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

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
