The invention discloses a gas preheating combined heat pipe exchanger, relating to the technical field of combined preheating systems used by hot-blast stoves of iron making blast furnaces. The gas preheating combined heat pipe exchanger comprises a first gas passage and a second gas passage arranged up and down; the lower bottom of the first gas passage and the upper bottom of the second gas passage are separated by an intermediate baffle plate; a first low-temperature gas inlet and a first high-temperate gas outlet are respectively arranged at the left and the right ends of the first gas passage; a second low-temperature gas outlet and a second high-temperate gas inlet are respectively arranged at the left and the right ends of the second gas passage; a plurality of heat pipes pass through the intermediate baffle plate by a sealing member; and the upper parts of the heat pipes are arranged in the first gas passage while the lower parts are arranged in the second gas passage. The heat-exchanged gas can be heated to 250-350 DEG C without using a gas two-stage preheating turbolator heat exchanger. Therefore, the energy saving and the emission reduction are achieved, the volume of the equipment is reduced, the metal consumption is decreased, and the manufacturing cost and the running cost are decreased.
