A ring-shaped heat sink

Abstract

This utility model belongs to the field of heat sink technology, and in particular to a ring-shaped heat sink, comprising a ring plate. A set of mounting blocks are arranged in a ring array on the outer surface of the ring plate. Each of the mounting blocks has a slot at its upper end, and a locking block is slidably connected in the slot. A heat sink body is mounted on one end of each locking block. The mounting block is provided with a mounting assembly. The heat sink body has heat dissipation holes. The mounting assembly includes limiting plates mounted at both ends of the mounting block. A stop plate is slidably connected between the two limiting plates. A fixing seat is mounted on the upper end of the mounting block. A guide rod is mounted in the fixing seat, and two sliders are slidably connected to the guide rod. This utility model, through the setting of the mounting assembly, allows for quick disassembly of the heat sink body, thereby ensuring the heat dissipation effect of subsequent components, avoiding the need to replace the entire heat sink body due to damage to a single heat sink body, which would increase costs, and improving flexibility and convenience.

Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, specifically a ring-shaped heat sink. Background Technology

[0002] A heat sink is a device for dissipating heat from electronic components in electrical appliances that are prone to overheating. They are usually made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets.

[0003] According to patent authorization number CN 220858718 U, a ring-shaped aluminum alloy heat sink structure is disclosed. In this application, multiple heat sink fins are installed on the heat sink body, which is not convenient to disassemble and replace individually, resulting in a large cost for overall replacement and inconvenience in use.

Each set of mounting blocks has a slot at its upper end. A card block is slidably connected in the slot. A heat sink body is mounted on one end of the card block. The mounting block is provided with a mounting component. The heat sink body has heat dissipation holes.

[0009] Furthermore, the mounting assembly includes limiting plates installed at both ends of the mounting block, with a stop plate slidably connected between the two limiting plates. A fixed seat is installed at the upper end of the mounting block, and a guide rod is installed inside the fixed seat. Two sliders are slidably connected to the guide rod, and a rotating plate is rotatably connected to one end of each of the two sliders. Both rotating plates are rotatably connected to the stop plate. A bidirectional screw is rotatably connected inside the fixed seat, and a handwheel is installed at one end of the bidirectional screw. The bidirectional screw is threadedly connected to the slider.

[0010] Furthermore, the abutment has a U-shaped structure and abuts against the locking block.

[0011] Furthermore, the cross-section of the card block is T-shaped.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides a ring-shaped heat sink, which has the following beneficial effects:

[0014] This invention allows for the quick disassembly of the heat sink body through the installation components, thereby ensuring the heat dissipation effect of subsequent components and avoiding the need to replace the entire heat sink body due to damage, which would increase costs. This improves flexibility and convenience. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a ring-shaped heat sink, including a ring plate 1. A set of mounting blocks 2 are mounted in a ring array on the outer surface of the ring plate 1. Each set of mounting blocks 2 has a slot 3 at its upper end. A locking block 4 is slidably connected in the slot 3. A heat sink body 5 is mounted on one end of the locking block 4. The mounting block 2 is provided with a mounting component 7. The heat sink body 5 has heat dissipation holes 6. By setting the mounting component 7, the heat sink body 5 can be quickly disassembled, thereby ensuring the heat dissipation effect of subsequent components and avoiding the phenomenon that the entire heat sink body 5 needs to be replaced due to damage to a single heat sink body 5, which would increase costs and improve flexibility and convenience.

[0022] like Figure 3As shown, in some embodiments, the mounting assembly 7 includes limiting plates 75 installed at both ends of the mounting block 2. A stop plate 76 is slidably connected between the two limiting plates 75. A fixing seat 71 is installed at the upper end of the mounting block 2. A guide rod 72 is installed inside the fixing seat 71. Two sliders 73 are slidably connected to the guide rod 72. A rotating plate 74 is rotatably connected to one end of each slider 73. Both rotating plates 74 are rotatably connected to the stop plate 76. A bidirectional screw 77 is rotatably connected inside the fixing seat 71. A handwheel 78 is installed at one end of the bidirectional screw 77. The bidirectional screw 77 is threadedly connected to the slider 73. When replacing, by rotating the handwheel 78, the bidirectional screw 77 is rotated, which causes the slider 73 to slide on the guide rod 72, which causes the rotating plate 74 to rotate, and causes the stop plate 76 to slide on the two limiting plates 75, so that the stop plate 76 no longer abuts against the locking block 4. Then the locking block 4 can slide up and slide out of the slot 3, completing the disassembly and replacement of the heat sink body 5.

[0023] like Figure 2 As shown, in some embodiments, the abutment 76 has a U-shaped structure and abuts against the card block 4; this facilitates the disassembly and replacement of the heat sink body 5.

[0024] like Figure 2 As shown, in some embodiments, the cross-section of the card block 4 is T-shaped; the structure is simple.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
