A transfer tube for a thermal transfer device can include at least one wall having an inner surface and an outer surface, where the inner surface forms a cavity, where the at least one wall further has a first end and a second end. The first end can be configured to couple to a terminus of a heat exchanger of the thermal transfer device. The second end can be configured to couple to a collector box of the thermal transfer device. At least a portion of the at least one wall can be disposed in a vestibule of the thermal transfer device. The cavity can be configured to simultaneously receive a first fluid that flows from the first end to the second end and a second fluid that flows from the second end to the first end.

In a generator including an engine, a rotating electric machine, and a cooling fan that rotates integrally with a rotor of the rotating electric machine, the cooling fan includes a plurality of fans disposed at an interval in an axial direction of the fan, and a cylindrical body that extends in the axial direction of the cooling fan with a cylindrical cross section in an inner peripheral space of an upstream fan and is disposed more on the upstream side than a downstream fan.

There is provided a generator system for generating power and heat. The system comprises an engine, an electrical power generator driven by the engine, a radiator for cooling engine coolant, a heater powered by the electrical power generator, and an airflow generation device driven by the engine. The heater has an airflow outlet and an airflow inlet. The airflow generation device has an air intake inlet and an air exhaust outlet. The system further comprises a first conduit directing airflow through the radiator into the air intake inlet of the airflow generation device. The system also includes a second conduit directing airflow from the air exhaust outlet of the airflow generation device to the airflow inlet of the heater. The airflow generation device may be a centrifugal fan that draws air through the radiator and pushes the air through the heater.

The invention relates to a cooling module (22) for a motor vehicle, preferably having an electric motor, comprising: —at least one heat exchanger (24, 26, 28), —at least one tangential turbomachine (30) capable of creating a flow of air in contact with said at least one heat exchanger (24, 26, 28), and —a fairing (40) for housing said at least one heat exchanger (24, 26, 28), wherein the fairing (40) comprises at least one indentation (34-1, 34-2, 36-1, 36-2, 38-1, 38-2) for retaining at least one heat exchanger.

An engine device includes an exhaust gas purification device above a cylinder head through a support pedestal. The support pedestal has a flat portion on which the exhaust gas purification device is mounted, and a plurality of legs which protrude downward form the flat portion and are fixed to the cylinder head. The flat portion and the leg portion are formed integrally. Portions between the legs are each formed in an arch-shape.
