AI Technical Summary
Existing heat transfer fluids have conductivity issues in electric vehicles, which may cause short circuits when batteries and power components are submerged. Furthermore, traditional synthesis methods are difficult to use on a large scale to produce methyl branched alkanes with excellent heat transfer properties.
Using linear α-olefins (LAO) as raw materials, a bifunctional catalyst containing solid acid components and hydrogenation components is used to react with hydrogen in a reactor to prepare a methyl branched alkane feed stream with suitable viscosity, pour point, and flash point for effective thermal management of electric vehicles.
Methyl branched alkanes with low electrical conductivity and high thermal transfer performance are provided, which are suitable for direct cooling of electric vehicle batteries and power electronic devices. They solve the conductivity and synthesis problems of traditional fluids and achieve more effective thermal management.
