Abstract
The utility model relates to an inner tube type PTC heater. The utility model is characterized in that an aluminium pipe is provided with PTC heating sheets inside, and the PTC heating sheets are arrayed with space; the two sides of the PTC heating sheets are connected with electrodes; the circumference of the PTC heating sheets and the electrodes are coated with insulating materials to isolate the aluminium pipe; the two heads of the aluminium pipe are sealed by seal heads; the two sides of the aluminium are respectively connected with a heat dispersion set. The utility model has the advantages of better heat dispersion effect, aging resistance, safe utilization, and easy fabrication. The surface of the utility model is without electricity.
Description
The utility model relates to heating element, especially adopts the heating element of PTC pottery as heater.
At present, the heating element made from the PTC ceramic heating element has a lot, is applied in all kinds of heaters, still, when being applied among the wet environment, tend to make heater to produce electrification phenomenon, produce unsafe factor, its heater element is placed in the middle of the fin in some heating elements in addition, like this when making small-sized heating element, bring difficulty to manufacturing, and the area of heat radiation is little, efficient is lower.
It is not charged that the purpose of this utility model provides a kind of surface, the PTC heater that area of dissipation is big.
The technical solution of the utility model is characterized in that being equipped with in the aluminum pipe spaced PTC heating sheet (1), at PTC heating sheet (1) both sides connection electrode (2-1), (2-2), with insulating material (3) wrap in PTC heating sheet (1), electrode (2-1), (2-2) around, and separate with aluminum pipe (4), there is end socket (6) at the two ends of aluminum pipe (4) and with the insulating cement sealing, connects one group of fin (7), (8) in the both sides of aluminum pipe (4).
The utility model encases owing to PTC heating plate electrode all is insulated material, isolated with the inwall of aluminum pipe, seal with end socket and insulating cement at two, so, its insulation property are good, make aluminum pipe not produce electrification phenomenon, guarantee to be applied in not produce electrification phenomenon in the heater, in addition because of heater, adopt the groups of fins of both sides, strengthen the area of heat radiation, increased the speed of heat radiation, improved the efficient of heat radiation, owing to adopt both sides to connect fin, so groups of fins can be used as parts and produces in batches, improved the product quality and the production cost of fin, and the method that can adopt welding that is connected of groups of fins and aluminum pipe, also can adopt the bonding method of silica gel, easy to connect, easily manufactured.Because heater element all is sealed in the aluminum pipe, the contact of discord air is difficult for wearing out long service life.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of interior tubular type PTC heater.
Embodiment:
Referring to Fig. 1 as can be known, spaced PTC heating sheet (1) is housed in aluminum pipe (4), the material of PTC heating sheet (1) is a pottery, at each connection electrode of both sides (2-1), (2-2) of PTC heating sheet.The material of electrode is a copper sheet, the end welding binding post (5-1) of electrode (2-1), the end welding binding post (5-2) of electrode (2-2).Used insulating material adopts high-temperature insulation paper, the also film that can make with other resistant to elevated temperatures polytetrafluoroethylmaterial material, with insulating cement end socket (6) is gluedd joint with two of aluminum pipe (4) then and shut, two binding posts (5-1), (5-2) pass end socket at two of aluminum pipe (4), in the both sides of aluminum pipe (4) the bonding connection groups of fins of high-temperature plastic (7), groups of fins (8).Tubular type PTC heater in becoming.
The utlity model has on the heating element surface not charged, good heat dissipation effect, the thermal efficiency Height, ageing-resistant, use the characteristics such as safety.
Claims (1)
1, a kind of interior tubular type PTC heater, it is characterized in that in aluminum pipe (4), being equipped with spaced PTC heating sheet (1), at PTC heating sheet (1) both sides connection electrode (2-1), (2-2), wrap in around PTC heating sheet (1) and electrode (2-1), (2-2) isolated with insulating material (3) with aluminum pipe (4), there is end socket (6) at the two ends of aluminum pipe (4) and with the insulating cement sealing, respectively connects a groups of fins (7), (8) in the both sides of aluminum pipe (4).
