Heater with hollow annular cylinder heat exchanger

Abstract

A heater with a hollow annular cylindrical heat exchanger, including a pot body, a layer of insulating material, a hollow fin ring, a heat preservation chamber, a combustion chamber, a fan, a hollow annular cylindrical heat exchanger and a smoke pipe, the combustion chamber is located The bottom of the pot body, the heat preservation chamber surrounds the outer wall of the pot body, and the heat insulation material layer is wrapped around the heat preservation chamber and the outside of the combustion chamber. Installed in the pot body, there is a communication opening between the bottom surface of the hollow annular cylinder heat exchanger and the bottom of the pot body, the bottom surface of the hollow annular cylinder heat exchanger communicates with the combustion chamber, and the lower end of the smoke pipe exchanges heat with the hollow annular cylinder The top surface of the pot is connected, and the multi-layer hollow fin ring is located on the inner wall of the pot. The setting of the hollow fin ring and the hollow annular cylinder heat exchanger does not affect the change of the water level in the pot, and there will be no accumulated water in the slit that is difficult to scoop out; the structure is simple, the heat transfer rate is fast, and time is saved; the combustion heat can be utilized High efficiency and obvious energy saving.

Description

technical field [0001] The invention relates to the field of stoves, in particular to a heater provided with a hollow annular cylinder heat exchanger. Background technique [0002] Gas stoves are widely used in household or catering fields. Burning natural gas has the advantages of no solid smoke and high heat. However, the combustion flame of the common gas stove is open outside the pot body, so the heat loss is large and the thermal efficiency is low. The material in the pot is heated only through the wall surface of the pot body, mainly the bottom surface, the contact time of the flame is short, and the heat exchange area is small. Contents of the invention [0003] The present invention aims at the deficiency of prior art, provides a kind of [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A heater provided with a hollow annular cylindrical heat exchanger, including a pot body, a layer of insulat...
