Vehicle with a cooling system for cooling and method for cooling in a vehicle

摘要

A cooling system of a vehicle with a fuel cell includes an absorbent circuit with an absorber tank, a regenerator tank, an absorbent pump and a first pressure reduction means and a coolant circuit with a condenser connected to a steam outlet of the regenerator tank, a second pressure reduction means and an evaporator arranged between a steam inlet of the absorber tank and the second pressure reduction means. The regenerator tank is designed to desorb the coolant in solution in the absorbent by absorbing a first quantity of heat and to introduce it in a vaporous state into the condenser. The evaporator is designed to evaporate the coolant while absorbing a second quantity of heat and to introduce it in the vaporous state into the absorber tank. At least one of the first and of the second quantity of heat could be provided by the fuel cell.

主权项

1. A vehicle comprising a heat emitting device and a cooling system, with the cooling system comprising:
an absorbent circuit, wherein a liquid absorbent is configured to circulate, the absorbent circuit comprising: an absorber tank; a regenerator tank; an absorbent pump; and a first pressure reduction means, wherein the absorber tank is connected by an absorber tank outlet, by way of the absorbent pump, to a regenerator tank inlet; and wherein a regenerator tank outlet is connected by the first pressure reduction means to an absorber tank inlet; and a coolant circuit, wherein a coolant is configured to circulate, the coolant circuit comprising:
a condenser connected to a steam outlet of the regenerator tank;a second pressure reduction means; andan evaporator connected to a steam inlet of the absorber tank and by way of the second pressure reduction means is connected to the condenser; wherein the regenerator tank is configured to desorb the coolant in solution in the absorbent by absorbing a first quantity of heat provided by a first heat source and to introduce the coolant in a vaporous state into the condenser; wherein the evaporator is configured to evaporate the coolant while absorbing a second quantity of heat provided by a second heat source and to introduce the coolant in the vaporous state into the absorber tank; and wherein the first heat source comprises a fuel cell and the second heat source comprises the heat emitting device.
