Description
Technical field
The utility model relates to ptc heater technical field, specifically a kind of scale-proof boiler PTC heating with internal lining pipe
Device.
Background technique
PTC electric heater is the heating element that a kind of shell is aluminum profile, and when as boiler heater, water is out of heater
Portion's tube body passes through, and since water quality is harder, when heating is easy in aluminium shape surface fouling, after a period of time, PTC electricity
The inner surface of hot device gathers a large amount of scales and causes heating efficiency low, or even booster occurs, and influences service life and safety.
Summary of the invention
To solve the above-mentioned problems, the utility model proposes a kind of scale-proof boiler ptc heater with internal lining pipe.
A kind of scale-proof boiler ptc heater with internal lining pipe, including ptc heater, the ptc heater be built-in with
The copper internal lining pipe of ptc heater inner wall fitting, described two ends of ptc heater are provided with for realizing water is passed in and out
Intake-outlet component.
The cross section of inboard wall of the ptc heater is circle, and the ptc heater inner wall end is equipped with built-in spiral shell
Line.
The copper internal lining pipe is cylindrical shape, and the copper internal lining pipe is anaerobic copper sleeve.
The fixation of the copper internal lining pipe and ptc heater is realized by expander technique.
The intake-outlet component include connected unit identical with the cross-sectional shape of ptc heater, setting connecting
Intake-outlet on platform, the nut being arranged on intake-outlet.
The intake-outlet is step-like distribution, and one end of the intake-outlet is the straight cylinder of smooth outer surface,
The other end of the intake-outlet is the straight cylinder that outer surface has threaded line.
The disposed thread of the outer surface of the intake-outlet one end and ptc heater with threaded line cooperates.
The internal diameter of the copper internal lining pipe is less than or equal to the diameter of intake-outlet.
The beneficial effects of the utility model are: reducing ptc heater using the copper internal lining pipe being arranged in ptc heater
The cross-sectional area of inner surface, increases flow velocity, and the increase of flow velocity and the use of oxygen-free copper material can effectively reduce inner surface
The generation of scale；Copper product corrosion resistance is strong, can extend ptc heater service life, reduces the danger that booster occurs；Utilize expander
Technique guarantees that the outer wall of copper internal lining pipe is bonded with the inner wall of ptc heater and increases heat transfer efficiency.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the schematic perspective view after the removal ptc heater of the utility model；
Fig. 3 is the ptc heater sectional perspective structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
It is further described in face of the utility model.
As shown in Figure 1 to Figure 3, a kind of scale-proof boiler ptc heater with internal lining pipe, including ptc heater 4, it is described
Ptc heater 4 is built-in with the copper internal lining pipe 5 being bonded with 4 inner wall of ptc heater, and described 4 two ends of ptc heater are all provided with
It is equipped with for realizing the intake-outlet component for passing in and out water.
One layer of red copper material is arranged in the inside of ptc heater 4 in the characteristics of being easy to produce scale for ptc heater 4
Copper internal lining pipe 5 is fixed using expander technique, and after copper neck bush 5,4 inner surface water of ptc heater can be effectively reduced
The generation of dirt extends the service life of ptc heater 4, reduces the danger that booster occurs.
The cross section of inboard wall of the ptc heater 4 is circle, and the 4 inner wall end of ptc heater is equipped with built-in spiral shell
Line.
The cylinder of protrusion is provided on two ends of the ptc heater 4.
The copper internal lining pipe 5 is cylindrical shape, and the copper internal lining pipe 5 is anaerobic copper sleeve.
The fixation of copper internal lining pipe 5 Yu the ptc heater 4 is realized by expander technique.
Use copper internal lining pipe 5, one side pure copper material corrosion resistance and good, surface non-oxidation protective layer, it is not easy to occur
The defects of spot corrosion, causes scale to gather；Another aspect pure copper material excellent thermal conductivity reduces the hair of PTC caused by conduction inequality
The problems such as hot 4 power swing of device.
The intake-outlet component includes connected unit 3 identical with the cross-sectional shape of ptc heater 4, setting even
Intake-outlet 1 on consecutive 3, the nut 2 being arranged on intake-outlet 1.
The intake-outlet 1 is step-like distribution, and one end of the intake-outlet 1 is the straight circle of smooth outer surface
Cylinder, the other end of the intake-outlet 1 are the straight cylinder that outer surface has threaded line.
The disposed thread of the outer surface of the intake-outlet 1 one end and ptc heater 4 with threaded line cooperates.
The internal diameter of the copper internal lining pipe 5 is less than or equal to the diameter of intake-outlet 1.
According to the caloric receptivity of formula water:
QIt inhales=PPowerT=Cm Δ t
M=ρ VVolume=ρ * S*VSpeed*t
P=ρ * S*VSpeed
The increase of the copper internal lining pipe 5 reduces the cross-sectional area of 4 inner surface of ptc heater, increases flow velocity, and flows
The increase of speed can effectively reduce scale and be formed；In addition, the processing is simple, and copper product using expander technique fixed copper internal lining pipe 5
The excellent outer surface that can guarantee copper internal lining pipe 5 of processing performance be bonded with the inner surface of ptc heater 4, increase heat transfer efficiency.
