The present invention is according to the operating temperature 160 DEG C ~ 250 DEG C of POLYAMIDE YARNS elasticizer to hot case, the requirement of Si Daonei maximum temperature difference value≤± 1 DEG C, according to the principle of gravity type heat pipe, in conjunction with POLYAMIDE YARNS texturing craft and device layout requirement, redesign hot box structure, select suitable conduction oil, make heat medium more reasonable at hot case Inner eycle, make heating guide rail Si Daonei maximum temperature difference value≤± 1 DEG C, the hot case of this structure of theory calculate can steady operation more than 3 years, the current actual tracing detection result of a year is: heating guide rail Si Daonei maximum temperature difference value≤± 1 DEG C, there is not heating guide rail silk channel temp wave phenomenon, there is not the phenomenon that hot case does not start in use for some time, when 250 DEG C of work, internal pressure is only 0.86x105Pa.
The tactic pattern that hot case overall structure of the present invention is taked " three rails, six ingots, three pipes ", that is: three heating guide rails, each heating guide rail has two rhizoid roads, whole hot case You Liugesi road (six ingots), lower box is evaporation tube, and in-built electrical bar heating, by RTD detected temperatures, casing top is condenser pipe, is connected between condenser pipe with evaporation tube by a liquid back pipe.Each part adopts and is welded to connect, and ensures the compactness (i.e. leak rate≤1.333X10-6Pa*l/s) of weld seam.In the junction of heating guide rail and condenser pipe, design a flow controller, the diameter of restriction is preferably 3.5mm.
The present invention is hot, and case is in working order, condenser pipe is upper, evaporation tube under, according to gravity type heat pipe principle, conduction oil is vaporized under the heating of electrical bar, first steam be full of heating guide rail, under the effect of flow controller, a pressure differential is produced in heating guide rail chamber and condenser pipe, steam is ejected in condenser pipe by restriction, steam condenses into liquid in condenser pipe, evaporation tube is back under gravity by liquid back pipe, complete a circulation, so move in circles and make heating guide rail interior point homogeneous temperature, due to the light-wall pipe that heating guide rail is wall thickness 1.5mm, its hull-skin temperature is consistent with cavity temperature, thus ensure the uniformity of heating guide rail Si Daonei temperature, maximum temperature difference value≤± 1 DEG C.
The present invention adopts mode of heating to be vented hot case, and structural design two blast pipes are for discharging the incoagulable gas of hot case inside.Concrete operations are: by the heating of hot case and temperature control to 270 DEG C, now hot case internal pressure is greater than an atmospheric pressure, cuts copper pipe and is discharged by the incoagulable gas of hot case inside, and then with silver brazing sealing, not only having ensured can not suction gas but also the ensure compactness of sealing.
The present invention compared with prior art has following beneficial effect: owing to devising flow controller, ensure that heating guide rail inside is full of steam, and hot case steam inside is able to forced circulation, even if in use having a small amount of incoagulable gas to produce also can only accumulate in condenser pipe, heating guide rail non-uniform temperature can not be caused, greatly can extend the normal service time of hot case like this; Select TherminolVP-1 or DOWTHERMA type conduction oil, when 250 DEG C of work, hot case internal pressure is only 0.86x10
5pa, security improves greatly; Employing electrical bar is directly immersed in the mode of heating in conduction oil, and temperature control is sensitiveer, and temperature-controlled precision is higher; The version of " three rails, six ingots ", effectively reduces hot case weight, is more convenient for manufacturing and installing, and in addition, when hot case breaks down, only has 6 ingots to quit work, can reduce the loss of user to greatest extent; Adopt mode of heating to carry out hot case exhaust, can avoid vacuumizing the easy suction gas of mode at low temperature, and the problem that the hot case normal service time caused such as poorly sealed is short.
