Abstract

The invention discloses a water heater heat exchanger which comprises a water inlet tube, a water outlet tube, a first group of communicating tubes, a second group of communicating tubes and a heat exchange main body which comprises a combustor, heat conduction tubes and a heat exchange fin which are formed by integral die-casting forming through aluminum alloy, three or more heat conduction tubes are arranged, and each heat conduction tube protrudes out of the first end and the second end of the heat exchange main body; the first group of communicating tubes and the water inlet tube are located at the first end of the heat exchange main body, the water inlet tube is used for being communicated with one heat conduction tube which protrudes out of the first end of the heat exchange main body, and the first group of communicating tubes is used for being communicated with the rest heat conduction tubes which protrude out of the first end of the heat exchange main body; the second group of communicating tubes and the water outlet tube are located at the second end of the heat exchange main body, the water outlet tube is used for being communicated with one heat conduction tube which protrudes out of the first end of the heat exchange main body, and the second group of communicating tubes is used for being communicated with the rest heat conduction tubes which protrude out of the first end of the heat exchange main body. The invention further discloses a manufacturing method of the water heater heat exchanger. The water heater heat exchanger and the manufacturing method thereof have the advantages that the cost is reduced, and the overall strength and the heat conduction efficiency of the heat exchanger are improved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater heat exchanger and a manufacturing method thereof. Background technique [0002] The heat exchange structure of the existing gas water heater heat exchanger is made of copper heat pipes interspersed in the fins, but the production cost of copper is relatively high, so people start to use aluminum alloy with low cost for production. However, the production of existing heat exchangers needs to wear some fins on the heat conduction tubes, and arrange coiled tubes around the combustion chamber, which not only has low efficiency, but also produces aluminum alloy heat exchangers with low strength. Contents of the invention [0003] The main purpose of the present invention is to provide a water heater heat exchanger and a manufacturing method thereof, aiming at saving costs and improving the strength of the water heater heat exchanger. [0004] In order to achie...
