Abstract

An apparatus and method of controlling freezing in a liquid system is disclosed. The apparatus includes a heat exchanger having a initial zone characterized by a surface area to volume ratio. The apparatus also includes means for initiating freezing of a fluid from the initial zone to facilitate volume expansion during freezing in the direction of a final zone characterized by a final zone surface area to volume ratio. The apparatus can further include a plurality of zones located between the initial zone and the final zone, wherein a zone surface area to volume ratio is calculated for each zone. Preferably, the zone surface area to volume ratio of each zone progressively decreases from the initial zone in the direction of the final zone. Preferably, the final freezing zone has the lowest surface area to volume ratio and has sufficient elasticity to accommodate the volume expansion of all the fluid that has frozen from the initial zone.
