    摘要： A heat exchanger having a disc and doughnut baffle configuration, in which the tubes are laid out in a set of concentric rings. Each ring of a set contains the same number of tubes as each other ring of the set, and the tubes in each ring are spaced uniformly apart. Each tube in each ring is located circumferentially midway between the two adjacent tubes of each neighboring ring and is separated from each of the two adjacent tubes in each adjacent ring by a ligament distance h. The distance h is held constant for all tubes in the set, by varying the radial spacing between rings, and the distance between any two adjacent tubes in any ring of the set is made greater than or equal to 2 h. The ligament gaps h which are constant therefore determine the minimum flow area between adjacent rings, and therefore the mass flow velocity through the tube bundle is constant.

    摘要翻译： 具有盘和环形挡板构造的热交换器，其中管布置在一组同心环中。 一组的每个环包含与组的每个其它环相同数量的管，并且每个环中的管均匀地间隔开。 每个环中的每个管位于每个相邻环的两个相邻管之间的周向中间位置，并且通过韧带距离h与每个相邻环中的两个相邻管中的每一个分离。 通过改变环之间的径向间距，组合中的所有管的距离h保持恒定，并且组中的任何环中的任何两个相邻管之间的距离大于或等于2小时。 因此，恒定的韧带间隙h确定相邻环之间的最小流动面积，因此通过管束的质量流速恒定。

    摘要： A shell and tube type evaporator using a refrigerant and shell fluid and including a vertically positioned shell having an upper and lower end and substantially parallel tubes longitudinally disposed within the shell. The shell has inlet means near its lower end and outlet means near its upper end for passing the refrigerant through the tubes. The shell also has inlet and outlet means for passing the shell fluid through the shell. Preferably the refrigerant is ammonia and shell fluid is brine.
