[0002] At present, the flue gas flow direction of the commonly used secondary heat exchanger flows from the bottom to the top of the heat exchanger, while the condensed water needs to flow downward due to the influence of gravity , the flow direction of condensed water in the heat exchange process is just opposite to the direction of smoke exhaust, which may easily cause condensed water to block the condenser, and CO discharge exceeds the standard, seriously affecting the safety of users
There is no condensate water seal device in the existing heat exchanger, and it is often necessary to add an independent part inside the product to realize the function of water seal, which requires a large number of seals, complex structure and low reliability

The invention discloses a gas water heater assembly and a heat exchanger. The heat exchanger comprises a connecting box, the heat exchanging assembly and an upper cover assembly. The top of the connecting box is provided with an opening, the connecting box structurally comprises a gas incoming cavity, a heat exchanging cavity and an exhausting cavity, the connecting box is provided with a gas inlet communicated with the air incoming cavity and a water drainage port communicated with the bottom of the heat exchanging cavity, and the bottom of the heat exchanging cavity is communicated with that of the exhausting cavity; the heat exchanging assembly is arranged in the heat exchanging cavity; the upper cover assembly covers the connecting box and comprises an exhausting channel and an upper cover arranged adjacent to the exhausting channel, the exhausting channel is communicated with the exhausting cavity, the upper cover covers the gas incoming cavity and the heat exchanging cavity so as to communicate with the same. The heat exchanger is simple in structure, the smoke flows from top to bottom in the heat exchanging cavity, the flowing direction of the smoke is the same as the dropping direction of condensate water condensed on the inner wall of the heat exchanging wall and outer surface of the heat exchanging assembly, and the condensate water is prevented from blocking the heat exchanger.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas water heater assembly and a heat exchanger. Background technique [0002] At present, the flue gas flow direction of the commonly used secondary heat exchanger flows from the bottom to the top of the heat exchanger, while the condensed water needs to flow downward due to the influence of gravity. On the contrary, it is easy to cause condensed water to block the condenser, and CO discharge exceeds the standard, which seriously affects the safety of users. There is no condensate water seal device in the existing heat exchanger, and it is often necessary to add an independent part inside the product to realize the function of water seal, which requires a large number of seals, complex structure and low reliability. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certai...
