▎ 摘　　要

The industrial growth of any country depends on energy source availability and utilization of energy for various applications. The heat exchanger is a heat transfer device which is most widely used in various applications for effective heat transfer between cold and hot fluids. Any improvement in heat transfer results in enhancement in overall performance of the device. Hence various techniques are used to improve the heat transfer. The solid particles which have higher thermal conductivity and can be used to improve the heat transfer between hot and cold fluids. The thermal conductivity of graphene-based nanoparticle is high, and it has low erosion, corro-sion, higher stability, etc. Hence graphene-based nanoparticle is chosen in various heat transfer applications. The use of graphene-based nanoparticles increases the heat transfer and hence it can reduce the size of the heat transfer equipment. This paper critically reviews various applications of graphene in different types of heat exchangers, electronic devices challenges and opportunities, by highlighting the advantages of using graphene.
