Abstract
The utility model relates to a soft armoured sealed heater, which comprises metal extraction electrodes and heating wires. The utility model is characterized in that the outer sides of the metal extraction electrodes and the heating wires are welded with insulated sealing ends and outer sleeve tubes made of ultrathin metals, and heat transferring insulating materials are arranged between the outer sleeve tubes and the heating wires. Because the utility model adopts ultrathin metals to make outer sleeve tubes, the shape of the outer sleeve tubes can be bent at will according to the requirements on the spot, and the minimum bending radius can reach 10 mm. Simultaneously, the utility model adopts a welded seal form, therefore, various vacuum devices can be used, the insulation problem does not need considering, and the operation is convenient.
Description
The utility model is a kind of heating element, particularly a kind of software armouring closed feed water heater.
The heater of people's use now generally all is a fixed in shape, and therefore the heater of this fixed in shape can not make the people feel very inconvenient with using on-the-spot difference change shape sometimes.In addition, existing armoured thermocouple is a rubber sealing, so it can not be used in the vacuum equipment.
The purpose of this utility model provides a kind of novel heater, and it can overcome existing shortcoming in the prior art, can change shape, for use provides bigger convenience.
The purpose of this utility model is achieved in that it comprises metal extraction electrode and heater strip, it is characterized in that the outer tube that the outside of metal electrode and heater strip is welded with the insulated enclosure termination and makes with super thin metal, the heat transfer insulating material is housed between outer tube and heater strip.
Insulating end in the heater of the present utility model adopts pottery to make, and adopt soldering or inferior arc-welding welding between the metal extraction electrode, it is that 1mm following stainless steel tube or Titanium pipe are made that outer tube adopts thickness, also can adopt titanium alloy or zirconium alloy pipe to make, heater strip can be one or more.
The utility model is owing to adopted super thin metal to make outer tube, so can looking, its shape uses on-the-spot requirement and arbitrarily bending, minimum bending radius can reach 10mm, simultaneously owing to adopted the seal form of welded type, so can be used in various vacuum equipments, and it is needn't consider Insulation Problems, so very easy to use.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the structure cutaway view of a kind of specific embodiment of the present utility model.
6 is metal extraction electrodes among the figure, is welded with heater strip 3 at its afterbody, and the outside of metal extraction electrode is welded with ceramic insulation termination 5, and is welded with outer tube 2 by excessive circle 4, is filled with the heat transfer insulating material 1 that magnesia powder is made between heater strip and outer tube.
