Peltier电子冷却回路

Peltier电子冷却回路

LAMBDA兰达 Peltier电子冷却回路用于MINIFOR发酵生物反应器

该装置的冷却是基于通过Peltier cell的电流产生的电子冷却效果。 Peltier cell允许介质冷却，而不需要其他手段，如制冷压缩机或冷却水浴。 LAMBDA选用了根据“热管”原理工作的冷却回路，具有比铜的热传导高80倍(!)的优点，可用于各种级别的介质。 即使回路没有完全淹没在介质中，它也能工作。

LAMBDA兰达 Peltier冷却系统是极其紧凑和有利于当培养应在温度接近室温或室温下几度运行。 使用方便的隔离材料对容器进行隔离，可以实现较低的温度。 LAMBDA Peltier冷却回路消除了对冷冻循环浴的需要，这是昂贵的，并采取了许多宝贵的工作台表面。

LAMBDA兰达Peltier冷却回路，然而，不打算作为一个标准的冷冻冷却池的替代，在应用中，密集和快速冷却的介质是需要的。

Peltier冷却模组的冷却强度总是最大的。 通过增加MINIFOR发酵生物反应器的加热来补偿过度的冷却。 通过这种方式，始终可以实现精确的温度控制。

Peltier electronic cooling loop

LAMBDA Peltier electronic cooling loop for MINIFOR fermenter-bioreactor

The cooling with this device is based on the electronic cooling effect produced by the flow of electric current through a Peltier cell. The Peltier cell allows cooling of the medium without the necessity of other means like a refrigerating compressor or cooling water baths. LAMBDA has selected a cooling loop working according to the "heat pipe" principle, which has an advantage of having up to 80 times higher heat conduction compared to copper (!) and can be used with various levels of medium. It works even when the loop is not entirely submerged in the medium.

The LAMBDA Peltier cooling system is extremely compact and advantageous when cultures should be run at temperatures close to the room temperature or few degrees under the room temperature. Lower temperatures can be achieved by isolation of the vessel with convenient isolating material. The LAMBDA Peltier cooling loop eliminates the need of refrigerated circulating baths, which are expensive and take a lot of valuable bench surface.

The LAMBDA Peltier cooling loop is, however, not intended as a replacement of a standard refrigerated cooling bath, in applications, where an intensive and fast cooling of the medium is required.

The cooling intensity of the Peltier cooling module is always maximal. An excessive cooling is compensated by increased heating of the MINIFOR fermenter-bioreactor. In this way precise temperature control is always achieved.
