AI Technical Summary

Technical Problem

Existing liquid fuel water heaters have low heat exchange efficiency, and the rapid flow of heat energy leads to insufficient heat exchange efficiency in the integral heating cylinder.

Method used

Design a tubular liquid fuel water heater, which adopts a tubular heat exchanger in a closed heating water tank. The tubular tubes are evenly distributed around the heating inner cylinder. The combustion heating part of the combustion device is located in the heating inner cylinder. The heat energy is evenly distributed to the water body through the tubular tubes for heat exchange. Combined with annular flanges and heat insulation materials, heat loss is reduced.

Benefits of technology

It improves heat exchange efficiency, reduces heat loss, provides a normal temperature environment for easy installation of electrical components, has wide site applicability, low cost, and does not require the laying of natural gas pipelines.
