Abstract

A light energy converter comprises a light-gathering device, a sunshine follower, an energy converter, and a bracket, wherein the light-gathering device is groove-shaped, the front and the rear groove faces are light-gathering paraboloids, the energy converter is installed on the bottom of the light-gathering device, which is formed by a solar-energy battery array and a line of heat-transmission water tubes which are arranged on the lower portion of the solar-energy battery array and are closely appressed with the solar-energy battery array. The solar-energy battery array is lined up on the light-gathering face on the bottom of the light-gathering device which is connected on the bracket through the sunshine follower. The light-gathering device of the light energy converter can gather solar radiant energy with low density on the solar-energy battery array, and changes light energy into electric energy. Water circulates downside of the heat-transmission water tubes, which keeps temperature of the energy converter lower than 55DEG C through the cooling of water at the one hand, and greatly improves energy conversion ratio and cost performance of the solar-energy converting device by heating cold water into hot water and utilizing the hot water at the other hand.

It is the device of electric energy and heat energy by solar energy converting that the utility model relates to a kind of.

Background technology

Utilize solar energy converting to be employed for the photovoltaic generation of electric energy, utilize solar energy converting also to be widely used for heat energy, as solar water heater, but present existing device for converting solar energy is because of function singleness, the ubiquity energy conversion rate is low, problem of ultra-high price, there is significant limitation in its scope of application.

Summary of the invention

The purpose of this utility model provides a kind of energy conversion rate and cost performance height, and electric energy can be provided, and the light energy converter of heat energy can be provided again.

The utility model by the following technical solutions, designed light energy converter is by concentrator, the sunshine tracking device, energy converter is configured to propping up, described concentrator is a flute profile, groove face is the optically focused parabola before and after it, described energy converter is installed in the bottom of concentrator, it is by solar battery array and be installed in the solar battery array bottom, and constitute with row's heat transfer water pipe that solar battery array is close to, described solar battery array cloth comes on the caustic surface of concentrator bottom, and described concentrator is mounted on the support by the sunshine tracking device.

In this light energy converter, concentrator is parabolic, a kind of condenser mirror of high reflectance, and it can improve 4 times with the low-density solar radiant energy, and accumulates on the energy converter; Tracker can rotate on North and South direction, and the daylighting of guaranteeing concentrator is in the face of accurate sunlight, to accept maximum radiant energy; Be covered with solar battery array above the energy converter, change luminous energy into electric energy, following heat transfer water pipe has boiler water circulation to flow, and by the cooling of water, makes the temperature of energy converter remain below 55 ℃ on the one hand, on the one hand cold water is heated into hot water.

This light energy converter is realized utilization to the solar energy converting energy by the accumulator that is connected with energy converter.Described accumulator comprises electric energy accumulator and thermal energy storage device, described electric energy accumulator comprises controller, storage battery, the output of the solar battery array of energy converter is connected to controller by the input of electric energy accumulator, under the control of controller, electrical power storage directly is used in storage battery, or changes alternating current output utilization into through inverter again; Described thermal energy storage device forms boiler water circulation with the heat transfer water pipe of energy converter and is connected, and cold water is heated into hot water is used.

This light energy converter compact conformation, easy to use, electric energy can be provided, also can hot-water supply, both be suitable for family and used, also can be industry, the hotel provides large-scale electric energy and hot water service, the energy conversion rate height, cost is low, and practicality is big.

Use proof, a daylighting area is 2.65m ²Light energy converter, be 1000W/m in light intensity ²Under the condition, can produce electric energy every day is 3.5Kwh for 360 watts, produces heat energy 8.8Kwh simultaneously, and gross energy is 12.3Kwh.Energy conversion rate is up to 50%, and this light energy converter is compared with unifunctional plate type solar photovoltaic generation and unifunctional solar water heater, is producing under the equal energy condition, and cost reduces by 70%.
