Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 to Figure 3, the inner core 200 that this pipe heating device comprises heating pipe 100 and is installed in heating pipe 100, inner core 200 offers guiding gutter.
The shape of above-mentioned inner core 200 is cylindric and inner core 200 is arranged in heating pipe 100, in the process of this pipe heating device work, inner core 200 can produce a large amount of heat and make to there is high-temperature area around inner core 200, higher temperature can to the dielectric heating between inner core 200 and heating pipe 100, inner core 200 is arranged in heating pipe 100 to compare and is arranged at outside heating pipe 100 with inner core 200, ensure that inner core 200 can fully contact with medium thus improve the heat transfer efficiency between inner core 200 and medium, avoid the loss of the heat that inner core 200 produces, improve the efficiency of heating surface of inner core 200, simultaneously scald in order to avoid higher temperature causes heating pipe 100 inwall and affect the generation of the phenomenon in heating pipe 100 working life, the inwall of inner core 200 inner core 200 and heating pipe 100 when being arranged in heating pipe 100 away from.
The setting of above-mentioned guiding gutter 210 slow down the flow velocity of medium in heating pipe 100, be compared to medium directly by heating pipe 100, the setting of guiding gutter 210 makes certain media can flow along guiding gutter 210 in guiding gutter 210, and due to the distribution arrangement of guiding gutter 210 and the axial direction of inner core 200 not parallel, in guiding gutter 210, the flow direction of medium is not identical with the flow direction of medium between heating pipe 100 and inner core 200, certain media in the process of media flow in guiding gutter 210 can depart from the medium of guiding gutter 210 around inner core 200 and form interflow, but because the flow direction of medium in guiding gutter 210 is different from flowing to of inner core 200 environment, thus can upset MEDIA FLOW around inner core 200 to, make medium in heating pipe 100, occur the phenomenon of turbulent flow, reduce the flow velocity of medium in heating pipe 100, add the time of the delay of medium in heating pipe 100, medium is fully heated and improves the heating effect of pipe heating device.
Preferably, above-mentioned guiding gutter 210 is arranged on inner core 200 in the shape of a spiral, and the axial length of guiding gutter 210 is less than or equal to the axial length of inner core 200, when medium is by heating pipe 100, certain media in guiding gutter 210 can flow along guiding gutter 210, because guiding gutter 210 spiral is arranged, the medium in guiding gutter 210 is made to be more prone under the influence of centrifugal force depart from guiding gutter 210 and formed collaborate with the medium around inner core 200, flow to due to medium the phenomenon that inconsistent meeting causes medium turbulent flow in the process at interflow, thus create a further reduction the flow velocity of medium in heating pipe 100, medium fully can be heated in heating pipe 100.
Further, the quantity of guiding gutter 210 is two, but the quantity of guiding gutter 210 is not limited to two, can be three even more, article two, the setting of guiding gutter 210 expands the volume of medium in guiding gutter 210, add the area of contact of medium and inner core 200, the setting being compared to wall scroll guiding gutter 210 improves the efficiency of heating surface of inner core 200, the medium departed from around guiding gutter 210 and inner core 200 under the influence of centrifugal force that adds of two guiding gutters 210 forms the volume collaborated simultaneously, thus slow down the flow velocity of inner core 200 environment further, add the holdup time of medium in heating pipe 100, improve the heating effect of heating pipe 100.
Above-mentioned two guiding gutters 210 all in the shape of a spiral and be crisscross arranged on inner core 200, and the spacing of adjacent two guiding gutter 210 intersections is equal, make medium in two guiding gutters 210 in flow process, not only comprise and depart from guiding gutter 210 owing to being subject to centrifugal force and collaborate with the medium around inner core 200, and also constantly to conflux in the intersection of two guiding gutters 210 and produce collision and medium that certain media is departed from around guiding gutter 210 and inner core 200 collaborates, thus the medium added in two guiding gutters 210 departs from the probability of guiding gutter 210, make the medium in guiding gutter 210 be more prone to depart from the medium of guiding gutter 210 around inner core 200 and form interflow, thus slow down the flow velocity of medium influence inner core 200 environment in guiding gutter 210 further, add the holdup time of medium in heating pipe 100 thus improve the heating effect of inner core 200.
Because metallic material has good thermal conductivity, structural stability, the advantage of long service life, thus the heating pipe 100 of this pipe heating device and inner core 200 all adopt metallic material, and the winding of heating pipe 100 outer surface is provided with coil 400, the setting of coil 400 ensure that inner core 200 and heating pipe 100 can obtain rapid heating under the mode of induction heating, thus heat can be passed to medium between the two by inner core 200 and heating pipe 100, inner core 200 and both heating pipes 100 are both heating and decrease the time of dielectric heating to identical temperature, improve the efficiency of heating surface of medium, the setting of coil 400 simultaneously also assures that the circumferential temperature of both inner core 200 and heating pipe 100 and axial temperature are uniformly distributed, thus inner core 200 and heating pipe 100 can to homogeneous media heating between the two, improve the heating effect of inner core 200, avoid the generation causing the non-uniform temperature phenomenon of medium due to inner core 200 local heating.
The internal surface of heating pipe 100 is provided with coating 300, coating 300 has quick heating, to lower the temperature slow effect, thus in the process of this pipe heating device work, the conduction of heat that the setting of coating 300 decreases due to heating pipe 100 makes the air outside heating pipe 100 and the medium generation heat exchange institute dispersed heat in heating pipe 100, the medium shortened in heating pipe 100 is warming up to the time of identical temperature, improve the efficiency of heating surface of heating pipe 100, the setting of coating 300 simultaneously also can slow down the time that heating pipe 100 is cooled to identical temperature, improve the heat insulation effect of heating pipe 100.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
