Also, the metal pipe comprises an aluminum pipe disposed at the external layer and a stainless steel pipe disposed at the internal layer, and the two layers of pipes are in a jointless integral formation. The heating pipe is advantageous in that, assembly is convenient, and insulation and waterproof performances are in accordance with a safety standard.
Description
Technical field
The utility model relates to a kind of heater, a kind of heating-pipe structure of heater espespecially, and this heating tube can be applied to SPA product, swimming pool heating, electric heater, water dispenser, aquaculture, cooking apparatus, heating machinery auxiliary equipment etc.
Background technology
In prior art, generally as shown in Figure 1, it is PTC thermistor 92 of sandwiched before two rectangular tubes 91 for the heater of heater, can produce heat, thereby can the water in two rectangular tubes 91 of flowing through be heated after these PTC thermistor 92 energisings.Yet this processing unit (plant) PTC thermistor 92 when assembling is very easily broken.This be because, in order to increase heat-conductive characteristic, need to make PTC thermistor 92 fully contact with two rectangular tubes 91, therefore generally need to this PTC thermistor 92 be assembled between two rectangular tubes 91 in the mode of mechanical compaction, and being ceramic materials, makes by PTC thermistor 92, frangible, very easily broken in mechanical compaction process like this, be difficult for assembling, will increase cost again.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of easy to assembly, insulate and the heating-pipe structure of the heater of waterproof.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A heating-pipe structure for heater, comprises metal tube, in the outer felt of this metal tube, is wound with constantan wire; This outer surface of metal pipe is coated with a layer insulating, and the outer surface of this constantan wire is coated with one deck dielectric film; Meanwhile, described metal tube is comprised of the two-layer pipe of stainless steel tube that is arranged on outer field aluminum pipe and is arranged on internal layer, and two-layer pipe is jointless one-body molded mode and makes.
The dielectric film of described constantan wire outer face surface is made with silica gel or Teflon (Teflon) material.
The insulating barrier of described outer surface of metal pipe is polyimide insulative layer.
Adopt after such scheme, the utility model utilizes the high resistance of constantan wire, makes constantan wire heating itself after energising, then passes through the conduction of metal tube, and the water in the metal tube of flowing through is heated.This heating-pipe structure tool has the following advantages:
1. without PTC thermistor, assembling is easy, and constantan wire quality is softer, and it is convenient to be wound around, and makes simple.
2. adopt metal tube to be directly wound around constantan wire, closely, heat-conductive characteristic is good in contact.
3. on constantan wire surface, cover dielectric film, can, at metal tube outer cladding insulating barrier, can reach double insulated object simultaneously.
4. the two-layer integrated metal tube that is can be set, to reach the object of two-stage waterproof.And double layer of metal pipe, internal layer can adopt stainless steel tube, and it is strong that stainless steel has corrosion resistance, and therefore the feature of acid-fast alkali-proof is arranged on the internal layer directly contacting with current; And skin can adopt aluminum pipe, the conductive coefficient of aluminium is high, can increase hot conductive performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing heater heater;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 is cutaway view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
What the utility model disclosed is a kind of heating-pipe structure of heater, as shown in Figures 2 to 4, is preferred embodiment of the present utility model.Described heating tube comprises metal tube 1, in the outer felt of this metal tube 1, is wound with constantan wire 2, is coated with one deck makes dielectric film 21 with silica gel or Teflon (Teflon) material at the outer surface of this constantan wire 2.
Operation principle of the present utility model is: owing to containing the metallic elements such as copper, nickel, manganese in constantan wire, therefore it has larger resistance value, when passing into electric current in constantan wire 2, constantan wire 2 itself will produce a large amount of heat, this heat energy can heat the water in the metal tube 1 of flowing through after conducting by metal tube 1.
Because constantan wire 2 is interior, need to pass into electric current, in order to use safety, need to insulate and waterproofing protection.Therefore the utility model carries out overlay film at constantan wire 2 outer surfaces, coated one deck silicone insulation film or Teflon (Teflon) dielectric film 21, and one side can play the object of insulation, can prevent on the one hand constantan wire oxidation.Metal tube 1 itself can play the object of waterproof.
But, for some country, only have one deck insulation and one deck waterproof not to meet safety and require, and need double insulation and two-stage waterproof.Therefore the utility model is further coated with a layer insulating 3 in the outside of described metal tube 1, this insulating barrier 3 can be polyimide insulative layer, thereby reach double insulated object, and the resistance to elevated temperatures of polyimides can also prevent from affecting insulation property because of the high temperature of metal tube.Meanwhile, described metal tube 1 is comprised of the two-layer pipe of stainless steel tube 12 that is arranged on outer field aluminum pipe 11 and is arranged on internal layer, and two-layer pipe is jointless one-body molded mode and makes, thereby can reach the object of two-stage waterproof.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, thus variation or the modification in every case according to claim of the present utility model and specification, done, within all should belonging to the scope that the utility model patent contains.
