A heat pipe is formed of two elongated tubular members each having an open end and a closed end and joined at their open ends in gas-tight relationship by means of an annular collar. The annular collar is adapted at one end to fit over the open end of one of the elongated tubular members and at its other end to fit over the open end of other of the elongated tubular members, with the ends of the annular collar being sealably secured, such as by welding, bonding, threading or otherwise, to their respective tubular members thereby providing a gas-tight enclosure within the interconnected tubular which constitutes the working chamber of the heat pipe. Advantageously, the two elongated tubular members may be formed of dissimilar materials. For example, one tubular member may be formed of a more expensive material having a relatively high corrosion resistance and the other tubular member may be formed of a less expensive material having a relatively low corrosion resistance.
