DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0032] Next, the enhanced liquid cooling radiator according to the embodiment of the present utility model is described.

[0033] like Figures 1 to 4 As shown, the enhanced liquid cooling radiator of the embodiment of the utility model includes: a first substrate 200 and a second substrate 100.

[0034] First, the first substrate 200 is described. A groove is formed on one surface of the first substrate 200, and a liquid inlet hole 231 and a liquid outlet hole 232 are formed at the bottom of the groove and penetrate the first substrate 200 and are arranged at intervals. Two groups of reinforcing ribs 240 are formed at the bottom of the groove, and the two groups of reinforcing ribs 240 correspond to the liquid inlet holes 231 and the liquid outlet holes 232 one by one, respectively, and each group of reinforcing ribs 240 includes a plurality of reinforcing ribs 240 arranged at intervals in the circumferential direction around the liquid inlet hole 231 or the liquid outlet hole 232.

[0035] The coolant flows into the groove from the liquid inlet hole 231 and flows out of the groove from the liquid outlet hole 232, and the coolant can continuously dissipate heat for the first substrate 200. Two groups of reinforcing ribs 240 are spaced apart in the circumference of the liquid inlet hole 231 and the circumference of the liquid outlet hole 232, respectively. The reinforcing ribs 240 can protect the liquid inlet hole 231 and the liquid outlet hole 232, improve the strength of the liquid inlet hole 231 and the liquid outlet hole 232, avoid damage to the liquid inlet hole 231 and the liquid outlet hole 232, and improve the life of the first substrate 200. The liquid inlet hole 231 and the liquid outlet hole 232 are usually connected to the external pipeline through the liquid inlet connector and the liquid outlet connector. During the connection process between the liquid inlet hole 231 and the liquid inlet connector, and the connection process between the liquid outlet hole 232 and the liquid outlet connector, the liquid inlet hole and the liquid outlet hole are easily damaged, causing leakage from the liquid inlet hole and the liquid outlet hole. The strength of the liquid inlet hole 231 and the liquid outlet hole 232 is increased by the reinforcing rib 240 , thereby increasing the strength of the radiator and preventing liquid leakage.

[0036] Next, the second substrate 100 is described. The second substrate 100 is connected to the first substrate 200, and includes a first surface and a second surface opposite to each other. The first surface of the second substrate 100 covers the groove, and the second surface of the second substrate 100 is used to connect to an object to be cooled.

[0037] The second substrate 100 is connected to the first substrate 200, and the first surface of the second substrate 100 covers the groove of the first substrate 200, thereby forming a chamber capable of containing cooling liquid. An installation area is formed on the second surface of the second substrate 100, and the installation area is used to connect an object to be cooled, so as to cool the object to be cooled.

[0038] In the above-mentioned enhanced liquid-cooled radiator, the first substrate 200 and the second substrate 100 are connected, so that the groove of the first substrate 200 and the first surface of the second substrate 100 are combined to form a chamber, and the cooling liquid enters the chamber through the liquid inlet hole 231 of the first substrate 200, and flows out of the chamber through the liquid outlet hole 232 of the first substrate 200. A group of reinforcing ribs 240 are respectively arranged on the liquid inlet hole 231 and the liquid outlet hole 232, and each group of reinforcing ribs 240 includes a plurality of reinforcing ribs 240 arranged circumferentially around the liquid inlet hole 231 or the liquid outlet hole 232. The reinforcing ribs 240 can improve the strength of the liquid inlet hole 231 and the liquid outlet hole 232, avoid damage to the liquid inlet hole 231 and the liquid outlet hole 232, and improve the life of the enhanced liquid-cooled radiator.

[0039] In some embodiments of the present invention, the groove includes a main groove 221, a liquid inlet groove 222 and a liquid outlet groove 223. The main groove 221 is located in the middle of the groove, and its bottom is formed in a circular, elliptical, rectangular or polygonal shape. The liquid inlet groove 222 and the liquid outlet groove 223 are respectively connected to both sides of the main groove 221, the liquid inlet hole 231 is located at the bottom of the liquid inlet groove 222, and the liquid outlet hole 232 is located at the bottom of the liquid outlet groove 223.

[0040] like Figure 3 As shown, the main body groove 221 corresponds to the installation area of ​​the second substrate 100 (the area for connecting the object to be cooled), and the liquid inlet hole 231 and the liquid outlet hole 232 are arranged on both sides of the main body groove 221 to prevent the inlet and outlet of the coolant from affecting the cooling of the object to be cooled. The coolant can easily enter and flow out of the main body groove 221 through the liquid inlet groove 222 and the liquid outlet groove 222.

[0041] Furthermore, the bottom of the main body groove 221 is formed into a rectangular shape, and the liquid inlet groove 222 and the liquid outlet groove 223 are respectively arranged on both sides of the main body groove 221 in the width direction.

[0042] like Figure 3 As shown, the main body groove 221 with a rectangular bottom can accommodate more cooling liquid. The liquid inlet groove 222 and the liquid outlet groove 223 are respectively arranged on both sides of the width direction of the main body groove 221, which can make the flow of the cooling liquid smoother.

[0043] Furthermore, the edges of the liquid inlet groove 222 and the liquid outlet groove 223 are both formed as arcs, the openings of the arcs face the main groove 221 , and each group of reinforcing ribs 240 connects the circumferential side of the liquid inlet hole 231 or the liquid outlet hole 232 facing the main groove 221 .

[0044] like Figure 3As shown, the liquid inlet groove 222 and the liquid outlet groove 223 are formed with arc edges, so that the coolant can flow smoothly from the liquid inlet groove 222 into the main body groove 221, and the coolant can flow smoothly from the main body groove 221 into the liquid outlet groove 223, reducing turbulence.

[0045] Moreover, the reinforcing rib 240 is arranged on one side of the circumference of the liquid inlet hole 231 or the liquid outlet hole 232 facing the main groove 221, and the other side is protected by the side wall of the liquid inlet groove 222 or the liquid outlet groove 223, which can save the reinforcing rib 240 and has no effect on the improvement of the strength of the liquid hole and the liquid outlet hole 232.

[0046] Furthermore, the reinforcing rib 240 is formed in a strip shape, and a first end thereof is connected to the circumference of the liquid inlet hole 231 or the liquid outlet hole 232 , and a second end thereof faces the main body groove 221 .

[0047] like Figure 3 Three strip-shaped reinforcing ribs 240 are distributed around the liquid inlet 231, and three strip-shaped reinforcing ribs 240 are distributed around the liquid outlet 232. The strip-shaped reinforcing ribs 240 have less obstruction to the coolant, reducing flow resistance.

[0048] In some embodiments of the present invention, the enhanced liquid cooling radiator further includes a first solder layer 310. The first solder layer 310 is disposed between the first substrate 200 and the first surface of the second substrate 100.

[0049] like Figure 2 As shown, the first surfaces of the first substrate 200 and the second substrate 100 are connected by soldering via the first solder layer 310 , so that the connection between the first substrate 200 and the second substrate 100 is relatively stable.

[0050] In some embodiments of the present invention, a plurality of pin fins 120 accommodated in the grooves are formed on the first surface of the second substrate 100 .

[0051] like Figure 2 and Figure 4 As shown, a plurality of pin fins 120 are formed on the first surface of the second substrate 100 . The pin fins 120 are inserted into the grooves and can contact the coolant in the grooves, thereby increasing the heat exchange area.

[0052] Furthermore, the enhanced liquid cooling radiator further includes a second solder layer 320. The second solder layer 320 is disposed between the pin fins and the bottom of the groove.

[0053] The second solder layer 320 can ensure that the pin fin is tightly connected to the groove of the first substrate.

[0054] Furthermore, the end surface of the pin fin 120 is formed in a rhombus shape, and the plurality of pin fins 120 are arranged in a plurality of rows and columns.

[0055] like Figure 4 As shown, multiple rows and columns of pin fins 120 can further increase the heat exchange area and improve the heat dissipation efficiency of the object to be cooled.

[0056] The end face of the pin fin 120 is diamond-shaped and can be formed by cutting to form a narrower gap, thereby increasing the density of the pin fin 120, further improving the heat exchange area, and reducing flow resistance.

[0057] In some embodiments of the present invention, at least two first positioning holes 210 spaced apart are formed at the edge of the first substrate 200, and at least two second positioning holes 110 corresponding to the first positioning holes 210 and penetrating the upper and lower surfaces thereof are formed at the edge of the second substrate 100.

[0058] The positioning pin can pass through the second positioning hole 110 and enter the first positioning hole 210, so that the first substrate 200 and the second substrate 100 are aligned, and the first substrate 200 and the second substrate 100 are offset.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
