Description

Technical Field

[0001] The invention relates to the field of liquid cooling and heat dissipation, and in particular to a dual-pump liquid cooling device. Background Art

[0002] In a liquid cooling system, the coolant is sealed and filled in a closed loop for circulation, and the coolant is used as a medium to carry the heat from the heat source to the heat sink for cooling and dissipation. Therefore, a pump is mostly used in liquid cooling systems to promote the flow of coolant, and the faster the flow rate of the coolant, the better the heat dissipation efficiency of the entire liquid cooling system.

[0003] However, as electronic technology develops towards thinness and high performance, the heat generated has also increased significantly, but the cooling device with a single pump can only push the flow rate of the coolant at a limited rate, resulting in insufficient heat dissipation efficiency. In addition, in order to cope with the thin design, when the overall volume of the liquid cooling system is reduced, the capacity of the coolant that can be accommodated is also relatively reduced, so that after a period of use, the liquid cooling system will be insufficient due to coolant evaporation or leakage, thereby affecting the operation of the liquid cooling system. Summary of the invention

[0004] The main purpose of the present invention is to effectively increase the flow rate of coolant in a dual-pump liquid cooling device to improve heat dissipation efficiency and avoid the situation where the coolant is insufficient due to evaporation or leakage after long-term use.

[0006] In one embodiment of the present invention, the base has a plurality of fins arranged parallel to each other, and a plurality of flow channels are formed between the fins. The fins and the partition assembly together divide the heat exchange chamber into flow channels and a pair of inlet areas. The two ends of each flow channel are connected to the perforations via the inlet areas, and each flow channel is connected to the liquid outlet channel via a through groove group.

[0007] In an embodiment of the present invention, each through hole is respectively disposed at a diagonal position of each fin.

[0010] In one embodiment of the present invention, the partition assembly further includes an abutment sheet, which is disposed between the guide plate and the base. The abutment sheet has a pair of limit baffles, and each limit baffle is limited to two opposite sides of the guide plate.

[0011] In one embodiment of the present invention, the partition assembly further includes a pair of filling blocks, each of which is disposed on two opposite sides of the guide plate, and the through groove group is located between the filling blocks.

Therefore, after the coolant enters from the liquid inlet interface, it can first be collected and converged in the liquid collecting cavity, and then enter the tanks, channels, perforations and through-slot groups in sequence through the suction force generated by the operation of each pump to enter the heat exchange cavity, thereby effectively increasing the flow rate of the coolant in the dual-pump liquid cooling device to improve the heat dissipation efficiency, and avoiding the situation where the coolant is insufficient due to evaporation or leakage after long-term use, while improving the sealing of the base and reducing the assembly complexity and maintenance cost.

[0031] The detailed description and technical contents of the present invention will be described as follows with reference to the drawings. However, the drawings are only for illustration purposes and are not intended to limit the present invention.

[0032] The present invention provides a dual-pump liquid cooling device, which can allow a cooling liquid to flow through. Figures 1 to 4 As shown, the dual-pump liquid cooling device of the present invention includes a base 10 , a pair of pumps 20 , a partition assembly 30 and a base 40 .

[0033] The base 10 is disposed on the base 40 along an up-down direction D. In the present embodiment, the base 10 is generally rectangular, but the present invention is not limited thereto. The base 10 has a liquid inlet interface 111, a liquid outlet interface 112, a liquid collecting chamber 113, a pair of containers 114, a pair of channels 115 and a liquid outlet channel 116. In the present embodiment, the liquid inlet interface 111 and the liquid outlet interface 112 are both located on the same side of the base 10, so as to facilitate the user to wire a pair of infusion tubes (not shown) connected to the liquid inlet interface 111 and the liquid outlet interface 112, but in other embodiments, the liquid inlet interface 111 and the liquid outlet interface 112 can also be located on different sides of the base 10. Please refer to Figures 1 to 4 and Figure 7 As shown, the liquid inlet interface 111 is connected to the liquid collecting chamber 113, and the liquid outlet interface 112 is connected to the liquid outlet channel 116. Specifically, the liquid collecting chamber 113 and the liquid outlet channel 116 are both formed at the bottom of the base 10, and the liquid collecting chamber 113 and the liquid outlet channel 116 are not directly connected to each other. Figures 1 to 4 and Figure 6As shown, each container 114 is arranged in parallel on the top of the base 10, and each container 114 is connected to the liquid collecting cavity 113. In other words, each container 114 is located above the liquid collecting cavity 113 along the up-down direction D, and the liquid inlet interface 111 can be connected to each container 114 through the liquid collecting cavity 113, that is, Figure 6 and Figure 7 As shown. Each channel 115 is respectively configured corresponding to each receiving groove 114 and is respectively connected to each receiving groove 114, and each channel 115 is located on both sides of the liquid collecting cavity 113. In this embodiment, each channel 115 is respectively arranged at the diagonal of the liquid collecting cavity 113, and each channel 115 extends in the base 10 along the up-down direction D, but the present invention is not limited thereto, for example, each channel 115 can also be arranged on opposite sides of the liquid collecting cavity 113, or each channel 115 can also extend in the base 10 obliquely.

[0034] See also Figures 1 to 4 and Figure 6 As shown, each pump 20 is configured to correspond to each container 114. Specifically, the base 10 includes a body 11 and a mounting frame 12. The body 11 is an integrally formed component, and the body 11 has the aforementioned liquid inlet interface 111, liquid outlet interface 112, liquid collecting chamber 113, each container 114, each channel 115 and liquid outlet channel 116. The mounting frame 12 has a pair of mounting grooves 121. The mounting frame 12 is arranged on the top of the body 11 and covers each container 114, so that each mounting groove 121 is configured to correspond to each container 114. In other words, each mounting groove 121 and each container 114 are respectively located on the upper and lower opposite sides of the mounting frame 12. Each pump 20 includes a stator assembly 21 and a rotor assembly 22. Each rotor assembly 22 is respectively arranged in each container 114, and each stator assembly 21 is respectively arranged in each mounting groove 121. In other words, each stator assembly 21 is located above each corresponding rotor assembly 22 along the up-down direction D and surrounds a portion of each corresponding rotor assembly 22. Since the specific structure and operation principle of the pump 20 are well known to those skilled in the art, they will not be described in detail here.

[0035] See also Figures 1 to 5 and Figures 8 to 9As shown, the partition assembly 30 covers the bottom of the liquid collecting chamber 113. Specifically, the partition assembly 30 abuts between the base 40 and the base 10, so that the liquid collecting chamber 113 is substantially located between the partition assembly 30 and each container 114. The partition assembly 30 has a pair of through holes 311 and a through groove group 301. A heat exchange chamber 41 is formed between the partition assembly 30 and the base 40. Each channel 115 is connected to the heat exchange chamber 41 through each through hole 311, and the heat exchange chamber 41 is connected to the liquid outlet channel 116 through the through groove group 301. Thus, after the coolant enters the liquid inlet interface 111, it can first be collected and converged in the liquid collecting chamber 113 of the base 10, and then pumped into each container 114 through the suction force generated by each pump 20 when it is running, and then enter the heat exchange chamber 41 through each channel 115 through each corresponding perforation 311, and then enter the liquid outlet channel 116 of the base 10 through the through groove group 301 of the partition component 30, and finally leave from the liquid outlet interface 112. Therefore, the setting of the liquid collecting chamber 113 can not only effectively increase the flow rate of the coolant in the dual-pump liquid cooling device to improve the heat dissipation efficiency, but also avoid the situation where the coolant is insufficient due to evaporation or leakage after long-term use. In addition, since the main body 11 of the base 10 is an integrally formed component rather than a two-piece component, it can also effectively avoid the coolant from leaking from the joints of the two-piece structure, thereby improving the sealing and reducing the assembly complexity and maintenance cost.

[0036] To further explain, the base 40 has a plurality of fins 42 arranged in parallel with each other. The fins 42 are arranged in parallel with each other on the side of the base 40 facing the base 10 and the partition component 30, that is, the fins 42 are arranged on the top of the base 40. A plurality of flow channels 43 parallel to each other are formed between the fins 42. Both ends of each flow channel 43 are connected to each through hole 311, and each flow channel 43 is connected to the liquid outlet channel 116 of the base 10 through the through groove group 301 of the partition component 30. Specifically, each fin 42 and a part of the partition component 30 together divide the heat exchange chamber 41 into each flow channel 43 and a pair of inlet areas 411. The two ends of each flow channel 43 are respectively connected to each inlet area 411, that is, each fin 42 and each flow channel 43 are vertically arranged between each inlet area 411. In other words, part of the partition assembly 30 and each inflow area 411 are arranged around each fin 42 and each flow channel 43 and surround each fin 42 and each flow channel 43. Each through hole 311 is connected to each flow channel 43 through each inflow area 411. In this embodiment, each through hole 311 is respectively arranged at the diagonal of each fin 42, so that the coolant can flow into each flow channel 43 evenly from each inflow area 411, but the present invention is not limited thereto. In addition, the through groove group 301 in this embodiment is located at the center of each fin 42, so that the coolant can enter from both ends of each flow channel 43 and converge at the center to enter the through groove group 301. Thus, when the coolant enters the heat exchange chamber 41 through the corresponding perforations 311 via the channels 115 , the coolant first enters the inlet areas 411 and flows into the flow channels 43 between the fins 42 , and finally leaves the heat exchange chamber 41 through the through groove group 301 of the partition component 30 .

[0037] Please read next Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the partition assembly 30 includes a partition plate 31, a guide plate 32, an abutment sheet 33 and a pair of filling blocks 34. In this embodiment, the partition plate 31 and the abutment sheet 33 are both metal parts, and the guide plate 32 and each filling block 34 are both made of silicone or rubber material, but the present invention is not limited to this. Each filling block 34 is disposed on the base 40, and each filling block 34 is parallel to each fin 42 and is located on both sides of each fin 42. In this embodiment, as shown in FIG. Figure 5As shown, the cross-sectional shape of each plugging block 34 along the direction in which the liquid inlet interface 111 or the liquid outlet interface 112 is set is roughly lightning-shaped and is symmetrically arranged relative to another plugging block 34, so that it can be placed on the step difference on both sides of the base 40 and carry the abutment sheet 33. The partition plate 31 is abutted between the base 10 and the guide plate 32, and the partition plate 31 has the aforementioned perforations 311. The abutment sheet 33 is arranged on each fin 42 of the base 40 and each plugging block 34 along the up and down direction D. The guide plate 32 is abutted and clamped between the abutment sheet 33 and the partition plate 31, and the guide plate 32 is located between each perforation 311 and each inflow area 411. In other words, the abutment sheet 33 is arranged between the guide plate 32 and each fin 42 of the base 40 and each plugging block 34, and each plugging block 34 is respectively arranged on the opposite sides of the guide plate 32 so that the through groove group 301 is located between each plugging block 34. Therefore, the filling blocks 34 , the contact pieces 33 , the guide plates 32 and the partition plates 31 of the partition assembly 30 are stacked in sequence along the up-down direction D on the base 40 .

[0038] To further explain, the partition plate 31 has a wall 312, and the guide plate 32 has a groove 321. Specifically, the wall 312 extends from the partition plate 31 toward one side of the guide plate 32 and is roughly in the shape of a rectangular frame. The groove 321 is recessed from the periphery of the top of the guide plate 32 to form a corresponding rectangular groove. The wall 312 of the partition plate 31 is clamped in the groove 321 of the guide plate 32, so that the top of the guide plate 32 is confined within the wall 312 at the bottom of the partition plate 31. In this embodiment, the partition plate 31 also has a positioning protrusion 313 on the side facing the guide plate 32, and the guide plate 32 also has a positioning recessed hole 322 on the side facing the partition plate 31. The positioning protrusion 313 can be stuck in the positioning recessed hole 322 to further position the partition plate 31 and the guide, but in other embodiments, the positioning protrusion 313 can also be set on the guide plate 32, and the positioning recessed hole 322 is set on the partition plate 31.

[0039] Furthermore, a pair of limiting baffles 331 are provided on opposite sides of the contact piece 33. Each limiting baffle 331 of the contact piece 33 extends vertically toward the guide plate 32 along the up-down direction D, thereby being limited to opposite sides of the guide plate 32. Each positioning baffle of the guide plate 32 extends vertically toward the contact piece 33 along the up-down direction D, thereby being limited to opposite sides of the contact piece 33 and being located between each limiting baffle 331. In other words, each limiting baffle 331 of the contact piece 33 limits one opposite side of the guide plate 32, and each filling block 34 limits the other opposite sides of the guide plate 32, thereby further limiting the guide plate 32 from moving forward, backward, leftward, or rightward.

[0040] Therefore, the partition plate 31 and the guide plate 32 can be mutually embedded and positioned without relative displacement in the front, rear, left and right directions, and the guide plate 32 is firmly clamped between the partition plate 31 and the abutment sheet 33 to ensure that it cannot be displaced in the up-down direction D, and the guide plate 32, each packing block 34 and the abutment sheet 33 can also be mutually positioned without relative displacement. In addition, since the guide plate 32 made of silicone or rubber is sandwiched between the partition plate 31 and the abutment sheet 33 of the metal part, it can effectively prevent the strong impact of the coolant from the bottom to the top in the up-down direction D from causing the guide plate 32 to be deformed or displaced, thereby ensuring that the coolant can flow stably when flowing through the partition assembly 30.

[0041] For further explanation, see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the through slot group 301 includes a through hole 3011, a first through slot 3012, a second through slot 3013 and a third through slot 3014. The through hole 3011 and the first through slot 3012 are arranged on the partition plate 31. Specifically, the through hole 3011 is a circular hole and penetrates the partition plate 31 along the up-down direction D, and the first through slot 3012 is arranged at the bottom of the partition plate 31 and is connected to the through hole 3011. In this embodiment, the first through slot 3012 extends from the bottom of the partition plate 31 toward the through hole 3011 in an inclined manner, so that the coolant can better converge to the through hole 3011 and is not easily blocked, such as Figure 5As shown, but the present invention is not limited thereto. The partition plate 31 has an engaging protrusion 314. The engaging protrusion 314 protrudes from the partition plate 31 toward one side of the guide plate 32, and the engaging protrusion 314 is arranged around the first through groove 3012. The second through groove 3013 penetrates the guide plate 32 along the up-down direction D, and the shape of the second through groove 3013 corresponds to the shape of the engaging protrusion 314. Thereby, the engaging protrusion 314 of the partition plate 31 can be clamped in the second through groove 3013 of the guide plate 32, so as to further position the partition plate 31 and the guide plate 32. The first through groove 3012 is located in the engaging protrusion 314 and can be connected to the second through groove 3013. In this embodiment, the center of the first through groove 3012 is a circular hole, and long strip-shaped strip holes extend from the opposite sides thereof, and the diameter of the circular hole at the center is greater than the width of the strip hole, but the present invention is not limited thereto. The third through slot 3014 penetrates the contact plate 33 along the up-down direction D, and the third through slot 3014 is connected to the second through slot 3013 of the guide plate 32 and the first through slot 3012 of the partition plate 31, and is connected to the through hole 3011 of the partition plate 31. In the present embodiment, the third through slot 3014 is in a strip shape and is divided into two narrow sections and a wide section, the position of the wide section is substantially corresponding to the position of the circular hole at the center of the first through slot 3012, and each narrow section is connected to opposite sides of the wide section and is substantially corresponding to each strip hole of the first through slot 3012, but the present invention is not limited thereto.

[0042] It is worth mentioning that the through slot set 301 of the partition assembly 30 is substantially perpendicular to each fin 42 and each flow channel 43, and the through slot set 301 is substantially located at the center of each fin 42 and each flow channel 43. Figures 1 to 5 and Figure 8 For example, each fin 42 and each channel 43 are parallel to the front-to-back direction of the base 10 and the base 40 (i.e., the direction in which the liquid inlet interface 111 and the liquid outlet interface 112 are arranged), and the first through slot 3012 and the third through slot 3014 of the through slot group 301 are parallel to the left-right direction of the base 10 and the base 40, so the first through slot 3012 and the third through slot 3014 are perpendicular to each fin 42 and each channel 43. Therefore, when the coolant enters each channel 43 from each inlet area 411, it will flow to the center of each fin 42 and each channel 43, and then enter the third through slot 3014, the second through slot 3013, the first through slot 3012 and the through hole 3011 from bottom to top along the up-down direction D, and then enter the liquid outlet channel 116 of the base 10 through the partition component 30. When the coolant passes through the third through groove 3014 and the first through groove 3012 of the partition assembly 30 , it will be affected by the narrow sections and the strip holes respectively and gradually converge toward the wide section and the circular holes, thereby converging into the through hole 3011 of the partition plate 31 and flowing out.

[0043] The dual-pump liquid cooling device of the present invention forms a liquid collecting chamber 113 on the base 10, and each pump 20 is arranged in parallel in each container 114 of the base 10. Therefore, after the coolant enters from the liquid inlet interface 111, it can first be collected and converged in the liquid collecting chamber 113, and then enter the each container 114, each channel 115, each through hole 311 and the through groove group 301 in sequence through the suction force generated when each pump 20 is running, and then enter the heat exchange chamber 41, thereby effectively increasing the flow rate of the coolant in the dual-pump liquid cooling device to improve the heat dissipation efficiency, and avoiding the situation where the coolant is insufficient due to evaporation or leakage after long-term use, while improving the sealing of the base 10 and reducing the assembly complexity and maintenance cost.

[0044] In summary, the above disclosure of the present invention is to enable those with ordinary knowledge in the field to clearly understand the technical content of the present invention and implement it accordingly, and is not intended to limit the scope of patent protection of the present invention. In addition, the present invention may of course have other unlisted embodiments. Without departing from the spirit and essence of the present invention, those familiar with the art should be able to evolve various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the patent applied for by the present invention.
