A heat exchanger includes a metal base defining a heat exchange channel for flowing at least one of a refrigerant and a coolant therein, and a coating layer coated at least a part of an outer surface of the metal base. The coating layer includes sol particles and an antibacterial material, where the sol particles include silica. The antibacterial material includes a rare earth element oxide. By combining the antibacterial agent containing the rare earth element oxide with sol, the advantages of each component can be fully utilized. On the one hand, it is easier to attach the antibacterial material via the sol, and on the other hand a surface of the metal base of the heat exchanger can have a good antibacterial and mold-inhibiting effects, which is beneficial to cost reduction.
