Description

Technical Field

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

[0002] In the field of radiator manufacturing, copper and copper alloys are widely used due to their excellent thermal conductivity, but their high cost and weight limit their application to some extent. In contrast, aluminum has significant advantages in terms of light weight and low cost, making it an ideal alternative to copper. Pure aluminum has better thermal conductivity than aluminum alloys, but its lower hardness makes it prone to deformation under mechanical loads, affecting heat dissipation efficiency and structural durability. Furthermore, radiators must withstand the thermal stress impact of drastic temperature cycles during long-term operation. Repeated thermal expansion and contraction can easily cause material fatigue, leading to fin deformation, cracking, or even breakage. Especially under complex operating conditions, the vibration caused by the high-speed rotation of the fan rotor can cause fin resonance, further exacerbating stress concentration at the root, accelerating fatigue damage, and ultimately leading to structural failure. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a high-strength radiator structure that solves the problem of easy resonance and breakage in existing radiators, thereby improving structural strength and service life.

[0004] The specific technical solution is as follows:

[0005] A high-strength heat sink structure includes a base, a base plate horizontally disposed at the lower end of the base, a plurality of horizontally arranged first fins longitudinally disposed at the upper end of the base, and a plurality of vertically arranged second fins horizontally disposed at the lower ends of both sides of the base. The ends of the second fins on the left and right sides of the base are flush with the sidewalls of the two outermost first fins, respectively. At least one positioning band is provided on the outer side of each of the first and second fins. The positioning band includes a first reinforcing strip disposed on the outer side of the first fins and two second reinforcing strips disposed on the ends of the second fins. A plurality of slots are horizontally arranged at the bottom middle of the first reinforcing strip, each slot engaging with the end of a first fin. The two ends of the first reinforcing strip are bent downwards, and the two ends of the bent first reinforcing strip are longitudinally connected to a second reinforcing strip by fasteners. A plurality of slots are also provided on one side of the second reinforcing strip, and the slots on the second reinforcing strip engage with the ends of the second fins. The bottom of the second reinforcing strip is fixed to the base plate by fasteners.

[0006] Furthermore, at least one reinforcing fin is provided among the plurality of first fins, the end of the reinforcing fin is provided with a groove, the bottom of the first reinforcing strip is provided with a protrusion at the position of the reinforcing fin, and the bottom of the protrusion is also provided with the slot, so that the protrusion is engaged with the groove through the slot to achieve horizontal positioning.

[0007] Furthermore, both ends of the first and second reinforcing strips are horizontally bent and equipped with support plates. The first reinforcing strip and the two adjacent ends of the second reinforcing strips are respectively connected by the support plates and fasteners. The second reinforcing strip and the lower end are supported on the substrate by the support plates and are also connected by fasteners.

[0008] Furthermore, the fastener includes a long screw and a nut. The long screw passes through the support plate at the bottom of the first reinforcing strip, the support plates at both ends of the second reinforcing strip, and the base plate from top to bottom. The upper end of the long screw is fixed to the support plate between the first and second reinforcing strips by the cooperation of the nut and the screw. The lower end of the long screw is fixed to the support plate at the lower end of the second reinforcing strip and the base plate by two nuts.

[0009] Furthermore, the two ends of the second reinforcing strip are bent and fitted to the sidewalls of the two outermost first fins.

[0010] The beneficial effects of this utility model are reflected in:

[0011] This invention uses positioning bands on the outer side of all fins to ensure that lateral forces are shared by all fins, avoiding individual fins from being subjected to force alone. These bands can change the fin resonant frequency, suppress vibration amplitude, effectively prevent fatigue fracture, and improve the structural strength and service life of the radiator.
