Flow distributor for heat transfer plate

Abstract

A flow distributor for a heat transfer device having a plurality of channels includes a sheath defining a plurality of distributor holes, each distributor hole configured to be in fluid communication with a respective channel inlet of each channel of the heat transfer device and an insert defining a plurality of fluid channels therein and a fluid inlet, each fluid channel in fluid communication with the fluid inlet. The insert is disposed within the sheath to seal the fluid channels with each fluid channel in fluid communication with a respective one of the distribution holes. The fluid inlet includes an inner inlet and an outer inlet radially outward from the inner inlet for mixing a fluid flow in the fluid inlet for evenly distributing fluid flow (e.g., a two phase flow) into the fluid channels of the insert and into each channel of the heat transfer device.

Description

BACKGROUND[0001]1. Field[0002]The present disclosure relates to heat transfer systems, and more particularly to heat transferring structures and plates.[0003]2. Description of Related Art[0004]Electrical components in circuitry (e.g., aircraft or spacecraft circuits) require sufficient heat transfer away from the components and / or the system in order to continue to function. Many mechanisms have been used to accomplish such a task, e.g., fans, heat transfer plates, actively cooled devices such as tubes or plates including tubes therein for passing coolant over a hot surface. While circuitry continues to shrink in size, developing heat transfer devices sufficient to move heat away from the components is becoming increasingly difficult.[0005]Certain heat transfer devices include multiple layers of passages for refrigerant to pass therethrough, all connected to a single inlet. Due to co-existence of multiple states (e.g., liquid and gas) of the refrigerant, the fluid enters into the di...
