2. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   Automobile radiators are constructed of a pair of metal or plastic header tanks, linked by a core with many narrow passageways, giving a high surface area relative to volume. This core is usually made of stacked layers of metal sheet, pressed to form channels and soldered or brazed together. For many years radiators were made from brass or ...

3. Ultrasonic welding of thermoplastics - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_welding_of...

   The materials to be welded experience similar vibrations to those in plunge welding but shorter in time. [3] Hold force to the newly welded region is provided by previously welded section that has come out of the tooling and cooled down. [1] Scan welding is a type of continuous ultrasonic welding in which case large plates or sheets can be ...

4. Radio-frequency welding - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_welding

   Radio-frequency welding, also known as dielectric welding and high-frequency welding, is a plastic welding process that utilizes high-frequency electric fields to induce heating and melting of thermoplastic base materials. [1] The electric field is applied by a pair of electrodes after the parts being joined are clamped together.

5. Laser welding of polymers - Wikipedia

   en.wikipedia.org/wiki/Laser_welding_of_polymers

   Intermediate film welding is a method to join incompatible plastic components by using an intermediate film between them. Similar to transmission welding, laser radiation passes through the transparent components and melts the intermediate layers to create a joint. [ 1 ]

6. Ultrasonic welding - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_welding

   The main obstacle to overcome in this process is the setting of the parameters. For example, if over-welding occurs, then the concentration of plastic in the weld zone may be too low and cause the seal to break. If it is under-welded, the seal is incomplete. [17] Variations in the thicknesses of materials can cause variations in weld quality.

7. Automotive air conditioning - Wikipedia

   en.wikipedia.org/wiki/Automotive_air_conditioning

   The hot, compressed refrigerant vapor is now at a temperature and pressure at which it can be condensed and is routed through a condenser, usually in front of the car's radiator. Here the refrigerant is cooled by air flowing across the condenser coils (originating from the vehicle's movement or from a fan, often the same fan of the cooling ...

8. Friction welding - Wikipedia

   en.wikipedia.org/wiki/Friction_welding

   Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1]

9. Solder alloys - Wikipedia

   Used for fabrication of car radiators and fuel tanks, for coating and bonding of metals for moderate service temperatures. Body solder. Pb 85 Sn 15: 227: 288 [52] Pb: No: Used for coating tubes and sheets and fabrication of car radiators. Body solder. Pb 80 Sn 20: 183: 280 [16] Pb: No: Sn20, UNS L54711. Used for coating radiator tubes for ...
