The specific embodiment
With reference to accompanying drawing, concrete structure of the present invention is described in detail as follows:
Embodiment 1
As Figure 1-3, partly constitute by light-gathering tile and heat exchanger tube two; The external surface of light-gathering tile is an arch Merlon daylighting face 1, and the both sides of daylighting face 1 are provided with groove 2 downstream, the arranged outside engaging lug 3 of groove 2 downstream, and engaging lug 3 is provided with fixing hole 4.The inboard of light-gathering tile is provided with Fresnel lens, and each rib tooth 10 of Fresnel lens disturbs the thickness of side to be arranged to by two ends to center attenuation step by step; Aluminium matter heat exchanger tube 5 is arranged on the centre position, bottom of light-gathering tile; The inside pipe wall 8 of heat exchanger tube 5 is the sunken recess shape, between inside pipe wall 8 and the pipe outer wall 7 heat-transfer working medium cottonseed oil 9 is set, and pipe outer wall 7 is provided with insulation layer 6.
Embodiment 2
Described daylighting face 1 is arranged to planar shaped, and heat exchanger tube adopts copper embedding sequence blind pipe, and heat-transfer working medium adopts soya-bean oil, and other structure is with embodiment 1.
One, to focus on the longitudinal and transverse two directions tracking strategy as follows for the present invention's adaptive tracing of realizing not having tracking unit:
(1) vertical (north and south) is to skew
In the four seasons, the sun is as the criterion with equator (0 °), and the summer solstice sun is moved northward 23.5 °, and winter solstice south is moved 23.5 °.Static light-gathering tile will reach to make and day come up light positive to incident on the ground, should be synchronously and the certain inclination angle, north-south of horizontal plane maintenance.Its value every day is latitude and deviation angle sum, as, this day of winter solstice, the inclination angle of the Shenyang light-gathering tile that north latitude is 41.8 ° is:
41.8°+23.5°＝65.3°
It is the extreme value in whole winter that sun south is moved 23.5 °, determines the inclination angle if get its median (23.5 °/2=11.75 °) for the basis, will make light-gathering tile whole each day in winter sunlight all be similar to forward entrance.Inclination angle as Shenyang is:
41.8°+11.75°＝53.55°
This routine light-gathering tile is a warming, and the inclination angle, north-south is decided to be 53.55 ° of calculated values approximately.
The inclination angle towards the south on " people " font roof of tradition house (principal rooms) also tends to or near calculated value.So the present invention can directly prolong the inclination angle of using or changing this type of former scheme structure in room a little.
Exist deviation at agreement or actual inclination angle apart from theoretic inclination angle, light-gathering tile adopts line focus, and is not harsh to north-south angular deflection requirement, to adapt to.
Adapt to vertical misalignment with fixed angle.
(2) horizontal (thing) is to deflection
East rose the west and fell sun every day, deflect from 0 °-180 °, sunlight to watt angle of incidence also change thereupon, must realize accurately following the tracks of focusing.
This example is carried out particular design by each the rib tooth to Fresnel lens and is solved.
Angle of incidence is also made adaptations through watt folding light thereupon in changing continuously, finally focus on and give fixed position, replaces additional tracking unit to reach tracking with the planform of static state, and this example claims the static focusing of following the tracks of.
Like this, realize continuing to converge out striation in one day, thermal source is provided.
Striation center maximum temperature can reach 1000 ℃, for heat transfer efficient and terminal high temperature lay the foundation.
Two, the present invention gets heat with working medium and mostly is target most, heat as shown in the formula:
Q＝K.A.ΔT
As seen, the heat that receives of working medium and thermal transmittance, heat exchange area, execute that three variablees of the temperature difference are directly proportional between hot body and heated body.The algorithm that improves three variate-values is as follows:
Δ T (temperature difference): striation transfers thermal history striation and inside pipe wall, inside pipe wall and two heat transfer links of working medium of working medium to through inside pipe wall, and the former executes hot body in each link, and the latter is a heated body, and inside pipe wall is a public interface.The temperature of striation reaches as high as 1000 ℃, with flow in the working medium temperature difference big (Δ T ↑), it is many that working medium obtains heat energy, i.e. the heat exchange efficiency height.
A (heat exchange area): inside pipe wall is the sunken recess shape, and groove will fall into the striation heat absorption., surround groove and be mostly working medium to unofficial biography from tube hub, be equivalent to strengthen heat exchange area (A ↑).
K (thermal transmittance): inside pipe wall need be fast from the striation heat absorption as the public interface of two heat transfer links, and the heat that is drawn onto is also wanted fast to what working medium was put. and therefore, groove adopts big copper or the aluminum of thermal transmittance, to improve heat exchanger effectiveness (K ↑).
Resultant effect makes working medium get hot many (Q ↑), high efficient heat exchanging, and the working medium temperature can reach 500 ℃.
Three, material and can expand daylighting face provides the terminal thermal energy
Solar constant (sun vertical incidence power on the atmosphere) is about 1367 watts/square metre.
Ground is subjected to factor affecting such as latitude, season, time and air quality, much smaller than solar constant.As, Shenyang fine vertical incidence power in winter is about 550 watts/square metre.
