For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0035] Please refer to Figures 1-3 , the embodiment provides a D-shaped tube structure for a heat sink, comprising:
[0036] The pipe body has a D-shaped cross section and a thickness thinner than that of a conventional thickness.
[0037] A plurality of uneven dotting structures, the dotting structure has an outer concave point and an inner convex point, the inner convex point is arranged inside the pipe body, the outer concave point is arranged outside the pipe body, and the outer concave point and the inner convex point are arranged one by one.
[0038] The flow channel structure is formed by the plurality of inner convex points. When the outer fluid enters the flow channel structure in a turbulent flow state, the inner convex points will continuously interfere with the fluid, making the vortex gradually widen. When the flow rate reaches a certain level, the fluid will be in a disordered flow state, which is beneficial to heat transfer or realizes sufficient mixing, thereby increasing the heat exchange area on the inner side.
[0039] In the present embodiment, as Figure 4 shown, each uneven dotting structure has the same shape, which is a semispherical shape, and the plurality of inner convex points form a multi-row structure distributed on the inner wall of the pipe body. It should be noted that the radius of a single semispherical dotting structure is r, and the surface area of a single semispherical surface is 4πr 2 / 2. The D-shaped tube has n uneven dotting structures, i.e. the surface area of a single dotting position is 2nπr 2 . The dotting-replaced position of the traditional smooth surface D-shaped tube can be approximately regarded as a circular plane, and the surface area of all dotting-replaced positions is nπr 2Therefore, under the condition of the same size of the D-tube itself, the surface area of the D-tube with the circular dotting structure is larger than that of the traditional smooth D-tube, and the surface area of the structure is about nπr 2 The heat exchange area of the D-tube is greatly increased, and the heat exchange efficiency is improved. Meanwhile, the multi-column structure forms a reinforcing rib, increases the structural strength, ensures the pressure resistance, and prolongs the service life of the radiator.
[0040] In the embodiment, each of the uneven dotting structures has the same shape, which is a long circle. The plurality of inner convex points form a multi-column structure and are distributed on the inner wall of the tube body. As shown in Figure 5 , the inner convex points on adjacent two columns and in the same ring line are arranged in an "eight" shape structure. The directions of the adjacent two inner convex points on each column structure are different, that is, they are arranged in an "eight" shape, as shown in Figure 6 The above arrangement not only improves the uniformity of fluid mixing and the heat exchange efficiency, but also helps to reduce the deposition and fouling of fluid in the header, prolonging the service life of the equipment. The inner convex points on each column structure can also be arranged in the same direction, which is inclined. The inclination angle can be set according to the needs. Such design not only enhances the fluid dynamics performance of the header, but also ensures that the fluid can be distributed and conducted more smoothly and efficiently when flowing.
[0041] In the embodiment, the plurality of uneven dotting structures are distributed in a spiral shape on the inner wall of the tube body to optimize the fluid flow performance.
[0042] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
