Abstract

A high-velocity low-pressure cooling system (100), especially suited for data center applications, includes an air coolant loop (102), a non-air coolant loop (104) and a cooler unit (126) for heat transfer between the loops (102 and 104). The air loop (102) is used to chill ambient air that is blown across heat transfer surfaces of equipment mounted in data center racks (110). In this manner, effective cooling is provided using a coolant that is benign in data center environments.

First claim

What is claimed:

1. An apparatus for use in a closed-loop, air-based coolant circuit, comprising:
a conduit assembly comprising:
a delivery passageway for delivery of coolant air from a cooling unit to a heat exchange site where the coolant air is warmed due to heat exchange; and
a return flow passageway for delivery of the coolant air from the heat exchange site to the cooling unit; and

a reed valve subassembly configured to obstruct air flow associated with the delivery passageway when a first conduit section of the delivery passageway is disconnected from a second conduit section of the delivery passageway, wherein:
the first conduit section comprises the reed valve subassembly; and
each valve finger is operatively associated with a respective lever arm extending from a portion of an outer surface of the first conduit section.

2. The apparatus of claim 1 , wherein:
the reed valve subassembly is biased toward the closed configuration wherein each lever arm extends outward from the portion of the outer surface of the first conduit section.

3. The apparatus of claim 2 , wherein:
the second conduit section comprises a flanged section dimensioned to extend over the portion of the outer surface of the first conduit section such that each lever arm is depressed by the flanged section when the first conduit section and second conduit section are connected to open the reed valve.
