Abstract: A cooling system for a fuel cell of a motor vehicle may include a closed coolant circuit through which a coolant is circulatable, a heat exchanger fluidically incorporated in the coolant circuit for cooling the coolant, an open sprinkler circuit through which a sprinkler fluid is flowable for cooling the heat exchanger, and a channel structure fluidically incorporated in the sprinkler circuit. The heat exchanger may include an air inlet surface, an air outlet surface, and a plurality of cooling tubes. The coolant may be flowable through the heat exchanger via the plurality of cooling tubes. Air may be flowable through the heat exchanger from the air inlet surface to the air outlet surface. The channel structure may include a plurality of channels, which may each include a plurality of outlet nozzles via which the sprinkler fluid is appliable to the plurality of cooling tubes.

Abstract: A high-voltage heater for a motor vehicle for heating a coolant is disclosed. The high-voltage heater includes at least two flat tubes that are flowable through by the coolant and at least one heating element. The at leas two flat tubes and the at least one heating element are alternatingly stacked on top of one another in a stacking direction to form a stack. The at least one heating element is connected at least to one of the adjacent flat tubes in the stack in a heat-transferring manner.

Abstract: An intercooler may include a condensate collector configured to collect condensate precipitated in the intercooler. The condensate collector may be separate from the intercooler and disposed below the intercooler. The condensate collector may include at least one expansion chamber, the at least one expansion chamber arranged above an inlet and an outlet of the condensate collector during operation of the intercooler.

Abstract: A charge air cooler for an internal combustion engine may include a heat exchanger having a plurality of fluid paths through which charge air to be cooled is flowable. The charge air cooler may also include a collector attached to the heat exchanger and communicating with the fluid paths. A lower region of the collector may be configured as a condensate receiving zone for receiving condensed charge air. At least one pipe body may be arranged in the collector and may delimit a fluid channel through which condensed and non-condensed charge air may be flowable. An opening may be formed in the at least one pipe body and may fluidically connect the fluid channel to the condensate receiving zone.
