[0031] Please refer to Figures 1-5 The present embodiment provides a heat exchanger outflow pipe group 100, which comprises a collecting pipe 110 and an outflow pipe 120.

[0032] The outer periphery of the collecting pipe 110 is provided with a flow guide opening 111, one end of the outflow pipe 120 is connected to the flow guide opening 111, and the outflow pipe 120 is in communication with the inside of the collecting pipe 110.

[0033] Please refer to Figures 1-5 The working principle of the heat exchanger outflow pipe group 100 is as follows:

[0034] Firstly, the heat exchanger outflow pipe group 100 is applied to the heat exchanger, which functions to collect the oil liquid in the flow guide pipe or the heat exchange pipe, and the collected oil liquid is guided out through the outflow pipe 120, thereby forming an oil liquid circulation passage in the heat exchanger;

[0035] In this process, in order to enable the oil liquid to be smoothly guided from the collecting pipe 110 to the outflow pipe 120, the outer periphery of the collecting pipe 110 in the embodiment is provided with a flow guide opening 111, and the purpose of the flow guide opening 111 is to form a position for positioning connection with the outflow pipe 120. One end of the outflow pipe 120 is connected to the flow guide opening 111 and is in communication with the inside of the collecting pipe 110. In this way, the end of the outflow pipe 120 is connected to the flow guide opening 111, thereby avoiding the situation that part of the outflow pipe 120 extends into the collecting pipe 110, which increases the flow resistance in the collecting pipe 110 and affects the flow of the oil liquid in the collecting pipe 110 to the outflow pipe 120.

[0036] Therefore, the heat exchanger outflow pipe group 100 is applied to the heat exchanger, which has a simple structure, can reduce the flow resistance in the collecting pipe 110, improve the oil guiding efficiency of the collecting pipe 110 to the outflow pipe 120, and thus improve the oil return efficiency.

[0037] Further, please refer to Figures 1-5 In the embodiment, when the outflow pipe 120 is connected to the collecting pipe 110, as known from the foregoing, the flow guide opening 111 is provided on the outer periphery of the collecting pipe 110. Based on this, it is known that the diameter of the collecting pipe 110 is greater than the diameter of the outflow pipe 120. On this basis, in order to avoid the situation that the end of the outflow pipe 120 extends into the collecting pipe 110 after extending into the flow guide opening 111 when the outflow pipe 120 is connected to the flow guide opening 111, the end of the outflow pipe 120 for connection with the flow guide opening 111 is provided with a matching curved surface 121 matching the edge of the flow guide opening 111. The purpose of this arrangement is to enable the oil liquid in the collecting pipe 110 to be smoothly delivered to the outflow pipe 120, i.e., to reduce the flow resistance at the connection between the collecting pipe 110 and the outflow pipe 120, thereby improving the oil guiding efficiency.

[0038] On the basis of the above structure, in order to improve the stability of the connection in the process of connection, therefore, the outer periphery of the end of the outflow pipe 120 for connecting with the flow guide port 111 is provided with a boss head 122, the boss head 122 is used to abut against the outer peripheral surface of the collecting pipe 110. Through the setting of the boss head 122, the positioning and connecting efficiency can be improved, and in the process of use, the strength and stability of the connection can be increased through the setting of the boss head 122. Moreover, when the boss head 122 is arranged, along the axis direction of the outflow pipe 120, the distance from the boss head 122 to the end of the outflow pipe 120 for connecting with the flow guide port 111 is less than or equal to the wall thickness of the collecting pipe 110. The purpose of such a setting mode is that the structure of the boss head 122 can be adapted to the setting of the arc-shaped structure of the end of the outflow pipe 120, so that when the outflow pipe 120 is connected with the collecting pipe 110, the end of the outflow pipe 120 is located in the flow guide port 111 and adapts to the shape profile of the flow guide port 111 when the boss head 122 abuts or connects with the collecting pipe 110, avoiding the situation that part of the outflow pipe 120 is mistakenly inserted into the collecting pipe 110.

[0039] Based on the above content, please refer to Figures 1-5 In the embodiment, the end of the outflow pipe 120 is connected to the flow guide port 111 on the collecting pipe 110. The purpose of such a setting mode is to avoid that part of the outflow pipe 120 extends into the collecting pipe 110. On the basis of this, in order to improve the sealing property of the connection and the stability of the connection, the end of the outflow pipe 120 inserted into the flow guide port 111 of the collecting pipe 110 can be welded, or the boss head 122 on the outflow pipe 120 which is shaped according to the collecting pipe 110 can be welded and sealed.

[0040] In addition, a sealing ring can be arranged between the contact surface of the boss head 122 and the collecting pipe 110, or a sealing ring can be arranged between the contact surface of the collecting pipe 110 and the outflow pipe 120.

[0041] Further, please refer to Figures 1-5 On the basis of the above structure, in order to improve the positioning efficiency, the outer periphery of the end of the outflow pipe 120 for connecting with the flow guide port 111 can be provided with a first positioning part, and the inner peripheral surface of the flow guide port 111 is provided with a second positioning part which is positioned and matched with the first positioning part. Moreover, one of the first positioning part and the second positioning part is a positioning protrusion, and the other is a positioning groove.

[0042] The reason for such a setting mode is that the end of the outflow pipe 120 is adapted to the profile of the flow guide port 111, and the shape of the boss head 122 is adapted to the outer peripheral profile of the collecting pipe 110. Therefore, in order to improve the positioning and assembling efficiency, the first positioning part and the second positioning part are arranged in such a way to improve the assembling efficiency.

[0043] Further, please refer to Figures 1-5 In this embodiment, in order to improve the flow efficiency of the oil in the manifold 110 to the outflow pipe 120, and reduce the efficiency of the oil in the manifold 110 to the outflow pipe 120, the inner wall of the end of the outflow pipe 120 connected to the flow guide 111 is provided with an arc-shaped transition surface. The purpose of such a design is to enable the oil in the manifold 110 to be smoothly delivered to the outflow pipe 120, i.e. to reduce the flow resistance at the connection between the manifold 110 and the outflow pipe 120, thereby improving the flow efficiency of the oil.

[0044] On the basis of the above structure, in order to facilitate the communication between the manifold 110 and the external oil return pipe for oil collection, the manifold 110 is provided with a plurality of flow ports 112 along the axial direction thereof. In addition, a plurality of partition grooves 113 for mounting partition plates are provided on the manifold 110.

[0045] Based on the above, please refer to Figures 1-5 The present embodiment also provides a heat exchanger, which comprises the heat exchanger outflow pipe group 100 described above.

[0046] The heat exchanger can reduce the flow resistance in the manifold 110 and improve the oil guiding efficiency of the manifold 110 to the outflow pipe 120, thereby improving the oil return efficiency and the heat exchange efficiency.

[0047] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which shall be covered within the protection scope of the present application.
