摘要： 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.

摘要： A manifold for a heat exchanger and a heat exchanger wherein the manifold includes: a pipe having an end portion; an end cover disposed at the end portion of the pipe and closing the end portion of the pipe to define an inner cavity in the pipe; and a discharge passage including: a first end opening into the inner cavity of the pipe, and a second end located at or adjacent to an end of the manifold and positioned at an outer peripheral surface of the manifold. The first end of the discharge passage is located on a side of the end cover facing the inner cavity of the pipe. According to embodiments of the disclosure, the stacking mounting of the heat exchangers in the axial direction of the manifold and the mounting of the heat exchanger with the end cover of the manifold contacting the ground can be achieved.

摘要： Disclosed in the present invention are a manifold assembly and a heat exchanger. The manifold assembly includes a manifold and a connecting tube assembly. The connecting tube assembly includes an adapter and a steering member. The adapter includes: a tubular part located outside the manifold; and a step part protruding inward from the inner surface of the tubular part at the end portion of the tubular part facing the manifold. The steering member includes: an end wall, a connecting wall extending from the end wall along a direction intersecting the axial direction of the manifold, and a step part protruding outward from the connecting wall at the end portion of the connecting wall away from the end wall. The steering member is inserted into a through hole of the manifold by means of an inner hole of the adapter; the side of the step part of the steering member facing the end wall abuts against the step part of the adapter; and the part of the connecting wall inserted into the manifold is provided with openings that penetrate through the connecting wall. According to the manifold assembly of the present invention, direct impact of a fluid from an inlet on a flat tube is avoided, and the manufacturing and assembly processes are simple and the costs are low.
