[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Figure 1 is a schematic structural diagram of a preferred embodiment of the ejection structure of the potting box assembly and the heat dissipation assembly of the electronic device of the present utility model. Figure 2 is a cross-sectional view of a preferred embodiment of the ejection structure of the potting box assembly and the heat dissipation assembly of the electronic device of the present utility model. Figure 3 is an assembly schematic diagram of the potting box assembly and the liquid cooling plate.

[0021] The following will first be combined with Figure 1-2 The ejection structure of the potting box assembly of the present utility model is described as follows. As Figure 1 shown, the ejection structure of the potting box assembly of the present utility model includes: a fixing portion 11 provided on one side of the potting box assembly 10, a potting box threaded hole 12 penetrating through the fixing portion 11, a stopping groove 21 provided on the liquid cooling plate 20 opposite to the potting box threaded hole 12, and an ejection screw 30. As Figure 2 shown, the diameter X of the stopping groove 21 is greater than the diameter of the ejection screw 30. The thread specification of the ejection screw 30 matches the thread of the potting box threaded hole 12. The thread length of the ejection screw 30 is greater than the sum of the length of the fixing portion 11 and the depth of the stopping groove 21, so that the ejection screw 30 ejects the potting box assembly 10 when locked through the potting box threaded hole 12 and the stopping groove 21. AsFigure 1 As shown, the anti-advancing groove 21 is a groove provided on the surface of the liquid cooling plate 20 facing the glue filling box threaded hole 12.

[0022] Figure 3 It is an assembly schematic diagram of the glue filling box assembly and the liquid cooling plate. As Figure 3 shown, the glue filling box assembly 10 is in close contact with the liquid cooling plate 20, and disassembly is very difficult. As Figure 2 shown, after applying silicone grease to fill the gap and lock the contact surface between the glue filling box assembly 10 and the liquid cooling plate 20, when disassembly is required, since the diameter X of the anti-advancing groove 21 is greater than the diameter of the ejector screw 30, the ejector screw 30 can be locked from the glue filling box threaded hole 12 to the anti-advancing groove 21. And because the thread length of the ejector screw 30 is greater than the sum of the length of the fixing part 11 and the depth of the anti-advancing groove 21, when the ejector screw 30 is locked from the glue filling box threaded hole 12 to the anti-advancing groove 21, the deformation principle of the liquid cooling plate 20 can be utilized to lift the glue filling box assembly 10, so as to conveniently disassemble the glue filling box assembly 10 and the liquid cooling plate 20. In a preferred embodiment of the present invention, the diameter X of the anti-advancing groove 21 and the diameter of the ejector screw 30 can adopt any suitable dimensions, as long as the former is greater than the latter. In a preferred embodiment of the present invention, the glue filling box threaded hole 12 is an M5 threaded hole, that is, an M5 threaded hole matching the M5 thread size is formed on the glue filling box assembly 10, its nominal diameter is 5 mm, the outer diameter is also 5 mm, the pitch is 0.8 mm, and the bottom hole diameter is 4.2 mm.

[0023] Furthermore, as Figure 1 shown, the fixing part 11 includes a fixing step 1 and protective side walls 2 provided on both sides of the fixing step 1. The glue filling box threaded hole 12 penetrates through the fixing step 1. As Figure 2 shown, a liquid cooling plate threaded hole 22 for locking the glue filling box assembly 10 to the liquid cooling plate 20 by a fixing screw is provided at the lower part of the anti-advancing groove 21. As Figure 2 shown, the diameter of the liquid cooling plate threaded hole 22 is smaller than the diameter of the ejector screw 30, and the diameter of the liquid cooling plate threaded hole 22 is smaller than the diameter of the glue filling box threaded hole 12; the thread length L of the ejector screw 30 is greater than the sum of the height a of the fixing step 1 and the depth b of the anti-advancing groove 21. In a preferred embodiment of the present invention, the liquid cooling plate threaded hole 22 is an M4 threaded hole, that is, an M4 threaded hole matching the M4 thread size is formed on the liquid cooling plate, its nominal diameter is 4 mm, the outer diameter is also 4 mm, the pitch is 0.7 mm, and the bottom hole diameter is 3.3 mm. Of course, in a further preferred embodiment of the present invention, the diameter of the anti-advancing groove 21 is preferably greater than the diameter of the liquid cooling plate threaded hole 22.

[0024] During normal assembly, since the diameter of the threaded hole 12 of the potting box is larger than that of the threaded hole 22 of the liquid cooling plate, it can be ensured that the fixing screw (not shown) for locking the liquid cooling plate can pass through the threaded hole of the potting box, thereby fixing the potting box assembly and the liquid cooling plate. When disassembly is required, first remove the fixing screw for locking the liquid cooling plate, and then perform the ejection disassembly operation. Since a groove is provided as the stop groove 21 for the ejection screw 30 on the surface of the liquid cooling plate 20 facing the threaded hole 12 of the potting box, the ejection screw 30 can be locked from the threaded hole 12 of the potting box to the stop groove 21 of the liquid cooling plate 20. Since the diameter X of the stop groove > the diameter of the ejection screw; the thread length L of the ejection screw > the depth a of the stop groove + the height b of the fixed step, when the ejection screw 30 is locked to the stop groove 21 of the liquid cooling plate 20, the potting box assembly 10 can be lifted just by tightening the ejection screw 30.

[0025] In Figure 1 In the preferred embodiment shown, two ejection screws 30 are provided. Correspondingly, a first fixing portion 11 and a second fixing portion 11 are respectively provided on the first side and the second side of the potting box assembly 10, and a first stop groove 21 and a second stop groove 21 are respectively provided at positions of the liquid cooling plate 20 facing the first fixing portion 11 and the second fixing portion 11; the first ejection screw 30 and the second ejection screw 30 respectively eject the potting box assembly 10 when locked through the threaded hole 12 of the potting box in the first fixing portion 11 and the second fixing portion 11 and the first stop groove 21 and the second stop groove 21. In other preferred embodiments of the present invention, more ejection screws and their corresponding fixing portions and stop grooves can also be provided. Here, no specific limitation is imposed on their specific numbers.

[0026] Further as Figure 1 shown, the potting box assembly 10 includes a cuboid potting box 13, a PCB board 14 and electronic components accommodated in the cuboid potting box 13; the first fixing portion 11 and the second fixing portion 11 are respectively provided on the first side face and the second side face of the cuboid potting box 13 that face each other, and the bottom surface of the cuboid potting box 13 is attached to the liquid cooling plate 20. In a further preferred embodiment of the present invention, the shape of the potting box can be designed according to the PCB board and electronic components that need to be actually accommodated.

[0027] Implementing the ejection structure of the potting box assembly of the present invention, through a clever structural design, simply using an ejection screw can easily complete the disassembly of the potting box assembly and the liquid cooling plate, and the operation is simple and it is not easy to damage the potting box assembly and the liquid cooling plate.

[0028] Next, first in combination with Figure 1-2 the electronic device heat dissipation assembly of the present invention is described as follows.

A stop groove 21 is provided at a position on the liquid cooling plate 20 corresponding to the potting box threaded hole 12. The diameter X of the stop groove 21 is greater than the diameter of the ejector screw 30. The thread length of the ejector screw 30 is greater than the sum of the length of the fixing part 11 and the depth of the stop groove 21, so that when the ejector screws 30 are locked through the potting box threaded holes 12 and the stop grooves 21 respectively, the potting box component 10 is ejected.

[0029] In a further preferred embodiment of the present invention, the fixing part 11 includes a fixing step 1 and protective side walls 2 provided on both sides of the fixing step 1. The potting box threaded hole 12 is penetrated in the fixing step 1. The thread length of the ejector screw 30 is greater than the sum of the height of the fixing step 1 and the depth of the stop groove 21.

[0030] In a further preferred embodiment of the present invention, a liquid cooling plate threaded hole for locking the potting box component 10 to the liquid cooling plate 20 by a fixing screw is provided at the lower part of the stop groove 21. The diameter of the liquid cooling plate threaded hole is smaller than the diameter of the ejector screw 30, and the diameter of the liquid cooling plate threaded hole is smaller than the diameter of the potting box threaded hole 12.
