Abstract

The invention relates to a heat exchanger with an anti-corrosion structure, the heat exchanger comprises a copper shell, a copper heat exchange tube positioned in the shell, and a copper water inlet pipe and a copper water outlet pipe which are positioned outside the shell and are communicated with the heat exchange tube, and further comprises a flexible electronic anode and an anode controller. The flexible electronic anode extends into the heat exchange tube and is matched with the heat exchange tube in length and bending shape, one end of the flexible electronic anode extends out of the heat exchange tube and is connected with the positive electrode end of the anode controller, and the negative electrode end of the anode controller is connected with the outer wall of the heat exchange tube. The part, located in the heat exchange tube, of the flexible electronic anode is provided with a structure in which limiting insulation sections and exposed coating sections alternately appear in the length direction, and the limiting insulation sections can prevent the electronic anode from making contact with the inner wall of the heat exchange tube. The heat exchanger has the advantages that the flexible electronic anode extends into the bent and coiled heat exchange tube and the water inlet and outlet tube, electrons are excited through the exposed coating sections of the electronic anode, and the heat exchange tube and the water inlet and outlet tube are prevented from being corroded.

Description

technical field [0001] The invention relates to the anti-corrosion field of gas water heaters, in particular to a heat exchanger with an anti-corrosion structure and a gas water heater. Background technique [0002] The heat exchanger of a gas water heater is a component that transfers the heat of gas combustion to the water in the pipeline. It usually consists of a water inlet pipe, a straight heat exchange pipe, a connecting elbow and a water outlet pipe connected in series to form a water flow channel. The heat fins, heat exchange straight tubes and heat exchange fins are located inside the copper heat exchanger shell and are directly fired and heated by the burner. The outlet pipe is usually coiled several times outside the copper heat exchanger shell The bottom stretches out to form a hot water outlet. [0003] In the prior art, since the heat exchanger of the gas water heater is made of relatively thin copper tubes to form the water flow channel, effective anti-corros...
