Abstract
A liquid cooling device includes a liquid block, a heat-dissipating plate, a thermal-conductive pipe, a pump and a heat sink. The liquid block, the pump, and the heat sink are connected by ducts. The pump drives a coolant to circulate among them. The thermal-conductive pipe is mounted on the heat-dissipating plate. Both ends of the thermal-conductive pipe are connected to the liquid block for the coolant to flow through. The liquid block and the heat sink are respectively mounted on the corresponding electronic devices to absorb heat using the circulating coolant. The heat sink is used to dissipate heat from another heat-generating electronic device. Therefore, one less liquid block is required, and the production cost becomes lower.
Description
- 1. Field of the Invention
- The invention relates to a liquid cooling device and, in particular, to a liquid cooling device for several electronic devices.
- 2. Description of Related Art
- As modern computers have to process very complicated processes, its internal circuit design also becomes more complicated. Various electronic devices therein produce heat during their operations. Therefore, a liquid cooling device has been introduced. The liquid cooling device includes several liquid blocks, one pump and one heat sink. The liquid blocks are filled with a coolant and directly disposed on electronic device for absorbing heat from them. The liquid blocks are in fluid communications with the pump and the heat sink via ducts. Therefore, the pump operates to make the coolant circulate in the liquid blocks. The coolant thus exchanges heat with the liquid blocks. After the coolant absorbs the heat accumulated on the heat sink, it flows back to the liquid blocks for heat exchange.
- From the above explanation, it is seen that the existing liquid block is designed for a single electronic device of a particular size. To dissipate heat generated by several electronic devices on a mother board, the liquid cooling device has to have several liquid blocks respectively disposed on the electronic devices. However, this complicates the assembly and increase the production cost. It is therefore imperative to make a further improvement in the current liquid cooling device.
- An objective of the invention is to provide a liquid cooling device for dissipating heat produced by several heat-generating electronic devices.
- The disclosed liquid cooling device includes: a liquid block, a heat-dissipating plate, a highly thermal-conductive pipe, a pump, and a heat sink. The liquid block is filled with a coolant therein and disposed on a heat-generating electronic device to absorb. The heat-dissipating plate is disposed on another heat-generating electronic device to absorb heat. The highly thermal-conductive pipe is connected with the heat-dissipating plate and in communications with the liquid block for the coolant to flow through. The highly thermal-conductive pipe has a high thermal conductivity. Therefore, it has better heat absorbing/dissipating ability. The pump is in fluid communications with the liquid block via a duct. The heat sink is in fluid communications with the pump and the liquid block via ducts.
- Using the above-mentioned technical means, the invention only needs one liquid block, along with the heat-dissipating plate and the highly thermal-conductive pipe, to dissipate heat produced by the two heat-generating electronic devices. It can simultaneously water-cool them. The invention does not only reduce the cost by using one less liquid block, but also simplifies the duct connection among the components.

FIG. 1 , a liquid cooling device in accordance with the present invention is mounted on amother board 10. Themother board 10 is mounted with several electronic devices such as asouth bridge chip 11 and anorth bridge chip 12. The liquid cooling device includes a liquid block, a heat-dissipating plate 30, a highly thermal-conductive pipe 40, apump 50 and aheat sink 60. - The liquid block is filled with a coolant and mounted on the
north bridge chip 12 to absorb heat thereof. In this embodiment, the liquid block includes abody 21 and aseparator 22. - The
body 21 is mounted on thenorth bridge chip 12 and comprises a cap being mounted on a bottom board. The cap can be integrally formed with the bottom board. Theseparator 22 is formed inside the cap to separate an inner space of the cap into twochambers 211. Further, with multiple heat-dissipating fins 212 are formed on the bottom board within the twochambers 211. The outer surface of thebody 21 is formed with four fluid inlets/outlets 213 that are in fluid communications with thecorresponding chamber 211 in pairs. - The bottom surface of the heat-
dissipating plate 30 is in contact with thesouth bridge chip 11 for absorbing heat generated by thesouth bridge chip 11. In this embodiment, the heat-dissipating plate 30 comprises abottom plate 31 and afixing plate 32. - With further reference to
FIGS. 2 to 4 , thebottom plate 31 has a bottom surface in direct contact with thesouth bridge chip 11. A top surface of thebottom plate 31 is formed with twoparallel grooves 311. Both sides of the top surface of thebottom plate 31 are provided with several heat-dissipatingfins 312. The top surface of thebottom plate 31 is formed withseveral screw holes 313 between thegrooves 31 and the heat-dissipatingfins 312. - The
fixing plate 32 is mounted on the top surface of thebottom plate 31. A bottom surface of thefixing plate 32 is formed withconcave portions 321 corresponding to thegrooves 311 of thebottom plate 31, so that an accommodating space is formed between theconcave portions 321 and thecorresponding grooves 311. Thefixing plate 32 is formed withseveral screw holes 322 corresponding to thescrew holes 313 on thebottom plate 31. Screws are then used to lock thefixing plate 32 on thebottom plate 31. - The highly thermal-
conductive pipe 40 is made of a material with a high thermal conductivity. Therefore, the thermal-conductive pipe 40 has better heat absorbing/dissipating ability. In this embodiment, the highly thermal-conductive pipe 40 has a U shape configuration with two parallel parts correspondingly mounted on thegrooves 311 of the heat-dissipating plate 30. One end of the highly thermal-conductive pipe 40 is connected with the liquid block, in fluid communications with the fluid inlet/outlet 213 of one of thechambers 211, so that the coolant thus can flow into thechamber 211. The other end of the highly thermal-conductive pipe 40 is connected with the liquid block, in fluid communications with the fluid inlet/outlet 213 of theother chamber 211, so that the coolant can flow into theother chamber 211. - The
pump 50 is connected onto the liquid block via aduct 51 with the fluid inlet/outlet 213 that is in fluid communications with one of thechambers 211, so that the coolant can flow into thechamber 211 in the liquid block. - The
heat sink 60 is connected with thepump 50 and onto the liquid block with the fluid inlet/outlet 213 in communication with theother chamber 211 via twoducts 61, respectively. Thepump 50 drives the coolant to circulate among the liquid block, the heat-dissipatingplate 30, the highly thermal-conductive pipe 40, and thepump 50, and theheat sink 60. - When the pump 20 is running, the coolant is driven to circulate in the
pump 50, theheat sink 60, the liquid block, the heat-dissipatingplate 30, the highly thermal-conductive pipe 40, andducts conductive pipe 40 absorbs heat accumulated on the liquid block and the heat-dissipatingplate 30. As the coolant absorbed with the heat flows through theheat sink 60, the heat is dissipated. The coolant then circulates back to the liquid block and the heat-dissipatingplate 30 to dissipate heat on the south and north bridge chips 11, 12. - In summary, the invention uses a heat-dissipating plate and a liquid block to concurrently absorb heat generated by several heat-generating electronic devices. The heat-dissipating fins and the highly thermal-conductive pipe on the heat-dissipating plate can further enhance the heat dissipating effect. In comparison with the conventional liquid cooling device, the invention uses one less liquid block to reduce the production cost. Moreover, it simplifies the connections among various components.
