Description

Technical Field

[0001] The present invention relates to the technical field of communication heat dissipation fixing devices, and in particular to a heat dissipation fixing device for communication engineering equipment. Background Art

[0002] Communication engineering is also known as telecommunication engineering, formerly known as long-distance communication engineering and weak current engineering. It is an important branch of electronic engineering. The most commonly used in communication engineering is the communication box, which is generally installed outdoors for communication.

[0003] In existing communication projects, when fixing the communication box, the general fixing method is to cover the communication circuit board with a protective cover, and fix it by screws or clip-on installation. Generally, a cooling fan is arranged inside the protective cover for heat dissipation, and effective heat dissipation effect cannot be achieved in high temperature weather; and a heat dissipation groove is also required to be opened on the side of the protective cover, which is easy to cause water ingress and damage to the circuit board during the long rainy season; in addition, when the heat dissipation is insufficient, a liquid cooling device needs to be added for use.

[0019] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0020] 1. The present invention can realize the rapid installation of the communication box mechanism by setting a matching mechanism, an installation mechanism, an air-cooling component, a liquid-cooling component and an auxiliary mechanism. After installation, multi-state heat dissipation operations can be performed according to needs without disassembly. Different heat dissipation operations can be performed on the components required for installation according to seasonal conditions, and the utilization rate of each component can be improved while reducing energy consumption. In addition, the installation and disassembly of each component are relatively simple and easy to operate.

[0021] 2. The present invention sets a matching mechanism and an installation mechanism. When installing the communication box mechanism, it is only necessary to sleeve the communication circuit board on the side of the installation block, place the protective cover inside the installation cavity, and complete the installation of the protective cover and the communication circuit board only by threading the fixing rod inside the fixing groove. The installation column also serves as a limit for the communication circuit board, so that the communication box mechanism can be quickly installed. In addition, the heat sink can be installed or not installed according to needs to adapt to different heat dissipation states and improve the heat dissipation effect.

[0022] 3. The present invention sets a matching mechanism, an air-cooling component and an auxiliary mechanism. In autumn and winter, the heat sink is not installed. The second connecting groove and the third connecting groove are in corresponding positions. The first connecting groove at each position is adjusted by the adjusting rod. The first connecting groove at the upper side of the protective cover is rotated 180 degrees to connect the horizontal third connecting groove. The first connecting groove at the lower side of the protective cover is in a default state. The external airflow enters the air guide cavity through the fourth connecting groove at the upper side of the protective cover and is discharged into the third connecting groove. The upper airflow is in a convection state. The airflow is discharged from the corresponding fourth connecting groove from the third connecting groove at the lower side of the protective cover through the air guide cavity. At this time, only the assembly plate is installed to set the fan inside the protective cover. The fan outlet works downward to further guide the airflow. In this way, only air cooling and heat dissipation operations can meet the heat dissipation requirements. The unused liquid cooling heat dissipation device can perform liquid cooling and heat dissipation on other high-heat components, making full use of limited resources.

[0023] In addition, during the rainy season, the first connecting groove inside the air-cooling assembly at each group of mounting mechanisms is rotated 90 degrees so that the fourth connecting groove is not connected to the air guide cavity, thereby preventing rainwater from entering the protective cover and causing damage. These adjustments can be completed without removing the protective cover and the communication circuit board, making them easy to use.

[0024] 4. The present invention sets a matching mechanism, a liquid cooling component and an auxiliary mechanism. In spring and summer, the heat sink is installed inside the matching cavity. The movable rod is pressed to fit the side of the limit block and rotated to slide out of the slot to the inside of the guide cavity, which plays a limiting and fixing role for the heat sink. The heat sink with a liquid-cooled heat sink is installed at the side position of the protective cover through a locking rod, and then the connectors connected to the coolant pipes are respectively installed in the active cavity corresponding to the threads. The liquid-cooled heat sink circulates the coolant, so that the coolant passes through the active cavity and the connecting cavity and then flows into the guide cavity to take away the heat. The heat sink absorbs the heat from the side of the communication circuit board to complete liquid cooling. In this way, the heat dissipation requirements can be met even in high temperature weather.

[0025] 5. The present invention sets an air cooling component and a liquid cooling component. When the air cooling dissipates heat, the connector that is not connected to the coolant pipe is threadedly installed inside the movable cavity. The connector squeezes the movable rod to slide out of the connecting cavity so that the connecting cavity and the movable cavity are connected. When the fan is working, the airflow can be guided from the movable cavity and the connecting cavity at the upper side of the protective cover to the inside of the fixed groove, and then flows from the slot to the other side of the communication circuit board, and flows from the slot at the lower side of the corresponding protective cover to the connecting cavity and the movable cavity for discharge. In this way, the air cooling is further assisted to dissipate heat to the communication circuit board, and the heat dissipation efficiency is improved;

[0026] During liquid cooling, the fan can also be operated to perform air-cooled auxiliary heat dissipation operations as needed, and when the airflow passes through the air guide cavity, it can also assist in cooling the coolant flowing through the active cavity, thereby also ensuring improved heat dissipation efficiency.

[0027] 6. The present invention provides an assembly plate, a heat dissipation cover and a locking rod, etc., so that the assembly plate and the heat dissipation cover can be quickly installed and disassembled through the locking rod according to needs, so that when switching the heat dissipation mode, there is no need to disassemble the protective cover and the communication circuit board, which is more convenient to use.

[0044] The communication box mechanism 1 provided constitutes the overall structure of the communication device;

[0045] like Figures 1 to 3 As shown, the communication box mechanism 1 includes a fixing plate 11, which is a rectangular plate.

A communication circuit board 15 is provided inside the protective cover 14 and the communication circuit board 15 is attached to the inner wall of the mounting cavity 12. The communication circuit board 15 is a rectangular electronic circuit board integrated with electronic components; specifically, the communication circuit board 15 is attached to the inner wall of the mounting cavity 12, and the matching cavity 13 makes the communication circuit board 15 suspended inside the protective cover 14, which is convenient for heat dissipation of the communication circuit board 15;

[0046] The matching mechanism 2 can assist in installing and fixing the protective cover 14 and the communication circuit board 15. In addition, the matching mechanism 2 can assist in heat dissipation of the communication circuit board 15.

[0047] As shown in the figure, the matching mechanism 2 and the auxiliary mechanism 6 to Figure 8As shown, the matching mechanism 2 includes a mounting block 21 symmetrically fixedly mounted at the four corners of the inner wall of the matching cavity 13, and the communication circuit board 15 is movably sleeved on the side of the mounting block 21. The mounting block 21 is a convex rectangular block, and a fixing groove 22 is opened on the side of the mounting block 21. The fixing groove 22 is a cylindrical threaded groove.

Specifically, the communication circuit board 15 can be sleeved on the side of the mounting block 21 to cooperate with subsequent components for fixing. When air cooling is used for heat dissipation, the heat sink 23 can be installed without installing the heat sink 23 so that the communication circuit board 15 is semi-suspended.

[0048] The provided mounting mechanism 3 can be used for quick mounting of the protective cover 14 and the communication circuit board 15;

[0049] like Figures 3 to 6 and Figures 9 to 11 As shown, the mounting mechanism 3 includes a mounting column 31 fixedly mounted on the inner side of the protective cover 14 and the mounting column 31 is attached to the side position of the communication circuit board 15. The mounting column 31 is a rectangular column with a cylindrical groove on the side. A fixing rod 32 is movably mounted inside the mounting column 31 and the fixing rod 32 penetrates the protective cover 14 and is threadedly mounted inside the fixing groove 22. The fixing rod 32 is a "T"-shaped cylindrical rod with a threaded portion at the protrusion. A connecting cavity 33 penetrating the fixing rod 32 is provided on the side of the fixing rod 32, and the cross-section of the cylindrical cavity is cross-shaped. Specifically, after the communication circuit board 15 and the protective cover 14 are placed respectively, it is only necessary to thread the fixing rod 32 inside the fixing groove 22. The fixing rod 32 fixes the protective cover 14, and the mounting column 31 can fix the communication circuit board 15.

[0050] like Figures 3 to 6 and Fig.12 As shown, an air cooling component 4 with adjustable air cooling and heat dissipation and a liquid cooling component 5 with adjustable liquid cooling and heat dissipation are arranged inside the connecting cavity 33;

[0051] like Figure 6 and Figures 9 to 12As shown, the air cooling component 4 includes an adjusting rod 41 movably installed in the connecting cavity 33, and the adjusting rod 41 extends out of the internal position of the connecting cavity 33. The adjusting rod 41 is a cylindrical rod with a "C"-shaped cross section. A return spring 42 is fixedly connected to the side of the adjusting rod 41 and the return spring 42 is movably sleeved on the side of the adjusting rod 41. The return spring 42 only fits the inner wall of the adjusting rod 41 but is not fixed thereto. A card slot 43 is equidistantly provided on the side of the fixed rod 32. The card slot 43 is a rectangular slot. A card block 44 is fixedly installed on the side of the adjusting rod 41 close to the fixed rod 32, and the card block 44 is carded in the internal position of the card slot 43. The card block 44 is a rectangular block. An air guide cavity 45 is provided inside the adjusting rod 41. The air guide cavity 45 is a circular cavity. First connecting grooves 46 that penetrate the adjusting rod 41 are equidistantly provided on the inner wall of the air guide cavity 45, and the first connecting grooves 46 are arranged in a "T" shape. A second connecting groove 47 penetrating the fixing rod 32 is provided on the side of the mounting column 31 at a position corresponding to the first connecting groove 46, and a third connecting groove 48 penetrating the mounting column 31 is provided on the side of the mounting column 31 at a position corresponding to the second connecting groove 47. The first connecting groove 46, the second connecting groove 47 and the third connecting groove 48 are rectangular grooves and are in a linear corresponding state. A fourth connecting groove 49 penetrating therethrough is provided on the side of the protective cover 14 at a position corresponding to a group of third connecting grooves 48, and the fourth connecting groove 49 is a rectangular groove with a funnel-shaped cross section; the adjusting rod 41 is pulled to make the clamping block 44 disengage from the inside of the clamping groove 43, the reset spring 42 is squeezed and deformed by the adjusting rod 41, the adjusting rod 41 is rotated to make the first connecting groove 46 and the second connecting groove 47 positions staggered into different states, and the adjusting rod 41 is released so that the clamping block 44 is clamped in the corresponding clamping groove 43 to fix the adjusting rod 41 under the deformation force of the reset spring 42;

[0052] The liquid cooling component 5 includes a movable cavity 51 penetrating through the side surface of the adjusting rod 41, and the movable cavity 51 corresponds to the connection cavity 33. The movable cavity 51 is a cylindrical cavity. An activity rod 52 is movably installed inside the movable cavity 51, and the activity rod 52 extends to the inside position of the fixed groove 22. The activity rod 52 is a cylindrical rod with a cross-section in the shape of a Chinese character "tu". A matching block 53 is movably sleeved on the side surface of the activity rod 52 away from the limit block 26. The matching block 53 is an "L"-shaped circular ring block with fan-shaped blocks equidistantly arranged on its side surface. Stirring blocks 54 are fixedly installed on the side surface of the activity rod 52 at equal intervals. The stirring blocks 54 are arc-shaped fan blade blocks. A fixed block 55 is fixedly installed on the inner wall of the connection cavity 33, and the fixed block 55 is movably sleeved on the side surface of the activity rod 52. The fixed block 55 is a circular ring block with fan-shaped grooves equidistantly arranged on its side surface. A support cylinder 56 is fixedly installed on the side surface of the fixed block 55, and the support cylinder 56 is movably sleeved on the side surface of the activity rod 52. The support cylinder 56 only fits on the side surface of the activity rod 52 without being fixed to it. Specifically, in the default state, under the elastic support of the support cylinder 56, the activity rod 52 completely slides into the connection cavity 33, and the activity rod 52 blocks the connection cavity 33, and the matching block 53 slides inside the movable cavity 51 to play a guiding role. By pressing the activity rod 52 with a tool to make it slide out of the connection cavity 33, the activity rod 52 fits on the side surface of the limit block 26, and rotating the activity rod 52 drives the limit block 26 to slide out of the slot 25 into the diversion cavity 24, completing the clamping operation of the limit block 26 on the heat dissipation plate 23. When the subsequent components squeeze the side surface of the matching block 53, the activity rod 52 slides out of the connection cavity 33 and does not contact the limit block 26, connecting the connection cavity 33 and the movable cavity 51. When the coolant passes through, the matching block 53 is fixed under extrusion, and the stirring block 54 is impacted to make the activity rod 52 rotate with the matching block 53 and the fixed block 55 as supports to play a stirring role.

[0053] The auxiliary mechanism 6 provided can be used in combination with the installation of appropriate components according to the heat dissipation requirements.

[0054] As Figure 1 、 Figure 3 、 Fig. 9 and Fig.12 shown, the auxiliary mechanism 6 includes an assembly plate 61 provided on the side surface of the protective cover 14, and the assembly plate 61 penetrates through the protective cover 14 to its inside. The assembly plate 61 is a convex-shaped rectangular plate. A blower 62 is fixedly installed on the side surface of the assembly plate 61 corresponding to the inside of the protective cover 14. Locking rods 63 are provided at the four corners of the assembly plate 61, and the locking rods 63 are threadedly installed on the side surface of the protective cover 14. Specifically, the assembly plate 61 can be fixedly installed on the side surface of the protective cover 14 through the provided locking rods 63. At this time, only the blower 62 is installed, and the communication circuit board 15 can be cooled by air.

[0055] A heat dissipation cover 64 is provided on the side of the assembly plate 61, and the heat dissipation cover 64 can also be fixedly installed at the side position of the protective cover 14 through a locking rod 63. The heat dissipation cover 64 is a convex cover with a hollow side and circular holes are opened at equal intervals on the side. A liquid cooling device 65 is symmetrically fixedly installed on the inner side of the heat dissipation cover 64. The liquid cooling device 65 is composed of a water pump, a cooling fan, and a heat dissipation pipe, etc., which can circulate the coolant while performing heat dissipation and cooling operations on it. A cooling liquid pipe 66 that runs through the heat dissipation cover 64 is fixedly connected to the water inlet and the water outlet of the liquid cooling device 65, respectively. The cooling liquid pipe 66 is a circular pipe. A connector 67 is fixedly installed at one end of the cooling liquid pipe 66 away from the liquid cooling device 65, and the connector 67 is threadedly installed in the active cavity 51. Internally, the connector 67 fits against the side of the matching block 53 to squeeze it, and after the fan 62 and the liquid cooling heat sink 65 are installed, the circuit installation can be carried out to connect the power supply; specifically, after the connector 67 is installed, the matching block 53 of the frame allows the movable rod 52 to slide out of the connecting cavity 33, and the connecting cavity 33 and the movable cavity 51 are connected. The cooling liquid is passed from the movable cavity 51 and the connecting cavity 33 to the inside of the fixed groove 22 through the cooling liquid pipe 66 at the water outlet of the liquid cooling heat sink 65, and then flows from the fixed groove 22 to the inside of the guide cavity 24 to take away the heat of the heat sink 23. Similarly, the cooling liquid is drawn back from the corresponding fixed groove 22 to the connecting cavity 33 and the movable cavity 51 through the cooling liquid pipe 66 at the water inlet of the liquid cooling heat sink 65, forming a cooling liquid circulation, and the communication circuit board 15 can be liquid cooled.

[0056] Working principle:

[0057] Before use: Determine the required heat dissipation requirements according to the season and install the required components for use;

[0058] When in use: in autumn and winter, when the temperature is generally not high, the heat sink 23 is not installed at this time, and the fixing rod 32 is threadedly installed inside the fixing groove 22 to complete the fixing and installation of the corresponding protective cover 14 and the communication circuit board 15. At this time, the second connecting groove 47 and the third connecting groove 48 are in corresponding positions. After the adjusting rod 41 is pulled to disengage the card block 44 from the card slot 43 and then rotated to adjust the position, the adjusting rod 41 is released to reset the card block 44 and connect it to the card slot 43. At this time, the first connecting groove 46 and the second connecting groove 47 are in staggered different states. The first connecting groove 46 inside the air-cooling component 4 at the upper side of the protective cover 14 is rotated 180 degrees to connect the horizontal third connecting groove 48, and the first connecting groove 46 inside the air-cooling component 4 at the lower side of the protective cover 14 is rotated 180 degrees to connect the horizontal third connecting groove 48. The connecting slot 46 is in the default state. At this time, the external wind flow can enter the air guide cavity 45 through the fourth connecting slot 49 at the upper side of the protective cover 14. The air flow inside the air guide cavity 45 is discharged into the third connecting slot 48. The upper air flow is in a convection state. The wind flow is discharged from the corresponding fourth connecting slot 49 through the air guide cavity 45 from the third connecting slot 48 at the lower side of the protective cover 14. At this time, only the assembly plate 61 is installed to set the fan 62 on the inner side of the protective cover 14. The air outlet of the fan 62 works downward to further guide the air flow. In the rainy season, the first connecting slot 46 inside the air cooling component 4 at the position of each group of mounting mechanisms 3 is rotated ninety degrees, so that the fourth connecting slot 49 is not connected with the air guide cavity 45, so as to prevent rainwater from entering the protective cover 14 and causing damage.

[0059] Furthermore, the connector 67 not connected to the coolant pipe 66 can be threadedly installed inside the active cavity 51, and the connector 67 squeezes the active rod 52 to slide out of the connecting cavity 33 so that the connecting cavity 33 and the active cavity 51 are connected. When the fan 62 is working, the airflow can be guided from the active cavity 51 and the connecting cavity 33 at the upper side of the protective cover 14 to the inside of the fixed groove 22, and then flow from the slot 25 to the other side of the communication circuit board 15, and flow from the slot 25 at the lower side of the corresponding protective cover 14 to the connecting cavity 33 and the active cavity 51 for discharge, so as to further assist the air cooling to dissipate the heat of the communication circuit board 15;

[0060] In spring and summer, when the weather temperature is generally high, the heat sink 23 is installed inside the matching cavity 13, and the protective cover 14 and the communication circuit board 15 are fixed by the fixing rod 32. The movable rod 52 is pressed by a tool to fit the side of the limit block 26, and the movable rod 52 is rotated to make the limit block 26 slide out of the slot 25 to the inside of the guide cavity 24, so as to limit and fix the heat sink 23. At the same time, the heat sink 64 with the liquid cooling heat sink 65 is installed at the side position of the protective cover 14 through the locking rod 63, and then the connector 67 connecting the coolant pipe 66 is respectively installed in the active cavity 51 corresponding to the thread. The coolant is circulated and pumped by the liquid cooling heat sink 65, so that the coolant passes through the active cavity 51 and the connecting cavity 33 and then flows into the guide cavity 24 to take away the heat. The heat sink 23 absorbs the heat from the side of the communication circuit board 15 to complete the liquid cooling heat dissipation. At this time, the fan 62 can also perform air-cooled auxiliary heat dissipation operation according to the needs, wherein the airflow can also assist the cooling operation of the coolant flowing through the inside of the active cavity 51 when passing through the air guide cavity 45.

[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
