Description

Technical Field

[0001] The utility model relates to the technical field of radiator structures, in particular to a sintered structure of a heat pipe and an upper cover plate of a radiator. Background Art

[0002] The existing three-dimensional radiator's temperature distribution plate structure and the connection method of the heat pipe are not strong. The heat pipe is directly inserted and positioned into the mounting hole of the upper cover. In actual use, the insertion depth of the heat pipe and the upper cover at the height position cannot be reliably guaranteed, which can easily lead to uneven tops of the heat pipes. In actual heat exchange, the tops of the heat pipes are easily subjected to external forces, causing fractures at the connections and resulting in medium leakage. Therefore, it is urgent to develop a structure that ensures a stable and reliable connection between the heat pipes and the upper cover. Utility Model Content

[0003] In view of the above problems, the utility model provides a sintered structure of a heat pipe and an upper cover plate of a radiator, which makes the connection between the heat pipe and the upper cover plate stable and reliable, ensuring the long-term stable operation of the radiator.

[0004] A sintered structure of a heat pipe and an upper cover plate of a radiator, characterized in that it comprises:

[0005] A temperature distribution plate mechanism, comprising a bottom plate, an upper cover plate, and an internal cavity mechanism;

[0006] a plurality of protruding heat pipes;

[0007] and a plurality of connection and positioning mechanisms, each connection and positioning mechanism comprising a bottom outer ring and a connection sleeve, wherein the bottom of the connection sleeve is provided with a bottom outer ring with a side convexity;

[0008] Each heat pipe corresponds to a connection and positioning mechanism. The upper cover plate is provided with a plurality of heat pipe positioning holes. The bottom of each heat pipe is inserted into the heat pipe positioning hole, and the bottom is not lower than the upper surface of the bottom outer ring. The radial outer ring upper surface of the bottom outer ring is tightly attached to the lower surface of the upper cover plate, and the connecting sleeve is located in the bottom area of ​​the inner cavity of the heat pipe.

[0009] It is further characterized by:

[0010] The bottom of each heat pipe is in close contact with the upper surface of the bottom outer ring, which ensures that the bottom outer ring is fixed to the heat pipe and the upper cover plate respectively after sintering, ensuring a stable and reliable connection;

[0011] The outer wall of the connecting sleeve is in close contact with the corresponding position of the bottom inner wall of the heat pipe to ensure the reliable fixing of the heat pipe and the connecting positioning mechanism;

[0012] The height of the connecting sleeve is greater than the thickness of the upper cover plate, ensuring that the heat pipe is firmly arranged after connection.

[0013] After adopting the technology of the utility model, a connection positioning mechanism is added to the positioning plug-in type of the heat pipe and the upper cover. The bottom outer ring of the heat pipe positioning mechanism can cover the joint between the heat pipe and the upper cover, overcoming the phenomenon that the copper powder between the heat pipe and the upper cover cannot fill the joint. At the same time, a circle of connecting sleeves is provided on the inner ring of the connection positioning mechanism as a reinforcing powder ring, which greatly improves the sintering yield of the finished radiator; makes the connection between the heat pipe and the upper cover stable and reliable, and ensures the long-term and stable operation of the radiator.
