Description

Technical Field

[0001] The present invention relates to the technical field of temperature equalizing plate preparation, and in particular to a tubular temperature equalizing plate with unequal thickness and a boss and a preparation process thereof. Background Art

[0002] With the increasing heat flux density of electronic chips and the increase in power demand, traditional air cooling technology can no longer meet the heat dissipation needs of highly integrated electronic chips. Liquid cooling technology has gradually become the mainstream of the market. The current liquid cooling technology includes direct cooling and indirect cooling. Direct cooling is to fill the chassis with insulating liquid such as fluorinated liquid to directly contact the electronic chip for heat dissipation. This method is limited by the insulating liquid, is costly and difficult to maintain, and is rarely used in the market. Indirect cooling is to set a liquid flow channel inside the liquid cooling plate, and the fluid conducts heat through the contact between the liquid cooling plate and the electronic chip. Since direct contact between the fluid and the electronic chip is avoided, indirect cooling is more popular in the existing liquid cooling technology. However, the process of opening a liquid flow channel in the liquid cooling plate is relatively complicated and costly. In addition, the liquid cooling plate with a liquid flow channel is easily deformed by pressure during installation and use due to its low strength, which seriously affects the overall heat dissipation performance. In order to solve this problem, the existing technology increases the thickness of the liquid cooling plate to improve the installation strength. However, an overly thick liquid cooling plate cannot well guarantee the heat dissipation efficiency, resulting in low heat dissipation efficiency, and an overly thick size does not meet the market development needs.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling the reader to have a thorough understanding of one or more aspects of the invention, and these aspects of the present invention can be realized even without these specific details.

[0039] See also Figures 1 to 14The present invention provides a tubular temperature-averaging plate with unequal thickness and a boss and a preparation process thereof, and the technical solution is as follows:

[0040] like Figure 1-2 As shown, a tubular temperature equalizing plate with unequal thickness having bosses comprises a hollow tube body formed by connecting a sheet at both sides. The hollow tube body comprises an upper tube body and a lower tube body. A plurality of first bosses are arranged on the inner side of the upper tube body, and the plurality of first bosses are formed by rolling the upper tube body at one time. A plurality of second bosses corresponding to the first bosses are arranged on the inner side of the lower tube body, and the plurality of second bosses are formed by rolling the lower tube body at one time. The first bosses and the second bosses arranged correspondingly are fixedly connected. The radial dimensions of the first boss and the second boss gradually decrease from the bottom to the top, and the end faces of the tops of the first boss and the second boss are arranged horizontally. The end face of the top of the first boss is connected to the end face of the top of the second boss. By providing the first boss and the second boss, the installation strength of the upper tube body and the lower tube body is increased, so that the manufactured temperature equalizing plate is not easily deformed during installation and use, thereby avoiding the heat dissipation performance being affected by the deformation of the tube body. In addition, due to the provision of the first boss and the second boss, the tube body can be made very thin, so that an unequal thickness structure is formed between the boss and the rest of the tube body. The thinner tube body is more conducive to heat dissipation and has a certain strength, thereby ensuring the heat dissipation effect while ensuring the strength.

[0041] It should be noted that the first boss and the second boss are both formed by rolling by rolling equipment, such as Figure 3As shown, the rolling equipment includes an upper roller and a lower roller, and the upper roller is provided with a first boss rolling groove group for rolling the first boss. The first boss rolling groove group includes two rows of first boss rolling grooves arranged at intervals along the lateral direction of the upper roller. Each rolling groove row includes a plurality of first boss rolling grooves arranged at intervals along the circumferential direction of the upper roller, and the first boss rolling groove is used to roll out the first boss. In order to improve the uniformity of the overall strength of the tube body, the first boss is arranged in a long strip shape, and the axial direction of the first boss forms a certain angle with the axial direction of the tube body, and the angle is 15-45°. In the same row, two adjacent first bosses can be set in different axial directions to improve the uniformity of the strength distribution of the tube body. The upper roller is also provided with a second boss rolling groove group for rolling the second boss. The second boss rolling groove group is arranged at an interval with the first boss rolling groove group, and the interval is: the center line of the interval is the symmetry axis, and the second boss rolling groove group is arranged in an axisymmetric manner with the first rolling groove group. The second boss rolling groove group includes two rows of second boss rolling grooves arranged at intervals along the lateral direction of the upper roller, each second boss rolling groove row includes a plurality of second boss rolling grooves arranged at intervals along the circumferential direction of the upper roller, and the second boss rolling groove is used to roll out the second boss. The second boss rolling groove is arranged correspondingly to the first boss rolling groove, and the corresponding first boss rolling groove and the second boss rolling groove are arranged axially symmetrically, so that the first boss and the second boss arranged symmetrically can be prepared. A lower roller is arranged below the upper roller, and the surface of the lower roller is a smooth curved surface. When the sheet body passes between the upper roller and the lower roller, the sheet body is squeezed by the lower roller, so that the area where the upper roller is not provided with the first boss groove and the second boss groove squeezes the sheet body. When the sheet body is squeezed in this area, the squeezed area on the sheet body becomes thinner, and the area on the sheet body corresponding to the first boss groove and the second boss groove is not squeezed so as to maintain the thickness, forming the first boss and the second boss, that is, the thick tube body part, and the squeezed area forms a thin tube body part. The first boss and the second boss strengthen the overall strength of the tube body by the thick part, and the squeezed thin part can improve the heat dissipation performance. Moreover, the tube body can be made thinner and lighter, which is convenient for installation and has better heat dissipation performance.

[0042] The two ends of the upper tube body are bent inwardly to form a first bending portion, and the two ends of the lower tube body are bent inwardly to form a second bending portion, and the first bending portion is sealed and connected to the second bending portion. The first bending portion and the second bending portion can be pressed simultaneously on the upper and lower sides of one end by a stamping device, so that the upper and lower sides of the end are tightly attached, and then the upper and lower sides are welded at the tightly attached positions, and the other end is stamped and welded in the same way, so that the two ends are sealed to form a temperature equalizing plate. In the temperature equalizing plate, the connection of multiple first bosses and second bosses improves the overall strength of the temperature equalizing plate, so that the temperature equalizing plate will not be easily deformed during installation and use to affect the heat dissipation effect, thereby ensuring the heat dissipation efficiency.

[0043] Furthermore, a liquid absorbent core is provided on the inner wall of the upper tube body, the outer wall of the first boss and the second boss. The liquid absorbent core is based on the capillary effect and the principle of liquid dynamics. When the liquid contacts the surface of the liquid absorbent core, due to the tiny pore structure inside the liquid absorbent core, the liquid is quickly absorbed and diffused along the fiber network, forming a "wicking" phenomenon. This effect allows the liquid to flow back to the evaporation end under the action of gravity, thereby facilitating the transfer and circulation of heat. The liquid absorbent core includes a metal mesh type or a metal sintering type. The metal mesh type is to attach a metal wire mesh of a certain mesh number to the inner wall of the upper tube body and the outer wall of the dotting groove. The metal sintering type includes powder sintering and fiber sintering. By providing a liquid absorbent core, the heat transfer rate and coolant circulation are increased, and the heat dissipation efficiency is further improved.

[0044] like Figure 4 As shown, a heat dissipation fin is arranged on the outer side wall of the upper tube body, and the heat dissipation fin is fixedly connected to the upper tube body. The heat dissipation fin includes a first zigzag fin group and a second zigzag fin group, and the first zigzag fin group and the second zigzag fin group are alternately arranged along the transverse direction of the upper tube body. The first zigzag fin group includes a plurality of first zigzag fins arranged in sequence along the longitudinal direction of the upper tube body, and the plurality of first zigzag fins are sequentially connected as one body. The second zigzag fin group includes a plurality of second zigzag fins arranged in sequence along the longitudinal direction of the upper tube body, and the plurality of second zigzag fins are sequentially connected as one body. The crest width of the first zigzag fin is staggered with the crest width of the second zigzag fin. The heat dissipation fin is in contact with the upper tube body, and the heat of the upper tube body can be transferred to dissipate the heat, thereby improving the heat dissipation effect. The crest width of the first zigzag fin of the heat dissipating fin is offset from the crest width of the second zigzag fin, so that the first zigzag fin and the second zigzag fin form an offset gap, and air can flow through the offset gap, thereby improving the heat dissipation effect of the heat dissipating fin.

[0045] The present invention also discloses a preparation process of a tubular temperature-averaging plate with unequal thickness having a boss, the process comprising the following steps:

[0046] S1. Select a planar substrate and perform rolling along the longitudinal direction of the planar substrate to form a first boss group and a second boss group on one side of the planar substrate, wherein the first boss group and the second boss group are axially symmetrically arranged, wherein the first boss group includes at least one first boss column composed of a plurality of first bosses spaced apart along the longitudinal direction of the planar substrate, and the second boss group includes at least one second boss column composed of a plurality of second bosses spaced apart along the longitudinal direction of the planar substrate;

[0047] S2, rolling out curved connecting parts on both sides of the flat substrate after rolling, the connecting parts are bent toward the side with the boss, and then rolling the middle part of the flat substrate to make the connecting parts on both sides of the flat substrate close to each other to form a U-shaped material, and continue rolling until the connecting parts on both sides are in contact, and weld the connecting parts on both sides to form an O-shaped tube body;

[0048] S3, rolling the two opposite sides of the O-shaped tube body until the corresponding first bosses contact the second bosses, and the O-shaped tube body becomes an elliptical tube body, cutting the elliptical tube body to form tube body segments, cleaning the tube body segments, and checking for leaks;

[0049] S4, welding the contact point between the first boss and the second boss in the tube body section, then punching one end of the tube body section so that the upper and lower sides of the end are in close contact, and welding the contact part to form a semi-sealed tube body section, and passing liquid into the open end of the semi-sealed tube body section for water test. After the water test, vacuuming the semi-sealed tube body section from the open end and injecting cooling liquid;

[0050] S5. Punch and weld the open end of the semi-sealed tube section to seal both ends of the tube section to form a temperature-averaging plate. Select a heat sink fin, place the heat sink fin close to an outer wall of the temperature-averaging plate, weld the heat sink fin at the contact point with the temperature-averaging plate, and fix the heat sink fin to the outer wall of the temperature-averaging plate.

[0051] The above preparation process is simple, the boss only needs to be rolled once, and there is no need to connect different columnar supports, which improves the preparation efficiency of the heat spreader and reduces the process cost output. In addition, the process can be used to prepare a heat spreader with better heat dissipation performance.

[0052] The present invention carries out comparative experiment:

[0053] Under the same outer dimensions (120mm×26mm T=2mm), compared with aluminum plate, O-tube without internal support and harmonica tube with internal columnar support, using the same heat source, heat source conditions: size (10mm×10mm) heat flow (50w), no cooling conditions, two seconds transient performance, the following Table 1 is obtained:

[0054] Table 1

[0055]

[0056] In Table 1, Control Example 1 is an aluminum plate, Control Example 2 is an O-type tube, Control Example 3 is a harmonica tube, and Example 1 is a temperature averaging board of the present invention. As can be seen from Table 1, the temperature averaging board of the present application has a significant drop in heat source temperature compared to Control Examples 1-3, a significant heat dissipation effect, a smaller weight, and better heat dissipation performance. Figure 5-8 shown.

[0057] Example 2

Different from Example 1, in this embodiment, the heat dissipation fins include a third zigzag fin group, the third zigzag fin group includes a plurality of third zigzag fins arranged in sequence along the longitudinal direction of the upper tube body, the plurality of third zigzag fins are sequentially connected as one, and the crests of the third zigzag fins are arranged in a wavy shape along the transverse direction of the upper tube body. The wavy heat dissipation fins increase the space for air circulation, so that the air can take away more heat from the heat dissipation fins, thereby improving the heat dissipation effect.

[0059] Example 3

[0060] like Fig.10 As shown, the present invention provides a tubular temperature-averaging plate with unequal thickness having a boss and a preparation process thereof. Different from Example 1, in this embodiment, the heat dissipation fin includes a fourth zigzag fin group, and the fourth zigzag fin group includes a plurality of fourth zigzag fins arranged in sequence along the transverse direction of the cavity tube body, and the plurality of fourth zigzag fins are sequentially connected as one, and the crest of the fourth zigzag fin is arranged in a straight line along the longitudinal direction of the cavity tube body. The straight-line heat dissipation fins improve the heat dissipation efficiency, but are simple to manufacture, easy to produce, and improve production efficiency.

[0061] This embodiment has made comparative experiment:

[0062] Under the same outer dimensions (120mm×26mm T=2mm), compared with the combination of aluminum plate and heat sink fin, the combination of O-tube and heat sink fin without internal support, and the combination of harmonica tube and heat sink fin with internal columnar support, the same heat source is used, the heat source conditions are: size (10mm×10mm) heat flow (50w), no cooling conditions, two seconds transient performance, and the following Table 2 is obtained:

[0064]

[0065] In Table 2, Control Example 1 is a combination of aluminum plate and heat sink fins, Control Example 2 is a combination of O-tube and heat sink fins, Control Example 3 is a combination of harmonica tube and heat sink fins, and Example 1 is a combination of the temperature averaging plate and heat sink fins of the present invention. It can be seen from Table 2 that the combination of the temperature averaging plate and heat sink fins of the present application has a significant drop in heat source temperature and a significant heat dissipation effect compared to Controls 1-3, and is lighter and has better heat dissipation performance. The simulation cloud diagram is shown in FIG. Figure 11-14 shown.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
