Automatic in situ coolant flow control in LFT heat exchanger

摘要

In association with a liquid flow through a heat exchanger situated to remove heat from electronic devices, a coolant flow control apparatus is provided. The coolant flow control apparatus comprises a first input channel for carrying liquid coolant to a first input of the heat exchanger; a flow control device positioned along a flow path that includes the first input channel, the flow control device, in response to a temperature of coolant proximate to the flow control device, is operable to enable or to prevent coolant flow along the first input channel into the heat exchanger; a second input channel for continuously carrying liquid coolant to a second input of the heat exchanger, during both times when the flow control device is enabling and is preventing the coolant flow along the first input channel into the heat exchanger; and an output channel for carrying coolant away from the heat exchanger.

1. A coolant flow control apparatus comprising:
a first input channel for carrying liquid coolant to a first input of an electronic device heat exchanger; a flow control device selectively positioned along a flow path that includes the first input channel, wherein the flow control device, responsive to a temperature of coolant proximate to the flow control device, is operable to enable or to prevent, selectively, coolant flow along the first input channel into the electronic device heat exchanger; a second input channel for continuously carrying liquid coolant to a second input of the electronic device heat exchanger, during both times when the flow control device is enabling and is preventing said coolant flow along the first input channel into the electronic device heat exchanger; and at least one output channel for carrying coolant away from the electronic device heat exchanger, wherein the at least one output channel is configured to be, selectively in fluid communication with the first input channel, and continuously in fluid communication with the second input channel, through the electronic device heat exchanger.
