Abstract

A cooling regulation system (100) is described which includes: a valve (110) having an control device (120) configured for controlling an opening of an orifice (111) provided between a valve inlet (112) and a valve outlet (113) such that a flow of a coolant from the valve inlet to the valve outlet can be regulated; an evaporator (130) with a contact surface that is adapted to be thermally connected to a heat source (140, 141) such that a thermal load from the heat source is dissipated by the evaporator in an operating state of the cooling regulation system; and a regulation device (150) configured for regulating a position of the control device in order to regulate the flow of the coolant, wherein the regulation device is in thermal contact with the evaporator at a position at which a vapor quality [chi] of the coolant is [chi]<=[chi]cr, wherein [chi]cr is the critical vapor quality.

Description

technical field [0001] Embodiments of the present disclosure relate to cooling tuning systems and methods for cooling tuning. In particular, embodiments of the present disclosure relate to automatic cooling adjustment systems and methods for automatic cooling adjustments. More particularly, embodiments of the present disclosure relate to systems and methods suitable for automatically adjusting refrigerant flow in an evaporator of a cooling trim system. Background technique [0002] In contemporary high voltage direct current (HVDC) converters, insulated gate bipolar transistors (IGBTs) are typically cooled with forced water flow. However, as technology trends toward more compact designs, conventional thermal management may become insufficient. The main reason is that the overall heating power density increases because the heat-generating components (IGBTs) are more closely packed together. In order to overcome the thermal management problems that arise, cooling systems fo...
