Description

Technical Field

[0001] This specification relates to the field of water heater technology, and in particular to a heat exchanger installation structure, a combustion heat exchange system, and a gas water heater. Background Technology

[0002] A gas water heater generally consists of a combustion device, combustion chamber, heat exchanger, fume hood, fan, gas pipeline, flue gas pipeline, inlet water pipeline, and outlet water pipeline. Gas and air mix and burn in the combustion chamber to form high-temperature flue gas. This high-temperature flue gas flows to the heat exchanger, where it exchanges heat with the water flowing within. After passing through the heat exchanger, the flue gas flows to the fume hood. Currently, the fume hood is fixed to the heat exchanger using flange bolts.

The back plate 123 is provided with first air-cooling holes, allowing gas to flow from the first air-cooling holes into the first air-cooling channel via upward exhaust, and then from the first air-cooling channel to the heat exchanger 103. A second air-cooling channel is formed between the second baffle and the cover plate 104 of the heat exchanger mounting structure 100. The cover plate 104 is provided with second air-cooling holes, allowing gas to flow from the second air-cooling holes into the second air-cooling channel via upward exhaust, and then from the second air-cooling channel to the heat exchanger 103. The first insulation cotton is connected to the first vertical plate 121 of the heat exchanger mounting structure 100. The second insulation cotton is connected to the second vertical plate 122 of the heat exchanger mounting structure 100. By setting up the baffles and insulation cotton, the temperature of the combustion chamber wall can be prevented from becoming too high, and the machine operating noise can also be reduced.
