A kind of heat abstractor that is used for electric magnetic iron remover
Technical field
The present invention relates to a kind of heat abstractor that reduces the electric magnetic iron remover coil temperature.Specifically, relate to a kind of heat abstractor that is used for electric magnetic iron remover.
Background technology
Electric magnetic iron remover is that a kind of electromagnetic field that utilizes produces the equipment of powerful attraction with ferromagnetism impurity in the separation of material.The big multilevel installation of tramp iron separator, its coil plane is horizontal, so the radiator in the coil all is to insert from horizontal direction, tramp iron separator is when moving continuously, the temperature of solenoid can rise, and therefore must take cooling provision, otherwise temperature rise is too high, gently then magnetic field intensity descends, and is heavy then burn coil.
The cooling means of tramp iron separator coil mainly contains oil immersion cooling method, dry type cooling method at present, forced cooling method and natural cooling etc., and wherein oil immersion cooling method is pitch of the laps to be immersed in cool off in the oil, but long-time use can make deterioration of oil.The dry type cooling method is to open the louvre of a hollow in coil central authorities, in louvre, place cooling ring, place fin in coil periphery again, but the shortcoming of this cooling method is that cooling ring and air contact area are too little, its heat dispersion is poorer when being used for powerful coil.Its shortcoming of the cooling method of forced circulation wind is that system complex, noise are big, inhomogeneous cooling is even, reliability reaches dustproof weak effect.Thereby practical application is restricted; Natural cooling is that the method for adopt filling Heat Conduction Material is drawn heat from coil, and this method exists from defectives such as great, maintenance difficult.
Summary of the invention
Technical problem: the present invention overcomes technical problem and the deficiency that the various heat abstractors of electric magnetic iron remover in the prior art exist, and a kind of heat abstractor that is used for electric magnetic iron remover of simple in structure, good heat dissipation effect is provided.
Technical scheme: the technical solution used in the present invention is: this heat abstractor is made of with vertical condensation segment horizontal evaporation section, horizontally disposed evaporation section one end stretches between the interlayer of coil, the other end is connected on the vertical condensation segment that is positioned at the coil outside, the inner chamber that the inner chamber of described evaporation section has square hole, a condensation segment has the continuous square hole more than 1, forms the L type connector that profile sealing, an inner chamber are interconnected with evaporation section and condensation segment are fixing.
Concaveconvex structure is arranged in the left and right sides of described evaporation section, and evaporation section is spliced mutually; Single condensation segment at the width dimensions of stitching direction less than the width dimensions of single evaporation section in stitching direction.
Be provided with several ribs around the outer surface of described condensation segment, the capillary with the intracavity inter-connection of condensation segment is installed on the lower surface.
Beneficial effect: the advantage of the heat abstractor that is used for electric magnetic iron remover of the present invention is as follows:
(1) heat pipe of entire heat dissipation device and radiator consubstantiality have been eliminated the thermal chocking when heat pipe contacts with the radiator split in the prior art, have effectively increased inner chamber passage section and heat exchange area, have further reduced heat transfer resistance.
(2) concaveconvex structure of evaporation section both sides can splice the assembly of any size, makes things convenient for type selecting to install.
(3) the special profile design of condensation segment has effectively increased outside area of dissipation, improves cooling effect.
(4) condensation segment liquid relies on the self gravitation natural back flow, need not wick.
(5) compact conformation, it is little, easy for installation to conduct oneself with dignity.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As depicted in figs. 1 and 2, heat abstractor is made of with vertical condensation segment horizontal evaporation section, wherein horizontal segment stretches between the interlayer of coil 3, vertical section is positioned at by the outside of coil 3, horizontal segment is an evaporation section 1, vertical section is a condensation segment 2, two sections are all adopted custom-designed made from aluminium profile, the inner chamber that has square hole, a condensation segment 2 at the inner chamber of evaporation section 1 is opening square hole and can open the square hole that communicates continuously more than 1 also, evaporation section 1 and condensation segment 2 are fixed in the junction, form the L type connector that profile sealing, an inner chamber are interconnected.
As shown in Figure 3, evaporation section 1 both sides have the concaveconvex structure of same size, so that it is horizontally-spliced, inner chamber is a square hole, has both saved material, has increased inner chamber heat exchange area and flow section again.
As shown in Figure 4, around the outer surface of condensation segment 2 several ribs 5 are set, improve the inned coefficient and the fin efficiency of outer surface to greatest extent, the shape of the continuous square hole of inner surface increases surface area as far as possible on the basis that guarantees flow section.
The profile width of condensation segment 2 is slightly less than the profile width of evaporation section 1, so that evaporation section 1 condensation segment 2 when horizontally-spliced can not touch at Width.Evaporation section 1 and 2 two kinds of section bars of condensation segment are welded into L type radiator, its inner chamber are vacuumized the back inject low boiling point working medium, such radiator is called Horizontal heat pipe.
Number of ampere turns, exciting power according to tramp iron separator calculate required total heat dissipation capacity, determine quantity, physical dimension and the single heat pipe heat flux of required heat pipe again by coil plane, intercept the horizontal segment and the vertical section section bar of respective length on request, they are welded into shape as shown in Figure 2, two section bar inner chambers must be got through at intersection, other port of inner chamber must seal, capillary 4 is installed in the condensation segment lower end, fill again with low boiling point working medium after inner chamber vacuumized, promptly finish single heat pipe behind the sealing capillary 4 and make.
Its horizontal segment is spliced the back mutually to form the evaporation section plane that conforms to the coil plane size, and spliced each heat pipe vertical section is in same vertical plane.The heat that coil produces during tramp iron separator work directly imports heat pipe evaporator section 1 into, heated liquid vaporization back flows into condensation segment 2 rapidly in the evaporation section 1, because condensation segment 2 is subjected to the cooling of outer gas stream, its wall surface temperature is lower than evaporation section 1, the gas that flows to condensation segment 2 becomes liquid at the wall condensation heat, because condensation segment 2 inner chambers are higher than evaporation section 1 inner chamber, liquid relies on gravity reflux to evaporation section 1.The high thermal conductivity that this heat pipe utilizes fluid phase state to change, heat is passed to condensation segment 2 from heat pipe evaporator section 1, heat is dispersed in the environment by the radiating fin of heat pipe condenser section 2, so circulation, heat in the coil 3 constantly is passed in the environment, has reached the purpose of heat radiation, utilizes heat pipe condenser section 2 and evaporation section 1 potential difference to improve medium circulation speed simultaneously, and the high inned coefficient in the condensation radiating segment outside effectively reduces heat transfer resistance, the radiating effect of enhancing tramp iron separator.
