The utility model discloses a movable laboratory sample subpackaging and low temperature storage device belongs to laboratory low temperature storage equipment technical field, and the originality is adopted
semiconductor refrigeration technology, according to the downward propagation of cold source and its single side
refrigeration, the other side heating characteristic,
semiconductor refrigeration piece matrix sets up in the top of freezer, and the heating surface is close to the upper end surface of freezer, and through the upper end surface carries out heat dissipation, and the cold source is contacted with the freezing storehouse downward, in order to further promote the
cooling effect, the circulation wind structure of the application increases, and the contact area of cold source and freezing storehouse is increased, and the four end surfaces of freezing storehouse spread the
cold air inwards, and the
cooling effect is remarkable, in addition, the application is specially set up
screw pump subpackaging mechanism and
gear pump subpackaging mechanism, and the
screw pump subpackaging mechanism is good at subpackaging high
viscosity sample, and the
gear pump subpackaging mechanism is good at subpackaging low
viscosity sample, plus the setting of walking wheel, can realize the cross -region movement cooperation demand, different
viscosity sample quick subpackaging demand and high -precision subpackaging demand simultaneously.
