AbstractExpansion jointed corrugated elliptic heat pipe consists of thin-wall expansion jointed corrugated base pipes, sleeved fins and thick-wall sleeve. It has the features including elliptic working cross section of heat pipe with small outer flow resistance and great heat exchange coefficient; close contact between the expansion jointed thin-wall base pipe and the fins resulting in small pipe wall contact heat resistance and small heat conducting resistance; and the corrugation in the base pipes formed while expansion joint capable of reinforcing the working medium inside the pipe and reducing hot stress. The thin-wall base pipe may be manufactured with stainless steel and similar material for anticorrosive capacity and low cost.
