A reserve tank includes a vapor-liquid separator, an inlet portion, an outlet portion, and a protrusion. The vapor-liquid separator defines an inner space for separating a vapor phase and a liquid phase of a cooling water. The inlet portion defines a first opening through which the cooling water is supplied into the inner space and the outlet portion defines a second opening through which the cooling water is discharged from the inner space. The protrusion protrudes upward from a bottom surface of the vapor-liquid separator. An inner circumferential surface of the vapor-liquid separator and an outer circumferential surface of the protrusion are coaxially provided to define an annular passage in the inner space. The cooling water introduced from the first opening flows spirally in the annular passage.

The present disclosure provides a device for preventing the backward air flow of a reservoir tank for a vehicle, which may mount an backward air flow prevention tube extending to coolant on a connector of a reservoir tank to which a degassing hose is connected, and form an air collection slit hole communicating with an upper space of the reservoir tank in the upper portion of the tube to be openable or closable, thereby easily preventing the phenomenon in which the air within the reservoir tank flows back toward an engine, and easily collecting the air introduced from the engine side.

The reservoir tank includes: a tank body that stores cooling fluid; an inflow pipe for feeding the cooling fluid into the tank body; and a discharge pipe for discharging the cooling fluid from the tank body, in which the tank body has at least one tank chamber, a discharge port is provided in a bottom surface of the tank chamber or at a position adjacent to the bottom surface, the discharge pipe is connected to the discharge port, and a shield is disposed above the discharge port so as to cover the discharge port in a plan view.

A reserve tank includes a plurality of chambers, including a first chamber, a second chamber, and at least one intermediate chamber, a first inflow port connected to the first chamber, a first outflow port connected to the first chamber, a second inflow port connected to the second chamber, a second outflow port connected to the second chamber, and a plurality of partition walls separating the chambers. Each of the partition walls is provided with a corresponding one of a plurality of refrigerant flow ports. A specific refrigerant flow port includes a first through hole and a second through hole that pass through a specific partition wall and are separated from each other. The specific refrigerant flow port being a refrigerant flow port provided in the specific partition wall among the partition walls.

A deaerator includes gas nucleation media and a porous barrier. The deaerator may include growth media between the gas nucleation media and the porous barrier. The deaerator may be part of a system for removing gas from a fluid, where the system includes a tank with a fluid inlet and a fluid outlet and having a fluid flow path from the fluid inlet to the fluid outlet, and where the deaerator is in the fluid flow path. A method for removing gas from a fluid includes passing the fluid through the deaerator defining a fluid flow path.

A reservoir tank includes: a tank body in which cooling fluid is stored; an inflow pipe for sending the cooling fluid into the tank body; a discharge pipe for discharging the cooling fluid from the tank body; and a columnar member erected inside the tank body, in which the inflow pipe is connected to the tank body vertically below a liquid level of the cooling fluid stored inside the tank body, the columnar member extends in a substantially vertical direction when viewed along a center line of the inflow pipe, and a part of the columnar member is disposed on an extension line of the center line of the inflow pipe.

Provided is a reservoir tank which includes: a tank body that stores cooling fluid; an inflow pipe configured to feed the cooling fluid into the tank body; a discharge pipe configured to discharge the cooling fluid from the tank body; a columnar member erected inside the tank body; and a guide member provided inside the tank body, in which the inflow pipe is connected to the tank body at a position vertically below a liquid level of the cooling fluid stored inside the tank body, the guide member is configured to guide a flow of the cooling fluid flowing from the inflow pipe into the tank body, the flow being guided into a substantially horizontal direction toward the columnar member, the columnar member extends in a substantially vertical direction when viewed along the flow of the cooling fluid toward the columnar member, and a part of the columnar member is disposed on an extension line of the flow of the cooling fluid toward the columnar member.

A reserve tank includes a vapor-liquid separator, an inlet portion, an outlet portion, and a protrusion. The vapor-liquid separator defines an inner space for separating a vapor phase and a liquid phase of a cooling water. The inlet portion defines a first opening through which the cooling water is supplied into the inner space and the outlet portion defines a second opening through which the cooling water is discharged from the inner space. The protrusion protrudes upward from a bottom surface of the vapor-liquid separator. An inner circumferential surface of the vapor-liquid separator and an outer circumferential surface of the protrusion are coaxially provided to define an annular passage in the inner space. The cooling water introduced from the first opening flows spirally in the annular passage.

The invention relates to a vortex degassing device (1) for a fluid transfer circuit (F1, F2), in particular of a motor vehicle, this device (1) comprising: a first internal chamber (10) connected to a first inlet (11) for a fluid (F1) as well as to a first outlet (12) for a liquid fraction and to a second outlet (13) for a gaseous fraction, a second internal chamber (20) connected to a second inlet (21) for a fluid (F2) as well as to a third outlet (22) for a liquid fraction and to a fourth outlet (23) for a gaseous fraction,
the second chamber (20) being located above the first chamber (10) and the second outlet (13) extending through the second chamber (20) to the level of the fourth outlet (23).

The invention also relates to a fluid transfer circuit comprising at least one such device (1) as well as a method for using such a device (1).
