Abstract
A counterflow heat exchanger having a plurality of heat exchanger elements in a stacked, spaced-apart arrangement forming a plurality of inter-element passages. Each element has fluid passages formed between facing sections of a first plate and a second plate. A first-fluid passage has an outer passage circumscribing an inner passage in fluid communication with the outer passage. An inlet-port traversing passage in fluid communication with the outer passage, an outlet-port traversing passage in fluid communication with the inner passage and a second- fluid traversing passage circumscribed by the inner passage traverse the first and second plates. A first-fluid inlet header includes the inlet-port traversing passage of each element. A first-fluid outlet header includes the outlet-port traversing passage of each element. A second-fluid inlet passage in fluid communication with the plurality of inter-element passages includes the second-fluid traversing passage of each element.

a first-fluid passage formed between facing sections of the first plate and the second plate, the first-fluid passage comprising an outer passage circumscribing an inner passage in fluid communication with the outer passage;
an inlet-port traversing passage traversing the first and second plates, the inlet- port traversing passage in fluid communication with the outer passage;
an outlet-port traversing passage traversing the first and second plates, the outlet-port traversing passage in fluid communication with the inner passage; and a second-fluid traversing passage traversing the first and second plates, the second-fluid traversing passage circumscribed by the inner passage;
a first-fluid inlet header comprising the inlet-port traversing passage of each element; a first-fluid outlet header comprising the outlet-port traversing passage of each element;
and
a second-fluid inlet passage comprising the second-fluid traversing passage of each element, the second-fluid inlet passage in fluid communication with the plurality of inter- element passages.
2. The counterflow heat exchanger according to claim 1, wherein the plurality of heat exchanger elements is housed in an outer gas-tight wrapper comprising a separable two-piece shell.
3. The counterflow heat exchanger according to claim 2, wherein the outer gas-tight wrapper has a first-fluid inlet port in fluid communication with the first-fluid inlet header, a first-fluid outlet port in fluid communication with the first-fluid outlet heard, a second-fluid inlet port in fluid communication with the second-fluid inlet passage, an exhaust port in fluid communication with the inter-element passages and a condensate drain in fluid
