D-type dotting unequal-thickness structure collecting pipe

Abstract

The utility model discloses a D-shaped dotting unequal-thickness structure collecting pipe, and relates to the technical field of vehicle heat exchangers. Comprising a pipe body with a D-shaped section; by means of the flow channel structure formed by the multiple internal protruding points, when outer-layer fluid enters the flow channel structure in a turbulent flow mode, the outer-layer fluid is continuously acted by the internal protruding points, and therefore vortexes are gradually widened; the internal protruding points are located on the inner wall of the pipe body to form a non-equal-thickness pipe body structure. And the plurality of internal convex points form a multi-column structure and are distributed on the inner wall of the pipe body. When outer-layer fluid enters the flow channel structure in a turbulent flow state, the inner convex points continuously interfere with the fluid, so that vortexes of the fluid are gradually widened, and when the flow speed reaches a certain level, the fluid is in a disordered flowing state, so that heat transfer or full mixing is facilitated, and the heat exchange area of the inner side is increased; under the condition that the external size of the D-shaped collecting pipe is kept consistent, the D-shaped collecting pipe with the internal convex points and different thicknesses has a larger inner surface area, so that the heat exchange amount of the D-shaped collecting pipe is improved.

Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle heat exchanger technical field, concretely relates to a D type dotting unequal thick structure collecting pipe. BACKGROUND

[0002] With the rapid development of the automobile industry, the technology of heat exchange equipment is changing day by day, constantly promoting the progress of the industry. As one of the widely used pipe shapes in the current automobile heat exchanger industry, the optimization and promotion of the performance of D type collecting pipe is particularly important. However, the traditional D type collecting pipe design has a significant defect, that is, its inner wall is smooth without turbulence structure, which greatly limits its heat exchange effect, so that the heat exchange efficiency is not satisfactory. Therefore, how to effectively improve the heat exchange capacity of D type collecting pipe in limited space has become a technical problem to be solved.

[0003] On the other hand, in the design of existing D type collecting pipe, in order to ensure the integrity and strength of the structure, avoid damage or leakage and other problems in the use process, the thickness of the pipe wall is often set to be relatively large. Although this method enhances the durability and safety of the collecting pipe to a certain extent, it also brings the problems of increased material consumption and rising material cost in the manufacturing process. This not only increases the production cost of the product, but also poses a certain challenge to the rational use of resources and the sustainable development of the environment. SUMMARY

[0004] The utility model aims at providing a D type dotting unequal thick structure collecting pipe, which greatly improves the heat dissipation efficiency of the existing D type collecting pipe and appropriately enhances the structural strength under the premise of ensuring safety.

[0005] To achieve the above-mentioned purpose, the application provides a D type dotting unequal thick structure collecting pipe, which comprises:

[0006] The pipe body has a D-shaped cross section;

[0007] The flow channel structure formed by the plurality of internal convex points causes the vortex to gradually widen when the outer fluid enters the flow channel structure in the form of turbulent flow.

[0008] The internal convex points form a non-equal thick pipe body structure on the inner wall of the pipe body.

[0009] In one embodiment, the plurality of internal convex points form a plurality of column structures distributed on the inner wall of the pipe body.

[0010] In one embodiment, the directions of the adjacent two internal convex points on each column structure are different, that is, they are distributed in the shape of "eight".

[0011] In one embodiment, the internal protrusions on two adjacent columns and the same ring line are arranged in an "eight" shape structure.

[0012] In one embodiment, the multiple column structures are arranged in a spiral shape on the inner wall of the pipe body.

[0013] In one embodiment, the internal protrusions on each column structure are arranged in the same direction and are inclined.

[0014] In one embodiment, the internal protrusions on each column structure are arranged in an irregular direction.

[0015] In one embodiment, the internal protrusions on the adjacent column and the same ring line are arranged in the same direction.

[0016] In one embodiment, the pipe body has 1-3 side walls arranged with flow channel structures formed by internal protrusions.

[0017] In one embodiment, a plurality of flat tube holes are formed on one side wall of the pipe body.

[0018] The above technical scheme of the utility model has the advantages compared with the prior art: 1. A plurality of internal protrusions are arranged on the inner wall of the pipe body of the D-shaped manifold, which can change the flow channel structure, which is beneficial to heat transfer or full mixing, thereby increasing the heat exchange area on the inner side.

[0019] 2. Under the condition that the external dimensions of the D-shaped manifold remain unchanged, compared with the traditional equal-thickness D-shaped manifold, the D-shaped manifold with internal protrusions and unequal thickness has a larger internal surface area, thereby improving the heat exchange capacity.

[0020] 3. The internal protrusions on the inner wall of the pipe body enhance the structural strength to a certain extent, ensure the pressure resistance, and prolong the service life of the radiator.

[0021] 4. On the premise of ensuring the required strength, by reducing the wall thickness of the pipe body, the purpose of saving material cost can be achieved. BRIEF DESCRIPTION OF DRAWINGS

[0032] Please refer to Figures 1-2 The embodiment provides a D-shaped dotting unequal thickness structure current collecting pipe, which comprises:

[0033] The pipe body has a D-shaped cross section, and the thickness is smaller than the thickness of a conventional pipe body.

[0034] The flow channel structure formed by the plurality of internal protrusions can interfere with the fluid in a turbulent flow state to make the vortex of the fluid gradually widen, so that the fluid can be in a disordered flow state when the flow rate reaches a certain level, which is beneficial to heat transfer or mixing, thereby increasing the heat exchange area on the inner side.

[0035] The internal protrusions are arranged on the inner wall of the pipe body to form a non-equal-thickness pipe body structure.

[0036] In the present application, the D-shaped manifold is internally designed with dotting protrusions, which not only increase the internal surface area of the manifold, but also effectively improve the heat exchange capacity, thereby improving the heat exchange efficiency. To some extent, it can also enhance the pressure strength and prolong the service life of the radiator. On the basis of ensuring the required strength, by reducing the wall thickness of the pipe body, the purpose of saving material cost can also be achieved.

[0037] As a preferred embodiment provided by the present embodiment, the plurality of internal protrusions form a plurality of column structures and are arranged on the inner wall of the pipe body.

[0038] As a preferred embodiment provided by the present embodiment, as shown in Figure 3 , the directions of the adjacent two internal protrusions on each column structure are different, i.e., in the shape of an "eight". This not only improves the mixing uniformity and heat exchange efficiency of the fluid, but also helps to reduce the deposition and scaling of the fluid in the manifold, thereby prolonging the service life of the equipment.

[0039] As a preferred embodiment provided by the present embodiment, as shown in Figure 4 , the internal protrusions on the adjacent two columns and the same ring line are arranged in the shape of an "eight". When the fluid flows through the protrusions in the shape of an "eight", the fluid can be effectively guided to different flow directions, thereby promoting the mixing of the fluid and the formation of turbulent flow.

[0040] As a preferred embodiment provided by the present embodiment, the plurality of column structures are arranged in a spiral shape on the inner wall of the pipe body to optimize the fluid flow performance.

[0041] As a preferred embodiment provided by the present embodiment, the directions of the internal protrusions on each column structure are the same, and are arranged in an inclined manner. The inclination angle can be set as required. Such a design not only enhances the fluid dynamics performance of the manifold, but also ensures that the fluid can be distributed and conducted more smoothly and efficiently when flowing through.

[0042] As a preferred embodiment provided by the present embodiment, the directions of the internal protrusions on each column structure are irregularly distributed, and the angles of the internal protrusions are different. Such a design can increase the disturbance of the fluid in the manifold.

[0043] As the preferred embodiment provided by the embodiment, the directions of the internal convex points arranged on the same ring line and one column apart are the same, which can more effectively guide the fluid to turbulent mixing, reduce the flow resistance, and improve the heat exchange efficiency.

[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, 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.
