Description

Technical Field

[0001] The utility model specifically relates to a metal braided radiator and a braided radiator. Background Art

[0002] Electronic components will inevitably generate a certain amount of heat during operation. However, if the heat generated by the electronic components during operation cannot be dissipated in time, the operating speed and working performance of the electronic components will be greatly affected. What is more serious is that the electronic components may be burned out due to overheating.

[0003] In the prior art, in order to enable electronic components to work faster, more stably and for a longer life, radiators are generally used to dissipate heat from electronic components. There are two main technologies for heat dissipation of electronic components: active cooling and natural cooling. Active cooling technology generally uses a fan or blower to force the cooling medium to flow through the heat exchange surface, and removes the heat generated by the electronic equipment through forced convection. Natural cooling technology removes the heat generated by electronic equipment through natural convection and thermal radiation of the air. Compared with active cooling, natural cooling does not require moving parts such as fans or blowers, and has the outstanding advantages of high reliability and quietness.

[0004] For example, a domestic invention application with application number 201510734373.6 is entitled: A woven heat sink for electronic components. The structure disclosed in the invention application is: including a base layer, which is flexible; and a heat dissipation layer, which is formed on a surface of the base layer; wherein the base layer is made of cross-woven metal wires; and the heat dissipation layer is formed by stretching and bending part of the metal wires in the base layer. This structure effectively solves the technical problems mentioned above.

[0005] Users expect to further improve the heat dissipation effect based on this structure, help improve adhesion and water adsorption, and be suitable for electronic components that generate large amounts of heat. Summary of the invention

To this end, one purpose of the utility model is to provide a metal braided heat sink and a braided heat sink to further improve the heat dissipation effect, help improve the adhesion and the amount of water adsorbed.

[0007] A metal braided heat sink according to the utility model comprises a plurality of heat sink metal wires braided into a tubular structure, wherein the heat sink metal wires have an outer peripheral base surface, and the outer peripheral base surface is processed with an ectopic heat absorption portion located adjacent to the outer peripheral base surface.

[0008] Specifically, the ectopic heat absorption portion is composed of convex portions arranged outside the outer peripheral base surface, and gaps are left between the convex portions.

[0009] Specifically, the ectopic heat absorption portion is composed of recessed portions arranged in the outer peripheral base surface, and the recessed portions are distributed at intervals.

[0010] Specifically, the inner bottom surface of the ectopic heat absorption portion is arc-shaped.

[0011] The utility model discloses a braided radiator using the above-mentioned metal braided radiator, comprising a tube body, and heat dissipation metal wires are distributed on the inner wall of the tube body.

[0012] Specifically, the heat dissipation metal wires are woven into a mesh layer.

[0013] Alternatively, the heat dissipating metal wires are woven into layers.

[0014] Specifically, the tube body is in a square shape, with gaps between the sheets, and the sheets are fixed in the tube body by resin.

[0015] The beneficial effects of the utility model are as follows: the structure is processed with an ectopic heat absorption part located on the adjacent side of the outer peripheral base surface through the outer peripheral base surface, the ectopic heat absorption part increases the overall heat dissipation area, and the liquid slows down when flowing through the ectopic heat absorption part, which fully improves the heat exchange rate and improves the heat dissipation and water adsorption effect of the heat dissipation metal wire; in addition, the ectopic heat absorption part increases the roughness of the surface of the heat dissipation metal wire, thereby helping to improve the adhesion.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Reference below Figures 1 to 6 Description A metal braided heat sink according to an embodiment of the utility model includes a heat sink metal wire 1, including a plurality of heat sink metal wires 1 for braiding into a tube structure, the heat sink metal wire 1 having an outer peripheral base surface 4, the outer peripheral base surface 4 being processed with an ectopic heat absorption portion located adjacent to the outer peripheral base surface 4. During the description, the outer peripheral base surface 4 refers to the surface of the heat sink metal wire 1 as the base surface, and the ectopic refers to a position located outside the outer peripheral base surface 4 or located inside the outer peripheral base surface 4.

[0026] In this structure, the peripheral base surface 4 of the heat dissipation metal wire 1 is processed with an ectopic heat absorption part located on the adjacent side of the peripheral base surface 4. The ectopic heat absorption part increases the overall heat dissipation area, and the liquid slows down when flowing through the ectopic heat absorption part, which fully improves the heat exchange rate, thereby improving the heat dissipation and water adsorption effect of the heat dissipation metal wire; in addition, the ectopic heat absorption part increases the roughness of the surface of the heat dissipation metal wire, thereby improving the adhesion.

[0027] The heat dissipation wire 1 is an oxygen-free steel wire, a stainless steel wire or a copper wire. The diameter of the heat dissipation wire 1 is 0.02 to 0.05 mm. The width of the ectopic heat absorption part is 1 μm.

[0028] The structure of the ectopic heat absorption part is as follows.

[0029] First embodiment.

[0030] like Figure 1 As shown, the ectopic heat absorption portion is composed of convex portions 101 arranged outside the outer peripheral base surface 4, and gaps are left between the convex portions 101.

[0031] Second embodiment.

[0032] like Figure 2 As shown, the ectopic heat absorption portion is composed of recesses 102 arranged in the outer peripheral base surface 4, and the recesses 102 are distributed at intervals.

[0033] The above two structural modes can increase the contact area with the liquid. In addition, the inner bottom surface of the ectopic heat absorption part of this structure is in an arc shape, which can further increase the contact area with the liquid.

[0034] like Figures 3 to 6 As shown, the utility model discloses a braided heat sink using the above-mentioned metal braided heat sink, comprising a tube body 2 , and heat dissipation metal wires 1 distributed on the inner wall of the tube body 2 .

[0035] The heat dissipation wire 1 is inserted into the heat source 3 or adhered to the surface of the heat source 3, and the heat source transfers heat to the heat dissipation wire 1. The heat dissipation wire 1 contacts the liquid to implement heat exchange and achieve the cooling effect.

[0036] like Figure 3 and Figure 4 As shown, more specifically, the heat dissipation metal wire 1 is woven into a mesh layer. Figure 3 As shown, the network layer is a layer setting; Figure 4 As shown, the mesh layer is a two-layer arrangement. In addition, the mesh layer is tightly attached to the inner wall of the tube body 2, further improving the overall heat conduction effect. The mesh layer acts as a resistance, slowing down the speed of liquid reflux and improving the liquefaction effect. To summarize the above, the braided radiator utilizes the heat dissipation metal wires 1 to interlace with each other at the corresponding two ends so that the heat dissipation metal wires 1 form two intersections, or to interlace with each other at the corresponding four ends so that the mesh layer forms four intersections, thereby reducing the number of the intersections, thereby effectively improving the deformation pre-measurement of the mesh layer bending, so that the mesh layer can be tightly attached to the inner wall of the tube body 2, while increasing the contact area between the mesh layer and the tube body 2 as a whole, further improving the overall heat conduction effect, and greatly reducing the resistance generated when the liquid flows.

[0037] like Figure 5 As shown, the heat dissipation wire 1 is woven into a sheet layer, the tube body 2 is in a square shape, and there is a gap 201 between the sheets. The sheets are fixed in the tube body 2 by resin. The sheets can be connected to a plurality of heat sources to implement heat transfer. The liquid is located in the gap 201, and the liquid absorbs the heat emitted by the sheet layer.

[0038] The sheet is fixed in the tube body 2 by resin, thereby limiting the position of the sheet. The liquid is located in the gap 201, and the liquid absorbs the heat emitted by the sheet.

[0039] like Figure 6 As shown, the surface of the heat source 3 of this structure is provided with a tube body 2, and the heat dissipation metal wire 1 is distributed on the inner wall of the tube body 2. Liquid is input into the tube body 2, and the liquid contacts the heat dissipation metal wire 1;

[0040] In addition, the pipe body 2 and the heat source 3 are sealed by a sealant to prevent leakage. In addition, the liquid can be selected according to the working temperature, such as water, methanol, ethanol, acetone, mercury and alcohol.

[0041] When the heat source 3 absorbs heat and transfers it to the heat dissipation wire 1, the heat dissipation wire 1 heats the liquid to evaporate and vaporize. At the same time, in the process of moving to the other end of the tube body 2, the heat is dissipated outward and gradually condenses and liquefies. The liquefied liquid flows back to one end of the tube body 2 through the heat dissipation wire. Such a phase change cycle can effectively reduce the temperature.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
