Hot item 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 to be sufficiently bonded just due to can guarantee in vacuum welding Shi Bukai, desoldering right yet
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.
Utility model content
Purpose of utility model: the utility model for traditional heat-dissipating S type cooling fin and trapezoidal reinforcing rib can not batch at
Type and production not can avoid because needing to be bonded itself and weld tabs sufficiently just due to can guarantee in vacuum welding Shi Bukai, desoldering 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, manufacturing cost
The problem of height, easy desoldering, the defect of the poor bonding strength between radiatinig corrugated and thermally conductive sheet, provide a kind of PTC thermo-sensitive material
The heat sink strip of heating device.
The second of the utility model is designed to provide the heating device containing PTC thermo-sensitive material.
The third of the utility model is designed to provide the dedicated electric appliance using above-mentioned heat sink strip.
Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this: a kind of
The heat sink strip of PTC thermo-sensitive material heating device, including the radiatinig corrugated clamped by thermally conductive plain film and flanging positioning thermally conductive sheet, institute
It states the short transverse of radiatinig corrugated while there is concave face and folding fan face, the concave face and folded angular surface and the radiatinig corrugated
Width direction is vertical.
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 utility model compared with traditional technology, has the advantages that
(1) radiatinig corrugated face described in the utility model is designed as concave shape or turns up face, can make minor amount of water drop accumulation and
It being contained in the groove or turns up in face, the moment after secondary booting is not blown out, as the moment of heating device generates heat,
Micro condensing drip is heated volatilization immediately, effectively improves use environment, improves comforts of use and environment-friendly function, this
Outside due to needing the radiating surface to heat sink strip to apply biggish pressing force to guarantee to make to be fitted in the forming process of heating device
PTC temperature-sensitive heater on radiating surface and integrally combine between heat sink strip, reach optimal heat dissipation effect and the thermal efficiency, this is practical
The bumps of novel radiatinig corrugated or the structure for turning up face can also make the radiating surface of heat sink strip in the forming and hardening of heating device,
It will not be deformed when by pressing force perpendicular to radiatinig corrugated, greatly increase the intensity of heat sink strip;
(2) droplet that frosting condensation generates is natural, disperse, irregular shunting is in concave face or serrated face and recess and saw
In the faying face of tooth, in repeated priming moment, because being heated rapidly on cooling fin without droplet and heater, it can be ensured that both without water droplet
Blowout can rapidly dryout the water droplet that is attached in recess or serrated face of product again, so as to effective solution puzzle air-conditioning producer and
Thermal sensitive ceramic heater is influenced the problem of the repeated priming moment of commercial applications comprehensive on air-conditioning blowing out water droplet because of condensation;
(3) heat dissipation area of the faying face of concave face, serrated face, recess and sawtooth is far longer than prior art, greatly
Improve the heat dissipation area and the thermal efficiency of heater.Be structurally equivalent to add reinforcing rib to radiatinig corrugated, substantially improve and
Improve the intensity of heater.Due to frosting water droplet can simultaneously, the irregular height for being diverted to radiatinig corrugated radiating surface and
In each concave face of width direction, it is effectively reduced the concentration of subtle droplet existing for prior art and converges in bottom and form product
The defect of water or large water droplet;
(4) simple production process, be easy to control, high yield rate, manufacturing cost it is also low.
