The existing automobile air conditioner condenser and the oil cooler are two independently arranged parts which are respectively arranged at different parts of an automobile. For example, the patent document in China discloses "a vehicle air conditioner condenser", the publication number CN203501567U of which comprises a condenser, a water tank, a collecting pipe I, a collecting pipe II, a clapboard and a drying bottle; and the pipe-type oil cooler is disclosed as CN202993957U, and comprises an oil cooler core body and an oil cooler oil chamber, wherein the oil cooler core body is assembled and brazed into a whole by an oil cooler main board, a radiating pipe, a radiating belt and a protective plate.
