Abstract
A heat transfer arrangement for heat exchange between an inside of an electronic component housing and an ambient environment. The heat transfer arrangement comprises a refrigerant circuit with an evaporator a condenser and conduits (). A refrigerant is arranged to self-circulate in a refrigerant flow in the refrigerant circuit. A flow control device () comprises a movable member () adapted to control the refrigerant flow. The movable member () affects a through flow area of one of the conduits (). The movable member () is adapted to move in response to a pressure change inside the refrigerant circuit by being affected from a first side by a refrigerant pressure inside the refrigerant circuit and from a second side by a spring force such that the refrigerant flow is changed.
