Abstract: A liquid cooling arrangement for peripheral board incorporates cooling plates on one side and resilient cushion on the opposite side and enclosing the peripheral board between the cooling plates and the cushion. The cushion exerts pressure on the backside of the peripheral board to ensure physical contact of the microchips and the cooling plates for good thermal conductance. Cooling hoses are connected to the cooling plates to circulate cooling liquid. An electrically insulating layer may be included between the backside of the peripheral board and the cushion. An extension frame may optionally be added onto the cooling frame to house the cooling houses and increase the variability of deployments.

Abstract: A topology of bi-directional multi-output multi-function converter is designed in a BBU. The concept of bi-directional multi-function multi-output converter may be designed for the application of BBUs in a data center to provide multiple control functionalizes, such as battery discharging, battery charging, fan speed control, pump control, as well as providing power for multiple components/devices simultaneously. The proposed converter has two characteristics: bi-direction and multi-output. With the function of bi-direction, the battery discharging and charging can be accomplished with the same converter. With the function of multi-output, different rails of output voltages or power can be applied to different components or devices in BBU, such as fan, pump, control IC chip, sensors and etc.
