IPC: F28F21/02
Filed: 1993-06-24
Abstract: PURPOSE:To obtain a heat-conductive pipe having a desired strength by a method wherein carbon fibers having a specified diameter are arranged in a mesh pattern, bonded together by a synthetic resin and formed into a tubular shape. CONSTITUTION:Carbon fibers 1 having a diameter of 3-15mum are arranged in a mesh pattern, bonded together by a synthetic resin and formed into a tubular shape. To bond the carbon fibers by the synthetic resin, the carbon fibers 1 are immersed in the synthetic resin, then taken out and wound on a core, or the synthetic resin is sprayed to the carbon fibers after or while the carbon fibers are wound on the core. Fibers to be used can be carbon fibers alone but some amount of metallic fine wire can be mingled. Thereby, an effective high-strength can be exhibited by aligning the molecule direction by stretching in production step. In addition, a heat-conductive pipe with a rather thin wall thickness and a desired strength can be obtained.
