Technical field
The utility model is related to novel heater technical field, specially a kind of full closed pipe type PTC heater.
Background technology
PTC heaters are a kind of Novel heating bodies for the constant temperature that insulate, and two metal sheets are stained with the both sides of PTC heater elements,
And draw two wires as powered electrode, without separately adding temperature regulating device, with sustainable heating, safe and reliable, power stability makes
With voltage it is wide the features such as.
Existing PTC heater part mainly has two kinds of forms, and a kind of is the powered type in surface, and one kind is the not charged type in surface
, the PTC heater part of the powered type in surface is that heat sink strip is directly bonded on PTC heater elements with heat-conducting glue, then from radiating
The anode and cathode terminals of electrode are directly led out on bar.The advantage of this powered type PTC heater part in surface is：It is simple in construction tight
Gather, small volume, heat transfer is direct, and thermal conversion efficiency is higher, and the heating power of unit volume device is larger.But its major defect is
Whole device surface is powered, and in use in the presence of certain potential safety hazard, and electrode is directly exposed in air, it is possible to because
The environmental factors such as moist or dust cause to strike sparks and fail, therefore this device has very big limitation using upper.
Existing heating element overheat can cause itself to damage and imprudence can scald human body, or even causes circuit short
Road phenomenon, so that electric leakage is produced, the problems such as threatening personal safety or trigger fire.In addition, after these heating element heat production, from
Body is difficult cooling, and reduced lifetime, PTC heater many at present is pursued heating efficiency height, heat transfer speed and soon and often ignored
Energy-conservation this point.
Utility model content
The purpose of this utility model is to provide a kind of reasonable in design, and with the good not charged effect in surface, uses
It is safety, compact conformation, easy to process, big and with good heat sinking function with caloric value, power stability, it is noiseless, make
With long lifespan, reliability is high, have a safety feature the characteristics of, it is now widely available in air-conditioning, disinfection cabinet, dryer, household electrical appliances one
Full closed pipe type PTC heater is planted, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of full closed pipe type PTC heating elements, bag
PTC heater body, PTC heater elements are included, the PTC heater body is provided with PTC heater elements, the PTC heatings member
