Gas combustion heat exchanger

Abstract

The invention discloses a gas combustion heat exchanger. A combustion cavity is formed in the inner upper portion of a left heat exchange body. A smoke discharge through hole is formed in the top of aright heat exchange body. A total heat exchange channel which runs in a U shape is formed in the left heat exchange body, the right heat exchange body and a lower heat exchange body. A sinuous totalwater channel is formed in the walls of the left heat exchange body, the right heat exchange body and the lower heat exchange body. After fire burns in a combustion chamber, flowing water is heated bythe heat of the fire through the total heat exchange channel; and cold water enters a water inlet, exchanges heat with the water channel to absorb heat, then turns into hot water and flows out of a water outlet in the other end. The height of the heat exchanger is reduced, the normal use heat exchange efficiency can be reached, and the overall height is reduced when the heat exchanger is installed in a water heater. The heat exchanger is an uncoiled water pipe, the sinuous water channel is directly arranged in the bodies of the heat exchanger, heat is directly transferred through the bodies of the heat exchanger to heat water, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a water heater heat exchanger, in particular to a gas combustion heat exchanger. Background technique [0002] Existing water heater heat exchangers are all coiled water pipes in the heat exchanger. When the gas is burned to exchange heat, it first heats the body, then transfers heat to the water pipes through heat transfer, and then heats the water through heat transfer. The thermal efficiency is not high enough, and the heat energy consumption is large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coil-free water pipe, directly set the water channel in the heat exchanger body, heat the water directly through the heat exchanger body, improve the heat exchange efficiency, and the gas combustion heat exchange with the combined installation of components device. [0004] The solution to the above-mentioned technical problems is: [0005] A gas combustion heat ...
