MODELING AND ANALYSIS OF MICROCHANNEL RADIATOR BONNET

M. Trivikram Sai Reddy, K. Gowthami.

Abstract
This paper aims at designing a microchannel surface bonnet radiator. The microchannel surface bonnet radiator
mechanism is a combination of high thermal conductivity radiator microchannels integrated along the automobile bonnet
surface which acts as a heat sink. Due to the forced convection effect produced as a result of the air interaction with the
surface of bonnet radiator due to the vehicle motion heat from the engine is transferred to the surroundings. The design of
extended bonnet surface radiator is carried out in Solidworks and the CFD analysis is carried out in ANSYS Fluent. A
numerical study is performed to investigate the thermohydraulic performance on different microchannel heat sinks (MCHS)
designs. MCHS with a circular cavity (MCHS-C), MCHS with a trapezoidal cavity (MCHS-T), MCHS with circular pin
(MCHS-CP), MCHS with angular slot circular pin (MCHS-ACP), and MCHS with triangular slot circular pin
(MCHS-TCP) are the proposed MCHS designs. Fluid flow and heat transfer characteristics are numerically evaluated for
Reynolds number (Re) ranging from 100 to 1200. The finite volume method (FVM) is adopted for solving the governing
equations, and the SIMPLE algorithm is utilized for the computations. The overall performance of the present design is
evaluated based on friction factor, Nusselt number and hydrothermal performance factor (PEC). The results indicate that of
the proposed designs MCHS-TCP has a better overall performance which gives a maximum PEC of 1.4980

Key words: Hydrothermal design enhancement, Microchannel heat sink, Cavity, Circular pin, Slot
