Abstract
The invention relates to an Archimedes spiral heater. The Archimedes spiral heater is provided with a cylindrical graphite heating cylinder body (1); and an Archimedes spiral through groove (2) is formed in a cylinder body wall surface of the graphite heating cylinder body (1). The Archimedes spiral heater of the invention has the advantages of structural simplicity, easiness in processing and ingenious design. According to the Archimedes spiral heater of the invention, the design of a slotted hole of a traditional Archimedes spiral heater is modified in that manner that a length of 3 mm is increased, and therefore, efficiency is greatly improved, and temperature can be increased to 1800 DEG C, and time is reduced from 2.5 hours to 1.5 hours.
Description
Technical field
The present invention relates to a kind of graphite heating device, particularly a kind of Archimedian screw heater.
Background technology
Graphite heater is the heater of single crystal growing furnace, and graphite heater adopts isostatic pressing formed graphite electric heating element, has high temperature resistant, easily processing, cost ratio tungsten, molybdenum, the advantage that tantalum is cheap.Though the resistivity of graphite heater is higher than simple metal, for the consideration of intensity aspect, sectional area can not be too little, and therefore the resistance of whole graphite heater is very little, so adopt the mode of heating of low-voltage, large electric current.The performance difference of graphite is very large, and total resistance value is very little, therefore often graphite heater is reprocessed, to reach resistance requirement.Conventionally graphite heater is cylindrical cavity, also has the heater that has Archimedian screw, but the Archimedian screw that its Archimedian screw is standard, the efficiency of heating surface is lower, and the heating time that is heated to uniform temperature is long.
Summary of the invention
The object of the invention is to solve above-mentioned deficiency, provide a kind of efficiency of heating surface high, the Archimedian screw heater that the heating-up time is short.
The technical scheme that realizes the object of the invention is: a kind of Archimedian screw heater, there is cylindrical graphite heating cylindrical shell, and on the cylindrical shell wall of described graphite heating cylindrical shell, have Archimedian screw groove.
Above-mentioned Archimedian screw heater, described Archimedian screw groove is 4 grooves, the spiral that makes progress from the bottom of graphite heating cylindrical shell is offered.
Above-mentioned Archimedian screw heater, the width of described Archimedian screw groove is 4mm.
Above-mentioned Archimedian screw heater, the length of described Archimedian screw groove is the spiral of Archimedes 3mm exceeding according to graphite heating cylindrical shell gained.
Above-mentioned Archimedian screw heater, the terminal of Archimedian screw groove exceeds the length of corresponding points position 3mm in the graphite heating cylindrical shell cross-sectional circumferential at Archimedian screw groove starting point place.
The present invention has positive effect: (1) is simple in structure, easily processing; (2) design ingeniously, break through the fluting design of traditional Archimedian screw heater, increase by the length of 3 mm, efficiency is increased substantially, be increased to 1800 ℃, from 2.5 hours, shorten to 1.5 hours.
Accompanying drawing explanation
For content of the present invention is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein below
Fig. 1 is structural representation of the present invention.
1 graphite heating cylindrical shell wherein, 2 Archimedian screw grooves.
Embodiment
See Fig. 1, the present invention has cylindrical graphite heating cylindrical shell 1, for cylinder hollow structure, on the cylindrical shell wall of graphite heating cylindrical shell 1, have Archimedian screw groove 2,4 grooves start to rotate up fluting from the bottom of graphite heating cylindrical shell 1, the width of groove is 4mm, and length is the length that exceeds corresponding points position 3mm in the graphite heating cylindrical shell cross-sectional circumferential at starting point place.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
