Description

Technical Field

[0001] The present invention relates to the technical field of optical module heat dissipation, and in particular to a liquid cooling heat dissipation structure. Background Art

[0002] As the power consumption and heat flux density of electronic devices gradually increase, heat dissipation has become a key issue restricting the development of electronic equipment. When the operating temperature exceeds a certain range, the performance of electronic devices decreases as the junction temperature increases, and the failure rate is exponentially related to its junction temperature. Overheating significantly affects its service life; and temperature uniformity affects the stability and failure probability of the entire device. Therefore, it is particularly important to control the uniformity of the junction temperature of electronic devices and the surface temperature of the chip. The internal power consumption of optical modules is mainly concentrated on individual small-sized chips. The local heat flux density near these heat sources is usually high, which is easy to form a heat dissipation bottleneck. The cold plate liquid cooling technology in the prior art is an indirect liquid cooling heat dissipation technology with the advantages of high heat dissipation efficiency, small space occupation, and convenient operation and maintenance.

[0003] In the process of implementing this application, the inventors found that there are at least the following problems in the prior art: On the one hand, the number of single-layer optical modules arranged in the switch device is more than one. Affected by manufacturing tolerances, the conventional integrated cold plate solution cannot ensure that each optical module of the access system can fully contact and dissipate heat with the cold plate structure, resulting in poor heat dissipation of the optical module. On the other hand, the use of elastic interface materials and floating components that can absorb tolerances will bring about a longer heat transfer path, which will lead to an increase in the surface temperature of the heat source to a certain extent. Therefore, a liquid cooling heat dissipation structure is proposed to improve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a liquid cooling heat dissipation structure to improve the technical problem of poor heat dissipation effect of an optical module.

DETAILED DESCRIPTION

[0028] 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.

[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figure 1 and Figure 2 As shown, in order to achieve the above purpose, the present invention provides a liquid cooling structure, including: a bracket 1 and a cold plate structure 2 arranged on one side of the assembly. Preferably, the bracket 1 is formed in one piece by sheet metal processing, and the assembly (not shown in the figure) is used to install the optical module (not shown in the figure). Preferably, the assembly is specifically a squirrel cage, and the optical module can be connected to the system after being inserted into the assembly. The assembly and the optical module are relatively mature existing technologies in the prior art, so they will not be described in detail.

[0031] A plurality of groups of elastic structures 4 are arranged in an array on the surface of the bracket 1, and each group of elastic structures 4 is connected to a cold plate structure 2. The bottom surface of the cold plate structure 2 is parallel to the surface of the bracket 1. Each cold plate structure 2 corresponds to an assembly part. When the optical module is not inserted into the assembly part, the cold plate structure 2 can enter the assembly part. When the optical module is inserted into the assembly part and connected to the system, the surface of the cold plate structure 2 can fit with the surface of the optical module. The cold plate structure 2 automatically adjusts the floating amplitude according to the position of the optical module, so that the surface of the cold plate structure 2 is always tightly fitted with the surface of the optical module, ensuring that each optical module connected to the system can fully contact the cold plate structure 2.

[0032] like Figure 3As shown, a heat exchange channel 3 is arranged inside the cold plate structure 2, and the heat exchange channel 3 is used for circulating a heat exchange medium to absorb the heat of the cold plate structure 2. Specifically, when the surface of the cold plate structure 2 is in contact with the surface of the optical module, the heat generated by the optical module is transferred to the cold plate structure 2, and the cold plate structure 2 further transfers its own heat to the heat exchange medium, and the heat exchange medium takes away the heat on the cold plate structure 2, thereby achieving the purpose of continuously absorbing the heat of the optical module. In addition, the floating of the cold plate structure 2 itself is used to replace additional floating components, which can further shorten the heat transfer path and effectively improve the heat dissipation efficiency of the optical module.

[0033] The heat exchange medium is a liquid medium, preferably, heat transfer oil is used as the heat exchange medium to reduce the impact of heat exchange medium leakage on the optical module access system. Of course, water can also be selected as the heat exchange medium, the purpose of which is to absorb and take away the heat on the cold plate structure 2 when the heat exchange medium circulates in the heat exchange channel 3.

[0034] When in use, after the optical modules are inserted into the assembly parts in turn and connected to the system, the elastic structure 4 is compressed by the corresponding optical modules to a certain extent, and the cold plate structure 2 automatically adjusts the floating amplitude according to the position of the optical module, so that the surface of the cold plate structure 2 is tightly fitted with the surface of the optical module, thereby ensuring that each optical module connected to the system can be fully in contact with the cold plate structure 2, and the heat generated by the optical module is transferred to the cold plate structure 2, and the cold plate structure 2 further transfers its own heat to the heat exchange medium circulating in the heat exchange channel 3, and the heat exchange medium takes away the heat on the cold plate structure 2, and the cold plate structure 2 can continuously and fully absorb the heat of the optical module to ensure the heat dissipation effect of the optical module.

[0035] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the cold plate structure 2 includes: a base plate 201, a cover plate 202 is snap-connected to the base plate 201, specifically, a step groove is provided on the bottom surface of the cover plate 202, and the outer peripheral side surface of the cover plate 202 can fit the inner peripheral side surface of the step groove, so that the base plate 201 and the cover plate 202 are sealed and connected, and then the heat exchange channel 3 is formed by combining the cover plate 202 and the base plate 201, and the length direction of the heat exchange channel 3 extends along the length direction of the cover plate 202. In addition, a partition plate 206 is provided on the bottom surface of the cover plate 202. The partition plate 206 is in a strip shape as a whole and is located in the middle part of the heat exchange channel 3. The partition plate 206 extends along the length direction of the heat exchange channel 3. The partition plate 206 divides the heat exchange channel 3 into a U shape. Furthermore, the liquid inlet and the liquid outlet of the heat exchange channel 3 are both located on the same end surface of the cover plate 202. The heat exchange medium enters the heat exchange channel 3 through the liquid inlet and is discharged from the liquid outlet along the U-shaped heat exchange channel 3. The heat exchange medium is in full contact with the surface of each position of the heat exchange channel 3 to absorb the heat on the cold plate structure 2.

[0036] It should be noted that a plurality of heat conducting plates 203 are arrayed in the heat exchange channel 3, and the heat conducting plates 203 are integrally arranged on the top surface of the inner side of the cover plate 202, and the bottom surface of the heat conducting plates 203 is in contact with the top surface of the bottom plate 201. The arrangement of the heat conducting plates 203 can increase the contact area between the heat exchange channel 3 and the heat exchange medium, thereby improving the heat dissipation efficiency of the cold plate structure 2 and ensuring the heat dissipation effect of the optical module. Furthermore, the heat conducting plates 203 are consistent with the extension direction of the heat exchange channel 3 to ensure that the heat exchange medium flows smoothly in the heat exchange channel 3, and at the same time, the two sides of the heat conducting plates 203 can fully contact the heat exchange medium when the heat exchange medium flows, further improving the heat dissipation efficiency of the cold plate structure 2 and improving the heat dissipation effect on the optical module.

[0037] In addition, a sealing groove 204 is provided on the top surface of the bottom plate 201, and a sealing protrusion 205 is provided on the bottom surface of the partition plate 206, and the sealing protrusion 205 is snap-connected to the sealing groove 204, wherein the sealing groove 204 and the sealing protrusion 205 are both arranged in an annular closed shape, and the sealing protrusion 205 is snap-connected to the sealing groove 204, so that the two ends of the heat exchange channel 3 can be completely separated, ensuring that the heat exchange medium always flows along the U-shaped route, so that the heat exchange medium forms a stable flow path, and the heat exchange medium can fully contact the inner side surface of the heat exchange channel 3 when flowing in the heat exchange channel 3, further ensuring the heat transfer effect between the heat exchange medium and the cold plate structure 2.

[0038] In one embodiment of the present invention, ears 5 are provided on both sides of the cover plate 202. Specifically, two ears 5 are symmetrically provided on both sides of each cover plate 202. Each ear 5 is connected to the top surface of the bracket 1 through an elastic structure 4. The ears 5 on two adjacent cover plates 202 are staggered to reduce the distance between two adjacent cold plate structures 2 so that the two adjacent cold plate structures can accurately fit the optical module in each assembly.

[0039] like Figure 5 As shown, at the same time, a plurality of assembly holes 101 are arranged in an array on the surface of the bracket 1, and the assembly holes 101 are used to penetrate the cold plate structure 2. A group of elastic structures 4 are provided on the circumferential outer side of each assembly hole 101, and the elastic structure 4 is perpendicular to the surface of the bracket 1. The cold plate structure 2 can reciprocate in the assembly hole 101 along the length direction of the elastic structure 4. On the one hand, it can reduce the height of the cold plate structure 2 protruding from the surface of the bracket 1 and reduce the thickness of the overall liquid cooling structure. On the other hand, it can increase the maximum amplitude of the up and down floating of the cold plate structure 2 relative to the bracket 1, that is, maximize the up and down floating space of the cold plate structure 2 relative to the assembly.

[0040] In addition, bending portions 102 are provided at the edge positions of the bracket 1 and at the edge positions of the assembly holes 101 on the bracket 1. The bending portions 102 are integrally formed with the bracket 1. The setting of the bending portions 102 can provide a certain degree of surrounding protection for the cold plate structure and can also improve the structural strength of the overall bracket 1.

[0041] like Figure 4 As shown, in one embodiment of the present invention, the elastic structure 4 includes: a limit screw 401, the limit screw 401 is penetrated by the hanging ear 5, and the top surface of the hanging ear 5 is provided with a through hole, the head of the limit screw 401 is slidably connected to the through hole, and a support spring 402 is sleeved on the circumferential outer side of the limit screw 401, the lower end of the support spring 402 abuts the bracket 1, and the upper end of the support spring 402 abuts the hanging ear 5. During installation, the limit screw 401 is first inserted into the through hole from the top surface of the hanging ear 5, and then the support spring 402 is sleeved on the limit screw 401 from the bottom of the limit screw 401, and the limit screw 401 is screwed so that the bottom thread of the limit screw 401 is connected to the top surface of the bracket 1. At this time, the lower end of the support spring 402 abuts the top surface of the bracket 1, and the upper end of the support spring 402 abuts the bottom surface of the hanging ear 5, and the cold plate structure is lifted up as a whole by the support spring 402 sleeved on each limit screw 401.

[0042] It should be noted that the specifications and dimensions of the limit screws 401 in the same group of elastic structures 4 are the same, and the length of each limit screw 401 threadedly connected with the bracket 1 is consistent, so that the telescopic strokes of the support springs 402 on both sides of the same cold plate structure 2 are the same, so as to ensure that when the same cold plate structure 2 is supported by the optical module, the forces at each position where the cold plate structure 2 contacts the surface of the optical module are the same, thereby ensuring that the surface of the cold plate structure 2 is in full contact with the optical module, and improving the heat transfer effect between the cold plate structure 2 and the optical module. In addition, the distances from the several hanging ears 5 on the same cover plate 202 to the surface of the bracket 1 are the same, further ensuring that the telescopic strokes of the support springs 402 on both sides of the same cold plate structure 2 are the same, so that the surface of the cold plate structure 2 is in full contact with the optical module, and improving the heat transfer effect between the cold plate structure 2 and the optical module.

[0043] like Figure 6As shown, in one embodiment of the present invention, a water divider 6 is provided on one side of the bracket 1, and a water inlet chamber 601 and a drainage chamber 602 are provided in the water divider 6, the water inlet chamber 601 is located at the upper part of the water divider 6, and the drainage chamber 602 is located at the lower part of the water divider 6, and a plurality of water exchange holes 603 are arranged in an array on the side of the water divider 6, each water exchange hole 603 is respectively connected to the water inlet chamber 601 or the drainage chamber 602, and each water exchange hole 603 is respectively connected to the liquid inlet of the heat exchange channel 3 and the liquid outlet of the heat exchange channel 3 through a hose assembly, that is, the water inlet chamber 601 and the drainage chamber 602 are respectively connected to the liquid inlet of the heat exchange channel 3 and the liquid outlet of the heat exchange channel 3 through a hose assembly. In addition, the two ends of the water divider 6 are respectively connected to the water inlet pipe (not shown in the figure) and the water outlet pipe (not shown in the figure) through the first pagoda head 7. Specifically, the left end of the water divider 6 is connected to the water inlet pipe through the first pagoda head 7, and the right end of the water divider 6 is connected to the water outlet pipe through the first pagoda head 7. The water inlet pipe is connected to the water inlet chamber 601, and the water outlet pipe is connected to the water outlet chamber. The heat exchange medium enters the water inlet chamber 601 through the water inlet pipe, and the heat exchange medium in the water inlet chamber 601 enters the heat exchange channels 3 in each cold plate structure 2 respectively. The heat exchange medium moves from the liquid inlet of the heat exchange channel 3 to the liquid outlet of the heat exchange channel 3 and then enters the drainage chamber 602. The heat exchange medium in the drainage chamber 602 is discharged through the water outlet pipe.

[0044] like Figure 7 As shown, the hose assembly includes: a hose 8, preferably, the hose 8 is a PTFE tube, and a pagoda head cover 9 is respectively sleeved on the circumferential outer side of the two ends of the hose 8, and the pagoda head cover 9 can slide along the axial direction of the hose 8. It should be noted that a second pagoda head 10 is embedded at the position of the water exchange hole 603, the liquid inlet position of the heat exchange channel 3, and the liquid outlet position of the heat exchange channel 3. After the two ends of the hose 8 are respectively sleeved on the second pagoda head 10, the two pagoda head covers 9 are respectively sleeved on the corresponding second pagoda heads 10. When the cold plate structure 2 floats, the hose 8 will be caused to have a certain longitudinal bending. The pagoda head cover 9 cooperates with the second pagoda head 10 to further lock the connection strength between the hose 8 and the second pagoda head 10, prevent the hose 8 from leaking when it is longitudinally bent, improve the reliability of the hose 8 connection, thereby protecting the optical module.

[0045] It should be further explained that the inner diameter of the heat exchange medium when flowing through the second pagoda head 10 is reduced by the second pagoda head 10, thereby improving the uniformity of the flow distribution of the heat exchange medium between the cold plate structures 2 in the water distributor 6, so that each cold plate structure 2 has the same heat dissipation effect on the corresponding optical module, avoiding the phenomenon of a single optical module having a higher temperature. On the other hand, the cold plate structures 2 connected to the same water distributor 6 are all connected in parallel, which can minimize the flow resistance of the overall liquid cooling structure while ensuring the heat dissipation performance of the optical module, thereby effectively reducing the power consumption generated by the operation of the overall liquid cooling structure.

[0046] In one embodiment of the present invention, a thermally conductive material (not shown in the figure) is arranged between the optical module and the cold plate structure 2, and the side of the thermally conductive material facing the optical module can fit the surface of the optical module, and the side of the thermally conductive material facing the cold plate structure 2 can fit the surface of the cold plate structure 2, thereby avoiding a small gap between the surface of the cold plate structure 2 and the surface of the optical module, thereby preventing air from accumulating between the surface of the cold plate structure 2 and the surface of the optical module to generate a high interface thermal resistance and cause chip overheating. The thermally conductive material can increase the contact tightness between the optical module and the cold plate structure 2, effectively improve the heat transfer effect between the optical module and the cold plate structure 2, and then improve the heat dissipation effect of the optical module.

[0047] When the present invention is used, when the optical module is not inserted into the assembly, the cold plate structure 2 can enter the assembly. After the optical modules are inserted into the assembly in turn and connected to the system, the optical modules will support the cover plate 202, and the support spring 402 is compressed to a certain extent by the corresponding cover plate. The overall cold plate structure 2 automatically adjusts the floating amplitude according to the position of the optical module. The top surface of the cover plate 202 is tightly fitted with the bottom surface of the optical module. The heat exchange medium enters the water inlet cavity 601 through the water inlet pipe, and the heat exchange medium in the water inlet cavity 601 enters the heat exchange in each cold plate structure 2 through the hose 8. Channel 3, the heat exchange medium moves from the liquid inlet of the heat exchange channel 3 to the liquid outlet of the heat exchange channel 3 and then enters the drainage chamber 602, the heat exchange medium in the drainage chamber 602 is discharged through the outlet pipe, completing the circulation of the heat exchange medium, the heat generated by the optical module is transferred to the cover plate 202 and the bottom plate 201, the heat on the cover plate 202 and the bottom plate 201 is transferred to the heat exchange medium circulating in the heat exchange channel 3, the heat exchange medium takes away the heat on the cover plate 202 and the bottom plate 201, the cover plate 202 continuously absorbs the heat of the optical module to ensure the heat dissipation effect of the optical module.

[0048] In summary, the cold plate structure 2 has a certain upward and downward floating space relative to the assembly. After the optical module is inserted into the assembly, the optical module can fit tightly against the surface of the cold plate structure 2 to ensure the heat dissipation effect of the optical module. Moreover, the cold plate structure 2 automatically adjusts the floating amplitude according to the position of the optical module to ensure that each optical module connected to the system can fully contact and dissipate heat with the cold plate structure 2, further ensuring the heat dissipation effect of the optical module.

[0049] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0050] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
