In injection molds and compression molds, slender cooling channels or heating pipes are used to control the temperature over the cavity surfaces of the molds. The optimum design of layout and size of such slender channels is important for high-quality production and reduction of the forming cycle time of products. In this paper, a boundary element approach for design sensitivity analysis of cooling or heating of such molds is presented. The boundary integral equation for steady-state heat conduction problems implemented with a special type of pipe elements is first differentiated with respect to an arbitrary design parameter, and a boundary integral equation relating the temperatures and heat fluxes to their sensitivity coefficients is derived. The effectiveness of the system developed based on the above formulation is illustrated through some numerical test examples.
