Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a CFP2 radiator. Background Technology

[0002] CFP2 (C Form-factor Pluggable 2) is the second-generation packaging form of the CFP standard, designed specifically for 100G / 400G high-speed transmission. It is primarily used in high-speed interconnection scenarios such as data centers, telecom core networks, and 5G transport networks. CFP2 modules have relatively high power consumption, with some models exceeding 20W, therefore requiring a heat sink for cooling.

[0003] Figure 1 It is the existing CPF2 cage without a radiator. Figure 2 These are CPF2 cages for installing traditional radiators, all taken from the Amphenol CFP2 manual. Figure 1 , 2 As shown, the CFP2 heatsink 2 is generally used in conjunction with the CFP2 cage. The CFP2 cage usually has an opening on the top, through which the heatsink 2 contacts the CFP2 module and conducts heat.

[0004] The existing high-power CFP2 module heatsink is mounted directly above the CFP2 cage, with the heatsink teeth facing upwards. Its height exceeds the top surface of the CFP2 cage by more than 20mm. Adding the 13.8mm height of the CFP2 cage, the total height of the CFP2 assembly is approximately 34mm. The boards using this assembly generally need to be taller than 40mm, which limits the number of boards that can be installed in multi-board vertical rack devices. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a CFP2 heat sink, including a top plate, heat dissipation teeth on the rear and sides of the top plate, a boss in the middle of the heat dissipation teeth on both sides, and a boss ramp at the leading edge of the boss.

[0006] Several openings are provided on the top plate corresponding to the heat dissipation teeth on both sides. The openings are for the gasket to pass through. There is a limiting tooth below the gasket. There is an opening in the middle of the limiting tooth. The bottom of the opening is a platform. The two ends of the gasket are located on the platform. There is a round hole in the center of the gasket. The screw passes through the round hole and is threaded to the circuit board fixed on both sides of the CFP2 cage. There is a spring between the gasket and the tail of the screw.

[0007] Preferably, there are four openings, which are arranged in pairs on the top plate where the heat dissipation teeth are located on both sides.

[0008] Preferably, both the opening and the gasket are rectangular.

[0009] Preferably, the bottom of the screw has a stepped surface, the diameter of the lower part of the stepped surface is smaller than the diameter of the upper part of the stepped surface, and the stepped surface is used to abut against the surface of the circuit board.

[0010] Preferably, a groove is provided between the top plates where the heat dissipation teeth are located on both sides, and the boss is located on the bottom surface of the groove.

[0011] Preferably, the height of the heat dissipation denticles is 11.8 mm.

[0012] Preferably, the top plate has a length of 134.4 mm and a width of 75 mm.

[0013] This invention places the radiator teeth on the outer area of ​​the CFP2 cage and faces downwards. The radiator is 3.5mm higher than the CFP2 cage and about 10mm lower than the height of traditional radiators, thus enabling a wider range of applications. Attached Figure Description

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0030] like Figure 3-13 As shown, this utility model discloses a CFP2 heat sink, including a top plate 14. The rear and sides of the top plate 14 are provided with heat dissipation teeth, and a boss 3 is provided between the heat dissipation teeth on both sides. The boss 3 is used to embed into the CFP2 cage and fully contact the CFP2 module to conduct heat. A boss ramp 4 is provided at the front edge of the boss 3. When the CFP2 module is inserted, the boss ramp 4 plays a guiding role.

[0031] The heat sink can be made of toothed aluminum profile, with a boss 3 milled into it to fit into the CFP2 cage, ensuring full contact with the CFP2 module and conducting heat. A ramp 4 at the leading edge of the boss 3 serves as a guide when the CFP2 module is inserted.

[0032] Four rectangular openings 5 ​​are made on the heat sink. Rectangular shims 9 are installed in the openings 5. The shims 9 are clipped onto the limiting teeth 12 of the heat sink, and the shims 9 are located above the limiting teeth 12. The limiting teeth 12 can be machined from heat sink teeth. The limiting teeth 12 have a notch 10 in the middle. The bottom of the notch 10 is a platform. The shims 9 are moved down and both ends are located on the platform. A round hole 6 is made in the center of the shims 9. Four spring screws are used to fix the heat sink to the circuit board 13. The circuit board 13 has a threaded hole 11. The screw 8 passes through the round hole 6 of the shims 9. The spring 7 cannot pass through the hole. The spring 7 deforms and is squeezed between the shims 9 and the tail of the screw 8.

[0033] Circuit board 13 is fixedly connected to the CPF2 cage on both sides.

[0034] When the CPF2 module is inserted into the CFP2 cage, the module first contacts the radiator's boss ramp 4, causing the radiator to lift up. At the same time, the gasket 9 is lifted up, and the spring 7 is compressed, increasing the deformation of the spring 7. After the CPF2 module is fully inserted into the CFP2 cage, the deformation of the spring 7 applies a downward force, ensuring full contact between the CFP2 radiator and the CFP2 module, and fixing the radiator in place.

[0035] The bottom of the screw 8 is provided with a stepped surface 15, the diameter of the lower part of the stepped surface 15 is smaller than the diameter of the upper part of the stepped surface 15, and the stepped surface 15 is used to abut against the surface of the circuit board 13.

[0036] A groove 16 is provided on the top plate 14 between the heat dissipation teeth on both sides, and the boss 3 is located in the groove 16.

[0037] The height of the heat dissipation fins is 11.8 mm; the length of the top plate 14 is 134.4 mm and the width is 75 mm.

[0038] The manufacturing method of this CFP2 heat sink is as follows:

[0039] 1. Select 134.4*15.5mm toothed aluminum profile and cut it to a width of 75mm;

[0040] 2. Mill off part of the teeth according to the drawing;
