Abstract

A home concentrating generator and an accessory water heater thereof belongs to the comprehensive utilization field of the photovoltaic concentrating power generation and the concentrating water heater, mainly realizing that solar energy is converted to electrical energy in effective space and heat energy can be obtained efficiently. When the home concentrating generator is used, a concentrating device tracks the sun to rotate; a paraboloid-light-conversion head reflects the sunlight to obtain high power parallel light or similar parallel light, the parallel light shines on a concentrating battery board; the battery board is placed in the water heater so that water is used to reduce the temperature of the battery board and increase the generating efficiency, the water heater can obtain heat energy through the temperature reduction of the battery board, the two devices are complementary; and the current of the photovoltaic generating device can be increased through light-concentrating, thus reducing the area and cost of the battery board. Meanwhile, as part of the photovoltaic generating device is soaked in water for long time, good sealing and waterproofing measures are required. The method can be used for home power generation and in small-scale power generation projects and large-scale power plants, and have remarkable performance.

Description

Home concentrating generator and accessory water heater thereof

Technical field: photovoltaic generation, solar water heater

Background technology:

Concentrating photovoltaic power generation can be saved cost and raise the efficiency, and is exactly temperature rising behind the optically focused but run into a problem, and the temperature after the rising is to equipment and materials and all some influences of generating efficiency, and this also is the shortcoming of concentrating photovoltaic power generation.Simultaneously, the transformation efficiency of photovoltaic generation is not high, in the production about 10%, has the solar energy about 90% to collect and to become heat-energy losses in atmosphere in other words in the system of photovoltaic generation.

Relate to a kind of optically focused water heater in please number 200810080808x in the patent of invention, become the high density directional light after can assembling sunlight and extract from the below circular hole of condenser and enter water heater and absorb, the solar energy utilization ratio of water heater is higher.

Summary of the invention:

Mainly follow the tracks of sun rotation by beam condensing unit, by parabola is that the reflection of " change shaven head " obtains high power directional light or similar directional light, directional light impinges upon on the concentrator cell plate, cell panel is placed in the water heater and improves generating efficiency by water " cooling ", water heater obtains " heat energy " by the cooling to cell panel, both complementations, the device of photovoltaic generation has been saved cell panel area and cost because " optically focused " has increased electric current.The equipment component long period of soaking of photovoltaic generation needs better sealed knot and waterproof measure in water simultaneously.This way can be used for family's generating and small power generation engineering, and big power station also can use, and usefulness is remarkable

Description of drawings:

Fig. 1 is home concentrating generator and accessory water heater thereof schematic diagram.(1) is the parabolic device of optically focused, (2) be two paraboloidal coincidence focuses, 3) be that " changeing shaven head " parabolic (4) are the reflection ray behind the optically focused, (5) be sun parallel rays, (6) are light hole, and (7) are cell panel, (8) be the water heater attemperater, (9) be the waterproof circuit, (10) are energy storage battery, and (11) are support.

Embodiment:

As Fig. 1, home concentrating generator and accessory water heater thereof, follow the tracks of sun rotation by the parabolic device of optically focused (1), i.e. " commentaries on classics shaven head " (3) reflection of parabolic reflector device of passing through of its reflection ray obtains high power directional light or similar directional light (4), directional light is drawn by the following light hole (6) of optically focused parabolic lens (1) and is impinged upon on the concentrator cell plate (7), cell panel is placed in the water heater (8) and improves generating efficiency by water " cooling ", water heater obtains " heat energy " by the cooling to cell panel, both complementations, the device of photovoltaic generation has been saved cell panel area and cost because " optically focused " has increased electric current.Equipment component (7) and (9) long period of soaking of photovoltaic generation need better sealed knot, waterproof and heat conduction measure in water simultaneously.

Technical essential:

1, sunlight directional light (5) is transformed into high density directional light (4) by parabolic commentaries on classics shaven head (3) and tracking system, be that optically focused directional light afterwards has " high-energy ", similar laser character but than a little less than the laser, the circular hole of high-octane directional light below optically focused parabolic lens (1) injected following attemperater.

2, place poly-cell panel (7) in the attemperater internal vertical in parallel direction of light, size equates with the area of light hole is approaching, because size of current is directly proportional with intensity of illumination, and voltage changes not quite when temperature is low, so generated output is directly proportional with the optically focused multiplying power, saved battery sheet material so significantly and because direct light generating effect has been obtained in the application of tracking mode increases, because the temperatures involved that optically focused brings is by water for cooling.The height of cell panel is moderate, loss part infrared ray when wherein light is by water, but infrared ray just in time is difficult for being transformed into electric energy.So the cell panel height should not be too low, too low suitable loss of energy, the too high then heat conduction of unsuitable water.

3, conducting wire (9) need do the anti-middle temperature of waterproof and handle.Other controllers, inverter, storage battery (10) etc. are placed on outside the attemperater.

4, mounting system (11) only is a schematic diagram in the drawings, in practice since the sun not directly over and change with latitude and to have certain sun altitude, thereby optically focused parabola (1) tilts often, support Design is considered actual latitude variation and seasonal variations.

5, attemperater (8) can be provided with buffer tank according to seasonal variations, influence unfavorable factors such as generating efficiency and boiling water evaporation incrustation scale condenses so that prevent that summer temperature is too high, because attemperater is the attemperater of solar water heater, as long as it is big to guarantee that water temperature can design water tank greater than 40 ℃, therefore in order to prevent that the seasonal variations hot water temperature from can use the part of water tank not enough winter, establishes secondary water tank summer newly.
