Abstract: 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.

Abstract: A cooling circuit includes a first coolant passage in which a coolant flows, a second coolant passage in which the coolant flows, a thermostat, and an oil cooler configured to heat or cool oil. The thermostat interrupts a flow of the coolant flowing through the first coolant passage when a temperature of the coolant flowing into the thermostat is lower than a predetermined temperature, and allows the coolant to flow through the first coolant passage when the temperature of the coolant is at or above a predetermined temperature. The oil cooler includes a first coolant inflow port, a first coolant outflow port, a second coolant inflow port, and a second coolant outflow port. The oil cooler heats or cools the oil by heat exchange between the coolant flowing from the first coolant inflow port or/and the second coolant inflow port and the oil.
