Abstract
In the present invention, a stable heat generation unit which can stably absorb stress and diffuse heat even in thermal stress is constructed by providing a locking through hole 2p in an end portion of a heat generator 2 in a heat generation unit, and engaging a fixed portion 5 with through holes respectively formed in a first holding portion 3a and a second holding portion 3a constructing a holder 3 holding the end portion of the heat generator 2 so as to hold the end portion of the heat generator 2, and a heating apparatus is constructed by the heat generation unit.
Claims51
A heat generation unit comprising:
- a heat generator having a heat generating portion;
- a holder attached to an end portion of the heat generator;
- a lead wire electrically connected to the holder so as to supply power from outside to the heat generator;
- and
- the heat generator, the holder and the lead wire being arranged within a container,
- wherein the holder has a first holding portion and a second holding portion which are arranged so as to be opposed to each other, through holes are respectively formed in the first holding portion and the second holding portion, and center axes of the through holes are arranged coaxially,
- wherein an end portion of the heat generator has a locking through hole, and is arranged between the first holding portion and the second holding portion, whereby the locking through hole is arranged on the same axis as the center axes,
- wherein a fixed portion having an engagement portion engaging with each of the through holes of the first holding portion and the second holding portion and the locking through hole in the end portion of the heat generator is provided, and
- wherein the fixed portion has a first position regulating member for regulating a position of the first holding portion in one end side of the engagement portion arranged in an outer side surface of the first holding portion in which the end portion of the heat generator is not arranged, and a second position regulating member for regulating a position of the second holding portion in the other end side of the engagement portion arranged in an outer side surface of the second holding portion in which the end portion of the heat generator is not arranged, and is structured such that the end portion of the heat generator is held by the first holding portion and the second holding portion.

A heat generation unit comprising:
- a band-like heat generator formed as a film sheet by a material including a carbon-based substance, and having a two-dimensional isotropic thermal conductivity;
- a power supply portion having a holder including a first holding portion and a second holding portion arranged so as to be opposed while having a contact surface holding both ends of the heat generator and formed by a conductive material, and a lead wire electrically connected to the holder, the lead wire having a retainer portion formed in the power supply portion, and supplying power to the both opposed ends in the heat generator;
- and
- a container internally including the heat generator and a part of the power supply portion,
- wherein the end portion of the heat generator is disposed between the first holding portion and the second holding portion, and a retainer receiving portion formed in the end of the heat generator is engaged with the retainer portion together with the first holding portion and the second holding portion.

A heat generation unit comprising:
- a band-like heat generator formed in a film sheet shape in which a thickness is equal to or less than 300 μm, as a film sheet by a material including a carbon-based substance, and having a two-dimensional isotropic thermal conductivity;
- a power supply portion supplying power to the both opposed ends in the heat generator;
- and
- a container internally including the heat generator and a part of the power supply portion, and being filled with an inert gas so as to be sealed in the power supply portion,
- wherein a position regulating portion is firmly attached to the power supply portion in an inner portion of the container and holds the heat generator at a predetermined position in the inner portion of the container, and a current path in the power supply portion is prevented from being formed in the position regulating portion.
