wherein the first pipe is detachably connected to a second side of the installation plate, and the second pipe is detachably connected to a first side of the installation plate opposite to the second side of the installation plate;

wherein the installation plate is provided with a through-hole penetrating the installation plate in a first direction;

the first pipe comprises a first part and a second part that are connected to each other, the first part is located at the second side of the installation plate, and the second part goes through the through-hole and is connected to the second pipe;

wherein the second pipe comprises a second main body and a second flange, and the second flange is connected to an end of the second main body and extends radially outward;

the second flange comprises a receiving chamber in communication with the second main body, and an entire of the second flange is detachably connected to the first side of the installation plate; and

the second part of the first pipe is inserted into the receiving chamber of the second flange;

wherein the heat exchange pipe joint further comprises a second sealing member, the second sealing member is sleeved on an outer circumference of the second part, and the second sealing member is compressed and sandwiched between the installation plate and the second flange so that no gap is formed between the second flange and the installation plate;

wherein the second sealing member comprises at least one through-hole;

wherein a protrusion is provided at a side of the receiving chamber close to the second main body, and the protrusion protrudes radially inward from an inner circumferential surface of the receiving chamber; and

an end of the second part abuts against the protrusion along the first direction; and

wherein an outer surface of the second main body protrudes away from a center of the second part to form another protrusion, and the another protrusion abuts against the protrusion that is located at the end of the second part, and the another protrusion is independent from the protrusion.
