Through the above, when the heat exchanger is used for gas-gas heat exchange, liquid-liquid heat exchange or gas-liquid heat exchange, a cold source or a heat source can be led into the first heat exchange tube 1 from the first input tube 11, and correspondingly, the heat source or the cold source is led into the second heat exchange tube 2 from the second input tube 12, so that mutual conduction and exchange of heat are realized through the first heat exchange tube 1 and the second heat exchange tube 2 which are in contact with each other, the heat source is transferred to the cold source, the temperature of the heat source is reduced, and the recycling work of energy is realized; after the heat exchange is completed, the first heat exchange tube 1 will discharge the fluid from the first discharge tube 7 through the first pump body 6 connected by the first discharge joint 5, and the second heat exchange tube 2 will discharge another fluid from the second discharge tube 10 through the second pump body 7 connected by the second discharge joint 8; in order to better realize the heat exchange of the fluid in the first heat exchange tube 1 and the second heat exchange tube 2, the existence time of the fluid in the first heat exchange tube 1 and the second heat exchange tube 2 can be controlled by utilizing the opening and closing action of the ball seats 13 on the first ball valve 3 and the second ball valve 4, so that the sufficient exchange of a fluid heat source is realized, and the purpose of the sufficient heat exchange of the fluid is achieved.

Example one
