Abstract
The utility model discloses a heating rod of a water heater, comprising a metal tube and a heating wire, wherein the heating wire is arranged in the metal tube and is led out of the metal tube through a connector lug so as to be connected with an external power supply; a compact insulation and heat conduction material is filled between the heating wire in the metal tube and the inner wall of the metal tube and adopts magnesium oxide powder added with silicone oil; and the weight percentage of the added silicone oil is 0.06-0.08 percent. Compared with the prior art, the heating rod is good in corrosion resistance, and can prevent leakage even when being perforated, so that the service life and the safety of the heating rod can be effectively improved and the heating rod is particularly suitable for being used in acidic water quality environment.
Description
Technical field
The utility model relates to a kind of heater, relates in particular to a kind of water heater heating rod.
Background technology
The heating rod of water heater is installed in the heating cup, and it is converted into heat energy with electric energy, for the water in the heating cup heats.One comprises that the outer sleeve that become by stainless steel, dilval, copper and the heating wire in the sleeve pipe form the structure of heating rod.Under the relatively poor situation of water-quality ratio, particularly in part acid water matter area, the heating rod long period of soaking is in acid water, and the outer sleeve of heating rod ratio is easier to be corroded; Along with increasing the weight of of corrosion, finally can cause the perforation of sleeve pipe, the outer water of sleeve pipe will enter inside pipe casing like this, and the Direct Contact Heating silk causes heater strip to fuse because of short circuit, even causes electric leakage, and the user is caused personal injury.
Summary of the invention
The purpose of this utility model provides a kind of safe to use, is applicable to the water heater heating rod that acid water quality is heated.
For achieving the above object, heating rod of the present utility model comprises metal tube and heating wire, and heating wire is arranged in the metal tube, heating wire is drawn metal tube by connector lug, and be connected with external power source, wherein, be filled with closely knit insulating heat-conduction material between heating wire in the metal tube and the inner wall of metal tube.Described insulating heat-conduction material is the magnesia powder that has added silicone oil, and the percentage by weight that wherein adds silicone oil is 0.06%-0.08%.Owing to filled up closely knit insulating heat-conduction material around the heating wire in metal tube, reduced the air content in the metal tube, the oxide etch process of having slowed down inner wall of metal tube effectively.Simultaneously, added the magnesia powder of silicone oil heating wire and metal tube are isolated, even metal tube is bored a hole, heating wire can directly not contact with water yet, has avoided the generation of heating wire fusing fault and electric leakage accident.
The metal tube of the utility model heating rod is oxygen-free copper pipe or titanium pipe.Oxygen-free copper pipe or the titanium pipe has good corrosion resistance can prevent the generation of boring a hole effectively.
Compared with prior art, heating rod of the present utility model has good corrosion resistance, even in the heating rod perforation, also can prevent the electric leakage accident, thereby improve the useful life and the fail safe of water heater heating rod effectively, be particularly suitable in the environment of acid water quality, using.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: Fig. 1 is the overall structure schematic diagram of the utility model heating rod; Fig. 2 is the structural representation of the utility model heating rod; Fig. 3 is the schematic cross-section of the utility model heating rod.
Embodiment
As shown in Figures 1 to 3, heating rod of the present utility model comprises metal tube 1 and heating wire 2, heating wire 2 is arranged in the metal tube 1, heating wire 2 is drawn metal tube 1 by connector lug 3, and be connected with external power source, wherein, be filled with closely knit insulating heat-conduction material 4 between heating wire 2 in the metal tube 1 and metal tube 1 inwall.Described insulating heat-conduction material 4 is for having added the magnesia powder of silicone oil, and the percentage by weight that wherein adds silicone oil is 0.06%-0.08%.Described metal tube 1 is oxygen-free copper pipe or titanium pipe.
Described heating wire 2 can be that the material that is fit in the prior art is made, as nichrome wire, Contra wire, Fe-Cr-Al wire etc.
Described insulating heat-conduction material 4 can also be various insulation filling materials in the prior art, as mica, asbestos, marble, pottery, glass etc., and the mixture of insulating oil such as they and detergent alkylate, polyisobutene, isopropyl biphenyl.
Described metal tube 1 can be difformities such as U-shaped, thread-shaped, W shape, M shape, back-shaped, straight shape, to satisfy different user demands.
Claims (2)
