A cooling system configured to remove heat from a chimney of a server cabinet. The system includes a first heat exchanger unit in the chimney of the server cabinet. The first heat exchanger has a fluid inlet for receiving a working fluid and a fluid outlet for discharging the working fluid. The first heat exchanger also has an upstream surface receiving waste heat generated by one or more servers and a downstream surface that discharges air cooled by the first heat exchanger. The upstream surface is generally perpendicular to the downstream surface.

A liquid-cooled plate and a heat dissipation device are disclosed. The liquid-cooled plate includes a single-phase channel and a two-phase channel. First fins are spaced apart in the single-phase channel and second fins are spaced apart in the two-phase channel. The first fins are configured to perform a heat exchange with a liquid-state coolant flowing through the single-phase channel to convert the liquid-state coolant after the heat exchange into a gas-liquid two-phase coolant, and the second fins are configured to perform a heat exchange with a gas-liquid two-phase coolant flowing through the two-phase channel to output a coolant after the heat exchange.

A battery chassis for immersion cooling includes one or more groups of battery cells, an inlet, a condenser, and one or more fluid connectors disposed on the top of the chassis. For example, an inlet is disposed on a bottom of the chassis to receive two-phase cooling fluid from an immersion container, and the two-phase cooling fluid is to extract heat from the one or more battery cells and to transform from a liquid form into a vapor. A condenser is disposed on a top of the chassis to condense the vapor contained within the chassis of the two-phase fluid back into the liquid form. One or more fluid connectors disposed on the top of the chassis to connect the condenser with external cooling fluid via a liquid line, and the battery chassis is to be at least partially submerged in the two-phase cooling fluid of the immersion container.

An immersion cooling system includes a tank, an isolation plate and a condenser. The tank includes a base plate and a sidewall connected with the base plate. The sidewall defines with the base plate a space configured to accommodate a cooling liquid. The isolation plate connects with the sidewall or the base plate and divides the space into a first subsidiary space and a second subsidiary space. The first subsidiary space is configured to accommodate electronic equipment which is immersed in the cooling liquid. The isolation plate and the base plate are separated from each other. The sidewall surrounds the condenser. A vertical projection of the condenser towards the base plate at least partially overlaps with the second subsidiary space. The electronic equipment evaporates a portion of the cooling liquid to form a vapor. The condenser is configured to condense the vapor into a liquid form.

An immersion cooling system includes a cooling tank, a housing and a valve. The coolant tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The housing covers a side of the cooling tank and thereby forms an enclosure. The valve has two ports, one of which communicates with the enclosure and the other communicates with a part of the cooling tank above the liquid coolant. The valve is configured to open in response to a gas pressure inside the cooling tank exceeding an upper limit.

An immersion cooling system includes a cooling tank and a filtration system. The cooling tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The filtration system includes a pipeline, a pump, a filter and a cooling device. The pipeline is in fluid communication with the cooling tank. The pump is disposed in the pipeline and is configured to drive the liquid coolant to flow through the pipeline. The filter is disposed in the pipeline and is configured to filter the liquid coolant. The cooling device is connected to the pipeline and is configured to cool the liquid coolant. The pipeline has an inlet connected to the cooling tank. The cooling device is located between the pump and the inlet of the pipeline.

An immersion cooling system includes a tank, a first condenser, an enclosure, a second condenser and a connecting pipe. The tank has a first space. The first space is configured to accommodate a cooling liquid for at least one electronic equipment to immerse therein. The first condenser is disposed inside the tank. The enclosure is disposed outside the tank. The enclosure forms a second space together with the tank. The second condenser is disposed in the second space. The connecting pipe includes a first end and a second end opposite to the first end. The first end is connected with the second condenser. The second end is communicated with the first space.

A fluid immersion cooling system includes a fluid tank that contains a layer of a dual-phase coolant fluid and one or more layers of single-phase coolant fluids. The dual-phase and single-phase coolant fluids are immiscible, with the dual-phase coolant fluid having a lower boiling point and higher density than a single-phase coolant fluid. A substrate of an electronic system is submerged in the tank such that high heat-generating components are immersed at least in the layer of the dual-phase coolant fluid. Heat from the components is dissipated to the dual-phase coolant fluid to generate vapor bubbles of the dual-phase coolant fluid. The vapor bubbles rise to a layer of a single-phase coolant fluid that is above the layer of the dual-phase coolant fluid. The vapor bubbles condense to droplets of the dual-phase coolant fluid. The droplets fall down into the layer of the dual-phase coolant fluid.

A cooling apparatus (100) cools a heat-generating instrument, such as an electronic instrument (2), installed in an installation apparatus. The cooling apparatus (100) includes a refrigerant flow path configured circularly by sequentially connecting a pump (1) that circulates a refrigerant in a liquid state, a cooler (3) that cools the heat-generating instrument with the refrigerant, and a radiator (5) that cools the refrigerant. The cooling apparatus (100) includes a discharge-side heat exchanger (7) provided in a flow path from the pump (1) to the cooler (3) in the refrigerant flow path, a suction-side heat exchanger (8) provided in a flow path from the radiator (5) to the pump (1) in the refrigerant flow path, and a Peltier device (9) that is provided between the discharge-side heat exchanger (7) and the suction-side heat exchanger (8), and transfers heat from the refrigerant flowing through the suction-side heat exchanger (8) to the refrigerant flowing through the discharge-side heat exchanger (7).
