Description

[0002] With the rapid development of technology, electronic devices and electronic equipment are gradually developing towards being thinner and more efficient to meet the diverse needs of users. Therefore, electronic devices and electronic equipment also need to have a good heat dissipation structure to dissipate heat when in use, so as to ensure that the electronic devices and electronic equipment can maintain high performance and maintain their service life. In recent years, liquid cooling has gradually been widely used in the field of heat dissipation. It mainly attaches the liquid cooling head to the heat source, absorbs the heat generated by the heat source through the coolant in the liquid cooling head, and transmits the coolant to the liquid cooling radiator through the infusion tube for heat dissipation.

[0003] However, as the performance of chips, circuit boards or motherboards improves, the heat energy generated by them also increases significantly, making it impossible for the liquid cooling radiator of conventional liquid cooling to quickly cool the heat source. In addition, as electronic devices and electronic equipment become thinner and lighter, the substrate (such as circuit boards, motherboards) with heat sources needs to be reduced in area while also retaining the location of chips, circuits or other electronic components as much as possible, so there is not enough space to reserve for the installation of liquid cooling radiators.

[0033] The base 10 is disposed on the substrate A, and the base 10 mainly includes a liquid cooling head 11 and a mounting frame 12. The liquid cooling head 11 in the present embodiment is generally a rectangular block, but the present invention is not limited thereto. The liquid cooling head 11 is attached to the heat source B, and the liquid cooling head 11 has a first side surface 111 and a second side surface 112 adjacent to each other. The mounting frame 12 is configured corresponding to the liquid cooling head 11. Specifically, the base 10 in the present embodiment also includes a support frame 13, the support frame 13 is fixed to the liquid cooling head 11 to facilitate the liquid cooling head 11 to be attached to the heat source B, and the mounting frame 12 is fixed to the support frame 13, but the present invention is not limited thereto, for example, the mounting frame 12 can also be directly fixed to the liquid cooling head 11 or the substrate A.

[0034] The pump 20 in this embodiment is disposed in the liquid cooling head 11, so as to drive a cooling liquid (not shown) to flow in the liquid cooling head 11. The liquid cooling head 11 and the pump 20 are well known to people with common knowledge in the art, so the specific structures of the liquid cooling head 11 and the pump 20 are not particularly described in detail here. Of course, the pump 20 can also be disposed in the first liquid cooling row 31 or the second liquid cooling row 32 in the liquid cooling row group 30 described later, or the pump 20 is disposed in the liquid cooling head 11, the first liquid cooling row 31 and the second liquid cooling row 32.

[0035] The liquid cooling row group 30 is fixed on the mounting frame 12, and the liquid cooling row group 30 includes a first liquid cooling row 31 and a second liquid cooling row 32 which are connected to each other. Specifically, the mounting frame 12 includes a bottom plate 121, a first mounting portion 122 and a second mounting portion 123. In this embodiment, the bottom plate 121 is fixed on the support frame 13, and the first mounting portion 122 and the second mounting portion 123 are respectively vertically connected to different sides of the bottom plate 121, but the utility model is not limited thereto. For example, the first mounting portion 122 and the second mounting portion 123 can also be obliquely connected to the bottom plate 121 or connected to the center of the bottom plate 121. The first liquid cooling row 31 is fixed to the first mounting portion 122 and is configured corresponding to the first side surface 111. The second liquid cooling row 32 is fixed to the second mounting portion 123 and is configured corresponding to the second side surface 112.

[0036] In the present embodiment, the bottom plate 121 of the mounting frame 12 is generally L-shaped, so the first mounting portion 122 and the second mounting portion 123 are perpendicular to each other and are L-shaped, so that the first liquid-cooling row 31 and the second liquid-cooling row 32 are also perpendicular to each other and are L-shaped, but the present invention is not limited thereto. The angle formed between the first mounting portion 122 and the second mounting portion 123 can be between 60° and 140°, so that the angle formed between the first liquid-cooling row 31 and the second liquid-cooling row 32 is also between 60° and 140°. Thus, since the angle between the first liquid-cooling row 31 and the second liquid-cooling row 32 is between 60° and 140°, the first liquid-cooling row 31 and the second liquid-cooling row 32 can be arranged on the adjacent two sides of the liquid-cooling head 11, which can not only increase the heat dissipation volume through the first liquid-cooling row 31 and the second liquid-cooling row 32 to improve the heat dissipation efficiency, but also effectively save the assembly space occupied by the first liquid-cooling row 31 and the second liquid-cooling row 32, which is beneficial to the overall installation space configuration and the use planning of the substrate A.

[0037] For further instructions, see Figures 3 to 5 As shown, the first liquid cooling row 31 has a first liquid inlet flow diversion chamber 311, a plurality of first liquid inlet heat dissipation structures 312, a first liquid inlet confluence chamber 313, a first liquid outlet flow diversion chamber 314, a plurality of first liquid outlet heat dissipation structures 315 and a first liquid outlet confluence chamber 316.

Each of the first liquid inlet heat dissipation structures 312 is a finned pipeline parallel to each other and communicates with the first liquid inlet flow diversion chamber 311 and the first liquid inlet confluence chamber 313, that is, each of the first liquid inlet heat dissipation structures 312 is connected between the first liquid inlet flow diversion chamber 311 and the first liquid inlet confluence chamber 313. Each first liquid outlet heat dissipation structure 315 is a finned pipe parallel to each other and communicates with the first liquid outlet diversion cavity 314 and the first liquid outlet confluence cavity 316 , that is, each first liquid outlet heat dissipation structure 315 is connected between the first liquid outlet diversion cavity 314 and the first liquid outlet confluence cavity 316 .

[0038] Please read next Figure 3 and Figure 6As shown, the second liquid cooling row 32 has a second liquid inlet flow diversion chamber 321, a plurality of second liquid inlet heat dissipation structures 322, a water tank 323, a plurality of second liquid outlet heat dissipation structures 324 and a second liquid outlet confluence chamber 325. The second liquid inlet flow diversion chamber 321 and the second liquid outlet confluence chamber 325 are adjacently arranged on one side of the second liquid cooling row 32, and the water tank 323 is arranged on the other side of the second liquid cooling row 32. Each second liquid inlet heat dissipation structure 322 is a finned pipe parallel to each other and connects the second liquid inlet flow diversion chamber 321 and the water tank 323, that is, each second liquid inlet heat dissipation structure 322 is connected between the second liquid inlet flow diversion chamber 321 and the water tank 323. Each second liquid outlet heat dissipation structure 324 is a finned pipe parallel to each other and connects the water tank 323 and the second liquid outlet confluence chamber 325, that is, each second liquid outlet heat dissipation structure 324 is connected between the water tank 323 and the second liquid outlet confluence chamber 325.

[0039] For further instructions, see Figure 3 and Figure 6 As shown, the liquid cooling row assembly 30 further includes a pair of connecting pipes 33. One connecting pipe 33 connects the first liquid inlet confluence chamber 313 and the second liquid inlet diversion chamber 321, and the other connecting pipe 33 connects the second liquid outlet confluence chamber 325 and the first liquid outlet diversion chamber 314. Figures 1 to 4 As shown, the liquid cooling device of the present invention further includes a pair of liquid infusion tubes 40. The first liquid inlet diversion chamber 311 of the first liquid cooling row 31 has a liquid inlet 3111, and the first liquid outlet confluence chamber 316 of the first liquid cooling row 31 has a liquid outlet 3161. One of the liquid infusion tubes 40 is connected to the liquid inlet 3111 and the liquid cooling head 11, and the other liquid infusion tube 40 is connected to the liquid outlet 3161 and the liquid cooling head 11. Thus, the cooling liquid pushed by the pump 20 in the liquid cooling head 11 can flow back to the liquid cooling head 11 in sequence through the liquid inlet 40, the liquid inlet 3111, the first liquid inlet diversion chamber 311, each first liquid inlet heat dissipation structure 312, the first liquid inlet confluence chamber 313, the connecting tube 33, the second liquid inlet diversion chamber 321, each second liquid inlet heat dissipation structure 322, the water tank 323, each second liquid outlet heat dissipation structure 324, the second liquid outlet confluence chamber 325, another connecting tube 33, the first liquid outlet diversion chamber 314, each first liquid outlet heat dissipation structure 315, the first liquid outlet confluence chamber 316, the liquid outlet 3161 and another liquid inlet tube 40 to form a circulation, so that the cooling liquid can bring the heat energy of the heat source B absorbed by the liquid cooling head 11 to the first liquid cooling row 31 and the second liquid cooling row 32 for heat dissipation.

[0040] See also Figures 1 to 3As shown, the liquid cooling device of the present invention further includes a first fan 50 and a second fan 60, and the first fan 50 and the second fan 60 are arranged on the liquid cooling row group 30. Specifically, the first fan 50 is arranged on the first liquid cooling row 31 and corresponds to each first liquid inlet heat dissipation structure 312 and each first liquid outlet heat dissipation structure 315, and the second fan 60 is arranged on the second liquid cooling row 32 and corresponds to each second liquid inlet heat dissipation structure 322 and each second liquid outlet heat dissipation structure 324. In this way, the first fan 50 can be used to perform air cooling and heat dissipation on each first liquid inlet heat dissipation structure 312 and each first liquid outlet heat dissipation structure 315 of the first liquid cooling row 31, and the second fan 60 can be used to perform air cooling and heat dissipation on each second liquid inlet heat dissipation structure 322 and each second liquid outlet heat dissipation structure 324 of the second liquid cooling row 32, thereby greatly improving the heat dissipation efficiency of the first liquid cooling row 31 and the second liquid cooling row 32. In addition, since the angle formed between the first liquid-cooling row 31 and the second liquid-cooling row 32 is between 60° and 140°, and the first liquid-cooling row 31 in the present embodiment is perpendicular to the second liquid-cooling row 32 and is L-shaped, the first fan 50 and the second fan 60 can provide a good air-cooling heat dissipation effect and avoid the airflows generated by the first fan 50 and the second fan 60 from interfering with each other.

[0041] The liquid-cooled heat dissipation device of the present invention is configured on two adjacent sides of the liquid cooling head 11 by configuring the first liquid cooling row 31 and the second liquid cooling row 32. Not only can the heat dissipation volume be increased by the first liquid cooling row 31 and the second liquid cooling row 32 to improve the heat dissipation efficiency, but also the assembly space occupied by the first liquid cooling row 31 and the second liquid cooling row 32 can be effectively saved, which is beneficial to the overall installation space configuration and the use planning of the substrate A.
