Heat storage device

The invention relates to a heat storage device, in particular to a local storage of local waste as a heat storage material and a heat storage cylinder, thereby saving the cost of transportation and manufacturing of the heat storage device, and fully utilizing the waste material resources. A heat storage device that reduces the benefits of environmental pollution.

According to the conventional device for heating the object to be heated, electric energy is used as the main energy source, and then the electric energy is converted into electromagnetic waves or heat energy to achieve the effect of heating the object to be heated.

However, with the increasing shortage of global crude oil resources, crude oil prices have skyrocketed. At present, countries all over the world are actively looking for alternative energy sources. The existing oil-replacement energy sources include hydropower, wind power, firepower, nuclear energy and solar energy. Among them, firepower and nuclear energy are easy to be environmentally friendly. And ecological pollution, the application of hydraulics requires the construction of dams, and the need for abundant water, such as the lack of electricity in the dry season, and the use of wind is geographically restricted, the need to find open and windy areas, and wind The source is lacking in stability and is difficult to concentrate on. The solar energy is spread throughout every part of the earth. It is universally used, is not restricted by the region, and is inexhaustible to provide sustainable use, and has the characteristics of clean and zero pollution. It has become the most important alternative energy source in the world today.

If the solar energy source can be effectively converted into thermal energy, it can replace the existing electric energy into electromagnetic Heating forms such as waves or heat energy will help solve the problem that today's expensive and environmentally-friendly crude oil is converted into heat energy after power generation to heat the object to be heated, thereby further reducing the user's use of crude oil due to soaring crude oil prices. The economic burden of increasing prices and achieving the environmental benefits of energy saving and carbon reduction is that today, solar energy heating devices have been developed and developed; however, the existing solar energy heating devices are quite expensive and must be installed. The parts materials are transported to the place to be assembled for assembly. If the installation location is in the field or abroad, the cost of freight will be more expensive, which will cause a heavy economic burden for the industry or consumers.

Therefore, the present inventors have in view of the above-mentioned many deficiencies of the existing heat storage devices, and have been supplemented by the manufacturing and design experience and knowledge of the related fields for many years, and have been innovated and improved for the existing heat storage devices by various ingenuity. The present invention was developed.

The present invention relates to a heat storage device, the main purpose of which is to provide a heat storage device which can take local waste as a component of a heat storage device to save the transportation and manufacturing cost of the heat storage device and reuse the material resources.

In order to achieve the above-mentioned implementation, the present inventors have developed the following heat storage device technology, which mainly includes a heat storage cylinder and a heat transfer unit, and the heat conduction unit is partially disposed in the accommodation space of the heat storage cylinder, and is also contained in the heat storage cylinder. The space content is provided with a heat storage material, which is one or a combination of sand, brick, cement, slag or shellfish, according to which local waste or materials can be obtained locally. As a heat storage material, it is possible to use a container such as a vacant container as a heat storage cylinder to save the cost of transportation and manufacturing of the heat storage device, and to make full use of material resources to effectively reduce environmental pollution and other environmental benefits.

Furthermore, the present invention uses solar energy as a heat source for heating to heat the object to be heated, effectively replacing the existing heating mode in which the object is heated by electric power to convert the heat to an object, so as to reduce the economy caused by the use of increasingly expensive electric energy. The burden and further achieve the environmental protection effect of energy saving and carbon reduction.
