Abstract
The utility model relates to a PTC heating assembly for clothes dryers. A PTC element is fixedly connected by silicon rubber according to the sequence of one corrugated heat dispersion strip 2 with single strip, the PTC element 1, and another corrugated heat dispersion strip 2 with single strip and is solidified between heat dispersion strips 2. One end of the frames of two heat dispersion strips is respectively connected with a stainless steel single terminal 4. The utility model not consume indoor oxygen in heating. The utility model has the advantages of long service life, high heat and electricity conversion efficiency, and obvious electricity saving. Because the PTC element heats in automatic temperature limit, the utility model effectively avoids the disaster outcomes of built-in plastic part softening, dry clothing deformation or burning, etc. caused by over high temperature, and the utility model is very safe.
Description
The utility model belongs to a kind of novel heater, is specifically related to a kind of PTC heating component that is used for dryer.
Conventional electric heating type dryer is made heater with heating wire or electrothermal tube traditionally.Though heating wire or electrothermal tube cost are lower, easily oxidation of surface consumes the oxygen in the room air, and useful life is short; And electric heating conversion efficiency is low, and power consumption is big; Owing to can not easily cause plastic parts softening transform in the dryer, by drying composition deformation or burning from the limit temperature in actual use.
The purpose of this utility model is to provide a kind of heating wire or the novel heater of electrothermal tube--PTC heating component that is used for substituting dryer heating usefulness.
PTC heating component of the present utility model, it is characterized in that by wall scroll ripple heat sink strip, the PTC element, the order of wall scroll ripple heat sink strip, with silicon rubber that the PTC element is fixedly connected and at high temperature be solidificated in the middle of the heat sink strip, each bag of an end at the frame of two heat sink strips connects a stainless steel single terminal, described wall scroll ripple heat sink strip is to be that the thickness of slab that the vacuum hot weld has the annealed state aluminium alloy to be made between the half-hard state single face vacuum brazing clad aluminium outer rim of 0.45～0.9mm and the interior frame is the radiatinig corrugated of 0.15～0.4mm at a thickness of slab, and its ripple density is that two adjacent wave line centre-to-centre spacing r are 1.3～6.0mm; Described PTC element is that a kind of Curie temperature is that 180-270 ℃, thickness are the BaTiO of 1.8～3.8mm
3Base thermal sensitive ceramics resistance.
Described PTC element is a kind of semistor.
The width of PTC element should with the heat sink strip size match; The integer multiple of its length be slightly less than heat radiation band corrugated portion length (1.0～2.0mm), its quantity heats power requirement according to machine and decides.
The watt level of PTC heating component is relevant with ripple density with the seal ring thickness of thickness, Curie temperature and the heat sink strip of PTC element.Generally, the Curie temperature of PTC element is high more or reduce the thickness of PTC element, and the power of this PTC element is just big; Increase the ripple density of heat sink strip or reduce the seal ring thickness of heat sink strip, also can improve the heating power of PTC heating component.As shown in the table, the seal ring thickness of the thickness of choose reasonable PTC element, Curie temperature and heat sink strip and ripple density just can obtain the PTC heating component of the good power demand of fail safe.
Embodiment
| Embodiment | Heat sink strip | The PTC element | Power W | Fail safe | ||
| Seal ring thickness mm | Ripple density mm | Thickness mm | Curie temperature ℃ | |||
| Electrothermal tube | Do not have | Electrothermal tube | 450-600 | Difference | ||
| Example 1 | 0.45 | 1.3 | 3.8 | 130 | 350-600 | Good |

| Example 3 | 0.95 | 6.0 | 1.8 | 290 | 300-500 | Difference |
When practical application, the PTC heat generating component is installed in the import or export position in air channel, behind the fan starting, wind blows out by the heat sink strip of PTC heat generating component; Under the situation of PTC heat generating component energising, the ripple in cold wind and the heat sink strip carries out heat exchange, and heat is brought in the cavity, reaches the effect of drying.
This PTC heating component adstante febre does not consume indoor oxygen, long service life, and also electric heating conversion efficiency height, economize on electricity are significantly; Because the PTC element is from limit temperature heating, thus avoided effectively Yin Wendu too high and in the machine that causes plastic parts softening and by disaster consequences such as drying composition deformation or burnings, fool proof.
Below in conjunction with accompanying drawing PTC heating component of the present utility model is described further:
Fig. 1 is the structural representation of the utility model PTC heating component.
Fig. 2 is the vertical view of the utility model PTC heating component.
As depicted in figs. 1 and 2, PTC heating component of the present utility model, press wall scroll ripple heat sink strip 2, PTC element 1, the order of wall scroll ripple heat sink strip 2, with silicon rubber that PTC element 1 is fixedly connected and at high temperature be solidificated in the middle of the heat sink strip 2, each bag of an end at the frame of two heat sink strips connects a stainless steel single terminal 4, described wall scroll ripple heat sink strip 2 is to be that the thickness of slab that the vacuum hot weld has the annealed state aluminium alloy to be made between the half-hard state single face vacuum brazing clad aluminium outer rim 2-1 of 0.45～0.9mm and the interior frame 2-2 is the radiatinig corrugated 5 of 0.15～0.4mm at a thickness of slab, and its ripple density is that two adjacent wave line centre-to-centre spacing r are 1.3～6.0mm; Described PTC element is that a kind of Curie temperature is that 180～270 ℃, thickness are the BaTiO of 1.8～3.8mm
3Base thermal sensitive ceramics resistance.
