[0028] Please also read Figures 1 to 7 The inductor element liquid cooling radiator provided by the utility model is now described. The inductor element liquid cooling radiator comprises a heat dissipation housing 1, the heat dissipation housing 1 has an accommodating cavity 11 which opens upward and is used to place the inductor element, two opposite side plates and a bottom plate of the heat dissipation housing 1 are respectively provided with cooling grooves for accommodating cooling liquid, two opposite inner side walls of the accommodating cavity 11 are respectively used to contact with the two end surfaces of the inductor element to cool the inductor element, and the outer wall of the heat dissipation housing 1 is provided with a liquid inlet 12 and a liquid outlet 13 which are connected with the cooling groove.

[0029] Compared with the prior art, the liquid-cooled radiator for inductor elements provided in the present embodiment utilizes the accommodating cavity 11 of the heat dissipation housing 1 to place the inductor element, and the side walls and the bottom wall of the heat dissipation housing 1 are provided with cooling grooves for the flow of coolant, so that the heat dissipation housing 1 can simultaneously dissipate heat from the surrounding walls and end faces of the inductor element, thereby increasing the heat dissipation area of ​​the inductor element, enhancing the cooling effect on the inductor element, and ensuring the normal use of the inductor element.

[0030] In this embodiment, the cooling liquid enters the cooling groove through the liquid inlet 12. The cooling groove is distributed in the side plate and the bottom plate of the heat dissipation shell 1. The cooling liquid flows in the cooling groove to the liquid outlet 13 and is discharged. It can effectively reduce the temperature of the side wall and the bottom wall of the heat dissipation shell 1, and then cool the surrounding wall and the end face of the inductor element respectively, which has a good cooling effect.

[0031] In one possible implementation, see Figures 1 to 7 The heat dissipation housing 1 includes an outer shell 2, an inner bottom plate 3 and two inner side plates 4. The outer shell 2 is opened upward, the two inner side plates 4 are connected to the opposite side walls of the outer shell 2 in a one-to-one correspondence, and the inner bottom plate 3 is connected to the inner bottom wall of the outer shell 2;

[0032] The cooling groove includes a side plate cooling groove 5 and a bottom plate cooling groove 6. A first concave cavity 51 is respectively provided on the two opposite inner side walls of the outer shell 2, and the inner side plate 4 and the outer shell 2 enclose the side plate cooling groove 5; a second concave cavity 61 is provided on the inner bottom wall of the outer shell 2, and the inner bottom plate 3 and the outer shell 2 enclose the bottom plate cooling groove 6.

[0033] In this embodiment, the heat dissipation housing 1 is a rectangular component, the accommodating cavity 11 is a rectangular cavity, and the heat dissipation housing 1 is composed of an outer housing 2, an inner bottom plate 3 and an inner side plate 4, which effectively reduces the processing difficulty of the structure and thus reduces the manufacturing cost. The side plates with larger areas among the side walls of the heat dissipation housing 1 are defined as side plates, and the end plates with smaller areas are defined as end plates. The cooling grooves are provided on the side plates and the bottom plate of the heat dissipation housing 1. Multiple inductance elements are arranged at intervals along the length direction of the heat dissipation housing 1, and the end faces of the inductance elements are cooled by the side plates of the heat dissipation housing 1.

[0034] During processing, a first concave cavity 51 is firstly opened on two opposite side walls of the outer shell 2 by using CNC automated machine tools, and then an inner plate 4 for blocking the first concave cavity 51 is arranged on the inner side of the outer shell 2, and the inner plate 4 is welded to the inner wall of the outer shell 2 to achieve blocking of the first concave cavity 51, and then a side plate cooling groove 5 is formed between the outer shell 2 and the inner plate 4.

[0035] Similarly, a second concave cavity 61 is provided on the inner bottom wall of the outer shell 2, and the inner bottom plate 3 is sealed above the second concave cavity 61, and cooperates with the outer shell 2 to form a bottom plate cooling groove 6. The bottom plate cooling groove 6 and the side plate cooling groove 5 are interconnected, so as to facilitate the coolant entering from the liquid inlet 12 to be sent to the liquid outlet 13 for discharge, thereby ensuring that the side and bottom of the heat dissipation housing 1 can form a cooling effect on the inductor element.

[0036] In one possible implementation, see Figures 1 to 7 A plurality of horizontally extending heat transfer ribs 52 are provided in the first concave cavity 51, and a first flow channel 53 for the circulation of the coolant is formed between two adjacent heat transfer ribs 52. A first gap 54 for the circulation of the coolant is provided between the two ends of the heat transfer rib 52 and the two end walls of the first concave cavity 51.

[0037] In this embodiment, heat transfer ribs 52 are provided in the side plate cooling groove 5, which facilitates the side plate cooling groove 5 to be divided into a plurality of first flow channels 53, thereby ensuring the smooth flow of the coolant. The first gaps 54 at both ends of the heat transfer ribs 52 allow the plurality of first flow channels 53 to be interconnected, so that the first flow channels 53 are evenly distributed on the side plate of the heat dissipation housing 1, thereby improving the uniformity of cooling.

[0038] For some examples, see Figures 1 to 7A welding platform 55 connected to the heat transfer rib 52 is provided in the first cavity 51. The outer end surface of the welding platform 55 is connected to the inner plate 4. A plurality of welding platforms 55 are provided at intervals along the direction of the heat transfer rib 52. The provision of the welding platform 55 facilitates the welding connection between the inner plate 4 and the outer shell 2. The inner plate 4 and the outer shell 2 are connected by stir friction welding, which avoids defects such as pores, cracks and slag inclusions caused by other welding methods, so that the cooling tank has good air tightness. The provision of the welding platform 55 can improve the reliability of the welding connection and also improve the compressive strength of the structure.

[0039] In one possible implementation, see Figures 1 to 7 The liquid inlet 12 and the liquid outlet 13 are respectively arranged on the same end plate of the outer shell 2, and the liquid inlet 12 and the liquid outlet 13 are respectively arranged close to the two sides of the outer shell 2. The liquid inlet 12 is connected with one of the side plate cooling grooves 5 through the first confluence groove 16, and the liquid outlet 13 is connected with the other side plate cooling groove 5 through the second confluence groove 17. The side plate cooling groove 5 and the bottom plate cooling groove 6 are connected through the connecting groove 15.

[0040] In this embodiment, the liquid inlet 12 and the liquid outlet 13 are arranged on the same end face of the outer shell 2. The coolant is supplied to the side plate cooling groove 5 on one side of the heat dissipation shell 1 through the liquid inlet 12. Then the coolant enters the side plate cooling groove 5 on the other side through the bottom cooling groove, and is finally discharged through the liquid outlet 13, thereby realizing the effective circulation of the coolant.

[0041] When the liquid inlet 12 supplies coolant to one of the side plate cooling grooves 5, the first confluence groove 16 between the two is used for communication, and the liquid outlet 13 is connected to the side plate cooling groove 5 on the other side through the second confluence groove 17. The two side plate cooling grooves 5 are connected to the bottom cooling groove through the connecting grooves 15 respectively, so that the coolant can flow smoothly inside the heat dissipation shell 1, ensuring a good cooling effect.

[0042] For some examples, see Figures 1 to 7 The liquid inlet 12 is arranged lower than the liquid outlet 13, and the connecting groove 15 is arranged at one end of the outer shell 2 away from the liquid inlet 12. The setting position of the connecting groove 15 can avoid position interference with the first confluence groove 16 and the second confluence groove 17, thereby improving the rationality of the structural layout.

[0043] In one possible implementation, see Figures 1 to 7 A plurality of horizontally extending dividing ribs 62 are provided in the second concave cavity 61, and a second flow channel 63 for the coolant to flow is formed between the dividing ribs 62. Second gaps 64 for the coolant to flow are provided between the two ends of the dividing ribs 62 and the two end walls of the second concave cavity 61, respectively.

[0044] In this embodiment, the partition rib 62 provided in the second cavity 61 is similar in structure to the heat transfer rib 52 inside the side plate cooling groove 5, and can divide the second cavity 61 into a plurality of second flow channels 63. The second gap 64 between the end of the partition rib 62 and the side wall of the second cavity 61 can allow the coolant to communicate with each other among the plurality of different second flow channels 63, thereby ensuring the smoothness of the coolant circulation.

[0045] For some examples, see Figures 1 to 7 The second cavity 61 is also provided with a main rib 65 parallel to the dividing rib 62, and one end of the main rib 65 is connected to the inner cavity wall of the second cavity 61. One end of the main rib 65 close to the liquid inlet 12 is connected to the corresponding inner cavity wall of the second cavity 61. The cooling liquid flowing into the bottom cooling groove from the connecting groove 15 can be effectively extended in the bottom cooling groove by the main rib 65, thereby enhancing the cooling effect on the peripheral wall of the inductor element.

[0046] In one possible implementation, see Figures 1 to 7 A separator 7 protruding upwards and used to separate two adjacent inductance elements is provided on the inner bottom wall of the heat dissipation housing 1, and arc-shaped limiting surfaces 71 for limiting the outer peripheral walls of the inductance elements are provided on both sides of the separator 7.

[0047] In this embodiment, the partition seat 7 provided on the inner bottom wall of the heat dissipation housing 1 can effectively separate two adjacent inductance elements, and the arc-shaped limiting surfaces 71 on both sides of the partition seat 7 can effectively contact the outer peripheral wall of the inductance element, thereby increasing the cooling area of ​​the inductance element. At the same time, the inductance element can be limited to prevent the inductance element from rolling in the accommodating cavity 11, thereby ensuring the cooling effect on the inductance element.

[0048] For some examples, see Figures 1 to 7 Four limit blocks 14 are also provided in the heat dissipation housing 1, and the four limit blocks 14 are arranged one by one at the four corners of the bottom of the accommodating cavity 11. The four limit blocks 14 can limit the positions of the two inductance elements located at both ends of the heat dissipation housing 1, and at the same time facilitate the layout of the first confluence groove 16, the second return groove and the connecting groove 15, so that the side plate cooling groove 5 and the bottom plate cooling groove 6 are effectively connected, which enhances the smoothness of the coolant flow and ensures the effective cooling of the inductance element.

[0049] The above-mentioned inductor element liquid-cooled radiator utilizes the accommodating cavity 11 of the heat dissipation shell 1 to place the inductor element. The side walls and the bottom wall of the heat dissipation shell 1 are provided with cooling grooves for the flow of coolant, so that the heat dissipation shell 1 can simultaneously dissipate heat on the surrounding walls and end faces of the inductor element, thereby increasing the heat dissipation area of ​​the inductor element, enhancing the cooling effect on the inductor element, and ensuring the normal use of the inductor element.
