Description

Technical Field

[0001] This invention belongs to the technical field of outdoor heat dissipation equipment, and particularly relates to an enhanced heat dissipation device and its usage method. Background Technology

[0002] With the upgrading and iteration of outdoor communication products, especially the development of 5G products, the heat consumption of the whole device has increased significantly. At the same time, due to the frequent occurrence of extreme and harsh environments, more stringent heat dissipation environments are required for the passive heat dissipation equipment of outdoor communication products.

[0003] Currently, the requirements for heat dissipation technology for electronic devices are becoming increasingly stringent. To cope with these demanding heat dissipation requirements, the mainstream approaches currently adopted are as follows: First, increase the volume of the external die-cast shell of outdoor communication products and increase the size of the fins to improve heat dissipation; second, increase the copper content of the single board to improve heat dissipation.

[0004] Each of the above methods has certain problems. First, increasing the size of outdoor communication products to increase the fin area leads to an increase in the overall weight of the equipment, which in turn increases the cost. At the same time, it increases the footprint of a single unit, which further increases the cost. Increasing the copper content of a single board further increases the overall cost. Moreover, this solution cannot be implemented in some cases, such as under a chip with a dense number of pins on the bottom side, where the feasibility of adding through holes or increasing the copper content is questionable.

[0005] Existing outdoor communication products are often located in areas with relatively stable ambient temperatures. For example, Tencent and Huawei have both set up their servers in Guizhou. In such an outdoor environment, there is abundant wind energy. Therefore, how to effectively utilize renewable wind energy to dissipate heat from outdoor communication products such as servers is worth studying. Summary of the Invention

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0037] Combination Figures 1 to 3As shown, this embodiment provides an enhanced heat dissipation device to enhance heat dissipation for outdoor communication products, including...

[0038] Product body 100, in this embodiment, product body 100 is an outdoor communication product or outdoor communication equipment.

[0039] The enhanced heat dissipation device in this embodiment also includes a flow equalization device 200, which is disposed below the product body 100. The flow equalization device 200 includes a conical flow equalization cavity 10 and a flow equalization plate 20. The shorter end of the conical flow equalization cavity 10 corresponds to the lower part of the product body 100, and the flow equalization plate 20 is located inside the product body 100. The flow equalization device 200 can make the gas enter the product body 100 more evenly.

[0040] Specifically, the conical flow equalization cavity 10 has a flow equalization outlet 11 at the top and a flow equalization inlet 12 at the bottom. The diameter of the flow equalization outlet 11 is smaller than the diameter of the flow equalization inlet 12. The flow equalization outlet 11 corresponds to the bottom of the product body 100. There is at least one flow equalization plate 20. The flow equalization plate 20 has flow equalization holes 21. The gas entering the conical flow equalization cavity 10 is evenly distributed into the product body 100 under the flow equalization effect of the flow equalization plate 20, so as to dissipate heat from the product body 100.

[0041] In this embodiment, the flow equalization holes 21 diffuse outward from the center of the flow equalization plate 20 to form a multi-level flow equalization hole 21 structure, so as to ensure that the gas output of each level of flow equalization hole 21 structure is the same, thereby achieving the purpose of gas homogenization.

[0042] The enhanced heat dissipation device in this embodiment also includes a power unit 300, which includes a follower structure 30, a transmission structure 40, a heat dissipation structure 50, and an energy storage structure 60. The follower structure 30 is connected to the transmission structure 40. The heat dissipation structure 50 is located at the longer end of the conical flow equalization cavity 10. When the product body 100 needs heat dissipation, the heat dissipation structure 50 is connected to the transmission structure 40. When the product body 100 does not need heat dissipation, the energy storage structure 60 is connected to the transmission structure 40. The power unit 300 can effectively utilize the wind energy at the location of the communication product, further enhancing the heat dissipation effect on outdoor communication products.

[0043] In this embodiment, the follower structure 30 includes a follower shaft 31 and a follower fan blade 32 located at the top of the follower shaft 31. The follower fan blade 32 is a cup-shaped structure. There are at least two follower fan blades 32, which are distributed circumferentially along the follower shaft 31. Under the action of wind energy, the follower fan blade 32 rotates, which drives the follower shaft 31 to rotate, realizing the conversion of wind energy into kinetic energy.

[0044] Furthermore, the transmission structure 40 includes a transmission shaft 41 and a transmission gear set 42 located on the transmission shaft 41. The transmission gear set 42 includes a main transmission gear 421 and a secondary transmission gear 422. The main transmission gear 421 is fixed on the follower shaft 31, and the secondary transmission gear 422 is fixed on the transmission shaft 41 and meshes with the main transmission gear 421. When the follower shaft 31 rotates, it will drive the main transmission gear 421 to rotate. The main transmission gear 421 meshes with the secondary transmission gear 422, and when the secondary transmission gear 422 rotates, it drives the transmission shaft 41 to rotate.

[0045] In this embodiment, the heat dissipation structure 50 includes a heat dissipation fan 51 and a drive gear set 52 for driving the heat dissipation fan 51. The heat dissipation fan 51 is installed inside the longer end of the conical flow equalization cavity 10. When the drive shaft 41 is connected and engaged with the drive gear set 52, the drive gear set 52 will drive the heat dissipation fan 51 to rotate, thereby enhancing the heat dissipation of the outdoor communication product.

[0046] Specifically, the cooling fan 51 is a cross-flow fan, and the drive gear set 52 includes a drive main gear 521, a first auxiliary gear 522, and a second auxiliary gear 523. The drive main gear 521 is concentrically arranged with the transmission shaft 41. The first auxiliary gear 522 and the second auxiliary gear 523 are located at both ends of the drive main gear 521, respectively. When the number of first auxiliary gears 522 is odd, the number of second auxiliary gears 523 is even. When the number of first auxiliary gears 522 is even, the number of second auxiliary gears 523 is odd. The first auxiliary gear 522 and the second auxiliary gear 523 are arranged with odd and even numbers to ensure that the airflow of the cooling fan 51 is always upward, thereby ensuring effective heat dissipation for outdoor communication products.

[0047] In this embodiment, the energy storage structure 60 includes an energy storage drive 61 and an energy storage module 62. The energy storage drive 61 is connected to the drive shaft 41 via an energy storage gear. The energy storage gear and the drive shaft 41 are concentrically arranged. The energy storage module 62 is electrically connected to the energy storage drive 61. The cooling fan 51 is electrically connected to the energy storage module 62. When the drive shaft 41 is connected and engaged with the energy storage gear, it drives the energy storage gear to rotate, thereby driving the energy storage drive 61 to perform transmission and store kinetic energy. The stored kinetic energy is converted into electrical energy and stored in the energy storage module 62. In this embodiment, the energy storage drive 61 is a generator, and the energy storage module 62 is a power storage device.

[0048] Furthermore, the power unit 300 in this embodiment also includes a switching structure 70, which includes a control unit 71, a first electromagnet 72, and a second electromagnet 73. The first electromagnet 72 and the second electromagnet 73 are located at the two ends of the transmission shaft 41, respectively. The first electromagnet 72 and the second electromagnet 73 are energized in opposite states. When the first electromagnet 72 is energized, the transmission shaft 41 is connected to the heat dissipation structure 50. When the second electromagnet 73 is energized, the transmission shaft 41 is connected to the energy storage structure 60. The control unit 71 controls the on / off state of the first electromagnet 72 and the second electromagnet 73, so that the energization states of the first electromagnet 72 and the second electromagnet 73 are reversed, thereby changing the connection state of the transmission shaft 41 with the heat dissipation structure 50 or the energy storage structure 60.

[0049] In this embodiment, the following process is first implemented: the follower structure 30 collects wind energy at the location of the outdoor communication product and converts it into kinetic energy of the follower shaft 31. The follower shaft 31 then transmits the kinetic energy to the heat dissipation structure 50 or the energy storage structure 60 via the transmission structure 40. When the kinetic energy is transmitted to the heat dissipation structure 50, the cooling fan 51 rotates. Under the flow equalization effect of the flow equalization plate 20, the gas generated by the cooling fan 51 is evenly introduced into the outdoor communication product to enhance heat dissipation. When the kinetic energy is transmitted to the energy storage structure 60, the kinetic energy is converted into electrical energy by the energy storage transmission machine 61 and stored in the energy storage module 62.

[0050] Furthermore, in this embodiment, the energy storage module 62 is electrically connected to the cooling fan 51. When the outdoor communication product needs to further enhance heat dissipation, the energy storage module 62 is activated to increase the power of the cooling fan 51, thereby enhancing the heat dissipation of the outdoor communication product and improving the heat dissipation effect.

[0051] like Figure 4 As shown, this embodiment also discloses a method for using an enhanced heat dissipation device, including the following steps:

[0052] S1. Set the target temperature point Si of the product body 100. The target temperature point is set by the control unit 71 of the switching structure 70. The target temperature point is the critical point of the heat dissipation capacity of the outdoor communication product itself.

[0053] S2. Read the actual temperature Ti of the product body 100 and compare Ti with Si. The actual temperature of the product body 100 is read by a temperature sensor and transmitted to the control unit 71. The control unit 71 compares Ti with Si.

[0054] S3. When the actual temperature Ti of the product body 100 is higher than the target temperature Si, the first electromagnet 72 is energized, the transmission shaft 41 is connected to the heat dissipation structure 50, and the heat dissipation fan 51 is driven to rotate to dissipate heat and cool down the product body 100.

[0055] S4. When the actual temperature Ti of the product body 100 is lower than the target temperature Si, the second electromagnet 73 is energized, the transmission shaft 41 is connected to the energy storage structure 60, the energy storage transmission 61 of the energy storage structure 60 operates, and the kinetic energy is stored in the energy storage module 62.

[0056] In summary, the enhanced heat dissipation device provided by this invention can enhance the heat dissipation of outdoor communication products. It employs a follower structure 30 to gather external wind energy, and with the cooperation of the transmission structure 40 and the heat dissipation structure 50, it enhances the heat dissipation of the outdoor communication products. When the outdoor communication products do not require heat dissipation, the wind energy gathered by the follower structure 30 is stored in cooperation with the transmission structure 40 and the energy storage structure 60, improving energy utilization. Furthermore, this invention has a simple structure, strong stability, and can be used effectively in cycles. It eliminates the need to increase the size of the outdoor communication products to improve heat dissipation, further reducing costs. The energy storage structure 60 is electrically connected to the cooling fan 51. When the transmission structure 40 and the heat dissipation structure 50 cannot meet the heat dissipation requirements of the outdoor communication products, the energy storage structure 60 will further increase the power of the cooling fan 51, improving the heat dissipation capacity of the outdoor communication products.
