Abstract

The invention discloses a double-channel heat exchanger. The double-channel heat exchanger comprises a heat collector, first and second water boxes mounted at one end of the heat collector, and a third water box mounted at the other end of the heat collector; first and second main water pipes respectively communicating with the first and third water boxes by two ends, and third and fourth main water pipes respectively communicating with the second and third water boxes by two ends are mounted on the heat collector in parallel; first and second inner pipes of which the two ends respectively extend out of the first and third water boxes are respectively mounted in the first and second main water pipes; third and fourth inner pipes of which the two ends respectively extend out of the second and third water boxes are respectively mounted in the third and fourth main water pipes; one ends, extending out of the corresponding water boxes, of the inner pipes respectively communicate through connecting pipes; the cross sections of the main water pipes and the cross sections of the inner pipes are annular in shape; main pipe springs are arranged between the main water pipes and the corresponding inner pipes; and inner pipe springs are arranged on the inner walls of the inner pipes. The double-channel heat exchanger is convenient to machine, and is high in pass percent and heat efficiency, and the cost can be greatly reduced.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a double-channel heat exchanger. Background technique [0002] Energy saving and environmental protection are the primary issues that the gas appliance industry should consider. The existing dual-channel heat exchanger is mainly composed of a heat collector, water boxes installed at both ends of the heat collector, five or six oval main water pipes, and special-shaped inner pipes installed on the corresponding main water pipes. Domestic water is provided through the flow of various inner pipes, and heating water is provided by main water pipes. The consumption of copper is large, and the special-shaped inner tube is welded, which is inconvenient to process, the pass rate is low, and the thermal efficiency of the entire heat exchanger is low. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a dual-channel heat exch...
