This invention converts surplus electrical energy such as late-night electricity, power for adjusting load fluctuations, or highly variable energy such as sunlight, wind, and wave power into thermal energy and stores it, thereby providing stable thermal energy. This relates to a heat storage device that can be taken out as a heat storage device. [Prior Art] There have been various heating devices with a heat storage function, but most of them are panel-shaped containers such as panel heaters in which a general resistance heating element is sealed with a heat transfer medium. At the bottom, heat is stored using the sensible heat of the medium and surface heat is radiated through natural convection. There is also a regenerative electric heater made by Fukano Electric Power that consists of stacking brick-like heat storage blocks and inserting a resistance heating element between the layers. There are also electric water heaters for late-night power use that use water as a heat storage material and use sheathed wire heaters. [Problems to be solved by the invention] By the way, all conventional methods use sensible heat to store heat, and do not have constant temperature to maintain a constant output temperature during use, making it difficult to reduce the temperature economically. There was a problem in that it was not possible to obtain a product that satisfied the desired temperature for use. This invention was made in order to solve the above-mentioned problems, and aims to obtain a heat storage device having high electrical insulation properties and latent heat storage properties that improve the constant temperature of the usage temperature by utilizing latent heat. . [Means for solving the problem] The heat storage device according to the present invention uses a heat storage material made of high-density polyethylene whose surface or outer layer is stabilized by crosslinking and which absorbs and releases latent heat at around 130°C. It tightly surrounds and integrates the outer circumference of the body. [Function] In the present invention, heat is stored by absorbing thermal energy generated from the electrical resistance heating element into the heat storage material. By releasing the thermal energy stored in this heat storage material, heat at a constant temperature can be stably obtained. [Embodiment] Figures 1a and 1b are configuration diagrams showing the principle of an embodiment of the present invention, where Figure 1a is a front view and Figure 1b is a side sectional view taken along the - line in Figure 1a. . In these figures, 1 is an electric resistance heating element (hereinafter simply referred to as a heating element), 2 is a heat storage material, which is made of polyethylene that has been subjected to shape stabilization treatment, and has a temperature of about 130°C.
It absorbs and radiates latent heat of 200KJ/Kg.
In order to maintain an extremely high viscosity state even at high temperatures, the surface is crosslinked to form a high density.
Alternatively, the heat storage material 2 may have a two-layer structure in which the exterior is made of cross-linked polyethylene, or all of the heat storage material 2 may be made of high-density cross-linked polyethylene. Furthermore, the exterior may be made of metal or the like. 3 is a terminal for connecting the heating element 1 to a power source. The heat storage device configured as described above includes a heating element 1
are configured in close contact with each other, a terminal 3 is provided on the heating element 1, and an electric circuit is configured in accordance with electrical technical standards,
The latent heat is absorbed by storing thermal energy in the heat storage material 2 by supplying surplus power such as late-night power or by supplying unstable power, for example, generated by sunlight, wind, or wave power. Then, the input is stopped at a temperature at which the temperature starts to rise further, and a heat storage state is established. When it is desired to use the stored thermal energy, it can be transferred to a heat utilization device by removing a part of the insulation material (not shown in Figure 1) to radiate the heat, or by contacting a heat transfer medium such as gas or liquid. send. Next, Table 1 shows the properties of the high density polyethylene used in this invention.

As explained above, this invention integrates the outer periphery of an electrical resistance heating element by closely surrounding it with a heat storage material made of high-density polyethylene whose surface or outer layer part absorbs and releases latent heat at around 130°C and is stabilized by crosslinking. As a result, surplus electricity or unstable energy sources with large fluctuations such as sunlight and wind power can be converted into electricity, absorbed by the heat storage material, and released as heat at a constant temperature when used, producing stable thermal energy. can get. In addition, because polyethylene has good latent heat absorption, it does not get too hot and is easy to maintain.It is also lightweight, making it convenient to transport and install.
This has the advantage of providing a low-cost heat storage device.
