Abstract
The utility model provides a screw type flue heat exchanger of which the structure consists of an outer heat exchanger and an inner heat exchanger, wherein, a smoke exhaust port is arranged on the outer heat exchanger; a furnace chamber port is arranged in the middle of the inner heat exchanger; the side part of the inner heat exchanger is provided with a smoke inlet; the space from the smoke inlet of the inner heat exchanger to the smoke exhaust port of outer heat exchanger is a screw-shaped flue; the screw-shaped flue is positioned between the inner heat exchanger and the outer heat exchanger; a heat exchange fin is arranged on the wall of the screw-shaped flue. Compared with the prior art, the utility model is characterized in reasonable design, simple structure, low cost, easy processing, convenient installation and use, high heat exchange efficiency, etc., thereby having very good popularizing and use value.
Description
1, technical field
The utility model relates to a kind of heat exchanger, specifically a kind of spiral flue heat exchanger.
2, technical background
Heat exchanger is widely used in the industrial production, though the kind of heat exchanger is a lot, coil pipe type, shell and tube, coiled or the like are arranged, the each have their own advantage of above-mentioned heat exchanger, but also have deficiency, low etc. as complex structure, cost height, heat exchanger effectiveness.
3, summary of the invention
The purpose of this utility model provide a kind of simple in structure, cost is low, the spiral flue heat exchanger that heat exchange efficiency is high.
The purpose of this utility model realizes in the following manner, is made up of external heat exchanger and interior heat exchanger, and the helical space between the interior external heat exchanger is a flue, and the heat absorption fin is set on the inwall of flue, is used for fully absorbing the heat of flue gas.External heat exchanger is positioned at the top of body of heater, and interior heat exchanger is positioned at the top of burner hearth, and the flue gas that comes out from the burner hearth helical form flue of flowing through is discharged from the exhaust opening that is located on the external heat exchanger, finishes the heat exchange of heat and interior external heat exchanger.
Accompanying drawing is the structural representation of spiral flue heat exchanger;
4, description of drawings
Explain below with reference to accompanying drawing screw type flue heat exchanger of the present utility model being done.
Screw type flue heat exchanger of the present utility model, as shown in drawings, its structure is by external heat exchanger 1 Consist of with interior heat exchanger 2, be provided with exhaust opening 3 on the external heat exchanger, the centre of interior heat exchanger is provided with stove Thorax mouth 8, limit section is provided with into mouth 7, advances mouth 7 to the smoke evacuation of external heat exchanger 1 from interior heat exchanger 2 The space is helical form flue 5 between mouthfuls 3, helical form flue 5 be positioned at heat exchanger 2 and external heat exchanger 1 it Between, be provided with heat exchange fin 6 on helical form flue 5 walls.
5, embodiment
Its processing and fabricating of spiral flue heat exchanger of the present utility model is very simple and convenient, makes by the steel plate welding processing shown in the by specification accompanying drawing.Processing technology is general rivet welding process technology.
The use of spiral flue heat exchanger of the present utility model is very simple and convenient, as long as the middle circular hole of interior heat exchanger is aimed at stockhole, flue gas after the fuel combustion comes out from stockhole, spiral flue in entering between the external heat exchanger, the exhaust opening discharge after heat and the heat exchange fin heat exchange from the external heat exchanger.
Spiral flue heat exchanger of the present utility model is compared with prior art, have reasonable in design, simple in structure, with low cost, be easy to characteristics such as processing, easy to install and heat exchanger effectiveness height, thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
