A Figure 1 is the image of one of the two peltiers. The proposed system requires two
peltiers. One peltier is fitted on a plaswood partition (i.e., PVC foam sheet) dividing
the two chambers housing the electronics and the blood warming components while the
other is fitted on one outer wall of the box. As previously mentioned, the sides of the
two peltiers that generate more heat are turned inside facing the blood shaker (see
Figure 5).
