Multifunction flat plate heat exchanger

A multifunction flat plate heat exchanger, comprising:

• two heat exchanging flat plates, each of the two heat exchanging flat plates has a first plate surface and a second plate surface opposite to each other, and a pipe tunnel located between the first plate surface and the second plate surface, the pipe tunnel of each of the two heat exchanging flat plates is configured to allow a heat-conductive medium to flow therein, the two heat exchanging flat plates being pivoted to each other, the two first plate surfaces being arranged in parallel to each other and flushed with each other in an unfolded state, the two first plate surfaces face each other and are overlapped with each other in a folded state;
• two spectrum selectivity absorption layers, respectively covering the two first plate surfaces;
• two light transmissive layers, respectively covering the two spectrum selectivity absorption layers, wherein each of the two light transmissive layers and the corresponding first plate surface are respectively located at two opposite sides of the corresponding spectrum selectivity absorption layer;
• two heat-conductive structures, respectively disposed on the two second plate surfaces, each of the two heat-conductive structures defining at least one flow path with the second plate surface of the corresponding heat exchanging flat plate and has a plurality of through holes communicated with the at least one flow path;
• and
• at least two airflow driving devices, one of the at least two airflow driving devices is disposed at one side of one of the two heat exchanging flat plates and one of the heat-conductive structures, the other one of the at least two airflow driving devices is disposed at one side of the other one of the two heat exchanging flat plates and the other one of the two heat-conductive structures, the at least two airflow driving devices are respectively disposed corresponding to the at least two flow paths, and each of the at least two airflow driving devices is configured to drive outside air to flow into the corresponding at least one flow path or drive air inside the corresponding at least one flow path to be exhausted to an outside.
