[0034] Referring to Figure 1 As shown in the figure, according to the liquid cooling plate 1000 provided by the embodiment of the application, the liquid cooling plate 1000 comprises a flow divider 100 and a plurality of cooling plate bodies 200, the flow divider 100 comprises a welded fixed upper shell 140 and a lower shell 150, the upper shell 140 and the lower shell 150 cooperate to form a liquid inlet 110 and a liquid outlet 120, and the flow divider 100 is provided with a confluence passage 130 in communication with the liquid inlet 110 and the liquid outlet 120 (i.e., between the upper shell 140 and the lower shell 150).

[0035] A plurality of cold plate bodies 200 are arranged along the extension direction of the confluence channel 130. The cold plate body 200 includes a movable section 210, a curved bending section 220, and a fixed section 230. The two ends of the bending section 220 are connected to the movable section 210 and the fixed section 230, respectively. One side of the fixed section 230 in the thickness direction is provided with a shunt inlet 231 and a shunt outlet 232. The movable section 210 is provided with a shunt channel 211 that communicates with the shunt inlet 231 and the shunt outlet 232. Specifically, the shunt channel 211 is in the shape of a U. The two ends of the U-shaped shunt channel 211 pass through the bending section 220 and communicate with the shunt inlet 231 and the shunt outlet 232, respectively. The shunt inlet 231 and the shunt outlet 232 both communicate with the confluence channel 130. The fixed section 230 is welded to one side of the shunt device 100 in the thickness direction.

[0036] The bending section 220 includes a first bending part 221 that can bend upwards relative to the fixed section 230 and a second bending part 222 that can bend downwards relative to the fixed section 230. The first bending part 221 and the second bending part 222 are smoothly connected. Optionally, the first bending part 221 is in the shape of an arc with the opening facing upwards, and the second bending part 222 is in the shape of an arc with the opening facing downwards. The first bending part 221 and the second bending part 222 are equal in size and are formed by a bending process.

[0037] It can be understood that when the liquid cooling plate 1000 is installed, the movable section 210 is attached to the optical module to be cooled. The refrigerant enters the liquid cooling plate 1000 through the liquid inlet 110 of the shunt device 100 and flows through the confluence channel 130 and the shunt channel 211 in sequence, thereby cooling the optical module.

[0038] By providing the bending section 220, the first bending part 221 of the bending section 220 can adapt to the upward bending deformation of the movable section 210 when the optical module is inserted for installation. The second bending part 222 of the bending section 220 can adapt to the downward bending deformation of the movable section 210 when the optical module is pulled out. This avoids hard bending deformation of the liquid cooling plate 1000. By eliminating the elastic components between the liquid cooling plate 1000 and the optical module, the liquid cooling plate 1000 can be attached to the optical module for cooling and can adapt to the insertion and removal of the optical module. This effectively improves the cooling efficiency.

[0039] It should be noted that the shunt passages 211 in the plurality of cold plate bodies 200 can be arranged in parallel, at this time, the confluence passages 130 include the liquid inlet passages 131 and the liquid outlet passages 132 which are parallel to each other, the liquid inlet passages 131 are in communication with the liquid inlet ports 110, the liquid outlet passages 132 are in communication with the liquid outlet ports 120, the liquid inlet passages 131 and the liquid outlet passages 132 are arranged in the width direction of the flow divider 100, the shunt inlets 231 of the plurality of confluence passages 130 are in communication with the liquid inlet passages 131 respectively, and the shunt outlets 232 of the plurality of confluence passages 130 are in communication with the liquid outlet passages 132 respectively, so as to realize the rapid flow-through refrigeration of the liquid cooling plate 1000. The shunt passages 211 in the plurality of cold plate bodies 200 can also be arranged in series, at this time, the shunt inlets 231 and the shunt outlets 232 of the plurality of confluence passages 130 are in communication with the same confluence passage 130, so as to prolong the contact time of the refrigerant and the optical module and ensure the refrigeration efficiency.

[0040] It should be further supplemented that the cold plate body 200 can be formed by welding the sheet-shaped upper cover body 250 and the sheet-shaped lower cover body 260, the shunt passage 211 is formed between the upper cover body 250 and the lower cover body 260, the shunt inlet 231 and the shunt outlet 232 are arranged on the side of the upper cover body 250 facing the flow divider 100 (when the cold plate body 200 is welded to the bottom surface of the flow divider 100), or arranged on the side of the lower cover body 260 facing the flow divider 100 (when the cold plate body 200 is welded to the top surface of the flow divider 100). By arranging the sheet-shaped upper cover body 250 and the sheet-shaped lower cover body 260, the height dimension of the cold plate body 200 can be greatly reduced, an ultra-thin cold plate body 200 (the height is less than or equal to 1.2 cm) can be made, the overall volume of the liquid cooling plate 1000 is reduced, and the welding flexibility is good and the thermal source of the optical module is well adhered.

[0041] Further, since the upper cover body 250 and the lower cover body 260 are thin, a support column 270 is arranged between the upper cover body 250 and the lower cover body 260, the support column 270 is distributed in the shunt passage 211, one end of the support column 270 is connected with one of the upper cover body 250 or the lower cover body 260, and the other end is abutted with the other one of the upper cover body 250 or the lower cover body 260, the support column 270 can enhance the pressure resistance of the cold plate body 200 and improve the structural stability of the cold plate body 200.

[0042] Optionally, the upper shell 140, the lower shell 150, the upper cover body 250 and the lower cover body 260 can be integrally welded by brazing process, which reduces the influence of multiple welding on the function and cost of the finished product of the liquid cooling plate 1000. The upper cover body 250 and the lower cover body 260 can also be fixed separately by diffusion welding and the like, so as to improve the structural strength of the cold plate body 200. The upper shell 140, the lower shell 150, the upper cover body 250 and the lower cover body 260 are all made of copper material for welding, which reduces the risk of leakage and improves the product reliability.

[0043] Further, the connection between the active section 210 and the bending section 220 and the connection between the fixed section 230 and the bending section 220 are both through a round corner transition.

[0044] By setting the round corner, the round corner structure can effectively disperse the stress concentration phenomenon of the bending section 220 when deforming under stress, avoiding cracks or fractures at the connection between the bending section 220 and the active section 210 or the fixed section 230. And the round corner structure can guide the bending section 220 to preferentially undergo controllable elastic deformation when deforming under stress, avoiding hard bending of the bending section 220 at the connection with the active section 210 or the fixed section 230, and improving the structural rationality of the cold plate main body 200.

[0045] Continuing to refer to Figure 1 As shown in FIG. 10, one side of the active section 210 in the thickness direction is connected with a rigid piece 300, the width of the rigid piece 300 is equal to the width of the active section 210, and the rigid piece 300 covers at least part of the active section 210. Optionally, the rigid piece 300 can be made of the same copper material as the cold plate main body 200, facilitating welding and fixation of the rigid piece 300, and the rigid piece 300 can also be selected from other alloy pieces with a higher Young's modulus, which will not be described here.

[0046] By setting the rigid piece 300, when the liquid cooling plate 1000 is installed, the side of the cold plate main body 200 away from the optical module is usually abutted with an elastic component, thereby providing pressure to the cold plate main body 200 to press the optical module, and the rigid piece 300 can be abutted with the elastic component to disperse the stress of the elastic component, avoiding damage or bruising of the cold plate main body 200 by the elastic component, or avoiding scratches on the cold plate main body 200 during installation and use of the liquid cooling plate 1000, further prolonging the service life of the cold plate main body 200.

[0047] Further, the liquid inlet 110 and the liquid outlet 120 are both connected with an interface piece 400. Optionally, the interface piece 400 can be a copper pipe, a joint or other component welded and fixed with the flow divider 100, which will not be described here.

[0048] By setting the interface piece 400, the user can conveniently connect the liquid cooling plate 1000 to a thermal management system later, improving the integration and disassembly convenience of the liquid cooling plate 1000.

[0049] Referring to Figures 1 to 3 As shown in FIG. 11, the present embodiment also provides an optical module liquid cooling structure 2000, which includes a circuit board 500, a support piece 600, a fixed cage 700 and the above-mentioned liquid cooling plate 1000. The support piece 600 and the circuit board 500 are respectively located on both sides of the fixed cage 700, the circuit board 500 is detachably connected with the fixed cage 700, the support piece 600 is provided with a plurality of elastic pieces 610, the fixed cage 700 is provided with a plurality of sockets 710, and the sockets are used to install optical modules 720, in other words, the optical modules 720 are inserted and matched with the sockets.

[0050] The elastic sheet 610, the optical module 720, and the socket 710 are arranged one by one corresponding to the cold plate body 200. The optical module 720 is plugged into the socket 710 and is electrically connected to the circuit board 500. The movable section 210 of the cold plate body 200 is located between the elastic sheet 610 and the fixed cage 700. The top wall of the socket 710 is provided with a through hole 711. The side of the movable section 210 facing the fixed cage 700 (i.e., the side of the movable section 210 away from the rigid member 300) is connected with a heat conduction member 240. The rigid member 300 on the movable section 210 is abutted by the elastic sheet 610 so that the heat conduction member 240 is arranged in the through hole 711 and abuts against the optical module 720. At this time, the support member 600, the elastic sheet 610, the cold plate body 200 (the rigid member 300, the movable section 210, and the heat conduction member 240), the optical module 720, and the circuit board 500 are arranged in the vertical direction from top to bottom in sequence. Optionally, the heat conduction member 240 can be a copper plate member welded to the movable section 210. The width of the heat conduction member 240 is equal to the width of the movable section 210, and the heat conduction member 240 covers at least part of the movable section 210.

[0051] It can be understood that when the optical module 720 is inserted into the socket, the optical module 720 lifts the movable section 210 of the cold plate body 200. The first bending part 221 of the bending section 220 of the cold plate body 200 bends upward to absorb the upward deformation of the movable section 210. The elastic sheet 610 abuts against the cold plate body 200 so that the liquid cooling plate 1000 closely abuts against the optical module 720 inserted into the socket, ensuring stable installation of the optical module 720. When the optical module 720 is pulled out of the socket, the movable section 210 of the cold plate body 200 moves downward under the action of the elastic sheet 610. The second bending part 222 of the bending section 220 of the cold plate body 200 bends downward to absorb the downward deformation of the movable section 210, avoiding fatigue failure of the cold plate body 200.

[0052] The liquid cooling plate 1000 directly abuts against the optical module 720 under the action of the elastic sheet 610, eliminating the complex elastic components between the liquid cooling plate 1000 and the optical module 720 in the traditional scheme, simplifying the optical module liquid cooling structure 2000, reducing the height dimension of the optical module liquid cooling structure 2000, and thereby reducing the overall volume. Moreover, the movable section 210 of the liquid cooling plate 1000 abutting against the optical module 720 can swing up and down, without affecting the service life of the liquid cooling plate 1000, while ensuring stable installation of the optical module 720 and good heat dissipation performance. In addition, since the height dimension of the optical module liquid cooling structure 2000 of the embodiment is small, the optical module liquid cooling structure 2000 can be matched with other heat dissipation components in actual use, such as an ultra-thin uniform temperature plate or an ultra-thin heat pipe, to achieve the purpose of solving higher power.

[0053] Further, the heat conduction piece 240 is provided with a guide portion 241 away from one end of the bending section 220. The guide portion 241 is a round corner structure or a chamfer structure provided on the edge of the heat conduction piece 240. The guide portion 241 is used to guide the light module 720 to enter below the heat conduction piece 240.

[0054] By providing the guide portion 241, the guide portion 241 can avoid the collision and extrusion between the light module 720 and the heat conduction piece 240, affect the installation of the light module 720, and even damage the light module 720, effectively improve the convenience of dismounting the light module 720.

[0055] Referring to Figure 3 As shown in the figure, it can be understood that the elastic sheet 610 is provided with a plurality of pressing portions 611. The plurality of pressing portions 611 are arranged at intervals along the length direction of the elastic sheet 610 and are all in abutment with the rigid piece 300 on the movable section 210. The longitudinal sectional shape of the pressing portion 611 is a trapezoid with the upper part larger and the lower part smaller.

[0056] By providing the plurality of pressing portions 611, the plurality of pressing portions 611 cooperate to provide a certain pressing force while avoiding the pressing force being too concentrated to injure the cold plate body 200 or cause the light module 720 to be unstable during installation, effectively improving the contact stability of the elastic sheet 610.

[0057] Further, the side of the supporting piece 600 facing the elastic sheet 610 is provided with a plurality of reinforcing portions 620. The reinforcing portions 620 and the pressing portions 611 are one-to-one corresponding. The reinforcing portions 620 are protrudingly arranged towards the pressing portions 611.

[0058] By providing the reinforcing portions 620, the reinforcing portions 620 can improve the structural strength of the supporting piece 600 near the contact position with the elastic sheet 610, so that the supporting piece 600 can bear greater feedback pressure of the elastic sheet 610 on the pressing plate. In addition, the reinforcing portions 620 guide the elastic force to be concentrated on the central region of the pressing portion 611, so that the elastic sheet 610 is more likely to be compressed and deformed as a whole, thereby providing greater elastic force and improving the installation stability of the light module 720.

[0059] Still further, the supporting piece 600 and the elastic sheet 610 are welded and fixed.

[0060] Welding and fixing the supporting piece 600 and the elastic sheet 610 can avoid the elastic sheet 610 from being displaced and deflected during installation and use, effectively improving the installation stability of the elastic sheet 610.

[0061] It can be understood that the side of the heat conduction piece 240 facing the light module 720 is provided with a heat conduction material layer. Optionally, the heat conduction material layer can be a heat conduction paste coated on the surface of the heat conduction piece 240, or a silicon grease or other heat conduction material bonded to the surface of the heat conduction piece 240, which will not be described here.

[0062] By setting the heat conduction material layer, the heat conduction material layer and the heat conduction piece 240 cooperate, heat generated by the optical module 720 can be quickly conducted to the cold plate main body 200, the heat exchange efficiency between the liquid cooling plate 1000 and the optical module 720 is improved, and the refrigeration performance of the liquid cooling plate 1000 is further enhanced.

[0063] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is not necessary and impossible to enumerate all the embodiments.
