Embodiment Construction

[0012] according to figure 1 , the vehicle 9 has an engine 10 which can be supplied with coolant from the coolant circuit 3 . The coolant absorbs undesirably lost heat in the power output of the engine 10 and is conveyed via the heat exchanger 2 , which functions as a radiator / cooler, for recirculation cooling. The heat exchanger 2 is designed here as a plate heat exchanger and is located vertically in front of the engine 10 in the direction of travel. In front of the heat exchanger 2 there is again a ventilation device 1 comprising two blowers 4 . Each blower 4 is configured such that the blower 7 blows the main air flow into a hollow ring 5 via a surrounding gap 6 on the inner side of the ring 5 in the direction of the heat exchanger 2 from The ring 5 flows out. This primary air flow is accelerated by the inner side of the ring 5 in the form of an airfoil profile in such a way that a multiplied secondary air flow is induced from the surroundings in the direction of the he...

Abstract

The vehicle (9) has a fan assembly (1) with a heat exchanger (2) that is integrated into a refrigerant circuit (3). The fan assembly generates airflow through the heat exchanger and includes a fan (4), which generates strong adjacent airflow using primary airflow from an annular element (5). The fan assembly is designed as a component of a radiator grill (8), and the annular element is formed with an inner-side rotating gap (6). The primary airflow is injected into the gap through a blower (7), and the annular element forms a frame of the radiator grill.

Description

technical field [0001] The invention relates to a vehicle comprising a ventilation device with a heat exchanger installed in a coolant circuit, wherein the ventilation device is capable of generating an air flow through the heat exchanger and has at least one fan capable of The flow creates a secondary air flow of multiple intensities. Background technique [0002] This type of ventilation device is disclosed by the prior art, such as German patent DE10239936A1. It forces air flow through the heat exchanger to improve the efficiency of the heat exchanger in heat exchange. Ventilation devices of this type are used in vehicle technology, for example, to ensure sufficient heat output from the coolant circuit via a heat exchanger when the vehicle is parked. German patent DE102006040429A1 describes a ventilation device with a plurality of fans of this type. A disadvantage worth mentioning, however, is that such a ventilation device requires a particularly large construction sp...
