Abstract
The utility model discloses a tube-shaped PTC heater, which belongs to the technical field of electric heaters, in particular to a heating device applied to an air conditioner or an air heater. The heating device comprises a radiator, an insulation layer, a ceramic PTC element, an electrode plate and a tamper, wherein the radiator consists of a flat tube and a radiator fan, and is characterized in that the flat tube and the radiator fan are in an integral structure, and that the radiator fan is a fin; the insulation layer is added on the circumference of the inner wall of the flat tube of the radiator; the external surfaces of the two side walls of the flat tube of the radiator are arranged with inward concave small grooves; the inner cavity walls of the flat tube of the radiator are arranged with convex steps. Compared with the prior art, the utility model has the advantages of simple and compact overall structure; high heating efficiency and fast temperature rise rate; rational structure and eye-pleasing appearance; and long service time. Besides, the utility model gets rid of the necessity of a bolt connection.
Description
Technical field:
The utility model relates to a kind of tubular PTC heater, and it belongs to the electric-heating technology field, particularly a kind of heater members that is mainly used on air-conditioning or the warm-air drier.
Background technology:
In the prior art, adopt electrothermal tube etc. more, also have and adopt the PTC heating as heater.As: the patent No. is 98329249.3 " wall-hanging air conditioner ptc heaters "; And for example: the patent No. is: 99302507.2 " wall-hanging air conditioner heaters ".These heaters make that all owing to structure is numerous and diverse its radiating effect is bad, have also seriously influenced the useful life of product simultaneously, and in addition, overall appearance is bad, is unfavorable for the installation and the use of heater.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and has better heat radiating effect, do not allow flimsy tubular PTC heater.
The purpose of this utility model is achieved in that
A kind of tubular PTC heater, it comprises radiator, insulating barrier, ceramic PTC element, battery lead plate and chock plug, described radiator is made of flat tube and fin, it is characterized in that described flat tube and fin are monolithic construction, and described fin is the fin type fin.
Around the inwall of the flat tube of described radiator, add pad dielectric layer.
The bonding connection between described ceramic PTC element and battery lead plate.
Be that the adhesives that is bonded between described ceramic PTC element and the battery lead plate is an organic silica gel.
Outer surface in the two side of the flat tube of described radiator is provided with the sulculus of indent.
The thickness of described fin type fin is 0.1～0.4mm.
On the internal chamber wall of the flat tube of radiator, be provided with the protrusion step.
The utility model volume is little, in light weight, increases area of dissipation, improves heat dispersion.This reality is compared with prior art novel, has the following advantages: without latch, need not connect; Overall structure is simply compact; Heat efficiency height, programming rate is fast; Rational in infrastructure, good looking appearance, long service life.
Description of drawings:
Accompanying drawing 1 is an overall structure schematic diagram of the present utility model
Accompanying drawing 2 is a cross sectional view of the present utility model
Embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2 below, the utility model be further detailed:
The utility model is by radiator, insulating material 2,3, and ceramic PTC element 4, battery lead plate 7 and chock plug 6 are formed.Pottery PTC element 4, battery lead plate 7, the assembly structure of forming with chock plug 6 and form are identical with prior art.Described radiator is made of flat tube 9 and fin 1, and described fin is a fin type, and the thickness of fin fin can be between 0.1～0.4mm, and described flat tube 9 and fin 1 are monolithic construction.The fin fin processes on the aluminium flat board, and then moulding flat tube 9 structures.Being provided with insulating barrier 2,3 around the inwall of the flat tube 9 of described radiator, is to be provided with insulating barrier between battery lead plate 7 and fin slices radiator.In order further to increase the radiating effect of radiator, respectively there is a sulculus 5 the radiator two sides, are provided with the step 8 of protrusion at the lumen of radiator wall.Described ceramic PTC element 4 places described flat tube 9, and with battery lead plate 7 between adopt bonding way to connect, adhesives can be organic silica gel or other bonding agent.
