Support, complicated cost is high；2nd, heat collector has certain height, and security stability is poor, while to the outward appearance of building
Have a certain impact；3rd, heat collector uses non-concentrating structure, and collection thermal medium temperature is low, low in middle-temperature section collecting efficiency；4th, thermal-arrest
Device angle is not easy to adjust, and have impact on the annual solar energy heating efficiency of heat collector.
The content of the invention
A kind of the defects of it is an object of the invention to overcome above-mentioned existing associated solar heat collector, there is provided structure letter
List, cost are low, easy to install and maintenance, while solar thermal collector collecting efficiency is high, and heat-collecting temperature is high, do not influence the outer of building
See, the solar energy heat collector that reliability is high.
In order to solve the above technical problems, the technical scheme that this patent provides is：
Using a kind of adjustable bar shaped CPC heat collectors, including finned endothermic tube, CPC heat collectors housing, support elbow, connecting rod,
Main；Two mains and the finned endothermic tubes of Duo Gen are horizontal positioned and be mutually perpendicular to, the both ends connection support of finned endothermic tube
Elbow, support elbow are fixed on the top of main, CPC heat collector housings, CPC heat collector shells are cased with every finned endothermic tube
Body can surround finned endothermic tube and rotate, and multiple CPC heat collectors housings are connected by a connecting rod.
As a modification of the present invention, described finned endothermic tube includes endothermic tube and fin, and fin is stripe board,
It is fixedly attached to the both sides of endothermic tube, the selective absorber coatings of endothermic tube overlying.
As a modification of the present invention, described CPC heat collectors housing includes CPC reflectors, glass plate, shell on the back, end
Lid, connecting shaft；The front of CPC heat collector housings is glass plate, and the back side is shell on the back, and both ends are end cap；CPC reflectors are fixed on the back of the body
It is fixed on shell and positioned at the inside of CPC heat collectors, connecting shaft on a side end cap, connecting shaft is connected with link rotatable.
As a modification of the present invention, described adjustable bar shaped CPC heat collectors include the finned endothermic tube of 2-20 roots.
Relative to conventional art, heat collector provided by the invention has the advantage that：
1）The adjustable bar shaped CPC heat collectors use bar shaped heat collection unit, lightweight simple in construction, and then make using thermal-collecting tube
For the support of each heat collector unit, the complicated support of heat collector is eliminated, cost is low, easy to install；
2）The design of the adjustable bar shaped CPC heat collectors can close proximity to ground, windage is small, and security reliability is high, while does not influence
The outward appearance of building；
3）In order to ensure the temperature of medium in heat collector, it is necessary to increase focusing ratio, the design of CPC reflectors is employed；In order to subtract
The weight of few endothermic tube, employ the design of pipe with small pipe diameter endothermic tube；In order to increase the area of each bar shaped heat collection unit, thermal-arrest is reduced
The quantity of unit, and also to the size of CPC reflectors under high concentration ratio be avoided, using finned heat absorption tubular construction.Therefore
The design of finned endothermic tube+CPC heat collector housings both ensure that the heat-collecting temperature and collecting efficiency of heat collector, and subtract as far as possible
The volume and weight of heat collection unit is lacked；
4）The design of connecting rod is employed, the angular adjustment of each bar shaped heat collection unit, bar shaped thermal-arrest can be realized by pulling connecting rod
Unit carries out angular adjustment according to the position of the sun at different moments, ensure that the collecting efficiency of solar thermal collector；
5）The apparatus structure is simple, cost is low, easy to install and maintenance, while solar thermal collector collecting efficiency is high, heat-collecting temperature
Height, it is reliable and stable not influence outward appearance, the device of building, has promotion potential.
