Abstract

A pipe clamp assembly and a heat exchanger having same with the pipe clamp assembly including a first pipe clamp member and a second pipe clamp member. The first pipe clamp member includes a first mounting surface located on a first side of the first pipe clamp member, and a second mounting surface located on a second side, opposite the first side, of the first pipe clamp member, and the second pipe clamp member includes a mounting surface facing the first pipe clamp member, and the mounting surface of the second pipe clamp member and the second mounting surface of the first pipe clamp member are used for clamping a pipe between the mounting surface of the second pipe clamp member and the second mounting surface of the first pipe clamp member. By using the pipe clamp assembly and the heat exchanger, the risk of the inlet pipe and outlet pipe being scrapped due to puncturing from spot-welding and the risk of later failure due to damage to the inlet pipe and outlet pipe from spot-welding are both avoided, and the pipe clamp assembly and heat exchanger are simple to mount and easy to implement.
