Description

Technical Field

[0001] The utility model relates to the technical field of water cooling plates, in particular to a water nozzle sealing device for a domain-controlled water cooling plate. Background Art

[0002] In the production process of domain-controlled water-cooled plates, magnetic grinding is widely used as an effective surface finishing method in processes such as die-casting capes and CNC post-burr removal. During the magnetic grinding process, magnetic abrasives are arranged along a specific magnetic field direction to form an "abrasive brush", which grinds the workpiece surface by rotating and moving. Commonly used magnetic abrasives are made of steel needles with a diameter of 1.0 mm and a length of 15 mm. However, during the magnetic grinding process, the magnetic grinding fluid and steel needles are likely to enter the flow channel of the water-cooled plate, affecting the heat dissipation effect.

[0003] At present, in order to prevent magnetic grinding fluid and steel needles from entering the water-cooling plate flow channel, silicone plugs and other methods are usually used to seal the water nozzles. However, traditional sealing materials such as silicone plugs are not only prone to loosening during use, but also have a high probability of falling off, causing impurities such as grinding fluid or steel needles to enter the water-cooling plate along the flow channel, reducing the cooling efficiency of the product. Under long-term use conditions, pollutants may corrode the product, further deteriorate the cooling effect, cause the vehicle domain controller temperature to rise, and even affect the service life of the server, increasing the risk of vehicle use.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1

[0037] In order to solve the technical problem that the sealing structure of the traditional domain-controlled water-cooling plate nozzle is easy to loosen, and impurities such as grinding fluid or steel needles will enter the water-cooling plate along the flow channel, reducing the cooling efficiency of the product, please refer to Figure 1-Figure 3The utility model provides a domain-controlled water-cooling plate faucet sealing device, which can install a sealing cap 2 on the faucet to seal it, preventing foreign matter such as grinding fluid and steel needles from entering the flow channel through the faucet. The sealing device is provided with an integrally formed clamp 1 and a sealing cap 2 installed on the outside thereof. The clamp 1 includes two half clamps 101 that can be bent relative to each other. An adaptation groove 102 is provided between the two half clamps 101. The adaptation groove 102 can provide bending space for the two half clamps 101, which is convenient for unfolding the two half clamps 101 and wrapping them around the outside of the faucet. A plurality of evenly distributed first springs 3 are fixedly installed inside the adaptation groove 102. The two half clamps 101 can be tightly clamped on the faucet by the elastic force of the first spring 3, and a sub-buckle 103 is provided at the bottom of one of the half clamps 101, and a female buckle 104 adapted to the sub-buckle 103 is provided at the bottom of the other half clamp 101. After the half clamp 101 is installed, the sub-buckle 103 can be clamped in the female buckle 104 to achieve preliminary fixation of the two half clamps 101 and combine to form the clamp 1. Figure 1 A sealing gasket is also provided between the clamp 1 and the sealing cap 2. The sealing gasket is fixedly installed on the inner wall of the sealing cap 2. The sealing cap 2 can then be threadedly installed on the clamp 1. At this time, the sealing cap 2 and the sealing gasket can seal the water spout to achieve sealing of the water spout.

[0038] Example 2

[0039] The sealing effect of sealing the faucet with a sealing gasket alone is limited. In particular, the threads between the sealing cap 2 and the clamp 1 may become loose, which may easily lead to a gap between the faucet and the sealing gasket. Grinding fluid may still enter the faucet and cause contamination of the flow channel. To further optimize the sealing effect of the equipment on the faucet, please refer to Figure 4-Figure 7A sealing mechanism 4 is provided inside the sealing cap 2 for sealing it from the inside of the water nozzle, so that even if the sealing cap 2 and the clamp 1 become loose, the sealing mechanism 4 can block the liquid source from the inside of the water nozzle, wherein a spacer ring 41 is fixedly installed on the inner wall of the sealing cap 2, a support 42 is fixedly installed inside the spacer ring 41, and a ring-shaped sealing airbag 43 is installed on one side of the support 42. A pull rod 44 coaxially arranged with the sealing airbag 43 is slidably connected to the inside of the sealing cap 2, and one end of the pull rod 44 passes through the support 42 and the sealing airbag 43 in turn, and is provided with a blocking block 47 to prevent foreign matter such as grinding liquid or steel needles from entering the domain control water cooling plate from the water nozzle. The blocking block 47 is conical in shape, and its diameter is from the diameter close to the sealing airbag 43. The sealing airbag 43 is pressed against the faucet 1 and the sealing block 47 is pressed against the faucet 1. The sealing airbag 43 is pressed against the faucet 1 and the sealing block 47 is pressed against the faucet 1.

[0040] After pulling the pull rod 44 to drive the sealing block 47 and the sealing air bag 43 to seal the faucet, the pull rod 44 needs to be fixed. Therefore, a limiter 45 is provided on the outside of the sealing cap 2 to fix the pull rod 44. The limiter 45 includes a steering plate 451 fixedly installed at the end of the pull rod 44 and an extension rod 452 fixedly installed at the bottom of the sealing cap 2. One side of the extension rod 452 is provided with a plurality of limit grooves 453 for inserting the steering plate 451. Pull the pull rod 44 to a certain position, and then rotate the steering plate 451 so that the steering plate 451 is inserted into the limit groove 453. The limit groove 453 can limit the steering plate 451 in the front and rear directions to prevent the pull rod 44 from sliding, thereby ensuring that the sealing air bag 43 can be in close contact with the inner wall of the faucet to prevent the faucet from being contaminated.

[0041] Example 3

[0042] The two clamping blocks 53 are symmetrically arranged, and the two sides of the sealing cap 2 are slidably connected to the bending rod 56. The top and bottom of the bending rod 56 are provided with a clamping groove 57 adapted to the clamping block 53. After the bending rod 56 slides into the support rod 51, the clamping block 53 can be engaged in the clamping groove 57 by the elastic force of the second spring 52, realizing the connection between the support rod 51 and the bending rod 56, thereby realizing the secondary connection between the clamping block 1 and the sealing cap 2, preventing the sealing cap 2 from falling off the clamping block 1 when the thread is loose.

[0043] When the bending rod 56 slides into the support rod 51, the two blocks 53 need to be squeezed apart. Therefore, a pointed head 58 is provided at the end of the bending rod 56. The pointed head 58 is provided between the two blocks 53, and the slope of the pointed head 58 is set to 15°-35°. When the pointed head 58 slides toward the block 53, the two blocks 53 can be squeezed apart. At this time, the second spring 52 is deformed until the pointed head 58 moves to the block 53 to correspond to the slot 57. The block 53 can enter the slot 57 through the elastic force of the second spring 52, thereby locking the bending rod 56.

[0044] After the sealing cap 2 is installed, it is necessary to first rotate the steering plate 451 to fix the steering plate 451, and then slide the bending rod 56 to fix the bending rod 56. The two operation steps are relatively troublesome. In order to solve this technical problem, the above two operation steps can be simplified into one operation step. A transmission member 46 is provided between the pull rod 44 and the anti-slip mechanism 5. The transmission member 46 includes a gear 461 slidably sleeved on the outside of the pull rod 44. The gear 461 is rotatably installed in the center position of the outer wall of the sealing cap 2. The outer wall of the sealing cap 2 is also slidably installed with two racks meshing with the gear 461. 462, the two racks 462 are respectively arranged on the upper and lower sides of the gear 461, and the two bending rods 56 are respectively fixedly installed on the ends of the two racks 462. When the steering plate 451 is rotated, the pull rod 44 and the gear 461 on the pull rod 44 can be driven to rotate. The rotation of the gear 461 can drive the rack 462 to slide, and the rack 462 pushes the bending rod 56 to slide, so that the steering plate 451 is rotated and fixed, and the bending rod 56 is sent into the support rod 51 to lock the bending rod 56. On the one hand, it ensures the sealing effect of the water nozzle, and on the other hand, it ensures the stability of the connection between the clamp 1 and the sealing cap 2.

[0045] In order to facilitate the unlocking of the pull rod 44, that is, to facilitate the disassembly and maintenance of the sealing cap 2, a third spring 463 is fixedly installed on the end of the rack 462 facing away from the bending rod 56, and a fixing plate 464 is fixedly installed on the end of the third spring 463. The fixing plate 464 is fixedly installed on the sealing cap 2. When the rack 462 slides and drives the bending rod 56 to be locked, the third spring 463 is in a deformed state. When the locking state of the bending rod 56 is released, the bending rod 56 and the rack 462 can be reset by the elastic force of the third spring 463, and at the same time drive the gear 461 to reverse, so that the steering plate 451 is moved out of the extension rod 452. There is no need to manually slide the rack 462, saving the operating steps of the disassembly process.

[0046] Reference Figure 8 As shown, the side surfaces of the two clamping blocks 53 extend to the outside of the support rod 51 and are hinged with a connecting rod 54. A connecting seat 55 is installed between the two connecting rods 54, and the ends of the two connecting rods 54 are rotatably installed on the connecting seat 55. Pressing the connecting seat 55 can drive the two connecting rods 54 to rotate. The rotation of the connecting rod 54 can push the two clamping blocks 53 apart, prompting the bending rod 56 to reset. Therefore, when removing the sealing cap 2, it is only necessary to press the two connecting seats 55.

[0047] Example 4

[0048] Since the sealing airbag 43 plays a major sealing role in the sealing cap 2, if the sealing airbag 43 is damaged and leaks, the sealing airbag 43 will not be able to fit tightly with the faucet and the blocking block 47, affecting the sealing effect of the equipment. In order to solve this technical problem, the interior of the sealing airbag 43 is provided with a circular main air cavity 431 and an annular auxiliary air cavity 432, and the interior of the auxiliary air cavity 432 is provided with at least five dividing strips 433 connected to the outer wall of the main air cavity 431. The dividing strips 433 are arranged at an angle, and the main air cavity 431 can provide support for the sealing airbag 43 as a whole. The main air cavity 431 is located at the center of the sealing airbag 43 and is not easily damaged, thereby ensuring the overall structure of the sealing airbag 43. The dividing strip 433 can cooperate with the main air cavity 431 to provide support for the sealing airbag 43 as a whole, and on the other hand, the internal space of the auxiliary air cavity 432 can be divided into multiple small chambers. When one of the small chambers is damaged, the other small chambers can still cooperate with the main air cavity 431 to support the sealing airbag 43 to seal the faucet, which can greatly reduce the possibility of the flow channel being contaminated due to damage to the sealing airbag 43.

[0049] If the sealing airbag 43 is damaged, it is necessary to replace the sealing airbag 43 in time. Therefore, the blocking block 47 is movably sleeved on the outside of the pull rod 44, and the outside of the pull rod 44 is also fixedly sleeved with an abutment piece 48 that fits with one side of the blocking block 47, and the end of the pull rod 44 is threadedly installed with an anti-drop cap 49 that fits with the other side of the blocking block 47. The anti-drop cap 49 and the abutment piece 48 can fix the blocking block 47 on the pull rod 44. When the sealing airbag 43 needs to be replaced, the anti-drop cap 49 is rotated to remove the blocking block 47 first, and then the sealing airbag 43 can be removed from the support 42. The connection method of the sealing airbag 43 and the support 42 can adopt other more convenient detachable connections such as threaded connection or clamping, which is convenient for replacing the sealing airbag 43.
