Description

Technical Field

[0001] This utility model belongs to the field of thermal management technology, specifically relating to an embedded manifold microchannel heat dissipation device suitable for the aerospace field. Background Technology

[0002] Embedded manifold microchannel heat sinks play a crucial role in high-power-density equipment. Their main function is to efficiently transfer heat away from heat-generating elements, ensuring stable operation of the equipment within a safe temperature range. To further improve heat dissipation, in the aerospace field, embedded manifold microchannel heat sinks are often used in conjunction with external heat dissipation systems to ensure efficient heat dissipation. External heat dissipation systems increase airflow speed and volume by pushing airflow across the outer surface of the embedded manifold microchannel or through additional heat sinks, thereby improving convective heat transfer efficiency.

[0003] In existing technologies, external embedded manifold microchannel heat dissipation devices in the hydraulic aerospace field typically need to operate stably for a long time in extreme environments. To ensure good sealing and airflow control, some dust grilles are usually tightly connected to the surrounding structure. This makes it difficult to disassemble and clean them after a long period of use when a large amount of dust accumulates. If the grilles are not cleaned in time, the airflow will be significantly reduced, resulting in a significant decrease in heat dissipation efficiency. This may lead to the heat dissipation device being unable to effectively remove heat from the outer surface of the embedded manifold microchannel, thus causing the device to overheat.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1-5 This is an embodiment of the present invention, which provides an embedded manifold microchannel heat dissipation device suitable for the aerospace field. It can achieve the effect of removing heat from the outer surface of the embedded manifold microchannel through a single driving source while intermittently cleaning the surface of the dustproof grille 109.

[0027] The cooling mechanism 100 includes a fixed box 101, a servo motor 102 adapted to be installed on the outer surface of the fixed box 101, a connecting column 103 fixedly installed on the output end of the servo motor 102 via a coupling, a first belt reel 104 fixedly sleeved on the outer surface of the connecting column 103, a transmission belt 105 sleeved on the outer surface of the first belt reel 104, a second belt reel 106 sleeved on the inner surface of the other end of the transmission belt 105, a driven column 107 fixedly connected to the inner surface of the second belt reel 106, an impeller 108 fixedly sleeved on the outer surface of the driven column 107, and a dustproof grille 109 fixedly installed on the outer surface of the fixed box 101 and used in conjunction with the impeller 108.

[0028] It should be noted that when the servo motor 102 starts working, the connecting column 103 rotates together with the output shaft of the servo motor 102, transmitting power to the first pulley 104. This causes the first pulley 104 to rotate at high speed via the transmission belt 105, which in turn drives the second pulley 106, the driven column 107, and the impeller 108. The powerful airflow generated by the rotation of the impeller 108 carries away heat from the outer surface of the embedded manifold microchannel through forced convection, thus achieving a heat dissipation effect.

[0029] And a cleaning mechanism 200 used in conjunction with the dust removal mechanism 109 to remove dust from the surface of the dustproof grille 109.

[0030] Specifically, the through end of the impeller 108 is fixedly installed on the inner wall of the fixed box 101 by a bearing, and a rotating bearing sleeve is installed at the connection between the impeller 108 and the fixed box 101. The dustproof grille 109 is located inside the fixed box 101.

[0031] Furthermore, the cleaning mechanism 200 includes a first pulley 201 fixedly sleeved on the outer surface of the connecting column 103, a belt 202 sleeved on the outer surface of the first pulley 201, a second pulley 203 sleeved on the inner surface of the other end of the belt 202, a rotating shaft 204 fixedly installed on the outer end face of the second pulley 203, a notched gear 205 fixedly sleeved on the outer surface of the rotating shaft 204, a complete gear 206 meshing with the outer surface of the notched gear 205, and a braking assembly 207 used to reduce the rotation frequency of the complete gear 206.

[0032] It should be noted that when the connecting column 103 rotates, it can also drive the first pulley 201 to rotate. Through the cooperation of the first pulley 201 and the belt 202, the second pulley 203, the rotating shaft 204 and the notched gear 205 are driven to rotate synchronously. When the notched gear 205 meshes with the complete gear 206, it can drive the complete gear 206 to rotate.

[0033] Preferably, the braking assembly 207 includes a movable toothed block 207a rotatably sleeved on the outer surface of the rotating shaft 204, and a tension spring 207b fixedly mounted on the outer surface of the notched gear 205 and used in conjunction with the movable toothed block 207a, with the other end of the tension spring 207b fixedly connected to the outer surface of the movable toothed block 207a.

[0034] It should be further explained that when the notched gear 205 rotates, the notched portion on its surface periodically disengages from the complete gear 206. When the notched gear 205 rotates to the point where its notched portion contacts the complete gear 206, the meshing relationship between the notched gear 205 and the complete gear 206 is temporarily interrupted, and the complete gear 206 is no longer driven. At this time, the movable tooth block 207a will mesh with the tooth profile of the complete gear 206, preventing the complete gear 206 from continuing to rotate. When the notched gear continues to rotate and its tooth profile contacts the complete gear 206 again, it will drive the movable tooth block 207a to rotate. The movable tooth block 207a will automatically reset under the action of the tension spring 207b, allowing the complete gear 206 to start rotating again, thereby reducing the rotation frequency of the complete gear 206.

[0035] It should be noted that the cleaning mechanism 200 also includes a transmission rod 208 fixedly connected to the inner surface of the complete gear 206, a reciprocating roller 209 fixedly sleeved on the outer surface of the transmission rod 208, a sleeve 210 slidably sleeved on the outer surface of the reciprocating roller 209, a scraper 211 fixedly installed on the outer surface of the sleeve 210 and used in conjunction with the dustproof grille 109, and a fixing frame 212 fixedly connected to the top of the fixing box 101 and a limiting rod 213 used in conjunction with the sleeve 210.

[0036] In this process, the transmission rod 208 and the reciprocating roller 209 are driven to rotate synchronously and intermittently by the complete gear 206, and the sleeve 210 is limited by the limiting rod 213, so that the sleeve 210 drives the scraper 211 to intermittently clean the surface of the dustproof grid 109.

[0037] Furthermore, the outer end face of the rotating shaft 204 is fixedly mounted on the outer surface of the fixed frame 212 by bearings, and a bearing sleeve that rotates in coordination is installed at the connection between the complete gear 206 and the fixed frame 212. The outer end face of the fixed frame 212 is fixedly mounted on the outer surface of the fixed box 101 by bearings.

[0038] Specifically, the inner surface of the sleeve 210 away from the reciprocating roller 209 slides in contact with the outer surface of the limiting rod 213, and the outer surface of the scraper 211 slides in contact with the outer surface of the dustproof grid 109.

[0039] When in use, the servo motor 102 is turned on, and the connecting column 103 rotates together with the output shaft of the servo motor 102, transmitting power to the first pulley 104. The first pulley 104 then rotates at high speed through the transmission belt 105 to the second pulley 106, the driven column 107, and the impeller 108. The powerful airflow generated when the impeller 108 rotates carries away heat from the outer surface of the embedded manifold microchannel through forced convection, achieving a heat dissipation effect.

[0040] The connecting column 103 drives the first pulley 201 to rotate synchronously. Then, through the engagement of the first pulley 201 and the belt 202, the second pulley 203, the rotating shaft 204, and the notched gear 205 rotate synchronously. When the notched gear 205 rotates, the notched portion on its surface periodically disengages from the complete gear 206. When the notched gear 205 rotates to the point where its notched portion contacts the complete gear 206, the meshing relationship between the two is temporarily interrupted, and the complete gear 206 is no longer driven. At this time, the movable tooth block 207a meshes with the tooth profile of the complete gear 206, preventing the complete gear 206 from continuing to rotate. As the notched gear continues to rotate, its toothed portion contacts the complete gear 206 again, causing the movable tooth block 207a to rotate. The movable tooth block 207a automatically resets under the action of the tension spring 207b, allowing the complete gear 206 to start rotating again. This causes the complete gear 206 to drive the transmission rod 208 and the reciprocating roller 209 to rotate synchronously and intermittently. Then, the sleeve 210 is limited by the limiting rod 213, causing the sleeve 210 to drive the scraper 211 to intermittently clean the surface of the dustproof grille 109. This achieves the effect of removing heat from the outer surface of the embedded manifold microchannel through a single drive source while intermittently cleaning the surface of the dustproof grille 109.

[0041] In summary, the cooling mechanism 100 can remove heat from the outer surface of the embedded manifold microchannel through forced convection, thus achieving a heat dissipation effect. Through the cooperation between the components in the cleaning mechanism 200, not only is the heat from the introduction of an additional driving source avoided, but the surface of the dustproof grille 109 can also be cleaned intermittently. This prevents the airflow of the dustproof grille 109 from decreasing while also preventing excessive friction between the scraper 211 and the dustproof grille 109, which would lead to a rapid reduction in service life.
