Question: What is radiation heat transfer? Answer: Radiative heat transfer is a mode of heat transfer in which no medium is required; thermal energy is transmitted directly from the heat source in the form of radiation through space, and is absorbed partially or entirely by objects, where it is converted into thermal energy. http://bbs.hcbbs.com/static/image/hrline/4.gif HaiChuan Network’s special May Day event, “Remembering the Glorious Moments,” warmly invites your participation. http://bbs.hcbbs.com/thread-1774529-1-1.html (Source: HaiChuan Chemical Forum) Summary post for HaiChuan Network’s special May Day event, “Remembering the Glorious Moments.” http://bbs.hcbbs.com/thread-1774532-1-1.html (Source: HaiChuan Chemical Forum)
Radiative heat transfer is a process by which heat is transferred between hot and cold objects through electromagnetic wave radiation; it is a form of contactless heat transfer that can also occur in a vacuum
While emitting radiant energy outward, an object also continuously absorbs the radiant energy emitted by other objects around it and converts it back into thermal energy. This process of exchanging radiant energy between objects is known as radiation heat transfer.
Heat transfer in the form of electromagnetic waves is known as radiation heat transfer
Heat is transferred in the form of radiation!

All objects in nature continuously emit radiant energy, while at the same time absorbing radiant energy from other objects and converting it into thermal energy. The overall result of energy being radiated and absorbed between objects is known as radiation heat transfer.
While emitting radiant energy outward, an object also continuously absorbs the radiant energy emitted by other objects around it and converts it back into thermal energy. This process of exchanging radiant energy between objects is known as radiation heat transfer. If radiation heat transfer occurs between two objects at different temperatures, the result is that the hotter object transfers heat to the colder one. If the two objects have the same temperature, then the amount of heat transferred through radiation between them is zero; however, the processes of radiation and absorption between the objects still take place.
