Abstract
The invention discloses an Archimedes heat exchanger, which relates to a heat exchange technology, in particular to a technology that flame heat energy generated in the burning process of combustible energy sources (such as coal, oil, combustible gas and the like) is converted into hot air by the technology, and can be widely applied to the technical fields of drying, heating and the like. Different from other prior arts in the technical field, the Archimedes heat exchanger is mainly characterized by overcoming the defects that a pipeline external heat type heat exchanger has low energy source utilization rate and a pipeline internal heat type heat exchanger is easy to block, and having the advantages of high air flow heating rate of the pipeline external heat type heat exchanger and high energy source utilization rate of the pipeline internal heat type heat exchanger at the same time. A flame flow channel and an air flow channel in the heat exchanger which realizes the technology are in the form of Archimedes spiral eddy, so that flame flow and air flow in the heat exchanger form overlapped laminar flow. The sections of a heating body and a heated body in the heat exchanger are rectangles, and the ratio of a long side to a short side can be enlarged, so that the tolerance area of the heating body and the heated body is increased.
Description
Technical field
The present invention relates to a kind of hot swapping, and the flame heat energy that produces when exactly exactly the flammable energy (as coal, oil, combustible gas etc.) being burnt converts thermal current to by present technique.Can be widely used in technical fields such as oven dry, heating.
Background technology
At present, the flame that produces when the flammable energy (as coal, oil, combustible gas etc.) burns converts in the heat transfer technology field (hereinafter all " flame that produces when the flammable energy burns converts the heat transfer process of thermal current to " being abbreviated as " air heat exchange " at this paper) of thermal current, usually people are called warm (heat) wind furnace or warm (heat) blower fan to the means that realize the air heat exchange, are divided into following form by the technology path of its realization and principle different:
1. the duct type pipeline divides external-heat and internal heat type.External-heat has been meant presses cold airflow to flow at pipe interior, and flame is at pipeline external heat pipeline, and heat conducts to flow air by inner-walls of duct, finishes heat transfer process, and advantage is an air stream quick heating.Its shortcoming is the quantity of heat exchanger tube and the restriction that length all is subjected to physical dimension, and the time that flame contacts with heat exchanger tube is shorter, and heat exchanger tube does not have the heat of the flame of adequate time extraction duct wall transmission, influences energy utilization rate.
Internal heat type is meant that flame flows and the heating heat exchanger tube in heat exchanger tube, have the cold airflow of pressure to carry out obtaining heat in the cooling procedure in exchange heat pipe outside, finishes heat transfer process.Its shortcoming be except on chat the external-heat shortcoming, also easily take place to be stopped up by flame tar in the heat exchanger tube.The relative external-heat of energy utilization rate is slightly high.
2. heat radiation type (being that wind is bathed formula) heat radiation type is meant that chamber wall adopts thermal conductivity material preferably, the design of outer wall of combustion chamber face has a lot of fin (similar radiator) or design that the heat pipe that penetrates chamber wall is arranged, when in the combustion chamber flame combustion being arranged, heating flame locular wall or burner hearth inner heat-conductive pipe, the heat energy that flame produces passes to fin or the outer heat pipe of burner hearth that the wall outside is decided in burning by chamber wall or heat pipe, have when pressing cold airflow heat pipe cooling off outside to fin or burner hearth, absorb and take away heat on sheet or the heat pipe, finish heat transfer process.Its shortcoming is that the heat carrier that is used for heat exchange is that the area of dissipation of fin or heat pipe heating surface area is all less relatively, and heat exchange efficiency is lower than duct type.
Summary of the invention
Flame circulation road and airflow path are the Archimedes spiral spiral vortex type in the heat exchanger of realization the technology of the present invention, make flame flow and the overlapping laminar flow of air stream formation in the heat exchanger.Heater and heated body cross section are rectangle in the heat exchanger, and long limit and minor face ratio are big arbitrarily.

The specific embodiment
The structure that the technology of the present invention is implemented is seen accompanying drawing 1, by the outlet flue 4 of critical piece, and thermal current outlet 7, outer cover of heat exchanger plate 9, heat exchanger internal partition 11, heat exchanger shell side plate 14 and pillar 10 are formed.
Solving the technical scheme that its technical problem adopts is: heat exchanger coverboard 9 and heat exchanger internal partition 11 all adopt the thin plate Heat Conduction Material, from basic point 12, outer cover of heat exchanger plate 9 and heat exchanger internal partition 11 both sides are connected with heat exchanger shell side plate 14 in the accompanying drawing 2 respectively, outer cover of heat exchanger plate 9 and heat exchanger internal partition 11 keep certain distance, in the appropriate location with pillar 10 support fixation, post is to parallel, form airflow path 8, spend when getting back to basic point 14 same horizontal planes from outer and inside turn 306 along the Archimedes spiral direction, continuation is along the precession of Archimedes spiral direction, and heat exchanger internal partition 11 and heat exchanger coverboard 9 form flame flow passage 6 and next layer of air circulation road.Heat exchanger coverboard 9 is connected with outlet flue along Archimedes spiral precession 1215 degree; Heat exchanger internal partition 11 is connected with outlet flue along Archimedes spiral precession 900 degree.Thermal current export 7 one ends and heat exchanger shell side plate 14 wherein 1 or two be connected, will export the 7 heat exchanger shell side plates 14 that are connected along circle perforates in the thermal current outlet 7 with thermal current, make heat exchanger cavity and thermal current export 7 and communicate.
The heat transfer process of realizing the technology of the present invention is: heat exchanger is placed burner 1 top, and the flame flow 5 that the flame that burner produces forms enters flame flow passage 6 from basic point 12 and discharges under the effect of air-introduced machine 16 until outlet flue 4 along the Archimedes spiral path flows.Air stream 3 enters airflow path 8 and flows out by thermal current outlet 7 until heat exchanger cavity 15 backs along the Archimedes spiral path flows under the effect of blower fan.
When flame flow 5 and air stream 3 flow in passage separately, the heat of flame flow 3 is by outer cover of heat exchanger plate 9,11 conduction of heat exchanger internal partition make air stream become thermal current when blower fan flow to heat exchanger cavity to air stream, finish whole air heat transfer process.
