Peltier電子冷卻回路

LAMBDA蘭達(dá) Peltier電子冷卻回路用于MINIFOR發(fā)酵生物反應(yīng)器

該裝置的冷卻是基于通過Peltier cell的電流產(chǎn)生的電子冷卻效果。 Peltier cell允許介質(zhì)冷卻，而不需要其他手段，如制冷壓縮機(jī)或冷卻水浴。 LAMBDA選用了根據(jù)“熱管”原理工作的冷卻回路，具有比銅的熱傳導(dǎo)高80倍(!)的優(yōu)點(diǎn)，可用于各種級(jí)別的介質(zhì)。 即使回路沒有完全淹沒在介質(zhì)中，它也能工作。

LAMBDA蘭達(dá) Peltier冷卻系統(tǒng)是極其緊湊和有利于當(dāng)培養(yǎng)應(yīng)在溫度接近室溫或室溫下幾度運(yùn)行。 使用方便的隔離材料對(duì)容器進(jìn)行隔離，可以實(shí)現(xiàn)較低的溫度。 LAMBDA Peltier冷卻回路消除了對(duì)冷凍循環(huán)浴的需要，這是昂貴的，并采取了許多寶貴的工作臺(tái)表面。

LAMBDA蘭達(dá)Peltier冷卻回路，然而，不打算作為一個(gè)標(biāo)準(zhǔn)的冷凍冷卻池的替代，在應(yīng)用中，密集和快速冷卻的介質(zhì)是需要的。

Peltier冷卻模組的冷卻強(qiáng)度總是最大的。 通過增加MINIFOR發(fā)酵生物反應(yīng)器的加熱來補(bǔ)償過度的冷卻。 通過這種方式，始終可以實(shí)現(xiàn)精確的溫度控制。

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.
