Description

Technical Field

[0001] The invention belongs to the technical field of electronic component heat dissipation, and in particular relates to a quick-detachable expandable water cooling radiator. Background Art

[0002] Water cooling refers to a method of heat dissipation that removes heat from high-temperature components through the circulation of water-cooling liquid. Since the specific heat capacity of water is much greater than that of air, water cooling can transfer more heat faster. At the same time, freely arranged water-cooling pipes can integrate the heat dissipation needs of the main heat-generating components in the equipment, making it convenient for users to uniformly manage the heat dissipation of the equipment from a system level.

[0003] A radiator is a device used to lower the temperature of the coolant. It is generally composed of pipes and fins brazed on the pipes. A fan blows air through the fins to lower the temperature of the coolant. In the entire water cooling system, it is mainly responsible for discharging heat from the system. For an air-cooled system, it is generally necessary to install the cooling fins near the heating elements. The installation position of the radiator is flexible, and the appropriate size of the radiator can be selected according to the system load.

[0004] During the water cooling system selection process in the product design stage, designers need to calculate the required area of ​​the water cooling radiator based on the heat generation power of each heating element. Water cooling radiator suppliers also need to provide water cooling radiators of different specifications for selection. This requires suppliers to maintain production lines of multiple models, increasing the company's operating costs.

[0005] In recent years, with the improvement of the electronic level of products, more and more devices need to consider heat dissipation for their electronic equipment. The modular water cooling radiator has received more and more attention due to its excellent scalability. Although the commonly used modular water cooling radiator can be applied to different heat loads, the disassembly and assembly process is complicated, and the water cooling liquid in the water cooling system needs to be drained when disassembling the water cooling radiator to prevent water cooling liquid leakage during the disassembly and assembly process. Therefore, it is necessary to design a modular water cooling radiator that can achieve quick disassembly and assembly functions and prevent leakage during the disassembly and assembly process.

DETAILED DESCRIPTION

[0033] The present invention will be described in detail below according to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become more clear. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] like Figure 1 As shown, a quick-detachable expandable water-cooling radiator includes an upper joint 1, a water-cooling pipeline 2, heat dissipation fins 3, a main body bracket 4, and a lower joint 6.

[0035] The heat sink fin 3 is installed in the middle of the main frame 4, and there are two upper joints 1 and two lower joints 6, which are respectively installed at the four corners of the main frame 4, and the two upper joints 1 are located on one diagonal line of the main frame 4, and the two lower joints 6 are located on the other diagonal line of the main frame 4. The upper joint 1 and the lower joint 6 on the same side are connected through the water cooling pipeline 2, and the water cooling pipeline 2 passes through the heat sink fin 3 at the same time.

[0036] like Figure 2 As shown, a quick-detachable expandable water-cooling radiator can be connected in series with another quick-detachable expandable water-cooling radiator through its upper joint 1 and lower joint 6 located on one side to complete the expansion of the water-cooling radiator.

[0037] like Figure 3 and 4 As shown, the upper joint 1 includes a gland 5, a knob 7, a cylindrical head 8, a bolt 9, an upper joint housing 10, a fixing screw 11, a gasket 12, an upper spring 13, an upper sealing ring 14, and an upper plug 15.

[0038] The lower joint 2 includes a lower sealing ring 16 , a lower plug 17 , a lower spring 18 , a sealing plug 19 , a sealing gasket 20 , and a lower joint housing 21 .

[0039] The bottom of the upper joint housing 10 has an annular protrusion, and the upper end of the lower joint housing 21 has an annular groove. The annular protrusion and the annular groove cooperate to achieve the positioning of the upper joint housing 10 and the lower joint housing 21, ensuring that the threaded holes of the upper and lower joints and the interface with the water cooling pipeline 2 are aligned; a sealing gasket 20 is installed in the annular groove, which can effectively prevent the leakage of water cooling liquid after the housing is compressed. The upper end face of the upper joint housing 10 is provided with a threaded through hole, and the upper end face of the lower joint housing 21 is provided with a threaded hole, and the bolt 9 can pass through the threaded through hole of the upper joint housing 10 and the threaded hole of the lower joint housing 21 to fix the upper joint 1 and the lower joint 2 together.

[0040] A stepped through hole is provided at the center of the upper joint housing 10, and the stepped through hole includes a threaded hole, a regular octagonal through hole, a cylindrical hole, and a conical hole from top to bottom. The cylindrical hole in the stepped through hole is connected to the water cooling pipe 2. The knob 7 is installed in the stepped through hole of the upper joint housing 10, and the axial limit is achieved by the step. The knob 7 is fixed to the upper joint housing 10 by installing a gland 5 on the outside. There is a cylindrical through hole inside the knob 7, and a cylindrical head 8 with the same diameter as the through hole is fixedly installed at the upper end of the through hole by threading, and there are two raised support sliders 22 at the bottom of the through hole.

[0041] The upper plug 15 is a truncated cone, which is installed in the stepped through hole at the center of the upper joint housing 10, and the mating surfaces of the two are sealed by a sealing ring 14. The inclination angle of the bevel of the upper plug 15 is the same as the inclination angle of the bevel of the tapered hole of the stepped through hole of the upper joint housing 10. A regular octagonal shell is extended from the upper end of the upper plug 15, and a fixed cylinder 23 with a double helical groove is provided in the center of the regular octagonal shell. The lower end of the knob 7 is inserted into the regular octagonal shell, and the fixed cylinder 23 with a double helical groove is inserted into the cylindrical through hole inside the knob 7 to achieve double-layer nesting. The regular octagonal shell cooperates with the regular octagonal through hole of the upper joint housing 10 so that the upper plug 15 can only move axially. The support slider 22 of the cylindrical through hole inside the knob 7 cooperates with the double-threaded groove on the fixed cylinder 23 with the double helical groove, so that when the knob 7 rotates, due to the cooperation of the two, the upper plug 15 moves downward in the axial direction.

[0042] An upper spring 13 is sleeved on the fixed cylinder 23 with a double helical groove of the upper plug 15, and the lower end of the upper spring 13 is limited by a supporting slider 22 inside the knob 7, and the upper end of the upper spring 13 is fixed to the fixed cylinder 23 with a double helical groove by a gasket 12 and a fastening screw 11.

[0043] A stepped through hole is provided at the center of the lower joint housing 21, and the stepped through hole includes a tapered hole, a cylindrical hole, and a threaded hole from top to bottom. The cylindrical hole in the stepped through hole is connected to the water-cooling pipe 2. The lower plug 17 is a truncated cone, and the lower plug 17 is installed in the stepped through hole in the center of the lower joint housing 21, and the mating surfaces of the two are sealed by the lower sealing ring 16. The inclination angle of the bevel of the lower plug 17 is the same as the inclination angle of the bevel of the tapered hole of the stepped through hole of the lower joint housing 21. The inclination angles of the bevels of the two truncated cones of the upper plug 15 and the lower plug 17 are the same, and the bottom surface of the upper plug 15 is completely fitted with the top surface of the lower plug 17, so that the upper plug 15 and the lower plug 17 can move axially together when mating.

[0044] A sealing plug 19 having the same diameter as the threaded hole is fixedly installed in the threaded hole of the stepped through hole of the lower joint housing 21 by means of threads to play a sealing role.

[0045] A regular octagonal shell extends from the bottom surface of the lower plug 17, and a regular octagonal deep hole is provided at the center of the upper end of the sealing plug 19, and a cylinder is provided in the deep hole; the regular octagonal shell of the lower plug 17 is inserted into the regular octagonal deep hole of the sealing plug, and the two cooperate so that the lower plug 17 can only move axially; the upper end of the lower spring 18 abuts against the bottom surface of the lower plug 17, and the lower end of the lower spring 18 abuts against the cylinder in the regular octagonal deep hole of the sealing plug 19.

[0046] When the knob 7 is not rotated, the upper plug 15 and the lower plug 17 are pressed against each other by the upper spring 13 and the lower spring 18, and the sealing rings and the conical holes on the upper and lower plugs are cooperated to ensure the sealing of the upper and lower joints and prevent the circulation of water coolant.

[0047] When the knob 7 is rotated forward, since the knob 7 is axially fixed by the pressure cover 5, the protruding supporting slider 22 at the bottom of the knob 7 rotates along the fixed cylinder 23 with double spiral grooves of the upper plug 15, so that the upper plug 15 overcomes the supporting force of the upper spring 13 and moves downward. Since the upper plug 15 and the lower plug 17 are in close contact, the upper plug 15 pushes the lower plug 17 to move downward together. At this time, the upper and lower joints are connected to the cylindrical holes connected to the water-cooling pipeline 2, the water-cooling pipeline 2 of the water-cooling radiator is normally connected, and the water-cooling radiator can be used normally.

[0048] When the knob 7 is rotated in the reverse direction, the support slider 22 of the knob 7 rotates in the reverse direction along the fixed cylinder 23 with double spiral grooves of the upper plug 15. At this time, the upper plug 15 and the lower plug 17 move upward under the action of the upper spring 13 and the lower spring 18 to seal the water cooling pipe 2 of the water cooling radiator. The upper plug 15 of the upper joint is in close contact with the lower plug 17 of the lower joint, so there will be no water cooling liquid leakage during the installation and removal process.

[0049] The water cooling radiator is generally installed in the heat dissipation air duct of the electronic equipment, and the fan in the air duct forms a heat dissipation airflow. In the quick-detachable expandable water cooling radiator of the present invention, the main frame 4 shields the gap except the heat dissipation fins 3, so that the heat dissipation airflow only passes through the heat dissipation fins 3 and removes the heat through the water cooling liquid, thereby achieving the purpose of reducing the airflow temperature.

[0050] When a single quick-detachable expandable water-cooling radiator is in use, the coolant enters the water-cooling pipe 2 from the upper joint 1 or the lower joint 6 on one side through an external joint, then flows through the pipe in the heat sink 3 to the water-cooling pipe 2 on the other side, and flows out from the upper joint 1 or the lower joint 6 on a side that is not the same as the water inlet through the external joint.

[0051] When multiple quick-release expandable water-cooling radiators are used in combination, first align the upper and lower joints of the two quick-release expandable water-cooling radiators so that the annular protrusion of the upper joint shell 10 and the annular groove of the lower joint shell 21 are matched to complete the positioning; rotate the bolt 9 of the upper joint 1 forward to quickly complete the tight connection of the two quick-release expandable water-cooling radiators. When the knob 7 is not rotated, the upper plug 15 is in close contact with the lower plug 17 under the action of the upper spring 13 and the lower spring 18. Rotate the knob 7 of the upper joint 1 forward, and the water-cooling pipeline 2 between the two quick-release expandable water-cooling radiators is connected, and the water-cooling heat dissipation system can operate normally. After the water-cooling liquid enters the water-cooling pipeline 2 from the upper joint 1 or the lower joint 6 of the first quick-release expandable water-cooling radiator through the external joint, the water-cooling pipelines 2 are connected through the cooperation of the upper and lower joints, and the water-cooling liquid flows in the connected water-cooling pipeline 2 and the pipeline in the heat dissipation fins 3, and finally flows out from the upper joint 1 or the lower joint 6 on the same side as the water inlet through the external interface. When removing, first reversely rotate the knob 7 of the upper joint 1 to disconnect the water cooling pipes 2 between the two adjacent quick-release expandable water cooling rows, and then reversely rotate the bolt 9 of the upper joint 1 to quickly disconnect the connection between the quick-release expandable water cooling rows, and there will be no water cooling liquid leakage during the installation and removal process.

Although the invention is described in detail with reference to the above examples, those skilled in the art can still modify the technical solutions recorded in the above examples or replace some of the technical features therein with equivalents.
