DETAILED DESCRIPTION

[0045] In order for those skilled in the art to better understand the technical scheme of the present application, the computing device provided by the present application is described in detail below in combination with the drawings.

[0046] The computing power module in the computing device generates a large amount of heat during operation, and therefore needs to be cooled. The air cooling method is used for cooling, but the air cooling method has low heat transfer coefficient due to air convection, which limits the cooling capacity of the air cooling method and results in poor cooling effect.

[0047] In some related technologies, the liquid cooling method is used to replace the air cooling method, which can improve the cooling effect, but the liquid cooling method has the problem of uneven cooling, which results in unsatisfactory cooling effect.

[0048] It is found through research that the liquid cooling is also more sensitive to flow resistance than the air cooling. In related technologies, the computing module in the computing device has a radiator, and the radiator is provided with a plurality of cooling fins. Since the spacing between adjacent cooling fins is small, the flow resistance is large when the fluid passes between two cooling fins. When the air cooling is used, air will flow between adjacent fins due to the large viscosity and fast flow rate of air, and heat exchange is thus achieved, so that the problem of uneven heat exchange is not obvious. However, when the liquid cooling method is used, the coolant is usually cooling oil, which has large viscosity and slow flow rate, so the coolant is more likely to flow from the place with large flow resistance to the place with small flow resistance, and the coolant will not flow between adjacent fins.

[0049] In some related technologies, since the space for placing the power module 20 and the space for placing the computing module 30 in the computing device are communicated with each other, the coolant is more likely to flow to the power module 20, and less coolant flows to the computing module, which results in poor cooling effect of the computing module 30.

[0050] To solve the above technical problems, the utility model discloses a kind of computing devices, comprising: shell assembly 10, power module 20 and computing module 30.

[0051] As shown in Figure 1 And Figure 2 The shell assembly 10 has a first coolant channel 40 and a second coolant channel 50 arranged in a first direction, the power module 20 is arranged in the first coolant channel 40, and the computing module 30 is arranged in the second coolant channel 50.

[0052] The first coolant channel 40 and the second coolant channel 50 are respectively communicated with the outside of the shell assembly 10 at both ends in the first direction, and the first coolant channel 40 and the second coolant channel 50 are isolated from each other to limit the flow of liquid coolant in the second coolant channel 50 to the first coolant channel 40.

[0053] During use, the external liquid refrigerant enters the first refrigerant channel 40 and the second refrigerant channel 50 respectively, and exchanges heat with the power module 20 and the computing module 30 respectively. Since the first refrigerant channel 40 and the second refrigerant channel 50 are isolated from each other, the refrigerant in the second refrigerant channel 50 cannot enter the first refrigerant channel 40. Therefore, it can only flow along the second refrigerant channel 50 and exchange heat with the computing module 30, ensuring that the refrigerant in the second refrigerant channel 50 fully exchanges heat with the computing module 30, thereby improving the heat exchange effect of the computing module 30.

[0054] The computing device of the present invention can prevent the refrigerant in the second refrigerant channel 50 from flowing into the first refrigerant channel 40 by isolating the first refrigerant channel 40 from the second refrigerant channel 50, so that the refrigerant in the second refrigerant channel 50 can only flow along the second refrigerant channel 50 and exchange heat with the computing module 30, ensuring that the refrigerant in the second refrigerant channel 50 fully exchanges heat with the computing module 30, thereby improving the heat exchange effect of the computing module 30.

[0055] like Figure 1 As shown, the housing assembly 10 includes: a housing 11, a partition 12, a liquid inlet plate 13, and a liquid outlet plate 14. The housing 11 has a first end and a second end along a first direction, and a through channel is provided inside the housing 11 from the first end to the second end; the partition 12 is provided in the channel along the first direction, and the two ends of the partition 12 in the first direction extend to the two ends of the housing 11, dividing the channel into a first refrigerant channel 40 and a second refrigerant channel 50 adjacent to each other in a third direction; Figure 3 As shown, in the second direction, the second refrigerant channel 50 has two first side walls 51 oppositely arranged, and the computing module 30 is connected to the first side walls 51 .

[0056] The liquid inlet plate 13 is connected to the first end of the housing 11. The liquid inlet plate 13 is provided with a first liquid inlet 131 and a second liquid inlet 132. The first liquid inlet 131 is connected to the first refrigerant channel 40, and the second liquid inlet 132 is connected to the second refrigerant channel 50.

[0057] The liquid outlet plate 14 is connected to the second end of the shell 11 . A first liquid outlet 141 and a second liquid outlet 142 are provided on the liquid outlet plate 14 . The first liquid outlet 141 is connected to the first refrigerant channel 40 , and the second liquid outlet 142 is connected to the second refrigerant channel 50 .

[0058] During use, the liquid refrigerant enters the first refrigerant channel 40 through the first liquid inlet 131 to exchange heat with the power module 20, and then is discharged from the first liquid outlet 141; the liquid refrigerant enters the second refrigerant channel 50 through the second liquid inlet 132 to exchange heat with the computing module 30, and then is discharged from the second liquid outlet 142.

[0059] It should be noted that, in this embodiment, the first direction is the x-axis direction, the second direction is the y-axis direction, and the third direction is the z-axis direction, and the first direction, the second direction, and the third direction intersect with each other.

[0060] It should also be noted that, in this embodiment, the housing assembly 10 includes: a housing 11, a partition 12, a liquid inlet plate 13, and a liquid outlet plate 14, wherein the liquid inlet plate 13 is connected to the first end of the housing 11, and the liquid outlet plate 14 is connected to the second end of the housing 11. However, this is not restrictive. In some other embodiments not shown in the figures, the housing assembly 10 may include: a housing 11, a partition 12, and a liquid inlet plate 13, wherein the liquid inlet plate 13 is connected to the first end of the housing 11. Alternatively, the housing assembly 10 may include: a housing 11, a partition 12, and a liquid outlet plate 14, wherein the liquid outlet plate 14 is connected to the second end of the housing 11. In other words, without violating the inventive concept and technical principles of the present invention, the above situations all fall within the scope of protection of the present invention.

[0061] For example, Figure 3 As shown, the housing 11 includes: a first side plate 111, a second side plate 112, a third side plate 113, and a fourth side plate 114. The first side plate 111 and the second side plate 112 are spaced apart along the second direction; the third side plate 113 and the fourth side plate 114 are spaced apart along the third direction, and the third side plate 113 and the fourth side plate 114 are connected between the first side plate 111 and the second side plate 112 to form a channel.

[0062] The partition 12 is parallel to the third side plate 113 and is connected to the first side plate 111 and the second side plate 112 respectively. A first refrigerant channel 40 is formed between the first side plate 111, the second side plate 112, the third side plate 113 and the partition 12. A second refrigerant channel 50 is formed between the first side plate 111, the second side plate 112, the fourth side plate 114 and the partition 12. Figure 3 As shown, the portion of the inner wall of the first side plate 111 and the second side plate 112 opposite to each other and located in the second refrigerant channel 50 is the first side wall 51 .

[0063] In this embodiment, the first side panel 111 and the second side panel 112 are parallel to each other, and the first side panel 111 and the second side panel 112 are both perpendicular to the second direction; the third side panel 113 and the fourth side panel 114 are parallel, and the third side panel 113 and the fourth side panel 114 are both perpendicular to the third direction, and the partition 12 is located between the second side panel 112 and the third side panel 113 and is parallel to the third side panel 113 and the fourth side panel 114.

[0064] The utility model discloses a computing device through setting first side plate 111, second side plate 112 and third side plate 113, can pass through first side plate 111, second side plate 112 and third side plate 113 and enclose the passageway along the first direction, and through connecting the baffle 12 between two first side plate 111, thereby separating the passageway into independent first refrigerant passage 40 and second refrigerant passage 50, thereby can prevent the refrigerant in second refrigerant passage 50 and flow to first refrigerant passage 40, thereby improve the heat exchange efficiency of computing module 30.

[0065] As Figure 4 The utility model discloses a computing device through setting first side plate 111, second side plate 112 and third side plate 113, can pass through first side plate 111, second side plate 112 and third side plate 113 and enclose the passageway along the first direction, and through connecting the baffle 12 between two first side plate 111, thereby separating the passageway into independent first refrigerant passage 40 and second refrigerant passage 50, thereby can prevent the refrigerant in second refrigerant passage 50 and flow to first refrigerant passage 40, thereby improve the heat exchange efficiency of computing module 30.

[0066] As Figure 5 The utility model discloses a computing device through setting first side plate 111, second side plate 112 and third side plate 113, can pass through first side plate 111, second side plate 112 and third side plate 113 and enclose the passageway along the first direction, and through connecting the baffle 12 between two first side plate 111, thereby separating the passageway into independent first refrigerant passage 40 and second refrigerant passage 50, thereby can prevent the refrigerant in second refrigerant passage 50 and flow to first refrigerant passage 40, thereby improve the heat exchange efficiency of computing module 30.

[0067] Need to explain, in the embodiment, the PCB board 31 is rectangle, but this is not restrictive, in some other embodiments not shown in the drawing, the PCB board can also be the special-shaped structure, under the premise of not violating the inventive concept and technical principle of the utility model, the above-mentioned case all belongs to the protection scope of the utility model.

[0068] The electrode sheet 33 is connected at the first end of the PCB board 31 for connection with the power module 20, as Figure 5 The utility model discloses a computing device through setting first side plate 111, second side plate 112 and third side plate 113, can pass through first side plate 111, second side plate 112 and third side plate 113 and enclose the passageway along the first direction, and through connecting the baffle 12 between two first side plate 111, thereby separating the passageway into independent first refrigerant passage 40 and second refrigerant passage 50, thereby can prevent the refrigerant in second refrigerant passage 50 and flow to first refrigerant passage 40, thereby improve the heat exchange efficiency of computing module 30.

[0069] Further, the first side wall 51 is provided with a guide portion 52, and the PCB board 31 is provided with a sliding portion 34 matched with the guide portion 52, and the first side wall 51 and the PCB board 31 are slidably matched through the guide portion 52 and the sliding portion 34.

[0070] For example, as shown in Figure 3 and Figure 4 , the guide portion 52 is a guide rail provided on the first side wall 51, and the sliding portion 34 is a guide groove provided at both ends of the PCB board 31. Among them, the guide rail and the guide groove are arranged along the first direction. In use, align the guide groove at the first end of the PCB board 31 with the guide rail on the first side plate 111 and insert the guide rail into the guide groove, align the guide groove at the second end of the PCB board 31 with the guide rail on the second side plate 112 and insert the guide rail into the guide groove, and then push the PCB board 31 along the first direction to complete the assembly of the PCB board 31 into the first refrigerant channel 40.

[0071] It should be noted that in the present embodiment, the guide portion 52 is a guide rail, and the sliding portion 34 is a guide groove, but this is not limiting, and in some other embodiments not shown in the figure, the guide portion 52 can be a guide groove, and the sliding portion 34 can be a guide rail. As long as the structure can realize the sliding fit, it is within the protection scope of the utility model.

[0072] The heat exchanger 32 is arranged on the PCB board 31 and is attached to the plurality of heat generating elements 35, and the heat generating elements 35 exchange heat with the refrigerant through the heat exchanger 32.

[0073] Further, the length of the heat exchanger 32 in the second direction is less than the length of the PCB board 31, and at least one end of the heat exchanger 32 in the second direction forms a flow space 60 with the corresponding first side wall 51.

[0074] For example, in combination with the embodiment shown in Figure 3 and Figure 4 , the heat exchanger 32 has a first end and a second end in the second direction, the first end of the heat exchanger 32 is close to the first end of the PCB board 31 and corresponds to the first side wall 51 of the first side plate 111, and the second end of the heat exchanger 32 is close to the second end of the PCB board 31 and corresponds to the first side wall 51 of the second side plate 112.

[0075] The power module 20 is arranged in the first refrigerant channel 40, and the power module 20 has a first end and a second end in the second direction, the first end of the power module 20 is close to the first side plate 111, and the second end of the power module 20 is close to the second side plate 112. The first end of the power module 20 extends to the outside of the first refrigerant channel 40 through the first mounting groove 1111. The first end of the power module 20 is provided with an electrode, and the electrode of the power module 20 is electrically connected to the electrode sheet 33 of the PCB board 31 through the copper bar.

[0076] The first side plate 111 is provided with a first mounting groove 1111 and a second mounting groove 1112, the first mounting groove 1111 is communicated with the first refrigerant channel 40, and the second mounting groove 1112 is communicated with the second refrigerant channel 50. The electrode sheet 33 extends to the outside of the first side plate 111 through the second mounting groove 1112, so as to be electrically connected with the power module 20.

[0077] As shown in Figure 4 , since the length of the heat exchanger 32 in the second direction is less than the length of the PCB plate 31 in the second direction. That is to say, the two ends of the heat exchanger 32 are not aligned with the two ends of the PCB plate 31, so when the two ends of the PCB plate 31 are connected to the two first side walls 51, in the second direction, the first end of the heat exchanger 32 and the first side wall 51 of the first side plate 111, and the second end of the heat exchanger 32 and the first side wall 51 of the second side plate 112 will form a flow space 60.

[0078] Since the gap between the flow space 60 and the fins of the heat exchanger 32 is much larger than the gap, the flow resistance is also much smaller, so the refrigerant entering the second refrigerant channel 50 will also flow to the flow space 60 with relatively small flow resistance, thereby reducing the refrigerant flowing to the fins of the heat exchanger 32, thereby affecting the heat exchange efficiency of the radiator.

[0079] In order to solve this problem, in the embodiment as shown in Figure 6 and Figure 7 , the computing device further comprises at least one blocking part 70, which is provided one-to-one with the flow space 60, and the blocking part 70 is arranged in the corresponding flow space 60 to prevent the refrigerant in the second refrigerant channel 50 from flowing to the corresponding flow space 60. The computing device of the utility model can occupy the flow space 60 by arranging the blocking part 70 in the flow space 60, so that the liquid refrigerant cannot flow to the flow space 60, but only to the fins of the heat exchanger 32, thereby improving the heat exchange efficiency of the liquid refrigerant and the heat exchanger 32.

[0080] In the embodiment as shown in Figure 6 , the blocking part 70 is a strip-shaped structure extending in the first direction, and the two ends of the blocking part 70 extend to the two ends of the first refrigerant channel 40, respectively. Preferably, the two ends of the blocking part 70 can abut on the liquid inlet plate 13 and the liquid outlet plate 14, respectively, so that the refrigerant entering the second refrigerant channel 50 can directly flow to the heat exchanger 32, avoiding the liquid refrigerant flowing to the gap between the two ends of the blocking part 70 and the liquid inlet plate 13 and the liquid outlet plate 14, respectively, thereby avoiding the generation of vortex, which is more conducive to the flow of the refrigerant and improves the heat exchange effect.

[0081] Exemplarily, the heat exchanger 32 is two, which are respectively located at two sides of the PCB board 31, and two ends of each heat exchanger 32 in the second direction form the flow space 60 with the two first side walls 51 respectively. That is, as shown in Figure 4 Exemplarily, the flow space 60 is four, as shown in Figure 6 The corresponding blocking part 70 is also four, and each blocking part 70 is located in one flow space 60. It should be noted that although in the embodiment, the heat exchanger 32 is arranged at each side of the PCB board 31, this is not restrictive, and in some other embodiments not shown in the figure, the heat exchanger 32 can be arranged at only one side of the PCB board 31.

[0082] It should also be noted that in the embodiment as shown in Figure 6 The blocking part 70 is connected with the PCB board 31. However, this is not restrictive, and the blocking part 70 can also be connected to the first side wall 51. Exemplarily, as shown in another embodiment, Figure 7 The blocking part 70 and the first side wall 51 are integrally formed. That is, the blocking part 70 is integrally formed with the first side plate 111 and the second side plate 112 respectively. In this way, the assembly steps can be simplified, and the strength of the shell 11 is increased.

[0083] It can be understood that, as shown in Figure 1 The computing module 30 is multiple, and the multiple computing modules 30 are distributed along the third direction. The flow space 60 is formed between each heat exchanger 32 and the first side wall 51, and the blocking part 70 is multiple, and each flow space 60 is provided with the blocking part 70.

[0084] As shown in Figure 8 and Figure 9 Another embodiment of the utility model also discloses a computing device, which has basically the same structure as the above-mentioned embodiments, and the difference is only that the setting position and structure of the blocking part 70 are different.

[0085] In another embodiment as shown in Figure 8 and Figure 9 The blocking part 70 is arranged between the computing module 30 and the liquid inlet plate 13 and corresponds to the position of the flow space 60. The blocking part 70 is used to block between the corresponding flow space 60 and the second liquid inlet 132, so as to prevent the liquid coolant flowing from the second liquid inlet 132 to the flow space 60.

[0086] Exemplarily as shown in Figure 8As shown, the blocking part 70 has a first surface 71 and a second surface 72, the first surface 71 is towards the corresponding flow space 60, and the first surface 71 is abutted against one side of the heat exchanger 32 towards the second liquid inlet 132; the second surface 72 is abutted against the first side wall 51 at a relatively short distance, and the blocking part 70 realizes the blocking of the corresponding flow space 60 through the first surface 71 and the second surface 72. That is, as shown in Figure 8 As shown, the first surface 71 is arranged vertically to the first direction, and the second surface 72 is arranged vertically to the second direction, and the first surface 71 is abutted against one side of the heat exchanger 32 towards the second liquid inlet 132, and the second surface 72 is abutted against the first side wall 51, which is equivalent to blocking one end of the flow space 60 for liquid, so as to effectively prevent the refrigerant from entering the flow space 60, so that the refrigerant flows more to the fins of the heat exchanger 32, and the heat exchange efficiency is improved.

[0087] In combination with Figure 3 And Figure 4 As shown, the heat exchanger 32 forms a flow space 60 between the two ends in the second direction and the corresponding first side wall 51; the blocking part 70 is two and corresponds to the two flow spaces 60 to block the corresponding flow space 60.

[0088] For example, the heat exchanger 32 has a first end and a second end in the second direction, the first end of the heat exchanger 32 corresponds to the first side wall 51 of the first side plate 111 and forms a flow space 60, and the second end of the heat exchanger 32 corresponds to the first side wall 51 of the second side plate 112 and forms a flow space 60. Two blocking parts 70 are arranged at the first end and the second end of the heat exchanger 32, respectively, and the two blocking parts 70 correspond to one flow space 60, respectively, so as to block the two flow spaces 60, prevent the refrigerant from entering the corresponding flow space 60, and thus more liquid refrigerant enters the fins of the heat exchanger 32.

[0089] It should be noted that in the embodiment, the heat exchanger 32 forms a flow space 60 between the two ends in the second direction and the corresponding first side wall 51, but this is not restrictive, and in some other embodiments not shown in the figure, one end of the heat exchanger 32 can form a flow space 60 with the corresponding first side wall, and the corresponding blocking part 70 can also be one, which also belongs to the protection scope of the utility model.

[0090] The calculation module 30 is multiple, and the multiple calculation modules 30 are distributed along the third direction; the blocking part 70 is a strip structure arranged along the third direction, the blocking part 70 corresponds to all the flow spaces 60 at the same end of all the heat exchangers 32, and the blocking part 70 is used for blocking all the corresponding flow spaces 60 to prevent the liquid refrigerant entering from the liquid inlet from flowing to any corresponding flow space 60.

[0091] Exemplarily, the computing modules 30 can be three, and the first end and the second end of the heat exchanger 32 on each computing module 30 form a flow space 60 with the corresponding first side wall 51. By setting the blocking part 70 as a strip structure and extending the blocking part 70 in the third direction, the blocking part 70 located at the first end of the heat exchanger can block all the flow spaces 60 of the first end of the heat exchanger 32, and the blocking part 70 located at the second end of the heat exchanger 32 can block all the flow spaces 60 of the second end of the heat exchanger 32, thereby preventing the refrigerant from entering any flow space 60, and facilitating assembly, simple structure of the blocking part, and convenient maintenance and replacement.

[0092] Further, the PCB board 31 is provided with the heat exchanger 32 on both sides in the third direction, each heat exchanger 32 forms a flow space 60 with the corresponding first side wall 51 at both ends in the second direction, and in the second direction, the corresponding flow spaces 60 at the same end of the two heat exchangers 32 are different in size; the blocking part 70 has a protrusion 731 corresponding to the larger one of the flow spaces 60 at the same end of the two heat exchangers 32 to block the larger flow space 60 in the second direction.

[0093] Exemplarily, as shown in Figure 4 , the heat exchanger 32 includes a first heat exchanger 321 and a second heat exchanger 322, the first heat exchanger 321 and the second heat exchanger 322 are connected on both sides of the same PCB board 31 in the third direction, the first end and the second end of the first heat exchanger 321 form a flow space 60 with the corresponding first side wall 51, and similarly, the first end and the second end of the second heat exchanger 322 form a flow space 60 with the corresponding first side wall 51. It can be seen from Figure 4 that the two ends of the first heat exchanger 321 and the two ends of the second heat exchanger 322 are staggered with each other. That is, the flow space 60 corresponding to the first end of the first heat exchanger 321 on the right side in Figure 4 is smaller than the flow space 60 corresponding to the first end of the second heat exchanger 322 on the right side in Figure 4 , and correspondingly, the flow space 60 corresponding to the second end of the first heat exchanger 321 on the left side in Figure 4 is larger than the flow space 60 corresponding to the second end of the second heat exchanger 322 on the left side in Figure 4 . Since the flow spaces 60 at the same end are different in size, if the first surface 71 is small, it cannot block the larger flow space 60, and vice versa, if the first surface 71 is large, it will block a part of the fins of the first end of the first heat exchanger 321, thereby affecting the heat exchange effect.

[0094] In the embodiment, as shown in Figure 8As shown, the blocking part 70 has a second surface 72 and a third surface 73 oppositely arranged in the second direction, and the first surface 71 is connected between the second surface 72 and the third surface 73, and the third surface 73 is provided with a protrusion 731. By arranging the protrusion 731, the area of the corresponding position of the first surface 71 can be increased. Therefore, the position of the protrusion 731 is corresponding to the larger flow space 60 of the first end of the second heat exchanger 322, and avoids the smaller flow space 60 of the first end of the first heat exchanger 321, so as to block the larger flow space 60 and avoid shielding the fins of the first end of the first heat exchanger 321, and ensure the heat exchange efficiency.

[0095] As shown in Figure 9 As shown, the second surface 72 of the blocking part 70 is also provided with an avoiding groove 721 for avoiding the guide part 52. By arranging the avoiding groove 721, the guide part 52 can be avoided, so that the second surface 72 can better fit with the first side wall 51.

[0096] It can be understood that, in the embodiment as shown in Figure 9 The blocking part 70 is connected with the first side wall 51, but this is not restrictive. In another embodiment as shown in Figure 10 The blocking part 70 can also be fixedly connected with the liquid inlet plate 13.

[0097] As shown in Figure 3 As shown, the inner wall of the first refrigerant channel 40 is provided with a protruding rib 41 arranged in the first direction, and the protruding rib 41 abuts against the outer wall of the power module 20 to form a sliding gap between the power module 20 and the inner wall of the first refrigerant channel 40. By arranging the protruding rib 41, the contact area between the outer wall of the power module 20 and the outer wall of the first refrigerant channel 40 can be reduced, and the friction can be reduced, so that the power module 20 can be better slid into or out of the first refrigerant channel 40 during assembly.

[0098] As shown in Figure 1 The shell assembly 10 further comprises a sealing cover 15 located on one side of the shell 11 in the second direction and connected with the first side plate 111. The sealing cover 15 and the first side plate 111 form a mounting cavity therebetween, and the mounting cavity is provided with a copper bar 80 and a control circuit board 90. The first side plate 111 is provided with a first mounting groove 1111 and a second mounting groove 1112. The first mounting groove 1111 is in communication with the first refrigerant channel 40, and the second mounting groove 1112 is in communication with the second refrigerant channel 50. By installing the sealing cover 15, the electrical connection area where the copper bar 80 and the control circuit board 90 are located is sealed, so that the entry of liquid refrigerant into the mounting cavity is reduced, and the heat dissipation effect of the whole machine is ensured.

[0099] It should be noted that the material of the plugging part can be polypropylene, ABS resin (acrylonitrile-styrene-butadiene copolymer, ABS is the abbreviation of Acrylonitrile Butadiene Styrene) and the like, or rubber, polyethylene foam or metal material.

[0100] It can be understood that the above embodiments are only exemplary embodiments for illustrating the principles of the present application, and the present application is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present application, and these modifications and improvements are also considered as the protection scope of the present application.
