Embodiment 1

[0043] see figure 1 , a low-resistance semicircular embossed fin for a cooler, comprising a semicircular structure fin 6 and an embossed 1, the opening direction of the embossed 1 is consistent, and is arranged at intervals on the wing-shaped side of the fin 6, and the embossed The height of the mark 1 is 1 / 6 to 1 / 2 of the height of the section of the fin channel, and a plurality of fins 6 are arranged in parallel to form an air flow channel 5 between the fins 6. Internally generate vibration and disturbance to the air medium, and achieve ideal heat mixing effect and heat transfer capacity under the condition of low internal resistance.

[0044] The distance between the raised marks 1 is 6-12mm, the distance between the raised marks 1 near the entrance 4 of the fin channel and the entrance 4 of the fin channel is 10-15mm, and the arrangement density of the semicircular raised marks can be adjusted. The basis for adjustment is the total pressure level of the fan. If the total ...

Embodiment 2

[0072] see figure 2 , a cooler with low extension resistance pressure prismatic embossed fins, including fins 6, a plurality of fins 6 are arranged in parallel, air flow channels 5 are formed between the fins 6, and the fin-shaped sides of the fins 6 are arranged at intervals There are convex marks 1 with the same opening direction, the height of the convex marks 1 is 1 / 6~1 / 2 of the section height of the air flow channel 5, and the convex marks 1 are used to generate vibration and disturbance to the air medium in the air flow channel 5 Function, to achieve ideal heat mixing effect and heat transfer capacity under the condition of low internal resistance.

[0073] Convexity 1 is an obtuse prismatic structure, which is used to change the cross section of the flow channel. The convexity is selected with an appropriate shape kurtosis to form an intermittent nozzle effect and turbulence effect, which makes the air flow disturbance of the cold medium and destroys the effect of the ...

Embodiment 3

[0091] see image 3 , a low-resistance symmetrical embossed fin for a cooler, including fins 6, a plurality of fins 6 are arranged in parallel, and air flow channels 5 are formed between the fins 6, and the wing-shaped sides of the fins 6 are arranged at symmetrical intervals Convex marks 1 with opposite opening directions. The height of the protruding marks 1 is 1 / 6~1 / 2 of the section height of the air channel 5. The protruding marks 1 are used to excite and disturb the air medium in the air channel 5. Realize the ideal heat mixing effect and heat exchange capacity under the condition of low internal resistance.

[0092] Protrusion 1 is a triangular prism structure, which is used to change the cross section of the flow channel. The convex mark selects an appropriate shape kurtosis to form an intermittent nozzle effect and turbulence effect, which makes the air flow disturbance of the cold medium and destroys the effect of the boundary laminar flow , allowing the air stream t...

Abstract

The invention discloses a low-chucking fin for a cooler. The low-chucking fin comprises a plurality of fin bodies in parallel, an air passage used for air flowing is formed between every two fin bodies, a plurality of protruding marks are arranged on the fin-shaped side face of each fin body at intervals, the height of the protruding marks is 1 / 6-1 / 2 of the height of the cross sections of the airpassages, and the protruding marks are used for generating shock excitation and disturbance effects on air media in the air passages. The low-chucking fin for the cooler is simple in structure, reasonable in design, high in capacity of heat transmission, easy to machine and wash and long in service life.

Description

technical field [0001] The invention belongs to the technical field of fins for heat dissipation of coolers, and in particular relates to a low-resistance fin for coolers. Background technique [0002] The basic function of the cooler fins is to support the fins, conduct heat, and establish heat transfer carriers and heat transfer conditions for hot and cold media. The form of fin design needs to take into account factors such as heat exchange capacity, manufacturing cost, cooler operating life, process resistance, heat exchange efficiency, equipment volume, and installation method. [0003] The existing fin shape design is often most concerned with the heat transfer intensity and production cost. Based on these considerations, the fins of the cooler will be designed with high resistance along the way and a complex structure, so that the highest possible heat transfer per unit area can be achieved. Thermal intensity, but also can reduce the size of the cooler. After the co...
