Problems solved by technology

[0002] At present, the heat-absorbing plate cores commonly used in the field of flat-panel solar collectors are basically composed of strips or whole plates welded with upper runners. The limited heat conduction efficiency is not very high, so that the heat exchange efficiency between the flow channel and the water tank is not high, so that the superiority of the flat solar collector cannot be better displayed
On the other hand, the heat of the flow channel is conducted by connecting the heat-absorbing plate core with the superconducting heat pipe through welding or integral crimping, but since the heat pipe is indirectly transferred to the main channel through heat conduction, indirect conduction is bound to produce thermal resistance, so heat conduction The speed is slower, the efficiency is relatively poor, and the heat absorption of the heat-absorbing plate core is reduced
Due to the above two reasons, the heat collectors using the prior art have the following disadvantages: 1. The heat collection rate is slow and the heat transfer efficiency is not high; 2. The heat dissipation loss is relatively large in the heat conduction process; 3. The production The cost is too high; 4. The combination is not firm; 5. Poor frost resistance
