Description

Stacked close-fitting fin structure radiator

Technical Field

The utility model relates to the technical field of radiators, in particular to a stacked close-fitting fin structure radiator.

Background

The thermal management scheme is accompanied by the increasing of thermal power consumption, and various high-performance solutions such as an air cooling heat dissipation scheme, a liquid cooling heat dissipation scheme, an immersed liquid cooling heat dissipation scheme and the like are endlessly layered, but the performance and the stability durability and the safety of the heat radiator are often not simultaneously compatible, and the air cooling module scheme often has high price due to the need of increasing the heat pipe cost and the nickel electroplating cost. The liquid cooling scheme has the defect that cooling liquid corrodes the radiator for years and months, and the risk of liquid leakage is accompanied, so that periodic maintenance, overhaul and the like are not needed.

Based on this, the traditional passive heat dissipation scheme is inferior to the air cooling module scheme and the liquid cooling scheme in heat dissipation performance, but has excellent stability and price advantages, and still has a wide application space, so how to develop the performance to the greatest extent under the bottleneck of passive heat dissipation is a primary task.

The heat dissipation device of the passive heat dissipation scheme comprises an extrusion type heat radiator, a relieved tooth type heat radiator and a gear shaping type heat radiator. The extruded radiator has the advantages of low cost and the like, and the subsequent process cost of the profile radiator is low after the design of the front-stage die is finished, however, the width of the radiator cannot exceed 300mm (limitation) due to the limitation of the extrusion process and the extruder table, and the larger the width size of the radiator is, the larger tonnage extrusion equipment is required, and the brought cost is multiplied. Therefore, how to extrude the radiator with wider size on the small-tonnage extrusion equipment, and simultaneously, make the radiator possess inherent stability and safety, and compromise economy and heat-relieving performance of the radiator, are important subjects on the research and development roads. For this purpose, we propose a stacked close-fitting fin structure heat sink.
