Abstract:
A heat transfer device comprising:a metal heat pipe unit defining a sealed inside cavity partially filled, in a partial vacuum, with a predetermined amount of working fluid capable of condensation and vaporization, said metal heat pipe unit comprising a heat absorbing section for absorbing heat in a high temperature region, and a heat releasing section for releasing heat in a low temperature region;wherein said metal heat pipe unit comprises a flexible platelike metal band which is made of a light metal, which extends along a longitudinal direction from a first longitudinal end to a second longitudinal end, and which is formed with a plurality of longitudinal holes extending along the longitudinal direction, said longitudinal holes being connected with one another to form said sealed inside cavity; andwherein said metal band is bent in such a sinuous manner that said metal band extends back and forth between the high temperature region and the low temperature region, and streams of a heat medium fluid flow substantially parallel to the side faces of the platelike metal band in the regions between the bends.
