Description

[Technical Field]

[0001] The present invention relates to a liquid heat dissipation device in the field of processor heat dissipation technology, and more particularly to an immersion type liquid heat dissipation device that utilizes the cooling function of a Peltier element to improve the heat dissipation effect of a processor. [Background technology]

[0002] An example of a known liquid heat dissipation device is shown in U.S. Patent No. US20060185378A1 (Patent Document 1) and U.S. Patent No. US20130299139A1 (Patent Document 2), which comprises a liquid heat dissipation head attached to the surface of the processor, liquid heat dissipation fins for heat dissipation, and two liquid pipes connected to the liquid heat dissipation head and the liquid heat dissipation fins. A liquid pump circulates the liquid heat dissipation head and the liquid heat dissipation fins, and the working fluid passes through the liquid heat dissipation head, transporting the processor's thermal energy to the liquid heat dissipation fins for re-dissipation. This lowers the liquid temperature and then allows it to flow back into the liquid heat dissipation head, thereby dissipating heat through the circulation.

[0003] Another cooling liquid heat dissipation fin structure is disclosed in U.S. Pat. No. 1,774,192 B2 (Patent Document 3), which comprises a liquid input box, a liquid collection box, and a number of fin tubes. The liquid input box is divided into a high-temperature liquid chamber and a low-temperature liquid chamber by a partition plate. The high-temperature liquid inlet of the high-temperature liquid chamber is connected to the low-temperature liquid outlet of the low-temperature liquid chamber at the wall of the liquid input box. The high-temperature liquid inlet and the low-temperature liquid outlet are each connected to a liquid cooling head via liquid tubes. A number of fins are connected between the liquid input box and the liquid collection box, and the outside of the number of fins is connected to, for example, a fan. During operation, when the high-temperature liquid flows from the high-temperature liquid inlet to the liquid input box and the liquid collection box, and then from the liquid collection box to the liquid input box and the low-temperature liquid outlet, the fan blows air over the number of fins to cool and dissipate heat, thereby lowering the liquid temperature.

[0005] The aforementioned conventional liquid cooling fan technology for dissipating heat from a working fluid is easily affected by ambient temperature. For example, if the room temperature or the internal temperature of the housing is too high, the cooling efficiency of the liquid cooling fins will decrease, directly affecting the cooling efficiency of the liquid cooling device. Therefore, to solve the drawback that the cooling efficiency of the conventional liquid cooling fan is easily affected by ambient temperature, this is a problem that the present invention actively aims to overcome. [Means for solving the problem]

[0006] The main objective of this invention is to provide an immersion type liquid heat dissipation device, in which a first liquid box at one end of the liquid heat dissipation fin is welded to the opening of the liquid storage box, and a second liquid box at the other end of the liquid heat dissipation fin and the heat dissipation fin are immersed in the cooling liquid inside the liquid storage box. A Peltier element and heat dissipation fins are installed on the outside of the liquid storage box to cool the cooling liquid inside the liquid storage box to a lower temperature, and the heat dissipation fins of the liquid heat dissipation fins are cooled by the cooling liquid.

[0007] Another object of the present invention is to provide an immersion type liquid heat dissipation device in which the liquid heat dissipation fins are securely mounted in the liquid storage box by using a positioning rail inside the liquid storage box and a fixing frame structure on both sides of the liquid heat dissipation fins.

[0008] Another object of the present invention is to provide an immersion type liquid heat dissipation device in which the internal structure of the first liquid box provided at one end of the liquid heat dissipation fin is improved to form an insulating space, separating the high-temperature liquid chamber from the low-temperature liquid chamber, which does not transfer heat to the inside of the first liquid box. [Effects of the Invention]

[0009] (i) The present invention achieves the effect of improving the cooling efficiency of a liquid-cooled heat dissipation device installed in a processor by rapidly cooling the working fluid circulating inside the heat dissipation tube assembly using a Peltier element and a coolant, thereby preventing the liquid heat dissipation fins from being affected by the ambient temperature.

[0010] (b) According to the present invention, the liquid heat dissipating fins can be securely attached to the liquid storage box.

[0011] (c) The insulating space inside the first liquid box of the present invention prevents the high-temperature liquid flowing through the high-temperature liquid chamber from transferring heat to the low-temperature liquid chamber, preventing the cooled low-temperature liquid from being heated by the high-temperature liquid in the high-temperature liquid chamber.

[0013] As shown in Figure 1, the immersion type liquid heat dissipation device 100 of the present invention is composed of a liquid cooling head 200 and two liquid tubes 300. When applied to liquid heat dissipation devices for computers and servers, it can dissipate heat from the working fluid inside the liquid cooling head 200. Also, as shown in Figures 2 and 3, a preferred embodiment of the immersion type liquid heat dissipation device 100 of the present invention is shown. It comprises a liquid storage box 10, a Peltier element 20, heat dissipation fins 30, and liquid heat dissipation fins 40.

[0014] The liquid storage box 10 is a metal box body formed by pressing, preferably made of an aluminum alloy with excellent heat conductivity. This structure includes a side wall 11, a rear wall 12, a front opening 13, a liquid storage chamber 14 (shown in Figures 2 to 4), a liquid injection hole 15 at a predetermined location on the side wall 11 that connects to the liquid storage chamber 14, and bolts 16 that are tightened into the liquid injection hole 15. The liquid storage chamber 14 is prepared for the injection of a cooling liquid.

[0015] The Peltier element 20 is made of a semiconductor material that can convert between thermal energy and electrical energy, and is mounted on the surface of the rear wall 12 of the liquid storage box 10, with the cold surface 21 attached to the surface of the rear wall 12 of the liquid storage box 10. The rear wall 12 of the liquid storage box 10 may be provided with a groove 18, for example, and the Peltier element 20 may be inserted into the groove 18, with the cold surface 21 attached to the groove base 181 of the groove 18.

[0016] The heat dissipation fin 30 is made of a highly thermally conductive aluminum alloy and has a base 31 and a plurality of heat sinks 32. The heat dissipation fin 30 is fastened to the rear wall 12 of the liquid storage box 10 using screws or the like, and the base 31 is attached to the high-temperature side 22 of the Peltier element 20, thereby cooling the high-temperature side 22 of the Peltier element 20 and maintaining the low-temperature side 21 of the Peltier element 20 at a low temperature. The heat dissipation fin 30 may be provided with a fan 33, if necessary. The fan 33 is provided on either the left or right surface of the heat dissipation fin 30 and, when driven, blows air through the heat sink 32 of the heat dissipation fin 30 to dissipate heat.

[0017] 5 and 6, the liquid heat dissipation fin 40 includes a first liquid box 41 made of an aluminum alloy, a second liquid box 42, a heat dissipation tube 43, and a liquid pump 44 for transporting the liquid. The first liquid box 41 is divided into a high-temperature liquid chamber 411 and a low-temperature liquid chamber 412, and the box walls are connected to a high-temperature liquid inlet 413 of the high-temperature liquid chamber 411 and a cooling liquid outlet 414 of the low-temperature liquid chamber 412, respectively. The second liquid box 42 is a reflux chamber 421 with an open interior. The heat dissipation tube set 43 includes a plurality of first heat dissipation tubes 431 and a plurality of second heat dissipation tubes 432. One end of the first heat dissipation tubes 431 and one end of the second heat dissipation tubes 432 are connected to the high-temperature liquid chamber 411 and the low-temperature liquid chamber 412 of the first liquid box 41, respectively. The other ends of the first heat dissipation tube 431 and the second heat dissipation tube 432 are connected to the reflux chamber 421 of the second liquid box 42. The liquid pump 44 is a ready-made product that is directly connected to the high-temperature liquid chamber 411 or the low-temperature liquid chamber 412 of the first liquid box 41, thereby forming an integrated liquid heat dissipation fin with the liquid pump. When working fluid is injected into the liquid heat dissipation fin 40, the liquid pump 44 is driven to circulate the working fluid between the liquid heat dissipation fin 40 and the liquid heat dissipation head 200. However, the liquid pump 44 may not be installed in the first liquid box 41 of the liquid heat dissipation fin 40 of this invention, but may be installed in another position (for example, the aforementioned liquid tube 300) to circulate the working fluid between the liquid cooling head 200 and the liquid heat dissipation fin 40.

[0018] 2 and 6, when assembling this invention, the second liquid box 42 of the liquid heat dissipating fin 40 and the heat dissipation tube set 43 are inserted into the liquid storage chamber 14 through the front opening 13 of the liquid storage box 10, and the outer wall of the first liquid box 41 is sealed (for example, welded) to the front opening 13 of the liquid storage box 10. Then, coolant is poured into the liquid storage chamber 14 of the liquid storage box 10 through the liquid injection hole 15, so that the second liquid storage box 42 and the heat dissipation tube set 43 are completely immersed in the coolant in the liquid storage box 10.

[0019] 2 and 4, two rails 17 are preferably provided on each of the two inner walls of the liquid storage chamber 14 of the liquid storage box 10 of the present invention. Furthermore, a fixing frame 45 is provided on each side of the heat dissipation tube set 43. When the second liquid box 42 and the heat dissipation tube set 43 are assembled into the liquid storage box 10, each fixing frame 45 is confined between the two rails 17 inside the liquid storage box 10. This allows the longer heat dissipation tube set 43 to be stably fixed inside the liquid storage box 10 and completely immersed in the coolant inside the liquid storage box 10. This allows the longer heat dissipation tube set 43 to be stably attached inside the liquid storage box 10, preventing the heat dissipation tube set 43 from shaking and causing cracks or loosening at the welds between the first liquid box 41 and the front opening 13. In particular, the fixing frame 45 has straight plates 451 connected to both sides of the heat dissipation tube set 43 and a number of mounting protrusion plates 452 perpendicular to the straight plates 451. When installed, the fixing frame 452 is fixed between the two rails 17 inside the liquid storage box 10. Due to the structural design that provides the fitting portions 19 between the front surfaces 171 of the rails 17 and the front opening 13 of the liquid storage box 10, when assembling, the first liquid box 41 is inserted so that its end face abuts the front surface 171 of the rail, and then the first liquid box 41 and the front opening 13 are welded together, thereby achieving the effect of the first liquid box 41 being securely inserted into the front opening 13 of the liquid storage box 10.

[0020] 5 and 6, the first liquid box 41 of the liquid heat dissipation fin 40 is composed of a first box body 415 and a first box cover 416, and the second liquid box 42 is composed of a second box body 422 and a second box cover 423. The first box cover 416 and the second box cover 423 are connected to a plurality of heat dissipation tube insertion holes that connect the first box body 415 and the second box body 422, respectively. Thus, both ends of the first heat dissipation tube 431 and the second heat dissipation tube 422 are inserted into the heat dissipation tube insertion holes and welded, respectively. To prevent the thermal energy of the high-temperature liquid chamber 411 of the first liquid box 41 from being transferred to the low-temperature liquid chamber 412, the first box body 415 of this embodiment is provided with a high-temperature liquid spacer 417 and a low-temperature liquid spacer 418 that are parallel to each other, and an insulating space 419 is formed between the high-temperature liquid spacer 417 and the low-temperature liquid spacer 418. This makes it possible to prevent the high-temperature working fluid flowing in the high-temperature liquid chamber 411 from transferring heat to the low-temperature working fluid in the low-temperature liquid chamber 412 by utilizing the heat insulating space 419 .

[0021] 5 and 6, in a preferred embodiment of the heat dissipation tube set 43, a corrugated heat sink 433 is provided between the first heat dissipation tube 431 and the second heat dissipation tube 432 to improve heat dissipation efficiency. Alternatively, as shown in FIGS. 7 and 8, the heat sink 433 does not need to be provided between the first heat dissipation tube 431 and the second heat dissipation tube 432 of the heat dissipation tube set 43, and the working fluid in the first heat dissipation tube 431 and the second heat dissipation tube 432 alone can sufficiently achieve the effect of high-speed heat dissipation using only the coolant in the liquid storage box 10.

[0022] 9, in order to increase the cooling efficiency of the coolant, it is also possible to mount two or more Peltier elements 20 of the present invention, and recessed grooves 18 corresponding to the number of Peltier elements 20 are provided in the rear wall 12 of the liquid storage box 10. Furthermore, the Peltier elements 20 of the present invention are not limited to being provided on the outside of the rear wall 12 of the liquid storage box 10; as shown in FIGS. 10 and 11, one or more Peltier elements 20 can also be provided on the outside of the peripheral wall 11 of the liquid storage box 10, and the same number of recessed grooves 18 for providing the Peltier elements 20 can also be provided on the outside of the peripheral wall 11.

[0023] When the present invention is applied, by passing electricity through the thermoelectric material of the Peltier element 20, the cold surface 21 of the Peltier element 20 on the outside of the liquid storage box 10 absorbs heat, lowering the temperature of the cooling liquid inside the liquid storage box 10 to ice-cold temperature, causing the working fluid flowing through the heat dissipation tube set 43 to absorb the heat, quickly cooling the working fluid, which then flows back into the liquid cooling head 200 to cool the processor. In this invention, the temperature control of the cooling liquid inside the liquid storage box 10 depends on the current and voltage passing through the Peltier element 20, which prevents the ambient temperature from affecting the cooling efficiency of the liquid heat dissipation fins 40 and achieves the effect of improving the cooling efficiency of the immersion-type liquid heat dissipation device for processors.
