Abstract
The utility model discloses a PTC (positive temperature coefficient) heater band for the electronic element field, comprising a PTC base sheet and a ripple-shaped heat sink strip which is arranged on the surface of the PTC base sheet; and the ripple of the ripple-shaped heat sink strip is a U-shaped ripple. The PTC heater band has the advantages of increasing the radiating area for the ripple-shaped heat sink strip, facilitating radiation of the PTC base sheet, improving the heat efficiency of the PTC heater band, avoiding the appearance of temperature gradient during the radiating process for the PTC base sheet, guaranteeing performance stability when the PTC heater band is used, and improving the service life of the PTC heater band.
Description
Technical field
The utility model relates to a kind of PTC heating plate that is used for field of electrical components.
Background technology
PTC (positive temperature coefficient) heating plate has the characteristic of automatic constant-temperature, and its static working current has only 1/10th of dynamic duty electric current, when its surface temperature reaches Curie temperature, and can automatic constant-temperature.Therefore use the PTC heating plate to do heater element, than the flames of anger in quartz ampoule safety, the reliable and use.The PTC heating plate is difficult for wearing out simultaneously, after using 1000 hours, still can keep good performance.
Present PTC heating plate comprises PTC egative film 1 and corrugated heat sink strip 2; Present said PTC egative film great majority all are that ceramic material is processed; Said PTC egative film 1 surface bonding corrugated heat sink strip 2, the ripple of said corrugated heat sink strip 2 is the V-arrangement ripple, and is as shown in Figure 2.Because the heat conductivility of pottery is poor; And corrugated heat sink strip 2 area of dissipations with V-type ripple are little; Therefore said PTC egative film 1 can not dispel the heat through corrugated heat sink strip 2 fully, therefore causes in the temperature-rise period, said PTC egative film 1 surface meeting appearance temperature gradient; Influence the heat efficiency of PTC heating plate, also influence simultaneously the PTC heating plate in use stable performance and shortened useful life of PTC heating plate.At present in order to guarantee PTC egative film 1 appearance temperature gradient not in temperature-rise period, use the electrical equipment of PTC heating plate to want the circuit of complex design usually, raised production cost of products.
The utility model content
The purpose of the utility model is in order to overcome the deficiency of prior art; A kind of PTC heating plate is provided, and it can solve the bad problem of PTC egative film heat radiation, improves the heat efficiency of PTC heating plate; Guarantee the stable performance in use of PTC heating plate, the useful life of having improved the PTC heating plate.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of PTC heating plate comprises PTC egative film and the corrugated heat sink strip that is arranged at said PTC backsheet surface; The ripple of said corrugated heat sink strip is the U-shaped ripple.
Further, said PTC egative film be shaped as strip, the ripple of said corrugated heat sink strip is arranged along the long axis direction of said PTC egative film.
Further again, the end direction of principal axis of the said PTC egative film in edge is provided with the corrugated heat sink strip that several rows are arranged in parallel.
Further, said corrugated heat sink strip is that aluminium is processed.
Further, the bottom surface of said PTC egative film and end face all are provided with said corrugated heat sink strip.
Adopted the technical scheme of a kind of PTC heating plate of the utility model; Promptly the ripple at the corrugated heat sink strip that is arranged at said PTC backsheet surface is the technical scheme of U-shaped ripple, and its technique effect is: the area of dissipation of corrugated heat sink strip increases, and helps the heat radiation of PTC egative film; Improve the heat efficiency of PTC heating plate; Avoid PTC egative film appearance temperature gradient in the heat radiation process, guarantee the stable performance in use of PTC heating plate, the useful life of having improved the PTC heating plate.

Fig. 2 is the top surface structure sketch map of a kind of PTC heating plate of prior art.
Embodiment
See also Fig. 1,, pass through embodiment particularly below, and combine accompanying drawing at length to explain in order to understand the technical scheme of the utility model better:
A kind of PTC heating plate of the utility model comprises PTC egative film 1 and corrugated heat sink strip 2 among Fig. 1; Said PTC egative film 1 be shaped as strip; On the end face of said PTC egative film 1; Said corrugated heat sink strip 2 is set, and the ripple of said corrugated heat sink strip 2 is arranged along the long axis direction of said PTC egative film 1.The ripple of said corrugated heat sink strip 2 is the U-shaped ripple.The purpose of design is like this: the area of dissipation of corrugated heat sink strip 2 increases; Help the heat radiation of PTC egative film 1; Improve the heat efficiency of PTC heating plate, avoid PTC egative film 1 appearance temperature gradient in the heat radiation process, stable performance and useful life in the use of assurance PTC heating plate.
On the long axis direction of said strip, said corrugated heat sink strip 2, the space width of its ripple are 2.5mm, and the facewidth of said ripple also is 2.5mm.In the process of implementing this technical scheme, the space width of the ripple of said corrugated heat sink strip 2 and the facewidth can be adjusted according to the use needs.
On the short-axis direction of said PTC egative film 1, be provided with the said corrugated heat sink strip 2 that two row are arranged in parallel.Leave the gap between the said corrugated heat sink strip 2 of two row, the purpose of design is further to help PTC egative film 1 to dispel the heat like this, improves the heat efficiency of PTC egative film.
In the bottom surface of said PTC egative film 1 the corrugated heat sink strip 2 identical with the end face of said PTC egative film 1 can be set also, the purpose of design is further to help PTC egative film 1 to dispel the heat like this, improves the heat efficiency of PTC egative film.
In the present embodiment, said corrugated heat sink strip 2 is made of aluminum, and this is taking all factors into consideration from result of use and cost.
In the present embodiment; Said corrugated heat sink strip 2 is the bottom surface or the end faces that are arranged on said PTC egative film 1 of the bonding through silica gel; This is that the mode that said corrugated heat sink strip 2 is habitually practised is set on said PTC egative film 1 at present, but the utility model does not repel other said corrugated heat sink strip 2 is not arranged at the mode on the said PTC egative film 1.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
