The invention relates to a method for producing board
layers of freeze dryers by utilizing aluminum
alloy sections. The method is characterized by comprising the following steps of (1) rolling the aluminum
alloy sections; (2)
cutting the aluminum
alloy sections; (3)
machining cutting faces; (4) sealing
cutting faces at two ends; (5)
machining liquid inlet tubes and liquid outlet tubes on sealing faces (or two sides of the sections). The method has the remarkable advantages that an aluminum alloy material is high in
plasticity and can be machined into sections in any shape, the rigidity of the aluminum alloy material is higher than that of stainless steel, the
thermal conductivity of the aluminum alloy is excellent and is twice the
thermal conductivity of stainless steel, and cold and heat carried by
silicone oil in the board
layers can be released maximally through the excellent
thermal conductivity of the aluminum alloy, so the temperature uniformity of the board
layers is greatly improved.
