Abstract
The utility model relates to equipment for heat or hot water supply, heating and freeze protection for other pipelines and assisting in heating. The equipment comprises a liquid duct, a heating wire mounted on the outer surface of the liquid duct and an outer duct covering the heating wire. The equipment is characterized in that a helical groove is arranged on the outer surface of the liquid duct, and the heating wire is wound in the helical groove. The equipment is used for heating step by step on a water and power separation condition, and is simple in structure, convenient to mount and low in noise during heating. The heat conversion rate is increased by 35%, and the service life of the equipment is at least four times of that the other products. As the power of the equipment can be set optionally, the equipment has a wide service range.
Description
Technical field
The utility model relates to the heating of a kind of heating industry and various pipelines, antifreeze, and the device that solar energy, water resource heat pump, air can heat supply assistant heating heating goods, especially a kind of duct type electric heater.
Background technology
At present in whole heating industry along with the scarcity of the constantly soaring and non-renewable resources of coal price, electric heating, electrical heating become the people's attention point.The heating mode commonly used that is used for electric heating now has three kinds, electrothermal tube (heating wire) heating, electromagnetism heating, PTC heating.But all there is weak point in these three kinds of heating modes commonly used, specifically are: (1) electrothermal tube mode of heating is the most original mode of heating; Safety coefficient is low, efficiency ratio, electrothermal tube in heating process its surperficial incrustation scale along with the prolongation of service time; Incrustation scale is constantly thickeied, and internal heat can't discharge, the final damage; Life-span is short, noise is big when heating, fault rate is high, and installs loaded down with trivial details; (2) though the electromagnetism heating mode has firing rate improves relatively, the advantage of safety coefficient high (electricity separation) is owing to production technology, components and parts cost are higher; Structure division is complicated; Fault rate is high, and the life-span is short, and noise is arranged in the heating process; The radiation that generates electromagnetic waves is harmful, particularly to child, children, and pregnant woman's harm maximum; (3) because PTC, the PTC heating mode has that noise is big, and heating moment surge current is maximum, and system is easy to generate various faults and harm, and shortcoming such as Energy Efficiency Ratio is lower.
The utility model content
The technical problem that the utility model will solve provides the high duct type electric heater of a kind of thermal conversion rate.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of duct type electric heater comprises catheter, is wrapped in the heating line on the catheter outer surface and wraps in the outside outer tube of heating line; Its key is: the outer surface of said catheter is provided with helix groove, and said heating line is wrapped in the helix groove.
The two ends of above-mentioned catheter are provided with the pipeline connector of band screw thread, and the inboard of pipeline connector is provided with type of tamper evidence.
Scribble insulated paint on the surface of above-mentioned helix groove
Be enclosed with insulated hull on the outer surface of above-mentioned heating line.
Be provided with heat-insulation layer between above-mentioned heating line and the outer tube.
Adopt the beneficial effect that technique scheme produced to be: the utility model is a kind of be used for heating or hot water supply, and for other pipelines heat, antifreeze and as the equipment of assistant heating.The utility model adopts progressive heating mode, electricity separation, the inner water flowing of catheter or other liquid; The catheter outer surface is provided with the helical form wire casing, and the heating line twines by certain requirement according to wire casing, and the heating line is more pressed close to catheter; Effectively strengthened the contact area of calandria and heated body; Therefore, than heating mode commonly used, thermal conversion efficiency can effectively improve 35%; Pipeline connector and type of tamper evidence are convenient to the pipeline installation; The insulated paint that scribbles on the helix groove surface can prevent unexpected electric leakage accident; Be enclosed with insulated hull on the outer surface of heating line, intensity is high, high temperature resistant, wear-resisting anticorrosive; Heat-insulation layer has prevented the heat reduction noise of becoming estranged.The utility model is simple in structure, easy for installation, uses flexibly, and fault rate is low, and cost and operating cost are lower; The heating process noise is low, and thermal conversion rate improves 35%, and prolong 3 times or more than other products service life; Power can be set arbitrarily, and the scope of application is wide, except that independent use also can with wind energy, solar energy, water can, equipment organic assembling such as air ability and other hot water, heating.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1, catheter, 2, the heating line, 3, heat-insulation layer, 4, insulated hull, 5, outer tube, 6, helix groove, 7, insulated paint, 8, the pipeline connector, 9, type of tamper evidence.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Be illustrated in figure 1 as the structural representation of the utility model.The utility model comprises catheter 1, and the two ends of catheter 1 are provided with the pipeline connector 8 of band screw thread, and the inboard of pipeline connector 8 is provided with type of tamper evidence 9, so that the installation of pipeline; The outer surface of catheter 1 is provided with helix groove 6; Scribble resistant to elevated temperatures insulated paint 7 on the surface of helix groove 6; Heating line 2 closely is wrapped on the outer surface of catheter 1 by the trend of helix groove 6, and is enclosed with resistant to elevated temperatures insulated hull 4 on the outer surface of heating line 2; Like this, heating line 2 is more pressed close to catheter 1, can effectively strengthen the contact area of calandria and heated body, calculates the length of catheter 1 and the length of heating line 2 according to the different capacity of confirming, carries out the assembling with other parts after heating line 2 twines and finishes; The outside of heating line 2 is provided with heat-insulation layer 3 and outer tube 5 successively, and heat-insulation layer 3 and outer tube 5 can effectively prevent the heat reduction noise of becoming estranged.
