摘要： PURPOSE:To fix efficiently plural heat collecting fins to branch pipe in assembling a solar heat collector by fitting the plural fins to the plural branch pipes, attaching the branch pipes to a base pipe and expanding the branch pipes by the internal pressure from the end of the base pipe. CONSTITUTION:Many heat collecting fins 1 are fitted onto many branch pipes 2. The pipes 2 are assembled to a base pipe 3 by welding or other means. The end of the pipe 3 is sealed and an internal pressure is exerted on the pipe 3. The pipes 2 are expanded to fix the fins 1 arranged in the specified position. The many fins 1 are thus fixed and attached simultaneously by the extremely simple operation and the working efficiency is considerably improved.
