Abstract
An apparatus and method are disclosed for ensuring adequate and uniform cooling for any heat-generating device that experiences large heat pulses by integrating parallel expansion devices and their control directly into each of a discrete cooling load or cold plate. One of the parallel expansion devices is an integrated cartridge thermostatic expansion valve (TXV) and the other is an electrically-actuated valve. The TXV is positioned such that a sensing element is located directly within an exit refrigerant stream, thereby improving time-response of the valve and eliminating the need for a capillary tube. The electrically-actuated valve provides a sudden burst of refrigerant while the TXV is responding to sudden heat pulses and operates at the command of the heat generating system or triggered by a temperature rise. The disclosed operational method leads to an order of magnitude reduction in settling time after a heat pulse.
