Description
Technical field
The invention belongs to thermal sensitive ceramics manufacturing technology field, especially a kind of heat sink strip of PTC thermo-sensitive material heating device
And heating device and dedicated electric appliance.
Background technique
Patent enclosed positive temperature coefficient thermistor heater, the patent No. 200620034186, ripple are S-shapeds, although
It is advantageous to improve condensation, but S type cooling fin and trapezoidal reinforcing rib can not be formed and be produced in batches, even if craft or 3D draw a design out
Sample, not can avoid because needing to make itself and weld tabs not to open when being sufficiently bonded just and can guarantee in vacuum welding yet, desoldering due to right
Bring deforms when clamping the pressurization of fixinig plate up and down of ripple bar, distortion equal strength is low and the defect of failure welding.
Furthermore such as patent corrugated fins item, the patent No. 201320036750.5 are disclosed using with the two-sided of solder
Composite band, material cost is more than 1 times or more that common aluminium flake adds soldering weldering foil, since the temperature of welding is much higher than the molten of weldering foil
Point temperature, manufacturing cost is high, is also easy desoldering.In addition the technology is further simultaneously disclosed using spot welding, ultrasonic bonding, Laser Welding
Etc. techniques, these techniques have the defects that the poor bonding strength between the radiatinig corrugated of heat sink strip and thermally conductive sheet.If using
The technique for sticking, although manufacturing cost is low, since in the manufacturing process of heater, radiatinig corrugated and thermally conductive sheet are combined
Heat sink strip and fever tablet between have to form simultaneously, hot setting, these will all be completed by hand, can not form scale
Production, low efficiency, manufacturing cost are also high.
Air-conditioning be used for a long time in winter shutdown after, the heatsink temperature of heater be rapidly decreased to from 100 DEG C or so 0 DEG C with
Under, frosting can be led to because of the variation of environment temperature in this moment, when room temperature is raised to 0 DEG C or more, because the thawing of frost forms water droplet
Accumulation forms condensation on a heat sink.Since its radiating surface of the radiatinig corrugated of prior art is continuous level no concave-convex knot
Structure, the frost or water droplet of condensation can accumulate in bottom along heating plane, thus there is the heat exchange wind of secondary booting operating instant
Product is attached to the hidden danger of the water droplet blowout on radiatinig corrugated surface, leads to customer complaint.
Summary of the invention
Goal of the invention: the present invention can not be formed and be produced in batches for traditional heat-dissipating S type cooling fin and trapezoidal reinforcing rib,
Not can avoid because needing to make itself and weld tabs not to open when sufficiently be bonded just and can guarantee in vacuum welding, desoldering due to clamping ripple bar
The pressurization of fixinig plate up and down when bring deformation, equal strength is low and the defect of failure welding for distortion, manufacturing cost is high, is easy de-
Weldering the problem of the defect of the poor bonding strength between radiatinig corrugated and thermally conductive sheet, provides a kind of PTC thermo-sensitive material heating device
Heat sink strip.
The second object of the present invention is to provide the heating device containing PTC thermo-sensitive material.
The third object of the present invention is to provide the dedicated electric appliance using above-mentioned heat sink strip.
Technical solution: in order to achieve the above object of the invention, the present invention is specifically achieved like this: a kind of PTC temperature-sensitive material
The heat sink strip for expecting heating device, including the radiatinig corrugated clamped by thermally conductive plain film and flanging positioning thermally conductive sheet, the heat dissipation wave
Line has a no less than folded angular surface along the short transverse of radiating surface, and the width direction of the folded angular surface and the radiatinig corrugated is hung down
Directly.
A kind of heating device of PTC thermo-sensitive material, contains above-mentioned heat sink strip.
Wherein, the heating device includes PTC heater element, and the principal component of the PTC heater element is Ba(1-x)
PbxTiO3, the Ti are rutile TiO_2 raw ore through refining, and the molar ratio of Ti is greater than 1.00% in the principal component.
Wherein, the heating device includes PTC heater, and the heater is to have penetrated in hollow heat-conducting aluminium pipe by exhausted
Velum cladding between two strip electrode pieces it is in parallel pasted the heat generating core of PTC temperature-sensitive heater element after, repressed aluminum pipe it is thermally conductive
Face eliminates the gap of the intracorporal heat generating core of the fever and the aluminum pipe inner wall, forms the PTC heater of surface insulation,
The aluminum pipe heat-transfer surface of the heater forms the PTC thermo-sensitive material heating device after being bonded the heat sink strip.
A kind of electric appliance, the heating device containing any of the above-described kind of PTC thermo-sensitive material.
Wherein, the electric appliance be selected from air-conditioning, warm-air drier, hot air curtain device, super bath, dehumidifier, air purifier, dryer,
One kind of automobile warm-air or demisting defroster.
The utility model has the advantages that the present invention compared with traditional technology, has the advantages that
(1) radiatinig corrugated face of the present invention is designed as folded angular surface, can make the accumulation of minor amount of water drop and be contained in the dog-ear
In face, the moment after secondary booting is not blown out, and as the moment of heating device generates heat, micro condensing drip is heated immediately
Volatilization, effectively improves use environment, improves comforts of use and environment-friendly function, additionally due to the molding of heating device
Need to apply the radiating surface of heat sink strip biggish pressing force in journey to guarantee to make to be fitted in the PTC temperature-sensitive heater on radiating surface
Integrally combine between heat sink strip, reaches optimal heat dissipation effect and the thermal efficiency, the beveled structure of radiatinig corrugated of the invention is also
The radiating surface of heat sink strip can be made in the forming and hardening of heating device, will not be become when by pressing force perpendicular to radiatinig corrugated
Shape greatly increases the intensity of heat sink strip;
(2) droplet that frosting condensation generates is natural, disperse, irregular shunting is in folded angular surface, in repeated priming moment, because dissipating
It is heated rapidly on backing without droplet and heater, it can be ensured that not only blew out without water droplet but also product can be attached in folded angular surface rapidly
Water droplet dryouies, and is commercialized and answers comprehensively on air-conditioning so as to the puzzled air-conditioning producer of effective solution and influence thermal sensitive ceramic heater
The problem of repeated priming moment blows out water droplet because of condensation;
(3) heat dissipation area of folded angular surface is far longer than prior art, greatly improves the heat dissipation area and the thermal efficiency of heater,
It is structurally equivalent to add reinforcing rib to radiatinig corrugated, substantially improves and improve the intensity of heater, due to the water of frosting
Drop can simultaneously, in each folded angular surface of the irregular height for being diverted to radiatinig corrugated radiating surface and width direction, effectively subtract
Lack subtle droplet existing for prior art and concentrates the defect for converging in bottom formation ponding or large water droplet;
(4) simple production process, be easy to control, high yield rate, manufacturing cost it is also low;
(5) this technology uses 1.0% mole or more excessive Ti2O3, ensure that the content of Ti in formula in 1, ensure that formula
The superiority of stability and electrical property, by the PTC heater element of this formula production, yield rate reaches 98% or more, and the heat of element is steady
It is qualitative it is good, interpolar is high pressure resistant, especially suitable for requiring in the electric equipment products such as relatively high air-conditioning heater service performance.
