سردكننده (مبرد) (Condenser)

وسیله اى است تقریبا شامل دو لوله، كه یك لوله داخلى است و یك لوله خارجى كه این لوله خارجی لوله داخلى را در بر گرفته و بین جدار خارجى لوله داخلى و جدار داخلى لوله خارجى فاصله اى براى عبور مایع سرد كننده (معمولا آب سرد) وجود دارد.

روش كار به این صورت است كه آب سرد از یك طرف لوله خارجى وارد و از طرف دیگر خارج میشود و در این بین مقدارىاز حرارت بخار كه از یك طرف لوله داخلى وارد شده را میگیرد و بخار را سرد میكند و بخار سرد شده به صورت مایع از یكی از دهانه هاى لوله خارجى (بسته به حالت قرار داشتن سرد كننده) بیرون مى‌آید. از این وسیله معمولا در عمل تقطیر استفاده میشود.

 

سرد كننده بسته به نوع كارى كه لازم است انجام شود انواع مختلفى دارد كه در زیر شكل چند نمونه از آن آورده شده است.
