Just wondering if there are substances (even just theoretical ones) able to conduct heat without heating up itself. How does that operate? What properties are different from that of ordinary substances?

Special heat conduction refers to the transfer of thermal energy through a material or between materials that have unique properties or conditions. This can include materials with high conductivity, insulating materials, or materials with varying temperatures.
Regular heat conduction occurs when there is a temperature difference between two materials, causing thermal energy to transfer from the hotter material to the cooler material. Special heat conduction involves unique circumstances, such as varying temperatures or materials with high or low conductivity, that can affect the rate or direction of heat transfer.
Some examples of special heat conduction include the transfer of heat through a vacuum, known as radiation, which is different from regular heat conduction through direct contact. Another example is heat transfer through a material with high conductivity, such as copper, which is used in many electronic devices.
Special heat conduction plays a crucial role in many everyday activities, such as cooking, heating and cooling systems, and transportation. For example, the use of insulating materials in homes can help regulate the temperature inside, while the use of conductive materials in cooking utensils allows for efficient heat transfer.
Understanding special heat conduction is essential in various fields, including engineering, materials science, and thermodynamics. It allows for the development of more efficient heating and cooling systems, improved insulation materials, and better understanding of heat transfer in various environments and scenarios.
