1. A method for manufacturing an integrated thermal superconducting plate heat exchanger comprising:

a heat exchange plate with a composite plate structure comprising a middle plate, a first plate and a second plate, the first plate and the second plate are located on both sides of the middle plate respectively and are composited with the middle plate through a rolling process, a first projection structure is formed on the first plate and a second projection structure is formed on the second plate;

a thermal superconducting pipe formed between the first projection structure and the middle plate, the thermal superconducting pipe is an enclosed pipe and filled with a heat transfer working medium therein; and

a fluid pipe formed between the second projection structure and the middle plate, the fluid pipe has two end-openings for communicating with a fluid system to introduce fluid into therein;

providing three plates, one of the plates being used as the middle plate and other two plates being used as the first and second plates; performing roughening on a single face of the first and second plates and performing roughening on both faces of the middle plate;

defining, through printing, shapes of the fluid pipe and the thermal superconducting pipe on two roughening faces of the middle plate;

placing the first and second plates on two sides of the middle plate, the roughening faces of the first and second plates and the middle plate being bonded and aligned, and riveted along edges;

heating the riveted three plates to a certain temperature and maintaining for a period of time, then performing a hot rolling process to form the composite plate structure;

filling a high-pressure fluid to the composite plate structure until the composite plate structure is expanded, and forming the fluid pipe and the thermal superconducting pipe inside the composite plate structure while respectively forming the first projection structure and the second projection structure on two surfaces of the composite plate structure; and

filling the heat transfer working medium into the thermal superconducting pipe and sealing the thermal superconducting pipe.
