Abstract

PROBLEM TO BE SOLVED: To provide a portable heater and warmer having its own heat source by bonding a heat insulating sheet formed of a heat insulating fiber to a heating sheet formed of a heat conductive fiber, and arranging a heating part for heating a heat medium and a pump device for circulating the heat medium in a part of the heating sheet. SOLUTION: When a heating part 4 such as catalyst burning device using benzine as fuel is heated, a heat medium 5 is circulated in a circulating passage 3 by pumping action of a pump device 6 such as heat driving pump to which evaporation and condensation of the heat medium 5 is applied. By this circulation, heat possessed by the heat medium 5 is transmitted from a wall surface of the circulating passage 3 to the whole surface of a heating sheet 1 formed of a heat conductive fiber. Since a heat insulating sheet 2 is stuck to the reverse side of the heating sheet 1, the heat transmitted to the heating sheet 1 is prevented from being diffused, and the heat generated from the heating part 4 can be efficiently utilized for heating and warming. As the heat medium 5, water or a mixture in which 35% alcohol is mixed to water is used.

【Example】

(Embodiment 1) A first embodiment of the heating / warming device of the present invention will be described below. FIG. 1 is a sectional view showing the structure of this embodiment. A heat insulating sheet 2 made of heat insulating fibers is bonded to the back surface of the heating sheet 1 made of heat conducting fibers.
As the heat-conducting fibers constituting the heating sheet 1, those in which metal particle layers dispersed in a flexible synthetic resin binder are formed around a yarn made of natural fibers or synthetic fibers, or aluminum-plated for good heat diffusion A glass fiber knitted or a metal fiber can be used. Further, as the heat insulating fibers constituting the heat insulating sheet 2, for example, fibers such as glass fiber, cotton and wool can be used. On the surface of the heating sheet 1, a tube-shaped or bag-shaped circulation path 3 is attached. A casing 7 that holds the heat generating portion 4 and the pump device 6 is attached to one end of the heating sheet 1 and the heat insulating sheet 2.
The heat generating part 4 communicates with the circulation path 3 and heats the heat medium 5 enclosed in the circulation path 3. As the heat generating part 4, a catalytic combustion device using benzine, butane gas or the like as fuel can be considered.

The operation of this embodiment will be described below. When the heat generating part 4 is caused to generate heat, the heat medium 5 circulates in the circulation path 3 by the pumping action of the pump device 6. By this circulation, the heat of the heat medium 5 is transferred from the wall surface of the circulation path 3 to the heating sheet 1. Since the heating sheet 1 is composed of heat conductive fibers, the heat of the heating medium 5 is efficiently transferred to the entire surface of the heating sheet 1. Since the heat insulating sheet 2 is attached to the back surface of the heating sheet 1, the heat transferred to the heating sheet 1 is prevented from being dissipated and kept warm.
That is, the heat generated by the heat generating portion 4 is efficiently used for heating and heat retention.

At this time, in this embodiment, as the heat medium 5, water or a mixture of water and 35% alcohol is used. The mixed solution has the property of not freezing even in extremely cold regions. Particularly, in the case of a mixed liquid prepared by mixing 35% alcohol with water, it does not freeze even in an extremely cold region of -20 ° C. Further, when the alcohol concentration is made higher than 35%, the latent heat becomes low and the thermal efficiency for heating the heating sheet 1 is lowered. Therefore, increase the alcohol concentration to 3
5% is optimal for use in such an extremely cold region. The mixed solution of water and alcohol is not separated because water and alcohol are azeotropically distilled.

Since the cushioning material has a heat insulating effect, according to this embodiment, it is possible to realize a heating / warming device having a particularly good heat insulating effect. Further, when the cushioning material is used as a heating mat, for example, the cushioning material can buffer the pressure applied to the tube forming the circulation path 8 due to the weight of a person and prevent the circulation path 8 from being deformed. Therefore, the flow of the heat medium is good, and the heating / warming device that maintains a stable temperature state is realized.
