Abstract
The utility model discloses an annular PTC (positive temperature coefficient) heater. The heater comprises a plurality of circles of radiating rings and PTC ceramic heating bodies which are arranged between adjacent two circles of radiating rings, wherein the radiating rings are polygonal or round; a connecting wire is led from each circle of radiating rings; and PTC ceramic heating bodies are arranged in parallel. When the heater is matched with a round wind wheel to work, due to the adoption of an annular structure and due to the fact that a heating part is isolated from a motor in the middle, materials can be saved, the cost is reduced, the stability and the service life of the motor are ensured, heat is facilitated to be transferred and radiated to air, and the utilization efficiency of the heat is higher.
Description
Technical field
The utility model relates to a kind of ring-type ptc heater.
Background technology
PTC heater is generally used in the heating systems such as warm-air drier.Existing PTC heater mostly is greatly square solid construction, and the PTC heater of this structure and circular wind wheel are complementary when using, and four jiaos and core can't directly blow to wind, and it is inhomogeneous to dispel the heat, and has caused the waste of a large amount of thermal loss and material; And middle heater is directly facing to motor, life-span of motor and stability caused have a strong impact on.On processing technology, existing fin is to cross together soldering all-in-one-piece between high temperature slice electrode holder vent rib and the heat dispersion substrate, and vent rib and heat dispersion substrate have a lot of solder joints, it is the line contact between vent rib and the heat dispersion substrate, heat transfer area is little, and thermal transmission coefficient is low, poor thermal efficiency.
The utility model content
Technical problem to be solved in the utility model provides that a kind of cost is low, heat utilization efficiency is high, and can ensure the stability of motor and the ring-type ptc heater in life-span.
In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of ring-type ptc heater comprises the multi-turn heat dissipating ring, and is arranged on the PTC ceramic heating element between the two adjacent rings heat dissipating ring; Described heat dissipating ring is polygon or circle; All draw wiring on described every circle heat dissipating ring; The described PTC ceramic heating element that respectively encloses is arranged in parallel.
Described heat dissipating ring comprises heat dispersion substrate and vent rib, and heat dispersion substrate and vent rib are the integral type structure, adopts the Aluminum extrusion moulding process to make, or adopts compression molding process to make, or makes by the technique of dedicated tool cutting forming.
Described PTC ceramic heating element is the integral type structure, perhaps has the PTC ceramic heating plate more than two or two to be formed in parallel.
After having adopted technique scheme, the utlity model has following beneficial effect: when (1) the utility model cooperates circular wind wheel work, owing to adopt circulus, motor in the middle of heating part has been avoided, not only can economical with materials, reduce cost, ensure stability and the life-span of motor, and more be conducive to heat conduction and be diffused in the air, heating efficiency is higher.
(2) the PTC ceramic heating element that respectively encloses of the present utility model is arranged in parallel, and by break-make the working quantity of PTC ceramic heating element is selected, can regulating power size, realize the stepping regulatory function.
(3) heat dispersion substrate of heat dissipating ring of the present utility model and vent rib are the integral type structure, and this structure has increased the contact area of the two, thereby have increased heat transfer area, have improved heat transfer efficiency.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model.
Label in the accompanying drawing is:
Heat dissipating ring 1, PTC ceramic heating element 2.
Embodiment
(embodiment 1)
See Fig. 1, the ring-type ptc heater of present embodiment comprises multi-turn heat dissipating ring 1, and is arranged on the PTC ceramic heating element 2 between the two adjacent rings heat dissipating ring 1.
During work, ring-type ptc heater and circular wind wheel are used, can make wind that wind wheel produces by boasting all by whole PTC heater, motor in the middle of heating part has been avoided, not only can economical with materials, reduce cost, ensure stability and the life-span of motor, and more be conducive to heat conduction and be diffused in the air, heating efficiency is higher.By break-make the working quantity of PTC ceramic heating element is selected, can regulating power size, realize the stepping regulatory function.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
