The film threading type radiator selects and purchases the skill

Believed that everybody is quite familiar to the radiator, then how many film threading type radiator you do know? Actually the film threading type radiator uses the weld joint, the welding quality quality immediate influence film threading type radiator's quality and the service life. Below we introduced:Film threading type radiatorTechnique of production as well asFilm threading type radiation Selects and purchases the skill 。

Anything is the film threading type radiator

The film threading type radiator's different part is with the weld joint, the welding quality quality immediate influence film threading type radiator's quality and the service life. The welding process mainly has the filling material to weld welds with the main body, relatively speaking, the main body welds the inoxidizability is good, and has welds the scar evenly together, cannot polish; The filling material welds the inoxidizability is bad, surface after polish smooth smooth.

When purchase mainly looked that it welds to be whether reliable, the outward appearance welded joint to be whether even, has the uneven phenomenon. But, cannot too demand the welded joint smoothly smooth, because excessive polish processing easy to create the welding position the intensity to reduce, causes to run the water leakage.

Film threading type radiator technique of production

First, when regarding high-density tooth and tongue compared to big mold experimental mold, the first aluminum stick must be the 150-200mm short aluminum stick or the pure aluminum stick.

Second, before the experimental mold, must adjust the good extrusion core, pushes the next to last act, Sheng Dingtong and the die bed discharge hole in a middle line.

Third, in experimental mold and in the regular production process, the aluminum stick heating temperature must guarantee in 480-520℃ between.

Fourth, the mold heating temperature according to the conventional mold temperature, checks in 480℃ about, the diameter 200mm following outline templet soaking time do not be short in 2 hours, if is diverges the mold heat preservation above 3 hours; The diameter is bigger than the 200mm above mold to keep warm for 4-6 hour, guarantees the mold core section temperature and exterior temperature even.

Fifth, before the experimental mold or the production, must use in clear cylinder pad cleaning up clean Sheng Dingtong the gallbladder, and examined that the extruder runs emptily whether normally.

Sixth, the experimental mold or just started when produces, the extruder automated files switch off, each section of switches turn over to the zero position. Starts slowly from the minimum pressure to press, leaves the material probably 3-5 minute, when the aluminum packing process the primary control good pressure. The pressure control in 100Kg/cm2, the ampere meter data is in 2-3A, generally 80-120Kg/cm2 may leave the material, afterward only then may the acceleration slowly, when the regular production extrudes the speed is smaller than take the pressure 120Kg/cm2 as the standard.

Seventh, the mold when the experimental mold or in the production process, like the detection stops up the mold, the leaning tooth, the rate deviation is too big and so on phenomena must immediately the engine off, and the mode which draws back by the point unloads the mold, avoids the mold abandonment.

Eighth, in the experimental mold or in the production process, the discharge hole must be unobstructed, advances money or the jig slackens off the basis to leave the material situation to grasp reasonably. Momentarily observation detection unusual circumstance, stitch in time, when this engine off must immediately the engine off.

The film threading type radiator selects and purchases the skill

We in selection film threading type radiator's time must first be clear about radiator's use use, then carries on the selection according to the product characteristic.

1st, the radiator effect fit and unfit quality with install the craft to have the close relation, installs when should increase the power component and radiator's contacted area as far as possible, reduces the contact thermal resistance, enhances the heat transfer effect.

2nd, needs when the component and the radiator the pad heat conduction or the insulation spacer, recommended that uses the low thermal resistance material, like purple copperfoil, aluminum platinum or thin mica, polyester thin film.

3rd, when installs a component, its installment hole (or group hole) puts in the radiator basic plane the core (L/2) the position; When installs two either two above spiral disc heat interchangers its installment hole (or group hole) position in radiator basic plane middle line even cloth (L/2n) position.

4th, fastens when the component must guarantee that the bolt torsion is consistent.

5th, after the power component and the radiator install, is not suitable again and disperses to the power component carries on the machine-finishing or tidies up, will otherwise have the stress, will increase contacts the thermal resistance heat.

6th, one-sided rib piece type radiator, is suitable for outside the device (for example to install outside case) makes the natural forced-air cooling, namely favors the power component to ventilate the radiation to be possible to reduce within the aircraft the temperature rise.

7th, when natural cooling, should cause radiator's cross section to be parallel to the horizontal plane direction; When forces the forced-air cooling, should cause the air current to flow is parallel to radiator's rib piece direction.
