The above object of the present invention, as well as its structural and functional features, will be described in accordance with the preferred embodiments of the drawings.

The present invention provides a water-cooling device, please refer to the first and second figures, which is an exploded and assembled perspective view of the first preferred embodiment of the present invention, and is supplemented by the third figure. The water cooling device 1 is applied to a heating element 2 (such as a central processing unit or a graphics processor; see FIG. 4), and the water cooling device 1 includes a liquid storage body 11, a pump 13, and a heat exchange element 14. The liquid storage body 11 is made of a plastic material, and the liquid storage body 11 has an inlet 111, an outlet 112, a receiving space 113, a side wall 115, a heat exchange chamber 114 and a solid covering structure. 116, the side wall 115 is formed to extend downward from the liquid storage body 11 itself, and the liquid storage body 11 and the side wall 115 jointly define the heat exchange chamber 114, and the heat exchange chamber 114 communicates with the receiving space 113. And the inlet 111 and the outlet 112, and a cooling liquid is supplied therein through the heat exchange chamber 114. The solid covering structure 116 is located above the heat exchange chamber 114. The receiving space 113 is recessed on one side of the liquid storage body 11 formed in the heat exchange chamber 114. The receiving space 113 is located at the heat. A corresponding solid cladding structure 116 is over the chamber 114 and adjacent thereto.

The inlet port 111 and the outlet port 112 are respectively disposed on two sides of the liquid storage body 11, and the heat exchange element 14 is connected to the side wall 115 of the corresponding liquid storage body 11, that is, the bottom of the side wall 115 of the liquid storage body 11. An end face of the opposite heat exchange element 14 is connected to seal the heat exchange chamber 114, and the heat exchange chamber 114 is located between the heat exchange element 14 and the liquid storage body 11. Between the side wall 115 and the heat exchange element 14, there is a gasket 143 for increasing the bonding density between the liquid storage body 11 and the heat exchange element 14 to prevent leakage of the cooling liquid in the heat exchange chamber 114. The connection manner of the heat exchange element 14 and the liquid storage body 11 is described in the manner of engagement, but is not limited thereto. In the specific implementation, a combination of welding, bonding or screw locking may be selected. Heming Chen Ming.

In addition, the heat exchange element 14 is made of a highly thermally conductive metal such as aluminum, copper or gold or silver, and has the aforementioned thermal contact surface 141, a heat exchange surface 142 and a plurality of heat dissipation fins 144. Adhering to the opposite heating element 2 (such as a central processing unit or a graphics processor) for conducting heat generated by the heating element 2 to the heat exchange surface 142, the heat exchange The face 142 is located within the heat exchange chamber 114 and the heat exchange face 142 is in contact with the cooling liquid within the heat exchange chamber 114. The heat dissipating fins 144 are disposed on the heat exchange surface 142, and the heat dissipating fins 144 are arranged at a radial interval in the preferred embodiment, but are not limited thereto. Each of the heat dissipation fins 144 has a first end 1441 and a second end 1442. The first end 1441 of each of the heat dissipation fins 144 corresponds to the pusher 134. The second end 1442 extends radially away from the push. The 134 is disposed on the heat exchange surface 142 through the heat dissipation fins 144 to effectively increase the heat exchange area. Therefore, when the thermal contact surface 141 of the heat exchange element 14 conducts heat absorbed to the heat generating component 2 to the heat exchange surface 142, the heat exchange surface 142 and the plurality of heat dissipation fins 144 are heat exchanged with the cooling liquid. The cooling liquid is carried away from the heat exchange surface 142 and the heat on the heat dissipation fins 144 and flows out from the outlet 112 of the liquid storage body 11 to achieve the heat dissipation effect.

Furthermore, the pump 13 is configured to circulate the cooling liquid. The pump 13 includes a stator 131, a rotor 133 and a pusher 134. The stator 131 is integrally formed in the liquid storage body 11, that is, While the stator 131 is injection molded together with the liquid storage body 11, the stator 131 is entirely covered in the solid cladding structure 116 of the liquid storage body 11, and the liquid storage body 11 and the stator 131 covered therein are configured as The integrated design of the liquid storage body 11 and the stator 131 of the present invention can effectively increase the structural strength of the liquid storage body 11 and achieve the effect of waterproofing the stator 131 and protecting the stator 131. The stator of the conventional water-cooling device needs to be covered by a thin outer cover, and the thin outer cover is closed on the water-cooling device because the thin structure of the thin outer cover itself is thin and the overall structural strength is not good. The tightness of the cover is not so good that it tends to cause the thin cover to fall off, and the problem that the water penetrates into the stator and causes the stator to be short-circuited.

In addition, the thickness of the stator 131 covered by the solid cladding structure 116 can be designed to be thinner, so that the overall volume can be effectively reduced, and the thickness gap between the stator 131 and the corresponding rotor 133 can be reduced (shortened) to be effectively large. Improve pump operating efficiency. When the pump 13 is operated, the heat generated by the stator 131 is transmitted to the solid cladding structure 116, so that the heat absorbed by the solid cladding structure 116 can be heat-exchanged through the cooling liquid in the heat exchange chamber 114. Thereby, the heat accumulation of the stator 131 can be avoided, and the effect of the service life of the water cooling device can be effectively improved.

Referring to FIGS. 1 and 3, the stator 131 is separated from the housing space 113 and the heat exchange chamber 114, and the stator 131 includes a silicon steel sheet set 1311 and a coil group wound around the silicon steel sheet group 1311. In the preferred embodiment, the steel sheet group 1311 is formed by stacking a plurality of silicon steel sheets, but the present invention is not limited thereto. The steel sheet group 1311 can be modified into a single steel strip and roughly It has a U shape, or any other shape. A circuit board 135 is electrically connected to the coil assembly 1312, and the circuit board 135 is wrapped in the solid cladding structure 116 of the liquid storage body 11 together with the silicon steel sheet set 1311 and the coil assembly 1312 thereon, and The steel sheet group 1311 and the coil group 1312 (ie, the stator 131) and the circuit board 135 are located outside the heat exchange chamber 114 and the receiving space 113, and are blocked by the solid covering structure 116 of the liquid storage body 11. The cooling liquid in the heat exchange chamber 114 contacts the stator 131, in short, the stator 131 is not in contact with the cooling liquid. In addition, the foregoing circuit board 135 is not limited to being disposed below the stator 131, and may be disposed adjacent to a position adjacent to the stator 131.

The rotor 133 is connected to the pusher 134. The rotor 133 and the pusher 134 are respectively disposed in the receiving space 113 and the heat exchange chamber 114. The rotor 133 and the pusher 134 are exposed to the cooling liquid, whereby the rotor 133 Corresponding to the stator 131 via the liquid storage body 11 to drive the rotor 133 to drive the pusher 134 to rotate, thereby causing the pusher 134 to disturb the cooling liquid in the heat exchange chamber 114 to flow from the inlet 111. The cooling liquid is driven by the pusher 134 toward the corresponding outlet 112. The rotor 133 has a shaft center 1331 and a magnetic member 1332. One end of the shaft center 1331 is connected to the pusher 134, and the other end is axially disposed at the bottom of the receiving space 113, and the magnetic member 1332 (such as The magnet is sleeved on the other end of the shaft 1331, and the magnetic member 1332 corresponds to the stator 131 via the solid covering structure 116 of the liquid storage body 11.

Therefore, the design of the water-cooling device 1 is such that the stator 131 is entirely covered in the solid covering structure 116 of the liquid storage body 11, so as to effectively enhance the structural strength of the liquid storage body 11 and relatively protect it. The effect of the stator 131, and further the good sealing property of the liquid storage body 11 by the solid covering structure 116, makes it possible to effectively prevent water or foreign matter such as salt spray or dust or other liquid from penetrating into the eroding stator 131.

In an alternative embodiment, the plurality of heat dissipating fins may not be required in the heat exchange element 14 to directly dissipate heat received by the heat exchange surface 142 and the cooling liquid.

Please refer to FIG. 4, which is a schematic exploded view of the second preferred embodiment of the present invention, and is supplemented by reference to Figures 1 and 3. The preferred embodiment of the present invention is mainly to connect the water-cooling device 1 of the first preferred embodiment to a heat sink 3 to form a liquid cooling system. The structure and connection relationship of the water-cooling device 1 of the present preferred embodiment and its function are substantially the same as those of the water-cooling device 1 of the first preferred embodiment, and therefore will not be described again. As shown in the figure, the heat sink 3 is remote from the liquid storage body 11, and the liquid storage body 11 is connected to the heat sink 3.

The heat sink 3 has a heat sink inlet 31, a heat sink outlet 32, a first windable tube 34 and a second windable tube 35. One end of the first windable tube 34 is connected to the opposite liquid storage body 11. The other end of the inlet 111 is connected to the radiator outlet 32. One end of the second retractable tube 35 is connected to the outlet 112 of the liquid storage body 11, and the other end is connected to the radiator inlet 31, whereby the radiator 3 through the first and second retractable tubes 34, 35 respectively connected to the inlet 111 and the outlet 112 of the liquid storage body 11, so that the pusher 134 in the heat exchange chamber 114 drives the cooling liquid in the heat exchange chamber The chamber 114 and the radiator 3 circulate and dissipate heat.

In addition, the heat sink 3 can be connected to a fan 4 to help the heat sink 3 to dissipate heat rapidly. As shown, when the thermal contact surface 141 of the heat exchange element 14 conducts heat absorbed to the heat generating component 2 to the heat exchange surface 142 of the heat exchange chamber 114 to pass through the heat exchange chamber 114 After the cooling liquid exchanges heat with the heat exchange surface 142, the cooling liquid is discharged from the outlet 112 of the liquid storage body 11 , flows into the heat sink inlet 31 through the second windable tube 35 , and is radiated through the heat sink 3 . Thereafter, the first retractable tube 34 passes from the radiator outlet 32 and then flows into the heat exchange chamber 114 from the inlet 111. The heat generating element 2 is dissipated by a cycle such as cooling the liquid.

Therefore, the design of the liquid cooling system is constructed by connecting the heat sink 3 to the water cooling device 1 of the present invention, so that a better heat dissipation effect can be effectively achieved. In addition, since the stator 131 of the water-cooling device 1 and the liquid storage body 11 are integrally formed by injection molding, the structural strength of the liquid storage body 11 is effectively increased, and the effect of the stator 131 being waterproof and protecting the stator 131 is effectively achieved.

Please refer to Figures 5 and 6, which are exploded and combined perspective views of a third preferred embodiment of the present invention. The water-cooling device 1 of the preferred embodiment is mainly designed to modify the water-cooling device 1 of the first preferred embodiment to have upper and lower chambers (ie, pump chamber 118, heat exchange chamber 114), rotor 133 and push. The stator 131 accommodated in the upper chamber (ie, the pump chamber 118) and the stator 131 covered by the solid cladding structure 16 is disposed between the upper and lower chambers in the liquid storage housing 11.

The water-cooling device 1 of the preferred embodiment includes the liquid storage body 11, the pump 13, and the heat exchange element 14. The liquid storage body 11 has an inlet 111, an outlet 112, a receiving space 113, and an upper and lower portions. a side wall 1151, a 1152, a constant hole 117, a pump chamber 118 communicating with the inlet 111, a heat exchange chamber 114 communicating with the outlet 112, and a solid cladding structure 116, wherein the upper and lower sidewalls 1151, 1152 are from The liquid storage body 11 itself is formed to extend upward and downward, respectively, and the solid covering structure 116 is integrally formed at the center of the liquid storage body 11, and the solid covering structure 116 is respectively connected to the upper side of the liquid storage housing 11. The lower sidewalls 1151, 1152 collectively define the pump chamber 118 and the heat exchange chamber 114. The through hole 117 extends through the solid cladding structure 116. The pump chamber 118 is located above the corresponding heat exchange chamber 114, and the pump chamber 118 communicates with the heat exchange chamber 114 via the through hole 117 to make the pump chamber The cooling liquid in the 118 flows into the heat exchange chamber 114 through the through hole 117.

The receiving space 113 is recessed on the side of the liquid storage body 1 in the pump chamber 118, and is located on the bottom surface of the pump chamber 118 and adjacent to each other. The structure 116 should be solidly covered, and the inlet 111 and the outlet 112 are respectively disposed on one side of the liquid storage body 11 corresponding to the pump chamber 118 and the heat exchange chamber 114. Therefore, the thickness of the stator 131 covered by the solid cladding structure 116 can be designed to be thinner, which not only provides the effect of protecting the stator 131, avoiding the contact of the cooling liquid with the stator 131, and reducing the overall volume, but also reduces (shorts) the stator 131. The thickness interval between the rotors 133 and the corresponding rotors 133 is effective to greatly increase the operating efficiency of the pump 13. In addition, when the pump 13 is operated, the heat generated by the stator 131 is transmitted to the solid cladding structure 116, so that the heat absorbed by the solid cladding structure 116 can pass through the upper pump chamber 118 or/and the lower heat exchange chamber. The cooling liquid in the chamber 114 is heat-exchanged and heat-dissipated, thereby indirectly dissipating heat to the stator 131 to avoid the effect of accumulating heat of the stator 131, thereby further improving the service life of the water-cooling device.

The structure and connection relationship of the heat exchange element 14 of the preferred embodiment and its efficiency are substantially the same as those of the heat exchange element 14 of the first preferred embodiment (ie, the included thermal contact surface 141, the heat exchange surface 142, and the plurality of heat sink fins). The sheet 144) is the same, so the same is not repeated here. The heat exchange elements 14 of the two preferred embodiments are somewhat different in that the heat exchange elements 14 of the preferred embodiment are connected to the corresponding liquid storage body 11 The side wall 1152, that is, the bottom of the lower side wall 1152 of the liquid storage body 11 is connected to one end surface of the opposite heat exchange element 14 to seal the heat exchange chamber 114, and the heat exchange surface 142 can be combined with the heat exchange chamber 114. Contact of the cooling liquid, the thermal contact surface 141 of the heat exchange element 14 is in close contact with the opposite heating element 2 (such as a central processing unit or a graphics processor; as shown in Fig. 4), and the heat exchange chamber 114 is located The heat exchange element 14 is between the solid cladding structure 116 of the liquid storage body 11. The lower side wall 1152 and the heat exchange element 14 have a gasket 143 for increasing the bonding density between the liquid storage body 11 and the heat exchange element 14 to prevent leakage of the cooling liquid in the heat exchange chamber 114. The connection manner of the heat exchange element 14 and the liquid storage body 11 is described in the manner of engagement, but is not limited thereto.

In addition, the upper side wall 1151 is connected to a top plate 119 to seal the pump chamber 118, and the top plate 119 is a separate component from the liquid storage body 1 in the present embodiment, and is combined with the liquid storage body 1 to form a liquid storage body. A part of the combination of the joints may be, for example, screwed, glued or welded or other combination that can be easily thought of and the like. The top plate 119 and the upper side wall 1151 have a further gasket 143 for increasing the bonding density between the liquid storage body 11 and the top plate 119 to prevent leakage of the cooling liquid in the pump chamber 118. The structure and connection relationship of the pump 13 of the preferred embodiment and its function are substantially the same as those of the pump 13 of the first preferred embodiment. Therefore, the pumping of the two preferred embodiments will not be repeated here. A slight difference is that the stator 131 of the pump 13 of the preferred embodiment is integrally formed in the solid cladding structure 116 of the liquid storage body 1 and is located in the pump chamber 118 and the corresponding heat exchange chamber. 114, that is, while the stator 131 is injection molded together with the liquid storage body 11, the stator 131 is entirely covered in the solid cladding structure 116 in the middle of the liquid storage body 11, so that the liquid storage body 11 and the inner portion thereof The coated stator 131 is integrally formed. Therefore, the design of the liquid storage body 11 and the stator 131 can be effectively increased, and the structural strength of the liquid storage body 11 can be effectively increased, and the stator 131 can be waterproofed and the stator 131 can be protected. Effect.

Moreover, the circuit board 135 of the stator 131 is wrapped in the solid cladding structure 116 of the liquid storage body 11 together with the silicon steel sheet set 1311 and the coil assembly 1312 thereon, and the silicon steel sheet group 1311 and the same The coil assembly 1312 (ie, the stator 131) and the circuit board 135 are located between the heat exchange chamber 114 and the pump chamber 118, and block the heat exchange chamber 114 from being separated by the solid cladding structure 116 of the liquid storage body 11. The cooling liquid in the pump chamber 118 contacts the stator 131, in short, the stator 131 is not in contact with the cooling liquid. Further, the rotor 133 and the pusher 134 of the pump 13 are respectively disposed in the accommodation space 113 and the pump chamber 118, and the rotor 133 and the pusher 134 are exposed in the cooling liquid.

Therefore, the design of the water-cooling device 1 is such that the stator 131 is entirely covered in the solid covering structure 116 of the liquid storage body 11, so as to effectively enhance the structural strength of the liquid storage body 11 and relatively protect it.
