Disclosed herein is a heat exchanger apparatus comprising a heat exchanger tube having an inlet valve and an outlet valve. When the valves are open, the refrigerant can flow through the heat exchanger tube, and when the valves are closed, refrigerant can be stored in the heat exchanger tube, thereby reducing the effective heat exchange surface area of the heat exchanger apparatus.

A cold plate device and method for cooling electronic systems is provided including a generally flat thermally conductive body having a cooling channel within the thermally conductive body. A first cooling fluid travels through the cooling channel to remove heat from the conductive body. A vapor compression cycle system is coupled to the thermally conductive body such that the first cooling fluid removes heat from a second cooling fluid in a portion of the vapor compression cycle system.

A refrigeration circuit includes: a gas-liquid separator into which a gas-liquid two-phase refrigerant flowed out from a condenser flows, the gas-liquid separator being configured to separate the gas-liquid two-phase refrigerant into a vapor phase refrigerant and a liquid phase refrigerant; and a plate heat exchanger including a first heat exchanging part and a second heat exchanging part, the first heat exchanging part being a part where the vapor phase refrigerant flowed out from the gas-liquid separator and the liquid phase refrigerant flowed out from the gas-liquid separator exchange heat, the second heat exchanging part being a part where the vapor phase refrigerant flowed out from the first heat exchanging part and a returning refrigerant flowed out from an evaporator exchange heat.

Disclosed are a condenser module and a thermal management system including the same. The condenser module includes a heat exchange device including a first inlet/outlet and a second inlet/outlet having a refrigerant flowing thereinto or discharged therefrom and a flow path formed therein through which the refrigerant flows between the first inlet/outlet and the second inlet/outlet, and a flow-path switching valve connected to each of the first inlet/outlet and the second inlet/outlet, the flow-path switching valve switchable between a first operation mode, in which the refrigerant flows into the first inlet/outlet and the refrigerant is discharged from the second inlet/outlet, and a second operation mode, in which the refrigerant flows into the second inlet/outlet and the refrigerant is discharged from the first inlet/outlet. The flow path formed in the heat exchange device has different positions in a direction of gravity between the first inlet/outlet and the second inlet/outlet.

A refrigeration appliance has a refrigeration appliance component and a cleaning device for cleaning the component. The cleaning device includes a cleaning element, an actuating element, and a connection element. The cleaning element is connected to the actuating element by the connection element. The refrigeration appliance has a cavity which extends from the front side of the refrigeration appliance to the back side of the refrigeration appliance, and in which the connection element is accommodated. The cleaning element is moveable across a surface of the refrigeration appliance component upon actuation of the actuating element in order to remove dirt deposits from the surface of the refrigeration appliance component.
