Definitions

  • the invention relates to an air duct system for a passenger cell and a drive cell with a battery or fuel cell of a motor vehicle with a fresh air mass flow introduced into the passenger cell, a cooling mass flow cooling the drive cell and an exhaust air mass flow discharged into the atmosphere.
  • a generic cooling system for a fuel line system is already known from DE 196 29 084 C2.
  • a gaseous cooling medium flows through the optionally secondary cooling system.
  • the fuel cell system is arranged in such a way that the secondary cooling medium is introduced entirely or partially into the cooling system of the fuel cell system due to the dynamic pressure of the airstream.
  • the invention is based on the object of designing an air duct system for a drive cell in such a way that the cooling of the drive cell can be regulated more precisely and is energy-saving.
  • the object is achieved in that a ventilation device or an air conditioning system of the vehicle at least partially circulates the air inside a passenger compartment in a recirculation mode, the substantial proportion of the fresh air mass flow fed into the passenger compartment after flowing through the passenger compartment as cooling mass flow is supplied to the drive cell and the cooling mass flow is discharged into the atmosphere immediately after cooling the drive cell.
  • the cooled fresh or circulating air mass flow is used to cool the drive cell.
  • the low temperature level of the air-conditioned fresh air mass flow is advantageously used to cool the drive cell. After the drive cell has cooled, the amount of heat returned is dissipated with the exhaust air mass flow.
  • the fresh air mass flow is equal to the exhaust air mass flow.
  • the volume of the fresh air mass flow thus corresponds to the volume of the exhaust air mass flow. This ensures that the cooling energy contained in the fresh air is optimally used, in addition to the air conditioning of the vehicle cabin, it is also used to cool the drive cell. If no exhaust air mass flow is discharged, no fresh air mass flow is also supplied.
  • an additional possibility is that the circulating air mass flow circulating in the passenger cell is almost identical to the total air mass flow located in the passenger cell, minus the exhaust air mass flow. This ensures that all the air discharged from the passenger compartment is used to cool the drive compartment.
  • the average temperature of the exhaust air mass flow differs from the average temperature of the surface of the drive cell by only a few degrees, preferably by a maximum of 5 ° Celsius.
  • the cooling of the drive cell is designed in such a way that the cooling mass flow dissipates just as much heat from the drive cell as depending on the respective one Load case is necessary.
  • the specific heat capacity of the cooling mass flow, which is related to the mass, is fully exploited.
  • the surface of the drive cell is designed to be correspondingly large with regard to optimal heat exchange.
  • the cooling mass flow is discharged to the surroundings as an exhaust air mass flow after cooling the drive cell.
  • the one with an optimal utilization of the specific heat capacity on the temperature The cooling mass flow heated up in the drive cell is immediately discharged into the atmosphere after cooling. This prevents the cabin interior temperature from rising due to the heated cooling mass flow.
  • the passenger cell in the immediate vicinity of the drive cell has a ventilation opening for the cooling mass flow, through which the cooling mass flow is led into the environment as exhaust air.
  • the exhaust air mass flow is regulated by adjusting a flap of the ventilation opening.
  • a circulating air flap for regulating the fresh air mass flow and / or the circulating air mass flow is arranged in the passenger cell.
  • the fresh air supply is thus set between a minimum and a maximum in accordance with the parameters required for cooling the drive cell.
  • the inlet opening is closed with minimal fresh air supply.
  • a cooling fan is assigned to the drive cell for regulating the fresh air mass flow and / or the circulating air mass flow.
  • the cooling fan supports the required dynamics of the air masses in the entire cooling and recirculation system.
  • the cooling mass flow flows through the drive cell and / or the ventilation opening for the exhaust air mass flow can be regulated as a function of the temperature of the cooling mass flow.
  • the heat transport it is advantageous for the heat transport to bring the cooling mass flow into contact with the drive cell for as long as possible.
  • the flap of the ventilation opening can be closed and thus the exhaust air mass flow can be regulated depending on the temperature of the cooling mass flow.
  • a drive cell 2 In the rear area of a passenger cell 1, a drive cell 2 is provided, which is designed as a high-performance battery or as a fuel cell system. To cool the drive cell 2, a cooling mass flow 3.2 flows through the drive cell 2. The heated cooling mass flow 3.2 is discharged into the atmosphere as an exhaust air mass flow 3.3 via a ventilation opening 1.1.
  • a fresh air mass flow 3.1 is conducted into the passenger compartment 1 via an inlet opening 1.2.
  • the fresh air mass flow 3.1 is identical in volume to the exhaust air mass flow 3.3.
  • the fresh air mass flow 3.1 is cooled by means of an air conditioning system 4 and supplied to the circulating air mass flow 3.4 circulating in the passenger compartment 1.
  • the cooling mass flow 3.2 is regulated as a function of the cooling capacity required for the drive cell 2.
  • the cooling mass flow 3.2 is branched off from the air mass flow 3.4 circulating in the passenger compartment 1, and with the removal of heated cooling air 3.2 in the form of exhaust air 3.3, fresh air 3.1 is again conducted into the passenger compartment 1.
  • the air volume located in the passenger compartment 1 remains approximately constant.
  • the amount of fresh air mass flow 3.1 is adapted to the necessary cooling capacity of the drive cell 2. It is important that any air mass flow introduced into the passenger compartment 1 is ultimately used to cool the drive compartment 2. If no exhaust air mass flow 3.3 is discharged, no fresh air mass flow 3.1 has to be supplied to cool the drive cell.
  • This cooling system enables precisely controllable and energy-saving cooling of the drive cell.

Abstract

La présente invention concerne un système de ventilation permettant de refroidir une pile d'entraînement (2) conçue sous forme de dispositif de piles à combustible d'une automobile. Le courant massique d'air frais (3.1) conduit dans un habitacle et refroidi au moyen d'un dispositif de climatisation (4) est fourni au courant massique d'air ambiant (3.4) et est finalement utilisé comme courant massique de refroidissement (3.2) pour refroidir la pile d'entraînement (2). La même quantité de courant massique d'air frais (3.1) est introduite dans l'habitacle que celle séparée après le refroidissement de la pile d'entraînement (2) en courant massique d'air d'évacuation (3.3).
