Embodiment

[0067] Next, the effect of the present invention will be described by comparing a preferred embodiment of the present invention with a comparative embodiment known in the prior art.

[0068] Adopt the 5415R type laboratory centrifuge of Eppendorf AG company, the refrigeration conduit 2, 12 of this centrifuge adopts spiral rectangular tube, the width of this spiral rectangular tube is 9.5mm, height is 5.5mm, and material thickness is 0.5mm . To this end, adopt the centrifuge container 1 (article number 5426123.101-00) of the series product of Eppendorf AG company, this centrifuge container diameter is 185mm, height is 70mm, and wall thickness is 1mm, and this centrifuge container is made of V2A-stainless steel (thermal Conductivity of about 15W / m*K), and set in the refrigeration pipe 2 through thermally conductive glue (thermal conductivity of about 15W / m*K), thereby constituting a comparative example. And in the embodiment of the present invention, adopt the series product st...

Abstract

The invention relates to a container and a device for indirect cooling of articles and a method for manufacturing the same. With the invention, significant indirect thermal transmission from outside of the container to inside of the container is implemented. Improvement on heat conduction and thermal transmission of a centrifuge container reduces power consumption of a cooling device in a process or cooling the centrifuge. With higher effective power of the centrifuge, larger number of revolutions can be implemented under a condition of same centrifugation article temperature, and / or power consumption of a refrigeration plant can be reduced under a condition of same centrifugation article temperature and same number of revolutions.

Description

technical field [0001] The invention relates to a container according to claim 1 , an apparatus according to claim 5 and a method for producing the container according to claim 7 . [0002] The invention relates in particular to laboratory centrifuges, that is to say centrifuges used eg in chemical, biological, biochemical or biotechnological laboratories. On the other hand, the invention can also be advantageously applied to centrifuges and mechanical stirring plants of large machine technology, as well as all plants requiring at least indirect cooling of the goods. In addition, the present invention is also used in pure refrigeration equipment, such as refrigerators and freezers, especially laboratory refrigerators and laboratory freezers that need to achieve deep cooling. In such a pure refrigeration appliance, the container forms an enclosing housing for the interior of the appliance, into which an object is placed. [0003] The present invention does not specifically re...
