A water heater combustion chamber based on high thermal emissivity coating

Abstract

The invention discloses a water heater combustion chamber based on a coating with high thermal radiation coefficient, comprising a combustion chamber main body, a heat exchange structure, and a heat radiation utilization structure; the combustion chamber main body includes an inner shell and an outer shell, and the inner shell is provided with a combustion chamber cavity body, the heat exchange structure includes heat exchange plates distributed in a spiral structure centered on the central axis of the combustion chamber cavity, the inside of the heat exchange plate is provided with air circulation channels, and the surface of the heat exchange plate is provided with several air channels. The nozzle, the heat exchange fin, the diversion hole and the burner; the heat radiation utilization structure includes a plurality of positioning brackets, a heat transfer medium pipe and a plurality of heat radiation reflectors located in the annular channel. The combustion chamber of the invention can fully contact the gas and air, and has the advantages of sufficient gas combustion, high utilization rate of heat energy, and safety and environmental protection.

Description

Technical field[0001]The present invention belongs to the technical field of heat exchanger, and in particular to a water heater combustion chamber based on a high thermal radiant coefficient coating.Background technique[0002]The water heater combustion chamber is a thermal energy that can be converted into a practical value. The structural design of the combustion chamber is generally considered to directly affect the heat exchange efficiency of the heat exchanger, so the structural design of the combustion chamber is also more and more important.[0003]The current water heater combustion chamber usually uses four metal plates to form a four-sided combustible chamber, and combustion pipes on the outer casing of the combustion chamber, and the heat is transferred to the water pipe after absorbing heat with the housing. Water, thereby completing heat exchange.[0004]Or, for example, the disclosure of which is an open number of CN203215979U, a heat exchange combustion chamber, including...

AI Technical Summary

Problems solved by technology

[0005] However, the above two combustion chambers have the following disadvantages. The internal structure design of the combustion chamber is unreasonable, so that the combustion of the gas is not sufficient, the heat will be directly dissipated into the air, and the loss of heat energy will greatly reduce the heat exchange efficiency of the heat exchanger and increase Energy consumption and gas supply
