Embodiment Construction
[0023] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.
[0024] The heat exchange device of the gas water heater proposed by the application, such as figure 1 As shown, it includes a number of heat exchange plates 11 arranged vertically, a number of burner plates 12 interleaved between the heat exchange plates 11, water inlet pipelines 13, water outlet pipelines 14 and gas pipelines 15; 11 are all communicated with water inlet pipeline 13 and water outlet pipeline 14; Several burner panels 12 are all communicated with gas pipeline 15.
[0025] It can be seen from the above that a number of heat exchange plates are arranged vertically, and a number of burner plates are interlaced between the heat exchange plates. The heat generated by the burner plates is transferred to the adjacent heat exchange plates through thermal radiation, and there is no other The heat transfer mediu...

The invention discloses a heat exchange device for a gas water heater and the gas water heater. The heat exchange device comprises a plurality of heat exchange plates which are vertically arranged, aplurality of burner plates which are arranged between the corresponding heat exchange plates in a staggering manner, a water inlet pipeline, a water outlet pipeline and a gas pipeline; a plurality ofheat exchange plates all communicate with the water inlet pipeline and the water outlet pipeline; and a plurality of burner plates all communicate with the gas pipeline. By adopting the heat exchangedevice for the gas water heater and the gas water heater, heat generated by the burner plates is transferred to adjacent heat exchange plates in a heat radiation manner without any other heat transfermedium between the burner plates and the corresponding heat exchange plates, so that the heat transfer efficiency between the burner plates and the corresponding heat exchange plates is high; and anarrangement mode of vertical arrangement of the burner plates accords with the principle that hot air rises, flue gas generated by the burner plates vertically rises, smoke exhaust is facilitated, heat exchange efficiency between the burner plates and the corresponding heat exchange plates can be improved, and the technical problem of low heat exchange efficiency of the existing gas water heater is solved.
Description
technical field [0001] The invention belongs to the technical field of gas water heaters, and in particular relates to a heat exchange device of a gas water heater and the gas water heater. Background technique [0002] A gas water heater refers to a gas appliance that uses gas as a fuel to transfer heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. [0003] The current gas water heater mainly adopts the atmospheric combustion method. In the combustion chamber, the burner nozzle sprays gas for combustion, and exchanges heat with the water in the heat exchanger through radiation and convection, resulting in large energy loss and low thermal efficiency. Contents of the invention [0004] The present application provides a gas water heater heat exchange device and a gas water heater, which solve the technical problem of low heat exchange efficiency of the existing gas water heaters. [0005] In order ...
