A thermal management system including a fluid flow mechanism. The fluid flow mechanism includes an electric machine. A conduit is formed through the electric machine allowing a heat transfer fluid to flow therethrough. The fluid flow mechanism includes a flow device configured to provide a first portion of the heat transfer fluid to a first heat exchange circuit and a second portion of heat transfer fluid to a second heat exchange circuit.

Two oil coolers (30, 32) are disposed so as to face each other in a front half of the inside of a heat exchanger chamber (26) defined in an upper revolving body (5), one oil cooler (31) is disposed in a rear half, and a space (E) formed between the oil coolers is used as work and passage spaces. Outside air as cooling air is allowed to pass through the respective oil coolers (30 to 32) by cooling fans (35), and cooling air that has passed through each of the two oil coolers (30, 32) disposed so as to face each other is made to mutually collide, and is discharged to the outside through a side outlet (38) of a front wall (26a) and a first upper outlet (39) of a ceiling (26e) of the heat exchanger chamber (26). Cooling air that has passed through the other one oil cooler (31) is made to collide with a left side wall (26c), and is discharged to the outside through a second upper outlet (40) of the ceiling (26e).

Provided is a cooling module, and more particularly, a cooling module configured to include a condenser, an intercooler, and at least one radiator, and discharge a heat exchange medium by changing a shape of peripheral components without configuring separate components such as a separate hose when the heat exchange medium inside a radiator disposed on an upper part of the intercooler is discharged.

A vehicle heating/cooling system has first and second fluid circulation loops for circulating engine coolant and automotive fluid. A first heat exchanger transfers heat from the coolant to air for the passenger compartment. A second heat exchanger transfers heat between the coolant and automotive fluid. A first valve has first and second inlets for receiving coolant from hot and cold coolant sources, and an outlet for discharging coolant to the second heat exchanger. A second valve has an inlet for receiving coolant from the first coolant source, and an outlet for discharging coolant to the first inlet of the first valve. The valve positions change with temperature of the coolant and the automotive fluid, providing preferential heating of the passenger compartment during cold start-up of the vehicle. The second heat exchanger and valves may be provided in a temperature control module.

The auxiliary circuit (14) includes an auxiliary radiator (15) and an auxiliary radiator bypass line (17) directing coolant past the auxiliary radiator (15) which are arranged in an upstream position of the further object (13, 28) in the auxiliary circuit (14) and a bypass valve (18) configured to control the coolant flow through the auxiliary radiator bypass line (17).

A fan arrangement for a cooling module in a vehicle. The vehicle (6) has a radiator fan (10) providing an air flow through a flow passage (5) and the cooling module in an intended flow direction. The cooling module includes a radiator (3) and at least one further cooler (1, 2) arranged in an upstream position of the radiator (3) with respect to the intended flow direction through the flow passage (5). The fan arrangement includes at least one additional electrically driven fan (4). The additional electrically driven fan (4) is arranged in the flow passage (5) in a position downstream of the radiator (3) and upstream of the radiator fan (10) with respect to the intended flow direction through the flow passage (5). The electrically driven fan (4) is configured to provide an air flow through a restricted portion (18) of the flow passage (5) and the cooling module during certain occasions when the operating conditions include the radiator fan not being in operation.

In the cooling system of construction equipment equipped with a plural number of heat exchangers including radiators, in providing a pressurized sealed type reservoir tank connected in parallel with radiators in the cooling water circulation system between the radiators and engine, said reservoir tank is arranged so as not to protrude upward exchanger other than radiator is set to be as the upper tier heat exchanger, and the radiator and oil cooler other than the above heat exchanger are arranged lower than the upper tier heat exchanger, and the horizontal width of inter-cooler thus arranged is made shorter than the horizontal width of radiator and oil cooler, and the tank space is formed laterally to the inter-cooler and thus pressurized sealed type reservoir tank is arranged for said tank space.

The disclosure relates to a method for operating a drive device of a motor vehicle, wherein the drive device has at least one heat-generating device and a cooling circuit for cooling the heat-generating device, and at least one first coolant cooler of the cooling circuit and at least one second coolant cooler of the cooling circuit are fluidically connected to the heat-generating device. It is thereby provided that the first coolant cooler and the second coolant cooler are fluidically connected in parallel to the heat-generating device, and that coolant arriving from the heat-generating device be divided by means of a control mechanism between the first coolant cooler and the second coolant cooler. The disclosure furthermore relates to a drive device of a motor vehicle.
