Description
Technical field
This utility model belongs to electric-heating technology field, is specifically related to a kind of electric heater.
Background technology
Along with industrial expansion, the life of people also develops in the direction tending to facilitation, electric heater is as one heating tool easily, important role is play in Modern Live, owing to water quality all over the world differs greatly, in heating process, heating pipe of water heater is also had damage in various degree, particularly corrosion and the problem of surface scale.
Owing to producing electromotive force when electric heating tube works, defining potential difference (i.e. galvano-cautery), the most potential differences of water mineral are the biggest, corrode the most serious.The most directly using the situation of subsoil water, the heating metal pipe great majority in currently used electric heater are nickel-base alloy (800) stainless steel tube, after a procedure must be bad after 1-3 month, and the life-span is short, need to often change, and work and life to us make troubles.In order to solve to add heat pipe etching problem in electric heater, some enterprise is considered as noble metal, such as gold-plated at outer surface of metal pipe.This way also can play antisepsis, but cost is high, and preparation procedure is complicated, is unfavorable for environmental protection, and also easily causes damage to adding heat pipe in gold plating process；In addition, the most existing heating pipe of water heater surface is easily formed incrustation scale, prolongation in time, and incrustation scale thickens, and affects the carrying out of heat exchange, reduces heat transfer efficiency, and impact is normal to be used.
Titanium is a kind of rare metal, particularly has good resistance to corrosion (including resisting sea water, chloroazotic acid and the corrosion of chlorine) and good antiscale property characteristic.Due to the chemical property that it is stable, good high temperature resistant, low temperature；Anti-strong acid, highly basic and high intensity, low-density, be " space metal " by good reputation, be commonly used as various reaction vessel, be usually used in aerospace industry and marine industries.Owing to the heat pipe that adds in electric heater is to be directly welded on flange by soldering or argon arc welding, flange is connected in the water storage tank inner container of water heater, and be difficult to weld between Titanium with other metals, therefore it is not easy to be fixed in electric heater Titanium pipe.
Patent CN202565485 discloses a kind of electric heater, and open further include that titanium adds heat pipe and flange, described titanium add between heat pipe and flange by riveting in the way of be sealedly and fixedly connected, this electric heater has the advantages such as anti-corrosion capability is strong, but it uses specific flange-interface that titanium is added heat pipe and seals, on the one hand both rely on intermetallic mutual extruding to reach to be tightly connected, and sealing effectiveness can reduce with the prolongation of the time of use；On the other hand, this structure seals except using specific flange-interface, also needing in use connect external flanges, therefore the structure of external flanges need to depend on the flange-interface of this structure, and the course of processing of finished product is complicated, marketing is the highest to cause this structure to be made.
Summary of the invention
Goal of the invention: this utility model purpose is for the deficiencies in the prior art, it is provided that a kind of corrosion resistance and good, good antiscale property, water-impervious, life-span length, electric heater applied widely.
Technical scheme: a kind of electric heater described in the utility model, including adding heat pipe and base, described in add heat pipe be steel titanium composite heating pipe, be placed through in described base after the port riveting fixed cover of described steel titanium composite heating pipe.
Further, described steel titanium composite heating pipe includes that rustless steel tube layer and titanium tube layer, described titanium tube layer are coated on the surface of described rustless steel tube layer.
Further, for improving the fitness between fixed cover and base, reduce and connect gap, described fixed cover includes wide mouth section and slot section, connected by taper seat between described wide mouth section and slot section, described wide mouth section is coated on described steel titanium composite heating pipe, arranges insulating blanket, with the fixed seal connection that presses in wide mouth section and between steel composite ti pipe；Described slot section presses with the port of described steel titanium composite heating pipe in the mating holes inserting described base after being connected.
Further, described insulating blanket is electro-insulating rubber bed course.
Further, described fixed cover is stainless steel.
Further, the joining place soldering of described fixed cover and described base connects or nickel is welded to connect.
Further, described base, fixed cover and adding is connected by argon arc welding at the connectivity port of heat pipe.
Beneficial effect: (1) this utility model uses steel titanium composite heating pipe to substitute existing nickel-base alloy stainless steel tube, utilize the high chemical stability of titanium, highly corrosion resistant and good anti-surface scale performance, not only solve because adding the problem that heat pipe is corroded and service life of causing is short, also solve because adding the problem that tube surface fouling reduces heat exchanger effectiveness；(2) this utility model by riveting fixed cover in the port of steel titanium composite heating pipe, and arranges felt pad between heat pipe and fixed cover adding, and improves the sealing of heating pipe port；Heat pipe will be added by fixed cover to be fixed on base, solve the problem that heating tube and tube seat can not directly weld, and the joining place of fixed cover Yu base is designed as taper, and uses nickel weldering or soldering caulking joint, the most effectively prevent water from penetrating into mating holes while the fitness both improving；(3) this apparatus structure is easy, is not required to extra sealing flange, easily processes, it is adaptable to the electric heater external flange of various structures, and marketing is high, and application prospect is preferable.
