1. An inductive power transfer pad, comprising:
a first conductor arrangement configured to generate an electromagnetic field or receive an electromagnetic field during an inductive power transfer;
an airflow generating system that is configured to generate an airflow during an inductive power transfer, a pressure generating unit of the airflow generating system being configured to suck in air from the surroundings so that the air flows through an interior space of the inductive power transfer pad and directed back into the surroundings of the inductive power transfer pad through an airflow outlet portion, wherein the inductive power transfer pad is configured to direct at least a part of the airflow into the surroundings along a surface of the inductive power transfer pad which faces a second conductor arrangement during the inductive power transfer, the second conductor arrangement configured to:
receive the electromagnetic field generated by the first conductor arrangement, when the first conductor arrangement is configured to generate the electromagnetic field, or
generate the electromagnetic field to be received by the first conductor arrangement, when the first conductor arrangement is configured to receive the electromagnetic field.
