Description

A kind of rotary propeller type PTC fever tablets

Technical field

This utility model belongs to PTC heatings field, especially arranges a kind of area of dissipation greatly, the high PTC heatings of heating power Piece.

Background technology

PTC heaters, are a kind of ceramic materials, can be with temperature automatically controlled.During energization because itself resistance ratio of room temperature compared with It is little, therefore initial current is larger, and PTC heaters can be made heating up quickly, causes resistance value itself to increase sharply and enters transition Area, the electric current that can pass through PTC heaters this moment are just very little so that the moderate holding steady state value of PTC heater surface temperatures, and this is permanent Constant temperature degree is only relevant with the Curie temperature and applied voltage of PTC heaters, and substantially unrelated with ambient temperature.

Using this characteristic, in actual life use extremely extensive, be directly to use as pyrotoxin, such as directly Send out device, curler, warmer, thermal therapeutic apparatus, electric hot tray etc..But such use is all the relatively not high product of power, typically All in below 5000W, for high-power industrial water heaters, then its requirement cannot be met.

Utility model content

Technical problem to be solved in the utility model is to provide one kind and has heat conduction power very high, greatly can expire The PTC fever tablets of the demand of the high-power heat-emitting products of foot.

To solve the above problems, the technical scheme of this practical utility model is, a kind of rotary propeller type PTC fever tablets, including PTC Heater and heat conduction section bar, the heat conduction section bar include three, and the end of three heat conduction section bars links into an integrated entity in " rotation oar " shape； Single PTC heaters and two panels electrode slice are provided with the single heat conduction section bar, electrode slice is affixed on the upper of the PTC heaters Lower two surfaces, and the electrode slice derived by resistant to elevated temperatures wire.

Further, electrode slice applies mechanically sleeve pipe with the connecting position of wires.

Further, described sleeve pipe is any one in heat-shrinkable T bush, silica gel sleeve pipe or the outer gum cover pipe of interior fibre.

Further, the heat conduction section bar is aluminum heat conduction section bar.

The beneficial effects of the utility model：As the heat conduction section bar includes three, the end connection of three heat conduction section bars It is integral in " rotation oar " shape；Single PTC heaters and two panels electrode slice are provided with the single heat conduction section bar, so that institute PTC heaters are stated during heating, area of dissipation is greatly increased, also allow for heating power and be greatly improved, Meet the demand of industrial heat.

Description of the drawings

The structural representation that Fig. 1 is provided for this utility model；

Specific embodiment

This utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.

As described in Figure 1, a kind of PTC fever tablets, including PTC heaters 1 and heat conduction section bar 2, the heat conduction section bar 2 include three Piece, the end of three heat conduction section bars 2 link into an integrated entity in " rotation oar " shape, and heat conduction section bar 2 is aluminum heat conduction section bar.It is described single to lead Single PTC heaters 1 and two panels electrode slice are provided with hot profiles 2, electrode slice is affixed on two up and down of the PTC heaters 1 Surface, and the electrode slice derived by resistant to elevated temperatures wire.Electrode slice applies mechanically sleeve pipe with the connecting position of wires.The set Manage as any one in heat-shrinkable T bush, silica gel sleeve pipe or the outer gum cover pipe of interior fibre so that connection is more firm, be difficult disconnection.

The PTC heaters 1 are loaded in heat conduction section bar 2, is then connected by the electrode slice with wire, and is adopted Three " rotation oar " shape structures, i.e., when after wire connected power, then fax is also immediately directed at electrode slice the institute of respective connection State PTC heaters 1, therefore three PTC heaters 1 generate heat simultaneously, and by heat by the heat conduction section bar 2 of each periphery to Surrounding disperses, and the heat conduction section bar 2 not only has fabulous conduction effect, and the design of three " rotation oar " shape structures greatly increases The area of radiating, so that three PTC heaters 1 produce more heats, and in time and quickly conducts heat, Heat conduction power is greatly improved, is met in industry to high-power demand.

One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this reality With new principle, it should be understood that protection domain of the present utility model is not limited to such especially statement and embodiment. One of ordinary skill in the art these technology enlightenments can make various without departing from this practicality according to disclosed in this utility model New other substantive various concrete deformations and combination, these deformations and combination are still in protection domain of the present utility model.
