[0027] Embodiment
[0028] Please refer to Figures 1 - 4 , this embodiment provides a new type of liquid cooling plate, which includes two outer plates 1 arranged at intervals and a flow channel layer 2 fixed between the two outer plates 1. The flow channel layer 2 includes a machining part 3 and a profile outer frame 4 fixed on the peripheral side of the machining part 3. A flow channel 5 is provided in the machining part 3; the outer plate 1 of this embodiment is made of an aluminum plate, which mainly adopts a 5-series / 6-series flat plate with a thickness of 1 mm - 1.5 mm. The ultra-thin thickness and the need for no stamping greatly reduce its cost.
[0029] The machining part 3 and the profile outer frame 4 of this embodiment are made of aluminum materials. Among them, the machining part 3 can be formed by machining an aluminum plate to form the flow channel 5, or directly formed by fixing a plurality of aluminum blocks between the two outer plates 1 to form the flow channel 5. Different from the structure of the stamping die, the formation of the machining part 3 can be unrestricted by shape. After determining the water inlet and outlet of the flow channel 5, the flow channel 5 can be freely designed and processed to restrict the water flow direction. After machining is completed and placed in the corresponding position, it can form a complete closed flow channel 5 with the upper and lower outer plates 1. The outer plate 1 is provided with a water nozzle 6 communicating with the flow channel 5, and the flow channel layer 2 is fixed to the two outer plates 1 by brazing respectively. When brazing and fixing, by placing a brazing filler metal between each pair and then placing it in a brazing furnace, the overall welding can be completed.
[0030] In this way, the upper and lower outer plates 1 of this application can be made with a very thin thickness, saving weight and cost; avoiding the stamping process through a three-layer structure, without the need for mold opening and saving more cost; using profiles and machining parts to plan the flow channel layout, the flow channel design has arbitrariness, greatly improving the design freedom, and using brazing to complete the high reliability of the connection part. Therefore, this application avoids the high mold cost existing in the stamping process itself and the flow channel design limitations of the aluminum profile integrated flow channel process through a new structure.
[0031] As Figures 1 - 4 shown, in some embodiments of the present utility model, the machining part 3 is provided with a flange 7, and the flange 7 is provided with a connection hole 8 communicating with the flow channel 5; the outer plate 1 is provided with a mounting hole 9, and one end of the water nozzle 6 passes through the mounting hole 9 and is embedded in the connection hole 8. The outer side wall of the water nozzle 6 is provided with an external thread, the connection hole 8 is a screw hole, and the water nozzle 6 is threadedly connected to the flange 7. In this way, it is convenient to install and disassemble the water nozzle 6 through threaded connection, and it is convenient to replace the water nozzle 6. In addition to using the threaded connection method, the water nozzle 6 can also be brazed and connected synchronously during brazing.
[0032] As Figures 1 - 4As shown, in some embodiments of the present utility model, a limiting ring 10 is provided on the outer sidewall of the water nozzle 6. The outer diameter of the limiting ring 10 is larger than the diameter of the mounting hole 9, and the limiting ring 10 abuts against the outer sidewall of the outer layer plate 1. By providing the limiting ring 10 in the present utility model, when installing the water nozzle 6, after the limiting ring 10 abuts against the outer sidewall of the outer layer plate 1, the water nozzle 6 cannot rotate further, thus facilitating the proper installation of the water nozzle 6.
[0033] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of this application, this application can be implemented in other specific forms.
[0034] Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application.
