Abstract
The present invention relates to a kind of hexagon helical duct compact heat exchanger, which includes cold fluid internal channel, hot fluid internal channel, cold fluid distribution cavity, hot fluid distribution cavity, cold fluid outer tube and hot fluid outer tube.It is characterized by: cold fluid and hot fluid is exchanged heat using staggeredly positive triangle channels several in the middle part of heat exchanger, while torsion structure is improved heat exchange property in the middle part of heat exchanger.The compact heat exchanger is simple and reliable for structure, and heat exchange efficiency is high.
Description
Technical field
The invention belongs to technical field of heat exchange devices, are specifically related to a kind of high-efficiency compact heat exchanger.
Background technique
Heat exchanger is the equipment that the partial heat of hot fluid is passed to cold fluid with certain heat transfer type, also known as hot friendship
Parallel operation.The problem of heat exchanger has having been widely used in the industrial production, faces energy shortage due to our times, heat exchanger
There is increasingly important role.The requirement of heat exchanger be with good reliability, it is high-efficient, it is at low cost.
Heat exchanger can be divided into tubular type, board-like and special shape with heat-transfer area structure.The wherein main spy of pipe heat exchanger
Point is that structure is simple, cost is lower, selection range is wide, but its coefficient of heat transfer is not high, is not easy to clean.Plate-type heat-exchange utensil
There is the characteristics of heat-transfer intensity height, using flexible, manufacture handling ease, but its bearing capacity is lower, and leakage problem easily occurs,
Its operation temperature can not be excessively high simultaneously.
With the theoretical continuous development with mechanical technique, a good heat exchanger of various aspects of performance becomes urgent need.
Lower to solve current heat exchanger heat exchange efficiency, the larger problem of volume, the present invention proposes that a kind of hexagon helical duct is compact
Heat exchanger enhances heat exchange property by compact geometry designs and torsion structure, to obtain compared with previous heat exchanger higher
Heat exchange efficiency and smaller volume.
Summary of the invention
(1) technical problems to be solved
The purpose of the present invention is to provide a kind of hexagon helical duct compact heat exchanger, solve current heat exchanger volume compared with
Greatly, the low problem of heat exchange efficiency provides a kind of more efficient heat exchange mode for heat exchanger.
(2) technical solution
To solve the above problems, the present invention adopts the following technical scheme:
A kind of hexagon helical duct compact heat exchanger, which includes cold fluid internal channel, hot fluid internal channel, cold
Fluid distribution chamber, hot fluid distribution cavity, cold fluid outer tube and hot fluid outer tube, it is characterised in that: the internal channel is by handing over
The hexagonal channel that wrong multiple equilateral triangle passage aisles are constituted；Divide by the fluid of internal channel in the channel middle front part of distribution cavity
In diffusion type, flow path expands while rear portion of runner is spread；In hot fluid distribution cavity, passage portion is by triangle after cold fluid
Shape transition is circle, and in cold fluid distribution cavity, passage portion is circle by triangle transition after hot fluid；Heat exchanger internal channel
Spiral section is rotated by 360 °；Two fluid outer tubes are arranged in different directions；Total heat exchange area A and equilateral triangle side length a, equilateral triangle are total
The relational expression of port number n, the segment length l that exchanges heat are as follows:
(3) beneficial effect
The present invention has the beneficial effect that:
1. simple and reliable for structure；2. volume compact；3. heat exchange efficiency is high.

Fig. 3 is flow path cross-sectional view in the middle part of heat exchanger of the invention；
Fig. 4 is runner cross-sectional view in the middle part of heat exchanger of the invention；
In figure: 1. cold fluid outer tube, 2. cold fluid distribution cavity, 3. hot fluid outer tube, 4. hot fluid internal channel
5. 6. hot fluid outer tube of cold fluid internal channel, 7. hot fluid distribution cavity, 8. cold fluid outer tube
Specific embodiment
Below in conjunction with attached drawing, the present invention is described in further detail.
A kind of material of hexagon helical duct compact heat exchanger of the invention can use metal or nonmetallic materials.It is tight
Gather the course of work of heat exchanger are as follows: cold fluid enters heat exchanger from outer tube 1, enters in cold fluid after cold air distribution cavity 2 and leads to
Road 5 carries out heat by heat exchanger rotating middle part part and hot fluid internal channel 4 and exchanges, by supercooling fluid distribution chamber from cold
Fluid outer tube 8 is discharged.Meanwhile hot fluid enters heat exchanger from hot fluid outer tube 6, and hot-fluid is entered after superheated fluid distribution cavity 7
Internal channel 4, carries out heat in the middle part of heat exchanger with cold fluid and exchanges, by superheated fluid distribution cavity from hot fluid outer tube 3 into
Row discharge.Cold fluid and hot fluid completes heat exchange at this time.
The foregoing is merely a specific embodiment of the invention, and do not have to the limitation present invention, all in essence of the invention
Any modification, equivalent replacement, improvement and so within mind and principle, should all be included in the protection scope of the present invention.
