Abstract
The utility model discloses a kind of electromagnetic heating tubes of effective increased thermal conductivity, specially shaftless screw piece is provided in the metallic conduit of electromagnetic heating tube, the metallic conduit is coaxially arranged with shaftless screw piece, the inner wall of the metallic conduit is to be fixedly connected with shaftless screw piece, and the screw pitch of the shaftless screw piece and the ratio of metallic conduit interior diameter are 2-3.5:1；The utility model increases the heat-conducting area of inner wall by the shaftless screw piece being arranged inside metallic conduit, realizes will not increase heat transfer efficiency under the premise of barrier liquid flowing, ensure that sufficient heat exchange, realize sufficient heat transfer；It is particularly suitable for the heating of high, poor fluidity the liquid of stickiness.
Description
Technical field
The utility model relates to a kind of electromagnetic heating tube, especially one kind can effective increased thermal conductivity, be suitable for stickiness
High, poor fluidity liquid electromagnetic heating tube.
Background technique
Currently known electromagnetic heating tube construction is by metallic conduit, coil rack, electromagnetic coil and skeleton fixed screw
Composition.Structure is that coil rack is fixed on metallic conduit with skeleton fixed screw, and electromagnetic coil is then wound into coil
On skeleton.When electromagnetic coil passes through high-frequency current, coil generates high frequency magnetic field, and metallic conduit generates whirlpool under high frequency magnetic field
Stream, to make metallic conduit fast heating, reaches to liquid heating effect in pipeline.But on the other hand it is this design there is also
Some problems, when metallic conduit diameter becomes larger, the limited area of iron core inner wall is only leaned in heat transfer, and heat transfer efficiency is low, Er Qieshui
It is to flow through iron core in parallel, only the surface of water and iron core carry out heat exchange, and heat exchange is insufficient.Cause tube wall temperature unstable or super
Temperature, temperature adjustment is frequent, and soak losses are big.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of electromagnetic heating tube of effective increased thermal conductivity.For
Reach above-mentioned purpose, the utility model is achieved by the following technical solution.
A kind of electromagnetic heating tube of effective increased thermal conductivity, electromagnetic coil are wrapped in the coil rack of metallic conduit outer wall
On, be provided with shaftless screw piece in the metallic conduit, the metallic conduit with shaftless screw piece be it is coaxially arranged, it is described
Inner wall and the shaftless screw piece of metallic conduit be to be fixedly connected, the screw pitch and metallic conduit interior diameter of the shaftless screw piece
Ratio be 2-3.5:1.
Preferably, the inner wall of the metallic conduit is mutually fixed by welding with shaftless screw piece.
Preferably, the ratio of the screw pitch of the shaftless screw piece and metallic conduit interior diameter is 2.5:1.
Preferably, shaftless screw piece annular surface area and the ratio of metallic conduit cross section are 1:1.5-2.
The utility model is generated compared with the existing technology to be had the beneficial effect that.
The utility model increases the heat-conducting area of inner wall by the shaftless screw piece being arranged inside metallic conduit, increases
Heat transfer efficiency, the certain proportion that screw pitch is formed with metallic conduit internal diameter realize will not barrier liquid flowing under the premise of realize
Optimal heat transfer efficiency.When liquid passes through the device, under the action of shaftless screw piece, liquid, which will form, to stream, with metal
Inner wall of the pipe comes into full contact with, and is had the opportunity to touch heat source by the various pieces for the liquid that flight is upset, and ensure that adequately
Heat exchange ensure that the abundant quick transmitting of heat, increase heat-conducting area, increase connecing for liquid and metal pipe internal wall
The time is touched, sufficient heat transfer is realized.The present apparatus is not related to water conservancy diversion axis or column, is more advantageous to the flowing of liquid and relies on simultaneously
Shaftless screw piece realizes the effect for increasing heat transfer efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 is metallic conduit, and 2 be shaftless screw piece.
Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, tie
Embodiment and attached drawing are closed, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein
It is only used to explain the utility model, is not used to limit the utility model.This is described in detail below with reference to examples and drawings
The technical solution of utility model, but the scope of protection is not limited by this.
As shown in Figure 1, a kind of electromagnetic heating tube of effective increased thermal conductivity, electromagnetic coil are wrapped in 1 outer wall of metallic conduit
Coil rack on, be provided with shaftless screw piece 2 in metallic conduit 1, metallic conduit 1 is coaxially arranged, gold with shaftless screw piece 2
The inner wall of metal conduit 1 is formed a fixed connection with shaftless screw piece 2 by welding, in the screw pitch and metallic conduit 1 of shaftless screw piece 2
The ratio of diameter is 2.5:1, and the ratio of shaftless screw piece annular surface area and metallic conduit cross section is 1.2:2.
The above content is the further descriptions done in conjunction with specific preferred embodiment to the utility model, cannot
Assert that specific embodiment of the present utility model is only limitted to this, for the utility model person of an ordinary skill in the technical field
For, under the premise of not departing from the utility model, several simple deduction or replace can also be made, all shall be regarded as belonging to
The utility model determines scope of patent protection by the claims submitted.
