Traditional flat plate collector plate cored structure is as shown in Figure 3: two ends are collecting pipe (32) longitudinally, collecting pipe one end is working media flow export (35) by plug (34) the sealing other end, another root collecting pipe one end is working media inflow entrance (36) by plug (34) the sealing other end, the centre is horizontal grid type thermal-arrest runner (33), and grid type thermal-arrest runner and collecting pipe are that metallic conduit, the grid type thermal-arrest runner of mutual UNICOM is welded on thermal-arrest film (31) back side.The heat that the front of thermal-arrest film absorbs solar energy directly passes to the thermal-arrest runner that is welded on the back side, has heated the water in the water tank thereby the working media that is full of in the thermal-arrest runner is heated, just be brought to heat(ing) coil by working media circulation heat.

The vacuum heat-pipe solar thermal collector is compared attractive in appearance inadequately with flat-plate solar collector, the vacuum heat-pipe heat collector also can't merge with building is perfect.

The shortcoming of traditional flat plate collector: system complex, cost height, indirect heat exchange efficient is low; Working media has volatility, must often safeguard and replenish the operation and maintenance cost height.

Summary of the invention

Invention of the present utility model be in order to overcome the shortcoming in the above-mentioned background technology, to provide a kind of simple in structure, the superconducting flat type plate core of solar heat-collecting that no working media and thermal conversion efficiency are high.

In order to realize the foregoing invention purpose, the utility model provides a kind of superconducting flat type plate core of solar heat-collecting, its technical scheme is: comprise the thermal-arrest film, also include horizontal super heat-conductive pipe, super heat-conductive pipe evaporation ends and the welding of thermal-arrest film, super heat-conductive pipe condensation end and vertical heat exchanger tube surface soldered are filled with recirculated water in the heat exchanger tube, heat exchanger tube is by drawing outer pipeline and water tank UNICOM.
