Description

Technical Field

[0001] The invention 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 equalizing 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 ensured, 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 urgently necessary to develop a structure that ensures a stable and reliable connection between the heat pipes and the upper cover. Summary of the invention

[0003] In view of the above problems, the present invention 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, thereby 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-averaging 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 of which comprises 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 protrusion;

[0008] Each heat pipe corresponds to a connection positioning mechanism, and a plurality of heat pipe positioning holes are provided on the upper cover plate. 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 in close contact with 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 fixedly connected 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, ensuring 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 stably arranged after connection.

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