Abstract

This invention discloses a microchannel heat sink for communication equipment, belonging to the technical field of microchannel heat sinks. It includes a heat sink body, a flow divider, and a trigger. The heat sink body includes two symmetrically distributed manifolds. Multiple microchannel plates are evenly distributed between the manifolds and are vertically distributed along the manifolds. Multiple evenly distributed V-shaped fins are installed between the microchannel plates, and flow channels are formed within the microchannel plates. The microchannel plates are connected to both manifolds through these flow channels. This invention uses heat-absorbing fins to contact the heat source, rapidly transferring heat to the inner cavity of the heat-conducting block. The heat-conducting block absorbs heat and transfers it to the trigger rod. When the temperature of the heat-conducting block and the trigger rod exceeds 40-45°C, the trigger rod deforms and extends upwards, thereby pushing the sealing plug to open the flow divider, allowing more coolant to flow into the heat dissipation cavity to cope with the increased heat load and facilitate coolant entry into the heat dissipation cavity.

Description

Technical Field

[0001] The present invention relates to the technical field of micro-channel radiators, and more particularly to a micro-channel radiator for communication equipment. Background Art

[0002] Communication equipment refers to hardware equipment used to transmit, receive and process information between two or more locations. Large communication equipment generates a lot of heat during operation, and often requires the use of microchannel radiators for heat exchange. Since aluminum has a high thermal conductivity, microchannel radiators usually use aluminum radiators to quickly transfer heat from the heat source to the surface of the radiator and then dissipate it into the surrounding environment.

[0003] When the existing microchannel radiator is in use, the coolant is first pumped into the radiator's header through a feed pipe, and the header evenly distributes the coolant to the microchannels inside the radiator, and V-shaped fins are arranged between the spaced microchannels so that the heat in the microchannels can be dissipated through convection heat exchange between the fins and the surrounding air. At the same time, the coolant after heat exchange will converge to another header, and then return to the cooling system through a return pipe, ready to circulate again.

[0004] In actual use of the prior art, due to the excessive heat generated by communication equipment during high-intensity operation, if heat exchange is solely dependent on the coolant in the microchannel radiator, it may not be possible to remove all the heat in time, resulting in thermal runaway of the equipment and performance degradation. In addition, a large amount of dust and impurities will accumulate on the fins during long-term operation. These pollutants will hinder heat exchange and reduce heat dissipation efficiency. Therefore, in response to the above technical problems, it is necessary to provide a microchannel radiator for communication equipment. Summary of the invention

[0005] The object of the present invention is to provide a microchannel heat sink for communication equipment to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] A microchannel heat sink for communication equipment comprises a heat sink body, a flow divider and a trigger member, wherein the heat sink body comprises two symmetrically distributed headers, a plurality of microchannel plates are evenly distributed between a pair of the headers, and the microchannel plates are vertically distributed between the pair of headers, and a plurality of evenly distributed V-shaped fins are installed between the microchannel plates, a flow channel is opened in the microchannel plate, and the microchannel plate is connected to the pair of headers through the flow channel; the plurality of flow dividers are V-shaped structures and are evenly interspersed between the V-shaped fins, and a heat sink is arranged in the flow divider. The microchannel plate and the flow diversion member are connected at the connection point of the microchannel plate and the flow diversion member, and the flow channel of the microchannel plate is connected to the heat dissipation cavity through the flow diversion hole; a plurality of trigger members are correspondingly arranged inside the heat dissipation cavity, a heat conduction block is fixedly connected inside the heat dissipation cavity, and the heat conduction block is located at the top corner of the V-shaped structure on the heat dissipation cavity, and two V-shaped symmetrically distributed trigger rods are fixedly connected to the outer surface of the heat conduction block, and matching sealing plugs are correspondingly arranged at the flow diversion hole, and the sealing plug is located in the flow channel and seals the flow diversion hole, and the trigger rod and the sealing plug are fixedly connected.

[0008] As a further improvement of the present invention, a spoiler is provided in the inner cavity of the heat dissipation cavity, and the spoiler includes an elastic rod fixedly connected to a corresponding elastic rod on the heat conductive block, and a spoiler ball is fixedly connected to one end of the elastic rod. The spoiler introduces turbulence when the coolant flows through the heat dissipation cavity, thereby increasing the contact area and contact time between the coolant and the heat conductive block, thereby greatly improving the heat exchange efficiency and helping to take away the heat generated by the equipment more quickly. At the same time, the turbulence generated helps to evenly distribute the heat, prevent local overheating, and avoid the formation of hot spots, thereby improving the thermal stability and reliability of the equipment.

[0009] As a further improvement of the present invention, a seal is provided on the outer surface of the sealing plug, and the seal includes a hard sealing gasket fixedly installed on the outer surface of the sealing plug, and the hard sealing gasket is made of a hard sealing material. The outer surface of the hard sealing gasket is fixedly connected with a flexible sealing gasket, and the flexible sealing gasket is made of a flexible sealing material to ensure the tight closure of the diversion hole under normal conditions to prevent leakage of coolant. The flexible sealing gasket can fill the tiny gap between the hard sealing gasket and the diversion hole to enhance the sealing effect. When the sealing plug undergoes a slight displacement due to temperature changes, the flexible sealing gasket can maintain good sealing.

[0010] As a further improvement of the present invention, the spoiler ball is made of a lightweight material and has an uneven surface. The uneven surface of the spoiler ball can protect the spoiler ball from wear and tear caused by the flow of coolant.

[0011] As a further improvement of the present invention, the trigger rod is made of a shape memory alloy material, the temperature of the trigger rod when deformed by heat is 40-45°C, and the trigger rod has a tendency to extend and lengthen when the temperature is higher than the deformation temperature. Since the trigger rod is made of a shape memory alloy, when the temperature reaches and exceeds the temperature range of 40-45°C, the trigger rod will undergo a phase change, thereby causing it to extend and lengthen, and drive the sealing plug to open, allowing it to be diverted.

[0012] As a further improvement of the present invention, the end of the heat conductive block facing the heat source passes through the heat dissipation cavity and extends to the outside to be fixedly connected with a heat absorbing sheet, which is made of graphite material so that the heat absorbing sheet can quickly transfer the heat from the heat source to the heat conductive block.

[0013] As a further improvement of the present invention, an arc-shaped edge is provided at one end of the sealing plug close to the diversion hole. When the sealing plug is in an open state, its arc-shaped edge can guide the coolant to turn smoothly, reduce the turbulence and energy loss of the fluid during the turning, thereby increasing the speed of the coolant passing through the diversion hole. Conversely, when the sealing plug needs to be closed to prevent the coolant from flowing, its arc-shaped edge can form a tighter fit with the diversion hole, thereby providing a better sealing effect. By utilizing the concept of "boundary layer" in fluid dynamics, that is, when the fluid is close to the surface of an object, a nearly static thin layer will be formed. When the arc-shaped edge is closed, it can reduce the gap between the coolant and the sealing plug and the diversion hole, thereby reducing the possibility of coolant leakage.

[0014] As a further improvement of the present invention, a partition is provided inside one of the collecting pipes, and the partition divides the collecting pipe into a liquid inlet channel and a liquid return channel, thereby ensuring the one-way flow of the coolant, that is, the coolant enters from the liquid inlet channel, passes through the heat exchange in the heat dissipation cavity, and returns from the liquid return channel, thereby forming a closed-loop coolant circulation path. The partition helps to optimize the flow direction of the coolant and avoid short-circuiting of the fluid during the circulation process.

[0015] As a further improvement of the present invention, the liquid inlet channel is connected to a feed pipe, the liquid return channel is connected to a discharge pipe, a circulation system is arranged between the feed pipe and the discharge pipe, the circulation system includes existing components such as a micro pump, a micro valve and a micro filter. The circulation system is a vital component of the heat dissipation system, which is responsible for driving the circulation of the coolant between the radiator, the equipment heat source and the heat dissipation cavity, thereby realizing the effective transfer and dissipation of heat energy.

[0016] As a further improvement of the present invention, the bottom surface of the V-shaped fins of the radiator body are fixedly connected to two slots, the inside of the slots are clamped with buckles, and the outer surface of the buckles is fixedly connected to a recycling box, so that the recycling box can be disassembled through the slots and buckles, which is convenient for regular cleaning of dust and impurities collected in the recycling box.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] In this solution, the heat absorbing sheet is in contact with the heat source so as to quickly transfer the heat to the inner cavity of the heat conductive block, so that the heat conductive block absorbs the heat and transfers it to the trigger rod. When the temperature of the heat conductive block and the trigger rod exceeds 40-45°C, the trigger rod will deform and extend upward to become longer, thereby pushing the sealing plug to open the diversion hole, allowing more coolant to flow into the heat dissipation cavity to cope with the increased heat load, so that the coolant can enter the heat dissipation cavity. The V-shaped channel of the heat dissipation cavity can not only increase the contact area of ​​the coolant, but also optimize the fluid dynamics performance and improve the heat exchange efficiency, thereby avoiding the thermal runaway of the equipment and the performance degradation caused by simply using the coolant in the microchannel plate for heat exchange, thereby ensuring the stability and reliability of the equipment.

[0019] When the temperature transmitted to the trigger rod by the heat conductive block drops below 40-45°C, the trigger rod is prompted to return to its original shape. The reverse deformation of the trigger rod causes the sealing plug to move downward until the diversion hole is completely blocked. At the same time, the hard sealing gasket and the flexible sealing gasket on the surface of the sealing plug cooperate with each other when the diversion hole is closed to form a double sealing barrier, and the flexible sealing gasket fills any potential gaps to prevent coolant leakage, thereby improving the reliability and integrity of the seal.

[0020] When the coolant flows into the heat dissipation cavity, the elastic rod is bent due to fluid dynamics, thereby causing the spoiler ball to shake, breaking the original smooth laminar state, causing the fluid to form a more complex flow pattern to form turbulence, increasing the heat exchange efficiency between the fluid and the heat conductive block, and at the same time, the uneven surface of the spoiler ball can protect the spoiler ball from erosion and wear caused by the high-speed flowing coolant inside the microchannel plate, so that it can withstand long-term mechanical shock.

[0021] The spoiler ball can collide with the surface of the V-shaped fin, causing the dust and impurities on the surface of the V-shaped fin to fall into the recycling box below, realizing the self-cleaning function, ensuring that the radiator body maintains efficient operation for a long time, and avoiding the accumulation of a large amount of dust and impurities on the surface of the V-shaped fin due to long-term operation, which hinders heat exchange and reduces heat dissipation efficiency, thereby keeping the V-shaped fin clean. At the same time, the recycling box can be removed through the buckles and slots, making it convenient for the staff to clean up the dust and garbage in the recycling box.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] See also Figure 1-7 A microchannel heat sink for communication equipment includes a heat sink body 1, a diverter 5 and a trigger 8. The heat sink body 1 includes two symmetrically distributed headers 2, a plurality of microchannel plates 3 are evenly distributed between a pair of headers 2, and the microchannel plates 3 are vertically distributed between the pair of headers 2. A plurality of evenly distributed V-shaped fins 4 are installed between the microchannel plates 3. A flow channel is opened in the microchannel plate 3, and the microchannel plate 3 is connected to the pair of headers 2 through the flow channel.

[0039] Specifically, multiple diverter members 5 are of V-shaped structure and are evenly interspersed between the V-shaped fins 4, a heat dissipation cavity 501 is arranged in the diverter member 5, a pair of symmetrically distributed diverter holes 502 are opened at the connection between the microchannel plate 3 and the diverter member 5, and the flow channel of the microchannel plate 3 is connected with the heat dissipation cavity 501 through the diverter hole 502; multiple trigger members 8 are correspondingly arranged inside the heat dissipation cavity 501, a heat conductive block 801 is fixedly connected inside the heat dissipation cavity 501, and the heat conductive block 801 is located at the top corner of the V-shaped structure on the heat dissipation cavity 501, and two V-shaped symmetrically distributed trigger rods 802 are fixedly connected to the outer surface of the heat conductive block 801, a matching sealing plug 803 is correspondingly arranged at the diverter hole 502, and the sealing plug 803 is located in the flow channel and seals with the diverter hole 502, and the trigger rod 802 and the sealing plug 803 are fixedly connected.

[0040] The trigger rod 802 is made of shape memory alloy material. The temperature of the trigger rod 802 when heated and deformed is 40-45°C, and the trigger rod 802 has a tendency to extend and lengthen when it is higher than the deformation temperature. The trigger rod 802 adopts a special plate made of shape memory alloy material. When the temperature of the trigger rod 802 reaches or exceeds the transformation temperature of the shape memory alloy of 40-45°C, the trigger rod 802 will be thermally expanded and deformed, thereby pushing the sealing plug 803 to open or adjust the size of the diverter hole 502, and automatically adjust the flow rate of the coolant to adapt to different heat loads. On the contrary, when the temperature drops, the trigger rod 802 will return to its original shape, prompting the sealing plug 803 to close the feed port and reduce the flow rate of the coolant. The end of the heat conductive block 801 facing the heat source passes through the heat dissipation cavity 501 and extends to the outside to be fixedly connected with a heat absorbing sheet 804. The heat absorbing sheet 804 is made of graphite material. An arc shape is provided at one end of the sealing plug 803 close to the diverter hole 502.

[0041] Furthermore, as the heat generated by the operation of the communication equipment increases, the heat absorbing sheet 804 contacts the heat source and can quickly transfer the heat to the inner cavity of the heat conductive block 801 through its own graphite material, so that the heat conductive block 801 absorbs the heat and transfers it to the trigger rod 802. When the temperature of the heat conductive block 801 and the trigger rod 802 exceeds 40-45°C, the trigger rod 802 will deform and extend upward, thereby pushing the sealing plug 803 to open the diverter hole 502, allowing more coolant to flow into the heat dissipation cavity 501 to cope with the increased heat load, so that the coolant can enter the heat dissipation cavity 501 and pass through the V-shaped passage of the heat dissipation cavity 501. The channel can not only increase the contact area of ​​the coolant, so as to improve the heat exchange efficiency, but also avoid the thermal runaway of the equipment and the degradation of performance caused by simply using the coolant in the microchannel plate 3 for heat exchange, so as to achieve local heat dissipation, thereby increasing the coolant circulation area. As the temperature of the communication equipment decreases, the heat transferred to the trigger rod 802 through the heat conductive block 801 decreases, causing the temperature of the trigger rod 802 to drop below 40-45°C, causing the trigger rod 802 to return to its original shape, and the reverse deformation of the trigger rod 802 causes the sealing plug 803 to move downward until the diversion hole 502 is completely blocked.

[0042] Embodiment 2:

[0043] Reference Figure 1-Figure 7 , which is the second new embodiment of the present invention, and this embodiment is based on the previous embodiment. The radiator body 1 includes two symmetrically distributed headers 2, a plurality of microchannel plates 3 are evenly distributed between a pair of headers 2, and the microchannel plates 3 are vertically distributed between the pair of headers 2, and a plurality of evenly distributed V-shaped fins 4 are installed between the microchannel plates 3, and flow channels are opened in the microchannel plates 3, and the microchannel plates 3 are connected to the pair of headers 2 through the flow channels.

[0044] Specifically, the inner cavity of the heat dissipation cavity 501 is provided with a spoiler 6, which includes an elastic rod 601 fixedly connected to the corresponding heat conductive block 801, and one end of the elastic rod 601 is fixedly connected to a spoiler ball 602. The spoiler ball 602 is made of lightweight material and has an uneven surface. The uneven surface of the spoiler ball 602 can protect the spoiler ball 602 from wear caused by the flow of coolant.

[0045] A sealing member 7 is provided on the outer surface of the sealing plug 803. The sealing member 7 includes a hard sealing pad 701 fixedly mounted on the outer surface of the sealing plug 803. The hard sealing pad 701 is made of a hard sealing material. A flexible sealing pad 702 is fixedly connected to the outer surface of the hard sealing pad 701. The flexible sealing pad 702 is made of a flexible sealing material. The hard sealing pad 701 is made of a hard sealing material and can be replaced by hard plastic, polytetrafluoroethylene, ceramic and other materials to enhance the sealing performance of the sealing plug 803 and ensure that the coolant does not leak from the diversion hole 502. The flexible sealing pad 702 is made of a flexible sealing material and can be replaced by silicone rubber, rubber, fluororubber and other materials. When used in conjunction with the hard sealing pad 701, it can fill the small gap between the hard sealing pad 701 and the sealing surface, thereby further improving the reliability of the seal.

[0046] A partition 10 is arranged inside one of the collecting pipes 2, and the partition 10 divides the collecting pipe 2 into a liquid inlet channel and a liquid return channel. The liquid inlet channel is connected to a feed pipe, and the liquid return channel is connected to a discharge pipe. A circulation system is arranged between the feed pipe and the discharge pipe. The bottom surface of the radiator body 1 located at the V-shaped fin 4 is fixedly connected to two card slots 9, and a buckle 11 is clamped inside the card slot 9, and a recovery box 12 is fixedly connected to the outer surface of the buckle 11.

[0047] Furthermore, when the coolant flows through, the elastic rod 601 will bend due to the effect of fluid dynamics, thereby causing the spoiler ball 602 to shake, breaking the originally smooth laminar state, and prompting the fluid to form a more complex flow pattern to form turbulence, thereby increasing the heat exchange efficiency between the fluid and the heat conductive block 801, and increasing the contact area and contact strength between the coolant and the surface of the heat conductive block 801, thereby improving the heat exchange efficiency. At the same time, the uneven surface of the spoiler ball 602 can protect the spoiler ball 602 from erosion and wear caused by the high-speed flowing coolant inside the microchannel plate 3, so that it can withstand long-term mechanical shock.

[0048] When the spoiler ball 602 is able to collide with the surface of the V-shaped fin 4, the dust and impurities on the surface of the V-shaped fin 4 are caused to fall into the recovery box 12 below, thereby realizing the self-cleaning function, ensuring that the radiator body 1 maintains efficient operation for a long time, and avoiding the accumulation of a large amount of dust and impurities on the surface of the V-shaped fin 4 due to long-term operation, which hinders heat exchange and reduces heat dissipation efficiency, thereby maintaining the clean state of the V-shaped fin 4 and reducing the risk of equipment damage caused by overheating.

[0049] The working principle of the present invention is as follows: when in use, the radiator body 1 is first installed at an appropriate position of the communication equipment to ensure that it is in close contact with the heat source, and the external coolant circulation system is connected through the feed pipe and the discharge pipe to ensure that the coolant can smoothly flow into the liquid inlet channel and out of the liquid return channel. At the same time, the recovery box 12 is firmly fixed to the surface of the radiator body 1 through the mutual cooperation of the card slot 9 and the buckle 11, and is located below the multiple V-shaped fins 4. Subsequently, the external coolant pump is turned on to allow the coolant to begin to circulate in the liquid inlet channel and the liquid return channel, thereby starting the heat exchange process. As the heat generated by the operation of the communication equipment increases, the heat absorbing sheet 804 contacts the heat source, and can quickly transfer it to the inner cavity of the heat conductive block 801 through its own graphite material, so that the heat conductive block 801 absorbs the heat and transfers it to the trigger rod 802. When the temperature of the heat conductive block 801 and the trigger rod 802 exceeds 40-45°C, the trigger rod 802 will be deformed and extend upward to become longer, thereby pushing the sealing plug 803 to open the diversion hole 502 (such as Figure 4 As shown), more coolant is allowed to flow into the heat dissipation cavity 501, and the coolant flow rate is automatically adjusted to cope with the increased heat load so that the coolant can enter the heat dissipation cavity 501. The V-shaped channel of the heat dissipation cavity 501 can not only increase the contact area of ​​the coolant, but also optimize the fluid dynamics performance and improve the heat exchange efficiency, thereby avoiding thermal runaway of the equipment and performance degradation caused by simply using the coolant in the microchannel plate 3 for heat exchange, thereby ensuring the stability and reliability of the equipment.

[0050] When the coolant flows through, the elastic rod 601 will bend due to the effect of fluid dynamics, thereby causing the spoiler ball 602 to shake, breaking the originally smooth laminar state, and prompting the fluid to form a more complex flow pattern to form turbulence, thereby increasing the heat exchange efficiency between the fluid and the heat conductive block 801, and increasing the contact area and contact strength between the coolant and the surface of the heat conductive block 801, thereby accelerating the heat transfer speed and improving the heat exchange efficiency. At the same time, the uneven surface of the spoiler ball 602 can protect the spoiler ball 602 from erosion and wear by the high-speed flowing coolant inside the microchannel plate 3, so that it can withstand long-term mechanical impact, and can also maintain the integrity and functionality of the spoiler ball 602, ensuring its free movement in the heat dissipation cavity 501, thereby reducing the frequency of replacement of the spoiler ball 602 due to wear.

[0051] At the same time, when the spoiler ball 602 can collide with the surface of the V-shaped fin 4, the dust and impurities on the surface of the V-shaped fin 4 are shaken off into the recycling box 12 below, realizing the self-cleaning function, ensuring that the radiator body 1 maintains efficient operation for a long time, and avoiding the accumulation of a large amount of dust and impurities on the surface of the V-shaped fin 4 due to long-term operation, which hinders heat exchange and reduces heat dissipation efficiency, thereby maintaining the clean state of the V-shaped fin 4 and reducing the risk of equipment damage caused by overheating. At the same time, holding the recycling box 12, moving the recycling box 12 upwards separates the buckle 11 from the slot 9, so that the recycling box 12 can be quickly disassembled for cleaning, which is convenient for the staff to clean the dust and garbage in the recycling box 12.

[0052] As the temperature of the communication device decreases, the heat transferred to the trigger rod 802 through the heat conductive block 801 decreases, causing the temperature of the trigger rod 802 to drop below 40-45°C, causing the trigger rod 802 to return to its original shape. The reverse deformation of the trigger rod 802 causes the sealing plug 803 to move downward until the diversion hole 502 is completely blocked (such as Figure 3 As shown), the hard sealing gasket 701 and the flexible sealing gasket 702 on the surface of the sealing plug 803 cooperate with each other when the diversion hole 502 is closed to form a double sealing barrier. The hard sealing gasket 701 ensures the rigidity and stability of the sealing structure, while the flexible sealing gasket 702 fills any potential gaps to prevent coolant leakage, thereby improving the reliability and integrity of the seal.

[0053] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
