The alternating voltage of 110V, 220V, 380V.Cell piece is at least concatenated by 280 or more, and one layer is spread on the aluminum enclosure of heat exchanger
The cell piece of several concatenations is placed above in EVA glue, then spreads one layer of EVA glue above the cell piece concatenated at several, also
It can not also be spread in one layer above of one layer of EVA glue upper berth woven design tempered glass, it is true finally to increase temperature pumping with laminating machine
Sky has been made into the battery component module being connected by several cell pieces with heat exchanger, has added silver paste when processing cell piece
Slightly, welding is widened, and reduces line loss and power consumption.
Condenser 1 is equipped with above several concatenated cell pieces 5, condenser is hemispherical or is less than hemispherical, is gathered
Light device is made of spherical hollow space lens 2 and optically focused funnel 4, so that several concatenated cell pieces 5 are poly- by same condenser 1
Light.The heat exchanger 7 is installed on 8 internal upper part of water tank, and installation temperature control water pump 10 is placed on the water inlet pipe 9 or outlet pipe 11 of heat exchanger
In water tank, can also be not interposing in water tank with the water inlet pipe of heat exchanger, outlet pipe and temperature control water pump, the water inlet pipe 9 of heat exchanger or
Outlet pipe 11 is connected by the water system in temperature control water pump and other places；Generator unit is arranged in the upper surface that heat exchanger exposes water tank, will
Through heat exchanger transfer into water, circulating hot water makes full use of the heat that generator unit generates.There are two types of water tanks: one is outside aluminium
Thermal insulation material is not added in shell, outside, and water is filled in the inside, and the watt level of water capacity apparent sun energy generator unit and daily calorific value are big
It is small, and how much the temperature rise of control determine, is cooled down by self circulation heat exchange；Another kind uses the water tank with thermal insulation material, side
Method principle is same as above, and this water tank can form big hot-water heating system.
In Fig. 2, due to using solar concentrator 1, light intensity improves tens times on several concatenated cell pieces 5, temperature
Degree also steeply rises, the photoelectric conversion capacity of cell piece also rapid decrease, thus by cell piece bottom surface to be greater than battery unilateral
Long-pending heat exchanger and water system, by the heat fast exchange of several concatenated cell pieces into water system, low cost, Gao Ke
It leans on, rapid heat dissipation, temperature regulable, ensure that the normal work of solar power generation unit.Specific method is: with copper pipe be made into " u "-shaped or
The heat-dissipating pipe 13 of serpentine, the both ends of pipe are water inlet pipe 9 and outlet pipe 11, the more copper pipes in one side of heat exchanger or polygon setting
14, copper pipe one end is communicated with water tank 8, and the other end is connected but is not communicated with heat-dissipating pipe 13, its effect is to increase radiating surface and mention
High thermal convection amount has been made heat exchanger 7 for aluminium casing is cast into aluminium outside heat-dissipating pipe and copper pipe.
In shown in Fig. 3, the exchange of the solar power generation unit of several solar hydroelectric integration power generation systems is exported
It holds to form the capacity not equal solar power plant that generates electricity with being connected with power grid, any unit goes wrong can very convenient off-network
Repair and maintenance, greatly improves the reliability and work efficiency of solar power plant, and group station is convenient, reduces the cost built a station, can be with
Accomplish very powerful power station from basic unit；By the radiator drain 12 of several solar hydroelectric integration power generation systems
Or heat exchanger outlet pipe 11 is connected to form solar heat reservoir, occupied area is small, and generating efficiency is high, is convenient for family, industrial and mining enterprises
And extensive power station etc. uses.
Fig. 4, shown in 5 in, present invention employs three-level anaclasis principle, will in the morning, afternoon and evening omnidirectional incident sunlight through collecting
Light, astigmatism, optically focused multi-order refractive are under optically focused funnel on several concatenated cell pieces of mouth.That is the light of any direction incidence
After spherical hollow space lens enter light refraction at spherical surface aggregation, spherical sky is diffused by light is regular by several annular corner angle mirrors
Below chamber lens inner cavity, the most reflective inner wall afterwards through optically focused funnel is reflexed under optically focused funnel on several cell pieces of mouth.
Primary spherical light harvesting is according to ball focusing principle, the multi-direction focusing of ball energy, when light is in upper half spherical surface any angle
When incident, focus all falls in the lower section of lower semisphere, and focus is moved with the movement of light.According to principles above, the present invention
Medicine ball is changed to the hollow lens of hemispherical, the hollow lens of hemispherical are horizontally arranged, when sunlight makees two dimension around hemisphere face
When movement, sunlight is that center axis is gathered in along the incident light axis perpendicular to spherical surface after the refraction of hemisphere incidence surface by parallel rays
Below ball, due to being that bulbus cordis, the aggregation finally formed focus of light are far longer than the diameter of ball in midair, Focus Club is with light
The movement of line and move, also not up to fall light is fixed in one plane, with the purpose that sunlight is mobile and is displaced.
On this basis, by second level reflect astigmatism, the hollow lens of hemispherical several of inner wall one-pass molding successively
The annular corner angle mirror of connection, the focal length after making incident hemisphere incidence surface form very long aggregation light, through several annular corner angle
It is regularly spread after mirror refraction to the hollow lens inner cavity lower section of hemispherical.Specifically, due to a corner angle side of annular corner angle mirror
Perpendicular to incidence surface, angle α≤45 ° of the formation of another corner angle side and incidence surface, and the extended line on the corner angle side and spherical shape are empty
The intersection of chamber lens inner cavity bottom edge rolls over the aggregation light after incident hemisphere incidence surface through the wide corner angle side of several annular corner angle mirrors
It penetrates and is spread in below spherical hollow space lens inner cavity on the circumferential surface of inner wall, because through the refraction diffusion of several wide corner angle side
Angle α≤45 ° that light and incidence surface are formed, and the extended line on the corner angle side intersects with spherical hollow space lens inner cavity bottom edge, institute
It will not be mapped to other than spherical hollow space lens inner cavity with light.Another short corner angle side is due to perpendicular to incidence surface, only seldom light
Line is reflected by short corner angle side, and the direction of refracted light is also below spherical hollow space lens inner cavity.
Finally by tertiary reflex optically focused, the light being diffused into below spherical hollow space lens inner cavity close to inner wall circumferential surface is few
It partially passes through under optically focused funnel direct projection to optically focused funnel on several cell pieces of mouth, most of light that spreads is through the reflective of optically focused funnel
Inner wall is one or many to be reflexed under optically focused funnel on several cell pieces of mouth.Optically focused funnel two sides form 30 ° -55 ° of folder
Angle ensure that multi-order refractive light is condensed on several cell pieces of mouth under funnel, realize efficient omnidirection Photospot solar
Power generation.
