LNG (liquefied natural gas) and LIN (liquid nitrogen) in transit refrigeration heat exchange system

摘要

A heat exchanger includes a housing disposed in a first atmosphere and having an upstream end, a downstream end and a chamber within the housing; a metallic block disposed in the chamber and having a passageway therethrough and through which a cryogen can flow; and a heat pipe assembly in contact with the metallic block and extending to a second atmosphere which is separate from the first atmosphere for providing heat transfer at the second atmosphere.

1. A heat exchanger, comprising:
a housing disposed in a first atmosphere and having an upstream end, a downstream end and a chamber within the housing; a first metallic block disposed in the chamber the first metallic block comprising:
a first passageway extending therethrough and through which a first cryogen can flow, the first cryogen comprising a cryogenic substance selected from the group consisting of liquid nitrogen and liquid natural gas, and the first passageway comprising a first inlet port at the upstream end of the housing and a first outlet port at the downstream end of the housing; a first inlet pipe in communication with the first inlet port for providing the first cryogen to the first passageway; a first outlet pipe in communication with the first outlet port for exhausting cryogenic vapor from the first passageway to power an engine; and a first heat pipe assembly in contact with the first metallic block and extending to a second atmosphere which is separate from the first atmosphere for providing heat transfer at the second atmosphere.
