Heat collector divides two kinds, a kind of is the high temperature and high pressure steam type heat collector of major comonomer or several major comonomer assembly forms, another kind is a plurality of minor comonomer assemblys or the burnt band of dull and stereotyped many groups concentrating collector, and heat collector also can adopt large-scale vacuum tubular type or flat water heater formula; Adopt closed thermal-arrest loop, the evaporimeter of described loop circuit heat pipe is back-shaped pipe evaporator, the condenser of loop circuit heat pipe is the coil condenser, and two valves of liquid ingress pipe or boil-off gas delivery line will be dressed up triple valve and be convenient to working medium filling and vacuumize installation.

Among the present invention, all types heat collector all adopts high efficiency heat absorption backboard welding copper pipe, and adopts two-way loop return pipe, and tube wall can carry corresponding steam pressure.

Adopt such scheme, the present invention mainly contains following innovative point.

(1) concentrator adopts the utilizing line-focus Fresnel lens that ultra-clear glasses is produced, the lens focus type is linear, the several times that can obtain required multiple focus on light belt, light belt is more suitable for for the heat absorption metal tape, and burnt bandwidth is corresponding with the heat absorbing sheet width, also can directly impinge upon on the metal tube, but the pipe top layer to plate the high efficiency heat absorption layer by methods such as magnetron sputterings, focus on multiple and determined by lens light gathering area and light gathering efficiency sum of products heat absorption sheet metal or metal tube light-receiving area ratio.

Can obtain high power concentrator when (2) heat collector adopts major comonomer, produce high temperature and high pressure steam, be often referred to temperature at 200-800 ℃ of pressure at 6 more than the atmospheric pressure, the major comonomer assembly can obtain required quantity of steam, be fit to the solar energy in large area air-conditioning, the generating of Stirling external-combustion engine heat, the high temperature high steam application places such as steam drying room, and small-size flat can obtain low-concentration, warm low-pressure steam in the generation, be often referred to temperature at 100-200 ℃ of pressure at 6 below the atmospheric pressure, be fit to collective or domestic heating, solar airconditioning, the basic heat supplies such as constant temperature swimming pool.

(3) adopt closed thermal-arrest loop, the evaporimeter of described loop circuit heat pipe is back-shaped pipe evaporator, the condenser of loop circuit heat pipe is the coil condenser, and two valves of liquid ingress pipe or boil-off gas delivery line will be dressed up triple valve and be convenient to working medium filling and vacuumize installation.

(4) vacuum tube and metal tube in mouth of pipe exit and glass welding, adopt two outlets of plating molybdenum and to vacuumize with the glassy phase welding, and this is because molybdenum is identical with the vacuum tube glass coefficient of expansion.

In sum, the present invention is a kind of, and is simple and reliable for structure, with low cost, and installation and transportation are convenient, is easy to the high performance-price ratio basis heat collector in various middle high temperature heat utilization demands place.
