Abstract
The utility model discloses a heat exchanger of a gas water heater. The heat exchanger comprises a box body. A smoke exhaust port is formed in the upper end of the box body. A condensate port is formed in the lower end of the box body. A smoke collection chamber and a heat exchange chamber are arranged in the box body. The smoke collection chamber is provided with a smoke inlet which is communicated with the smoke exhaust pipe of the gas water heater. The smoke collection chamber is divided into an upper smoke collection chamber and a lower smoke collection chamber through a smoke flow distribution plate. A water inlet is formed in the lower end of the heat exchange chamber. A water outlet is formed in the upper end of the heat exchange chamber. A plurality of heat exchange pipes are arranged in the heat exchange chamber. Smoke turbulence pieces are placed in the heat exchange pipes. The lower end of the lower smoke collection chamber is communicated with the lower end of the heat exchange chamber. The upper smoke collection chamber is communicated with the smoke exhaust port. Since the smoke collection chamber and the heat exchange chamber are arranged in the box body, smoke enters the heat exchange chamber from the smoke collection chamber and heat is exchanged through the heat exchange pipes in the heat exchange chamber. The heat exchanger of the gas water heater has the advantages of good heat exchange effect, simple structure, low cost and convenience in installation.
