Electronic board, has nozzles traversing projection plate by following projection direction, where projection direction of each nozzle forms specific angle with respect to direction perpendicular to base plate

摘要

#CMT# #/CMT# The board has a cold plate including a projection plate (42) between intake and evacuation holes (70, 72). Rectilinear nozzles (86-90) traverse the plate through and through by following a projection direction. Length of each nozzle along the direction is higher than/equal to width of the nozzle perpendicular to the direction for forming coolant e.g. water, jets (100-104) along the projection direction. The projection direction of each nozzle forms an angle (alpha) with respect to a direction perpendicular to a base plate (78), where the angle ranges between minus 30 to plus 30 degrees. #CMT#USE : #/CMT# Electronic board. #CMT#ADVANTAGE : #/CMT# The projection plate traversed by the nozzles can be fabricated in a simple manner when compared to the fabrication of an insert comprising channels directly emerging on the intake hole, thus simplifying the fabrication of the electronic board. The nozzles ensure better cooling of the electronic board. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of a projection plate utilized in a cold plate of an electronic board. alpha : Angle 42 : Projection plate 70 : Intake hole 72 : Evacuation hole 78 : Base plate 86-90 : Rectilinear nozzles 100-104 : Coolant jets.
