Abstract
A method is disclosed for uniformly cooling a cooling plate of a heat generating device. Sub-cooled refrigerant is flowed through a thermal expansion valve and then into the cooling plate as a two-phase refrigerant where the refrigerant is superheated. Any refrigerant remaining in a fluid state before reaching a sensing portion associated with the thermal expansion valve and exiting the cooling plate can be completely vaporized by a recuperative heat exchanger. The superheated refrigerant is then passed to the sensing portion so that the superheated refrigerant directly transfers heat to a fluid within the sensing portion and causes a pressure change that is communicated to a needle of the thermal expansion valve.
