Photoelectric water heater

Abstract

The invention relates to a photoelectric water heater. The problems that an existing solar photoelectric water heater is low in light energy utilization rate per unit area, large in material consumption and high in cost are solved. The photoelectric water heater comprises a bracket which is provided with a water storage tank, a groove-type light-gathering plate and an energy-gathering pipe, and the groove-type light-gathering plate is arranged towards the sun. The groove-type light-gathering plate is focused to form a line, and the energy-gathering pipe is arranged on the focusing line of the groove-type light-gathering plate. Photovoltaic patches used for generating power are pasted to the outer wall of the side, facing the groove-type light-gathering plate, of the energy-gathering pipe. A storage battery is connected to the photovoltaic patches. The energy-gathering pipe is a hollow pipe. The two ends of the energy-gathering pipe are connected with the water storage tank to form cooling water circulation. According to the photoelectric water heater, the light energy utilization rate is greatly increased, and photoelectric material consumption of the photoelectric water heater is reduced.

Description

technical field [0001] The invention relates to a heating and power supply solution utilizing solar energy, relates to a solar water heater, and in particular to a water heater which utilizes solar energy to generate electricity and heat at the same time. Background technique [0002] As the concept of energy saving and environmental protection is deeply rooted in the hearts of the people, solar water heaters are more and more widely used. Regardless of the subtle changes in its structure, the traditional solar water heater adopts the vacuum tube heating method as its basic principle. This method has small heat dissipation, high thermal efficiency, and does not require complicated operation control, and is loved by the masses. The current common solar electric water heaters simply add an electric heating module to the solar water heater to provide an electric heating mode for the water heater under the weather conditions of insufficient light. Common solar electric water he...
