Phase change heat storage solar water heater with self-adaptive cooling structure

Abstract

The invention provides a phase change heat storage solar water heater with a self-adaption heat dissipating structure. When a phase change heat storage material is overheated, hot gas is generated in a vacuum pipe; along with increment of the temperature, the gas pressure in the vacuum pipe is increased; the longitudinal elastic deformation length of an elastic cover bowl cup structure exceeds the gap height, so that the upper surface of a top plate of a metal heat conducting block is contacted with the bottom of a blind hole of a heat conducting flat plate to form a heat transfer channel from the top plate of the metal heat conducting block to the heat conducting flat plate; the hot gas in the vacuum pipe is dispersed to the top of the vacuum pipe; a vertical cylindrical heat exchange fin of the metal heat conducting block is condensed; and heat generated by condensation is transferred to the heat conducting flat plate from the metal heat conducting block of a self-adaption heat conducting device, and is transferred from a heat dissipating plate to surrounding environments, so that the temperature of the gas in the vacuum pipe is lowered, the stable pressure in the vacuum pipe is maintained, and the overheating protection of the phase change heat storage solar water heater is achieved.
