Patent ID: 8650891

Claim:
A heat transfer arrangement for heat exchange between an inside of an electronic component housing and an ambient environment, said heat transfer arrangement comprising: a refrigerant circuit including an evaporator configured to be arranged inside said housing and to evaporate a self-circulating refrigerant, a condenser configured to be arranged outside said housing and to condense said refrigerant, a first conduit through which said refrigerant rises in gaseous form from said evaporator to said condenser, and a second conduit through which said refrigerant flows in liquid form from said condenser to said evaporator; and a reservoir that is connected to said refrigerant circuit, that is configured to be arranged inside said housing to be directly affected by the temperature therein, and that comprises a refrigerant chamber and a control chamber separated by a movable partition, wherein said refrigerant chamber is configured to hold said refrigerant in liquid form, and wherein said control chamber is configured to hold a control medium that expands in volume at higher temperatures and contracts in volume at lower temperatures to thereby adjust the size of said control chamber, adjust the respective amounts of said refrigerant in the refrigerant chamber and the refrigerant circuit, and control the temperature inside said housing.
