A critical review of the straight and wavy microchannel heat sink and the application in lithium-ion battery thermal management

As demand for high-performance heat transfer increases, interest in microchannel heat sinks as a viable solution for heat flux removal in thermal devices has grown significantly. Microchannel heat sinks with straight and wavy designs are the two main varieties that have been the focus of extensive research in this field. The current paper provides beneficial information regarding the different designs and methods for heat enhancement and overall thermal performance in straight and wavy microchannel heat sinks. Besides using nanofluids, modified designs improve heat transfer performance due to incorporating secondary flow. Moreover, utilizing microchannels as indirect cooling methods in lithium-ion battery thermal management is discussed in this review. This study discusses current issues and future research directions. © 2022 The Authors
