Description

[Technical Field]

[0001] This invention relates to a heat dissipation device, and more particularly to a liquid cooling exchange system that uses water exchange for heat dissipation. [Previous Technology]

[0002] Please refer to Figure 1, which shows a conventional server cooling unit 9. This conventional server cooling unit 9 includes a server array 91, a liquid cooling exchange device 92, and a water tank 93. The liquid cooling exchange device 92 drives a coolant to flow through the server array 91, allowing the coolant to absorb the heat generated by the server array 91 during operation and then flow back to the liquid cooling exchange device 92, where it exchanges heat with the water in the water tank 93. Thus, the liquid cooling exchange device 92 drives the coolant to circulate between the server array 91 and the liquid cooling exchange device 92, and between the water tank 93 and the liquid cooling exchange device 92, thereby achieving the effect of cooling the server array 91.

[0003] In the conventional server cooling unit 9 described above, the server array 91 and the liquid cooling exchange device 92 are arranged adjacent to each other so that the liquid cooling exchange device 92 can exchange coolant for the server array 91. However, when the liquid cooling exchange device 92 is damaged, the damaged liquid cooling exchange device 92 cannot perform cooling operations on the server array 91, causing the server array 91 to stop operating, thereby affecting the working efficiency of the server array 91.

[0004] In view of this, conventional server cooling units do indeed need to be improved. [Summary of the Invention]

[0005] To solve the above problems, the purpose of this invention is to provide a liquid cooling exchange system that allows for modular replacement of the liquid cooling exchange device to maintain normal heat dissipation operation of the liquid cooling exchange system.

[0006] The directions or similar terms used throughout this invention, such as "front", "back", "left", "right", "top", "bottom", "inner", "outer", "side", etc., are mainly for reference to the directions in the accompanying drawings. Each direction or similar term is only used to help explain and understand the various embodiments of this invention and is not intended to limit this invention.

[0007] The use of the quantifiers “a” or “an” for the elements and components described throughout this invention is for convenience and to provide the general meaning of the scope of the invention; in this invention, it should be interpreted as including one or at least one, and the single concept also includes the plural case, unless it clearly means otherwise.

[0008] The terms "combination", "integration" or "assembly" used throughout this invention mainly include those that can be separated without damaging the components after connection, or those that make the components inseparable after connection. These are terms that can be selected by those with ordinary knowledge in the art based on the material of the components to be connected or the assembly requirements.

[0009] The liquid cooling exchange system of the present invention includes: a housing having a plurality of partitions that divide the housing into a plurality of liquid cooling exchange device receiving slots; and at least one liquid cooling exchange device detachably located in the liquid cooling exchange device receiving slot, the at least one liquid cooling exchange device being connected to a pipe assembly having a plurality of pipes, each pipe having a plurality of diameter segments connected from one end to the other, each diameter segment having a single diameter width, any two diameter segments having different diameter widths, the diameter segments being arranged in ascending order of diameter width, each pipe having a plurality of mating interfaces, the number of mating interfaces corresponding to the number of liquid cooling exchange device receiving slots, and each of the plurality of diameter segments having one mating interface to correspond to one liquid cooling exchange device receiving slot.

[0010] Accordingly, the liquid cooling exchange system of the present invention, through the liquid cooling exchange device housing tank detachably located in the housing by the at least one liquid cooling exchange device, allows for immediate replacement when the liquid cooling exchange device fails, or multiple liquid cooling exchange devices can be installed and switched between each other to maintain the cooling of the heat source of the server, thereby enabling the server to operate stably and perform operations with optimal computing efficiency. Furthermore, when, for example, the server is expanded, multiple liquid cooling exchange devices can be added to the liquid cooling exchange device housing tank to meet sufficient heat dissipation requirements, thereby achieving efficient heat dissipation of the server and enabling the server to have better operating efficiency. Furthermore, the at least one liquid cooling exchange device can deliver coolant through a pipe assembly. The several diameter sections can have different diameters. By gradually increasing the diameter of the pipe assembly, the liquid volume can be supplied in sequence to provide a stable liquid flow. When the at least one liquid cooling exchange device is placed in any liquid cooling exchange device receiving tank, the corresponding interface can be connected to deliver coolant.

[0011] The housing has a lower end plate, an upper end plate, and two side plates to surround and form the plurality of liquid cooling exchange device receiving tanks. In this way, the lower end plate, the upper end plate, and the side plates can prevent external dust from entering the plurality of liquid cooling exchange device receiving tanks.

[0012] The plurality of partitions are arranged sequentially and at intervals from the lower end plate to the upper end plate, so that the plurality of liquid cooling exchange device receiving slots are arranged perpendicularly side by side in the direction from the lower end plate to the upper end plate. In this way, the plurality of liquid cooling exchange device receiving slots can be vertically distributed, avoiding the effect of the liquid cooling exchange system of the present invention occupying too much lateral area.

[0013] The housing has an inlet that connects to the plurality of liquid cooling exchange device receiving tanks. This allows the at least one liquid cooling exchange device to be easily inserted into the plurality of liquid cooling exchange device receiving tanks.

[0014] The housing has a connection port that connects to the plurality of liquid cooling exchange device receiving tanks. In this way, the connection port allows the pipe assembly to be connected to at least one liquid cooling exchange device.

[0015] The housing has at least one door that can be opened and closed located at the inlet or the connection port. This facilitates the installation of at least one liquid cooling exchange device in the plurality of liquid cooling exchange device receiving tanks.

[0016] The at least one liquid cooling exchange device has a heat source output port, a heat source return port, a water source return port, and a water source receiving port. The pipe assembly is respectively connected to the heat source output port, the heat source return port, the water source return port, and the water source receiving port. In this way, the at least one liquid cooling exchange device can drive the coolant to circulate between the heat source and the liquid storage device, thereby achieving the effect of cooling the heat source.

[0017] The pipe assembly includes a heat source output pipe connected to the heat source output port of the at least one liquid cooling exchange device, a heat source return pipe connected to the heat source return port of the at least one liquid cooling exchange device, a water source return pipe connected to the water source return port of the at least one liquid cooling exchange device, and a water source receiving pipe connected to the water source receiving port of the at least one liquid cooling exchange device. Thus, the at least one liquid cooling exchange device can drive the coolant to circulate between the heat source and the liquid storage device, thereby achieving the effect of cooling the heat source.

Implementation Method

[0018] In order to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments of the present invention are described below in conjunction with the accompanying drawings; in addition, those symbols that are marked with the same symbols in different drawings are considered to be the same and their descriptions will be omitted.

[0019] Please refer to Figure 2, which is a preferred embodiment of the liquid cooling exchange system M of the present invention, which includes a housing 1 and at least one liquid cooling exchange device 2, the at least one liquid cooling exchange device 2 being detachably located in the housing 1.

[0020] The housing 1 can be formed by overlapping several frames or several plates. The housing 1 is used to install the at least one liquid cooling exchange device 2, so that the housing 1 can serve as a frame for the at least one liquid cooling exchange device 2, and the housing 1 can load the at least one liquid cooling exchange device 2. The housing 1 can be movable (e.g., with wheels) or fixed (e.g., placed in a predetermined position). The housing 1 can be located in a suitable position for connection, for example, of a server array that needs to be cooled, via pipelines. The housing 1 can have several liquid cooling exchange device receiving slots S, which can be used to house the at least one liquid cooling exchange device 2. In detail, the housing 1 may have several partitions 11, which divide the interior of the housing 1 into several liquid cooling exchange device receiving tanks S. The partitions 11 may be several baffles, so that the several liquid cooling exchange device receiving tanks S formed by the partitions 11 are not interconnected. Alternatively, the partitions 11 may be several support frames, so that the several liquid cooling exchange device receiving tanks S formed by the partitions 11 can be interconnected.

[0021] In this embodiment, the housing 1 may have a lower end plate 1a, an upper end plate 1b, and two side plates 1c to surround and form the plurality of liquid cooling exchange device receiving slots S. The plurality of partitions 11 are sequentially spaced from the lower end plate 1a toward the upper end plate 1b, so that the plurality of liquid cooling exchange device receiving slots S can be arranged perpendicularly side by side in the direction from the lower end plate 1a to the upper end plate 1b. Furthermore, the housing 1 may have an inlet 12 that connects to each of the liquid cooling exchange device receiving slots S. The housing 1 may have a connection port 13. Preferably, the connection port 13 and the inlet 12 may be located on opposite sides of the plurality of liquid cooling exchange device receiving slots S, respectively. In addition, the housing 1 may have at least one door 14 that can be opened and closed and located at the inlet 12 or the connection port 13, which can facilitate the installation of at least one liquid cooling exchange device 2 in the plurality of liquid cooling exchange device receiving slots S. Furthermore, the housing 1 may have several cooling fans or vents to help the several liquid cooling exchange device housings S dissipate heat.

[0022] The at least one liquid cooling exchange device 2 is detachably located in the plurality of liquid cooling exchange device receiving tanks S. The operator can install an appropriate number of liquid cooling exchange devices 2 according to the heat exchange requirements. The at least one liquid cooling exchange device 2 can be, for example, a cooling distribution unit (CDU), which can have a driving component such as a pump to drive the transmission of fluids such as coolant. Specifically, the at least one liquid cooling exchange device 2 can be inserted into one of the liquid cooling exchange device receiving tanks S through the inlet 12. The at least one liquid cooling exchange device 2 can be supported by the plurality of partitions 11, thereby ensuring that the at least one liquid cooling exchange device 2 is stably located in the liquid cooling exchange device receiving tank S.

[0023] Furthermore, the at least one liquid cooling exchange device 2 can be connected to a pipe assembly T, which is used to output coolant from or input coolant to the at least one liquid cooling exchange device 2. Specifically, the at least one liquid cooling exchange device 2 may have a heat source output port 21 for supplying cooling coolant to a heat source (e.g., a server array), a heat source return port 22 for receiving high-temperature coolant returning from the heat source, a water source return port 23 for returning high-temperature exchange fluid to a storage device, and a water source receiving port 24 for receiving cooled exchange fluid from the storage device. The aforementioned heat source output port 21, heat source return port 22, water source return port 23, and water source receiving port 24 are preferably connected to the connection port 13 located on the housing 1. The pipe assembly T can be connected to the heat source output port 21, heat source return port 22, water source return port 23, and water source receiving port 24 respectively through the connection port 13.

[0024] Referring to Figures 3 and 4, the pipe assembly T can connect the heat source output port 21 and the heat source return port 22 to a heat source H, such as a server array or other electronic device that generates heat. It can also connect the water source return port 23 and the water source receiving port 24 to a liquid storage device L. Thus, the at least one liquid cooling exchange device 2 can drive the coolant to flow through the heat source H, allowing the coolant to absorb the heat energy (e.g., heat energy generated by the operation of the server array) from the heat source H, and return it to the at least one liquid cooling exchange device 2. The coolant undergoes heat exchange and cooling in the liquid cooling exchange device 2, transferring the heat energy to the exchange liquid drawn from the liquid storage device L. The cooled coolant can then be reintroduced into the heat source H. Alternatively, the heat-absorbing exchange liquid can be returned to the liquid storage device L for cooling before being reintroduced into the liquid cooling exchange device 2. Thus, the at least one liquid cooling exchange device 2 can drive the liquid to circulate between the heat source H and the liquid storage device L, thereby achieving the effect of cooling the heat source H. Furthermore, since the at least one liquid cooling exchange device 2 is detachably located in the liquid cooling exchange device housing S, if the at least one liquid cooling exchange device 2 fails, the faulty liquid cooling exchange device 2 can be replaced immediately. Alternatively, when there are several liquid cooling exchange devices 2, the unfailed liquid cooling exchange devices 2 can continuously exchange coolant to maintain the cooling of the heat source H.

[0025] Please continue to refer to Figures 2 and 3. In this embodiment, the number of liquid cooling exchange devices 2 can be multiple, and the pipe assembly T can have four pipes. Furthermore, the pipe assembly T can include a heat source output pipe T1 connected to the heat source output port 21 of each liquid cooling exchange device 2, a heat source return pipe T2 connected to the heat source return port 22 of each liquid cooling exchange device 2, a water source return pipe T3 connected to the water source return port 23 of each liquid cooling exchange device 2, and a water source receiving pipe T4 connected to the water source receiving port 24 of each liquid cooling exchange device 2. Preferably, the diameter of each pipe in the above-mentioned pipe assembly T (i.e., the heat source output pipe T1, the heat source return pipe T2, the water source return pipe T3, and the water source receiving pipe T4) can gradually widen from one end to the other. Furthermore, each pipe can be formed by connecting several diameter segments from one end to the other. In this embodiment, each pipe has four diameter segments, each diameter segment can have a single diameter, and the diameters of any two diameter segments can be different.

[0026] The diameters of the plurality of diameter segments can be arranged, for example, from top to bottom in an increasing order, so that the plurality of diameter segments can be connected to form the aforementioned gradually expanding pipe fittings. The plurality of liquid cooling exchange devices 2 can be sequentially connected to positions of different diameters of each pipe fitting. More specifically, each pipe fitting can have a plurality of mating interfaces T5, the number of which can correspond to the number of liquid cooling exchange device receiving slots S. Thus, when at least one liquid cooling exchange device 2 is placed into any liquid cooling exchange device receiving slot S, the corresponding mating interface T5 can be connected. In this embodiment, when the number of liquid cooling exchange device receiving slots S is four, each pipe fitting can have four mating interfaces T5, and the four mating interfaces T5 can be located in the aforementioned four diameter segments, that is, each of the four diameter segments can have one mating interface T5, corresponding to one liquid cooling exchange device receiving slot S.

[0027] For example, the four ports T5 of the heat source output pipe T1 are respectively connected to the heat source output port 21 of each of the liquid cooling exchange devices 2. The four ports T5 of the heat source return pipe T2 are respectively connected to the heat source return port 22 of each of the liquid cooling exchange devices 2. The four ports T5 of the water source return pipe T3 are respectively connected to the water source return port 23 of each of the liquid cooling exchange devices 2. The four ports T5 of the water source receiving pipe T4 are respectively connected to the water source receiving port 24 of each of the liquid cooling exchange devices 2. In this way, when only a single liquid cooling exchange device 2 is used for operation, only a small amount of coolant needs to be driven, so a liquid cooling exchange device 2 connected to the narrow diameter position can be selected. When multiple liquid cooling exchange devices 2 are used for operation (e.g., when a server is running at full capacity and generates a large amount of heat), the amount of coolant driven will gradually increase according to the number of liquid cooling exchange devices 2 in operation. By gradually increasing the diameter of the pipe assembly T, the gradually increasing amount of liquid can be supplied to flow, thereby providing a stable liquid flow.

[0028] In summary, the liquid cooling exchange system of the present invention, through the liquid cooling exchange device housing tank detachably located in the housing by at least one liquid cooling exchange device, allows for immediate replacement when the liquid cooling exchange device fails, or multiple liquid cooling exchange devices can be installed and switched between each other to maintain the cooling of the heat source of the server, thereby enabling the server to operate stably and perform operations with optimal computing efficiency. Furthermore, when, for example, the server is expanded, multiple liquid cooling exchange devices can be added to the liquid cooling exchange device housing tank to meet sufficient heat dissipation requirements, thereby achieving efficient heat dissipation of the server and enabling the server to have better operating efficiency.
