Description

Technical Field

[0001] This invention relates to the field of cooling plate technology, and in particular to a built-in tubular flow channel plate and its assembly method. Background Technology

[0002] With the development of electronic technology towards integration and high power, higher demands are being placed on cooling and heat dissipation technologies. Traditional natural cooling and forced air cooling can no longer meet the heat dissipation requirements of high-power devices, and liquid cooling technology has become one of the most effective heat dissipation methods. Currently, heat dissipation of the chassis can be achieved through a liquid cooling carrier structure. The flow channel plate, as the main heat dissipation component of the liquid cooling carrier structure, uses a liquid pump to circulate the coolant within the flow channels of the flow channel plate, carrying away the heat generated by the chassis. Currently, there are two main types of flow channel plates: integrated metal-based flow channel plates and internal tubular flow channel plates.

[0003] Existing built-in tubular flow channel plates are machined and tin-plated brazed (or glued) for the tubing. The built-in tubing is generally made of copper alloy and is formed by tin-plated brazing or glue bonding, which solves the problem of galvanic corrosion to some extent. However, the main problems include: the fit between the built-in tubing and the corresponding tubing groove is not tight, resulting in insufficient heat conduction; the thermal resistance of the liquid cooling carrier structure is relatively large, which cannot meet the heat dissipation requirements of high-power devices; the quality of brazing and gluing is unstable, and the flux and adhesive themselves have high thermal resistance, which cannot meet the heat dissipation requirements of high-power devices.

[0004] Furthermore, both of the above liquid cooling methods have the limitation of not being able to centrally cool heat-generating components in specific areas.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the welding process of existing built-in tubular flow channel plates is complicated, the fit between the tube and the channel is not tight, and the thermal resistance of the brazing or adhesive materials is high, which leads to the heat dissipation not meeting the heat dissipation requirements of high-power devices.

[0055] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] Example 1:

[0057] Embodiment 1 of the present invention provides a built-in tubular flow channel plate, such as Figures 1-4 As shown, it includes: a first conduit 1, a second conduit 2, a first cover plate 3, a second cover plate 4, a first substrate 5, and a second substrate 6. The first conduit 1 and the second conduit 2 are configured as follows: Figure 2 and Figure 4 The S-shaped pipe shown can be made of highly corrosion-resistant materials such as stainless steel and titanium alloy, and its cross-section can be circular, rectangular, or other structural forms.

[0058] The first substrate 5 and the second substrate 6 are respectively disposed on opposite sides of the liquid cooling carrier structure. The first pipe 1 is disposed on the first substrate 5. The first cover plate 3 encloses the area on the first substrate 5 where the first pipe 1 is placed. The first cover plate 3 and the first substrate 5 are fixedly connected. The first pipe 1 is interference-fitted with the first cover plate 3 and the first substrate 5 respectively to minimize the gap between the three and reduce thermal resistance.

[0059] The second conduit 2 is disposed on the second substrate 6, and the second cover plate 4 encloses the area on the second substrate 6 where the second conduit 2 is placed. The second cover plate 4 and the second substrate 6 are fixedly connected, and the second conduit 2 is interference-fitted with the second cover plate 4 and the second substrate 6 respectively, so as to minimize the gap between the three and reduce the thermal resistance.

[0060] To allow coolant to flow between the first pipe 1 and the second pipe 2, refer to... Figure 2 As shown, a connecting pipe 20 is provided between the first pipe 1 and the second pipe 2 to allow coolant to flow in the first pipe 1 and the second pipe 2.

[0061] In existing built-in tubular flow channel structures, brazing and adhesive bonding are mostly used to connect the first pipe 1 and the second pipe 2 to other components. However, brazing and adhesive bonding have poor stability for metal pipes, and the flux and adhesive themselves have high thermal resistance, which cannot meet the heat dissipation requirements of high-power devices. Based on this, refer to... Figure 1 As shown, the built-in tubular flow channel plate also includes a transition block assembly 7, which is disposed at the openings of the first pipe 1, the second pipe 2, and the connecting pipe 20. Each transition block in the transition block assembly 7 is provided with a hole system, including holes matching the diameter of the first pipe 1 and the second pipe 2, coolant flow channel turning holes, and connection and fastening mounting holes for the transition block. The hole system can be formed by machining.

[0062] In one embodiment, the first cover plate 3 and the second cover plate 4 can also be S-shaped. Figure 1 and Figure 3 The groove block 31 shown is disposed between the gap of the first cover plate 3 and the second cover plate 4 in the S-shape. The groove block 31 is disposed in the weight reduction groove. When the weight of the liquid cooling carrier structure is too large, the groove block 31 can be removed to reduce the weight of the liquid cooling carrier structure.

[0063] This invention achieves a tight fit between the pipes, substrates, and covers by press-fitting an interference fit between the first pipe 1, the first substrate 5, and the first cover plate 3, and between the second pipe 2, the second substrate 6, and the second cover plate 4. Furthermore, the first cover plate 3 is welded to the first substrate 5, and the second cover plate 4 is welded to the second substrate 6. This ensures a tight fit between the pipes, substrates, and covers, effectively preventing gaps and reducing thermal resistance, thereby achieving efficient heat dissipation. Moreover, the materials and welding methods used for welding the first pipe 1 and the second pipe 2 to the adapter block assembly 7 do not affect the heat dissipation performance of the flow channel plate.

[0064] In order to ensure that the first conduit 1 can be installed with as little clearance as possible with the first substrate 5, such as Figure 5 As shown, a first receiving groove 50 is provided on the first substrate 5, and the edge of the first cover plate 3 is placed in the first receiving groove 50, with the edge of the first cover plate 3 and the bottom surface of the first receiving groove 50 being press-fitted. A first arc-shaped groove 51 is provided at the bottom of the first receiving groove 50, and the first arc-shaped groove 51 is used to place the first pipe 1. In practical applications, when the first pipe 1 is placed in the first arc-shaped groove 51 and the first cover plate 3 is aligned with the first receiving groove 50, a hydraulic press is used to press the first cover plate 3 into the first receiving groove 50. Due to the limited thickness of the first substrate 5, the depth of the first arc-shaped groove 51 cannot completely accommodate the first pipe 1, and a portion of the first pipe 1 will protrude from the first arc-shaped groove 51. Furthermore, considering the tightness of the fit between the first pipe 1 and the first cover plate 3, such as... Figure 6 As shown, a second arc-shaped groove 30 is provided on the side of the first cover plate 3 that abuts against the first receiving groove 50. The second arc-shaped groove 30 is coupled to the portion of the first pipeline 1 that protrudes from the bottom of the first receiving groove 50. That is, the first pipeline 1 is interference-fitted with the first arc-shaped groove 51 and the second arc-shaped groove 30 respectively.

[0065] Similar to the first conduit 1, the first substrate 5, and the first cover plate 3 described above, such as... Figure 7As shown, a second receiving groove 60 is provided on the second substrate 6, and the edge of the second cover plate 4 is placed inside the second receiving groove 60. The edge of the second cover plate 4 is press-fitted with the bottom surface of the second receiving groove 60. A third arc-shaped groove 61 is provided at the bottom of the second receiving groove 60, and the third arc-shaped groove 61 is used to place the second pipe 2. A fourth arc-shaped groove 40 is provided on the side of the second cover plate 4 that abuts against the second receiving groove 60. The fourth arc-shaped groove 40 is coupled with the portion of the second pipe 2 that protrudes from the bottom of the second receiving groove 60. The second pipe 2 is press-fitted with both the third arc-shaped groove 61 and the fourth arc-shaped groove 40. Its structural design purpose is the same as that of the first pipe 1, the first substrate 5, and the first cover plate 3, and will not be described again here.

[0066] The first arc groove 51, the second arc groove 30, the third arc groove 61 and the fourth arc groove 40 mentioned in the above structure are formed by cutting.

[0067] To facilitate connections between pipes and avoid the instability of joint quality that can occur with welding or adhesive bonding, such as Figure 9 As shown, the adapter block assembly 7 includes a first adapter block 70, a second adapter block 71, a third adapter block 72, and a fourth adapter block 73. The first adapter block 70 is fixedly connected to one end of the first pipe 1, the second adapter block 71 is fixedly connected to the other end of the first pipe 1, the third adapter block 72 is fixedly connected to one end of the second pipe 2, and the fourth adapter block 73 is fixedly connected to the other end of the second pipe 2. Both ends of the connecting pipe 20 are fixedly connected to the second adapter block 71 and the fourth adapter block 73, respectively. Each of the first adapter block 70, the second adapter block 71, the third adapter block 72, and the fourth adapter block 73 has a perforation system for connecting to the first pipe 1, the second pipe 2, and the connecting pipe 20, allowing coolant to flow within these pipes.

[0068] In one embodiment, see Figure 9 As shown, the connecting pipe 20 is a straight pipe, which is disposed between the second adapter block 71 and the fourth adapter block 73. When the connecting pipe 20 is a straight pipe, its function is to connect the first pipe 1 and the second pipe 2. A cover plate is provided on the outside of the connecting pipe 20 for shielding.

[0069] In practical applications, during operation, certain electronic components inside the chassis 10 generate significant heat. Two-sided heat dissipation is insufficient to meet the cooling needs of these components. To achieve better cooling of the chassis 10, the cooling pipes need to cover a wider area of ​​the chassis 10. Figure 10As shown, a third pipe 11 is also provided between the first pipe 1 and the second pipe 2. The third pipe 11 is S-shaped. A first set of solenoid valves is provided at both ends of the connecting pipe 20, which is used to open and close both ends of the connecting pipe 20. A second set of solenoid valves is provided at both ends of the third pipe 11, which is also used to open and close both ends of the third pipe 11. The first set of solenoid valves includes two solenoid valves, one of which is located in the second adapter block 71 and the other in the fourth adapter block 73. Similarly, the second set of solenoid valves includes two solenoid valves, one of which is located in the second adapter block 71 and the other in the fourth adapter block 73.

[0070] In actual operation scenarios, if cooling of three sides of the chassis 10 is required, the solenoid valves at both ends of the connecting pipe 20 are closed, and the solenoid valves at both ends of the third pipe 11 are open, allowing coolant to flow from the first pipe 1 through the third pipe 11 to the second pipe 2, thereby achieving cooling of three sides of the chassis 10. If cooling of the side containing the third pipe 11 is not required, and cooling of the side containing the first pipe 1 and the second pipe 2 is concentrated, the solenoid valves at both ends of the third pipe 11 are closed, and the solenoid valves at both ends of the connecting pipe 20 are opened, allowing coolant to flow from the first pipe 1 through the connecting pipe 20 to the second pipe 2. The third pipe 11 is designed as an S-shaped pipe, so that it, along with the first pipe 1 and the second pipe 2, covers the three-sided area of ​​the liquid cooling carrier structure, thereby achieving a wider coverage area and better cooling effect. Similarly to the first pipe 1 and the second pipe 2, a cover plate is also provided on the outside of the connecting pipe 20 of the S-shaped pipe for sealing, and a base plate is provided for mounting.

[0071] See Figure 9 As shown, the built-in tubular flow channel plate is provided with an inlet pipe 8 and an outlet pipe 9. The adapter block assembly 7 further includes a fifth adapter block 74 and a sixth adapter block 75. One end of the inlet pipe 8 is fixedly connected to the fifth adapter block 74, and the other end of the inlet pipe 8 is fixedly connected to the first adapter block 70. One end of the outlet pipe 9 is fixedly connected to the sixth adapter block 75, and the other end of the outlet pipe 9 is fixedly connected to the third adapter block 72. A liquid supply pump (not shown in the figure) is externally connected to the inlet pipe 8 and is connected to the fifth adapter block 74. A drain pump (not shown in the figure) is externally connected to the outlet pipe 9 and is connected to the sixth adapter block 75.

[0072] In the above-described scheme, the first adapter block 70, the second adapter block 71, the third adapter block 72, the fourth adapter block 73, the fifth adapter block 74, and the sixth adapter block 75 are all designed with fixing holes for fixation, such as... Figure 11 The dashed box shows the components used to secure the various adapter blocks. Figure 11Only the fixing holes for the fifth adapter block 74 and the sixth adapter block 75 are shown in the image; the fixing holes for the first adapter block 70, the second adapter block 71, the third adapter block 72, and the fourth adapter block 73 are not shown. Figure 11 The fixing holes shown are all the same shape and are located at the bottom of the first adapter block 70, the second adapter block 71, the third adapter block 72, and the fourth adapter block 73 (taking the orientation shown in the figure as an example). The connecting pipe 20 of the first pipe 1, the second pipe 2, and the S-shaped pipe is formed by bending with a mold.

[0073] Based on the above solutions, embodiments of the present invention also provide an assembly method for an internal tubular flow channel plate, applicable to the internal tubular flow channel plate described in the above solutions, such as... Figure 12 As shown, it includes:

[0074] In step S1, the first pipeline 1 and the adapter block assembly 7 are assembled and placed inside the first substrate 5.

[0075] In step S2, the first cover plate 3 is placed over the first pipeline 1, and the first cover plate 3 is pressed into the first substrate 5 using a hydraulic press. The first cover plate 3 and the first substrate 5 are then welded and fixed together.

[0076] In step S3, the connecting pipe 20 is placed in the corresponding side plate of the liquid cooling carrier structure, the connecting pipe 20 is connected to the first pipeline 1 through the adapter block assembly 7, the side plate where the connecting pipe 20 is located is assembled with the first substrate 5, and the area where the connecting pipe 20 is located is sealed.

[0077] In step S4, the second conduit 2 and the adapter block assembly 7 are assembled and placed inside the second substrate 6.

[0078] The adapter block assembly 7 is sealed with O-rings between itself and the first pipeline 1, the second pipeline 2, and the connecting pipe 20.

[0079] In step S5, the second cover plate 4 is placed over the second pipeline 2, and the second cover plate 4 is pressed into the second substrate 6 using a hydraulic press. The second cover plate 4 and the second substrate 6 are then welded and fixed together.

[0080] In step S6, the second substrate 6 is fixed to the outside of the liquid cooling carrier structure, and the side plate of the liquid cooling carrier structure is sealed.

[0081] Compared with the prior art, the built-in tubular flow channel plate and assembly method provided in this embodiment have the following advantages: First, by incorporating high corrosion-resistant materials such as stainless steel and titanium alloy for the first pipe 1, second pipe 2, and connecting pipe 20, these components are cleaned before assembly. The cleaning operation is simple, with no dead corners, effectively solving problems such as uneven surface protection and pipe corrosion and leakage caused by potential differences between dissimilar metals in the welded integrated flow channel plate. Second, the pipes and substrate in this embodiment are mechanically pressed together, resulting in a simple process. The tubular flow channel is not affected by welding strength, eliminating the risk of pipe leakage and improving reliability. Third, in this embodiment, the transition block assembly 7 is welded to the first pipe 1, second pipe 2, and connecting pipe 20, enabling spatial connectivity of the flow channel.
