When the set temperature is entered or input in this manner, when the ambient temperature is higher than the set temperature, the phase change material 20 changes from a solid to a liquid to absorb ambient heat, while when it is lower than the set temperature, the phase change material The 20 changes from liquid to solid to release heat to the surroundings, thereby increasing the ambient temperature, thereby providing heat to the user or the object.

In addition, the heating device according to the present invention includes a heating member 30 for directly applying heat to the phase change material 20 impregnated in the support member 10.

It is preferable that the heat generating member 30 is formed of a metal plate having excellent thermal conductivity. Of course, the heat generating member 30 is preferably formed of a thin plate or plate that can maintain a constant strength to have a suitable solubility according to the purpose or purpose of use. Of course, the heat generating member 30 is connected to a power source is connected to a power supply 32 formed of a wire or wire to supply energy or heat source.

On the other hand, the heating device according to the present invention protects the above-described support member 10, the phase change material 20 and the heating member 30, and shielding the outside and the exterior member 40 for supplying heat to the outside as well ). The exterior member 40 completely surrounds the entire support member 10, the phase change material 20 and the heat generating member 30, and keeps airtight as well as liquid tight to prevent leakage of the phase change material 20. It can be.

The exterior member 40 is preferably formed of a material having thermal conductivity as well as an effective thermal conductivity to easily provide the heat released by the phase change of the phase change material 20 to the outside. Examples of such materials are aluminum, polycarbonate, silicone, vinyl, synthetic resins, and wraps.

It is impregnated to form one binder (A) and absorbs latent heat while phase-changing from solid to liquid at a predetermined temperature, or releases heat while phase-changing from liquid to solid. The phase change material 20 which maintains flexibility, and the support member 10 and the phase change material 20 are completely enclosed in airtight and liquid-tight and shield the heat from the phase change material 20 to protect and shield from the outside. It is composed of only the exterior member 40 for transmitting to the outside. In this case, the heat or heating element 30 provided from the outside of the heat generating device is in contact with the exterior member 40 and the phase change material 20 is thermally stored or absorbed by heat generated therefrom. Of course, the heat generating member 30 may be selectively installed or contacted on one side or both sides of the exterior member 40. Hereinafter, a method of manufacturing a heating device according to the present invention configured as described above will be described in detail with reference to FIGS. 7 to 10.

First, the worker or manufacturer determines and prepares the support member 10 and the phase change material 20 having a predetermined impregnation ratio (S100). Here, the support member 10 is preferably formed of a fiber having a pore or more than a predetermined range, and particularly preferably a nonwoven fabric in which the impregnation ratio is maintained at 80% to 95% with respect to the volume of the entire support member 10. In addition, the phase change material 20 is prepared in a liquid state and prepared by selecting one of an organic phase change material or an inorganic phase change material according to the object and purpose to be applied.

Here, the molding frame (F) is open at its top to place and pour the support member (10) and the phase change material (20), each side and the bottom is closed so that the entirety of the phase change material (20) after curing It is possible to maintain the shape and to prevent the phase change material 20 from leaking or leaking to the outside.

Subsequently, the support member 10 is arranged in a predetermined arrangement in the prepared molding die F, and then a phase change material 20 is poured to impregnate the support member 10 to form a combination A (S104). Of course, the coupling ratio between the support member 10 and the phase change material 20 is performed at a predetermined ratio corresponding to the intended use and purpose.

Next, the combination A of the support member 10 and the phase change material 20 formed in the molding die F is cooled and cured (S104). The cooling and curing may be performed naturally at room temperature, but may be dried and cured by a separate drying or cooling means. Particularly, it is preferable that the binder A is not completely cured even after curing, and the flexibility is maintained because the cure of the phase change material 20 is prevented by the continuity of the support member 10.

After the assembly (A) in the mold (F) is completely cooled at room temperature to complete the curing, the assembly (A) is removed from the mold (F) (S106).

Next, after the worker prepares the heat generating member 30 and the exterior member 40, the operator arranges the heating member 30 on the exterior member 40 and the combination of the support member 10 and the phase change material 20 thereon. In a state in which (A) is disposed, the assembly A and the heat generating member 30 are completely surrounded by the exterior member 40 to complete the heat generating apparatus (S108).

In addition, according to one feature of the present invention can be applied to a heating device, such as a boiler installed on the floor or wall of a house or building, or a cooling tower. In this case, the support member 10 may be used only in a state in which the phase change material 20 is impregnated.

According to the method of use, when the power supply unit 32 is connected to a power socket (not shown), the power is supplied to the heat generating member 30 and simultaneously generates heat. The heat generated in this way is transferred to the phase change material 20, the phase change material 20 of the semi-solid state is changed to a liquid phase to absorb heat, and the heat absorbed in this way is transferred to the phase change material 20 itself. Is regenerated. Of course, even in such a state that the heat is supplied to the outside of the heating device to provide a warm state or heating state to the user.

Thereafter, in a state in which heat is sufficiently stored in the phase change material 20 after a predetermined time has elapsed, even when the application of the power supply by the power supply member 42 is stopped, the heat accumulated in the phase change material 20 remains. The heat is supplied to the outside to provide continuous heat.

In particular, according to the heat generating device according to the present invention, even when the phase change material 20 continuously radiates heat to completely dissipate heat, the phase change material 20 is not completely cured by the support member 10. Since the semi-solid state is maintained, the user is provided with a soft and soft feeling, thereby giving the user comfort without any inconvenience.

In addition, even when the heat is completely released, because the user is flexible, the user can continuously maintain the applied state by deforming to a specific part of the body, so that it can be conveniently and variously used.

Therefore, the heating device according to the present invention can be applied appropriately and easily regardless of the shape and position of the object to which it is installed or mounted.

While a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
