Heat transfer rate in plate type heat exchanger was quite less. This problem could be solved by using graphene composite inks. Graphene ink has been prepared by using Graphite nano powder, epoxy resin, sodium silicate mixture of high thermal conductivity by stirring. The graphene composite ink was then coated on cast iron disc and allowed to dry. When composite ink used as a thermal interface on plate type heat exchanger increased the heat transfer efficiency.Graphene has received significant attention due to unique electrical, optical and thermal transport properties. The extremely high thermal conductivity and electrical conductivity may make graphite be used as fillers in porous ceramic matrix to provide enhanced thermal properties and replace metal or graphite parts in thermal management systems. The coated disc has been kept on magnetic stirrer with an constant temperature and then raise in temperature was noted for a period of time say five minutes and then heated composite ink coated cast iron was taken for the testing methods using infrared thermometer (IR Thermometer) to find the thermal conductivity of the different composition of graphene ink. Thus from the testing, thermal conductivity of the material has been found. To inspect thermal properties the model of plate type heat exchanger were designed using software (solid works) to simulate thermal conduction for the different types of graphene composite inks. The simulation result reveals the best composition and displays more efficient heat transfer rate as compared to others. As a result this work proves that the most improved and easiest way of heat transfer rate using the graphene composite ink benefiting practical application such as the plate type heat exchanger ,heat sinks etc.
