Abstract
A refractory block design for re-radiating a substantial amount of heat losses back to a heated product thereby substantially maintaining its required temperature. A relatively thin sheet of stainless steel, i.e. the ratio of the thickness of the sheet being approximately 1/500th of the thickness of the heated product, is wrapped in a sinuous manner around one side of a refractory fiber block arranged in a similar sinuous manner to tightly fit into the folds of the block for storing heat, and radiating heat back to the heated product when thermal equilibrium therebetween is reached.
Claims12
A heat shield for re-radiating heat, comprising:
- thermal insulating material means having a number of closely adjacent co-extending sections provided with one or more holding surfaces formed by said adjacent sections, and
- thermal absorbing material means having a fast heat up characteristic and having a portion directly exposable to a heat source,
- said thermal absorbing material means also including for said exposable surface a substantially co-extending non-exposable surface,
- said exposable and non-exposable surfaces of said thermal absorbing material means arranged to form a closely adjacent receptacle for receiving a different one of said co-extending sections of said thermal insulating material means,
- said thermal absorbing material means being in the form of a flat sheet-like material having a thickness that requires assistance to hold a predetermined operative shape for said exposable surfaces,
- said assistance consisting of the predetermined form being such that it takes a shape which will give inherent support to the exposable surfaces,
- wherein said non-exposable surfaces of said thermal absorbing material means has contacting surfaces for supporting associated exposable surfaces, and further wherein said thermal insulating material means has a supporting relationship with an adjacent portion of said exposable surfaces of said thermal absorbing material means.

A heat shield for re-radiating heat comprising:
- thermal insulating material having a number of closely adjacent co-extending sections provided with one or more holding surfaces formed by said adjacent sections, and
- thermal absorbing material having a fast heat up characteristic and having a portion directly exposable to a heat source which portion includes a series of relatively short co-extending surfaces,
- said thermal absorbing material also including for each said short surface a substantially co-extending longer surface arranged not to be directly exposed to said heat source,
- said longer surfaces of said thermal absorbing material arranged to enwrap at least a portion of a different one of said co-extending sections of said thermal insulating material and restrained by said holding surfaces of two adjacent sections of said insulating material,
- wherein the nature and thermal mass of said thermal absorbing material and the nature and relationship of said thermal insulating material relative thereto greatly increases the re-radiating thermal characteristics of said thermal absorbing material.

A heat shield for re-radiating heat, comprising:
- a sheet of insulating fabric folded in a sinuous manner to create a plurality of folds of adjacent layers of fiber insulating material,
- said adjacent layers of said insulating material constructed and arranged relative to their adjacent fold to closely bind said layers together into a panel, and
- a continuous sheet of ferrous material having heat absorbing characteristics arranged at least along and against one outer surface of said sheet of insulating fabric in a corresponding sinuous manner such that portions of said ferrous material enwrap exposed areas of said folds of said insulating fabric and portions of said ferrous material fit tightly into said adjacent folds of said insulating fabric so as to be supported therein,
- said ferrous material having a thickness such that said enwrapping of said ferrous material requires assistance to hold a predetermined operative shape, said assistance consisting of a predetermined form being such that it takes a shape which will give inherent support to said enwrapped ferrous material,
- said exposed areas of said folds of said insulating fabric enwrapped by said ferrous material being exposed to a heat source in a manner said heat from said source is absorbed in said exposed areas of said folds and conducted and stored in said portions of said adjacent folds to quickly approach thermal equilibrium between said ferrous material and said heat source to re-radiate heat back to said heat source to maintain said heat source at a predetermined termperature.
