Phase-change energy-storage bidirectional-heating quartz glass tube water heater and heating device thereof

Abstract

The invention provides a phase-change energy-storage bidirectional-heating quartz glass tube water heater and a heating device thereof. The phase-change energy-storage bidirectional-heating quartz glass tube water heater comprises a water heater outer shell, a heat-preservation isolation layer, an inner container shell, a graphene carbon nano heating tube, an inner coating film heating tube, a protection shell upper cover plate, a protection shell lower cover plate, an outer coating film heating tube, a protection shell lower cover plate, a silica gel sealing gasket, a temperature sensor, a heat exchange coil, a graphene carbon nano heating tube protection shell, a phase-change energy-storage medium, a circuit control system and the like. By means of the heat storage and energy storage characteristics of the phase-change heat storage and energy storage medium in the process of converting from the solid state to the liquid state, electric energy can be stored at night and released and used in the daytime. The graphene carbon nano heating tube protection shell is provided with a cold water inlet and a hot water outlet. The heat exchange coil, the graphene carbon nano inner coating film heating tube, the graphene carbon nano outer coating film heating tube and the graphene carbon nano heating tube protection shell are combined to form the heating device. A preheating and cyclic heating water channel is formed through the heat exchange coil arranged in the phase-change energy-storage medium.

Description

Technical field: [0001] The invention relates to the field of electric water heaters, in particular to a phase change energy storage bidirectional heating quartz glass tube water heater and a heating device thereof. Background technique: [0002] There are two types of electric water heaters in the existing market: instant heating type and water storage type. Due to the high power of the instant heating type water heater, there will be potential safety hazards in household use. The other type is water storage water heater. Due to the large volume of the water storage tank and the structural design to prevent corrosion of the inner tank, magnesium rods will be installed to overcome the scaling of the metal electric heating rod and the corrosion of the inner tank of the water tank. . The potential of the magnesium rod used to prevent corrosion of the water tank liner is generally around -1.7. Such a high potential will cause a sudden increase in the potential of the water tan...

AI Technical Summary

Problems solved by technology

The potential of the magnesium rod used to prevent corrosion of the water tank liner is generally around -1.7. Such a high potential will cause a sudden increase in the potential of the water tank liner and the heating tube to form over-protection, resulting in rich A large amount of ions are collected to accelerate the generation of scale. Since the magnesium rod will gradually be exhausted within 1-2 years, the inner tank of the water tank will gradually begin to corrode, and the metal electric heating rod will form scale, which will eventually cause the water tank to leak

After the metal electric heating rod is wrapped with scale, it will affect the heat conduction efficiency and cause safety accidents. Lon
