The present invention relates to a water-cooling radiator unit and a water-cooling module using same, and more particularly to a water-cooling module, of which a pump for driving a cooling fluid to circulate is mounted in a water-cooling radiator unit instead of a water block, so that the water block can have a reduced volume while the water-cooling radiator unit enables increased cooling fluid circulating efficiency.
Various kinds of currently available electronic devices have constantly increased operating speed and upgraded performance. Following the upgraded performance of the electronic devices, electronic elements inside the electronic devices also have increased working temperature. Generally, a thermal module is a combination of a radiator or a vapor chamber and a set of heat pipes designed to cool electronic elements. Cooling fans are also used with the thermal module to enable forced heat dissipation. Such a thermal module is disposed in an electronic device to remove as much heat as possible from the electronic elements without the ability of directly moving the heat away from the electronic device. Therefore, there are manufacturers who apply a water-cooling module to the cooling of the electronic devices. The water-cooling module includes a water block and a water-cooling radiator connected to each other via tubes, so that a cooling fluid circulates between the water block and the water-cooling radiator via flow passages formed by the tubes. The water block has a heat-exchange interface, which is in direct contact with an electronic element to absorb heat produced by the electronic element. The heat absorbed by the heat-exchange interface is transferred to and carried by the cooling fluid away from the water block. The heat-carrying cooling fluid is then guided by one of the tubes to the water-cooling radiator, which is disposed outside the electronic device, and is cooled. A pump provided in or externally connected to the water block is used to drive the cooling fluid to circulate between the water block and the water-cooling radiator. In the case of an electronic device having a very limited internal space, the water block for use therewith must have dimensions strictly meeting the narrow internal space of the electronic device. However, the water block with an internally provided pump usually has a volume not small enough for use with the electronic device having a narrow internal space. Therefore, it is very important to work out a way for solving the cooling problem of an electronic device with very limited internal space.
To solve the problem in the conventional water-cooling module, a primary object of the present invention is to provide a water-cooling radiator unit having a pump mounted thereon, so that a water block without a pump and having a reduced volume can be used with the water-cooling radiator unit to form a water-cooling module.
Another object of the present invention is to provide a water-cooling module that includes a water-cooling radiator unit having a pump mounted thereon, so that the water-cooling module can have improved cooling fluid circulating efficiency and use a water block without a pump but having a reduced volume.
To achieve the above and other objects, the water-cooling radiator unit according to the present invention includes a main body and a pump.
The main body includes a first section having a first flow passage system formed thereon, a second section having a second flow passage system formed thereon, and a transit zone located between the first and the second section and fluidly communicable with the first and the second flow passage system. The first section is provided with an inlet, the second section is provided with an outlet, and the transit zone is formed with a plurality of first apertures fluidly communicable with the first flow passage system on the first section, a water-guiding opening formed on a bottom of the transit zone and fluidly communicable with the first apertures via a bottom passage, and a plurality of second apertures fluidly communicable with the second flow passage system on the second section. And, the main body is internally filled with a cooling fluid.
The pump is mounted in the transit zone and includes a plurality of blades for driving the cooling fluid filled in the main body to circulate in the main body.

Since the water-cooling radiator unit 1 included in the water-cooling module 2 is identical to that having been described with reference to
The water block 22 has an enclosure 221, which internally defines at least one water-receiving space 222 and includes a heat-exchange interface 223, a water inlet 224 and a water outlet 225. The water inlet 224 and the water outlet 225 are fluidly communicable with the water-receiving space 222; and the heat-exchange interface 223 is formed on one side of the enclosure 221 and in contact with the water-receiving space 222.
The first tube 23 has a first end 231 and a second end 232 connected to the water inlet 224 on the water block 22 and the outlet 112a on the main body 11, respectively.
The second tube 24 has a third end 241 and a fourth end 242 connected to the water outlet 225 on the water block 22 and the inlet 111a on the main body 11, respectively.
The water-cooling module 2 in the first embodiment thereof is characterized in that the pump 21 is mounted in the transit zone 113 of the water-cooling radiator unit 1 and that the water-cooling radiator unit 1 with the pump 21 mounted thereon is connected to the water block 22 via the first and the second tube 23, 24. With these arrangements, the water-cooling module 2 can provide cooling function through circulation of a cooling fluid 116 between the water-cooling radiator unit 1 and the water block 22. The water-cooling module 2 of the present invention is significantly different from prior art water-cooling modules in that the pump 21 is removed from the water block 22 to reduce an overall volume of the water block 22, enabling the water block 22 to be easily mounted in a heat-producing electronic device that has a very limited internal space. The pump 21 removed from the water block 22 is now mounted in the water-cooling radiator unit 1, which can be externally connected to the heat-producing electronic device without being limited by the narrow internal space of the electronic device. With this arrangement, the water block 22 can have a reduced volume and the pump 21 can directly drive the cooling fluid 116 in the water-cooling radiator unit 1 to circulate more efficiently to provide improved cooling effect.
In the water-cooling module 2 according to the first embodiment thereof, the water block 22 is in direct contact with a heat source (not shown) for absorbing and transferring the heat to the cooling fluid 116, the water-cooling radiator unit 1 is connected to the water block 22 via the first and second tubes 23, 24 to cool the cooling fluid 116, the heat-exchange interface 223 has an inner side facing and contacting with the water-receiving space 222 defined in the water block 22, and the cooling fluid 116 circulates in the water-receiving space 222 to carry away the heat absorbed by the heat-exchange interface 223. The water-cooling module 2 of the present invention is characterized in the structural arrangements of the water-cooling radiator unit 1. More specifically, in the water-cooling radiator unit 1, the partitioning section 114 divides the main body 11 into the first and the second section 111, 112, which serve as a water-in area and a water-out area, respectively; and the transit zone 113 is a key area for driving the cooling fluid 116 to circulate in the main body 11. The transit zone 113 is characterized in having the first apertures 1131 and the second apertures 1132 provided thereat. The second apertures 1132 are formed on the wall located between the transit zone 113 and the second reservoir 1132a, the water-guiding opening 1133 is formed on the bottom of the transit zone 113 and communicates with the first apertures 1131 via the bottom passage 1134. When the cooling fluid 116 has flowed into the first flow passage system 1111 via the inlet 111a on the water-cooling radiator unit 1, it further flows through the first longitudinal flow passages 1111b and the first transverse flow passages 1111a of the first flow passage system 1111 toward the transit zone 113. The cooling fluid 116 passes through the first apertures 1131 into the bottom passage 1134 located below the transit zone 113 and then passes through the water-guiding opening 1133 formed on the bottom of the transit zone 113 to finally enter the transit zone 113. At this point, the cooling fluid 116 is driven by the blades 211 of the pump 21 mounted in the transit zone 113 to flow through the second apertures 1132 to leave the transit zone 113 and enter into the second reservoir 1132a. The cooling fluid 116 keeps flowing through the second apertures 1132 formed on the outer wall of the second reservoir 1132a into the second flow passage system 1121. Then, the cooling fluid 116 flows through the second transverse flow passages 1121a and the second longitudinal flow passages 1121b of the second flow passage system 1121 toward the outlet 112a on the second section 112 to finally leaves the water-cooling radiator unit 1. Thereafter, the cooling fluid 116 flows back into the water block 22 via the first tube 23, which is connected to the water inlet 224 of the water block 22. At this point, the cooling fluid 116 has already been cooled and circulates in the water-receiving space 222 of the water block 22 to carry away the heat absorbed by the heat-exchange interface 223 before leaving the water-receiving space 222 of the water block 22 via the water outlet 225. The heat-carrying cooling fluid 116 then flows into the water-cooling radiator unit 1 again via the second tube 24, which is connected at the third end 241 to the water outlet 225 of the water block 22 and at the fourth end 242 to the inlet 111a provided on the main body 11 of the water-cooling radiator unit 1. The heat-carrying cooling fluid 116 is cooled again when it flows through the water-cooling radiator unit 1.
The water-cooling module 2 of the present invention is characterized in that the water block 22 has a reduced volume because the pump 21 is not provided in the water block 22 but is mounted on the water-cooling radiator unit 1 to facilitate the circulation and cooling of the cooling fluid 116 in the water-cooling radiator unit 1. With this arrangement, the water block 22 can still be used in an electronic device that has a very limited internal space to maintain good cooling and circulation of the cooling fluid 116.
A cooling fan 3 can be correspondingly connected to one side of the water-cooling radiator unit 1 to enable forced heat dissipation from the water-cooling radiator unit 1 and more efficient cooling of the cooling fluid 116 in the water-cooling radiator unit 1. Further, by providing the first and second flow passage systems 1111, 1121 in the whole water-cooling radiator unit 1 and by mounting the cooling fan 3 to one side of the water-cooling radiator unit 1 to enable forced heat dissipation, the heat carried by the cooling fluid 116 and the heat absorbed by the main body 11 of the water-cooling radiator unit 1 can be more quickly dissipated into ambient environment to cool the main body 11 and the cooling fluid 116. The cooled cooling fluid 116 can flow back into the water block 22 again to carry away the heat produced by the electronic device.
The present invention has been described with some preferred embodiments thereof and it is understood that many changes and modifications in the described embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
The present application is a Continuation of U.S. patent application Ser. No. 15/275,500, filed on Sep. 26, 2016.
