A flexible pad with interconnecting internal passages for circulating a hot or cold liquid for treating a patient. The pad has an improved internal flow pattern that includes a set of partitions that separate the pad into a plurality of major fields that are connected in series to insure that liquid flows to all areas, i.e. fields, of the pad even when such pad is in folded condition. Within each field is a series of passages forming a crisscross waffle grid pattern for random liquid flow in many directions within each field to reduce the chance of blocking liquid circulation through the pad when it is in folded condition.
