on the size and type of fin used and the heat transfer requirements of the particular system 0017 fig6 illustrates an exploded view of the cold plate body 14 with the fin 10 visible in a preferred embodiment of the present invention the assembly 12 is designed to be brazed so that the fin 10 becomes integral with and a part of the structural support of top and bottom plates 14 a and 14 b respectively the fin 10 is in intimate heat transfer contact with both plates 14 a and 14 b members 34 can be used to hold the plates 14 a and 14 b together maintaining the fin 10 in heat transfer contact with the plates 0018 fig7 is a cutaway view showing the liquid refrigerant distribution means 28 and the fin 10 sitting on bottom plate 14 b also shown is the transition from channels 30 to a tube type structure for allowing the refrigerant to exit the cold plate via outlet 24 of fig4 and 5 the cold plate with the fin as best illustrated in fig6 and 7 allows distribution of liquid refrigerant into the flow channels 30 to evenly distribute the liquid throughout the fin 10 configuration this prevents the formation of hot spots and pressure spikes during the cooling process introducing the liquid refrigerant to the fin 10 via channels 30 allows for efficient distribution of the fluid medium through the fin and allows the fin to be used to control the boiling separation.
