Description

Technical Field

[0001] This invention relates to the field of heat dissipation equipment technology, and specifically to a liquid-cooled heat sink. Background Technology

[0002] With the continuous increase in the capacity of power electronic devices and the development of device integration and miniaturization, the heat flux density of power semiconductors is getting higher and higher. This causes the junction temperature inside the power semiconductor to rise sharply when the device is working, which not only affects the performance of the device and shortens its service life, but may even damage the power semiconductor and cause the device to shut down.

[0003] Existing high-power cooling generally uses tubular liquid coolers or liquid coolers with independent finned heat dissipation components welded to cold plate flow channels. By increasing the volume of the heat exchanger, increasing the flow rate of the cooling medium, or increasing the pressure drop between the inlet and outlet of the heat exchanger, the heat exchange efficiency can be improved.

[0004] Currently, there are methods to increase the flow path of the cooling medium and increase the heat exchange area by setting up a serpentine channel, thereby reducing the thermal resistance. The channel inside the liquid cooling cavity is designed in a serpentine shape to reduce the flow resistance of the liquid in the water cooling cavity. However, in the manufacturing process, it is generally done by stacking two plates together and combining them by welding or bonding. The manufacturing process is complicated, and gaps are easy to appear between the two plates, causing the cooling medium to deviate from the preset path. As a result, some of the cooling medium will stop in a certain part, resulting in insufficient replacement of the cooling medium and affecting the heat exchange effect. Summary of the Invention

[0005] The purpose of this invention is to provide a liquid-cooled radiator that allows the cooling medium to travel along a preset route while reducing processing difficulties and ensuring sufficient replacement of the cooling medium to minimize the impact on heat exchange.

The surface of the mounting block is slidably connected to the surface of the heat dissipation shell plate through an opening in the through hole. One end of the stop bolt that protrudes from the mounting block abuts against the surface of the liquid outlet pipe.

[0012] Optionally, the liquid outlet pipe includes a first channel and a second channel, with the output ends of the first channel and the second channel located at opposite ends of the liquid outlet pipe.

[0013] Optionally, the drain channel is provided with a blocking component for blocking the drain channel, and both the first channel and the second channel are provided with a clearing component.

This reduces the complexity of fabricating serpentine pipes, facilitating processing while maximizing the heat exchange area and reducing thermal resistance. Furthermore, the serpentine tube design increases the flow path of the cooling medium, resulting in more efficient utilization of the medium. The integral molding of the spacers and heat dissipation shell also effectively prevents gaps between them, ensuring the cooling medium flows along its intended path and avoids some cooling medium remaining within the heat dissipation shell due to these gaps. This would hinder the replacement of the cooling medium and ultimately affect the heat dissipation effect. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 4 The present invention provides a technical solution: a liquid-cooled radiator, comprising a support mechanism, a sealing mechanism, and a heat dissipation component; The supporting mechanism includes a heat dissipation shell plate 2 with a liquid storage cavity 1 and a spacer 3 assembly integrally formed with the heat dissipation shell plate 2. The spacer 3 assembly is located inside the liquid storage cavity 1, and the heat dissipation shell plate 2 has a plate-shaped structure with openings at both ends. The liquid storage chamber 1 is connected to the liquid inlet pipe 4 and the liquid outlet pipe 5. The liquid inlet pipe 4 is located on one side of the spacer bar 3 assembly, and the liquid outlet pipe 5 is located on the other side of the spacer bar 3 assembly. The spacer 3 assembly includes a plurality of spacers 3 spaced apart along a first direction, and a third flow channel extending along a second direction is formed between two adjacent spacers 3; The sealing mechanism includes a first sealing member detachably connected to one end of the heat sink 2 and a second sealing member at the other end. The first sealing member includes a first protrusion for insertion between two adjacent spacers 3, and the second sealing member includes a second protrusion for insertion between two adjacent spacers 3. Along the first direction, the first protrusion and the second protrusion are alternately arranged. A first flow channel is formed on the first protrusion, and a second flow channel is formed on the second protrusion; wherein, adjacent first and second flow channels are connected by corresponding third flow channels. The heat dissipation component is detachably connected to the surface of the heat dissipation shell 2 to dissipate heat from the heat dissipation shell 2, thereby improving the cooling efficiency of the heat dissipation shell 2. The connection between the heat dissipation shell plate 2 and the spacer 3 divides the liquid storage chamber 1 into multiple areas, forming a third flow channel for the cooling medium to circulate. The inlet pipe 4 connects to the cooling medium source, and the outlet pipe 5 allows the cooling medium in the liquid storage chamber 1 to be discharged. The cooling medium is a known technology and is only referenced here without further explanation. Its purpose is to assist the heat exchange of the heat dissipation shell plate 2. The sealing mechanism seals the openings at both ends of the heat dissipation shell plate 2. The connection between the first and second protrusions and the spacer 3 forms a serpentine flow channel with the spacer 3, increasing the flow path of the cooling medium and making full use of it. The heat dissipation components help dissipate heat from the heat dissipation shell plate 2, reducing heat accumulation and improving its heat dissipation effect. Both surfaces of the heat dissipation shell plate 2 can be used, allowing for installation according to the needs of the operator without the need for alignment, providing convenience. During installation, thermal grease should be applied to the contact surface between the heat dissipation shell plate 2 and the heating element to improve thermal conductivity.

[0021] In this embodiment, as a preferred option, the first sealing element includes a first sealing plate 6 and a plurality of first sealing plugs 7. The plurality of first sealing plugs 7 are spaced apart on the surface of the first sealing plate 6 and are inserted between two adjacent spacers 3 in the liquid storage cavity 1. The end face of the spacer 3 is spaced apart from the first sealing plate 6. A first flow channel is formed on the first sealing plug 7. By setting the first sealing plate 6, one end of the heat dissipation shell plate 2 can be sealed. With the setting of the first sealing plug 7, one end of two adjacent spacers can be blocked. With the opening of the first flow channel, a serpentine flow channel is formed. A sealing ring is provided on the outer surface of the first sealing plug 7. The use of the sealing ring is a common and well-known means, which is only cited here and will not be described in detail.

[0022] In this embodiment, as a preferred option, the second sealing element includes a second sealing plate 8 and a plurality of second sealing plugs 9. The plurality of second sealing plugs 9 are spaced apart on the surface of the second sealing plate 8 and are inserted between two adjacent spacers 3 in the liquid storage cavity 1. The end face of the spacer 3 is spaced apart from the second sealing plate 8. The second flow channel is formed on the second sealing plug 9. The second sealing plug 9 and the first sealing plug 7 are alternately arranged along the first direction. By setting the second sealing plate 8, one end of the heat dissipation shell plate 2 can be sealed. With the setting of the second sealing plug 9, one end of two adjacent spacers can be blocked. With the opening of the second flow channel, a serpentine flow channel is formed. The outer surface of the second sealing plug 9 is provided with a sealing ring. The use of the sealing ring is a common and well-known means, which is only cited here and will not be described in detail.

[0023] In this embodiment, as a preferred solution, both ends of the heat dissipation shell plate 2 are provided with mounting grooves 10. The groove surfaces of the mounting grooves 10 are symmetrically inclined. The first sealing plate 6 and the second sealing plate 8 are respectively placed in the two mounting grooves 10. The bottom of the two mounting grooves 10 is provided with mounting holes. The surfaces of the first sealing plate 6 and the second sealing plate 8 facing the mounting grooves 10 are provided with mounting blocks 11 that cooperate with the mounting holes. The inclined slope of the groove 10 facilitates the accurate installation of the first sealing plate 6 and the second sealing plate 8, further improving convenience. The installation holes and mounting blocks 11 enable quick positioning of the connection between the first sealing plate 6 and the heat sink housing and between the second sealing plate 8 and the heat sink housing.

[0024] In this embodiment, as a preferred option, the liquid inlet pipe 4 is disposed on the surface of the first sealing plate 6 or the second sealing plate 8 away from the heat dissipation shell plate 2, the liquid outlet pipe 5 is slidably connected to the heat dissipation shell plate 2, and a drainage channel 12 is opened on the inner side wall of the liquid storage cavity 1. The diameter of the opening of the drainage channel 12 toward the liquid storage cavity 1 is larger than the diameter of the opening of the drainage channel 12 toward the liquid outlet pipe 5. The liquid inlet pipe 4 is installed on the first sealing plate 6. Through the connection between the liquid inlet pipe 4 and the first sealing plate 6, after the first sealing plate 6 is installed with the heat sink housing, the liquid can enter the liquid storage chamber 1 through the liquid inlet pipe 4, and flow to the liquid outlet pipe 5 through the formed serpentine flow channel for discharge. Through the connection between the liquid outlet pipe 5 and the heat sink housing 2, the liquid outlet pipe 5 can slide inside the heat sink housing 2. The purpose is that when using either side of the heat sink housing, the liquid outlet pipe 5 can extend out of the matching heat sink housing side, so that the output end of the liquid outlet pipe 5 is always facing upward. The purpose of keeping it facing upward is to prioritize the discharge of air bubbles. By the diameter of the drain channel 12 decreasing from large to small, the flow rate of the cooling medium can be increased, further reducing air bubbles. At the same time, the cooling medium can fill the liquid storage chamber 1 first before flowing out, avoiding the cooling medium flowing out before filling the liquid storage chamber 1 and making sufficient contact with the inner wall of the heat sink housing, which would affect the heat dissipation effect.

[0025] In this embodiment, as a preferred option, the bottom of the mounting groove 10 communicates with the liquid storage chamber 1 through an opening in the receiving groove. An expansion sealing strip is provided in the receiving groove. The surfaces of the first sealing plate 6 and the second sealing plate 8 facing the liquid storage chamber 1 both abut against the expansion sealing strip. The side of the heat dissipation shell plate 2 is threadedly connected to a stop bolt 13 through an opening in the threaded hole. The surface of the mounting block 11 is slidably connected to the stop bolt 13 through an opening in the through hole, with one end of the stop bolt 13 protruding from the mounting block 11 abutting against the surface of the liquid outlet pipe 5. By setting the expansion sealing strip, the connection between the first sealing plate 6 and the heat dissipation shell plate 2 and the second sealing plate 8 and the heat dissipation shell plate 2 can be sealed. Expansion can prevent gaps, and the setting of the stop bolt 13 can limit the mounting block 11, thereby limiting the connection between the first sealing plate 6 and the heat dissipation shell plate 2 and the second sealing plate 8 and the heat dissipation shell plate 2. The sealing expansion sealing strip is a rubber expansion sealing strip, which is a known technology and is only cited here. The purpose is to expand and fill the gap to achieve sealing while generating extrusion force to push the first sealing plate 6 and the second sealing plate 8 to move away from the liquid storage chamber 1. In conjunction with the connection between the mounting block 11 and the stop bolt 13, it can play an auxiliary limiting role for the stop bolt 13, improve the tightness of the stop bolt 13, and effectively prevent the stop bolt 13 from accidentally loosening. One of the stop bolts 13 protrudes from the mounting block 11 and abuts against the surface of the liquid outlet pipe 5, while the other stop bolts 13 are threadedly connected to the heat sink shell plate 2 and protrude from the mounting block 11.

[0026] In this embodiment, as a preferred option, the liquid outlet pipe 5 includes a first channel 14 and a second channel 15. The output ends of the first channel 14 and the second channel 15 are respectively located at both ends of the liquid outlet pipe 5. When the liquid outlet pipe 5 slides back and forth in the heat dissipation housing to switch positions, the input ends of the first channel 14 and the second channel 15 are alternately connected to the drain channel 12. Through the arrangement of the first channel 14 and the second channel 15, the liquid outlet is kept facing upward. Through the connection between the first channel 14 and the second channel 15 and the drain channel 12, the cooling medium in the drain channel 12 can be discharged.

[0027] In this embodiment, as a preferred solution, the drain channel 12 is provided with a blocking component for blocking the drain channel 12. The first channel 14 and the second channel 15 are both provided with unblocking components. When the first channel 14 or the second channel 15 is connected to the drain channel 12, the unblocking component releases the blockage of the drain channel 12, so that the liquid in the drain channel 12 can enter the first channel 14 or the second channel 15. A sealing ring is provided between the liquid outlet pipe 5 and the heat dissipation shell. This is a known technology. By setting the blocking component, the drain channel 12 can be blocked, so that the cooling medium in the liquid storage chamber 1 cannot be discharged through the drain channel 12. By setting the unblocking component, when the first channel 14 or the second channel 15 is connected to the drain channel 12, the unblocking component releases the blockage of the drain channel 12, so that the liquid in the drain channel 12 can enter the first channel 14 or the second channel 15 and then be discharged. Both the first channel 14 and the second channel 15 are L-shaped pipes. The purpose is to ensure that when connected and used, the liquid outlet is always located at the top, or the liquid outlet is located at the bottom as needed. This can be adjusted according to the user's needs to further improve the applicability.

[0028] In this embodiment, as a preferred solution, the blocking component includes a blocking ball 16 and a blocking spring 17. A sealing plate is provided at the outlet of the drain channel 12, and the sealing plate is provided with a sealing hole. The blocking ball 16 abuts against the edge of the sealing hole, one end of the blocking spring 17 abuts against the blocking ball 16, and the other end of the blocking spring 17 is connected to the drain channel 12. The unblocking device includes an unblocking block 18 and an unblocking spring 19. The unblocking block 18 is frustoconical in shape, and one end of the unblocking spring 19 is fixedly installed on one end of the unblocking block 18. When the input end of the first channel 14 or the input end of the second channel 15 is connected to the drain 12, the elastic force of the unblocking spring 19 is greater than the elastic force of the blocking spring 17. Through the connection between the blocking spring 17 and the blocking ball 16, the blocking spring 17 can press against the blocking ball 16 to block the drain 12 and prevent the cooling medium from flowing out. When the first channel 14 or the second channel 15 is connected to the drain 12, the unblocking spring 19 applies a certain force to the unblocking block 18. When the unblocking block 18 is pushed into the drain channel 12, after the unblocking block 18 contacts the blocking ball 16, it overcomes the action of the blocking spring 17 on the blocking ball 16 and pushes the blocking ball 16 towards the liquid storage chamber 1 to make the drain channel 12 unobstructed. The drain channel 12 delivers the cooling medium to the first channel 14 or the second channel 15. When it is necessary to switch channels or reset, the unblocking block 18 is set in a frustum shape. When the unblocking block 18 moves with the liquid outlet pipe 5, the slope of the unblocking block 18 contacts the wall of the drain channel 12, squeezing the unblocking block 18 into the first channel 14 or the second channel 15. The slope of the unblocking block 18 has through holes, which flow out through the drain channel 12.

[0029] In this embodiment, as a preferred solution, the heat dissipation assembly includes fins 20 and a negative pressure fan 21. The fins 20 are detachably connected to the surface of the heat dissipation shell 2 via bolts. The negative pressure fan 21 is fixedly installed on the surface of the fins 20 away from the heat dissipation shell 2. Through the connection between the fins 20 and the heat dissipation shell 2, the installation position of the fins 20 can be switched so that both sides of the heat dissipation shell 2 can be connected and installed with the heat-generating element, thereby increasing the applicability of the heat dissipation shell 2 and reducing the trouble of selection.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
