    摘要: The present invention is a multi-pass heat exchanger for use with sterile liquids. The multi-pass heat exchanger includes a tube body and a bonnet, the bonnet being connected to a tubesheet of the tube body. Arranged in the bonnet and dividing the bonnet into at least inlet and outlet chambers is at least one web for directing the liquid conveyed into the bonnet. The web is connected to the bonnet. A gap is provided between the web and the tubesheet, allowing fluid exchange between the bonnet chambers. In this way, a leakage flow, which flushes the gap clear to prevent any type of bacterial deposit or contamination, can flow between the chambers formed by the web. Because the risk of contamination is eliminated, the heat exchanger can be used for the cooling of liquid present in the ultra-pure state, in particular of ultra-pure water.
