Problems solved by technology

[0004] When there is excess solar energy, the water temperature in the solar water heater will be very high, causing the internal heat pressure of the solar water heater to be too high. Especially in the case of external water cut-off, the high heat pressure will bring great safety hazards. Neither the traditional solar water heater nor the solar phase change heat storage water heater is equipped with protection devices against water cutoff and overheating, making safety performance a problem for the promotion and application of solar water heaters

Abstract

The invention relates to a water-break overheat protector and a solar phase-change heat accumulation water heater with the same. The solar phase-change heat accumulation water heater comprises a plurality of solar collector tubes, a water inlet tube, a water outlet tube, a thermal insulation layer, a plurality of phase-change heat accumulators and a water-break overheat protector, wherein the phase-change heat accumulators are arranged in the solar collector tubes; the water inlet tube is sleeved in the water outlet tube; the water outlet tube is connected with the phase-change heat accumulators; the water-break overheat protector is respectively connected with the water inlet tube and the water outlet tube; and the thermal insulation layer is covered on the water outlet tube, the connection port of the water outlet tube and the solar collector tubes, and the outside of the upper end of each solar collector tube. The water-break overheat protector and the solar phase-change heat accumulation water heater with the same can naturally dissipate heat under water-break overheat conditions and effectively prevent the phase-change heat accumulators from overheating, thereby greatly enhancing the safety performance of the solar water heater.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a water cut-off and overheating protection device and a solar phase change thermal storage water heater with the device. Background technique [0002] At present, solar water heaters are mostly vacuum tube solar water heaters, including heat collectors, heat preservation water tanks, connecting pipes and brackets. It is installed between the tray on the lower part of the front side of the bracket and the thermal insulation water tank, and the connecting pipe is arranged in the heat collector and the thermal insulation water tank to transport hot water from the heat collector to the thermal insulation water tank and cold water from the thermal insulation water tank to the heat collector device. [0003] The new development trend of solar water heaters is the use of phase change materials, which are placed in the heat preservation water tank or heat collecting pipes. The phase change materi...
