The invention discloses an air duct assembly, a heat exchange structure and a gas water heater. The air duct assembly includes a housing and auxiliary parts. The housing is provided with an installation part for installing the heat exchange assembly. The housing is provided with an air inlet duct and an air outlet. The air inlet and outlet are located on both sides of the installation part. There is a circulation pipeline in the auxiliary part. The circulation pipeline is connected to the air inlet and outlet. The circulation pipeline is used to guide the airflow in the outlet into the air duct. The circulation pipeline can re-introduce the airflow in the air outlet channel into the air inlet channel, so that the hot air in the air outlet channel whose temperature drops can be exchanged by the heat exchange component again, thus preventing the heat loss caused by the direct discharge of the hot air in the air outlet channel. The heat input is increased, so the above-mentioned air duct assembly can improve thermal efficiency while only using one heat exchange assembly, thereby achieving the effect of improving thermal efficiency while ensuring economy.
Description
technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to an air duct assembly, a heat exchange structure and a gas water heater. Background technique [0002] Traditional gas water heaters can be divided into non-condensing machines and condensing machines according to the exhaust state of the flue gas. The heat exchanger of the non-condensing machine has only one stage. It still contains more heat, so the energy utilization rate of this model is low, and the pollution to the environment is relatively large. In order to make better use of the waste heat of the flue gas, people have developed a condenser. The principle is to use two heat exchangers to perform secondary heat exchange on the flue gas. After the high-temperature flue gas passes through the two-stage heat exchangers, the heat is greatly absorbed, resulting in smoke The water vapor in the air condenses to form condensed water. This gas water heater has extre...
