Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to an aluminum heat sink which is convenient for modular disassembly and assembly. Background Art

[0002] Heat sink is a device for dissipating heat from heat-prone electronic components in electrical appliances. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multiple sheets, etc. For example, the CPU in a computer uses a fairly large heat sink, as do the power tubes, line tubes in a TV, and the power amplifier tubes in an amplifier. As for the heat sink material, each material has different thermal conductivity. They are arranged from high to low in terms of thermal conductivity, namely silver, copper, aluminum, and steel. Relatively speaking, aluminum has a lower production cost, so it is widely used.

[0003] Most of the existing aluminum heat sinks are connected by screw locking or screw nuts. During daily use, the surface of the heat sink will be contaminated with a lot of floating dust in the air, which affects the heat sink effect. The gaps between the heat sinks are small and cannot be cleaned thoroughly. If cleaning is required, tools must be used to disassemble them, which is very inconvenient. In addition, the heat sink fins are easily broken during the disassembly process, causing the heat sink to be damaged as a whole and unusable, and the use is greatly limited. Utility Model Content

[0010] As an improvement, a plurality of rectangular grooves in left and right directions are evenly arranged on the top of the heat sink 1 along the front-to-back direction, and a filter net is arranged on the top of the heat sink 1.

[0011] As an improvement, a frustoconical rod is provided at each corner of an upper end of the heat sink, and the frustoconical rod is tightly sleeved with a pressure ring of a frustoconical structure that cooperates with the filter screen.

[0012] As an improvement, the height of the pressure ring is smaller than the height of the truncated cone rod, the pressure ring is made of rubber material, and the diameter of the inner wall of the upper end is smaller than the diameter of the truncated cone rod.

[0013] As an improvement, the shape of the through slot is irregular, the cross section of the limiting plate is the same irregular structure as the through slot, and the length of the limiting plate is greater than the distance between the two connecting plates.

[0014] As an improvement, rubber blocks are provided at both ends of the limit plate, and the rubber blocks are interference fit with the through slots.

[0031] An aluminum heat sink that is easy to modularize and disassemble, comprising a single aluminum heat sink 1 and a plurality of aluminum heat sinks 2 installed in the heat sink 1, the heat sink 1 being a shell structure with an opening facing downward, a plurality of vertical grooves 3 being evenly arranged on the front and rear inner walls of the heat sink 1 along the left and right directions, the lower ends of the grooves 3 extending out of the heat sink 1, and a single heat sink 2 2 being inserted between two opposite grooves 3; a notch 4 being arranged in the middle of the lower end of the heat sink 2, a connecting plate 5 being arranged on the left and right side walls of the heat sink 1, a through groove 6 being arranged on the side walls adjacent to each other below the two connecting plates 5, and a limiting plate 7 cooperating with the notch 4 being inserted between the two through grooves 6.

[0032] Through the above structure, the heat sink 2 can be inserted into the heat sink 1 and limited by the limiting plate 7. The assembly of the heat sink 1 and the heat sink 2 does not require the use of screws or screw nuts for locking, which is convenient for disassembly and assembly.

[0033] Embodiment 2

[0034] Based on Example 1, please refer to the attached Figure 5 , Attachment Figure 6 and attached Figure 7

[0035] A plurality of rectangular grooves 8 in left and right directions are evenly arranged above the heat sink 1 in the front-to-back direction, and a filter screen 9 is arranged above the heat sink 1; a truncated cone rod 10 is respectively arranged at the corners of the upper end of the heat sink 1, and the truncated cone rod 10 is tightly sleeved with a truncated cone structure pressure ring 11 that cooperates with the filter screen 9; the height of the pressure ring 11 is smaller than the height of the truncated cone rod 10, the pressure ring 11 is made of rubber, and the diameter of the inner wall of the upper end is smaller than the diameter of the truncated cone rod 10.

[0036] Through the above structure, the rectangular groove 8 can dissipate heat better, and the detachable filter 9 plays a protective role, which can reduce the dust from entering the heat sink 1 and the heat sink 2.

[0037] The shape of the through groove 6 is irregular, and the cross-section of the limiting plate 7 is the same irregular structure as the through groove 6. The length of the limiting plate 7 is greater than the distance between the two connecting plates 5. Rubber blocks 12 are provided at both ends of the limiting plate 7, and the rubber blocks 12 are interference fit with the through groove 6. The thickness of the limiting plate 7 in the upper and lower directions is less than the height of the recess 4.

[0038] Through the above structure, the limiting plate 7 can be inserted between the through grooves 6 without rotating, and can be pulled out by manpower, and the limiting plate 7 is located in the recess 4, so that the bottom of the device is flat.

[0039] The specific method of use is as follows: insert the heat sink 2 into the heat sink 1 in sequence, and then insert the limiting plate 7 into the recess 4 below the heat sink 2, so that the two ends of the limiting plate 7 pass through the through slot 6 of the connecting plate 5, to realize the modular assembly of the heat sink 1 and the heat sink 2. When cleaning is needed, only the limiting plate 7 needs to be pulled out from one end, and the heat sink 2 can be taken out in sequence, which is convenient for disassembly and cleaning. At the same time, the rectangular groove 8 on the heat sink can better dissipate heat, and the detachable filter screen 9 plays a protective role, which can reduce dust from entering the heat sink 1 and the heat sink 2.
