A Cooling Element is a type of thermal transport package that has a shape-retaining outer surface and can maintain its form when the temperature changes. norcold refrigerator parts This is an essential requirement for the safe transportation of sensitive goods.
Various different types of cooling elements are available and can be used in many different applications. They can be made of foam, phase change material (PCM), or a combination of materials such as metals and plastics.
These elements are ideal for use in the medical sector and can be used to transport things such as breast milk, which needs to stay at a constant temperature throughout the entire process. The elements also work well in compact spaces and are easy to carry and store.
They are strong and durable, ensuring that they will be suitable for repeated use. This makes them the preferred solution for transports that must be returned.
In contrast to gel packs and other flexible packaging, shape-retaining chilled elements retain their shape both when frozen and in unfrozen condition. This allows them to be transported at extremely high temperatures while maintaining their shape.
These elements can be inserted into bottle holders, bags or other packaging to maintain the temperature of the product inside. They are usually used to transport goods at temperatures of 2 degrees or less, but can also be adapted for other temperature ranges, such as -21 to +20 degrees Celsius.
Thermoelectric coolers are often used in scientific devices and for laboratory equipment to control temperature. They are based on the Peltier effect, which consists of an array of alternating n- and p-type semiconductors that act as a solid-state heat pump. These semiconductors can be made of bismuth telluride, antimony telluride or other metals and alloys.
One aspect of this technology is that the working elements can be isolated from each other and in a sealed casing. This is particularly desirable for cooling elements that must be used in very harsh environments or where absolute energy efficiency is not a primary concern.
For example, they can be used in stationary furnaces to protect the refractory material from excessive temperatures and corrosive media. They also work effectively in a wide range of process conditions, such as during the heating and cooling of liquids and gases.
Another aspect of this technology is that it can be manufactured in a more flexible manner. This means that the intermediate layer does not need to be brought into the desired fitting shape beforehand and welded together. This saves time and cost, but also reduces manufacturing complexity.
This is especially true in applications where the element is exposed to abrasion and wear, such as in the medical field or in sports. In such cases, it is particularly important to ensure that the cooling element can withstand repeated use.
Thermoelectric coolers can be fabricated from a variety of materials, but the most commonly used are bismuth telluride, antimony telling and lead telling. Newer high-performance materials for thermoelectric cooling are actively researched and being developed.
