Due to the rapid growth of power consumption of the chip, single chip power consumption increased to 300W ~ 500W, close to the limit of traditional cooling technology. And high power consumption chip into the mobile platform, equipment modularity, integration for the lightweight heat sink, miniaturization demand is also growing. Microchannel heat sinks have the advantages of high thermal conductivity, small size, small heat transfer group, etc., in high-performance electronic equipment, power electronic equipment, renewable energy systems and other applications have shown good thermal performance, is a highly efficient thermal management program. Microchannel heat sinks utilize the microfluidic principle to increase the ratio of surface area to volume, and are able to accelerate the heat transfer from the heat source to the coolant flowing through the microchannel.
Lori microchannel heat sink is mainly divided into microchannel liquid cooler and microchannel vapour chamber.
