Phase change temperature control vacuum tube anti-explosion booster water heater

Abstract

The invention relates to a phase change temperature control vacuum tube anti-explosion booster water heater. A light condensing plate is tightly connected to a phase change heat storage shell by usingreinforcing ribs; the phase change heat storage shell is filled with gradient phase change materials; an insulation water tank is arranged at the lower part of the gradient phase change materials; acold water preheating pipe penetrates through the gradient phase change materials to enter the insulation water tank; the insulation water tank consists of a preheated water collecting box and hot water collecting box, which are separated through a cold-hot separation plate; one end of a vacuum glass tube communicates with the preheated water collecting box, and the other end communicates with thehot water collecting box; and after preheated water is heated by the glass vacuum tube, the density of hot water is reduced, and the hot water is ascended along the lower part of the vacuum glass tube to enter the hot water collecting box, and is output by a hot water outlet. The problems of bursting of the glass vacuum tube and lower heat collecting efficiency caused by nonuniform temperatures of cold and hot water in the inlet and the outlet under the sun solarization condition can be effectively solved; the temperature difference between the fed water of the vacuum tube and high-temperature inner wall surface can be obviously reduced; and meanwhile, the absorption efficiency of solar power is prominently improved to achieve the effect of instant use of the hot water.

Description

technical field [0001] The invention relates to a vacuum tube explosion-proof and synergistic water heater, in particular to a vacuum tube explosion-proof and synergistic water heater with phase change temperature control. Background technique [0002] Although solar energy has many advantages such as inexhaustible supply, it also has defects such as low energy density and inability to continuously supply energy. Therefore, in order to efficiently use sufficient solar energy during the day for use at night or on cloudy days, or to use solar energy in summer for heating in winter (seasonal heat storage), it is necessary to ensure efficient and safe operation of solar water heaters. Therefore, preventing the vacuum tube of the water heater from bursting and improving the heat collection efficiency of the vacuum tube are problems that need to be solved urgently at this stage. [0003] At present, the heat collector tubes of household solar water heaters include vacuum glass tu...

Problems solved by technology

[0006] The technical problem to be solved in the present invention is to solve the problems that the vacuum tube of the solar water heater is prone to bursting and the heat collection efficiency is low when it works in a high temperature environment, and proposes a vacuum tube explosion-proof synergistic water heater based on cascade phase change temperature control, which can avoid sun exposure At the same time, suddenly adding cold water into the vacuum tube will cause the tube to burst, which significantly improves the heat storage effect of the solar water heater, and at the same time achieves the effect of instant use without adding an auxiliary heating device.
