Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, and in particular to a double-tower heat sink. Background Technology

[0002] A dual-tower heatsink is a common heat dissipation device used in electronic devices. Its main components include: a base, heat pipes fixed to the base, two fin assemblies mounted on the heat pipes, and a cooling fan installed between the two fin assemblies. During operation, the base connects to the electronic device, allowing the heat pipes to contact the high-power components. The heat generated by these components is transferred to the fin assemblies via the heat pipes, and the heat is dissipated into the air by the heat sinks on the fin assemblies. The cooling fan, located between the two fin assemblies, generates airflow to accelerate heat dissipation.

[0003] The drawbacks of traditional dual-tower radiators are:

[0004] Firstly, the cooling fan is attached to both sides of the fin assembly by two spring clips. The electronic device needs to reserve lateral space for operating the spring clips, which increases the difficulty of the already compact internal space layout.

[0005] Secondly, while airflow improves heat dissipation efficiency, it also brings in dust from the outside air, causing the dust to adhere to the surface of the heat sink and cooling fan. Since the heat sink is usually fixed to the heat pipe by welding, it is very difficult to clean. Utility Model Content

[0006] Based on this, the present invention provides a dual-tower heat sink, which uses a rib-like mechanism to attach heat sink fins to form a fin assembly, and uses a support plate and clamps to lock the fin assembly. Simultaneously, a pressure plate cooperates with the ribs and support plate, clamping the cooling fan between the support plate, pressure plate, and fin assembly. This not only changes the way the cooling fan is installed and removed, changing the unlocking operation from side to vertical, but also allows for easy disassembly of the fin assembly, improving the issue of lateral space occupation in electronic devices and facilitating the cleaning of the cooling fan and heat sink.

[0007] A dual-tower radiator, comprising:

[0008] Support module; the support module includes: a base, multiple heat pipes mounted on the base, multiple clamps sleeved on the heat pipes, and a support plate sleeved on each heat pipe; the insertion depth of the support plate into the heat pipe is limited by at least one clamp;

[0009] Two fin groups are connected to the support module; the two fin groups are symmetrically arranged and are both sleeved on the heat pipe from top to bottom; the top of each fin group is limited by at least one clamp; each fin group includes: a heat sink sleeved on the heat pipe and two ribs respectively clamped on the heat sink; the heat sink has a convex first lateral latch on both sides; the ribs are U-shaped; the ribs have a second lateral latch on both sides that are spaced apart along the length direction and are concave; the ribs and the heat sink are clamped together by the first lateral latch and the second lateral latch; the inner side of the open end of the rib is also provided with a third lateral latch;

[0010] A cooling fan located between the two fin assemblies; the bottom of the cooling fan abuts against the support plate; and

[0011] A pressure plate is connected between two fin assemblies; the pressure plate is X-shaped and abuts against the top of the cooling fan; each end of the pressure plate is correspondingly engaged with the third lateral slot of a rib.

[0012] In the aforementioned dual-tower heatsink assembly, the support module is assembled first. Next, multiple heatsink fins are snapped together using ribs to form fin groups. Then, the fin groups are fitted onto the heat pipes and secured with clamps and support plates. Finally, the cooling fan is placed between the two fin groups, and a pressure plate is placed on top of the fan, its end snapped to the ribs to fix the fan's position. When the fan needs to be removed or installed, the pressure plate can be manipulated to unlock the fan, eliminating the need for lateral space and simplifying the internal layout of electronic devices. When cleaning the heatsinks and fan, the fan is removed, the clamps securing the fin groups are unlocked, the entire fin group is pulled out of the heat pipes, and the ribs are removed to disassemble the fin group, facilitating thorough cleaning of each heatsink. The operation is simple and the cleaning process is easy. This design utilizes ribs to snap together the heatsinks to form fin groups, and support plates and clamps to lock the fin groups in place. Meanwhile, the pressure plate, in conjunction with the frame and support plate, clamps the cooling fan between the support plate, the pressure plate, and the fin assembly. This not only changes the way the cooling fan is installed and removed, changing the unlocking operation from side to vertical, but also allows for easy disassembly of the fin assembly, improving the issue of lateral space occupation in electronic devices and facilitating the cleaning of the cooling fan and heatsink.

[0013] In one embodiment, the base includes: a main body and a base plate detachably connected to the main body; the main body has a slot for engaging a heat pipe; the base plate is located at the opening of the slot and is used to lock the heat pipe onto the main body. When it is necessary to install the heat pipe on the base, the base plate can be removed from the main body first, then the heat pipe can be inserted into the slot of the main body, and then the base plate can be used to partially restrict the heat pipe in the slot, thereby fixing the heat pipe onto the base.

[0014] In one embodiment, the tray has wiring holes for the cooling fan's wiring harness to pass through. These wiring holes allow the user to extend the cooling fan's wiring harness downwards through the tray to connect electronic devices.

[0015] In one embodiment, the heat sink has limiting strips protruding towards the cooling fan on both sides, and the limiting strips are located outside the cooling fan. The limiting strips of the two fin groups together constitute a limiting structure that restricts the sides of the cooling fan, so that the two sides of the cooling fan are restricted between the two fin groups.

[0016] In one embodiment, the rib is a structure formed by bending a flexible stainless steel strip. When operating the rib, the user squeezes the two sides of the rib inward, causing the stainless steel strip to deform inward so that it can be easily inserted into the heat sink. The operation is simple and inexpensive.

[0017] In one embodiment, the bottom of the pressure plate has evenly distributed protrusions. Using protrusions to achieve contact between the pressure plate and the cooling fan allows for a better fit to the shape of the cooling fan's periphery.

[0018] In one embodiment, the clamp includes a collar that fits onto the heat pipe and an adjusting screw connecting the collar, the adjusting screw being used to adjust the tightness of the collar. In operation, the collar is first fitted onto the heat pipe, and then the adjusting screw is tightened; the operation is simple. Attached Figure Description

[0046] like Figures 1 to 15 As shown, it is a dual-tower radiator 100 according to one embodiment of the present invention.

[0047] like Figures 1 to 3 As shown, the dual-tower heatsink 100 includes: a support module 10, two fin groups 20 connected to the support module 10, a cooling fan 30 located between the two fin groups 20, and a pressure plate 40 connected between the two fin groups 20. The support module 10 is used to connect to electronic devices and to contact high-power devices to transfer heat to the fin groups 20. The fin groups 20 receive the transferred heat from the support module 10 and dissipate it into the air. The cooling fan 30 generates airflow to improve the heat dissipation efficiency of the fin groups 20. The pressure plate 40 secures the cooling fan 30 between the fin groups 20 and the support module 10.

[0048] The following text, combined with Figures 1 to 15 Further explanation is provided regarding the aforementioned dual-tower radiator 100.

[0049] like Figure 4 and Figure 5 As shown, the support module 10 includes: a base 11, a plurality of heat pipes 12 mounted on the base 11, a plurality of clamps 13 sleeved on the heat pipes 12, and a support plate 14 sleeved on each heat pipe 12. The insertion depth of the support plate 14 into the heat pipe 12 is limited by at least one clamp 13 (for example, in this embodiment, four clamps 13 are distributed at the bottom of the support plate 14). Figure 5As shown, in this embodiment, the heat pipes 12 are all copper capillary tubes, and each heat pipe 12 is U-shaped and passes through the base 11.

[0050] like Figure 5 As shown, in this embodiment, the base 11 includes a main body 111 and a base plate 112 detachably connected to the main body 111 (for example, in this embodiment, the main body 111 and the base plate 112 are connected together by screws). The main body 111 is provided with a slot for engaging the heat pipe 12. The base plate 112 is located at the opening of the slot and is used to lock the heat pipe 12 onto the main body 111. When it is necessary to install the heat pipe 12 onto the base 11, the base plate 112 can be removed from the main body 111 first, and then the heat pipe 12 can be engaged into the slot of the main body 111. Then, the base plate 112 partially restricts the heat pipe 12 in the slot, thereby fixing the heat pipe 12 onto the base 11.

[0051] In this design, the clamp 13 can take various forms. For example, in this embodiment, the clamp 13 includes a collar fitted onto the heat pipe 12 and an adjusting screw connecting the collar. The adjusting screw is used to adjust the tightness of the collar. During operation, simply fit the collar onto the heat pipe 12 and then tighten the adjusting screw; the operation is simple.

[0052] Considering that the cooling fan 30 is typically connected to electronic equipment via a wiring harness to obtain power and control signals, therefore, for ease of wiring, combined with... Figure 4 and Figure 6 As shown, in this embodiment, the tray 14 has a wiring hole 141 through which the wiring harness of the cooling fan 30 passes. The wiring hole 141 facilitates the user to pass the wiring harness of the cooling fan 30 through the tray 14 and extend it downwards to connect electronic devices.

[0053] Furthermore, to facilitate the connection between the base 11 and the electronic device, in some embodiments, the support module 10 may further include a mounting plate for connecting the base 11, and the mounting plate has spring screws at both ends. When the base 11 is connected to the electronic device, it is connected to the electronic device through the spring screws on the mounting plate, and the mounting plate presses the base 11 onto the electronic device.

[0054] Combination Figure 2 and Figure 3 As shown, two fin groups 20 are symmetrically arranged and are both sleeved on the heat pipe 12 from top to bottom. The top end of each fin group 20 is limited by at least one clamp 13 (for example, in this embodiment, each fin group 20 has two clamps 13 at its top end).

[0055] like Figure 7 and Figure 8 As shown, each fin assembly 20 includes: a heat sink 21 sleeved on the heat pipe 12 and two ribs 22 respectively snapped onto the heat sink 21. Figure 9 As shown, the heat sink 21 has convex first lateral latches 211 on both sides. Figure 10 and Figure 11 As shown, the rib 22 is U-shaped. Both sides of the rib 22 are provided with recessed second lateral slots 221 spaced apart along its length. The height of the second lateral slots 221 matches the thickness of the heat sink 21, and the distance between two adjacent second lateral slots 221 along the length of the rib 22 is equal to the distance between two adjacent heat sinks 21. That is, the rib 22 can provide lateral and longitudinal positioning for the array of heat sinks 21. The rib 22 and the heat sink 21 are engaged together via first lateral slots 211 and second lateral slots 221. A third lateral slot 222 is also provided on the inner side of the open end of the rib 22, which is used to mate with the pressure plate 40.

[0056] Preferably, in this embodiment, the rib 22 is a structure formed by bending an elastic stainless steel strip. When operating the rib 22, the user squeezes the two sides of the rib 22 inward, causing the stainless steel strip to deform inward so that it can be inserted into the heat sink 21. The operation is simple and the cost is low.

[0057] Combination Figure 9 and Figure 14 As shown, the heat sink 21 has limiting strips 212 protruding towards the cooling fan 30 on both sides, and the limiting strips 212 are located on the outside of the cooling fan 30. The limiting strips 212 of the two fin groups 20 together constitute a limiting structure that restricts the sides of the cooling fan 30, so that the two sides of the cooling fan 30 are restricted between the two fin groups 20.

[0058] like Figure 2 As shown, the bottom of the cooling fan 30 abuts against the support plate 14. The front end (front) of the cooling fan 30 faces one of the fin groups 20, while the rear end (back) of the cooling fan 30 faces the other fin group 20.

[0059] Combination Figure 1 and Figure 12 As shown, the pressure plate 40 is X-shaped and abuts against the top of the cooling fan 30. Each end of the pressure plate 40 is correspondingly engaged with a third lateral latch 222 of a rib 22 (for example, in this embodiment, each of the four ends of the pressure plate 40 has an outwardly protruding lug 41). Considering that the top and bottom ends of the cooling fan 30 are usually not flat, to ensure stable contact between the pressure plate 40 and the cooling fan 30, as shown... Figure 13 As shown, in this embodiment, the bottom of the pressure plate 40 is provided with evenly distributed protrusions 42. The protrusions 42 are used to achieve the contact between the pressure plate 40 and the cooling fan 30, which can better adapt to the shape of the periphery of the cooling fan 30.

[0060] Brief description of working principle:

[0061] like Figure 4 As shown, during assembly, the support module 10 is assembled first. Then, as... Figure 7 As shown, multiple heat sinks 21 are snapped together by the ribs 22 to form a fin assembly 20. Then, as... Figure 14 As shown, after the fin assembly 20 is fitted onto the heat pipe 12, it is secured using clamps 13 and a support plate 14. Finally, combined with... Figure 14 and Figure 15 As shown, the cooling fan 30 is placed between the two fin assemblies 20, and then the pressure plate 40 is placed on top of the cooling fan 30, with the end of the pressure plate 40 snapped together with each of the support strips 22 to fix the cooling fan 30 in its position. When it is necessary to disassemble or assemble the fan, the installation of the cooling fan 30 can be unlocked by operating the pressure plate 40. This operation does not require occupying lateral space, reducing the complexity of the internal space layout of electronic devices. When it is necessary to clean the heat sink 21 and the cooling fan 30, after removing the fan, the clamps 13 locking the fin assembly 20 are unlocked, and the entire fin assembly 20 is pulled out from the heat pipe 12. Then, the support strips 22 are removed, and the fin assembly 20 can be disassembled, making it easy to thoroughly clean each heat sink 21. The operation is simple and the cleaning difficulty is low.

[0062] The aforementioned dual-tower heatsink 100 uses a frame 22 to snap onto the heat sink 21, forming a fin assembly 20, which is then locked in place by a support plate 14 and clamps 13. Simultaneously, a pressure plate 40 engages with the frame 22 and support plate 14, clamping the cooling fan 30 between the support plate 14, pressure plate 40, and fin assembly 20. This not only changes the way the cooling fan 30 is installed and removed—changing the unlocking operation from side to vertical—but also allows for easy disassembly of the fin assembly 20, improving the issue of lateral space occupation in electronic devices and facilitating cleaning of the cooling fan 30 and heat sink 21.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
