[0093] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0094] Figure 1 is a schematic diagram of a liquid dispensing module according to an embodiment of the present invention. Figure 2A yes Figure 1 A partial enlarged view of the liquid distribution module from another perspective. Figure 2B yes Figure 1 Schematic diagram of the liquid drive unit. In order to clearly show the interior of the liquid distribution module, Figure 2A The upper cover 111 is hidden. Please refer to Figures 1 to 2B The liquid distribution module 10 of this embodiment is, for example, a coolant distribution unit (CDU) of a liquid-cooled cooling system, which can be connected to a circulation flow path to adjust and distribute the flow of coolant to achieve an effective heat dissipation effect, but the application scope of the liquid distribution module 10 is not limited to this.

[0095] The liquid dispensing module 10 includes a housing 110, a first connecting portion 160 ( Figure 2A ), at least one liquid drive unit 120 and at least one handle assembly 130. The housing 110 includes an upper cover 111, a bottom 112 and a plurality of side panels 113, and the first connection portion 160 is disposed in the housing 110. The liquid drive unit 120 is suitable for being disposed in the housing 110 and is located between the upper cover 111 and the bottom 112, and includes a second connection portion 122 ( Figure 2A The handle assembly 130 includes a connecting member 140 and a gripping member 150. The connecting member 140 is pivotally connected to the liquid driving unit 120.

[0096] In this embodiment, the at least one liquid drive unit 120 includes two liquid drive units 120. The at least one handle assembly 130 includes two handle assemblies 130, and the two handle assemblies 130 are respectively pivotally connected to the two liquid drive units 120. When one of the two liquid drive units 120 fails, the other one as a backup can be started in time, and the failed liquid drive unit 120 can be quickly replaced through the design described later without stopping the cooling system for maintenance.

[0097] Figure 3 yes Figure 1 A partial enlarged view of the liquid distribution module in a free state. Figure 4A yes Figure 1 A partial cross-sectional view of the liquid distribution module in a free state along line AA. Figure 4B yes Figure 1 A partial cross-sectional view of the liquid distribution module along line AA in another free state. Figure 4C yes Figure 1 A partial cross-sectional view of the liquid distribution module along line AA in a fixed state.

[0098] It should be noted that Figure 4A The free state S1 of the liquid driving unit 120 corresponds to Figure 3 The state of the liquid drive unit 120, while Figure 4C The fixed state S2 of the liquid drive unit 120 corresponds to Figure 1 and Figure 2A In order to clearly present the liquid drive unit 120, Figure 3The liquid drive unit 120 on the left side is hidden, and FIG. 4A to FIG. 4C Only one liquid drive unit 120 is shown and the side panels 113 are hidden.

[0099] Please refer to Figure 3 , Figure 4A and Figure 4C The holding member 150 of this embodiment is pivotally connected to the connecting member 140 and is suitable for receiving force to drive the liquid driving unit 120 to switch between the free state S1 and the fixed state S2 ( Figure 4C ). When the liquid drive unit 120 fails and needs to be replaced, for example, the liquid drive unit 120 can be switched to the free state S1, and the handle assembly 130 is suitable for driving the liquid drive unit 120 to slide along the sliding direction (i.e., the Y direction) relative to the housing 110, so that the user can easily replace the liquid drive unit 120, thereby replacing and repairing the liquid drive unit 120 in time.

[0100] Please refer to Figure 2A and Figure 4C When the liquid driving unit 120 is disposed in the housing 110, the liquid driving unit 120 can be converted into a fixed state S2 ( Figure 4C ) and fixed in the housing 110 so that the second connection portion 122 is docked with the first connection portion 160.

[0101] The first connection portion 160 of the present embodiment includes at least two first connection ends 161a, 161b, such as the liquid outlet and liquid inlet of the circulating flow path in the cooling system. The second connection portion 122 includes two second connection ends 123a, 123b, such as the liquid inlet that allows the coolant to enter and the liquid outlet that allows the coolant to flow out. When the liquid drive unit 120 is in the fixed state S2, the two second connection ends 123a, 123b are respectively connected to the at least two first connection ends 161a, 161b, and the coolant in the cooling system can enter and exit the liquid drive unit 120, and the liquid drive unit 120 can operate normally.

[0102] The following will further explain how to replace the liquid dispensing module 10. FIG. 4A to FIG. 4C The connecting member 140 of this embodiment includes a first end E1 and a second end E2 opposite to each other. The gripping member 150 includes a third end E3 and a fourth end E4 opposite to each other. The fourth end E4 is, for example, a handle for the user to grip and apply force. The bottom 112 of the housing 110 is provided with a force-bearing portion 114, which extends toward the connecting member 140 (that is, in the Z direction) and has a convex portion 116.

[0103] The first end E1 is pivotally connected to the third end E3 of the gripping member 150. The second end E2 has a hook portion 142, and the hook portion 142 corresponds to the force-bearing portion 114 of the housing 110. In addition, the liquid drive unit 120 further includes a front panel 124. The connecting member 140 is pivotally connected to the front panel 124 of the liquid drive unit 120 via a pivot axis AX, and the pivot axis AX is close to the second end E2 and away from the first end E1.

[0104] First, if Figure 4A As shown, when the liquid driving unit 120 is in the free state S1, the user can apply force to the fourth end E4 of the gripping member 150 to make the connecting member 140 connected to the gripping member 150 rotate around the pivot axis AX as the rotation center (that is, along the Figure 4A counterclockwise direction), so that the second end E2 abuts against the surface M of the front side panel 124.

[0105] In this way, it is convenient for the user to apply force to pull the liquid drive unit 120 out of the housing 110 or push it into the housing 110 along the sliding direction (Y direction). At the same time, since the handle assembly 130 of this embodiment includes the gripping member 150, the overall force arm is increased, and the liquid drive unit 120 can be pushed or pulled with less force, thereby reducing the burden on the force applyer.

[0106] Next, if Figure 4B As shown, when the liquid drive unit 120 is in the free state S1' and at least a part of the liquid drive unit 120 enters the housing 110, due to the resistance of the first connection part 160 itself and the water pressure of the circulation flow path, the user may not be able to easily push the liquid drive unit 120 completely into the housing 110. At this time, the user can continue to apply force to make the grip 150 drive the connection member 140 to rotate around the pivot AX as the rotation center (that is, along the Figure 4B In the clockwise direction), the hook portion 142 can leave the surface M and abut against the convex portion 116 of the force-bearing portion 114.

[0107] After the hook portion 142 abuts against the convex portion 116, the user can apply force in the sliding direction, and the gripping member 150 is suitable for driving the connecting member 140 to further rotate, so that the second end E2 slides relative to the force-bearing portion 114 toward the bottom 112 of the housing 110, so as to completely push the liquid driving unit 120 into the housing 110, thereby achieving the following effect. Figure 4C The fixed state S2 is shown.

[0108] Through the above design, the user only needs to apply a force of 14.3 kg to the gripping member 150 to overcome the force from the first connecting portion 160 ( Figure 2A ) For example, the resistance reaches 93.9 kg, which makes the process of assembling the liquid drive unit 120 to the housing 110 quite labor-saving, reducing the burden on the user.

[0109] In addition, when the liquid driving unit 120 is in the free state S1, the second end E2 of the connecting member 140 abuts against the surface M of the front panel 124, and does not overlap with the force-bearing portion 114 in the sliding direction (Y direction). In other words, the force-bearing portion 114 is not on the moving path of the second end E2, so the sliding process remains smooth, and the second end E2 and the hook portion 142 will not collide with the force-bearing portion 114 and cause damage.

[0110] The locking design of the liquid driving unit 120 when it is in the fixed state S2 will be specifically described below. Figure 5 yes Figure 2B Schematic diagram of the liquid drive unit from another perspective. Fig. 6A yes Figure 5 A partial enlarged view of the connecting piece, gripping piece, thumb screw and knob assembly from another perspective. Figure 6B yes Figure 5 In order to clearly show the interior of the liquid drive unit 120, Figure 6B The cover 128 is hidden.

[0111] Please refer to Figure 5 , Figure 6B and Figure 3 The front panel 124 of this embodiment has a front surface FF and a rear surface RF opposite to each other. The front surface FF is provided with a receiving groove 126 ( Figure 3 The liquid dispensing module 10 further includes two springs 180, which are respectively disposed on both sides of the rear surface RF of the front panel 124 and exposed from openings O on both sides of the rear surface RF, wherein the openings O are connected to the accommodating groove 126 ( Figure 3 ).

[0112] The spring piece 180 has a fixed section 184, an elastic section 182 and a stopper 186 ( Figure 6B The fixing section 184 is connected to the elastic section 182 and fixed to the rear surface RF. The stopper 186 is disposed on the elastic section 182. The elastic section 182 has elastic force.

[0113] like Figure 5 and Fig. 6A As shown, the connecting member 140 includes two snap-fit ​​grooves 144 ( Fig. 6A ), the two buckling grooves 144 are respectively located on opposite sides of the connecting member 140 and correspond to the two springs 180. When the liquid driving unit 120 is completely pushed into the housing 110, the connecting member 140 can be received in the receiving groove 126 ( Figure 3 ), at this time, the two locking grooves 144 are respectively locked with the two spring pieces 180 to fix the liquid driving unit 120 to the housing 110.

[0114] For details, please refer to Figures 5 to 6BWhen the connecting member 140 enters the receiving groove 126, the connecting member 140 pushes against the stopper 186 of the spring 180 ( Figure 6B ) is retracted inwardly along the X direction, so that the snap-fitting groove 144 ( Fig. 6A ) can smoothly enter the receiving groove 126. At this time, the locking groove 144 is aligned with the stopper 186 of the spring piece 180, and the stopper 186 is in the elastic section 182 ( Figure 6B ) is reset under the action of the elastic force and snaps into the snap-fitting groove 144.

[0115] In this way, the liquid drive unit 120 can smoothly switch from the free state S1 to the fixed state S2. At this time, the stopper 186 stops the connecting member 140 in the sliding direction (Y direction), which can prevent the connecting member 140 from being resisted by the first connecting portion 160 and withdrawing from the accommodating groove 126. That is, after the buckling groove 144 is buckled with the stopper 186 of the elastic section 182, the connecting member 140 can be fixed in the state as shown in FIG. Figure 4C The liquid drive unit 120 is prevented from exiting the housing 110 by moving the liquid drive unit 120 to the position shown without rotating.

[0116] In addition, if Figure 5 As shown, the liquid dispensing module 10 further includes at least one hand screw 170 (two are shown). The hand screw 170 is disposed on the connecting member 140. When the connecting member 140 is received in the receiving groove 126, that is, when the liquid drive unit 120 is in the fixed state S2, the connecting member 140 is suitable for being locked to the front panel 124 through the hand screw 170, so that the liquid drive unit 120 is more firmly fixed to the housing 110.

[0117] When the liquid driving unit 120 needs to be replaced, the user only needs to loosen the thumb screw 170 first, and then pull the gripping member 150 along the sliding direction (Y direction), and the gripping member 150 can drive the connecting member 140 to push against the stopper 186 of the spring 180 ( Figure 6B ) moves along the negative X-direction, thereby causing the locking groove 144 to disengage from the stopping portion 186 of the elastic section 182.

[0118] Once the locking groove 144 is separated from the elastic section 182, the liquid driving unit 120 is converted from the fixed state S2 to the free state S1, and the connecting member 140 can be Figure 4A or Figure 4B As shown, the liquid drive unit 120 is rotated again with the pivot axis AX as the rotation center, so that the liquid drive unit 120 slides relative to the housing 110. Through the above design, the user can quickly replace the liquid drive unit 120, the process is simple and labor-saving, and the effect of timely maintenance of the liquid drive unit 120 is achieved.

[0119] Next, the manner in which the holding member 150 is pivotally connected to the connecting member 140 will be described. Figure 7 yes Figure 1Exploded view of the connector, grip, thumb screw and knob assembly. Figure 8 yes Figure 1 A partial enlarged view of the connecting piece and the holding piece from another perspective. Fig. 9A yes Figure 1 A partial cross-sectional view of the liquid distribution module along line BB.

[0120] Fig. 9B yes Fig. 9A A partial cross-sectional view along line BB when the pressing member is pressed. Fig.10 Show Figure 1 The connector, grip and knob assembly are switched to different states. Fig.10 The rotated grip 150 is shown in dotted lines.

[0121] Please refer to Figure 7 and Figure 8 In this embodiment, the connecting member 140 has at least one recess 148 (two are shown), and the gripping member 150 has a groove 152 corresponding to the recess 148. The handle assembly 130 also includes at least one knob assembly 190 (two are shown). The knob assembly 190 is disposed in the recess 148, and the gripping member 150 is pivotally connected to the connecting member 140 through the knob assembly 190.

[0122] Please refer to Fig. 9A and Fig. 9B Specifically, the knob assembly 190 includes a pressing member 192, a positioning member 194, and an elastic member 196, and the positioning member 194 includes a positioning body 1941 and a positioning protrusion 1942. The pressing member 192 protrudes from the connecting member 140 and is connected to the positioning body 1941. The positioning body 1941 has a positioning protrusion 1942 at one end away from the pressing member 192. The elastic member 196 is disposed in the recess 148 and is located between the pressing member 192 and the positioning protrusion 1942.

[0123] Furthermore, the gripping member 150 has a first positioning groove H1, and the first positioning groove H1 is located in the groove 152. The connecting member 140 has a second positioning groove H2, and the second positioning groove H2 is located in the recess 148. The second positioning groove H2 is located opposite to the first positioning groove H1. Fig. 9A As shown, the positioning protrusion 1942 is positioned in the first positioning groove H1 and the second positioning groove H2 , so the first positioning groove H1 cannot rotate relative to the second positioning groove H2 , that is, the holding member 150 cannot rotate relative to the connecting member 140 .

[0124] like Fig. 9BAs shown, the pressing member 192 is adapted to be pressed to resist the elastic force of the elastic member 196, thereby pushing the positioning protrusion 1942 of the positioning member 194 to disengage from the second positioning groove H2 and the first positioning groove H1 and enter the groove 152. At this time, the elastic member 196 is compressed to accumulate elastic potential energy.

[0125] Next, the holding member 150 is adapted to rotate relative to the connecting member 140 with the positioning member 194 as the rotation axis, so that the positioning protrusion 1942 is misaligned in the first positioning groove H1 and is stopped by the wall surface W of the holding member 150. Fig.10 When the connecting member 140 is rotated to a predetermined angle θ (e.g., the position of the gripping member 150 shown by the dotted line), the positioning protrusion 1942 is again aligned with the first positioning groove H1. At this time, the elastic member 196 is no longer compressed and releases elastic potential energy, thereby pushing the positioning body 1941 to move in a direction away from the recess H2 (i.e., the X direction). Therefore, the positioning protrusion 1942 can be retracted into the first positioning groove H1 and the second positioning groove H2 ( Fig. 9B ) so that the holding member 150 is as Fig. 9A It is shown being fixed to the connecting member 140 again.

[0126] The gripping member 150 of this embodiment can be pivoted relative to the connecting member 140 through the knob assembly 190, which is helpful for storage and space saving. After the gripping member 150 is rotated to the predetermined angle θ, the gripping member 150 is automatically fixed to the connecting member 140, which can prevent the gripping member 150 from swinging accidentally. In addition, the predetermined angle θ of this embodiment is, for example, 90 degrees, but the predetermined angle θ is not limited thereto and can be determined according to actual design requirements.

[0127] Fig.11 yes Figure 1 A partial side view of the connector, grip and knob assembly. Fig.11 and Figure 8 In this embodiment, the first positioning groove H1 and the second positioning groove H2 are, for example, cross-shaped or approximately cross-shaped. The overall shape of the positioning body 1941 and the positioning protrusion 1942 corresponds to the shape of the first positioning groove H1 and the shape of the second positioning groove H2, so that the positioning member 194 is well positioned in the first positioning groove H1 and the second positioning groove H2, but the shape of the first positioning groove H1 and the shape of the second positioning groove H2 are not limited thereto.

[0128] Based on the above, in the liquid dispensing module of the present invention, the handle assembly includes a connecting piece and a gripping piece. The connecting piece is pivotally connected to the liquid drive unit, and the gripping piece is pivotally connected to the connecting piece, and the gripping piece is suitable for receiving force to drive the liquid drive unit to switch between a free state and a fixed state. When the liquid drive unit is in a free state, the liquid drive unit can slide relative to the shell, and the user can easily replace the liquid drive unit, thereby achieving the effect of timely replacement and maintenance of the liquid drive unit. When the liquid drive unit is in a fixed state, the liquid drive unit is fixed in the shell, and the second connecting part is connected to the first connecting part. At this time, the coolant can enter and exit the liquid drive unit for the normal operation of the liquid dispensing module. In addition, the gripping piece of the handle assembly increases the force arm, so that the user can push or pull the liquid drive unit with less force, making the process of replacing or assembling the liquid drive unit quite labor-saving.

[0129] In addition, the liquid dispensing module can also ensure that the liquid drive unit is firmly fixed in the housing when in a fixed state through the configuration of the spring sheet, the snap-fitting groove and the hand screw, and will not accidentally exit the housing due to the resistance of the first connecting part. In addition, the liquid dispensing module also includes a knob assembly, and the gripping member can be pivoted and fixed relative to the connecting member 140 through the knob assembly, which is helpful for storage and space saving.

[0130] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
