Solar heat collecting cake

Abstract

The invention discloses a solar heat collecting cake, which comprises a cake body and heat storage materials in the cake body. A transparent cover plate is arranged on the upper surface of the cake body. A heat absorbing plate is arranged in the cake body and is in contact with the heat storage materials. The invention takes solar energy as source energy, rays are transmitted to the heat absorbing plate through a transparent plate, the heat absorbing plate converts optical energy into heat energy and the heat energy is transferred to the heat storage materials through heat transfer medium. The cake body can be made of hard material, the heat storage materials can be solid heat storage materials, and the heat storage materials are enclosed by hard cake materials. The structure and the materials are not apt to cause explosion. Even though explosion occurs, the external hard materials enclosing the heat storage materials are just cracked, the internal heat storage materials are not spilt disorderly and the safety of other people is not endangered. The invention has the advantages that the natural resource is fully utilized, the electric energy and the hydraulic energy are saved, the occurrence probability of serious accidents is reduced, and the safety factor and the thermal efficiency are improved.

Description

Technical field [0001] The invention relates to a heating device, in particular to a solar thermal heating cake. Background technique [0002] In the cold winter, heating equipment is indispensable. The hot water bottle is the most primitive type. A high-temperature liquid is poured into a leather bag made of rubber, and the principle of heat conduction is used for heating. However, when the water temperature drops, the hot water must be replaced. The water resources are too wasteful. After that, another kind of heating bag called Dianwanbao appeared. Dianwanbao was filled with conductive liquid into a soft waterproof cloth bag. There was an electrical socket on the surface of the bag. When the water temperature in the bag dropped, the electricity would pass through. The socket is energized and conducts heat, so that the heating bag warms up again. Using this kind of heating bag does not need to replace the cold water in the bag, which is indeed much more convenient. However, i...

Problems solved by technology

Using this kind of heating bag does not need to replace the cold water in the bag, which is indeed much more convenient. However, if the heating temperature control of the electric heating treasure fails, the water will vaporize and expand in volume due to continuous heating, causing an explosion, and sometimes even severely scalding the user. The safety factor is very low.

In addition, the power of electric heaters is very high, generally 500 watts, and it is still a relatively power-hungry product.
