Abstract
Description
Technical Field
[0001] This invention relates to the field of radiator technology, and in particular to a finned radiator. Background Technology
[0002] In today's society, electronic products are becoming increasingly indispensable components. In the current highly competitive market for electronic products, the products that the public demands are becoming more and more sophisticated. With the rapid development of the social economy, heat sinks have become an essential component of various integrated circuits. Existing through-type heat sinks are prone to problems such as tooth misalignment and substrate protrusion during product output due to their thinness, small tolerances, and the need to control weight per meter. This leads to product quality issues, greatly increases production costs, and fails to meet industry demands.
[0003] To address this, there are low-cost plug-in finned heat sinks with patent number CN219248406U and easily manufactured plug-in finned heat sinks with patent number CN219248402U. While these heat sinks solve the aforementioned problems, they also have the following drawbacks: although the thickened heat sink plate protects the heat sink fins, the insufficient strength of the heat sink fins themselves can still affect their stability and safety. At the same time, these heat sinks cannot effectively guarantee the strength of the heat sink plate to prevent it from bending, which may cause the heat sink plate to bend and affect the heat sink fins. Summary of the Invention
[0004] The purpose of this invention is to provide a finned heat sink.
[0005] The technical problem of this invention is mainly solved by the following technical solution:
[0006] A finned radiator includes a radiator body integrally formed from a heat dissipation base plate, heat dissipation fins, and heat dissipation plates. The bottom of the heat dissipation base plate is provided with reinforcing ribs, and both ends of the top of the heat dissipation base plate are provided with heat dissipation plates. An anti-bending rib is provided at one side of the included angle between the heat dissipation plate and the heat dissipation base plate, and several diagonal tie ribs are provided at the other side of the included angle between the heat dissipation plate and the heat dissipation base plate. Several heat dissipation fins are also evenly provided on the top of the heat dissipation base plate between the two sets of heat dissipation plates. The heat dissipation fins have a wavy structure, wherein the height of the heat dissipation fins on both sides is greater than the height of the heat dissipation fins in the middle, and a V-shaped notch is formed between the tops of the multiple sets of heat dissipation fins.
[0007] Preferably, the height of the heat sink is not higher than the height of the heat sink plate.
[0008] Preferably, the thickness of the heat sink is greater than the thickness of the heat fin.
[0009] Preferably, the anti-bending rib has a 90-degree sector-shaped cross-section, and the anti-bending rib is disposed between the two sets of heat dissipation plates. The two right-angled sides of the anti-bending rib are respectively fixedly connected to the corresponding heat dissipation base plate and the side wall of the heat dissipation plate.
[0010] Preferably, the diagonal bracing strip is disposed on the heat dissipation substrate outside the heat dissipation plate, and the sidewall of the diagonal bracing strip is fixedly connected to the heat dissipation substrate and the heat dissipation plate respectively.
[0011] The beneficial effects of this invention are as follows: This invention provides multi-layered reinforcement and fixation at the connection between the heat sink and the heat sink substrate through anti-bending ribs and diagonal tie ribs, preventing the heat sink from bending at the connection between the heat sink and the heat sink substrate and coming into contact with the heat sink fins, thereby improving the safety of the heat sink fins. At the same time, due to the wavy structure characteristics of the heat sink fins, even if the heat sink fins are relatively thin, their overall strength and safety can be effectively improved, and their heat dissipation area can also be indirectly increased to improve heat dissipation efficiency and effect. Furthermore, the height of the top of several heat sink fins gradually decreases from both sides to the middle, making it difficult for external objects to come into contact with the top surface of the heat sink fins when they come into contact with the top of the heat sink, thus effectively ensuring the safety and overall strength of the thinner heat sink fins.

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0016] A finned radiator includes a radiator body integrally formed from a heat dissipation base plate 1, heat dissipation fins 2, and heat dissipation plates 3. The bottom of the heat dissipation base plate 1 is provided with reinforcing ribs 4, and heat dissipation plates 3 are provided at both ends of the top of the heat dissipation base plate 1. An anti-bending rib 5 is provided at one of the included angles between the heat dissipation plates 3 and the heat dissipation base plate 1. The anti-bending rib 5 has a 90-degree fan-shaped cross-section and is disposed between two sets of heat dissipation plates 3. The two right-angled sides of the anti-bending rib 5 are fixedly connected to the side walls of the corresponding heat dissipation base plate 1 and heat dissipation plates 3, respectively.
[0017] Several diagonal bracing strips 6 are provided at the other side of the included angle between the heat dissipation plate 3 and the heat dissipation substrate 1. The diagonal bracing strips 6 are provided on the heat dissipation substrate 1 outside the heat dissipation plate 3, and the sidewalls of the diagonal bracing strips 6 are fixedly connected to the heat dissipation substrate 1 and the heat dissipation plate 3 respectively.
[0018] The top of the heat dissipation substrate 1 is also uniformly provided with a number of heat dissipation fins 2 located between the two sets of heat dissipation plates 3. The height of the heat dissipation fins 2 is not higher than the height of the heat dissipation plate 3. The thickness of the heat dissipation plate 3 is greater than the thickness of the heat dissipation fins 2. The heat dissipation fins 2 have a wavy structure, wherein the height of the heat dissipation fins 2 on both sides is greater than the height of the heat dissipation fins 2 in the middle, and a V-shaped notch 7 is formed between the tops of the multiple sets of heat dissipation fins 2.
[0019] This invention uses anti-bending ribs 5 and diagonal bracing ribs 6 to provide multi-layered reinforcement and fixation at the connection between the heat sink 3 and the heat sink substrate 1, preventing the heat sink 3 from bending at the connection between it and the heat sink substrate 1 and coming into contact with the heat sink 2, thereby improving the safety of the heat sink 2. At the same time, due to the wavy structure of the heat sink 2, even if the heat sink 2 is relatively thin, its overall strength and safety can be effectively improved, and its heat dissipation area can also be indirectly increased to improve heat dissipation efficiency and effect. Furthermore, the height of the top of several heat sinks 2 gradually decreases from both sides to the middle, making it difficult for external objects to come into contact with the top surface of the heat sink 2 when they come into contact with the top of the heat sink 3, thus effectively ensuring the safety and overall strength of the relatively thin heat sink 2.
[0020] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
