Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

A heat sink 20 according to an embodiment of the present invention is described below with reference to fig. 1 to 24, including: a radiator main body 21, and a spoiler 10.

Specifically, the heat sink main body 21 has a heat dissipation chamber 22 formed therein, and the heat sink main body 21 includes: the heat dissipation plate 24 and the heat dissipation structures 23, the heat dissipation structures 23 are arranged on the heat dissipation plate 24, and the heat dissipation structures 23 are located in the heat dissipation chamber 22; the spoiler 10 is disposed in the heat dissipation chamber 22, and the spoiler 10 includes: a plurality of vortex structures 200, a plurality of vortex structures 200 are located respectively between two adjacent heat radiation structure 23, vortex structure 200 vertical setting to be perpendicular with the fluid flow direction in the heat dissipation cavity 22, leave the clearance between the top of vortex structure 200 and the bottom of heating panel 24.

It can be understood that, during the use of the heat sink 20, a heat dissipation chamber 22 is formed in the heat sink body 21, the heat dissipation chamber 22 is suitable for the circulation of a heat dissipation fluid, and the heat dissipation fluid exchanges heat with the heat applied to the heat sink body 21 during the circulation process and brings the heat out of the heat sink 20 along with the circulation of the heat dissipation fluid, thereby forming the use performance of the heat sink 20. Meanwhile, the heat dissipation structure 23 is disposed on the heat dissipation plate 24 of the heat sink 20, and the heat dissipation structure 23 is suitable for increasing the heat exchange area to improve the heat dissipation effect of the heat sink 20.

It should be noted that, a flow-disturbing structure 200 is built in the heat-dissipating chamber 22, and the flow-disturbing structure 200 increases the flow velocity of the heat-dissipating fluid, so that the heat can be taken out from the heat sink 20 more quickly, and the heat-dissipating performance of the heat sink 20 is improved.

Specifically, the turbulent flow structure 200 may be a plurality of turbulent flow structures 200, so that the flow velocity of the heat dissipating fluid in the heat dissipating chamber 22 is faster, so that the heat can be brought out of the heat dissipating device 20 faster, so that the heat dissipating device 20 has higher heat dissipating performance, and a gap 26 is left between the turbulent flow structure 200 and the heat dissipating plate 24, because the gap 26 is formed between the top of the turbulent flow structure 200 and the bottom of the heat dissipating plate 24, the heat dissipating plate 24 at this position has higher heat, the gap 26 is formed between the top of the turbulent flow structure 200 and the bottom of the heat dissipating plate 24, when the heat dissipating fluid passes through the turbulent flow structure 200, a turbulent flow is generated, and the heat can be taken away more effectively by the turbulent flow, so as to improve the heat dissipating effect of the heat dissipating device 20.

The heat is transferred from the power device 25 to the heat dissipation plate 24, the heat is transferred from the heat dissipation plate 24 to the heat dissipation structure 23 and then transferred downwards, the actually hottest place is the lower surface of the heat dissipation plate 24, especially the place without the cylindrical heat dissipation structure 23 on the lower surface, the area on the heat dissipation plate 24 plus the heat dissipation structure 23, the original laminar flow ratio under the heat dissipation plate 24 is more, the spoiler 10 is used, the water flow becomes turbulent flow after passing, the proportion of the turbulent flow in that place can be seen, the effect of improving the heat dissipation is mainly generated in that place (the place without the cylindrical heat dissipation structure 23 on the lower surface of the heat dissipation plate 24) and not in the heat dissipation structure 23, because the heat dissipation structure 23 has the effect of the spoiler itself, the spoiler 10 generates 8% -10% effect, the turbulence is mainly generated in the place without the heat dissipation structure 23 of the heat dissipation plate 24 (when the power device 25 is right above, the place between the two heat dissipation structures 23 is the hot place), the spoiler 10 pushes a part of the fluid to that side, the sectional area becomes smaller, and the local speed increases.

The average velocity is shown to be reduced due to the increased proportion of turbulence, and it is due to the increased proportion that gives better heat dissipation.

The turbulent flow member 10 is added in the middle of the heat dissipation structure 23, that is, the turbulent flow structure 200 is added between the two heat dissipation structures 23, so that the space between the heat dissipation structures 23 is squeezed, the fluid moves to the place and is forced to be subjected to turbulent flow, the flow rate is suddenly increased, the fluid is in contact with the heat dissipation structures 23, the heat transfer is more severe, and the purpose of heat exchange enhancement is achieved. Therefore, after the spoiler 10 is added, the spoiler 10 can strengthen the heat exchange close to the water outlet, so that the uneven temperature distribution of the power device 25 is well improved, the current carrying capacity of the module is enhanced, and higher power density can be realized.

According to the heat sink 20 of the embodiment of the invention, the turbulent flow structure 200 is arranged in the heat dissipation chamber 22, the gap 26 is formed between the turbulent flow structure 200 and the heat dissipation plate 24, and when the heat dissipation fluid passes through the gap 26 between the turbulent flow structure 200 and the heat dissipation plate 24, turbulent flow can be generated to take away heat, so that the use performance of the heat sink 20 is improved. Meanwhile, the turbulent flow structure 200 disposed in the heat dissipation chamber 22 increases the flow rate of the heat dissipation fluid circulating in the heat dissipation chamber 22, so that the heat sink 20 has higher usability.

In some specific embodiments, the gap 26 is d, and d satisfies the relationship: d is more than or equal to 0.2mm and less than or equal to 5mm. It should be noted that the width of the gap 26 should not be too large or too small, if the gap 26 is too small, the flow rate of the heat dissipation fluid flowing in the gap 26 is small, and the heat dissipation fluid cannot generate a relatively effective turbulent flow to take away heat when passing through the gap 26, so that the heat dissipation performance of the heat sink 20 is not significantly improved, and if the gap 26 is too large, the flow rate of the heat dissipation fluid flowing in the gap 26 is slow, and the heat dissipation fluid cannot generate a turbulent flow capable of effectively improving the heat dissipation performance when passing through the gap 26. Therefore, the gap 26 is set between 0.2mm and 5mm, so that the heat dissipation fluid can be ensured to better circulate through the gap 26, and the heat dissipation performance of the heat sink 20 can be improved by reliable turbulence when circulating through the gap 26.

In some embodiments, spoiler 10 further comprises: the base plate 100, a plurality of vortex structures 200 set up on the base plate 100 and set up at the interval on the base plate 100. Specifically, a plurality of flow disturbing structures 200 are disposed on the bottom plate 100 and spaced apart from each other on the bottom plate 100, and the flow disturbing structures 200 are used for disturbing the heat dissipating fluid in the heat sink 20. The heat dissipating fluid includes a heat dissipating liquid and a heat dissipating gas.

It can be understood that the spoiler 10 is suitable for being constructed in the heat dissipation chamber 22 of the heat sink 20, the spoiler 10 includes a bottom plate 100 and a spoiler structure 200, the bottom plate 100 is suitable for being arranged opposite to the heat dissipation chamber 22 so as to allow the heat dissipation fluid to circulate in the heat dissipation chamber 22, and the spoiler structure 200 is suitable for being correspondingly arranged in the heat dissipation chamber 22 so as to disturb the heat dissipation fluid in the heat dissipation chamber 22 of the heat sink 20, so that the flow rate of the heat dissipation fluid is increased, so that the amount of heat that the heat dissipation fluid can take away is increased, and the heat dissipation performance of the heat sink 20 is increased.

Thus, the turbulent flow structure 200 is arranged on the bottom plate 100, so that the turbulent flow structure 200 is constructed in the heat dissipation chamber 22, and the turbulent flow structure 200 can disturb the heat dissipation fluid, so that the flow rate of the heat dissipation fluid in the heat dissipation chamber 22 is increased, and the heat dissipation performance of the heat sink 20 is improved.

In some embodiments, as shown in fig. 7 and 8, the turbulator structure 200 is configured as a cylinder; or the flow perturbation structure 200 includes: a cylindrical section 210 and a conical section 220, the cylindrical section 210 being connected between the base plate 100 and the conical section 220, the conical section 220 having a decreasing cross-sectional area in a direction away from the cylindrical section 210.

It can be understood that, constructing the spoiler structure 200 into a cylinder can facilitate the production and construction of the spoiler structure 200, and make the construction of the spoiler structure 200 on the bottom plate 100 more reliable, thereby improving the spoiler acceleration effect of the spoiler structure 200 on the heat dissipating fluid.

The cylindrical section 210 and the conical section 220 are adopted to form the spoiler structure 200, so that the conical section 220 can be constructed at the free end of the cylindrical section 210, and the conical section 220 can provide certain guiding performance due to the fact that the transverse sectional area of the conical section 220 decreases progressively in the direction away from the cylindrical section 210, so that the spoiler 10 can be conveniently assembled on the radiator 20.

In some embodiments, as shown in fig. 7-24, the spoiler 10 further comprises: the spoiler head 300, the spoiler head 300 is disposed on the spoiler structure 200.

In some embodiments, the spoiler head 300 is a solid circle, a hollow circle, a rectangle, or a parallelogram, as shown in fig. 9, 10, and 21. It is understood that the spoiler head 300 may be configured in the above-mentioned shape, and may be configured in other non-symmetrical patterns, so that the spoiler head 300 can occupy the space inside the heat dissipation chamber 22, so that the spoiler effect of the spoiler 10 on the heat dissipation fluid is improved, and the heat dissipation performance of the heat sink 20 is improved.

In some embodiments, as shown in fig. 11, 12, and 13, the spoiler head 300 has an arc shape with one end connected to an end of the spoiler structure 200; or the middle part of the arc is connected to the end part of the spoiler structure 200 and the two ends extend towards the direction far away from the bottom plate 100; or two turbulence heads 300 are provided, the two turbulence heads 300 are arranged on two opposite sides of the end part of the turbulence structure 200, and two arc-shaped ends are connected to one side of the end part of the turbulence structure 200.

It will be appreciated that by constructing the spoiler head 300 as an arc, the production materials are reduced as compared to a solid spoiler head 300, thereby reducing the production cost of the spoiler 10. The arc-shaped structure of the turbulence head 300 can improve the turbulence effect of the turbulence head 300 on the heat dissipating fluid circulating in the heat dissipating chamber 22. In addition, turbulence head 300 can set up two of relative setting, sets up two turbulence heads 300 on turbulence structure 200, can promote turbulence structure 200 to the fluidic vortex effect of heat dissipation of circulation in heat dissipation cavity 22 to let the radiating effect of radiator 20 obtain further promotion. Meanwhile, depending on the structure of the heat dissipation chamber 22 of the heat sink 20, the arc-shaped spoiler head 300 may be connected to one side or opposite sides of the end of the spoiler structure 200 to improve the spoiler effect of the spoiler 10 on the heat dissipation fluid.
