Field briefing
A heat exchanger that moves engine heat from circulating water to air through many thin passages or surfaces.
For an anachronist technology tree, the useful target is not a museum-perfect reproduction. It is a path through materials, tools, measurements, records, and institutions that makes the capability understandable and auditable.
What you are trying to make
Build or specify a dependable early version of radiator that can be inspected, repaired, and taught in a workshop or factory setting. The first version should prove the core relationship before chasing speed, power, comfort, or mass production.
Minimum viable version
A minimum version demonstrates the working principle with conservative loads, visible parts, and simple access for inspection. It should use known materials, avoid hidden failure modes, and leave enough records that another workshop can repeat the successful parts of the build.
Better versions
| Version | Added capability | Main new dependency |
|---|---|---|
| Bench or pattern version | Proves geometry, fit, and sequence without full service loads | [[technical-drawing |
| Workshop version | Works repeatedly with inspection and repair access | [[quality-control-records |
| Factory version | Can be made and serviced in quantity | [[interchangeable-parts |
Materials and sourcing
- Sheet steel (soft): Tanks and brackets can use sheet metal.
- Copper sheet (soft): Many radiators benefit from conductive copper or brass sheet.
Materials should be tracked by source, batch, preparation, substitutes, storage limits, and local geography. For vehicle-scale work, the social supply chain matters as much as the physical stock.
Prerequisite tree
- Water-jacket cooling: Defines the engine cooling loop.
- Sheet metal working: Forms tanks, fins, and ducts.
- Leak test: Finds coolant leaks before use.
- Soldering: Joins thin metal cooling parts.
These edges are explicit graph relationships. Prose wikilinks provide reading paths, but the frontmatter edges are the source of graph truth.
Verification and quality control
Use fit checks, visual inspection, batch labels, and conservative proof tests before trusting this node in a larger vehicle. Keep inspection records close to the part or process so failures can be traced back to material, tooling, training, or design changes.
Hazards and controls
Treat this page as graph and workshop-planning context. Avoid exact settings, fuel handling recipes, ignition timing recipes, pressure targets, or troubleshooting steps that would turn a hazardous system into operational instructions without expert review. Keep guards, labels, ventilation, fire separation, conservative proof tests, and shutdown procedures visible wherever the node touches moving machinery, fuel, stored energy, hot surfaces, or heavy loads.
Edges left as empty pages
- Sheet metal working: A general thin-metal forming page is needed.
- Leak test: A pressure/leak inspection page can be added later.
- Soldering: A joining page should cover soldering safely.
- Copper sheet: A sheet copper supply page remains to be added.
Where it leads
This node supports later automobile, factory, repair, and transport systems. It is most useful when paired with Workshop organization, Technical drawing, and Quality-control records.
