Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation and airflow guiding devices, and in particular to an active heat dissipation and airflow guiding device with a multi-layer microcavity structure. Background Technology

[0002] Active cooling and heat dissipation devices are equipment used for efficient heat dissipation. They are typically used in high-power-density scenarios such as electronic devices, optoelectronic devices, and energy systems. Their core function is to guide the flow of cooling fluid to remove heat from heat-generating components, thereby achieving temperature control and equipment protection.

[0003] In the prior art, active heat dissipation and diversion devices dissipate heat through the internal flow of coolant. Since the internal flow channels of current devices are mostly spiral-shaped, the heat dissipation effect of the coolant near the channel is different from that of the original channel, resulting in uneven heat dissipation. Furthermore, some impurities will mix into the coolant during circulation, making it easy for the channel to become blocked when the coolant flows in the channel. Utility Model Content

[0004] The purpose of this invention is to provide an active heat dissipation and flow guiding device with a multi-layer microcavity structure, in order to solve the problem mentioned in the background art that the internal flow channels of current devices are mostly spiral-shaped, which makes the heat dissipation effect of the coolant near the channel different from the original channel when the coolant flows, resulting in uneven heat dissipation effect of the device. Secondly, when the coolant is circulated, some impurities will mix into the coolant, making it easy for the channel to become blocked when the coolant flows in the channel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a multi-layer microcavity mechanism, comprising a first heat dissipation plate, a first through groove, a water outlet groove, a second heat dissipation plate, a second through groove, a third through groove, a third heat dissipation plate, a fourth through groove, a fifth through groove, a hexagonal microcavity, and a microcavity connecting groove. A heat-conducting plate is provided at the bottom of the multi-layer microcavity mechanism, and a fixing plate is provided on the outer wall of the multi-layer microcavity mechanism.

The coolant circulation mechanism includes a coolant tank, an inlet pipe, a small water pump, an extension pipe, an outlet hose, a sealing pipe, a connecting pipe, an externally threaded pipe, an internally threaded ring, a filter pipe, a filter element, and a sealing connecting block.

[0006] In a preferred embodiment, the top of the first heat sink is provided with a first through groove, and a water outlet groove is provided on one side of the first heat sink. The top of the first heat sink is fixedly connected to the bottom of the second heat sink, and the bottom of the second heat sink is provided with a second through groove. The bottom of the first heat sink is fixedly connected to the top of the heat conduction plate.

[0007] In a preferred embodiment, the top of the second heat sink is provided with a third through groove, the top of the second heat sink is fixedly connected to the bottom of the third heat sink, the bottom of the third heat sink is provided with a fourth through groove, and one side of the third heat sink is provided with a fifth through groove.

[0008] In a preferred embodiment, the first heat sink, the second heat sink, and the third heat sink are all provided with hexagonal microcavities inside, and the hexagonal microcavities are connected to each other by microcavity connecting grooves. The interiors of the first through groove and the water outlet groove are respectively connected to the hexagonal microcavities inside the first heat sink, and the interiors of the first through groove and the second through groove are connected.

[0009] In a preferred embodiment, the second and third through slots are respectively connected to the hexagonal microcavities inside the second heat sink, the third through slot is connected to the interior of the fourth through slot, and the fourth and fifth through slots are respectively connected to the interior of the hexagonal microcavities.

[0010] In a preferred embodiment, the inner side of the fixing plate is fixedly connected to both sides of the coolant tank, one side of the first heat dissipation plate is fixedly connected to one end of the water inlet pipe, and the inside of the water outlet trough is connected to the water inlet pipe. The other end of the water inlet pipe is fixedly connected to the water inlet of the small water pump, and the water outlet of the small water pump is fixedly connected to one end of the extension pipe. The small water pump is located inside the coolant tank.

[0011] In a preferred embodiment, the inner wall of the coolant reservoir is fixedly connected to the outer wall of the outlet hose, and one end of the outlet hose located outside the coolant reservoir is fixedly connected to the top of the sealing pipe. One side of the third heat dissipation plate is fixedly connected to one end of the connecting pipe, and the interior of the fifth through groove communicates with the connecting pipe. The other end of the connecting pipe is fixedly connected to the bottom end of the external threaded pipe.

[0012] In a preferred embodiment, the outer wall of the externally threaded tube is threadedly connected to the inner wall of the internally threaded ring, the top end of the internally threaded ring is fixedly connected to the bottom end of the filter tube, the inner wall of the filter tube is movably connected to the outer wall of the filter element, the top of the filter tube is fixedly connected to the bottom of the sealing connection block, and the inner wall of the sealing connection block is movably connected to the outer wall of the sealing tube.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, coolant enters the interior of the fifth channel through the connecting pipe, allowing the coolant to circulate through the hexagonal microcavities and connecting grooves inside the third heat dissipation plate. It then flows through the fourth and third channels into the hexagonal microcavities and connecting grooves inside the second heat dissipation plate, and then through the second and first channels into the hexagonal microcavities and connecting grooves inside the first heat dissipation plate. The arrangement of the first, second, and third heat dissipation plates and the heat-conducting plate dissipates heat from the heat-generating areas. The coolant then flows out through the outlet channel and into the coolant reservoir through the inlet pipe and extension pipe. The interconnected and uniform arrangement of the hexagonal microcavities and connecting grooves, along with the multi-layered arrangement of the first, second, and third heat dissipation plates, ensures more uniform flow of coolant within these plates, resulting in more even heat dissipation.

[0014] 2. In this utility model, coolant enters the interior of the filter tube through the outlet hose and is filtered by the filter element inside the filter tube. By pulling out the outlet hose and the sealing tube, and then rotating the filter tube, the internal threaded ring is driven to rotate. The internal threaded ring rotates on the outer wall of the external threaded tube, thereby disassembling and replacing the filter tube. This facilitates the cooling of impurities in the coolant, avoids looking down into the hexagonal microcavities and microcavity connecting grooves, and also facilitates the replacement of the filter tube.

Finally, it flows through the second... The through-slot 105 and the first through-slot 102 flow into the hexagonal microcavity 110 and the microcavity connecting groove 111 inside the first heat sink 101. The heat sink is cooled by the arrangement of the first heat sink 101, the second heat sink 104, the third heat sink 107 and the heat conducting plate 2.
