Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiators, and more particularly to the field of heat pipe technology, specifically a lightweight, fast-cooling, dotted composite pipe. Background Technology
[0002] Radiators are commonly used cooling devices in automobiles and construction machinery. A radiator consists of water chambers at both ends and multiple cooling pipes passing through the water chambers. Liquid enters the cooling pipes from the water inlet side chamber and is cooled by the cooling pipes.
[0003] Current heat pipes are usually flat tubes with a long cross-section. In order to allow water to flow in various parts of the cross-section, fins are usually inserted at both ends of the heat pipe, which divides the end of the heat pipe into multiple cavities. This allows the liquid to be dispersed into each cavity, achieving the best heat dissipation effect. However, setting fins at both ends increases the weight of the heat pipe and reduces the water flow to some extent, affecting the cooling effect. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a lightweight, rapid-cooling, dotting composite pipe.
[0005] This utility model is achieved through the following technical solution: a lightweight, rapid-cooling, dotted composite tube is provided, including a tube body. The tube body includes a front aluminum plate and a back aluminum plate that are parallel to each other. The two ends of the front aluminum plate and the back aluminum plate are connected in the width direction. The front aluminum plate is provided with a plurality of front embossed protrusions that protrude into the tube body. The back aluminum plate is provided with a plurality of back embossed strips that extend along the length direction of the tube body. The back embossed strips are connected to the front embossed protrusions. A wavy fin is inserted into the interior of one end of the tube body.
[0006] As an optimization, the back aluminum plate is provided with multiple back embossings that protrude into the tube body, and the back embossings are connected to the front embossings.
[0007] As an optimization, both the back embossing and the front embossing are circular embossing.
[0008] As an optimization, multiple back protrusions are arranged at equal intervals along the width direction of the back aluminum plate, and back protrusions are provided between adjacent back protrusions.
[0009] As an optimization, the length of the back ridge is 0.7-0.9 times the length of the tube body, and the distance between the end of the back ridge away from the fin and the end of the tube body is 3-10 mm.
[0010] As an optimization, one end of the front aluminum plate and the back aluminum plate in the width direction is integrally connected by a multi-layer folding structure, and the other end is connected by a multi-layer connecting structure.
[0011] The beneficial effects of this utility model are as follows: This utility model provides a lightweight, rapid-cooling, dotted composite pipe. By setting fins on the water inlet side, the liquid is dispersed to various cross-sectional positions inside the pipe body. After the liquid passes through the internal protrusions, it forms turbulence. The turbulent liquid then comes into full contact with the pipe body, achieving sufficient heat exchange and improving the cooling effect of the heat dissipation pipe. In addition, it achieves lightweight design. This utility model can be applied to various types of radiators, improving the heat dissipation effect of the radiators. Attached Figure Description

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0022] like Figures 1-7 As shown, the present invention discloses a lightweight rapid cooling dotting composite tube, which includes a tube body formed by bending a single aluminum plate. The tube body includes a front aluminum plate 1 and a back aluminum plate 8 that are parallel to each other. The two ends of the front aluminum plate 1 and the back aluminum plate 8 are connected in the width direction to form a rectangular cavity inside the tube body.
[0023] To achieve the formation of a tube from a single aluminum sheet, in this embodiment, one end of the front aluminum sheet 1 and the back aluminum sheet 8 in the width direction is integrally connected by a multi-layer folding structure 3, as shown in the figure below. Figure 2 As shown, the front aluminum plate 1 and the back aluminum plate 8 are formed by folding the aluminum plate multiple times in the middle, with an odd number of folds. In this embodiment, the multi-layer folding structure 3 is folded 5 times, thus forming a 6-layer structure at the multi-layer folding structure 3.
[0024] The other ends of the front aluminum plate 1 and the back aluminum plate 8 are connected by a multi-layer connection structure 4. This connects the two ends of the aluminum plates to form a closed-loop structure, as shown in the multi-layer connection structure 4. Figure 2 As shown, a U-shaped structure is folded out on the front aluminum plate 1, and a double-layer structure is folded out on the back aluminum plate 8. The double-layer structure is inserted into the U-shaped structure to form a 6-layer structure, thus achieving connection.
[0025] The tube body has wavy fins 5 inserted inside one end, and the cross-section of the fins is as shown in the figure. Figure 3 As shown, its cross-section installed inside the pipe is as follows: Figure 2 As shown, the tube body is divided into multiple cavities by fins 5. In this embodiment, fins 5 are inserted at the end of the tube body on the liquid inlet side, thereby diverting the liquid on the liquid inlet side.
[0026] The front aluminum plate 1 has multiple front embossing 2 protruding into the tube body. The front embossing 2 is a recess formed by stamping on the front aluminum plate 1. In this embodiment, the front embossing 2 is a circular embossing, that is, it is stamped by a circular punch.
[0027] The back aluminum plate 8 has multiple raised back embossings 7 protruding into the tube body. In this embodiment, the raised back embossings 7 are also circular and have the same shape as the front embossings 2. Figure 7 As shown, the back embossing 7 is connected to the front embossing 2.
[0028] The back aluminum plate 8 has multiple back protrusions 6 extending along the length of the tube. These back protrusions 6 are elongated recesses formed by stamping onto the back aluminum plate 8. The width of the back protrusions 6 is the same as the diameter of the front protrusions 2, and... Figure 6 As shown, the raised strip 6 on the back is connected to the raised strip 2 on the front.
[0029] Multiple back protrusions 6 are arranged at equal intervals along the width direction of the back aluminum plate 8, and back protrusions 7 are provided between adjacent back protrusions 6.
[0030] The front embossing 2, the back embossing 7, and the back embossed strip 6 are all set in the area without fins 5. The length of the back embossed strip 6 is 0.7-0.9 times the length of the tube body, and the distance between the end of the back embossed strip 6 away from the fins 5 and the end of the tube body is 3-10mm.
[0031] Each back ridge 6 connects to a row of multiple front ridges 2, and the ends of all front ridges 2 are connected to back ridges 7 or back ridges 6, thereby achieving end support during stamping.
[0032] How to use this utility model:
[0033] In use, one end of the composite tube equipped with fins 5 is inserted into the water chamber on the liquid inlet side, and the other end is inserted into the water chamber on the liquid outlet side. The liquid flows into the tube body from the multiple cavities separated by the fins, so that the liquid is dispersed to various cross-sectional positions inside the tube body. When flowing in the tube body, the liquid forms turbulence after passing through the front convex 2, the back convex 7 and the back convex strip 6. The turbulent liquid comes into full contact with the tube body, and performs full heat exchange, improving the cooling effect of the heat dissipation tube. In addition, the thickness of the cavity at the back convex strip 6 position is only half of the original, thus achieving a certain flow diversion effect, thereby eliminating the need for fins on the liquid outlet side. At the same time, the back convex strip 6 improves the bending resistance of the composite tube in the length direction.
