## Abstract Transient heat conduction in a composite slab is investigated in the present work by using the orthogonal collocation method. The present numerical method is found to be quite efficient and highly stable even for the powerβtype temperature dependence of thermal conductivity which often

## Abstract This paper describes the influence of heat flow from highβtemperature refrigerant to lowβtemperature refrigerant through fins by thermal conduction. To estimate that influence, we applied a thermal network method that can consider refrigerant quality distribution in the heat exchanger.
A time-convolutive variational hypersingular integral formulation of transient heat conduction over a 2-D homogeneous domain is considered. The adopted discretization leads to a linear equation system, whose coe cient matrix is symmetric, and is generated by double integrations in space and time. As
