[0005] Generally speaking, the above-mentioned cooling pipelines 93 are independent of each other, and for the convenience of configuration, they all have the same pipe diameter in terms of structural design. Therefore, it is difficult to arrange many pipelines in the limited space inside the server 9, and the same pipe diameter of the cooling pipelines 93 will form the same cooling water flow rate, and it is also impossible to meet the requirements that vary according to the actual situation for different heat sources (generating different amounts of heat).

In addition, by respectively concentrating the first connectors and the second connectors for connecting the cooling pipelines of various electronic devices in the electronic equipment on the first cavity and the second cavity, the convenience of organizing the cooling pipelines can be improved.

[0039] To fully understand the purpose, features and effects of the present utility model, the following describes the preferred specific embodiments of the present utility model with reference to the accompanying drawings.
[0040] Please refer to Figure 3 , which is a perspective view of the preferred specific embodiment of the present utility model. In Figure 3 , a coolant flow distributor 1 is shown. This coolant flow distributor 1 can be used for a server 9 as shown in Figure 1 , and can adjust and distribute the change of coolant flow according to the quantity and heat generation conditions of various electronic devices in the server 9, such as the central processing unit 91 and the graphics display 92 shown in Figure 1 , thereby improving the heat dissipation effect. In addition, the coolant flow distributor 1 can gather together the cooling pipeline 93 (input pipeline 931 and output pipeline 932) as shown in Figure 2 , and thus improve the application flexibility of the server 9 in the limited internal space.
[0041] Please also refer to Figure 4 and Figure 5 , wherein Figure 4 is a sectional view of the preferred specific embodiment of the present utility model at the position of the first cavity above, Figure 5 is a sectional view of the preferred specific embodiment of the present utility model at the position of the second cavity below, and please also refer to Figure 3 simultaneously.
[0042] As shown in Figures 3 to 5 , the coolant flow distributor 1 includes a first cavity 2, a second cavity 3 and a conveying pipeline 4. Among them, the first cavity 2 has a first chamber 20, and the first chamber 20 is partitioned into two first compartments 21. In addition, the first cavity 2 is provided with a plurality of first connectors 22. Among the plurality of first connectors 22, the first quantity corresponds to one of the two first compartments 21 in communication, and the second quantity among the plurality of first connectors 22 corresponds to the other of at least two first compartments 21 in communication.
[0043] Again, as shown in Figures 3 to 5As shown, the second cavity 3 has a second chamber 30, and the second chamber 30 is partitioned into two second compartments 31. In addition, the second cavity 3 is provided with a plurality of second connectors 32, and a third quantity of the plurality of second connectors 32 corresponds to and communicates with one of the two second compartments 31, and a fourth quantity of the plurality of second connectors 32 corresponds to and communicates with the other of the two second compartments 31.
[0044] In this embodiment, the quantities of the first compartment 21 and the second compartment 31 are both two, that is, the quantity of the second compartment 31 corresponds to and is the same as the quantity of the first compartment 21. Additionally, in this embodiment, the first quantity is two, that is, two first connectors 22 correspond to and communicate with one of the two first compartments 21, and the second quantity is eight, that is, eight first connectors 22 correspond to and communicate with the other of the two first compartments 21. Similarly, the third quantity is two, that is, two second connectors 32 correspond to and communicate with one of the two second compartments 31, and the fourth quantity is eight, that is, eight second connectors 32 correspond to and communicate with the other of the two second compartments 31. That is to say, the third quantity corresponds to and is the same as the first quantity, and the fourth quantity corresponds to and is the same as the second quantity.
[0045] In this embodiment, it is taken as an example that there are two types of electronic devices, namely a central processing unit and a graphics processing unit, in the server that need to be cooled. Therefore, the above-mentioned first compartment 21 and second compartment 31 are each two. If there are more than two types of electronic devices (such as network cards, etc.) in the server that need to be cooled, the first compartment 21 and the second compartment 31 can each be three or more.
[0046] Also in this embodiment, it is taken as an example that two central processing units and eight graphics processing units need to be cooled. Therefore, the above-mentioned first quantity is two, the second quantity is eight. Similarly, the third quantity is two, and the fourth quantity is eight. However, this is only for illustration and is not limited to the aforementioned quantities.
[0047] Again, for example Figures 3 to 5 As shown, the conveying pipeline 4 has an input end 41 and an output end 42. The input end 41 communicates with the first chamber 20 of the first cavity 2 and branches into two input branch pipelines 411. That is to say, the quantity of the two input branch pipelines 411 corresponds to and is the same as the quantity of the two first compartments 21 and respectively communicates with the two first compartments 21, and the output end 42 communicates with the second chamber 30 of the second cavity 3 and branches into two output branch pipelines 421. That is to say, the quantity of the two output branch pipelines 421 corresponds to and is the same as the quantity of the two second compartments 31 and respectively communicates with the two second compartments 31. As described above, the quantities of the input branch pipelines 411 at the input end 41 and the output branch pipelines 421 at the output end 42 change according to the quantities of the first compartment 21 and the second compartment 31.
[0048] During use, the coolant (such as cooling water, not shown in the figure) in the delivery pipeline 4 enters the two first compartments 21 respectively via the two input branch pipelines 411 at the input end 41, and cools the two central processing units and eight graphics processing units respectively via the two and eight first connectors 22 corresponding to the two first compartments 21 through the input pipelines (not shown in the figure). After cooling (after heat exchange), the coolant then enters the two second compartments 31 via the two and eight second connectors 32 corresponding to the two second compartments 31 through the output pipelines (not shown in the figure), and then flows out from the output end 42 via the two output branch pipelines 421. After heat exchange outside, it is input again from the input end 41, and this cycle is used to cool the two central processing units and eight graphics processing units.
[0049] As can be seen from the above, during cooling, the two input branch pipelines 411, the two output branch pipelines 421, the two first compartments 21, and the two second compartments 31 can be used to adjust and distribute the changing coolant flow rate. That is, for electronic devices with different heat generation amounts, the coolant flow rate can be changed according to actual needs, which can greatly improve the heat dissipation efficiency.
[0050] In the above example, when the coolant enters the two first compartments 21 respectively via the two input branch pipelines 411, the coolant flow rates in the two input branch pipelines 411 will be approximately the same. When the coolant flows out via the two and eight first connectors 22, the coolant flow rate flowing out via the two first connectors 22 will be larger, while the coolant flowing out via the eight first connectors 22 will have a smaller coolant flow rate because it is relatively dispersed.
[0051] In the variable design, the second quantity and the fourth quantity of the second connectors 32 can be greater than, equal to, or less than the first quantity and the third quantity of the first connectors 22 respectively. That is to say, it can be changed according to the number of electronic devices to be cooled. Similarly, the volumes of the two first compartments 21 can be different or the same as each other, and the volumes of the two second compartments 31 can be different or the same as each other.
[0052] In addition, the above-mentioned multiple first connectors 22 can be of the quick connector type respectively, or can be of the screw thread connector type respectively. Similarly, the above-mentioned multiple second connectors 32 can be of the quick connector type respectively, or can be of the screw thread connector type respectively. That is to say, when the multiple first connectors 22 and the multiple second connectors 32 are respectively connected to the input pipelines (not shown in the figure) and the output pipelines (not shown in the figure), the connector type can be changed according to actual needs to provide convenience during connection.
[0053] Please refer to Figure 3 , in this embodiment, the first cavity 2 and the second cavity 3 are stacked on top of each other, that is, the first cavity 2 and the second cavity 3 are stacked into one body. Of course, they can also be arranged separately from each other according to actual configuration requirements.
[0054] When actually in use, various sensors (not shown in the figure) can be additionally installed to provide information to an external controller (not shown in the figure) to control the coolant flow rate in the conveying pipeline 4, such as a flow sensor, a temperature sensor, etc.

However, those skilled in the art should understand that the preferred specific embodiment is only used to describe the present utility model and should not be construed as limiting the scope of the present utility model. It should be noted that any equivalent changes and substitutions to the preferred specific embodiment should be regarded as being covered within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the content defined by the scope of the patent application.
