摘要： PURPOSE:To restrain the creeping-up of heat accumulating material by a simple constitution and improve the heat accumulating density of the whole of a heat accumulator, by a method wherein, the belt of a substance, whole repels the molten latent heat accumulating material, is provided on the heat transfer wall on the side contacting with the latent heat accumulating material and the surface of a vessel at the upper part of the vicinity of the highest level of the surface of the latent heat accumulating material, which is fluctuated by the change of phase from solid into liquid, so as to be contacted with them closely. CONSTITUTION:A metallic heat transfer tube 2, whose upper end is opened, is filled with latent heat accumulating material 1. An annular belt 4, made of a substance, such as 4-ethylene fluoride or the like which repels the molten heat accumulating material, is attached to the inner surface of the heat transfer tube 2 at a place, slightly upper than the highest liquid level 3 when the heat accumulating material is molten, so as to be contacted with it closely. When the heat accumulating material 1 absorbs heat and is molten while the phase thereof is changed into liquid phase and the surface of the same has come to a position 3, the liquid creeps up until it arrives at the place upper than the height of the belt 4 if there is no annular belt 4, however, the creeping-up of the liquid may be precluded by repelling it by the annular belt 4 whereby an excessive space on the liquid level in the heat transfer tube may be decreased and the heat accumulating density of the whole of the heat accumulator may be improved.

摘要： PURPOSE:To make it possible to transfer heat horizontally and both horizontally and vertically without the application of a pump, by using a liquid which is turned into vapor phase when it receives heat at an endothermic section as a heat medium, and turned into liquid phase when it radiates heat at a heat radiation section in a closed-loop heat medium circulation passage where a heat medium is circulating inside, and placing the heat radiation section at a position relatively higher than the endothermic section. CONSTITUTION:Two liquid levels A and B of each heat medium fluid are produced within the range of an endothermic section 5 and a heat radiation section 7 during operation. The differential liquid level forces the heat medium fluid to flow from the heat radiation section 7 to the endothermic section 5. The endothermic action to the heat medium at the endothermic section 5 is mostly carried out at a liquid phase section. The heat medium fluid which has absorbed heat is vaporized and flows to the heat radiation section 7. The heat medium vapor is radiated and liquefied at the heat radiation section 7. When the opening of a control valve 10 is adjusted so as to comply with the requirements in terms of the quantity of intake heat energy or temperature, the liquid level of the heat medium is adjusted at the endothermic section 5 within the range from A and A', which makes it possible to take out a specified heat as a result. Moreover, the heat medium can circulate in a stabilized manner within a circulation passage 6.

摘要： PURPOSE:To keep the pressurizing force developed when part of a thermal storage material melts and expands from reaching construction members and promote the heat convection as a whole and improve heat transfer effects by heating the thermal storage material which reaches near the upper surface of the thermal storage material from the lower section of a space in a shell. CONSTITUTION:One or a plurality of subheaters 10 are provided which extend from the bottom section to near the upper surface between the tubes 2 installed in the space in a shell 1. This subheater 10 is provided with a wiring by which the subheater 10 is energized before a main heater 8 is energized or at the same time as it is energized. The upper section of the subheater 10 preferably projects somewhat on the upper face of the thermal storage material 7. Accordingly in thermal storage mode, while the main heater 8 is generating heat, the thermal storage material that melts and expands is pushed up to the upper surface of the thermal storage material 7 to let the pressure escape and the convection of the whole is promoted and the time of whole melting is shortened, because a flow channel has been formed from the lower side to the upper side of the thermal storage material by the heat generation of the subheater 10. By the way it is possible to use a heat-exchange coil through the inside of which a fluid with heat passes in place of the electric heater.

摘要： PURPOSE:To make it possible to use a low temperature heat medium, such as water as a high temperature heat medium, by connecting a high pressure holder to which non-condensable gas is sealed to a flow passage where high temperature fluid is flowing, and applying pressure to the liquid flowing in the passage. CONSTITUTION:An accumulation tank 1 is provided with a heat exchanger section 3 which transmits the heat accumulated in an accusation member 2 inside the accumulation tank to a heat medium inside, and a closed-shaped circulation passage 5 for heat medium including a heat exchanger section 4 which exchanges heat between a fluid to be used by heating and a heat medium. At the top of the ring-shaped passage 5 is connected a high pressure holder 6 to which none-condenced gas, such as nitrogen gas is sealed. A safety valve 7 is connected to this high pressure holder 6. It is desirable that all parts excluding the heat exchanger 4 between the accumulator 1 in the ring-shaped passage and the fluid to be used should be coated with insulation 8. On the way of the ring-shaped passage 5 installed is a pump which drives the heat medium if required. If a pressure which exceeds the pressure required to maintain the liquid phase is applied to the pressure prevailing in the ring-shaped passage, the vaporization in that part can be inhibited. At the same time, the damage to the system can be prevented as well.

摘要： PURPOSE:To prevent the generation of corrosion on a wall surface and restrain the creeping-up of heat accumulating material along the wall surface, by a method wherein an annular belt, made of a substance which repels the molten latent heat accumulating material, is provided on the surface of the heat transfer wall of a vessel, which makes contact with the latent heat accumulating material, between the highest level and the lowest level of liquid, which are fluctuated by the change of phase of the latent heat accumulating material from solid into liquid, so as to be contacted with the surface closely. CONSTITUTION:A metallic heat transfer tube 2 is filled with latent heat accumulating material 1 and heat medium flows the outside of the metallic tube 2. The level 3 of liquid fluctuates between the lowest liquid level L1 and the highest liquid level L2 in accordance with the degree of heat accumulation of the heat accumulating material 1. An annular belt 4, made of a substance, capable of enduring the heat accumulating temperature of the heat accumulating material 1 and having a property to repel the molten heat accumulating material such as 4-ethylene fluoride resin or the like, is attached to the inner surface of the heat transfer tube 2 so as to be contacted closely with the inner surface along a range A slightly wider in up-and-down than a range between the liquid levels L1, L2. When the heat accumulating material 1 is molten by the accumulation of heat and the level of the liquid is fluctuated, the liquid is repelled by the belt 4 and the level 3 of the liquid is protruded from the contacting part with the annular belt 4, therefore, the creeping-up of the liquid will never be generated. Accordingly, an excessive space above the highest liquid level L2 may be reduced and the surface corrosion of the tube 2 in the section between the levels L1, L2 may be prevent.

摘要： PURPOSE:To raise the heat transfer efficiency without developing unnecessary stresses to a tube and shell by providing fins lined longitudinally in the up-and-down direction in the outer face of each tube and constituting the fines provided on the upper side of the tube in the highest stage so as to make the upper brims of those fins reach near the upper surface of a latent heat storage material at least when it solidifies. CONSTITUTION:In the inside of a cylindrical shell 1 a plurality of tubes 2 are arranged, and in the tube 2 a heat medium fluid flows through to give external heat to a latent heat storage material 3 and plays the role to take out the heat stored in the latent heat storage material to the outside. At the upper and lower sections of the tube 2 a longitudinally running fin 5 s provided in the vertical plane passing through the center of the tube 2, and the fine is formed as one body with the tube 2 by the forming methods such as drawing, extrusion, welding, mechanical joining, etc. and the end brims that are mutually opposite are vertically connected. As a result, the thermal storage material near the tube 2 and fin 5 transfers the heat of the heat medium excellently during thermal storage mode, and a liquefying section penetrating the shell in the up-and-down direction is formed, and heat convection occurs with a raised heat transfer efficiency. Furthermore, in heat radiation mode a solid plate-shaped section of a thermal storage material extending up-and-down in the shell is formed on the contrary so that the mechanical strength is raised and damage is prevented.
