Coiled pipe type heat exchange efficient heater

Abstract

A coiled pipe type heat exchange efficient heater comprises a pot body, a combustion chamber, a heat-preserving chamber, a heat-insulating material layer, a fan, a fuel gas combustion disk, a coiled pipe type smoke pipe and cross-like section hollow spiral fins; the combustion chamber is located at the bottom of the pot body; the heat-preserving chamber surrounds the outer side wall of the pot body; the heat-insulating material layer wraps the outer side of the heat-preserving chamber and the outer side of the combustion chamber; the fan is installed at the position of an opening in the lower end of the combustion chamber; the fuel gas combustion disk is located in the combustion chamber; one end of the coiled pipe type smoke pipe communicates with the combustion chamber; the other end of the coiled pipe type smoke pipe is higher than an opening in the upper end of the pot body; spiral structures of the cross-like section hollow spiral fins are consistent with the spiral structure of the coiled pipe type smoke pipe; first arms of the cross-like section hollow spiral fins communicate with the heat-preserving chamber; second arms of the cross-like section hollow spiral fins are closed and fixedly connected with the fixed coiled pipe type smoke pipe; and another two arms extend in the pot body in a closed manner. The coiled pipe type heat exchange efficient heater is simple in structure and high in heat transfer speed, and time is saved; and accumulated water which cannot be scooped out easily cannot be generated in slits; and the utilizing efficiency of combustion heat energy is high, and energy conservation is remarkable.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a coil-type heat exchange high-efficiency heater. 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] Aiming at the deficiencies of the prior art, the present invention provides a coil-type high-efficiency heat-exchanging heater so as to efficiently utilize the heat generated by gas combustion and save energy. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: ...
