Description

A kind of forming frock of the heat sink strip of PTC thermo-sensitive material heating device

Technical field

The utility model belongs to thermal sensitive ceramics manufacturing technology field, and especially a kind of PTC thermo-sensitive material heating device dissipates The forming frock of hot item.

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: in view of the shortcomings of the prior art, the utility model provides a kind of PTC thermo-sensitive material heating devices Heat sink strip forming frock.

Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this: a kind of The forming frock of the heat sink strip of PTC thermo-sensitive material heating device, platen, clamping and fixed heat sink strip including placement heat sink strip Posting；The platen is processed L-shaped in the width direction, and there are rectangular recess, the side of length direction in width direction surface There is a no less than composing type to fasten cylinder, the posting by width and the heat sink strip it is of same size, be highly 15 ~ 50mm Two rectangular metal items and no less than two groups of slide fasteners composition.

Wherein, the slide fastener is made of the sheet metal and connection fixture of U-shaped, two wings of the U-shaped sheet metal Long of same size with the platen, wing width is 8 ~ 35mm, and wall thickness is 4 ~ 20mm, U-shaped sheet metal bottom connected component Two wing spans are of same size with the rectangular metal item, secondly being provided with location hole in the wing plane of wing upper end.

Wherein, the connection fixture of the slide fastener is that width and the identical rectangular metal of the rectangular metal item are fixed There are screw hole in position block, the centre of the locating piece, and there is the upper end wing plane that can be embedded in positioned at the U-shaped sheet metal at the both ends of locating piece On positioning hole limit salient point.

The utility model has the advantages that the utility model compared with traditional technology, has the advantages that

(1) the utility model scientific structure design, be easy to control, high yield rate, manufacturing cost it is also low；

(2) the utility model can complete the clamping work of heat sink strip well, be clamped after heat sink strip assembling, Until being detached from after baking molding, entire process can guarantee that each component of heat sink strip is not scattered, and operative employee is facilitated to manipulate.
