Panel light condensation type solar water heater without water tank

Abstract

The invention discloses a panel light condensation type solar water heater without a water tank. The water heater comprises a water heater combination outer frame (6), a galvanized steel sheet bottom plate (2), a heat tube tail support (5), a water storage type vacuum heat tube (3) and a tempered ultra-white glass cover plate (1), wherein the galvanized steel sheet bottom plate is installed on the bottom of the water heater combination outer frame (6), the heat tube tail support is installed on one side of the water heater combination outer frame (6), one end of the water storage type vacuum heat tube (3) is fixed on the heat tube tail support (5), the other end of the water storage type vacuum heat tube (3) is inserted in a polyurethane foaming heat-preservation module (4), and the tempered ultra-white glass cover plate (1) is installed on the top of the water heater combination outer frame (6). The water heater is reasonable in structural design, the water tank is not needed, the water heater can be integrated with a building, installation and maintenance are convenient to carry out, and the safety factor is large; moreover, the illumination area is large, the heat absorption rate is high, and the amount of stored heat is large; an optimized heat storage phase-change material is adopted, fresh hot water can be used instantly after being discharged, and the application range is wide.

Description

technical field [0001] The invention relates to the field of solar thermal utilization, in particular to a flat plate concentrating solar tankless water heater. Background technique [0002] Solar thermal technology provides broad prospects for solving energy problems in the future. At present, solar water heaters mainly include high borosilicate glass vacuum tube type and high-efficiency heat-absorbing blue film flat plate type. The vacuum tube has been developed for more than 20 years and the coating process is very mature. From single target to Multi-target magnetron sputtering coating technology, the heat absorption efficiency of the film layer has reached more than 94%, and the low-temperature anti-reflection rate has reached below 6%, which is in a relatively ideal state. As long as the production process is strictly controlled according to the mature process, it can produce high-quality products. High vacuum tubes, vacuum tube water heaters have very good advantages, ...
