Description

Technical Field

[0001] The utility model relates to the field of physics, in particular to a heat dissipation device, in particular to a high-efficiency and lightweight radiator. Background Art

[0002] In the existing technology, there are two types of heat sinks: one-piece extruded heat sinks and insert heat sinks. One-piece extruded heat sinks are formed in one piece by a mold. The advantages are low cost and easy processing. The disadvantage is that the extrusion process limits the size of the heat sink. It is impossible to achieve the extrusion multiple that is too high. The multiple = (total height - substrate thickness) / (rib spacing - rib thickness). Currently, one-piece extruded products are commonly less than 20 times. Insert heat sinks are realized by using a substrate + rib plate method. All rib plates are fixed by riveting. The process is complex and the cost is high. Utility Model Content

[0003] The purpose of the present invention is to provide a high-efficiency lightweight radiator, which aims to solve the technical problems in the prior art that the one-piece extruded radiator limits the size of the radiator and cannot achieve a higher multiple, and the insert radiator has a complex process.

[0004] The utility model provides a high-efficiency lightweight radiator, including a substrate, on which a plurality of first ribs are arranged at intervals, the first ribs and the substrate being integrally formed, a hollow groove being formed between any two adjacent first ribs, a second rib being arranged in each of some or all of the hollow grooves, the second ribs being parallel to the first ribs, and the bottoms of the second ribs being fixedly connected to the substrate.

[0005] Furthermore, the first ribs are evenly distributed on the substrate.

[0006] Furthermore, the bottom of the second rib is fixed to the base plate by riveting.

[0007] Compared with the existing technology, the effect of the present invention is positive and obvious. The present invention adopts an integrated extrusion + insert structure. The base plate and the first rib are integrally formed through an extrusion process. Then, the rib is seeded at the heat source with relatively large heat flux density on the product, and the second rib is riveted. This can meet higher multiple requirements and improve the heat dissipation capacity of the local area of ​​the radiator. Under the same conditions, the performance of the radiator can be improved by 15%. It has a wide range of adaptability and can adopt the method of local seeding to strengthen the heat dissipation capacity of the radiator in areas with high heat source density on the substrate. The product is lightweight and energy-saving, and can specifically improve the heat dissipation efficiency of the radiator. Different from conventional seeded radiators, it effectively avoids the loss of heat dissipation capacity due to excessive seeding, reduces the use of ribs, and reduces material waste.
