The invention discloses a heat exchanger and in particular relates to a heat exchanger for exchanging heat with water through heat generated by gas combustion. The heat exchanger comprises a first heat exchange plate, a second heat exchange plate and air blocking pieces between the first heat exchange plate and the second heat exchange plate, wherein the first heat exchange plate and the second heat exchange plate are arranged in a mirror symmetry manner; S-shaped grooves running through the upper ends and the lower ends of the heat exchange plates are formed in the first heat exchange plate and the second heat exchange plate; the flat surfaces of the first heat exchange plate and the second heat exchange plate are fitted with each other and are welded to form a closed S-shaped channel; the air blocking pieces are arranged at the curves of the first heat exchange plate and the second heat exchange plate and adopt arc-shaped structures. According to the heat exchanger disclosed by the invention, pipe materials are replaced with metal plates, and a pipe cutting welding or pipe bending process is replaced with a stamping welding process, so that the heat exchanger has the characteristics of low production cost, high heat exchange efficiency, reliable structure, simplicity for manufacturing and stable quality.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to a heat exchanger for exchanging heat with water through the heat generated by gas combustion. Background technique [0002] Traditional gas water heaters, gas water boilers and gas steam generators generally use fire tube heat exchangers for heat exchange. At present, there are two methods for fire tube heat exchangers: one is to cut metal straight tubes into several small sections, and then arrange several small sections of metal pipes end to end to form an "S" shape, and finally weld them into shape. This production process Complicated, difficult to control quality and high manufacturing cost; the other is to directly bend a metal straight tube into an "S" shape through the bending process, but due to the limitation of the production process characteristics, the bending radius of the fire tube is large, and the fire tube replacement The thermal efficiency is low, and it is difficult to meet...
