Problems solved by technology

In addition, there are too many places that need to be welded, which makes the thermal deformation of the board layer too large, which adds a lot of difficulty to the shaping. If the shaping is not good, it will directly affect the quality of the planer. It will cause a lot of trouble for water mills, abrasive belts, etc. Due to the weaknesses of stainless steel itself, such as its large specific weight (7.93kg/m3), poor rigidity, etc., the heavy weight of the board when it is hoisted causes the middle of the board to collapse, directly Affect the flatness of t

Example Embodiment

[0009] A production method for producing freeze-dryer slabs by using aluminum alloy profiles, characterized in that it consists of the following steps: (1) rolling the aluminum alloy profiles, (2) cutting the aluminum alloy profiles, (3) machining the cut surfaces, (4) Sealing of cutting surfaces at both ends, (5) Processing of liquid inlet and outlet pipes. The rolled aluminum alloy profile described in step (1) is a rolled sheet, and the cross section of the sheet is provided with a number of tube holes. The pipe hole is a rectangular hole. The step (2) of cutting the aluminum alloy profile is to transversely cut the rolled aluminum alloy sheet according to the length. The machining of the cut surface in the step (3) is to process the surface of the cut surface through the groove and the sealing surface. The processing of the through-groove is milling the interval between the tube holes of the aluminum alloy profile, the milling interval is that the same interval is only m...

Abstract

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.
