[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] Please refer to Figures 1-8This utility model provides a liquid-cooled flow channel heat dissipation component, comprising: a flow channel body 10, within which a liquid-cooled flow channel 11 is provided. The liquid-cooled flow channel 11 can be formed from a profile, for example, the flow channel body 10 can be formed by casting, during which the liquid-cooled flow channel 11 can be formed within the flow channel body 10; alternatively, the flow channel body 10 can also be formed by bending a sheet, and the bent sheet can be welded to form the liquid-cooled flow channel 11; furthermore, the flow channel body 10 can also be formed by other methods, as long as a liquid-cooled flow channel 11 for coolant to flow in and out can be formed within the flow channel body 10. The coolant flowing within the liquid-cooled flow channel 11 can effectively dissipate heat from the power device 100. The outer wall of the flow channel body 10 is provided with a mounting portion for mounting the power device 100. This mounting portion provides support for the power device 100, improving its installation stability. Furthermore, compared to directly mounting the power device 100 onto the side wall of the flow channel body 10, this invention effectively avoids drilling holes in the flow channel body 10 to mount the power device 100, thus ensuring the structural strength and sealing performance of the flow channel body 10 and preventing leakage. In addition, compared to existing solutions that integrally mold the flow channel body 10 into the housing, the flow channel body 10 of this invention can be independently molded, has a simple structure, and does not require complex molding molds, resulting in lower manufacturing costs. It also facilitates the installation of the power device 100 and isolates it from magnetic interference.

[0041] In some embodiments, the mounting portion is configured as a reinforcing rib 50, wherein the reinforcing rib 50 can be integrally formed with the flow channel body 10 and is located on the outer side wall of the flow channel body 10. An elastic element is mounted on the reinforcing rib 50, which may be a sheet or a spring. The elastic element can be mounted on the reinforcing rib 50 by welding or fasteners. The power device 100 is fixed to the reinforcing rib 50 by fasteners. The power device 100 is located between the elastic element and the flow channel body 10. The elastic element can apply a spring force toward the flow channel body 100 to the power device 100, so that the power device 100 can be pressed tightly against the outer side wall of the flow channel body 10 by the elastic element. The fastener may be a screw. By pressing the power device 100 tightly against the outer side wall of the flow channel body 10, not only can the loss of cold energy be reduced, but the cooling effect of the power device 100 can also be effectively improved. Thus, by setting the integrally formed reinforcing rib 50, the power device 100 can be pre-installed on the flow channel body 10, and then the liquid-cooled flow channel heat sink can be installed as a whole by the reinforcing rib 50, thereby facilitating installation and maintenance.

[0042] In some embodiments, the mounting portion is a reinforcing rib 50, and a mounting rack 80 is mounted on the reinforcing rib 50. The mounting rack 80 can be made of plastic, and is used to press and fix the power device 100, so that the power device 100 is tightly attached to the outer side wall of the flow passage body 10. During installation, the power device 100 can be first mounted on the mounting rack 80, and then the mounting rack 80 is connected to the reinforcing rib 50, so that the mounting rack 80 tightly presses the power device 100 against the outer side wall of the flow passage body 10. The mounting rack 80 facilitates the installation of the power device 100.

[0043] In some embodiments, the mounting rack 80 includes a groove-shaped portion 82, which includes a groove bottom surface 821 and two groove side surfaces 822. The groove bottom surface 821 is provided with at least one protrusion 83, which can be integrally formed on the groove bottom surface 821, or can be detachably connected to the groove bottom surface 821, so as to adapt to the installation of different power devices 100, for example, by clamping or threaded connection on the groove bottom surface 821. A row or multiple rows of spaced protrusions 83 can be provided on the groove bottom surface 821, and the housing of the power device 100 is correspondingly provided with at least one groove 110. The power device 100 is embedded in the groove-shaped portion 82 along the two groove side surfaces 822 and is clamped and fixed by the protrusions 83 and the grooves 110. When the power device 100 needs to be maintained, the mounting rack can be first detached from the reinforcing rib, and then the power device 100 can be taken out of the groove-shaped portion 82. Since the power device 100 and the groove-shaped portion 82 are matched by the concave-convex structure, the mounting rack 80 and the power device 100 can be separated by pulling them in opposite directions, so that the mounting rack 80 and the power device 100 can be easily detached and assembled.

[0044] In some embodiments, the liquid cooling flow passage heat dissipation member further includes a shielding wall 20, and each reinforcing rib 50 is perpendicular to the shielding wall 20. For example, when the shielding wall 20 is arranged in the vertical direction, the reinforcing rib 50 is arranged in the horizontal direction. The flow passage body 10, the reinforcing rib 50, and the shielding wall 20 are integrally formed, so as to reduce the assembly between them, and facilitate the overall assembly of the liquid cooling flow passage heat dissipation member on other structures. At least one side of the flow passage body 10 is provided with the shielding wall 20, and the shielding wall 20 and the outer side wall of the flow passage body 10 are provided with a mounting space 21 for mounting the power device 100. For example, the shielding wall 20 is located outside the flow passage body 10, and the shielding wall 20, the flow passage body 10, and the reinforcing rib 20 form a mounting space for accommodating the power device 100. The shielding wall 20 can effectively shield the magnetic interference of the power device 100. When the power device 100 is tightly pressed against the flow passage body by the elastic member, the elastic member is located between the shielding wall 20 and the power device 100.

[0045] In some embodiments, the outer side of the flow channel body 10 is provided with a plurality of reinforcing ribs 50 distributed along the up and down and arranged at intervals, for example, the outer side of the flow channel body 10 is provided with a reinforcing rib 51 and a reinforcing rib 52, the reinforcing rib 52 is arranged at the bottom of the flow channel body 10 and is integrally formed with the bottom of the flow channel body 10, and the reinforcing rib 51 is arranged at the middle position. In this way, the liquid cooling flow channel heat dissipation member can be installed through the reinforcing rib 52, and the power device 100 can be installed through the reinforcing rib 51, and when the liquid cooling flow channel heat dissipation member is installed through the fastener, corresponding mounting holes 511 and mounting holes 521 can be opened in the reinforcing rib 51 and the reinforcing rib 52, wherein the mounting hole 511 is larger than the mounting hole 521, so as to meet the vertical installation of locking and fixing the fastener after passing through the mounting hole 511.

[0046] A certain space is provided between the reinforcing rib 51 and the reinforcing rib 52, so that when the power device 100 is installed on the upper reinforcing rib 51 through the fastener, the space between the reinforcing rib 51 and the reinforcing rib 52 allows the fastener to be arranged inside the liquid cooling flow channel heat dissipation member, which is aesthetically pleasing.

[0047] In addition, the structural strength between the flow channel body 10 and the shielding wall 20 can be improved by the plurality of reinforcing ribs 50. The power device 100 can be directly installed on the uppermost reinforcing rib 50, or indirectly connected to the uppermost reinforcing rib 50 through the mounting bracket 80, that is, the reinforcing rib 50 can also serve as a carrier for the power device 100. The lowermost reinforcing rib 50 can be connected to the structure applied to the liquid cooling flow channel heat dissipation member.

[0048] In addition, when the elastic member or the mounting bracket 80 is not arranged, the power device 100 can be fixed in the mounting space 21 by the glue pouring method after being installed on the mounting portion. In this way, the glue not only fixes the power device 100, but also transfers the heat of the power device 100 to the flow channel body 10 through the glue pouring. When pouring the glue, only the part above the middle reinforcing rib 51 needs to be poured, and the space between the middle reinforcing rib 51 and the bottom reinforcing rib 52 does not need to be poured, so as to save the amount of glue and reduce the cost.
