The heat generated by a Slab Lasers can exceed
1,000 watts but the area available for cooling is too small. This
results in localization of heat flux which makes heat dissipation a
challenge in slab lasers. The Heat transfer coefficient can
increase up to a very high range, which can’t be efficiently
achieved by the conventional water cooling. Micro-channel
coolers address this problem competently. These channels
contain liquid, which transfers heat to the sink with high
efficiency.The objective of this paper is to design the microchannel coolers that will be efficiently capable of removing the
heat from the slab laser without causing any thermal distortion in
the laser. The dimension of the slab is given as follows:-Length(l)
=50mm, Width(w) =8mm and thickness(t)=2mm.
