摘要:
A system for a motor vehicle for heating and/or cooling a battery and a motor vehicle interior is provided that includes a first coolant circuit thermally coupled to the battery, a second coolant circuit for heating the motor vehicle interior having an air heat exchanger for outputting heat from the second coolant circuit to the air of the interior of the motor vehicle, and a heating unit for heating the second coolant circuit. The first coolant circuit and the second coolant circuit are thermally coupled to each other for heating the battery using heat from the second coolant circuit and/or for cooling the air of the motor vehicle interior, in that heat from the second coolant circuit can be fed to the first coolant circuit by the circuit heat exchanger or the mixing valve.
摘要:
A heat exchanger, in particular a heating element for motor vehicles, is provided that includes a block that has flat tubes and corrugated fins and a collecting tank on the inlet side and on the outlet side, wherein the flat tubes comprise flat sides having embossed vortex generators, and a coolant can flow through the flat tubes. The flat tubes can have an inner diameter in the range of 0.9 to 1.2 mm, preferably of 1.0 mm, and the corrugated fins can have a height in the range of 6.3 to 8.0 mm, preferably of 8.3 mm.
