Abstract
A liquid cooling device has a main liquid block, a pump, a heat sink, and at least one auxiliary liquid block that are in fluid communications. The auxiliary liquid block has a body and a partition that separates the body into a reservoir and a heat-absorbing chamber. The reservoir and the heat-absorbing chamber communicate with and other via a through hole on the partition. Since the heat-absorbing chamber is mounted to be adjacent to an electronic component that generates heat, the fluid in the heat-absorbing chamber absorbs the heat. When the fluid in the heat-absorbing chamber vaporizes and decreases the fluid in the reservoir has a higher level and thus flows to the heat-absorbing chamber via the through hole. Therefore, the heat-dissipating ability of the liquid cooling device is increased.
Description
- 1. Field of the Invention
- The invention relates to a liquid cooling device and, in particular, to a liquid cooling device with a longer heat-dissipating ability.
- 2. Description of Related Art
- In usual computer operations, the central processing unit (CPU) often has the highest working temperature. To efficiently reduce its temperature, a modern approach is to dispose a liquid cooling device on the CPU. The heat-dissipating device absorbs heat generated by the CPU and dissipates it.
- The above-mentioned liquid cooling device mainly includes a liquid block, a pump, and a heat sink. The liquid block is filled with a coolant and mounted on the CPU to directly absorb heat generated by the CPU. The liquid block is further in fluid communications with the pump and the heat sink via tubing. Therefore, the coolant is driven by the pump to circulate between the heat sink and the liquid block. The coolant exchanges heat with the liquid block when the coolant flows through the liquid block. After the coolant dissipates the heat when it flows through the heat sink, the coolant circulates back to the liquid block for heat exchange again.
- However, the coolant absorbing the heat may vaporize and reduce the circulating amount. This will reduce the overall heat-dissipating efficiency.
- An objective of the invention is to provide a liquid cooling device that has more coolant in order to elongate the heat-dissipating time.
- To achieve the above-mentioned objective, the disclosed liquid cooling device includes: a main liquid block, a pump, a heat sink, and at least one auxiliary liquid block. The main liquid block is filled with a coolant and disposed on a heat-generating electronic device for absorbing its heat. The pump is disposed on the main liquid block and in fluid communications with the main liquid block. The heat sink is in fluid communications with the pump via a tubing. Each auxiliary liquid block is filled with the coolant therein and includes a body and a partition. One side surface of the body is in contact with a heat-generating electronic device for absorbing its heat. The body has a reservoir and a heat-absorbing chamber. The heat-absorbing chamber is adjacent to the heat-generating electronic device. The partition is disposed inside the body between the reservoir and the heat-absorbing chamber and formed with at least one through hole connecting the reservoir and the heat-absorbing chamber. The outer wall of the body is formed with a fluid inlet and a fluid outlet that are respectively in fluid communications with the reservoir and the heat-absorbing chamber, and the main liquid block and the heat sink via tubing.
- Using the above-mentioned technical features, the reservoir can hold more coolant. When the coolant inside the heat-absorbing chamber of the auxiliary liquid block absorbs heat and vaporizes, the coolant in the reservoir will replenish it via the through hole between the reservoir and the heat-absorbing chamber. This can effectively elongate the heat-dissipating effect of the liquid cooling device.

FIGS. 1 and 2 , a first embodiment of the liquid cooling device is used to dissipate heat generated by electronic components, such aspower transistors 2 andchipsets 3, on avertical mother board 1. In this embodiment, themother board 1 has two groups ofpower transistors 2 and achipset 3. - The liquid cooling device includes a

With further reference toFIGS. 9 and 10 , in this embodiment, thesink 40 includes a heat-dissipating assembly 41 and twocontainers dissipating assembly 41 has several heat-dissipating blades 411 andmultiple fluid passages 412 that communicate between the twocontainers blade 411 can abut between twoadjacent fluid passages 412. - The two
containers dissipating assembly 41, respectively. Thefluid passages 412 communicates with the twocontainers containers 43 is connected with thepump 30 via atubing 50. Theother container 42 can be connected to theauxiliary liquid block 10 via a tubing. - With reference to
FIGS. 1 to 3 , the above-mentioned firstauxiliary liquid block 10 includes abody 11 and apartition 12. - The
body 11 is mounted on one group of thepower transistors 2. Thebody 11 is hollow and is separated into areservoir 111 and a heat-absorbingchamber 112 by thepartition 12. The bottom surface of thebody 11 is defined with afluid outlet 113 and afluid inlet 114 that respectively communicate thereservoir 111 and the heat-absorbingchamber 112. The heat-absorbingchamber 112 is adjacent to thepower transistor 2 when the firstauxiliary liquid block 10 is mounted on themother board 1. In the heat-absorbingchamber 112,multiple fins 115 are formed. Preferably, thefins 115 can protrude one side surface of the heat-absorbingchamber 112 that is adjacent to thepower transistors 2 to absorb heat generated by thepower transistors 2. The coolant exchanges heat with thefins 115. The heat exchange effect is enhanced because the coolant has a wider contact surface with thefins 115. Thefluid outlet 113 is in fluid communications with one of thecontainers 42 via thetubing 50. Thefluid inlet 114 is in fluid communications with the heat-absorbingchamber 112. - The
partition 12 is disposed in thebody 11 at the boundary between thereservoir 111 and the heat-absorbingchamber 112. Thepartition 12 is formed with two throughholes 121 so that thereservoir 111 and the heat-absorbingchamber 112 are in fluid communications. The two throughholes 121 are adjacent to an inner bottom surface of thebody 11. - The structure of the second
auxiliary liquid block 20 is basically the same as the firstauxiliary liquid block 10. The secondauxiliary liquid block 20 with one side surface contacts the other group of thepower transistors 2. Thefluid outlet 213 is in fluid communications with thefluid inlet 114 of the firstauxiliary liquid block 10 via a tubing. Thefluid outlet 214 is in fluid communications with the mainliquid block 60 via atubing 50. Therefore, when thepump 30 operates, the coolant circulates among thepump 30, theheat sink 40, the first and second auxiliary liquid blocks 10, 20, and the mainliquid block 60. The coolant flowing through the first and second auxiliary liquid blocks 10, 20 exchanges heat with thefins 115, and absorbs heat generated by thechipset 3 when it flows through the mainliquid block 60. After the coolant dissipates the absorbed heat to theheat sink 40, the coolant flows back into the first and second auxiliary liquid blocks 10, 20 and the mainliquid block 60 for further heat exchange. - With further reference to
FIG. 4 , when the coolant circulates normally in the firstauxiliary liquid block 10, the coolant fills up theentire reservoir 111 and the heat-absorbingchamber 112. With further reference toFIG. 5 , when the coolant vaporizes as it absorbs heat, the coolant level in the heat-absorbingchamber 112 drops. Since thereservoir 111 and the heat-absorbingchamber 112 are in fluid communications via the throughholes 121 on thepartition 12 and the coolant surface in thereservoir 111 is higher, the coolant flows to the heat-absorbingchamber 112 via the through holes. Thus, thereservoir 111 can increase the overall storage capacity of the coolant of the wholeliquid block 10 and timely replenish the heat-dissipatingchamber 112 when some of the coolant in the heat-dissipatingchamber 112 vaporizes, thus elongating the heat-dissipating ability of the firstauxiliary liquid block 10. The same principle applies to the secondauxiliary liquid block 20 as well. - Please refer to
FIGS. 6 , 7, and 8. The second embodiment of the invention is similar to the first embodiment. The difference is in that there is only oneauxiliary liquid block 20′ and onemain liquid block 60 in the second embodiment because there is only one group of thepower transistors 2 and onechipset 3. Thefluid outlet 213′ of theauxiliary liquid block 20′ is in fluid communications with one of thecontainers 42 of theheat sink 40 via atubing 50, it's thefluid inlet 214′ is in fluid communications with the mainliquid block 60 via thetubing 50. - Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only.
