Therefore, you can work outdoors while keeping your hands warm even in the cold winter, or engage in sports and leisure activities such as golf, fishing, and skiing.

Meanwhile, the present invention may further include a heat dissipation sheet and heat exchange balls as another example.

5 and 6, the present invention is installed between the inner shell 11 and the shell 12, the heat radiation sheet 50 covering the heating wire 20, and between the heat radiation sheet 50 and the shell 12. It further includes a plurality of heat exchange balls 60 accommodated.

The heat dissipation sheet 50 is attached to the endothelium 11 corresponding to the side surface of the finger 5 on which the heating wire 20 is installed. The heating wire 20 is positioned between the endothelium 11 and the heat dissipation sheet 50 .

The heat dissipation sheet 50 receives heat from the heat wire 20 and serves to spread the heat widely. Accordingly, heat is concentrated in the heating wire 20 to prevent it from becoming hot, and heat is diffused around the heating wire 20 so that heat can be uniformly transmitted to the fingers. As the heat dissipation sheet 50 , a graphite sheet formed by adding graphite to a synthetic resin to form a thin sheet may be used.

A plurality of heat exchange balls 60 are accommodated between the heat dissipation sheet 50 and the outer shell 12 .

The heat exchange ball 60 is made of a spherical elastic pack 61 having an empty inside, and a phase change material 65 filled in the elastic pack 61 .

The elastic pack 61 is made of a sphere having an outer diameter of 1 to 5 mm. The elastic pack 61 has a structure in which the inside is empty so that the phase change material can be filled therein. The elastic pack 61 is formed of an elastic material that can be elastically deformed. As such an elastic material, a flexible synthetic resin material such as rubber or silicone may be used.

Preferably, the elastic pack 61 has a structure in which a thermally conductive filler is dispersed in a synthetic resin to facilitate heat transfer. For example, an elastic pack may be made by injection molding a composition composed of 10 to 30% by weight of carbon, 40 to 80% by weight of polyethylene, and 5 to 40% by weight of elastomer.

A phase change material (PCM) refers to a material that absorbs or emits energy without a change in temperature during a phase change into a solid or liquid. A phase change material absorbs or releases latent heat in an isothermal state during a phase change between a solid state and a liquid state. Since the phase change material that stores thermal energy by such a phase change absorbs or releases latent heat, it can store a larger amount of thermal energy than a general thermal storage material. The phase change material absorbs and stores heat when it rises above the phase change temperature, that is, the melting point, and releases the stored heat when it falls below the melting point to maintain a constant temperature.

In the present invention, a material having a phase change temperature at 40 to 60° C. may be used as the phase change material. For example, in the case of using a phase change material having a phase change temperature at 50° C., when the ambient temperature reaches 50° C., the phase change material absorbs heat as the phase change proceeds from a solid state to a liquid state. And when the ambient temperature is less than 50 ℃, the phase change material emits heat as the phase change proceeds from the liquid state to the solid state.

As such, the heat exchange ball 60 filled with the phase change material 65 absorbs and stores heat while changing the phase when the heating wire 20 generates heat. And when the heating wire 20 does not generate heat, the heat is emitted while changing the phase again. Therefore, even if the battery is discharged, you can keep your hands warm for a certain period of time. In addition, when there is a heat source around the user, if the glove is placed around the heat source, the phase change material absorbs and stores heat, so it has the advantage of keeping hands warm for a certain period of time even if the heating wire is not operated.

In the above, the present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom. Accordingly, the true protection scope of the present invention should be defined only by the appended claims.
