Spot-Cooling with a Cryogenic Pump

With the increase of performance demands, the nonuniformity of on-chip power dissipation becomes greater, causing localized high heat flux hot spots that can degrade the processor performance and reliability. In this paper, a three-dimensional model of the copper microchannel heat sink, with hot spot heating and background heating on the back, was developed and used for numerical simulation to predict the hot spot cooling performance. The hot spot is cooled by localized cross channels. The pressure drop, thermal resistance and effects of hot spot heat flux and fluid flow velocity on the cooling of on-chip hot spots, are investigated in detail.

Fueling Station

More and more LCNG fueling stations being built in several cities of China, it brings some problems on safety ensuring, rapidly constructing, cost saving, stable controlling, convenient moving. According to the requirements of the technological process, a kind of skid-mounted LCNG (Liquefied Compressed Natural Gas-engines) fueling station is designed. The station integrates those main equipments, such as LNG cryogenic pump, LNG vaporizer, and electrical control cabinet. Using a touch screen with a PLC in the electrical control cabinet, and it is an easy and less cost way to discharging the field controlling. The control system structure and the software are also designed for stable controlling. Compared to traditional CNG fueling station, it can be less land consumption, low construction cost, easily moving, and the skid-mounted LCNG fueling station has very wide application foreground.
