§1What this business is
A copper pipe is fitted with a wick (often sintered metal powder), evacuated, filled with a small amount of working fluid, heat-treated and sealed. Heat moves from the hot end to the cold end by evaporation and condensation. Buyers are makers of electronics cooling parts, HVAC and refrigeration equipment and heat exchangers.
Capacity: 96 heat pipes a day on an 8-hour shift; year 1 at 40%.
§2Is it right for you?
Who it is for
An engineer or technician with links to HVAC, refrigeration or electronics makers.
Who it is not for
Someone without technical skills or OEM contacts.
Advantages
- Growing use in electronics cooling and HVAC
- Small space (1,200 sq ft)
- Technical product with fewer small competitors
- Can supply OEMs on contract
Drawbacks
- Needs precise vacuum and sealing — defects are hard to see
