[embodiment]
With reference to Fig. 1, Fig. 2, present embodiment is described.Fig. 1 is the vertical view of the well heater representing embodiment.Fig. 2 is the key diagram of the relation represented between silver and temperature-coefficient of electrical resistance.Silver-colored ratio [% by weight] in Fig. 2 is silver-colored ratio when resistance heater being set to 100 % by weight.
The well heater 1A of present embodiment is installed in electronic equipment class, mainly heats media such as the paper passed through.As shown in Figure 1, well heater 1A is configured to comprise: substrate 2, conductor 3, resistance heater 4, a pair power consumption pole 5,6, outer jacket 7.
Substrate 2 has thermotolerance and insulativity, is formed as rectangular-shaped in the present embodiment.The flat board of substrate 2 such as being made up of pottery, heat-resisting composites etc. such as aluminium oxide.Substrate 2 have with can the corresponding thickness in the space of mounting heater 1A, such as about 0.5mm ~ 1.0mm.In addition, as long as the long side direction having short side direction and intersect with short side direction, the shape of substrate 2 does not limit for this reason, can form recess, protuberance, otch in periphery yet.
Conductor 3 for supplying power to resistance heater 4, and is formed on a substrate 2.Conductor 3 in present embodiment (hreinafter referred to as " long side direction ") on the long side direction of well heater 1A (substrate 2) is electrically connected with resistance heater 4.Conductor 31 included by conductor 3 and conductor 32, conductor 33 are separately formed on long side direction, are configured with resistance heater 41,42 therebetween respectively.Conductor 31 is formed along the long side direction of resistance heater 41, and one side end is electrically connected with power consumption pole 5, and end side is electrically connected with a side end of resistance heater 41.Conductor 32 is formed along the long side direction of resistance heater 42, and one side end is electrically connected with power consumption pole 6, and end side is electrically connected with a side end of resistance heater 42.Conductor 33 is electrically connected with the end side of resistance heater 41,42 respectively.That is, conductor 3 is electrically connected along the long side direction of resistance heater 4.
Conductor 3 in present embodiment is using silver (Ag) as major component.At this, so-called major component refers to the material accounting for main by weight % in the material forming conductor 3.Therefore, in conductor 3, the total of silver and adjuvant almost becomes 100 % by weight.Conductor 3, due to containing adjuvant, thus can suppress silver to spread to resistance heater 4.
Conductor 3 is formed as follows: by containing above-mentioned substance, resistance value is enough low compared with resistance heater 4 conductor paste to be coated on substrate 2 and to burn till.At this, so-called " coating ", as long as conductor paste can be coated on substrate 2, any mode, comprises screen painting.
Resistance heater 4 is electrically connected with conductor 3, and generates heat by being energized, and is formed on substrate 2.In the present embodiment, resistance heater 4 is formed along long side direction.Resistance heater 41 included by resistance heater 4, resistance heater 42 are separately formed on short side direction.Resistance heater 41,42 is formed as the band shape along long side direction respectively, and the consistent length on the short side direction of its well heater 1A (hreinafter referred to as " short side direction ").
The resistance heater 4 of present embodiment contains: ruthenium-oxide (RuO
4); Glass; Comprise titanium dioxide (TiO
2), manganese oxide (MnO
2) and iron oxide (FeO, Fe
2o
3, Fe
3o
4) potpourri; Silver (Ag).Resistance heater slurry containing above-mentioned substance is coated on substrate 2 and is formed by resistance heater 4.In resistance heater 4, ruthenium-oxide, glass, potpourri, silver almost account for 100 % by weight.The glass of resistance heater 4 containing softening point higher (such as, 600 DEG C ~ 800 DEG C).As shown in Figure 2, in resistance heater 4, when entirety is set to 100 % by weight, silver accounts for less than 1 % by weight to 8 % by weight, and glass accounts for about 2 times of potpourri, and ruthenium-oxide accounts for about 2.5 times of glass.At this, why silver accounts for less than 1 % by weight to 8 % by weight is to make temperature-coefficient of electrical resistance become less than-800ppm/ DEG C, preferably becomes the scope of-800ppm/ DEG C ~-1050ppm/ DEG C.If temperature-coefficient of electrical resistance exceedes-800ppm/ DEG C, then the effect that suppression paper described later is not risen by the temperature in region can reduce.Therefore, by making silver account for less than 1 % by weight to 8 % by weight, can improve and suppress paper not by effect that the temperature in region rises.
At this, the silver-colored composition of conductor easily spreads in the resistance heater 4 containing ruthenium-oxide.If silver is mixed in the resistance heater 4 of not argentiferous, then between sliver diffusion region and non-diffusion zone, there is the deviation of heater resistance value or temperature-coefficient of electrical resistance.Therefore, by making the silver of resistance heater 4 in advance containing weight ratio more more than the amount (being less than 0.5 % by weight) being mixed into the silver of resistance heater 4 by diffusion, the deviation of heater resistance value or temperature-coefficient of electrical resistance can be suppressed.Thereby, it is possible to form the resistance heater 4 of desired heater resistance value or temperature-coefficient of electrical resistance on a substrate 2.
A pair power consumption pole 5,6 is electrically connected with conductor 3 respectively, and is formed on substrate 2.As shown in Figure 1, a pair power consumption pole 5,6 is formed at the end of substrate 2 on long side direction.A pair power consumption pole 5,6 is electrically connected with conductor 31,32 respectively, is energized with conductor 31,32.In addition, in Fig. 1, a pair power consumption pole 5,6 is formed in a side end of substrate 2, but also can be formed at both ends respectively, can also be formed at end side.And a pair power consumption pole 5,6 is integrally formed on substrate 2 with conductor 31,32 usually respectively, but formation can be opened with conductor 31,32 points respectively in a pair power consumption pole 5,6.And, the formation surface being formed with conductor 31,32 on a substrate 2, a pair power consumption pole 5,6, but also can be formed at on the face of conductor 31,32 forming surface opposite side.Now, a pair power consumption pole 5,6 is electrically connected with conductor 31,32 respectively by the perforation being formed at substrate 2.
Outer jacket 7 is protective seams, is formed at conductor 3 on substrate 2 and resistance heater 4 for covering, and is formed as banded in the present embodiment.Because outer jacket 7 covers conductor 3 and resistance heater 4, therefore conductor 3 and resistance heater 4 is prevented directly to be exposed in air, suppress conductor 3 and resistance heater 4 to be subject to the interference (such as, mechanicalness, chemically, electrically interfere) from outside and damage, damaged.It is high that outer jacket 7 is formed as thermal conductivity ratio substrate 2, such as, with the addition of the glassy layer of the superior inorganic oxide filler 25 ~ 35 % by weight of the heat conductivities such as the aluminium oxide of more than 2 [W/ (mk)].
Then, the operation of well heater 1A is described.Well heater 1A is powered from outside by a pair power consumption pole 5,6.If well heater 1A is powered, then conductor 3 is energized, and the resistance heater 41 between conductor 31,33 and the resistance heater 42 between conductor 32,33 are energized respectively on long side direction.Thus, resistance heater 41,42 generates heat respectively, and well heater 1A is in the almost whole region heating of long side direction.
As mentioned above, in the well heater 1A involved by present embodiment, the resistance heater 4 containing ruthenium-oxide has NTC characteristic.As the resistance heater with NTC characteristic, there is a kind of heater containing graphite.Glass containing the glass comprised in the resistance heater of graphite and formation outer jacket uses the glass that softening point is lower.And the reactivity of graphite to softening glass is higher, produce carbon dioxide (CO by reaction
2).That is, such as produce carbon dioxide when the resistance heater formed coating burns till, graphite burns from substrate.Therefore, preferably do not use the material containing graphite as the resistance heater of well heater.On the other hand, ruthenium-oxide is lower to the reactivity of softening glass when high temperature.Compared with the resistance heater containing graphite, the resistance heater 4 containing ruthenium-oxide can use the glass of softening point higher (such as, 600 DEG C ~ about 800 DEG C).Therefore, can use in well heater 1A the lower ruthenium-oxide of the reactivity of glass, glass that softening point is higher.That is, such as can not produce carbon dioxide when the resistance heater formed coating burns till, can not burn from substrate as resistance heater during resistance heater as use graphite.Therefore, preferential oxidation ruthenium is as the resistance heater of well heater.
In addition, in the above-described embodiment, conductor 3 is electrically connected with resistance heater 4 on long side direction, but is not only limited to this.Fig. 3 is the vertical view of the variation of the well heater representing embodiment.As shown in Figure 3, in well heater 1B, conductor 8 and resistance heater 9 are electrically connected direction not at long side direction.Conductor 3 and the resistance heater 4 of the conductor 8 of well heater 1B and resistance heater 9 and well heater 1A are that shape is different respectively, its constituent material, % by weight etc. then identical.

Resistance heater 9 is formed along long side direction as a whole.Resistance heater 91 ~ 95 included by resistance heater 9 is separately formed on long side direction, namely configures along long side direction.Resistance heater 91 ~ 95 to be formed as on long side direction long rectangular-shaped respectively, and the consistent length on its short side direction.
Then, the action of well heater 1B is described.Well heater 1B is powered from outside by a pair power consumption pole 5,6.If well heater 1B is powered, then conductor 8 is energized, and the resistance heater 94 between the resistance heater 93 between the resistance heater 92 between the resistance heater 91 between conductor 84,85, conductor 85,86, conductor 86,87, conductor 87,88 and the resistance heater 95 between conductor 88,82 are energized respectively on short side direction.Thus, resistance heater 91 ~ 95 generates heat respectively, and well heater 1B is in long side direction almost whole region heating.
