A coolant de-aeration reservoir for a vehicle includes a shell, a plurality of compartments defined in the shell, and an inlet and an outlet extending from each of the compartments. The plurality of compartments are fluidly connected to each other.

A temperature control system for an engine. The system includes a thermal storage expansion tank defining a thermally insulated interior volume for storing engine coolant. The system further includes a pump that pumps engine coolant that has exited the thermal storage expansion tank back into the thermally insulated interior volume of the thermal storage expansion tank and forces air out of the thermal storage expansion tank to store coolant in the thermally insulated interior volume when the engine is off.

Power system radiators and power systems having radiators are disclosed. An example power system includes: an engine; a generator configured to generate electrical power from mechanical power provided by the engine; power conversion circuitry configured to convert the electrical power from the generator to welding-type power; and a housing enclosing the engine, the generator, and the power conversion circuitry; and a radiator assembly configured to cool the engine and comprising a heat exchanger oriented substantially horizontally when the power system is installed.

Methods and systems are provided for a cooling system. In one example, a system comprising a housing comprising a first chamber fluidly coupled to a first cooling circuit and a second chamber fluidly coupled to a second cooling circuit. A reservoir is arranged vertically above each of the first chamber and the second chamber within the housing. A transverse wall fluidly separates the reservoir from the first and second chambers and a dividing wall physically coupled to the transverse wall, separates the first and second chambers from one another. Each of the transverse wall, dividing wall, first chamber, and the second chamber are arranged vertically below a minimum fill line of the reservoir.

Systems and apparatuses include a de-aeration tank for an engine system. The de-aeration tank including a single internal volume defined by walls, a diesel exhaust fluid (DEF) doser port configured to communicate coolant with a DEF doser module, and engine coolant ports configured to communicate coolant with an engine coolant system.

An expansion tank for a vehicle cooling system and a vehicle cooling system. The expansion tank includes a tank body and a chamber provided inside the tank body, a liquid inlet and a liquid outlet are provided on the tank body, a diversion channel matched with a bottom of the tank body is provided inside the tank body, both ends of the diversion channel are respectively connected with the liquid inlet and the liquid outlet, a vent hole and a liquid refill hole are sequentially provided on a side of the diversion channel in a flow direction of a coolant liquid, and the vent hole and the liquid refill hole are both communicated with the chamber. The automatic separation of the air from the coolant liquid and the automatic refill of the coolant liquid can be realized by providing the diversion channel connecting the liquid inlet and the liquid outlet inside the tank body, and sequentially providing the vent hole and the liquid refill hole on the side of the diversion channel in the flow direction of the coolant liquid. Since the expansion tank is directly connected in series to the main cooling circuit of the motor, the cost input and arrangement space of pipelines, pipe clamps, and liquid-gas separators are reduced, and the weight of the cooling system is also reduced.

A deaeration tank includes a top wall, a bottom wall, a first side wall, a second side wall, a cavity, a fluid inlet, a fluid outlet, and a plurality of support members. The cavity is defined between the top wall, the bottom wall, the first side wall, and the second side wall. The cavity provides a path for fluid to flow between the fluid inlet and the fluid outlet. Each of the plurality of support members includes a first segment and a second segment. The first segment extends from the first side wall to the second side wall. The second segment extends perpendicularly from the first segment toward the bottom wall such that the support members are configured to direct fluid flowing within the cavity away from the top wall.

This disclosure pertains to a device for removing air from a coolant liquid of a coolant system. The device has a body with a swirl pot at one end and a manifold extending from the swirl pot to an opposed end of the body. The swirl pot has a fluid inlet for receiving coolant fluid of a first air concentration and a fluid outlet for discharging coolant fluid of a second concentration less than the first. The manifold has a first fluid pipe connected to a plurality of outlet pipes that extend transversely to the first fluid pipe and are spaced there along.

A coolant passage device 3 includes coolant intake pipes 11 and 12 that take in coolant from an engine, a delivery pipe 17 to a radiator communicating with the coolant intake pipes, and a delivery pipe 18 to the heater core branched from a central passage 16 connecting the coolant intake pipes with the delivery pipe to the radiator. A branch port 18a leading to the delivery pipe 18 to the heater core is opened in an upper portion in the central passage 16 in a state where the coolant passage device 3 is mounted to the engine, and the branch port 18a has a wall surface 21 surrounding the branch port and hanging down into the central passage 16. The wall surface 21 prevents bubbles contained in the coolant from entering the branch port 18a. And the coolant passage device consequently prevents coolant flow noise from occurring.

A liquid cooling system for cooling an electrical component, the liquid cooling system including a cooling circuit having at least one supply branch for supplying liquid coolant to an electrical component; and a de-aeration line to provide a connection between a high point and a junction point of the cooling circuit to bypass a part of the cooling circuit; wherein the pressure of the liquid coolant is lower in the junction point than in the high point during circulation of the liquid coolant in the liquid cooling system.
