Description

Modular heat sink assembly and air-to-liquid cooling cabinet using the same TECHNICAL FIELD

[0001] The present application relates to a heat sink assembly structure, in particular to a modular heat sink assembly and air-to-liquid cooling cabinet using the same, which realizes minimization by integrating the modular heat sink assembly, so as to install different numbers of modular heat sink assemblies on the air-to-liquid cooling cabinet according to the heat dissipation wattage requirement of customers, thereby shortening the development time of the heat sink, reducing the development cost and product cost. BACKGROUND

[0002] In the current market, air-to-liquid (ATL) cooling solutions can provide customers with the required heat dissipation wattage, and suppliers can design corresponding heat sinks or heat sink assembly structures according to the requirements. However, different heat sinks or heat sinks often need to be designed for different wattage heat dissipation requirements. However, the parts in such assembly structures have poor universality, consume a large amount of research and development manpower, and are difficult to control the quality, which is not conducive to reducing the cost. On the other hand, as the heat dissipation wattage requirement increases, the size and volume of the heat sink also need to increase, which also makes the transportation and assembly of the heat sink assembly structure more difficult, and the design of the flow channel sealing is also more complex.

[0003] Therefore, it is necessary to provide a modular heat sink assembly and air-to-liquid cooling cabinet using the same, which realizes minimization by integrating the modular heat sink assembly, so as to install different numbers of modular heat sink assemblies on the air-to-liquid cooling cabinet according to the heat dissipation wattage requirement of customers, thereby shortening the development time of the heat sink, reducing the development cost and product cost, and solving the defects of the known technology.

In order to maximize the heat dissipation capacity in the limited height of the accommodation space, the heat exchanger module can also be designed with an inclination angle relative to the lower shell wall of the shell and between the upper fan group and the lower fan group.

Figure 5 is a front view of the air-liquid cooling cabinet according to the first embodiment of the present application. The present application provides a modular heat sink assembly 1 and an air-liquid cooling cabinet 9 suitable for the modular heat sink assembly 1. A plurality of modular heat sink assemblies 1 are allowed to be installed in a plurality of mounting seats provided on a rear side plate 91 of the air-liquid cooling cabinet 9 in a simple and fast manner, so as to realize the application of air-assisted liquid cooling (AALC). In the present embodiment, the modular heat sink assembly 1 comprises a housing 10, a heat exchanger module 20, and an upper fan group 30 and a lower fan group 40. The housing 10 comprises an air inlet 11, an air outlet 12, an upper housing wall 13, a lower housing wall 14, and two side walls 15, 16. The upper housing wall 13 and the lower housing wall 14 are opposite to each other, and the two side walls 15, 16 are connected between the upper housing wall 13 and the lower housing wall 14. The upper housing wall 13, the lower housing wall 14, and the two side walls 15, 16 are combined to form a containing space 100, and the containing space 100 is communicated between the air inlet 11 and the air outlet 12. The heat exchanger module 20 is connected to the upper housing wall 13, the lower housing wall 14, and the two side walls 15, 16. The body part 21 of the heat exchanger module 20 is also obliquely accommodated in the containing space 100 relative to the lower housing wall 14 of the housing 10. The upper fan group 30 and the lower fan group 40 are arranged between the upper housing wall 13 and the lower housing wall 14, connected between the two side walls 15, 16, and adjacent to the air outlet 12. The upper fan group 30 is arranged adjacent to the upper housing wall 13, and the lower fan group 40 is arranged adjacent to the lower housing wall 14. The upper fan group 30 is obliquely arranged at a first angle Al relative to the lower fan group 40 and connected between the two side walls 15, 16. In the present embodiment, the air flow generated by the upper fan group 30 and the lower fan group 40 is sucked in through the air inlet 11, flows through the heat exchanger module 20, and is discharged through the air outlet 12.

[0040] In the present embodiment, the heat exchanger module 20 comprises a body portion 21, a hot water inlet pipe 22 and a cold water outlet pipe 23, the hot water inlet pipe 22 and the cold water outlet pipe 23 are arranged at the rear end 212 of the body portion 21 and adjacent to the air outlet 12. The hot water inlet pipe 22 of the heat exchanger module 20 is above the cold water outlet pipe 23. In an embodiment, the two side plates of the body portion 21 are fixed to the two side walls 15, 16 of the housing 10 by, for example, screws or other means. In the present embodiment, the body portion 21 of the heat exchanger module 20 is obliquely accommodated in the accommodation space 100 at a second angle A2 of, for example, 30°. In other embodiments, the second angle A2 ranges between 20° and 45°. In the present embodiment, the upper fan group 30 and the lower fan group 40 are located at the front end 211 of the body portion 21 and adjacent to the air inlet 11, and the rear end 212 of the body portion 21 is connected to the lower housing wall 14. In the present embodiment, the upper fan group 30 and the lower fan group 40 each comprise five fans, which are detachably arranged on a fan plate 50, and the fan plate 50 is locked to the two side walls 15, 16 of the housing 10 by, for example, screws or other means, and is connected to the front end 211 and the bottom surface 213 of the body portion 21. In the present embodiment, the fan plate 50 can be pre-bent at a first angle A1, so that the upper fan group 30 is obliquely arranged at a first angle A1 of, for example, 110° with respect to the lower fan group 40 and is connected between the two side walls 15, 16. In other embodiments, the first angle A1 ranges between 90° and 180°. When the upper fan group 30 and the lower fan group 40 pass through the two side walls 15, 16 of the housing 10 via the fan plate 50, the lower fan group 40 is vertically arranged with respect to the lower housing wall 14 and connected between the two side walls 15, 16, and the upper fan group 30 is obliquely arranged at a first angle A1 with respect to the lower fan group 40 and connected between the two side walls 15, 16, and the first angle A1 ranges between 90° and 180°. Thus, the closed flow channel C formed between the upper fan group 30 and the lower fan group 40 and the heat exchanger module 20 is located in the accommodation space 100 of the housing 10. In the present embodiment, the cold air flow F1 generated by the upper fan group 30 and the lower fan group 40 enters the closed flow channel C from the air inlet 11, and the cold air flow F1 is heat-exchanged by the body portion 21 of the heat exchanger module 20 to form a hot air flow F2. The hot air flow F2 is discharged from the top surface 214 of the body portion 21 of the heat exchanger module 20, and the cold air flow F1 and the hot air flow F2 pass through the flow area of the body portion 21, which helps to reduce the flow resistance in the limited accommodation space 100 and enables the modular heat radiator assembly 1 to further increase the number of fans and the maximum air flow. Of course, the present application is not limited thereto.

[0041] In this embodiment, each modular heat sink assembly 1 can achieve optimal heat exchange efficiency within the limited height of the accommodation space 100, so that each modular heat sink assembly 1 has a heat dissipation capacity of 20 kW to 40 kW. When applied to the air-assisted liquid cooling gas-liquid cooling cabinet 9, the modular heat sink assembly 1 can be installed in various combinations according to requirements. In this embodiment, the gas-liquid cooling cabinet 9 includes a cabinet body 90 and four sets of modular heat sink assemblies 1'. The structures of the four modular heat sink assemblies 1' are substantially similar to those of the modular heat sink assembly 1 shown in FIGS. 1 to 3, except that the number of fans in the upper fan group 30 and the lower fan group 40 is replaced by four. Referring to FIGS. 3 to 5. In this embodiment, the four modular structures M1, M2, M3, M4 of the modular heat sink assembly 1' are allowed to be installed on the plurality of mounting seats provided on the rear side plate 91 of the cabinet body 90 in a simple and fast manner, so as to achieve the application of gas-assisted liquid cooling. In this embodiment, the rear side plate 91 of the cabinet body 90 extends along the first direction (i.e., the Z-axis direction). In this embodiment, the four modular structures M1, M2, M3, M4 are flipped to be perpendicular to the ground and parallel to the first direction (i.e., the Z-axis direction). Among them, the first modular structure M1 and the second modular structure M2 are stacked along the second direction (i.e., the Y-axis direction), the third modular structure M3 and the fourth modular structure M4 are stacked along the second direction (i.e., the Y-axis direction), the first modular structure M1 and the third modular structure M3 are stacked along the first direction (i.e., the Z-axis direction), and the second modular structure M2 and the fourth modular structure M4 are stacked along the first direction (i.e., the Z-axis direction). Thus, the four modular structures M1, M2, M3, M4 can be arranged on the rear side plate 91, and the modular heat sink assembly 1' can penetrate the rear side plate 91 along the third direction (i.e., the X-axis direction). The first direction, the second direction, and the third direction are perpendicular to each other. After the four modular heat sink assemblies 1' are arranged on the rear side plate 91, the hot water inlet pipe 22 and the cold water outlet pipe 23 of each modular heat sink assembly 1' are connected to the cooling liquid distribution unit (CDU) 92 to complete the installation. Since each modular heat sink assembly 1' can be minimized through the above arrangement, the gas-liquid cooling cabinet 9 can install different numbers of modular heat sink assemblies 1' according to the customer's heat dissipation capacity requirements, without the need to design other heat sinks or radiators. Thus, the development time of the gas-liquid cooling cabinet 9 suitable for the radiator is shortened, and the development time and product cost are effectively reduced.

Figure 7 is an exploded view of the modular heat sink assembly according to the second embodiment of the present application. Figure 8 is a sectional view of the modular heat sink assembly according to the second embodiment of the present application. Figure 9 is a perspective view of an air-liquid cooling cabinet according to the second embodiment of the present application. Figure 10 is a front view of the air-liquid cooling cabinet according to the second embodiment of the present application. In the present embodiment, the air-liquid cooling cabinet 9a and the modular heat sink assembly 1a are substantially similar to the air-liquid cooling cabinet 9 and the modular heat sink assembly 1, 1' shown in Figures 1 to 5, and the same reference numerals are used to represent the same elements, structures and functions, which will not be described again. In the present embodiment, the modular heat sink assembly 1a further comprises a flow guide plate 51 connected between the front end 211 of the body portion 21 of the heat exchanger module 20 and the upper edge of the upper fan set 30, and between the two side walls 15, 16. In the present embodiment, the fan plate 50 can be pre-bent at a first angle A1, so that the upper fan set 30 is disposed at a first angle A1, for example 135°, with respect to the lower fan set 40 and connected between the two side walls 15, 16. In the present embodiment, the fan plate 50 is further connected to the front end 211 and the bottom surface 213 of the body portion 21 of the heat exchanger module 20 through the flow guide plate 51. In this way, no matter how the first angle A1 of the upper fan set 30 with respect to the lower fan set 40 is adjusted, the closed flow channel C formed between the upper fan set 30, the lower fan set 40, the flow guide plate 51 and the heat exchanger module 20 is optimized through the connection of the flow guide plate 51. Thus, each modular heat sink assembly 1a can achieve the best heat dissipation efficiency of the heat exchanger in a limited height of the accommodation space 100, so that each modular heat sink assembly 1a has a heat dissipation capacity of 20kW to 40kW. When applied to the air-liquid cooling cabinet 9a for air-assisted liquid cooling, the modular heat sink assembly 1a can be installed in various combinations in different numbers as required, so that each modular heat sink assembly 1a can be completed by being connected to the cooling liquid distribution unit 92, effectively reducing the development time and product cost.

[0043] In this embodiment, four modular structures M1, M2, M3, M4 are horizontally arranged. The upper fan group 30 and the lower fan group 40 of each modular radiator assembly 1a respectively include five detachable fans. The first modular structure M1, the second modular structure M2, the third modular structure M3 and the fourth modular structure M4 are arranged in a stack along a first direction (i.e. the Z-axis direction) and are arranged on the rear side plate 91 in a quick and simple manner, and the modular radiator assembly 1a along a third direction (i.e. the X-axis direction) penetrates the rear side plate 91. After the four modular radiator assemblies 1a are arranged on the rear side plate 91, the hot water inlet pipe 22 and the cold water outlet pipe 23 of each modular radiator assembly 1a are connected to the cooling liquid distribution unit 92 to complete the installation, effectively reducing the development time and product cost. Of course, the number of fans of the upper fan group 30 and the lower fan group 40 and the arrangement of the plurality of modular radiator assemblies 1a can be adjusted according to actual application requirements, and the present application is not limited thereto and will not be described again.

[0044] Fig. 11 is a perspective view of a third embodiment of the modular heat sink assembly according to the present application. Fig. 12 is an exploded view of the third embodiment of the modular heat sink assembly according to the present application. Fig. 13 is a sectional view of the third embodiment of the modular heat sink assembly according to the present application. In this embodiment, the modular heat sink assembly 1b is substantially similar to the modular heat sink assembly 1 shown in Figs. 1 to 3, and the same reference numerals are used to represent the same elements, structures and functions, which will not be described again. Referring to Figs. 11 to 13. In this embodiment, the upper fan group 30 and the lower fan group 40 of the modular heat sink assembly 1b are located adjacent to the air outlet 12. The hot water inlet pipe 22 and the cold water outlet pipe 23 of the heat exchanger module 20 are located at the front end 211 of the body portion 21 and are located adjacent to the air inlet 11. The rear end 212 of the body portion 21 is connected to the lower shell wall 14 of the housing 10. In addition, the body portion 21 is obliquely accommodated in the accommodation space 100 at a second angle A2 of, for example, 30°. In other embodiments, the second angle A2 is in the range of 20° to 45°. In this embodiment, the upper fan group 30 and the lower fan group 40 are vertically arranged relative to the lower shell wall 14 and are connected between the two side walls 15, 16. That is, the first angle A1 at which the upper fan group 30 is inclined relative to the lower fan group 40 is 180°. The upper edge of the rear end 212 of the body portion 21 (i.e., one end of the top surface 214) can be connected to the lower shell wall 14 of the housing 10 by the connecting plate 52. Thus, the closed flow channel C formed between the upper fan group 30, the lower fan group 40 and the heat exchanger module 20 is located in the accommodation space 100 of the housing 10. In this embodiment, the cold air flow F1 generated by the upper fan group 30 and the lower fan group 40 enters the air inlet 11, passes through the bottom surface 213 of the body portion 21 of the heat exchanger module 20 to enter the heat exchanger module 20 for heat exchange, and the hot air flow F2 formed by the heat exchange is discharged from the top surface 214 of the body portion 21 of the heat exchanger module 20 into the closed flow channel C. The cold air flow F1 and the hot air flow F2 pass through the flow passage area of the body portion 21, which helps to reduce the flow resistance in the limited accommodation space 100 and enables the modular heat sink assembly 1b to further increase the number of fans and the maximum air flow. Of course, the present application is not limited thereto.

[0045] It should be noted that the aforementioned modular heat sink assemblies 1, 1', 1a, 1b can be combined and arranged in the air-liquid cooling cabinet 9, 9a according to actual application requirements.

[0046] In summary, the present application provides a modular heat sink assembly and its applicable air-liquid cooling cabinet. The modular heat sink assembly is integrated to achieve minimization, so that different numbers of modular heat sink assemblies can be installed on the air-liquid cooling cabinet according to the customer's heat dissipation tile number requirements, thereby shortening the development time of the heat sink, reducing the development cost and product cost. The plurality of modular heat sink assemblies allows to be installed in a simple and quick manner on the plurality of mounting seats provided on the rear side plate of the air-liquid cooling cabinet, and relative to the heat exchanger in the cabinet, to achieve the application of the air-assisted liquid cooling cabinet. Each modular heat sink assembly includes an inclined heat exchanger module provided in the housing, which cooperates with the upper fan group and the lower fan group to form a closed flow channel in the accommodation space of the housing, so as to reduce the flow resistance in the limited space. In order to maximize the heat dissipation capacity in the limited height of the accommodation space, the heat exchanger module can also be designed with an inclination angle relative to the lower shell wall of the housing and between the upper fan group and the lower fan group. The airflow flows through the large area bottom surface and top surface of the heat exchanger module, and the modular heat sink assembly can further increase the number of fans and the maximum air flow. The inclined heat exchanger module can be fixed by the two side plate metals and the two side walls of the housing. The upper fan group and the lower fan group can be fixed to the two side walls of the housing by the fan plate metal which is pre-bent to the designed angle. In addition, when the upper fan group and the lower fan group adjust the relative inclination angle of each other, the heat exchanger module and the upper fan group can also be additionally provided with a guide plate to optimize the closed flow channel. Thus, each modular heat sink assembly can achieve the best heat dissipation efficiency of the heat exchanger in the limited space height, so that each modular heat sink assembly has a heat dissipation capacity of 20kW to 40kW. When applied to the air-liquid cooling cabinet for air-assisted liquid cooling, the modular heat sink assembly can be installed in different numbers in various combinations as required, so that each modular heat sink assembly can be connected to the cooling liquid distribution unit to complete the installation, effectively reducing the development time and product cost.
