Description

Technical Field

[0001] The invention relates to the technical field of cooling plates, and in particular to a built-in tubular flow channel plate and an assembling method thereof. Background Art

[0002] As electronic technology develops towards integration and high power, higher demands are placed on cooling and heat dissipation technology. Traditional natural cooling and forced air cooling can no longer meet the heat dissipation requirements of high-power devices. Liquid cooling technology has become one of the most effective heat dissipation methods. At present, the chassis can be cooled by a liquid cooling carrier structure. The manifold plate is the main heat dissipation component of the liquid cooling carrier structure. The coolant circulates in the flow channel of the manifold plate through a liquid pump to take away the heat generated by the chassis. At present, the manifold plate mainly includes two types: metal matrix integrated manifold plate and built-in tube manifold plate.

[0003] The existing built-in tubular flow channel plate is processed by cutting and the pipes are tinned and brazed (or glued). The material of the built-in pipe is generally copper alloy, and tinned brazing or gluing is used to form it, which solves the galvanic corrosion of the material to a certain extent. However, the main problems include: the built-in pipe and the corresponding pipe groove are not tightly matched, the heat conduction is insufficient, the thermal resistance of the liquid cooling carrier structure is large, and the heat dissipation requirements of high-power devices cannot be met; the quality of brazing and gluing is unstable, and the thermal resistance of the brazing agent and the glue agent themselves is large, which cannot meet the heat dissipation requirements of high-power devices.

[0055] In addition, 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] Embodiment 1:

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

[0058] The first substrate 5 and the second substrate 6 are respectively arranged on two opposite sides of the liquid cooling carrier structure, the first pipeline 1 is arranged on the first substrate 5, the first cover plate 3 closes the area on the first substrate 5 where the first pipeline 1 is placed, the first cover plate 3 and the first substrate 5 are fixedly connected, and the first pipeline 1 is respectively interference fit with the first cover plate 3 and the first substrate 5 to minimize the gap between the three and reduce thermal resistance.

[0059] The second pipeline 2 is arranged on the second substrate 6, the second cover plate 4 closes the area on the second substrate 6 where the second pipeline 2 is placed, the second cover plate 4 and the second substrate 6 are fixedly connected, and the second pipeline 2 is interference fit with the second cover plate 4 and the second substrate 6 respectively, so as to eliminate the gap between the three as much as possible and reduce thermal resistance.

[0060] In order to allow the 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 pipeline 1 and the second pipeline 2 to allow the coolant to flow in the first pipeline 1 and the second pipeline 2 .

[0061] In the existing built-in tubular flow channel structure, the first pipeline 1 and the second pipeline 2 are mostly connected to other components by brazing and bonding. However, the stability of brazing and bonding is poor for metal pipelines, and the thermal resistance of the brazing agent and the bonding agent is large, 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 further includes an adapter block assembly 7, which is disposed at the openings of the first pipeline 1, the second pipeline 2 and the connecting pipe 20. Each adapter block in the adapter block assembly 7 is provided with a hole system such as a hole matching the diameter of the first pipeline 1 and the second pipeline 2, a flow channel turning hole for the coolant, and a connection fastening and mounting hole of the adapter block, and the hole system can be formed by cutting.

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

[0063] The present invention presses and interferes with the first pipeline 1, the first substrate 5 and the first cover plate 3, and presses and interferes with the second pipeline 2, the second substrate 6 and the second cover plate 4, and then welds the first cover plate 3 to the first substrate 5, and the second cover plate 4 to the second substrate 6, so that the pipelines, the substrates and the cover plates are closely matched, and gaps between the three are effectively avoided to reduce thermal resistance, thereby achieving the purpose of efficient heat dissipation, and the materials or welding methods used for welding between the first pipeline 1, the second pipeline 2 and the adapter block assembly 7 will not affect the heat dissipation performance of the flow channel plate.

[0064] In order to enable the first pipeline 1 to be installed with the first substrate 5 as close to a gap as possible, 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, and the edge of the first cover plate 3 is interference fit with the bottom surface of the first receiving groove 50; a first arc groove 51 is provided at the bottom of the first receiving groove 50, and the first arc groove 51 is used to place the first pipeline 1. In an actual application scenario, when the first pipeline 1 is placed in the first arc 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 groove 51 cannot completely accommodate the first pipeline 1, and a part of the first pipeline 1 will protrude from the first arc groove 51. At the same time, considering the tightness of the fit between the first pipeline 1 and the first cover plate 3, as shown Figure 6 As shown, the first cover plate 3 is provided with a second arc groove 30 on one side abutting against the first receiving groove 50, and the second arc groove 30 is coupled with the portion of the first pipeline 1 protruding from the bottom of the first receiving groove 50. That is, the first pipeline 1 is respectively interference-fitted with the first arc groove 51 and the second arc groove 30.

[0065] The same as the first pipeline 1, the first substrate 5 and the first cover plate 3 described above. Figure 7As shown, the second substrate 6 is provided with a second receiving groove 60, the edge of the second cover plate 4 is placed in the second receiving groove 60, and the edge of the second cover plate 4 is interference fit with the bottom surface of the second receiving groove 60; the bottom of the second receiving groove 60 is provided with a third arc groove 61, and the third arc groove 61 is used to place the second pipeline 2. The second cover plate 4 is provided with a fourth arc groove 40 on the side abutting against the second receiving groove 60, and the fourth arc groove 40 is coupled with the part of the second pipeline 2 protruding from the bottom of the second receiving groove 60, and the second pipeline 2 is respectively interference fit with the third arc groove 61 and the fourth arc groove 40. Its structural design purpose is the same as that of the first pipeline 1, the first substrate 5 and the first cover plate 3, and will not be repeated here.

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

[0067] To facilitate the connection between pipelines and avoid the problem of unstable connection quality caused by welding or gluing, such as Fig. 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 pipeline 1, the second adapter block 71 is fixedly connected to the other end of the first pipeline 1, the third adapter block 72 is fixedly connected to one end of the second pipeline 2, and the fourth adapter block 73 is fixedly connected to the other end of the second pipeline 2; the two ends of the connecting pipe 20 are respectively fixedly connected to the second adapter block 71 and the fourth adapter block 73. Among them, the first adapter block 70, the second adapter block 71, the third adapter block 72 and the fourth adapter block 73 are all provided with a hole system connected to the first pipeline 1, the second pipeline 2 and the connecting pipe 20, so that the coolant flows in the first pipeline 1, the second pipeline 2 and the connecting pipe 20.

[0068] In one embodiment, see Fig. 9 As shown, the connecting pipe 20 is in the form of a straight pipe, and the straight pipe is arranged between the second adapter block 71 and the fourth adapter block 73. When the connecting pipe 20 is a straight pipe, the function of the connecting pipe 20 is to make the first pipeline 1 and the second pipeline 2 conduct, and a cover plate is arranged outside the connecting pipe 20 for shielding.

[0069] In actual application scenarios, during the operation of the chassis 10, some electronic components inside it generate significant heat. The two-sided heat dissipation method cannot meet the heat dissipation requirements of the electronic components with severe heat generation. If you want to achieve a better cooling effect on the chassis 10, the cooling pipes should cover more areas of the chassis 10, such as Fig.10As shown, a third pipeline 11 is further provided between the first pipeline 1 and the second pipeline 2, and the third pipeline 11 is in the form of an S-shaped pipe; a first set of solenoid valves are provided at both ends of the connecting pipe 20, and the first set of solenoid valves are used to open and close both ends of the connecting pipe 20; a second set of solenoid valves are provided at both ends of the third pipeline 11, and the second set of solenoid valves are used to open and close both ends of the third pipeline 11. The first set of solenoid valves includes two solenoid valves, one of which is provided in the second adapter block 71, and the other is provided in the fourth adapter block 73; similarly, the second set of solenoid valves includes two solenoid valves, one of which is provided in the second adapter block 71, and the other is provided in the fourth adapter block 73.

[0070] In the actual operation scenario, if the three sides of the chassis 10 need to be cooled, the solenoid valves at both ends of the connecting pipe 20 are closed, and the solenoid valves at both ends of the third pipeline 11 are opened, so that the coolant can flow from the first pipeline 1 through the third pipeline 11 to the second pipeline 2, thereby cooling the three sides of the chassis 10; if the surface where the third pipeline 11 is located does not need to be cooled, and the surfaces where the first pipeline 1 and the second pipeline 2 are located are concentratedly cooled, the solenoid valves at both ends of the third pipeline 11 are closed, and the solenoid valves at both ends of the connecting pipe 20 are opened, so that the coolant flows from the first pipeline 1 through the connecting pipe 20 to the second pipeline 2. The shape of the third pipeline 11 is set to an S-shaped pipe, so that it and the first pipeline 1 and the second pipeline 2 cover the three-side area of ​​the liquid cooling carrier structure, so as to achieve a wider coverage range of the cooling pipeline and a better cooling effect. Similar to the first pipeline 1 and the second pipeline 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 installation.

[0071] See also Fig. 9 As shown, the built-in tubular flow channel plate is provided with a liquid inlet pipe 8 and a liquid outlet pipe 9, and the adapter block assembly 7 also includes a fifth adapter block 74 and a sixth adapter block 75. One end of the liquid inlet pipe 8 is fixedly connected to the fifth adapter block 74, and the other end of the liquid inlet pipe 8 is fixedly connected to the first adapter block 70; one end of the liquid outlet pipe 9 is fixedly connected to the sixth adapter block 75, and the other end of the liquid outlet pipe 9 is fixedly connected to the third adapter block 72.

[0072] 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 described in the above solution are all designed with fixing holes for fixing. Fig.11 As shown in the dotted box, it is used to fix each transfer block. Fig.11Only the fixing holes of the fifth adapter block 74 and the sixth adapter block 75 are shown, and the fixing holes of the first adapter block 70, the second adapter block 71, the third adapter block 72 and the fourth adapter block 73 are Fig.11 The fixing holes shown in the figure are consistent in shape and are all arranged 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 position shown in the figure as an example). The first pipeline 1, the second pipeline 2 and the connecting pipe 20 of the S-shaped pipe are bent and formed by a mold.

[0073] Based on the above solution, an embodiment of the present invention further provides an assembly method of a built-in tubular flow channel plate, which is applicable to the built-in tubular flow channel plate described in the above solution, such as Fig.12 As shown, including:

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

[0075] In step S2 , the first cover plate 3 is covered on the first pipeline 1 , and the first cover plate 3 is pressed into the first base plate 5 by a hydraulic press, and the first cover plate 3 and the first base plate 5 are welded and fixed.

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