This application claims priority to China Application Serial Number 202011055008.X, filed Sep. 29, 2020, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to a water cooling device and collector thereof.
In recent years, server devices see continued growth in the demand for memory, resulting in an increase in the number of memory modules being installed on the motherboard. When cooling the memory modules via water cooling, the memory modules are at differing distance to the inlet of the water cooling device. This would cause a disparity in the amount of water passing by and making heat exchange with each memory module, resulting in a variation of temperature across the memory modules. Generally speaking, memory modules positioned farther away from the inlet may have higher temperature due to relatively poor cooling efficiency.
In view of the foregoing, one of the objects of the present disclosure is to provide a novel power supply device and conductive spring contact to resolve the aforementioned problem.
To achieve the objective stated above, in accordance with an embodiment of the present disclosure, a water cooling device includes a first collector, a second collector and a plurality of first tubes. The first collector includes a receiving chamber and a plurality of distribution chamber. The receiving chamber has an inlet for receiving a working fluid. Each of the distribution chambers includes a first wall portion and a second wall portion opposite to the first wall portion. The first wall portion has an opening communicating with the receiving chamber. The second wall portion has an outlet. Each of the first tubes is connected to the outlet of one of the distribution chambers on one end, and is connected to the second collector on another end.
In one or more embodiments of the present disclosure, a size of the opening is positively correlated with a distance from the opening to the inlet of the receiving chamber.

The first collector 110 includes a housing 111 and a cover 112. The housing 111 is configured to accommodate the working fluid. The cover 112 covers the housing 111. The housing 111 includes a receiving chamber 113 and a plurality of distribution chambers 114. The receiving chamber 113 has an inlet 113a for receiving the working fluid. The inlet 113a is where the working fluid enters the water cooling device 100. The distribution chambers 114 are arranged on a side of the receiving chamber 113 and are in communication with the receiving chamber 113. The distribution chambers 114 are configured to distribute the working fluid to a plurality of outlets 115 each corresponding to one of the distribution chambers 114, such that the working fluid flows through the outlets 115 at substantially equal flow rate or flow velocity.
Specifically, each of the distribution chambers 114 includes a first wall portion 114x and a second wall portion 114y opposite to the first wall portion. The first wall portion 114x has an opening 116 communicating with the receiving chamber 113. The second wall portion 114y has the outlet 115.
For example, the inlet 113a and the outlets 115 are located on a first side wall 111a and a second side wall 111b of the housing 111 respectively. The outlets 115 are at differing distance from the inlet 113a. In addition, a fluid connector 190 may be formed on the outer side of the inlet 113a of the first collector 110. The first collector 110 may be connected to an external circulation system (not depicted) through the fluid connector 190.
Each of the first tubes 130 is connected to the outlet 115 of one of the distribution chambers 114 on one end, and is connected to the second collector 120 on another end, so as to convey the working fluid from the first collector 110 to the second collector 120.
The distribution chambers 114 or the outlets 115 thereof differ in structures or sizes. By virtue of said difference, the working fluid can flow through the outlets 115 at substantially equal flow rate or flow velocity, such that the first tubes 130 can have substantially equal cooling efficiency. Accordingly, the water cooling device 100 can provide substantially equal cooling for the memory modules 10.
Preferably, a size of the opening 116 of the distribution chamber 114 is positively correlated with a distance from the opening 116 to the inlet 113a of the receiving chamber 113. In other words, as the distance from the distribution chamber 114 to the inlet 113 increases, the size of the opening 116 (e.g., the width, height or cross-sectional area of the opening 116) of the distribution chamber 114 increases correspondingly. In an embodiment, the first collector 110 includes a first distribution chamber 114a with a first opening 116a and a second distribution chamber 114b with a second opening 116b. A distance from the first opening 116a to the inlet 113a is less than a distance from the second opening 116b to the inlet 113a. A cross-sectional area A1 of the first opening 116a is less than a cross-sectional area A2 of the second opening 116b.
Furthermore, in practice, at least one of the distribution chambers 114 may be formed with a duct 117. The opening 116 acts as the inlet of the duct 117. The duct 117 protrudes from the first wall portion 114x towards the second wall portion 114y. In cases where the number of the distribution chamber 114 with the duct 117 is two or more than two, two of the ducts 117 have differing diameters, cross-sectional areas, lengths or inner surface roughness. As the distance from the duct 117 to the inlet 113 increases, the diameter of the duct 117 increases, the cross-sectional area of the duct 117 increases, the length of the duct 117 decreases, or the inner surface roughness of the duct 117 decreases. In some embodiments, two or more design parameters of the duct 117 (e.g., diameter, cross-sectional area, length or inner surface roughness of the duct) may be changed simultaneously.
In an embodiment, the first distribution chamber 114a has a first duct 117a and the second distribution chamber 114b has a second duct 117b. A distance from the first duct 117a to the inlet 113a is less than a distance from the second duct 117b to the inlet 113a, and a diameter D1 of the first duct 117a is less than a diameter D2 of the second duct 117b.
Aside from the designs mentioned above, the first collector 110 may further include a plurality of partitions 118. The partitions 118 extend from the first wall portion 114x and along a direction away from the second wall portion 114y. An area between any two adjacent partitions 118, or an area between the inner walls of the receiving chamber 113 and one of the partitions 118 adjacent thereto, covers at least one opening 116. Preferably, the density of the partitions 118 decreases with increasing distance from the inlet 113a to even the flow rate in said areas. In a specific embodiment, the first collector 110 includes a first partition 118a, a second partition 118b and a third partition 118c at increasing distance from the inlet 113a. A distance B1 between the first partition 118a and the second partition 118b is less than a distance B2 between the second partition 118b and the third partition 118c.
Moreover, the water cooling device 100 may include a third collector 180 and a plurality of second tubes 132 as needed. The first collector 110, the first tubes 130, the second collector 120, the second tubes 132 and the third collector 180 are arranged in sequence along a direction X. The second tubes 132 are separated from one another, and the second tubes 132 communicate with both the second collector 120 and the third collector 180. The third collector 180 has an outlet 181 for discharging the working fluid. By this arrangement, the water cooling device 100 can be utilized to cool two rows of memory modules.
The inlet 113a and the outlet 181 of the water cooling device 100 may be arranged diagonally, on the same side of the water cooling device 100, or on opposite sides of the water cooling device 100. Another fluid connector 190 may be formed on the outer side of the outlet 181, and the water cooling device 100 may form a loop through the two fluid connectors 190.
In cases where the outlet 181 of the water cooling device 100 is not at the second collector 120, the second collector 120 may have a plurality of first through-holes 121 and a plurality of second through-holes 122. The first through-holes 121 and the second through-holes 122 are located on opposite side walls 123 and 124 of the second collector 120 respectively. Each of the first through-holes 121 is connected to one of the first tubes 130, and each of the second through-holes 122 is connected to one of the second tubes 132.
The second collector 120 may be formed with one or more partitions 125 as needed. The second collector 120 has two inner walls 126 and 127 opposite to each other. Each of the partitions 125 is positioned between the two inner walls 126 and 127 and is connected between the side walls 123 and 124. The partitions 125 divide the interior of the second collector 120 into a plurality of areas. The area between any two adjacent partitions 125, or the area between either of the inner walls 126 and 127 and one of the partitions 125 adjacent thereto, covers at least one of the first through-holes 121 and at least one of the second through-holes 122. In the illustrate embodiment, each area covers a single first through-hole 121 and a single second through-hole 122.

In some embodiments, the wall portion 611x is at the bottom of the housing 611. In other words, the wall portion 611x is a bottom wall of the housing 611. In some embodiments, the distribution groove 614 is recessed into the wall portion 611x. In other words, the distribution groove 614 is depressed from the surface of the wall portion 611x. Alternatively, in some embodiments, the distribution groove includes sidewalls that protrude outward from the surface of the wall portion 611x to define the distribution groove.
The distribution grooves 614 have differing flow resistance. Specifically, the flow resistance of the distribution groove 614 increases as the distance from the outlet 615 corresponding to the distribution groove 614 to the inlet 613a increases. Consequently, the working fluid entering the first collector 610 through the inlet 613a can be evenly distributed to the outlets 615, thereby making the amount of working fluid passing through the first tubes 130 substantially equal.
In addition, in cases where the at least one distribution groove 614 is plural in number, a size of the distribution groove 614 is positively correlated with a distance from one of the outlets 615 corresponding to the distribution groove 614 to the inlet 613a. In other words, as the distance from the outlet 615 to the inlet 613a increases, the distribution groove 614 corresponding to the outlet 615 increases in size (e.g., the width, height or cross-sectional area of the distribution groove 614). For example, the first collector 610 includes a first outlet 615a, a second outlet 615b, a first distribution groove 614a extending between the inlet 613a and the first outlet 615a, and a second distribution groove 614b extending between the inlet 613a and the second outlet 615b. A distance from the first outlet 615a to the inlet 613a is less than a distance from the second outlet 615b to the inlet 613a. A width El of the first distribution groove 614a is less than a width E2 of the second distribution groove 614b.
Furthermore, the housing 611 includes a wall portion 611y, which is the top wall of the housing 611, and is opposite to the wall portion 611x. The wall portion 611y may be formed with at least one distribution groove 614z. The distribution groove 614z extends between the inlet 613a and one of the outlets 615. The housing 611 may include either the distribution groove 614 on the wall portion 611x or the distribution groove 614z on the wall portion 611y. Alternatively, the housing 611 may include both the distribution groove 614 and the distribution groove 614z.

The distribution groove 914 is preferably recessed into a wall portion 913x of the receiving chamber 913 (e.g., a top wall or a bottom wall the receiving chamber 913). Moreover, the receiving chamber 913 may include a plurality of distribution grooves 914. A size of the distribution groove 914 is positively correlated with a distance from the opening 115 corresponding to the distribution groove 914 to the inlet 913a of the receiving chamber 913. For example, when a distance from a first opening corresponding to a first distribution groove to the inlet 913a is greater than a distance from a second opening corresponding to a second distribution groove to the inlet 913a, the size of the first distribution groove is greater than that of the second distribution groove.
In addition, the distribution groove of the receiving chamber 913 may be shaped similar to the distribution groove 714 in

By this arrangement, the working fluid follows a generally U-shaped path to pass through the water cooling device 400. Specifically, the working fluid would first enter the receiving chamber 113 through the inlet 113a, and the working fluid is subsequently distributed into the first tubes 430a by the distribution chambers 114. The working fluid enters the second collector 420 after passing through the first tubes 430a. The working fluid then returns to the first collector 410 after passing through the first tubes 430b and flowing into the re-entrance chamber 440. At last, the working fluid exits the water cooling device 400 through the outlet 442.
In sum, the collector of the present disclosure utilizes distribution chambers or distribution grooves to evenly distribute the received working fluid to the outlets, thereby making the amount of working fluid passing through the tubes substantially equal.
Although the present disclosure has been described by way of the exemplary embodiments above, the present disclosure is not to be limited to those embodiments. Any person skilled in the art can make various changes and modifications without departing from the spirit and the scope of the present disclosure. Therefore, the protective scope of the present disclosure shall be the scope of the claims as attached.
