熱器と放熱器を内装した構成が開示されている。Natural circulation type solar heat collection devices, which fill a heat storage tank with water and collect heat by natural convection between the heat collector and the heat storage tank, have different amounts of heat storage due to differences in hot water consumption. It was necessary to produce and stock several types, which was an impediment to improving productivity.Therefore, in such solar heat collectors, heat storage tanks with relaxed restrictions on the amount of heat storage, that is, heat storage tanks that increase the amount of heat storage, were used. As soon as it became desirable to create a tank, it was opened in 1982-24.
It has been proposed as Publication No. 461. In other words, there is a heat collector in which the working medium is warmed by solar heat, a radiator in which the working medium heated by the heat collector circulates through natural convection, a heat exchanger in which water passes, and two-phase change between liquid and solid phases. A configuration is disclosed in which the heat storage tank is comprised of a heat storage tank filled with the utilized latent heat storage material, and the heat collector and heat radiator are installed inside the heat storage tank.

い問題がある。According to this configuration, heat transfer between the heat radiator through which the working medium flows, the heat storage material forming a solid phase in the heat storage tank, and the heat exchanger through which water flows is poor, and therefore the heat extraction efficiency from the heat storage material is low. There's a problem.

The filter is a circulation pipe that includes the water heat pipe of the heat collector 1 and forms a closed circuit with the heat storage tank 2. The hot water heated in the heat collector 1 rises through the circulating vibro and is poured into the heat storage tank 2. The low-temperature water in the heat storage tank 2 descends through the circulation pipe filter and reaches the heat collector 1, where it is warmed by solar heat, forming a natural circulation type solar heat collecting device. 4 is a heat storage device, and this heat storage device 4 is built in the heat storage tank 2. As shown in FIG. 5, this heat storage device 4 is a latent heat storage material that generates latent heat as a result of a two-phase change between a liquid phase and a solid phase in a hollow 6 of a watertight outer shell 5 made of, for example, a metal material or a synthetic resin material. It is constructed by enclosing 7. Here, the water cap-shaped shell 5 is provided with a large number of through holes 15 passing through the top and bottom.

１０から採湯される。In other words, hot water collection using a natural circulation type solar heat collection device in which water circulates between the heat collector 1 and the heat storage tank 2 can be performed with high heat collection efficiency. That is, the hot water heated by the heat collector 1 while circulating between the heat collector 1 and the heat storage tank 2 is drawn from the hot water sampling pipe 10 of the heat storage tank 2.

る。While the hot water is being stored in the heat storage [2], the hot water gives heat to the latent heat storage material 7 of the heat storage device 4, which is formed by enclosing a latent heat storage material 7 in a watertight outer shell, and when the latent heat storage material 7 reaches its melting point. The phase changes from a solid phase to a liquid phase, and the hollow 6 of the watertight outer shell 5 is sealed in the liquid phase. If hot water is drawn from the hot water sampling pipe 10 without supplying water to the heat storage tank 2 from the water supply pipe 11, the supplied low-temperature water will react when the phase of the latent heat storage material 7 constituting the heat storage tank 2 changes from the liquid phase to the solid phase. It is heated by the latent heat it releases. In other words, the hot water supplied from the heat collector 1 and the latent heat storage material 7 that reaches the melting point and forms a liquid phase are heat transfer between liquids with the watertight outer shell 5 in between, and compared to heat transfer between the same liquids. The amount of heat transfer increases, and the latent heat storage material 7 is heated by the latent heat when the phase changes from the liquid phase to the solid phase, so that the heat collection efficiency increases. Since this type of latent heat storage material 7 has the same heat storage capacity as water with a volume of 1/6 to 1/6 of water, the problem can be solved by increasing the volume of the heat storage device 4 without increasing the volume of the heat storage tank 2. can do.

従って採熱量の増大に効果的である。Furthermore, a latent heat storage material 7 is sealed in the hollow filter of the watertight outer shell 5 having a number of through holes 13 that vertically penetrate the heat storage tank 4, and this is divided into upper and lower sections when the heat storage tank 2 is built in. When the high-temperature area 9 and low-temperature area 8 are formed, the heat storage tank 2
Since it passes through the through holes 8 during the process of convection from top to bottom that occurs inside the latent heat storage material 7, it is possible to increase the amount of heat stored in the latent heat storage material 7.
Therefore, it is effective in increasing the amount of heat collected.

The heat exchanger 12 may be provided in the heat storage tank 2.

るので採熱効率が高まるのである。As described above, in this invention, heat transfer between the hot water supplied from the heat collector 1 and the latent heat storage material 7 which has reached the melting point and turned into a liquid phase occurs between a liquid and a liquid by sandwiching the watertight structure 5 between them. The amount of heat transfer is increased compared to the heat transfer of , and the water in the heat storage tank 2 is heated by the latent heat when the latent heat storage material 7 changes from the liquid phase to the solid phase, so the heat collection efficiency increases.
