Description

Technical Field

[0001] The utility model relates to the technical field of radiators, and particularly relates to a water block and a water-cooled radiator adopting a metal pressing plate. Background Art

[0002] Electronic components generate heat during operation. In recent years, with the gradual improvement of the performance of computer systems, the heat generated by electronic components such as CPUs due to operation has inevitably increased. To solve the problem of their heat generation, a heat dissipation system is usually required to quickly dissipate heat to prevent the electronic components from reducing their lifespan or being damaged due to overheating.

[0003] Currently, the mature heat dissipation methods include air cooling and liquid cooling. The chip liquid-cooled radiator has the advantages of being quiet, having stable temperature reduction, and being less dependent on the environment. The traditional liquid-cooled radiator consists of three parts: a water block, a radiator, and a fan. Among them, the water block is directly in contact with the chip and is responsible for absorbing the heat dissipated by the chip. The water pump in the water block is responsible for providing the power for the flow of the coolant. After the coolant absorbs heat in the water block, it flows into the radiator through the water pipe under the action of the water pump; the radiator is installed in the chassis and is responsible for dissipating the heat absorbed by the coolant outside the chassis. After the coolant is cooled in the radiator, it flows back to the water block through the water pipe, and this cycle continues; the fan is installed on the radiator and is responsible for accelerating the air flow speed in the radiator to improve the heat dissipation efficiency.

[0004] However, existing products usually use self-tapping screws to lock the water block on the plastic base, and then fix the plastic base in the chassis through mounting fasteners, so that the water-cooling block of the water block is fixed above the chip and in contact with the chip to absorb the heat generated during the operation of the chip. This fixing method usually causes the plastic part to be stressed and is prone to breakage, resulting in the displacement of the water block and affecting the heat dissipation efficiency.

In addition, the terms such as the first and the second are only used to distinguish multiple components or structures with the same or similar structures, and do not represent a special limitation on the setting order or connection relationship.

[0033] This embodiment relates to a water-cooled head using a metal pressing plate. Referring to Figure 1 - Figure 6 , it includes a cold head body 10, a water-cooling block 20, a metal pressing plate 30, and a mounting buckle assembly 40. Among them, the cold head body 10 includes a cold head base 11 and a water-cooling assembly provided on the cold head base 11. A water-cooling liquid cavity 111 for storing water-cooling liquid is formed by the cooperation between the cold head base 11 and the water pump assembly 12. The water-cooling block 20 is arranged on the bottom side of the cold head base 11 and is used to contact the chip to absorb the heat dissipated by the chip. The water pump assembly 12 has a liquid inlet pipe 121 and a liquid outlet pipe 122. The water-cooling liquid in the water-cooling liquid cavity 111 is sent out and refluxed through the water pump assembly 12 to realize the circulation use of the water-cooling liquid, thereby realizing the continuous heat dissipation of the chip.

[0034] The metal pressing plate 30 is arranged on the cold head base 11. A perforation for the water pump assembly 12 to pass through is provided in the middle of the metal pressing plate 30, so that the metal pressing plate 30 can contact the upper surface of the cold head base 11. The metal pressing plate 30 is fixedly connected to both the water-cooling block 20 and the cold head base 11 to improve the assembly stability of the cold head body 10 and the water-cooling block 20.

[0035] The mounting buckle assembly 40 is arranged on the bottom side of the metal pressing plate 30, and its edge is exposed outside the metal pressing plate 30.

[0036] In addition, the water block using the metal pressing plate 30 provided in this embodiment further includes a fastener 50, which is used to cooperate with the mounting buckle assembly 40 to fix the metal pressing plate 30 (fixed inside the chassis or on the circuit board), so that the water block 20 can stably contact the chip, thereby enabling the water block 20 to stably absorb the heat dissipated by the chip.

[0037] It can be understood that by fixing the metal pressing plate 30 on the cold head base 11 and fixedly connecting the metal pressing plate 30 to the water block 20, the assembly between the cold head base 11 and the water block 20 is stable and reliable. At the same time, an installation space is provided for the mounting buckle assembly 40. The metal pressing plate 30 is fixed by the fastener 50 and the mounting buckle assembly 40, so that the water block 20 can stably contact the chip and absorb the heat dissipated by the chip, avoiding the phenomenon of thread slipping and breaking caused by using a plastic base in the traditional method, and ensuring the stability of the water block.

[0038] Furthermore, the water block 20, the cold head body 10 and the metal pressing plate 30, and between the mounting buckle assembly 40 and the metal pressing plate 30 are all fixedly connected by threaded parts 60. In this embodiment, the threaded parts 60 are screws or bolts. In the specific implementation process, a set of screws can be used to lock the water block 20, the cold head body 10 and the metal pressing plate 30 together, and another set of screws can be used to lock the mounting buckle assembly 40 on the metal pressing plate 30, thereby improving the assembly stability among the water block 20, the cold head base 11, the metal pressing plate 30 and the mounting buckle assembly 40.

[0039] Furthermore, the mounting buckle assembly 40 includes two mounting buckle bodies 41 arranged oppositely. The two mounting buckle bodies 41 are respectively arranged on both sides of the bottom of the metal pressing plate 30. The edges of the two mounting buckle bodies 41 are exposed outside the metal pressing plate 30. The water block 20 is located inside the two mounting buckle bodies 41, and the bottom side of the water block 20 protrudes from the mounting buckle bodies 41.

[0040] The mounting buckle body 41 is generally arranged in a long strip shape. One side of the mounting buckle body 41 is located at the bottom side of the metal pressing plate 30, and the other side of the mounting buckle body 41 is exposed outside the metal pressing plate 30. The two ends of the mounting buckle body 41 extend obliquely outward, so that when the two mounting buckle bodies 41 are locked on the metal pressing plate 30, the edges of the mounting buckle body 41 can be exposed outside the metal pressing plate 30, thereby providing an installation position for the fastener 50.

[0041] Furthermore, the fastener 50 includes a through hole 51 opened on the mounting buckle body 41 and a screw rod 52 passing through the through hole 51. The through hole 51 is located at the end of the mounting buckle body 41 on the side exposed outside the metal pressing plate 30, and external threads are provided on the screw rod 52.

[0042] By passing the screw rod 52 through the through hole 51 of the mounting buckle body 41 and matching the thread on the screw rod 52 with the threaded hole in the chassis, the fixing of the mounting buckle body 41 is realized, that is, the fixing of the metal pressing plate 30 is realized, and further the fixing of the entire water-cooled head is realized, so that the water-cooling block 20 can stably contact the chip and absorb the heat dissipated by the chip, ensuring the heat dissipation efficiency of the chip.

[0043] Further, referring to Figure 4 and Figure 5 , the screw rod 52 includes a first rod portion 521 and a second rod portion 522. The first rod portion 521 is located above the second rod portion 522. The first rod portion 521 and the second rod portion 522 are integrally formed. There is a groove 523 between the first rod portion 521 and the second rod portion 522. A convex piece 511 matching the groove 523 is arranged in the through hole 51. The convex piece 511 is made of elastic material. A spring 524 is arranged between the first rod portion 521 and the mounting buckle body 41, and an external thread is arranged on the second rod portion 522.

[0044] It can be understood that when fixing the mounting buckle body 41, by passing the screw rod 52 through the through hole 51, that is, passing the second rod portion 522 through the through hole 51, the convex piece 511 in the through hole 51 abuts against the groove 523 between the first rod portion 521 and the second rod portion 522, so as to realize the limitation of the position of the first rod portion 521. When the screw rod 52 is locked, the spring 524 can continuously provide elastic force to the screw rod 52, thus playing the role of shock absorption and locking.

[0045] Further, referring to Figure 4 and Figure 6 , a diversion port 112 communicating with the water-cooling liquid cavity 111 is opened on the cold head base 11. The water-cooling block 20 is located at the diversion port 112, and the water-cooling block 20 is used to close the water-cooling liquid cavity 111. During use, the water-cooling block 20 is abutted against the bottom side of the cold head base 11, and the water-cooling liquid cavity 111 is closed by the water-cooling block 20, so that the water-cooling liquid in the water-cooling liquid cavity 111 is not easy to leak. At the same time, the heat absorbed by the water-cooling block 20 will be transferred to the water-cooling liquid, realizing the transfer of heat. At this time, the water-cooling liquid is pumped out of the water-cooled head by the water pump assembly 12 for heat dissipation and then flows back into the water-cooling liquid cavity 111, so as to realize the recycling of the water-cooling liquid and further realize the continuous heat dissipation of the chip.

[0046] Further, a sealing ring 114 is arranged between the cold head base 11 and the water-cooling block 20. A sealing groove 113 for accommodating the sealing ring 114 is opened on the cold head base 11. The sealing groove 113 is located outside the diversion port 112, and the sealing groove 113 and the sealing ring 114 cooperate to block the gap between the cold head base 11 and the water-cooling block 20.

[0047] It can be understood that through the cooperation between the sealing groove 113 and the sealing ring 114, the gap between the cold head base 11 and the water cooling block 20 is sealed, thereby ensuring the sealing performance between the water cooling block 20 and the cold head base 11 and avoiding the leakage of the water cooling liquid.

[0048] Furthermore, the sealing groove 113 has a plurality of arc grooves, and the plurality of arc grooves are evenly distributed on the inner side of the sealing groove 113. The sealing ring 114 is adapted to the shape of the sealing groove 113 and fits tightly.

[0049] Through the setting of the arc grooves, the entire sealing groove 113 and the sealing ring 114 are not circular. In the specific implementation process, the non-circular sealing ring 114 has a better sealing effect, thereby further avoiding the risk of water cooling liquid leakage. At the same time, during the assembly process, the threaded part 60 for fixing the water cooling block 20 is passed through the arc grooves, which can further limit the position of the sealing ring 114. The sealing ring 114 is more evenly stressed, making the sealing ring 114 not easily displaced or deformed, thereby further ensuring the sealing effect of the sealing ring 114.

[0050] Furthermore, in combination Figure 1 and Figure 2 , the cold head body 10 further includes a housing 13. The housing 13 is fixedly arranged on the metal pressing plate 30, and the water pump assembly 12 and the metal pressing plate 30 are both accommodated in the housing 13.

[0051] Through the setting of the housing 13, it can protect the water pump assembly 12 and prevent external dust from entering the water pump assembly 12 and causing damage to the water pump assembly 12. Moreover, the housing 13 can also improve the overall decoration, making it more beautiful and enhancing the market competitiveness.

[0052] In addition, this embodiment also provides a water-cooled radiator, including the water-cooled head using the metal pressing plate 30 as described above.

[0053] The above is only used to illustrate the technical solution of the present invention and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
