Description

Technical Field

[0001] This utility model relates to a cooling device, and more particularly to a cooling device for a transceiver. Background Technology

[0002] Currently, most cooling technologies used in transceivers rely on air cooling. However, as transceiver data transmission rates increase, power consumption also rises. For example, current 800G and 1600G transceivers may consume as much as 33W to 40W. As transceivers generate more heat, the entire system requires more powerful cooling equipment, and existing air cooling systems are no longer sufficient to meet the heat dissipation needs of transceivers.

[0003] Therefore, a cooling device is needed to solve the above problems. Utility Model Content

[0074] The following invention provides numerous different embodiments or instances for implementing various features of the provided object. Specific examples of components and arrangements are described below to simplify the invention. These are, of course, merely examples and are not intended to be limiting. Furthermore, element symbols and / or letters may be repeated in various instances of the invention. This repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or configurations discussed.

[0075] To enable readers to clearly understand the interrelationships and orientations of the various components, coordinate axes are marked in the attached diagram, namely the first axis A1, the second axis A2, and the third axis A3.

[0076] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a cooling device CD according to one embodiment of the present invention. Figure 2 This is an exploded view of a cooling device CD according to one embodiment of the present invention.

[0077] In some embodiments, the cooling device CD includes a water-cooled plate 100, comprising a body 110, a top cover 120, a first gasket 130, a floating cover 140, an elastic element 150, a second gasket 160, and a third gasket 170.

[0078] In some embodiments, the body 110, the top cover 120, and the floating cover 140 are made of metal. For water cooling applications, metal materials with high thermal conductivity and excellent corrosion resistance can be used to ensure efficient heat dissipation and long-term stability. Examples of such metal materials include copper.

[0079] In some embodiments, the first washer 130, the second washer 160, and the third washer 170 are made of materials including nitrile rubber (NBR), silicone rubber (SI), fluororubber (VITON or FKM), ethylene propylene diene monomer (EPDM or EPT), polyurethane rubber (PU), or perfluororubber (FFKM).

[0080] In some embodiments, the elastic element 150 comprises rubber, such as the material of the first washer 130, the second washer 160 and the third washer 170 described above.

[0081] In some embodiments, the cooling device CD includes a first connecting element 210 and a second connecting element 220 disposed on opposite sides of the body 110 of the water-cooled plate 100. The first connecting element 210 and the second connecting element 220 are configured to connect to pipelines to provide cooling liquid to the water-cooled plate 100, and can be connected to pipelines in any form.

[0082] Please refer to the accompanying text. Figure 3A , Figure 3A This is a schematic diagram of the body 110. In some embodiments, the body 110 has a surface 111, an annular rib 112 protruding from the surface 111, and a slot 113 penetrating the body 110 from the surface 111. The annular rib 112 forms a liquid-cooled region 114 on the surface 111, and the slot 113 is located in the liquid-cooled region 114. Figure 3A The liquid cooling region 114 has four slots 113, but the present invention is not limited thereto. In practical applications, the dimensions of the body 110 and the liquid cooling region 114 can be adjusted as needed to increase or decrease the number of slots 113.

[0083] Please also refer to Figure 2 and Figure 3A In some embodiments, the top cover 120 covers the surface 111 of the body 110. A first washer 130 is located between the body 110 and the top cover 120 and is disposed along the annular rib 112. An elastic member 150 is located between the floating cover 140 and the top cover 120. A second washer 160 and a third washer 170 are located between the floating cover 140 and the body 110.

[0084] Specifically, a first groove 1110 surrounding the annular rib 112 is provided on the surface 111 of the body 110 to accommodate a first gasket 130. This is done when the water-cooled plate 100 is in an assembled state (e.g., Figure 1 As shown, the liquid cooling area 114 in the upper cover 120 and the body 110 will form a liquid cooling space into which liquid can be placed, and the liquid leakage in the liquid cooling space is prevented by the first gasket 130 disposed on the periphery of the annular rib 112.

[0085] Please refer to the accompanying text. Figure 3B , Figure 3B This is a magnified view of a portion of the main body 110, where the magnified area is... Figure 3A The portion enclosed by the dashed line M1. In some embodiments, the body 110 has an inner edge surface 116 within the slot 113. The surface 111 of the body 110 has a second groove 1112 surrounding the slot 113, configured to accommodate a second washer 160. In some embodiments, a second surface 1131, lower than the surface 111, is formed between the second groove 1112 and the slot 113.

[0086] When the water-cooled plate 100 is in an assembled state (e.g.) Figure 1 As shown, the second gasket 160 is disposed in the second groove 1112, the floating cover plate 140 contacts the second surface 1131 and covers the second gasket 160, and the second gasket 160 prevents liquid leakage. The second surface 1131 is lower than the surface 111 to form a space around the groove 113 where the floating cover plate 140 can be inserted, which facilitates quick positioning during assembly.

[0087] In some embodiments, the surface 111 of the body 110 has water flow holes located on opposite sides within the liquid-cooled region 114, the number of which can be increased or decreased as needed. Figure 3A In the liquid cooling region 114, water flow holes 1151, 1152, 1153, and 1154 are respectively provided on two opposite sides. When the water cooling plate 100 is in the assembled state (e.g. Figure 1 As shown, the liquid in the liquid-cooled space can flow in or out through the drain holes 1151, 1152, 1153 and 1154 respectively. For example, the liquid can flow into the liquid-cooled space through the drain holes 1151 and 1152 and then be discharged through the drain holes 1153 and 1154, or vice versa.

[0088] In some embodiments, the body 110 has drainage holes located on opposite sides. Figure 3A In the main body 110, drain holes 1171, 1172, 1173, and 1174 are respectively provided on opposite sides, which are connected to the corresponding first connecting element 210 and second connecting element 220, so that cooling liquid can flow in or out through the pipes of the first connecting element 210 and the second connecting element 220. The liquid can flow outside the main body 110 and within the liquid cooling area 114 through the interconnected drain holes and water flow holes (for example, water flow hole 1151 is connected to drain hole 1171, and so on). When the water cooling plate 100 is in the assembled state (e.g. Figure 1 As shown), drain holes 1171 to 1174, water flow holes 1151 to 1154, liquid cooling area 114, and top cover 120 together form a water flow space 180 (please refer to...). Figure 5 ).

[0089] Please see Figures 4A to 4D . Figures 4A to 4D These are front view, back view, side view, and another side view of the floating cover 140. Figure 4C and Figure 4D They are in Figure 4A The side view is taken from the perspective of arrows 4C and 4D.

[0090] Please see Figure 4A In some embodiments, the floating cover 140 has a top surface 143 facing the upper cover 120 and a plurality of fins 144 located on the top surface 143. The fins 144 may be arranged at intervals between each other. The arrangement direction of the fins 144 is relative to the liquid flow direction within the liquid-cooled region 114 to facilitate smooth liquid flow. For example, the arrangement direction of the fins 144 may be parallel to the arrangement direction of the water outlets 1151, 1153, or parallel to the arrangement direction of the water outlets 1152, 1154 (see also [reference needed]). Figure 3A ).

[0091] In some embodiments, the floating cover 140 has a platform 146 located on the top surface 143, and a groove 1461 located on the platform 146 and configured to accommodate the elastic member 150. The platform 146 is arranged parallel to the fin 144, and the groove 1461 is similarly parallel to the fin 144. The top surface 143 may have a plurality of platforms 146 arranged at intervals from each other.

[0092] Please see Figure 4B In some embodiments, the floating cover 140 has a body contact surface 141 facing the surface 111. A second gasket 160 is located between the surface 111 and the body contact surface 141. Specifically, when the water-cooled plate 100 is in an assembled state (e.g., Figure 1 As shown), the floating cover 140 contacts the second surface 1131 of the body 110 via the body contact surface 141 and covers the second gasket 160 (please refer to the accompanying document). Figure 2 , Figure 3A and Figure 3B ).

[0093] In some embodiments, the floating cover 140 has an outer edge surface 142 facing the inner edge surface 116 of the body 110 (see also [reference needed]). Figure 2 and Figure 3B The third washer 170 is located between the inner edge surface 116 of the body 110 and the outer edge surface 142 of the floating cover 140. The outer edge surface 142 of the floating cover 140 has a third groove 1420 configured to accommodate the third washer 170. This is when the water-cooled plate 100 is in an assembled state (e.g., Figure 1 As shown, a third gasket 170 can be used to prevent liquid leakage between the floating cover 140 and the body 110.

[0094] Please see Figure 4B and Figure 4C In some embodiments, the floating cover 140 has an element contact surface 145 for contacting a heating element. The element contact surface 145 has a first contact surface 1451 and a second contact surface 1452. The first contact surface 1451 is parallel to the top surface 143, and the second contact surface 1452 is inclined from one side of the first contact surface 1451 toward the top surface 143. In some embodiments, the heating element is a fiber optic transceiver or other elements requiring heat dissipation.

[0095] Please see Figure 4C When installing the heating element, it will be installed from right to left along the element contact surface 145 in the direction of arrow E. Because the element contact surface 145 has an inclined second contact surface 1452, the heating element can be well guided into the installation position, and possible collisions or wear due to sharp edges can be avoided.

[0096] Please refer to the accompanying materials. Figure 2 , Figure 3A and Figure 4A In some embodiments, the elastic element 150 is located between the top surface 143 of the floating cover 140 and the upper cover 120. The elastic element 150 is positioned parallel to the arrangement direction of the drainage holes on opposite sides within the liquid cooling region 114. For example, the elastic element 150 is positioned parallel to the arrangement direction of the drainage holes 1151 and 1153, or parallel to the arrangement direction of the drainage holes 1152 and 1154.

[0097] In some embodiments, the elastic element 150 is arranged in a direction parallel to the arrangement direction of the fins 144. The elastic element 150 and the fins 144 can cooperate with each other to adjust the spacing between them, so as to divide a plurality of equally spaced flow channels on the top surface 143 of the floating cover plate 140, so that the cooling liquid can pass through the floating cover plate 140 evenly.

[0098] Please see Figure 5 , Figure 5 This is a partial cross-sectional view of the water-cooled plate 100 on which the heating element 310 is mounted. The partial cross-section of the water-cooled plate 100 is along... Figure 1 The section is cut along the sectional line B-B'. In some embodiments, the heating element 310 is a transceiver.

[0099] The water-cooled plate 100 has a floating function due to the configuration of the floating cover plate 140, the elastic element 150, the second washer 160 and the third washer 170. When the heating element 310 is installed, it can make proper and good contact with the water-cooled plate 100 to achieve the best heat dissipation effect.

[0100] Specifically, when the heating element 310 is installed onto the water-cooling plate 100, a force is applied to push the floating cover 140 toward the upper cover 120. At this time, the third washer 170 slides on the inner edge surface 116, allowing the floating cover 140 to move slightly upward. Simultaneously, the pressure of the second washer 160 is released, and the elastic member 150 is squeezed. When the heating element 310 is removed from the water-cooling plate 100, the pressure of the elastic member 150 is released, and the elasticity of the elastic member 150 itself applies downward force, causing the floating cover 140 to return to its original position, while simultaneously squeezing the second washer 160.

[0101] Therefore, the floating cover 140, the elastic element 150, the second washer 160, and the third washer 170 together form a floating structure. In this floating structure, the elastic element 150 is configured to provide downward recoil pressure to reset the floating cover 140. The second washer 160 and the third washer 170 are configured to achieve a double-layer leak-proof effect, ensuring that the floating cover 140 remains waterproof and leak-proof while floating up and down. The third washer 170 is further configured to slide on the inner edge surface 116 to allow the floating cover 140 to float up and down relative to the body 110.

[0102] Generally, since both the cooling device and the heating element are made of rigid metal, slight errors in installation or assembly can cause the heating element to have poor and inadequate contact with the cooling device, resulting in a less than expected heat dissipation effect. The cooling device CD of this invention utilizes the aforementioned floating structure of the water-cooled plate 100. During the installation of the heating element 310, the floating cover plate 140 is adjusted to ensure that the element contact surface 145 of the floating cover plate 140 is fully in contact with the heating element 310, thereby optimizing the heat dissipation effect.

[0103] Please see Figure 6 , Figure 6 This is a schematic diagram of a cooling device CD-1 according to another embodiment of the present invention. In some embodiments, the cooling device CD-1 includes a water-cooled plate 100-11, a first connecting element 210-11 and a second connecting element 220-11 connecting opposite sides of the water-cooled plate 100-11, a water-cooled plate 100-12, a first connecting element 210-12 and a second connecting element 220-12 connecting opposite sides of the water-cooled plate 100-12, a first connecting pipe 230 connecting the first connecting element 210-11 and the first connecting element 210-12, and a second connecting pipe 240 connecting the second connecting element 220-11 and the second connecting element 220-12. The water-cooled plates 100-11 and 100-12 have the same structure as the water-cooled plate 100 of the cooling device CD described above. For a detailed structural description, please refer to the above description and... Figures 1 to 5 This will not be elaborated upon here.

[0104] In some embodiments, the drain holes of water-cooled plates 100-11 and 100-12 located on the same side are connected by a first connecting pipe 230, and the drain holes of water-cooled plates 100-11 and 100-12 located on the other side are connected by a second connecting pipe 240, so that the cooling liquid can enter water-cooled plates 100-11 and 100-12 simultaneously for heat dissipation.

[0105] In some embodiments, the first connecting element 210-11, the first connecting element 210-12, and the first connecting pipe 230 may be integrally formed and regarded as a connecting element of the cooling device CD-1. For example, it may be a manifold that connects both water-cooled plate 100-11 and water-cooled plate 100-12, or connected in other forms. The same applies to the second connecting element 220-11, the second connecting element 220-12, and the second connecting pipe 240.

[0106] Please see Figure 7 and Figure 8 , Figure 7 and Figure 8 The illustration shows an embodiment of the cooling device of this invention applied to a network device, such as a network switch. Figure 7 This is a diagram illustrating the network device ID. Figure 8 A partial cross-sectional view of the network device ID. Figure 8 It is along Figure 7 The section line FF′ is used to create a cross section and the local area enclosed by the dashed line M2 is displayed.

[0107] exist Figure 7 In the network device ID, water-cooled plates 100-21 and 100-22 are included, along with a first connecting element 210-21 and a second connecting element 220-21 connected to the water-cooled plates 100-21 and 100-22 on opposite sides, and a communication port 320 for mounting a heat-generating element. In one embodiment, the heat-generating element is an optical transceiver, and the communication port is used to accommodate the optical transceiver.

[0108] In this embodiment, the network device ID has thirty-two communication ports 320 for mounting transceivers, but is not limited thereto. Specifically, sixteen communication ports 320 in the upper row of the network device ID are connected by water-cooling plates 100-21, and sixteen communication ports 320 in the lower row of the network device ID are connected by water-cooling plates 100-22, respectively cooling the thirty-two communication ports 320 arranged vertically. The communication ports 320 correspond to the positions of each slot and floating cover in the water-cooling plates. As mentioned above, the slots and floating covers can be increased or decreased as needed, and therefore the number of communication ports 320 can also be adjusted accordingly. In another embodiment, the network device ID may have sixty-four communication ports 320 for mounting transceivers, but this invention is not limited thereto.

[0109] exist Figure 7 In this design, water-cooled plate 100-21, water-cooled plate 100-22, first connecting element 210-21, and second connecting element 220-21 are integrally formed. Water-cooled plate 100-21 and water-cooled plate 100-22 have the same internal structure as water-cooled plate 100 described above. For detailed structural descriptions, please refer to the above description and... Figures 1 to 5 The connection method of the first connecting element 210-21 and the second connecting element 220-21 is similar to that of the cooling device CD-1 described above, and will not be described in detail here.

[0110] Depend on Figure 8 As can be seen in the partial cross-sectional view, in one embodiment, the connecting element 210-21 has a liquid flow space 350 that can communicate with both the water-cooled plate 100-21 and the water-cooled plate 100-22, allowing cooling liquid to flow to both water-cooled plates 100-21 and 100-22 simultaneously. The upper communication port 320 corresponds to one of the floating cover plates 140-21 of the water-cooled plate 100-21, and the body 110-21, the upper cover 120-21, the floating cover plate 140-21, and the upper communication port 320 form a structure for mounting a heat-generating element (e.g., a transceiver).
