The present invention in use,
For existing composite copper aluminium radiator, general heat source is boiler, pipeline, wall-hung boiler, for central heating
Mode, whether radiator or floor heating typically provide heat source using coal is burnt, and burn coal and waste mass energy, Er Qiemei
Charcoal is non-renewable energy resources, it is even more important that burning coal will cause environmental pollution and cause greenhouse effects.
Traditional collective's heating type not can control the heating time, and the heating time will be unified point according to the regulation of government department
Match, cannot independently select, no matter and family whether someone, whole day heating, cause the waste of the serious energy and financial resources, tie up
Inconvenience is repaired, evaporating, emitting, dripping or leaking of liquid or gas phenomenon easily occurs, when replacing house, can not remove, be substantially disposable, cause resource
Waste.
The present invention can be in autonomous control, can also be certainly even if not reaching collective's heating date when weather turns cold
It is leading to drive capable heating into, when going out, it can close, economize on resources at any time, there is no water inside structure of the invention, so being not in
Evaporating, emitting, dripping or leaking of liquid or gas phenomenon, it is easy to maintenance simple, when replacing house, radiator can be taken away at any time together, reuse, energy consumption
Using ceramic PTC ceramic heating Manifold technology, power consumption is also very low.
For air-conditioning and electric radiator, terminal heating water temperature is not reached requirement, needed for causing room temperature to be not achieved
Temperature, and the heating of electric radiator is not able to satisfy heating area, and in the prior art the material problem of electric radiator to
Keep the energy consumption of electric heater very high.
The present invention changes heat source medium, using ceramics as medium, using terminal heating sheet, reaches independent heating behavior energy saving
Purpose, do not limited by the heating time, instant-heating.
Quick detachable, energy conservation and environmental protection of the invention changes central heating mode, by new using the high cleaning energy as heat source
Heat source achievees the purpose that heating.
PTC ceramics heat-generating pipe is plate face fever and the not charged and flames of anger, shape are square, safety after a kind of energization
Reliable Electrothermal plate.Mainly by heat transfer, therefore the thermal efficiency is high when heating plate is due to using.PTC ceramics heat-generating pipe is existing
Mature technology, but the PTC ceramics heat-generating pipe of all productions in the market is made a general survey of, PTC ceramics heat-generating pipe is all rectangular patch,
Not cylindrical, because PTC ceramics heat-generating pipe needs are combined closely, and circular tube shaped can not combine closely, so existing skill
In art, round tube PTC ceramics heat-generating pipe is not all done, and do not grasp the technology, is all the rectangular sheet directly produced
PTC ceramics heat-generating pipe.
PTC type ceramic heater is formed with ripple aluminum strip through high temperature gluing using PTC ceramics heat generating component.The type PTC
Heater has the advantages that thermal resistance is small, heat exchange efficiency is high, is the electric heater of a kind of automatic constant-temperature, power saving.Its one is big prominent special
Point is in security performance, and surface " rubescent " phenomenon such as electric heating tubing heater will not be generated under any applicable cases, from
And cause to scald, the security risks such as fire.
Most significant feature is:
1.PTC type ceramic heater cost-saving, long-life.
Not needing the temperature sensors such as special temperature controller and thermal resistance thermocouple progress temperature feedback can be to heater
Fever control is carried out, it is the material property for leaning on itself that its temperature, which is adjusted, so that product be made to have much larger than other heaters
Service life.
2.PTC type ceramic heater safety, it is environmentally protective.
The design heating temperature of heater body is in 200 degrees Celsius of multiscales below, and ontology is not sent out in any case
Red and have protecting insulating layer, any application does not need the heat-barrier materials such as asbestos and carries out cooling processing, can it is safe to use not
There are problems that scalding human body and causing fire.
3.PTC type ceramic heater saves electric energy.Compare electrothermal tube and Resistant heating product, this product is to lean on material certainly
The characteristic of body adjusts the thermal power output of itself according to the change of environment temperature, so it can be by the power consumption of heater
Optimal control is in minimum, while the material of high heating efficiency also greatly improves the utilization efficiency of electric energy.
The shape of this clearly demarcated tubular ceramic heat-generating pipe is not limited to cylinder, or other shapes such as rectangular, triangle
Shape, but the method and process of production mold are consistent.
When carrying out tube expansion technique, mold is inserted into wire-passing tube, is uniformly swollen with mechanical expansion head, guarantees the mistake of mold
It is full of expanded joint, and mold is uniformly contacted with wire-passing tube, ensure that combining closely for wire-passing tube and mold, reduce thermal resistance, guarantee heat transfer.
Composite copper aluminium radiator welding manner is welded using soldering tech, selects corrosion-resistant, good fluidity soldering
Material increases molten bath volume when machine drill hole is anti-by the way that Full-automatic drilling is anti-as solder, header tube in the welding process,
Solder and parent is set to have bigger contact area, to ensure that welding quality.
An open question is to change heat always in Important Problems to be solved by this invention, and field personnel of the same trade
The mode in source, by the way of electricity heating.
The mode of electricity heating has air-conditioning and electric radiator, and more than the heating system of both gradually analyzes.
Technical problem solved by the invention is cylindrical PTC ceramics heat-generating pipe, and traditional PTC ceramics heat-generating pipe is all square
Shape sheet, and also do not produce, the prior art can not also produce cylindrical PTC ceramics heat-generating pipe.
Copper aluminium ceramic thermostatic radiator is that low energy consumption, energy-saving and environment-friendly product for my one kind of company's independent research, is had anti-
The big feature of burn into pressure-bearing, effective solution steel radiator, the perishable defect of Aluminium Radiator, while with aluminium
As heat dissipation element, easily molded, light, perfect heat-dissipating all advantages of aluminum have been played.
Country, which calls, now will protect environment, save the energy, adopt a series of measures, and by taking Beijing as an example, country releases coal
Change electric policy, heating mode development in Pekinese's is made from the former central heating for burning coal, to become household electrical boiler etc., but just
For current Beijing sale electric boiler, electric boiler price is prohibitively expensive, and power-consuming amount is too big, and many citizen are subject to not
It rises.
The public policy for being intended to reduce city winter pollution that caused by coal burning as one, improving Beijing air quality, Beijing is certainly
From 2001 implement " coal changes electricity " engineering, exceeded 14 years up to the present, but in Beijing residents the phenomenon that " double track " and " electricity changes coal " still
Generally existing, reason or electric boiler is expensive eventually, and power consumption is big.
The present invention connects into one group of radiator, the several factually interphases of the group of specific radiator with more vertical wire-passing tube columns
Depending on long-pending needs, it is directly connected between multiple groups radiator by lower end.
There are triangle sockets at inferior horn of the invention, and are configured with power supply line, and power supply line is equipped with temperature controller and multi-functional
Switch button.
Structure of the invention is ingenious, is not limited by the heating time, can heat at any time, the free control of heating duration, saves
Mass energy, using the form of terminal heating sheet, achievees the purpose that independent heating, behavior are saved using ceramics as medium.
