[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Please refer to Figure 1-Figure 8A liquid-cooling channel heat sink provided by an embodiment of the present invention includes: a channel body 10, a liquid-cooling channel 11 is arranged in the channel body 10, and the liquid-cooling channel 11 can be formed by a profile, for example, the channel body 10 can be formed by casting, and the liquid-cooling channel 11 can be formed in the channel body 10 during the forming process; in addition, the channel body 10 can also be formed by bending a plate, and the plate can be welded and fixed after bending to form the liquid-cooling channel 11; in addition, the channel body 10 can also be formed by other methods, as long as a liquid-cooling channel 11 for the coolant to flow in and out can be formed in the channel body 10. The coolant flowing in the liquid-cooling channel 11 can effectively dissipate heat for 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, and the mounting portion can provide support for the power device 100 to improve the installation stability of the power device 100. Moreover, compared with directly mounting the power device 100 on the side wall of the flow channel body 10, the present invention can effectively avoid drilling holes on the flow channel body 10 to mount the power device 100 by setting the mounting portion on the outer wall of the flow channel body 10, thereby ensuring the structural strength and sealing performance of the flow channel body 10 to prevent leakage. In addition, compared with the existing solution of integrally molding the flow channel body 10 in the shell, the flow channel body 10 of the present invention can be independently molded, and has a simple structure, and does not require a complex molding mold for production, so the manufacturing cost is low. In addition, it is convenient for the installation of the power device 100 and can also isolate the magnetic interference of the power device 100.

[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 on the outer side wall of the flow channel body 10, an elastic member is installed on the reinforcing rib 50, and the elastic member can be selected as a spring, and the elastic member can be installed on the reinforcing rib 50 by welding or fixing with fasteners, and the power device 100 is fixed to the reinforcing rib 50 by fasteners, and the power device 100 is located between the elastic member and the flow channel body 10, and the elastic member can apply an elastic force toward the flow channel body 10 to the power device 100, so that the power device 100 can be pressed against the outer side wall of the flow channel body 10 through the elastic member, wherein the fastener can be selected as a screw, and by pressing the power device 100 against the outer side wall of the flow channel body 10, not only the loss of cold can be reduced, but also the cooling effect of the power device 100 can be effectively improved; in this way, 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 through the reinforcing rib 50, thereby facilitating installation and maintenance.

[0042] In some embodiments, the mounting portion is configured as a reinforcing rib 50, and a mounting frame 80 is mounted on the reinforcing rib 50. The mounting frame 80 may be a plastic frame, and the mounting frame 80 is used to press and fix the power device 100, and to make the power device 100 close to the outer wall of the flow channel body 10. During installation, the power device 100 may be first mounted on the mounting frame 80, and then the mounting frame 80 may be connected to the reinforcing rib 50, so that the mounting frame 80 presses the power device 100 close to the outer wall of the flow channel body 10. The mounting frame 80 can facilitate the installation of the power device 100.

[0043] In some embodiments, the mounting frame 80 includes a groove-shaped portion 82, the groove-shaped portion 82 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, the protrusion 83 can be integrally formed on the groove bottom surface 821, or the protrusion 83 can be connected to the groove bottom surface 821 in a detachable manner to facilitate the installation of different power devices 100, for example, by being snap-fitted or threadedly connected to the groove bottom surface 821. One or more rows of spaced-apart protrusions 83 may be provided on the bottom surface 821 of the groove, and at least one groove 110 is correspondingly provided on the shell of the power device 100. The power device 100 is embedded in the groove portion 82 along the two groove side surfaces 822 and fixed by the protrusions 83 and the groove 110. When the power device 100 needs to be maintained, the mounting frame may be removed from the reinforcing ribs first, and then the power device 100 may be taken out of the groove portion 82. Since the power device 100 and the groove portion 82 are in a mating relationship through a concave-convex structure, the mounting frame 80 and the power device 100 may be directly pulled in opposite directions to separate the two, so the power device 100 has the advantage of convenient assembly and disassembly.

[0044] In some embodiments, the liquid-cooled channel heat sink further comprises 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, wherein the channel body 10, the reinforcing rib 50 and the shielding wall 20 are integrally formed to reduce the assembly between the three, thereby facilitating the overall assembly of the liquid-cooled channel heat sink on other structures. The shielding wall 20 is provided on at least one side of the channel body 10, and an installation space 21 for installing the power device 100 is provided between the shielding wall 20 and the outer side wall of the channel body 10. For example, the shielding wall 20 is located on the outer side of the channel body 10, and the shielding wall 20, the channel body 10 and the reinforcing rib 20 enclose an installation space for accommodating the power device 100. The shielding wall 20 can effectively isolate the magnetic interference of the power device 100. When the power device 100 is pressed against the channel body by the elastic member, the elastic member can be 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 up and down and arranged at intervals. For example, the outer side of the flow channel body 10 is provided with reinforcing ribs 51 and 52. The reinforcing ribs 52 are arranged at the bottom of the flow channel body 10 and are integrally formed with the bottom of the flow channel body 10. The reinforcing ribs 51 are arranged in the middle position. In this way, the liquid-cooled flow channel heat sink can be installed through the reinforcing ribs 52, and the power device 100 can be installed through the reinforcing ribs 51. When the liquid-cooled flow channel heat sink is installed through fasteners, corresponding mounting holes 511 and mounting holes 521 can be opened in the reinforcing ribs 51 and the reinforcing ribs 52, wherein the mounting hole 511 is larger than the mounting hole 521, so as to meet the requirement of vertical installation after the fastener is passed through the mounting hole 511 and locked and fixed in the mounting hole 521.

[0046] A certain space is provided between the reinforcing ribs 51 and 52. Thus, when the power device 100 is installed on the upper reinforcing rib 51 by means of fasteners, the space between the reinforcing ribs 51 and 52 allows the fasteners to be disposed inside the liquid-cooling channel heat sink, resulting in an aesthetically pleasing installation.

[0047] In addition, the structural strength between the flow channel body 10 and the shielding wall 20 can be improved by using multiple reinforcing ribs 50. The power device 100 can be directly mounted on the uppermost reinforcing rib 50, or can be indirectly connected to the uppermost reinforcing rib 50 through the mounting frame 80, that is, the reinforcing rib 50 can also play a role in supporting the power device 100, and the lowermost reinforcing rib 50 can be connected to the structure applied to the liquid cooling flow channel heat sink.

[0048] In addition, when the elastic member or the mounting frame 80 is not provided, after the power device 100 is installed in the mounting portion, it can be fixed in the mounting space 21 by means of glue pouring. In this way, the glue pouring can not only fix the power device 100, but also transfer 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 reinforcement rib 51 needs to be poured, and the space between the middle reinforcement rib 51 and the bottom reinforcement rib 52 is not needed, so as to save the amount of glue pouring and thus reduce the cost.

[0049] The following description will be made by taking the flow channel body 10 as a U-shaped structure as an example. Figures 1 to 3As shown, the cross-section of the flow channel body 10 can be optionally rectangular, the cross-section of the liquid-cooling flow channel 11 along the direction perpendicular to the flow of the coolant is rectangular, and a shielding wall 20 is provided on the outer side of the U-shaped structure. The structure of the shielding wall 20 is correspondingly a U-shaped wall, and a U-shaped installation space 21 is formed between the U-shaped wall and the U-shaped flow channel body 10. The lower end of the U-shaped wall is connected to the outer side of the bottom of the flow channel body 10, and the U-shaped wall can also be set in the U-shaped groove of the flow channel body 10, that is, the lower end of the U-shaped wall is connected to the bottom of the inner plate of the flow channel body 10, wherein the shielding wall 20 and the flow channel body 10 can be selected as an integrally formed structure, for example, integrally formed by a profile.

[0050] It should be noted that the above-mentioned embodiment only takes the U-shaped flow channel body 10 as an example. In addition, the flow channel body 10 can also be a straight-line, S-shaped or L-shaped structure, wherein at least part of the section of the flow channel body 10 is at least one of the straight-line, S-shaped and L-shaped shapes, and the specific selection can be made according to actual needs, wherein the shape of the shielding wall 20 is consistent with the shape of the flow channel body 10.

[0051] For example, two reinforcing ribs 50 can be set between the shielding wall 20 and the flow channel body 10, one of the reinforcing ribs 50 can be located in the middle of the installation space 21, or in the lower middle or upper position, and the other reinforcing rib 50 is located at the bottom of the installation space 21, respectively denoted as the middle reinforcing rib 51 and the bottom reinforcing rib 52, wherein each reinforcing rib 50 is preferably perpendicular to the shielding wall 20, for example, the shielding wall 20 extends in the vertical direction, and the reinforcing rib 50 extends in the horizontal direction, so as to increase the strength of the shielding wall 20 in the horizontal direction.

[0052] When the flow channel body 10 and the shielding wall 20 are connected by the middle reinforcement rib 51 and the bottom reinforcement rib 52, a mounting hole can be set on the middle reinforcement rib 51, and the power device 100 can be directly or indirectly installed in the mounting hole. In addition, the power device 100 can also be connected in the power device 100 space by welding or bonding. Preferably, the power device 100 is installed by fasteners or mounting brackets 80, so as to facilitate the disassembly and maintenance of the power device 100; wherein a screw hole is provided on the bottom reinforcement rib 52, and the bottom reinforcement rib 52 can be penetrated through the screw hole by screws 60 to realize the installation of the liquid-cooled flow channel heat sink, for example, it can be installed on the bottom shell 70 of the shell by screws 60.

[0053] In order to facilitate the connection of the mounting frame 80 to the reinforcing rib 50, a connecting shaft 81 can be provided at the bottom of the mounting frame 80, and the connecting shaft 81 can be inserted into a mounting hole provided on the middle reinforcing rib 51, and the number of mounting holes can be selected to be multiple. Figures 4 to 6As shown, in order to facilitate fixing the liquid-cooling channel heat sink on the bottom shell 70, the screw holes set on the bottom reinforcement rib 52 correspond to the mounting holes one by one to facilitate the screwing of the screw 60, wherein the aperture of the screw hole is smaller than the aperture of the mounting hole. During installation, after the screw 60 passes through the mounting hole, it can be connected to the screw hole and connected to the bottom shell 70.

[0054] In some embodiments, the inlet of the liquid-cooling flow channel 11 is provided with a liquid inlet joint 30, and the outlet of the liquid-cooling flow channel 11 is provided with a liquid outlet joint 40. The liquid inlet joint 30 and the liquid outlet joint 40 both include a first end plate 31, a second end plate 33 and a connecting portion 32. The first end plate 31 is provided with a first through hole connected to the connecting portion 32, and the second end plate 33 is provided with a second through hole connected to the connecting portion 32. The first end plate 31 is connected to the flow channel body 10, and the connecting portion 32 is connected to the liquid-cooling flow channel 11 through the first through hole. The second end plate 33 is provided with a connecting portion, which is used to directly or indirectly connect to a bearing portion supporting the flow channel body 10, for example, the bearing portion is a bottom shell 70 of the shell, and the connecting portion can be a connecting hole set on the second end plate 33. During installation, bolts can be passed through the connecting holes on the second end plate 33, and the bolts will also be passed through the bottom shell 70, thereby realizing the installation of the liquid-cooling flow channel heat sink; wherein, the first end plate 31 and the second end plate 33 are connected at an angle, and the present embodiment is preferably connected at a right angle. In this way, by rotating the liquid inlet joint 30 and the liquid outlet joint 40, the orientation of the liquid inlet of the liquid inlet joint 30 and the liquid outlet of the liquid outlet joint 40 can be changed. For example, when the inlet and outlet of the liquid-cooling channel 11 are both set to be rectangular, by rotating the liquid inlet joint 30 and the liquid outlet joint 40 by 0 degrees and 180 degrees for installation, the liquid inlet of the liquid inlet joint 30 and the liquid outlet of the liquid outlet joint 40 can be set downward or upward; when the inlet and outlet of the liquid-cooling channel 11 are both set to be square, by rotating the liquid inlet joint 30 and the liquid outlet joint 40 by 0 degrees, 90 degrees, 180 degrees, and 270 degrees, the liquid inlet of the liquid inlet joint 30 and the liquid outlet of the liquid outlet joint 40 can be set downward, or to the left, or to the top, or to the right. In this way, the needs of different installation scenarios of the liquid inlet and outlet orientations can be met without changing the structure of the liquid inlet joint 30 and the liquid outlet joint 40.

[0055] In order to reduce the number of parts and facilitate installation, the first end plate 31, the second end plate 33 and the connecting portion 32 can be designed to be integrally formed, and the first end plate 31 can be connected to the inlet or outlet of the liquid-cooling channel 11 by welding. In addition, in order to meet different installation orientation scenarios of the liquid inlet and the liquid outlet, the first end plate 31 and the channel body 10 can be designed as a detachable connection structure, for example, threaded holes are set at the ends of the inlet and the outlet of the channel body 10, and the first end plate 31 is provided with holes corresponding to the threaded holes. Specifically, the rotation direction of the liquid inlet connector 30 and the liquid outlet connector 40 can be changed. When facing different installation scenarios, the liquid inlet connector 30 and the liquid outlet connector 40 with different orientations can be selected to be connected at the inlet and outlet of the channel body 10.

[0056] In order to improve the connection stability of the first end plate 31, the first end plate 31 is also connected to the shielding wall 20. For example, when the cross section of the flow channel body 10 along the vertical direction is rectangular, the first end plate 31 can be selected as a rectangular plate. The size of the first end plate 31 is larger than the cross-sectional size of the flow channel body 10. One side of the first end plate 31 can be fixed to the shielding wall 20, for example, by brazing welding. By fixing the first end plate 31 to the shielding wall 20, the connection strength of the shielding wall 20 and the first end plate 31 can be improved. The lower surface of the second end plate 33 is higher than the bottom surface of the flow channel body 10. When the flow channel body 10 is installed on the bottom shell 70, there is a certain gap between the second end plate 33 and the bottom shell 70. This gap is suitable for connecting the liquid inlet pipe or the liquid return pipe.

[0057] To facilitate connection, a plurality of connecting blocks 71 and two pads 72 may be provided on the bottom shell 70. The connecting blocks 71 and the pads 72 may be integrally formed with the bottom shell 70. The screw holes on the bottom reinforcement rib 52 correspond to the hole positions on the connecting blocks 71 to facilitate the connection of the screws 60. The liquid inlet interface and the liquid outlet interface correspond to a pad 72 respectively. A through hole connected to the connecting portion 32 is provided in the pad 72. Correspondingly, holes corresponding to the through holes are also provided on the bottom shell 70 to facilitate the delivery of the coolant. Usually, the thickness of the bottom shell 70 is relatively thin. By providing the connecting blocks 71 and the pads 72, the connection stability of the liquid-cooling channel heat sink can be improved.
