Description

Technical Field

[0001] This utility model relates to the field of water-cooled plate technology, and in particular to a water-cooled plate that prevents channel expansion. Background Technology

[0002] A water-cooled plate, also known as a liquid-cooled plate, is a component of a water-cooled radiator. Its principle is to form flow channels within a metal plate. Electronic components are mounted on the surface of the water-cooled plate (with a heat-conducting medium coated in between). Coolant enters from the inlet and flows out from the outlet, carrying the heat from the components.

[0003] Existing water-cooled plates have a fixed heat dissipation channel structure. Depending on the size of the water-cooled plate, the length and degree of meandering of the channel vary. During operation, a drive pump propels the coolant towards the inlet, allowing it to enter the heat dissipation channel and then exit through the outlet, achieving rapid heat dissipation for the water-cooled plate and, consequently, for electronic components. When the water-cooled plate is not in operation, some coolant may remain in the heat dissipation channel. In low-temperature conditions, this can cause the coolant to freeze, leading to expansion of the channel and potential cracking. This can result in leakage and render the water-cooled plate unusable, causing unnecessary losses. Therefore, improvements are needed. Utility Model Content

[0004] The main purpose of this utility model is to provide a water-cooled plate that prevents the expansion of the heat dissipation channel, and aims to provide a water-cooled plate that can effectively prevent the expansion of the heat dissipation channel due to icing.

[0005] To achieve the above objectives, this utility model proposes a water-cooled plate for preventing channel expansion, comprising a base and a cover plate. The base is provided with a heat dissipation channel, and the cover plate covers the heat dissipation channel. A heat-conducting surface for contacting external electronic components is formed on the upper side of the cover plate. The base is also provided with an inlet and an outlet connected to the heat dissipation channel, and a blind hole channel is provided inside the heat dissipation channel.

[0006] Specifically, the blind hole channel includes multiple channel body segments, each channel body segment having a blind hole end and a closed end, with the blind hole end facing the outlet direction.

[0007] Specifically, the cover plate is provided with a connection port that communicates with the heat dissipation channel, and the connection port is provided with an adapter to form the inlet or the outlet.

[0008] Specifically, the adapter includes a connector body, on which a first connecting end and a second connecting end are provided. The first connecting end is used to connect to an external pipe, and the second connecting end is used to connect to the connection port so that the connector body is located at the upper end of the cover plate.

[0009] Specifically, the base is recessed inward on the side facing the cover plate to form the heat dissipation channel, and the side of the base away from the cover plate forms a channel protrusion.

[0010] Specifically, the edge of the cover plate is provided with a baffle extending toward the base. When the cover plate is closed with the base, the baffle extends to the bottom of the base, and the extension length of the baffle is greater than the length of the flow channel protrusion.

[0011] Specifically, both the base and the cover plate are provided with corresponding mounting holes, through which external electronic components are fixed to the cover plate.

[0012] Specifically, the cover plate is rectangular in shape, and a heat-conducting connection surface is formed on the side of the cover plate away from the base.

[0013] This utility model provides a blind hole channel in the heat dissipation channel so that when the water-cooled plate is in a static state and becomes supercooled and icy, the frozen coolant can be contained through the blind hole channel, preventing the coolant from expanding in the heat dissipation channel and causing irreversible damage to the heat dissipation channel, thereby improving the service life of the water-cooled plate.

[0024] like Figures 1 to 6 As shown, a water-cooled plate for preventing channel expansion includes a base 10 and a cover plate 20. The base 10 is provided with a heat dissipation channel 11, and the cover plate 20 covers the heat dissipation channel 11. A heat-conducting surface for contact with external electronic components is formed on the upper side of the cover plate 20. The base 10 is also provided with an inlet and an outlet connected to the heat dissipation channel 11. A blind hole channel 30 is provided in the heat dissipation channel 11. When the water-cooled plate is in use, the coolant flows into the heat dissipation channel 11 through the inlet. At this time, the coolant exchanges heat with the base 10 and the cover plate 20 in the heat dissipation channel 11. After the heat exchange is completed, the coolant flows out through the outlet, thus realizing the coolant circulation. When the water-cooled plate is not in use, some coolant will still exist in the heat dissipation channel 11. When supercooling occurs, the coolant will condense and expand. At this time, the coolant that has not yet condensed can be squeezed, so that some coolant enters the blind hole channel 30. The blind hole channel 30 contains and condenses the coolant, thereby strengthening the protection of the heat dissipation channel 11 and preventing irreversible damage to the heat dissipation channel 11 caused by coolant condensation. This prevents the heat dissipation channel from expanding and improves the service life of the water-cooled plate.

[0025] The blind hole channel 30 includes multiple channel body segments, each of which has a blind hole end 31 and a closed end 32. The blind hole end 31 faces the outlet direction. In this embodiment, multiple channel body segments are provided in the heat dissipation channel. A blind hole is provided at one end of the channel body to form the blind hole end 31. At the same time, the blind hole end 31 faces the outlet direction. When the water-cooled plate is in normal use, the coolant will not enter the blind hole channel 30 through the blind hole end 31. When the water-cooled plate is in a static state, if it encounters supercooling, the coolant can enter the blind hole channel 30 through the blind hole of the blind hole end 31. The volume of the heat dissipation channel 11 is increased through the blind hole channel 30, thereby preventing the expansion of the heat dissipation channel 11 caused by the condensed coolant.

[0026] The cover plate 20 is provided with a connection port 22 that communicates with the heat dissipation channel 11. The connection port 22 is provided with an adapter 40 to form an inlet or outlet. In this embodiment, the cover plate 20 is provided with a connection port 22 so that the adapter 40 can be connected to the water cooling plate through the connection port 22 to form an inlet or outlet, thereby facilitating the connection of external pipes with the heat dissipation channel 11 through the adapter 40.

[0027] The adapter 40 includes an adapter body with a first connecting end 41 and a second connecting end 42. The first connecting end 41 is used to connect to an external pipe, and the second connecting end 42 is used to connect to a connection port 22 so that the adapter body is located at the upper end of the cover plate 20. In this embodiment, the adapter body is provided with a first connecting end 41 and a second connecting end 42. The first connecting end 41 is connected to an external pipe, and the second connecting end 42 is connected to a connection port 22, thereby realizing the flow and circulation of coolant and heat dissipation channel 11.

[0028] A heat dissipation channel 11 is formed by an inward recess on the side of the base 10 facing the cover plate 20, and a channel protrusion 12 is formed on the side of the base 10 away from the cover plate 20. A baffle 21 extending towards the base 10 is provided on the edge of the cover plate 20. When the cover plate 20 is closed with the base 10, the baffle 21 extends to the bottom of the base 10, and the extension length of the baffle 21 is greater than the length of the channel protrusion 12. In this embodiment, the heat dissipation channel 11 is formed by an inward recess on the base 10, and then the cover plate 20 is closed with the heat dissipation channel 11 to form a stable and sealed channel space. The channel protrusion 12 is provided on the substrate. By providing the baffle 21 on the cover plate 20, and the length of the baffle 21 is greater than the outward protrusion length of the channel protrusion 12, it is convenient to protect the heat dissipation channel 11 by the baffle 21 during installation, and prevent external forces from changing the volume of the heat dissipation channel 11 or deforming the heat dissipation channel 11.

[0029] Both the base 10 and the cover plate 20 are provided with corresponding mounting holes, through which external electronic components are fixed to the cover plate 20. The cover plate 20 is rectangular, and a heat-conducting connection surface 23 is formed on the side of the cover plate 20 away from the base 10. In this embodiment, the mounting holes facilitate the stable fixing of external electronic components to the heat-conducting connection surface 23 of the cover plate 20, thereby improving the stability of the water-cooled plate after installation and thus improving the performance of the water-cooled plate.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
