Abstract

PURPOSE:To concentrate the radiation heat in one direction by integrally fixing graphite heating fibers on a metal plate via a heat-resistant adhesive having an electric insulation resistance property. CONSTITUTION:A graphite heating fiber raw material 2 is fixed on one face of a metal plate 1 via an adhesive 3. The heat radiated from both faces of the heating raw material 2 is reflected on one face of the metal plate l, the heat quantity is large, and the efficiency is improved. When the metal plate is formed into a curved surface shape, the heat quantity can be concentrated at the position of the focal point. When a silicone adhesive is used for the adhesive 3, it has a high electric resistance value (about 100KOMEGA or above), the heat resistance (about 300 deg.C or above), and good heat conductivity, and it is not broken easily.

Description

Detailed Description of the Invention

[0000]

[Industrial application] The present invention relates to a fiber heating material.

[0002]

2. Description of the Related Art Many conventional fiber-based heat-generating materials are covered on both sides with a flexible synthetic resin-based material or metal foil.

[0003]

Therefore, it is necessary to concentrate the heat radiated from both sides of the fiber heating material in one direction.

[0004]

To solve the problems, a graphite-based heat-generating fiber material is fixed on one surface of a metal plate having an arbitrary shape through an adhesive having electrical resistance so as to be integrated.

[0005]

[Function] Therefore, the radiant heat from the graphite heat generating fiber material is radiated in one direction, and if the metal plate is made into a curved surface with the graphite heat generating fiber material as the inner surface, it is radiated to the focal point of the curved surface. The heat is concentrated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a fiber heat generating material with a reflection plate in which a graphite heat generating fiber material 2 is fixed on one surface of a metal plate 1 with an adhesive 3. FIG. 2 shows an embodiment of a fiber heating material with a reflection plate in which the metal plate 1 is formed into a curved shape with the graphite-based heating fiber material 2 as the inner surface. FIG. 3 shows an embodiment of a fiber heating material with a reflecting plate, in which a graphite-based heating fiber material 2 is fixed to the inner surface of the metal plate 1 having a parabolic reflection shape. That is, by fixing the graphite-based heating fiber material 2 on one side of the metal plate 1, since the heat generated from both sides of the graphite heating fiber material 2 is reflected on one side of the metal plate 1, the amount of heat generated is large and the efficiency is high. Become good. Therefore, if the calorific value is the same as when the metal plate 1 is not provided, the electric power applied to the graphite heat generating fiber material 2 can be reduced. Further, as shown in FIG. 2, if the metal plate 1 is curved, there is an advantage that the amount of heat is concentrated at the position of the focal point F as compared with other positions. That is, the total calorific value = fiber calorific value · (d1 · d2) with the calorific value proportional to the curved area (d1 · d2). Further, as shown in FIG. 3, if the metal plate 1 is formed into a parabolic shape and the graphite-based heat generating fiber material 2 is fixed to the inner surface thereof, one point of the focal point F of the parabola concentrates heat from the other surface, and the total heat generation amount. Becomes larger in proportion to the parabola diameter D.
That is, since it depends on the total calorific value = fiber calorific value · D, the calorific value of the focus F is D times the calorific value of the graphite-based heat generating fiber material 2. In addition, graphite-based heating fiber material 2
Is fixed to the metal plate 1 with the adhesive 3, so that it is not easily damaged as in the conventional fiber heating material having flexibility. The adhesive 3 has a high electrical resistance value (about 10
Since there is used a silicon-based adhesive having a heat resistance (about 300 ° C. or more) and a good thermal conductivity, it has no problem.
