A heat exchanger module with a first block of a first heat exchanger, further with a second block of a second heat exchanger, and further with an expansion valve, wherein the first block, the second block and the expansion valve are designed as an interconnected module.

A cooling device having a vaporizer for vaporizing a working liquid, wherein the working liquid is held on a vaporizer bottom; a compressor for compressing a vaporized working liquid, wherein the compressor is configured to convey the vaporized working liquid from the bottom to the top in a setup direction; a liquefier having an upper wall configured such that the vaporized and compressed working liquid is condensable at the upper wall and drips down from top to bottom; and an intermediate bottom configured to collect a dripped-down working liquid, wherein the intermediate bottom comprises at least one opening through which the dripped-down working liquid may reach the vaporizer bottom.

In a heat pump cycle device, a flow passage switching portion includes a flow passage switching valve body configured to open and close a cooling side flow passage. A refrigerant circulation circuit includes a low-pressure flow passage through which a low-pressure refrigerant decompressed by a first decompressor flows toward a compressor in a heating mode, and a pre-evaporator flow passage provided between the flow passage switching valve body and a refrigerant inlet of an evaporator. The flow passage switching portion causes a pre-evaporator flow passage to communicate with the low-pressure flow passage while bypassing the evaporator when a refrigerant pressure in the low-pressure flow passage is lower than a refrigerant pressure in the pre-evaporator flow passage, in the heating mode.

A cooling device includes a number of cooling tubes arranged in parallel such that a first cooling fluid and a second cooling fluid can flow in the cooling tubes. A tank communicates with the cooling tubes to allow the first cooling fluid or the second cooling fluid to flow through the cooling tubes. A diaphragm is located inside the tank to separate the tank into a first space allowing the first cooling fluid to flow therein and a second space allowing the second cooling fluid to flow therein. The diaphragm is coupled to the tank to be rectilinearly movable in a direction of an arrangement of the plurality of cooling tubes.

A condenser for a heating, ventilation, air conditioning and refrigeration system includes a condenser shell, a refrigerant inlet located at the condenser shell, and a condenser drain located at the condenser shell. A condenser tube bundle is located in the condenser shell such that a refrigerant flow entering the condenser via the refrigerant inlet passes over the condenser tube bundle before exiting the condenser at the condenser drain. Two or more condenser ballast volumes are located in the condenser shell between the tube bundle and the condenser drain. The two or more condenser ballast volumes are spaced apart to define a channel therebetween. A condenser ballast volume of the two or more condenser ballast volumes has a horizontal top surface.

The present invention relates to a condenser, and more particularly, to a condenser in which a configuration and an assembly are simplified by forming a condensation region in which plates are stacked and refrigerant is condensed and a super cooling region in which the refrigerant is supercooled, arranging a connection plate to which a gas-liquid separator is coupled between the condensation region and the super cooling region, and forming the refrigerant and cooling water to flow between the condensation region and the super cooling region, in a water cooling condenser.

The invention relates to a plug-in device (90) for a cylinder of a condenser, this plug-in device comprising: a plug (100) designed to plug, preferably removably, an opening of the cylinder, a functional component (200; 300) designed to interact with a refrigerant fluid in the cylinder, this functional component being designed to be mounted, removably or non-removably, on the plug with the possibility of rotating with respect to this plug.

A heat exchanger includes a liquid reservoir configured to separate a gas-liquid two-phase refrigerant flowing out of an upstream heat exchanging portion into a gas-phase refrigerant and a liquid-phase refrigerant, and a refrigerant adjustment portion configured to adjust an outflow state and an outflow destination of the refrigerant flowing out of a downstream heat exchanging portion or the liquid reservoir. The liquid reservoir includes a liquid reserving portion configured to store the liquid-phase refrigerant and a gas reserving portion configured to store the gas-phase refrigerant. The refrigerant adjustment portion faces the liquid reserving portion across the gas reserving portion.

A manifold includes: a branch pipe including an inflow port and a plurality of outflow ports; and a partition wall that partitions an inside of the branch pipe into a side of the inflow port and a side of the plurality of outflow ports and includes: a plurality of through-holes that have a total opening area greater than an opening area of the inflow port; and a plurality of first facing portions that face the respective outflow ports.

A heat exchanging module (1) comprising a heat exchanger (2) and a bottle (6), the bottle (6) being attached to the heat exchanger (2) at one first longitudinal end (63) of the bottle (6), said heat exchanging module (1) comprising at least one attachment mean (10) located at a second longitudinal end (64) of the bottle (6), said attachment mean (10) restricting at least one axial movement of the bottle (6) along a longitudinal dimension (5) of said bottle (6).
