Description

Technical Field

[0001] The present disclosure relates to the technical field of radiator manufacturing, and in particular to a water nozzle riveting welding structure of a liquid cooling plate. Background Art

[0002] In electric vehicles, the heat dissipation efficiency of the battery directly affects the service life of the vehicle. In order to speed up the heat dissipation efficiency of the battery and improve the performance of the vehicle, some manufacturers have made further research and development.

[0003] For example, Chinese patent document CN112490534A discloses an integrated hot and cold liquid cooling plate, which includes an upper flat plate, a lower flow channel plate is arranged under the upper flat plate, the gap between the lower flow channel plate and the upper flat plate constitutes a closed serpentine flow channel, and a water inlet and a water outlet are respectively arranged at the two ends of the serpentine flow channel at the top of the upper flat plate, cold water enters the flow channel from the water inlet, and water is discharged from the water outlet to realize circulating liquid cooling; two PTC heating cores are arranged at the interval of the serpentine flow channel at the bottom of the upper flat plate; connecting wires are connected to the sides of the two PTC heating cores, and the two connecting wires are connected to the power terminals for power connection.

[0004] However, the design of the above-mentioned integrated cold and hot liquid cooling plate has the following problems:

[0005] The above-mentioned integrated hot and cold liquid cooling plate is used to place batteries. Although the circulating heat dissipation of the batteries can be achieved through the water inlet and outlet nozzles on the liquid cooling plate, the water nozzles are usually installed on the liquid cooling plate by riveting and welding. During this process, the water nozzles are usually riveted into the welds of the liquid cooling plate by knocking. During the knocking process, the force is difficult to control, so the riveted position of the water port of the water nozzle is very likely to have a rigid collision with the riveted weld of the upper plate, which makes the riveted position of the water port of the water nozzle very likely to break and be damaged, thereby ultimately reducing the riveting effect of the water nozzle. Utility Model Content

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a riveted welding structure for a water nozzle of a liquid cooling plate that is resistant to knocking and firmly riveted.

[0011] The water nozzle riveted welding structure of the liquid cooling plate also includes an expansion cone;

[0012] The expansion cone is arranged on a side of the riveted weld away from the water nozzle; the cone head of the expansion cone extends to the inner cavity of the water nozzle through the water flow port of the water nozzle, and is arranged opposite to the knocking part; the ratio of the diameter of the inner ring of the annular riveted boss to the diameter of the outer ring of the annular riveted boss is 14:15, and the peripheral wall of the cone head of the expansion cone abuts against the annular riveted boss, so that the annular riveted boss is expanded and riveted to the riveted weld.

[0013] In one embodiment, the diameter of the inner ring of the annular riveting boss ranges from 13 mm to 15 mm; and / or,

[0014] The diameter of the outer ring of the annular riveting boss ranges from 14 mm to 16 mm.

[0015] In one of the embodiments, a peripheral wall of the water outlet of the water nozzle protrudes radially to form a stop plate, and the stop plate abuts and seals against the peripheral edge of the riveted weld.

[0016] In one of the embodiments, a buffer water retaining ring is sleeved outside the annular riveted boss, and two ends of the buffer water retaining ring are respectively abutted and sealed against the periphery of the riveted weld and the disk surface of the abutting disk.

[0017] In one of the embodiments, the water nozzle is provided with an external connection port at the striking portion, and the end surface of the external connection port is arc-shaped.

[0018] In one embodiment, the external port, the water port, the riveted weld and the cone head of the expansion cone are coaxially arranged.

[0019] In one embodiment, a first guide slope is provided on a side of the annular riveting boss near the riveting weld; and / or,

[0021] In one of the embodiments, a plurality of vertical abutment edges are provided at intervals on the peripheral wall of the cone head of the expansion cone, and each of the vertical abutment edges abuts against the inner annular wall of the annular riveted boss respectively; two adjacent vertical abutment edges are recessed inwardly and form a resistance-reducing gap with the inner annular wall of the annular riveted boss.

[0022] In one embodiment, each of the vertical abutments is divided into a guide sliding section and a support section, and the guide sliding section and the support section are arranged in sequence from the cone tip of the cone head to the cone seat of the cone head; each of the guide sliding sections is arranged at intervals around the cone tip of the cone head to form a pre-embedded structure; each of the support sections is arranged at intervals around the cone seat of the cone head to form an expansion structure.

[0025] 1) Compared with the prior art integrated hot and cold liquid cooling plates, in the riveted welding structure of the water nozzle of the liquid cooling plate disclosed in the present invention, by arranging the expansion cone on the side of the riveted weld away from the water nozzle, when the cone head of the expansion cone extends to the inner cavity of the water nozzle, the cone head of the expansion cone will be opposite to the knocking part. At the same time, because the surrounding wall of the cone head of the expansion cone abuts against the annular riveted boss, when the user applies a knocking force to the knocking part, the annular riveted boss is simultaneously subjected to the knocking force and the supporting force of the cone head of the expansion cone. The supporting force of the cone head of the expansion cone can offset part of the knocking force, so that the knocking force on the water nozzle remains moderately stable, thereby alleviating the situation where the water nozzle is damaged due to excessive knocking force.

At the same time, because the peripheral wall of the cone head of the expansion cone abuts against the annular riveted boss, the annular riveted boss will be more easily expanded and deformed outward during the knocking process, and ultimately the annular riveted boss can be more securely riveted to the riveted weld.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0037] like Figure 1 and Figure 2 As shown, a water nozzle riveted welding structure 10 of a liquid cooling plate of an embodiment includes a liquid cooling plate 100, a water nozzle 200 and a support cone 400; the liquid cooling plate 100 is used to carry batteries, and a riveted weld 110 is provided on the liquid cooling plate 100; an annular riveted boss 2210 is convexly provided on the end surface of a water outlet port 220 of the water nozzle 200, and a knocking portion 210 is provided at one end of the water nozzle 200 away from the annular riveted boss 2210, and the knocking portion 210 is used to withstand the knocking force; the water outlet port 220 of the water nozzle 200 is riveted to the riveted weld through the annular riveted boss 2210 Mouth 110; the expansion cone 400 is arranged on the side of the riveted weld 110 away from the faucet 200; the cone head 410 of the expansion cone 400 extends to the inner cavity 230 of the faucet 200 through the water flow port 220 of the faucet 200, and is arranged opposite to the knocking part 210; the ratio of the diameter of the inner ring of the annular riveted boss 2210 to the diameter of the outer ring of the annular riveted boss 2210 is 14:15, and the peripheral wall of the cone head 410 of the expansion cone 400 abuts against the annular riveted boss 2210, so that the annular riveted boss 2210 is expanded and riveted to the riveted weld 110.

[0038] It can be understood that compared with the prior art integrated hot and cold liquid cooling plate, in the water nozzle riveted welding structure 10 of the liquid cooling plate of the present embodiment, by setting the expansion cone 400 on the side of the riveted weld 110 away from the water nozzle 200, when the cone head 410 of the expansion cone 400 extends to the inner cavity 230 of the water nozzle 200, the cone head 410 of the expansion cone 400 will be opposite to the knocking part 210. At the same time, because the surrounding wall of the cone head 410 of the expansion cone 400 abuts against the annular riveted boss 2210, when the user applies a knocking force to the knocking part 210, the annular riveted boss 2210 is simultaneously subjected to the knocking force and the supporting force of the cone head 410 of the expansion cone 400. The supporting force of the cone head 410 of the expansion cone 400 can offset part of the knocking force, so that the knocking force on the water nozzle 200 remains moderately stable, thereby alleviating the situation where the water nozzle 200 is damaged due to excessive knocking force.

[0039] It can be understood that compared with the hot and cold integrated liquid cooling plate of the prior art, in the water nozzle riveting welding structure 10 of the liquid cooling plate of the present embodiment, because the ratio of the diameter of the inner ring of the annular riveting boss 2210 to the diameter of the outer ring of the annular riveting boss 2210 is 14:15, the annular riveting boss 2210 maintains an appropriate thickness, while reducing the rigidity of the annular riveting boss 2210, the flexibility of the annular riveting boss 2210 can be improved, so that the water nozzle 200 can be knocked during the annular riveting boss 2210. The riveting boss 2210 will be more easily riveted into the riveting weld 110, and will be less likely to have a rigid collision with the riveting weld 110, thereby reducing the possibility of damage to the faucet 200 caused by excessive striking force. At the same time, because the peripheral wall of the cone head 410 of the expansion cone 400 abuts against the annular riveting boss 2210, the annular riveting boss 2210 is also more likely to expand and deform outward during the striking process, ultimately allowing the annular riveting boss 2210 to rivet the riveting weld 110 more securely.

[0040] In one embodiment, the diameter of the inner ring of the annular riveted boss 2210 is in the range of 13mm to 15mm. It can be understood that by setting the diameter of the inner ring of the annular riveted boss 2210 in the range of 13mm to 15mm, it is possible to avoid the inner ring of the annular riveted boss 2210 being too small in diameter, which causes the liquid flow rate in the liquid cooling plate to be slow and weaken the heat dissipation effect, and at the same time, it is possible to avoid the inner ring of the annular riveted boss 2210 being too large in diameter, which causes the liquid flow rate in the liquid cooling plate to be too fast and difficult to fully exchange heat with the battery, resulting in uneven heat dissipation. Furthermore, the diameter of the outer ring of the annular riveted boss 2210 is in the range of 14mm to 16mm. It can be understood that by setting the diameter of the outer ring of the annular riveting boss 2210 within the range of 14 mm to 16 mm, the diameter of the outer ring of the annular riveting boss 2210 can be maintained within an appropriate range, so that the thickness between the inner ring of the annular riveting boss 2210 and the outer ring of the annular riveting boss 2210 is appropriate, while reducing the rigidity of the annular riveting boss 2210, the flexibility of the annular riveting boss 2210 can be improved, which is more conducive to the riveting cooperation between the annular riveting boss 2210 and the riveting weld 110.

[0041] In this embodiment, the diameter of the inner ring of the annular riveting boss 2210 is set to 14 mm, and the diameter of the outer ring of the annular riveting boss 2210 is set to 15 mm, so that the wall thickness of the annular riveting boss 2210 is 1 mm. It can be understood that because the wall thickness of the annular riveting boss 2210 is 1 mm, the annular riveting boss 2210 has stronger flexibility while reducing rigidity, which can avoid the direct rigid collision between the annular riveting boss 2210 and the riveting weld 110, making it easier to rivet in the riveting weld 110, and easier to be riveted to the outer shape by the expansion effect of the cone head 410 of the expansion cone 400.

[0042] like Figure 2 As shown, in one embodiment, a peripheral wall of the water outlet 220 of the faucet 200 protrudes radially to form a stop plate 2220 , and the stop plate 2220 abuts and seals against the peripheral edge of the riveted weld 110 . It can be understood that because the stopper 2220 is formed by the radial protrusion of the peripheral wall of the water port 220 of the faucet 200, the stopper 2220 will be close to and protrude from the outer annular wall of the annular riveted boss 2210. When the annular riveted boss 2210 is riveted in the riveted weld 110, if the user continues to knock on the knocking portion 210 of the faucet 200, the stopper 2220 can abut against the peripheral edge of the riveted weld 110 to buffer the knocking force applied to the faucet 200, which can not only prevent the annular riveted boss 2210 from passing through the riveted weld 110 and causing damage, but also enable the stopper 2220 to press and seal the peripheral edge of the riveted weld 110, thereby effectively reducing leakage of liquid in the liquid cooling plate.

[0043] Combination Figure 3 As shown, in another embodiment, a buffer water retaining ring 300 is further sleeved outside the annular riveted boss 2210, and the two ends of the buffer water retaining ring 300 are respectively abutted against the periphery of the riveted weld 110 and the disk surface of the abutment plate 2220 for sealing. It can be understood that by sleeved the buffer water retaining ring 300 outside the annular riveted boss 2210, when the abutment plate 2220 abuts against the periphery of the riveted weld 110, the buffer water retaining ring 300 will be pressed between the abutment plate 2220 and the liquid cooling plate 100, so that the two ends of the buffer water retaining ring 300 can respectively abut against the periphery of the sealed riveted weld 110 and the disk surface of the abutment plate 2220.

[0044] like Figure 1 and Figure 3 As shown, in one embodiment, the faucet 200 is provided with an external port 2110 at the knocking portion 210, and the end surface of the external port 2110 is arc-shaped. It can be understood that because the external port 2110 is provided at the knocking portion 210 of the faucet 200, the external port 2110 is connected to the water flow port 220 through the inner cavity 230 of the faucet 200, so that liquid can enter or flow out of the inner cavity 230 of the faucet 200 through the external port 2110. By setting the end surface of the external port 2110 to be arc-shaped, the arc-shaped structure has a better buffering effect during the knocking process, can resist a greater knocking force, and makes the faucet 200 less likely to be damaged during the knocking process.

[0045] Combination Figure 1As shown, in this embodiment, the external port 2110 , the water flow port 220 , the riveted weld 110 and the cone head 410 of the expansion cone 400 are coaxially arranged. It can be understood that by arranging the external port 2110, the water flow port 220, the riveted weld 110 and the cone head 410 of the expansion cone 400 on the same axis, the force transmission can be more direct and efficient. When the user knocks on the external port 2110 of the faucet 200, the knocking force can directly act on the riveted weld 110 through the water flow port 220 of the faucet 200. The annular riveted boss 2210 on the end face of the water flow port 220 can be directly riveted into the riveted weld 110 after being hit. The faucet 200 will not deflect during this process. The cone head 410 of the expansion cone 400 circumferentially expands the annular riveted boss 2210, so that the annular riveted boss 2210 can quickly rivet the riveted weld 110.

[0046] like Figure 4 As shown, in one embodiment, the table surface of the annular riveted boss 2210 is provided with a first guide sliding inclined surface 2211 on one side close to the riveted weld 110. It can be understood that the first guide sliding inclined surface 2211 is inclined downward from one end close to the water port 220 to one end close to the riveted weld 110. Before knocking, the water nozzle 200 is first aligned with the riveted weld 110 on the liquid cooling plate 100, and the first guide sliding inclined surface 2211 slides against the riveted weld 110. By knocking the knocking part 210, the user can make the annular riveted boss 2210 enter the riveted weld 110 more smoothly along the first guide sliding inclined surface 2211, and further avoid the direct rigid collision between the annular riveted boss 2210 and the riveted weld 110.

[0047] like Figure 4 As shown, in one embodiment, the surface of the annular riveted boss 2210 is provided with a second guide sliding inclined surface 2212 on one side close to the cone head 410 of the expansion cone 400, and the second guide sliding inclined surface 2212 slides against the peripheral wall of the cone head 410 of the expansion cone 400. It can be understood that the second guide sliding inclined surface 2212 is inclined upward from one end close to the cone head 410 of the expansion cone 400 to one end close to the water flow port 220 of the faucet 200. By making the second guide sliding inclined surface 2212 slide against the peripheral wall of the cone head 410 of the expansion cone 400, when the user knocks the faucet 200, the cone head 410 of the expansion cone 400 can move straight into the water flow port 220 along the second guide sliding inclined surface 2212, so that the cone head 410 of the expansion cone 400 can expand the annular riveted boss 2210 more stably and is less likely to deflect during the movement.

[0048] Combination Figure 1As shown, in one of the embodiments, a plurality of vertical abutment edges 4110 are provided at intervals on the peripheral wall of the cone head 410 of the expansion cone 400, and each vertical abutment edge 4110 abuts against the inner annular wall of the annular riveted boss 2210 respectively; two adjacent vertical abutment edges 4110 are recessed inwardly, and a resistance reduction gap 411d is formed between the inner annular wall of the annular riveted boss 2210. It can be understood that since the two adjacent vertical abutment edges 4110 are recessed inward, when the cone head 410 of the expansion cone 400 extends into the inner ring of the annular riveting boss 2210, each vertical abutment edge 4110 respectively abuts against the inner ring wall of the annular riveting boss 2210, and forms a resistance reduction gap 411d between the inner ring wall of the riveting boss, which can reduce the contact friction while expanding the inner ring wall of the riveting boss, thereby preventing the cone head 410 of the expansion cone 400 from sliding due to excessive friction.

[0049] Combination Figure 1 and Figure 3 As shown, in the present embodiment, each vertical abutment 4110 is evenly divided into a guide sliding section 411a and a support section 411c, and the guide sliding section 411a and the support section 411c are sequentially arranged from the cone tip of the cone head 410 to the cone seat of the cone head 410; each guide sliding section 411a is arranged at intervals around the cone tip of the cone head 410 to form a pre-embedded structure 4111; each support section 411c is arranged at intervals around the cone seat of the cone head 410 to form a support structure 4112. It can be understood that before knocking the faucet 200, the pre-embedded structure 4111 is first embedded in the inner cavity 230 of the faucet 200 from the water port 220 of the faucet 200, so that the inner ring wall of the annular riveted boss 2210 can slide and abut against the guide slide section 411a. When the user knocks the faucet 200, the annular riveted boss 2210 can slide to the expansion structure 4112 under the action of the guide slide section 411a, and the abutting section 411c at the expansion structure 4112 abuts and circumferentially expands the annular riveted boss 2210, so that the annular riveted boss 2210 can rivet the riveted weld 110 more securely.

[0050] like Figure 4 As shown, specifically, the guide slide section 411a and the support section 411c are recessed to form a transition arc 411b. It can be understood that by providing the transition arc 411b between the guide slide section 411a and the support section 411c, the transition of the annular riveted boss 2210 from the guide slide section 411a to the support section 411c can be smoother and more continuous, thereby making the expansion process of the annular riveted boss 2210 smoother. Among them, the central angle of the transition arc 411b is 15°, which is not limited here, and those skilled in the art can also replace it as needed.

[0051] In one embodiment, the taper of the cone head 410 of the expansion cone 400 is 0.93. It can be understood that by setting the taper of the cone head 410 of the expansion cone 400 to 0.93, the surrounding wall of the cone head 410 of the expansion cone 400 can maintain a suitable slope, which can not only prevent the cone head 410 of the expansion cone 400 from being too flat and difficult to expand and extend into the annular riveting boss 2210, but also prevent the cone head 410 of the expansion cone 400 from being too inclined and difficult to achieve the expansion effect. Of course, the taper of the cone head 410 of the expansion cone 400 can also be adjusted according to the inner diameter of the annular riveting boss 2210, which is not limited here, and those skilled in the art can make adjustments as needed.

[0052] Compared with the prior art, the present invention has at least the following advantages:

[0053] 1) Compared with the prior art integrated hot and cold liquid cooling plate, in the disclosed liquid cooling plate's water nozzle riveted welding structure 10, by arranging the expansion cone 400 on the side of the riveted weld 110 away from the water nozzle 200, when the cone head 410 of the expansion cone 400 extends to the inner cavity 230 of the water nozzle 200, the cone head 410 of the expansion cone 400 will be opposite to the knocking portion 210. At the same time, because the surrounding wall of the cone head 410 of the expansion cone 400 abuts against the annular riveted boss 2210, when the user applies a knocking force to the knocking portion 210, the annular riveted boss 2210 is simultaneously subjected to the knocking force and the supporting force of the cone head 410 of the expansion cone 400. The supporting force of the cone head 410 of the expansion cone 400 can offset part of the knocking force, so that the knocking force on the water nozzle 200 remains moderately stable, thereby alleviating the situation where the water nozzle 200 is damaged due to excessive knocking force.

[0054] 2) Compared with the hot and cold integrated liquid cooling plate of the prior art, in the water nozzle riveting welding structure 10 of the disclosed liquid cooling plate, because the ratio of the diameter of the inner ring of the annular riveting boss 2210 to the diameter of the outer ring of the annular riveting boss 2210 is 14:15, the annular riveting boss 2210 maintains an appropriate thickness, while reducing the rigidity of the annular riveting boss 2210, the flexibility of the annular riveting boss 2210 can be improved, so that the annular riveting boss 2210 can be more flexible during the knocking process of the water nozzle 200. The platform 2210 will be more easily riveted into the riveted weld 110, and will be less likely to have a rigid collision with the riveted weld 110, thereby reducing the damage of the faucet 200 caused by excessive knocking force. At the same time, because the peripheral wall of the cone head 410 of the expansion cone 400 abuts against the annular riveted boss 2210, the annular riveted boss 2210 will be more easily expanded and deformed outward during the knocking process, and finally the annular riveted boss 2210 can be more securely riveted to the riveted weld 110.

[0055] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
