in some seasonal cryogenic storage applications, such as frozen food warehouses in winter, the -20°C thermal management PCM can continuously adapt to temperature changes throughout the storage cycle and continue to perform thermal management functions.

4. Adaptability and adjustability

• By selecting different phase change core materials, adjusting their composition ratios, and changing the packaging method, the PCM can be controlled to meet the specific requirements of -20°C thermal management in different application scenarios.
• For example, in different low-temperature transportation processes, according to the characteristics and requirements of the transported goods, suitable -20°C thermal management PCM can be customized to ensure the quality and safety of the goods.

Fields of application:

1. Low temperature refrigeration and transportation

• In the transportation of goods that require cryogenic storage, such as food and medicine, -20°C thermal management PCM can be used as an effective means of temperature control. When the outside temperature fluctuates during transportation, the PCM absorbs or releases heat through phase change, ensuring that the goods are always in a suitable temperature environment of about -20°C, preventing the goods from deteriorating or failing due to temperature changes.
• For example, when transporting frozen vaccines, PCM can maintain a stable low temperature environment to ensure the activity and efficacy of the vaccine.

2. Aerospace field

• In the components of some spacecraft or satellites, it may be necessary to operate at extremely low temperatures and maintain temperature stability. -20°C thermal management PCM can be applied to the thermal control system of these components, under the extreme temperature changes of the space environment, the temperature of the components is regulated by phase change to ensure their normal operation and reliable performance.
• For example, in the electronics bay of some satellites, PCM can prevent damage to electronic components due to too low or too high temperatures.

3. Polar research and exploration equipment

• In scientific research activities and expeditions in the polar regions, various equipment needs to work normally in extremely cold environments. -20°C thermal management PCM can be used to protect equipment, such as in polar weather monitoring equipment, PCM can maintain the temperature stability inside the equipment at extremely low temperatures, ensure the normal operation of sensors and other components, and ensure the accuracy of data collection.
• At the same time, PCM can also be added to the equipment of polar explorers, such as winter suits, sleeping bags, etc., to improve warmth and temperature regulation.

4. Chemical and material processing

• In some chemical production processes, certain raw materials or intermediate products need to be stored or processed at low temperatures of around -20°C.
• -20°C thermal management PCM can be used to construct a thermal control system for cryogenic storage vessels or reaction equipment to maintain the required low temperature environment through phase change to ensure the smooth operation of chemical processes and product quality.
• For example, in some cryogenic synthesis reactions, PCM can help control the reaction temperature and improve the selectivity and yield of the reaction.
