Abstract
Disclosed is a cast copper electric heater with high efficiency, comprising a cast copper heating pipe, wherein the cast copper heating pipe comprises a bare copper pipe; the pipe wall of the bare copper pipe is internally provided with an electrothermal pipe; the power supply input terminal of the electrothermal pipe is respectively connected with binding posts arranged upon the surface of the cast copper heating pipe; the heating wire inside the electrothermal pipe adopts a nichrome wire which is helically arranged in the axial direction inside the electrothermal pipe; the gap inside the electrothermal pipe is filled with oxidation magnesia; and two ends of the electrothermal pipe opening are sealed with silica gel. The cast copper electric heater of the utility model employs an electrothermal pipe as the heat-generating body and utilizes high-quality copper material to arrange the electrothermal pipe inside the pipe wall of the bare copper pipe in a centrifugal type casting mode, with the using temperature thereof ranging from 150 to 450 DEG C. The cast copper electric heater can be widely applied to plastic machinery, die head, cable machinery, chemical, rubber, petroleum, and the like, featuring long service lifetime, excellent thermal insulation performance, powerful mechanical property, corrosion resistance, anti-magnetic field, and so on.
Description
Technical field
The utility model relates to a kind of electric heater, relates in particular to a kind of cast copper electric heater of efficient heat transfer, belongs to the production field of electric heater.
Background technology
Electric heater is used to the miscellaneous equipment heating, as is widely used in using very extensive on the equipment such as plastics machinery, die head, cable machinery, chemical industry, rubber, oil.Electric heater is owing to fast, the easy to use first-selection that becomes firing equipment of programming rate.
The conventional electric heating device generally adopts corrosion resistant plate parcel electrothermal tube to be made, because gapped between electrothermal tube and the corrosion resistant plate, and the heat conductivility of stainless steel itself can not reach best, so can cause the heat conductivility deficiency of whole electric heater; In addition, when using, usually can only use the part surface of heater, and the whole surface of heater all is the condition of high temperature,, has increased thermal losses, reduced the heat transfer efficiency of heater so can cause great amount of heat to run off.
Summary of the invention
The purpose of the utility model just is to provide in order to address the above problem a kind of cast copper electric heater of efficient heat transfer, and this electric heater utilizes copper to be heat conductor, and electrothermal tube is placed closely contact in the naked copper pipe, and integral body has promoted heat transfer efficiency.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises the cast copper heating tube, and said cast copper heating tube comprises the naked copper pipe, is provided with electrothermal tube in the tube wall of said naked copper pipe, the power input of said electrothermal tube respectively be arranged at the lip-deep binding post of said cast copper heating tube and be connected.
The utility model is heater with the electrothermal tube, electrothermal tube is arranged in the tube wall of naked copper pipe with centrifugal casting mode with the high-quality copper product, and generally between 150～450 degree Celsius, utilization efficiency of heat energy is very high for its serviceability temperature.
Particularly, the heating wire in the said electrothermal tube is the nichrome wire that is provided with along center axial screw in the pipe, and the space in the said electrothermal tube is filled with magnesium oxide sand, and silica gel sealing is used at said electrothermal tube mouth of pipe two ends.The heat-generating pipe of this structure not only has high electric heating conversion ratio, and its stability is high, the life-span is long.
As preferably, said electrothermal tube is wound in the tube wall of said naked copper pipe.Make the heat generating spot density in the naked copper pipe high, electrothermal calefactive rate is fast.
Further, the outside of said naked copper pipe is coated with heat-insulation layer; Said heat-insulation layer is the rock wool heat-preservation layer.Heat-insulation layer is used for the heat of the utility model is kept not lost as much as possible, can significantly improve the utilance of heat.
The beneficial effect of the utility model is:
The utility model is heater with the electrothermal tube; Electrothermal tube is arranged in the tube wall of naked copper pipe with the high-quality copper product with centrifugal casting mode; Its serviceability temperature is generally between 150～450 degree Celsius; Can be widely used on the equipment such as plastics machinery, die head, cable machinery, chemical industry, rubber, oil, have advantages such as life-span length, good heat insulating, strong, corrosion-resistant, the diamagnetic field of mechanical performance; In addition, through heat-insulation layer is set, the Btu utilization efficient of the utility model is significantly improved.
