Description

Technical Field

[0001] This utility model relates to a heat exchange device, and more particularly to a gas-liquid heat exchange device. Background Technology

[0002] A heat sink is a device that removes heat from high-temperature equipment through heat conduction to reduce the equipment's temperature. Computers are devices that generate high temperatures, and water-cooled heat sinks have higher heat dissipation efficiency compared to general air cooling or passive cooling.

[0003] Please see Figure 1 The common single-layer water-cooled heat sink 1 includes a water pump module 11, two liquid hoses 12, a gas-liquid heat dissipation module 13, and several fan modules 14. The water pump module 11 is connected to the computer and drives the liquid flow to deliver heat to the gas-liquid heat dissipation module 13. The several fan modules 14 generate airflow to remove the heat from the gas-liquid heat dissipation module 13, thereby cooling the liquid.

[0004] Please see Figure 2 The gas-liquid heat dissipation module 13 has a liquid inlet 131, a liquid outlet 132, a heat dissipation structure 133, a first heat dissipation area 134, a second heat dissipation area 135, and a conductive end 136. The heat dissipation structure 133 is rectangular in top view. The liquid inlet 131 and the liquid outlet 132 are located on one of the short sides of the rectangular heat dissipation structure 133, and the conductive end 136 is located on the other short side of the rectangular heat dissipation structure 133. The first heat dissipation area 134 and the second heat dissipation area 135 are respectively arranged along the two long sides of the rectangular heat dissipation structure 133. Liquid flows sequentially through the liquid inlet 131, the first heat dissipation area 134 of the heat dissipation structure 133, the conductive end 136, the second heat dissipation area 135 of the heat dissipation structure 133, and the liquid outlet 132.

[0005] In this heat dissipation structure 133, several conduits are provided in the first heat dissipation area 134 and the second heat dissipation area 135. The length of these conduits increases as the heat dissipation structure 133 expands. The more fan modules 14 are provided, the longer the length of the conduits. For example, when three 120mm×120mm fan modules 14 are used, the length of the conduits is 360mm. The structure of the conduits in the heat dissipation structure 133 is a U-shaped structure, which means that the number of conduits provided in the first heat dissipation area 134 and the second heat dissipation area 135 of the heat dissipation structure 133 is only 6 to 7. When the number of conduits is small and the liquid pressure is fixed, the flow rate of the liquid in the conduits increases, which will greatly increase the friction effect. In addition, when the length is long, the friction effect will generate heat again, resulting in more heat that needs to be dissipated. This will have a negative impact on the cooling characteristics of the single-layer water-cooled radiator 1.

[0006] In this single-layer water-cooled radiator 1, additives are added to the liquid to reduce evaporation, reduce air lock, resist freezing, resist rust, resist corrosion, and improve thermal conductivity. However, the additives used have a lower flow rate than water, which will further reduce the flow rate of the liquid in the single-layer water-cooled radiator 1.

[0007] Please see Figure 3 To address the aforementioned issues, existing technology provides a dual-layer water-cooled radiator 2. This dual-layer water-cooled radiator 2 includes two stacked heat dissipation structures 21, a water inlet 22, a water outlet 23, and a connecting portion 24. The two heat dissipation structures 21 are rectangular. The water inlet 22 and the water outlet 23 are located on the shorter sides of the rectangular heat dissipation structures 21. Several conduits are disposed within the two heat dissipation structures 21. Although the number of conduits is doubled due to the dual-layer heat dissipation structure 21, the length of the conduits is still relatively long, limiting the improvement in heat dissipation efficiency. When the liquid flows into the two heat dissipation structures 21, the temperature is uniform. Air successively dissipates heat from the two heat dissipation structures 21 at the same temperature. When the air passes through the first heat dissipation structure 21, it has already been heated to a high temperature. When the high-temperature air passes through the second heat dissipation structure 21, the heat absorption effect is limited, affecting the cooling of the liquid. As computer capabilities increase, the heat generated by computers increases, and the required heat dissipation also gradually increases. However, due to the physical limitations of the computer case, simply increasing the length of the radiator is limited.

[0008] As can be seen from the above description, existing water-cooled heat dissipation devices have the following disadvantages:

[0009] 1. The catheter is too long:

[0010] In the existing water-cooled heat dissipation device, the heat pipes are connected to the two short sides of the rectangular heat dissipation structure 133. The length of the heat pipes is too long in combination with the number of fan modules. When the liquid flows in the excessively long heat pipes, the heat generated by friction will increase.

[0011] II. Liquid flow rate is too high:

[0012] As mentioned above, since the lengths of the two short sides of the rectangular heat dissipation structure are fixed, the number of conduits set in the first heat dissipation area 134 and the second heat dissipation area 135 of the heat dissipation structure 133 is only 6 to 7. This will limit the total flow rate of the liquid. When the pressure of the water pump module is fixed, the liquid in the conduit will flow at high speed, the friction effect between the liquid and the conduit will increase, and excess heat will be generated.

[0013] 3. Low air heat dissipation efficiency:

[0014] Although existing water-cooled radiators have multi-layer heat dissipation structures, the liquid flow channels in the heat dissipation structure are set in a U-shape. Therefore, the liquid temperature is the same in the multi-layer heat dissipation structure. When the air passes through the first heat dissipation structure, it has already been heated to a high temperature. When the high-temperature air passes through the second heat dissipation structure, it will be reheated, resulting in low air heat dissipation efficiency.

[0015] Therefore, designing a water-cooled heat dissipation device with a different structure that can increase liquid flow rate and improve air heat dissipation efficiency is a goal that relevant technical personnel urgently need to strive for. Utility Model Content

[0016] In view of this, the purpose of this utility model is to provide a gas-liquid heat exchange device, which includes a heat dissipation unit, a liquid inlet unit, and a liquid outlet unit.

[0017] The heat dissipation unit includes a heat sink structure, at least one first tube body disposed in the heat sink structure, and at least one second tube body disposed in the heat sink structure. The first tube body has a first liquid inlet end and a first liquid outlet end opposite to it. The second tube body has a second liquid inlet end and a second liquid outlet end opposite to it. The heat sink structure is generally rectangular and has two correspondingly disposed long sides and two correspondingly disposed short sides. The first liquid inlet end and the first liquid outlet end are respectively disposed on the two long sides, and the second liquid inlet end and the second liquid outlet end are respectively disposed on the two long sides.

[0018] The liquid inlet unit includes a liquid inlet pipe body connected to the first pipe body, and the liquid inlet pipe body is disposed on one of the long sides of the radiator structure.

[0019] The liquid outlet unit includes a liquid outlet pipe body connected to the second pipe body, and the liquid outlet pipe body is disposed on one of the long sides of the radiator structure.

[0020] In one embodiment, the liquid inlet unit further includes a liquid inlet surrounding wall disposed between the radiator structure and the liquid inlet pipe body, and a liquid inlet space defined by the liquid inlet surrounding wall. The liquid inlet surrounding wall is disposed on one of the long sides of the radiator structure, and the internal space of the liquid inlet pipe body, the internal space of the first pipe body and the liquid inlet space are interconnected.

[0021] In one embodiment, the liquid outlet unit further includes a liquid outlet surrounding wall disposed between the radiator structure and the liquid outlet pipe body, and a liquid outlet space defined by the liquid outlet surrounding wall. The liquid outlet surrounding wall is disposed on one of the long sides of the radiator structure, and the internal space of the liquid outlet pipe body, the internal space of the second pipe body and the liquid outlet space are interconnected.

[0022] In one embodiment, the inlet pipe is connected to the outlet surrounding wall and passes through the outlet space.

[0023] In one embodiment, the gas-liquid heat exchange device further includes a connection unit, which includes a connection surrounding wall connected to the radiator structure and a connection space defined by the connection surrounding wall. The connection surrounding wall is disposed on one of the long sides of the radiator structure, and the internal space of the first tube, the internal space of the second tube, and the connection space are interconnected.

[0024] In one embodiment, the heat dissipation unit defines a dividing line disposed in the radiator structure, the dividing line dividing the radiator structure into two areas, an inlet area and an outlet area, from two corresponding long sides, the first pipe body is disposed on the long side of the inlet area, and the second pipe body is disposed on the long side of the outlet area.

[0025] In one embodiment, the radiator structure has a first heat dissipation component connected to the first tube body and a second heat dissipation component connected to the second tube body, and the first heat dissipation component and the second heat dissipation component are stacked together.

[0026] In one embodiment, the radiator structure allows airflow, and the first heat dissipation component is positioned downwind of the second heat dissipation component.

[0027] In one embodiment, the heat dissipation unit further includes two side protection bodies connected to the heat sink structure. The two side protection bodies are respectively arranged along the two short sides. The heat sink structure has a number of fins arranged at intervals from each other. The number of fins are respectively connected to the first and second tube bodies.

[0028] In one embodiment, the heat dissipation unit includes several fixing bodies connected to the heat sink structure, and several fixing members disposed on the several fixing bodies, with the several fixing bodies respectively disposed along the two long sides.

[0029] The beneficial effects of this invention are that the first and second pipes connect to the long side of the radiator structure, so the lengths of the first and second pipes are consistent with the short side of the radiator structure. Compared with known technologies, the first and second pipes have shorter lengths and a greater number. The shorter length of the first and second pipes reduces the frictional effect generated when the liquid flows through them, and the greater number of first and second pipes increases the overall flow rate. Furthermore, the first heat dissipation component is positioned downwind of the second heat dissipation component. The liquid temperature in the first heat dissipation component is higher than that in the second heat dissipation component. Air first passes through the lower-temperature second heat dissipation component and then through the higher-temperature first heat dissipation component, resulting in even lower temperatures exiting from the second pipe.

[0087] The features and technical content of this utility model will be clearly presented in the following detailed description of two embodiments with reference to the accompanying drawings. It should be noted before the detailed description that similar components are represented by the same reference numerals.

[0088] Please see Figure 4 , Figure 5 and Figure 6 This is a first embodiment of a gas-liquid heat exchange device of the present invention. The gas-liquid heat exchange device includes a heat dissipation unit 3, a liquid inlet unit 4, a liquid outlet unit 5, and a connection unit 6.

[0089] The heat dissipation unit 3 includes a heat sink structure 31, at least one first tube 32 disposed in the heat sink structure 31, at least one second tube 33 disposed in the heat sink structure 31, two side protection bodies 34 connected to the heat sink structure 31, several fixing bodies 35 connected to the heat sink structure 31, and several fixing members 36 disposed on the several fixing bodies 35. In this first embodiment, the number of first tubes 32 is several, and the number of second tubes 33 is several, but it is not limited thereto.

[0090] The liquid inlet unit 4 includes a liquid inlet pipe 41 connected to the first pipe 32, a liquid inlet surrounding wall 42 disposed between the radiator structure 31 and the liquid inlet pipe 41, and a liquid inlet space 43 defined by the liquid inlet surrounding wall 42 (e.g., Figure 9 (As shown). In this first embodiment, the inlet pipe 41 is connected to the plurality of first pipes 32 via the inlet surrounding wall 42. In actual implementation, the inlet surrounding wall 42 and the inlet space 43 may be omitted, and the first pipes 32 may be directly connected to the inlet pipe 41. This should not be considered a limitation. In some embodiments, the inlet pipe 41 is configured as... Figure 2 and Figure 3 The connector structure is designed for the installation of liquid hoses.

[0091] The liquid outlet unit 5 includes a liquid outlet pipe 51 connected to the second pipe 33, a liquid outlet surrounding wall 52 disposed between the radiator structure 31 and the liquid outlet pipe 51, and a liquid outlet space 53 defined by the liquid outlet surrounding wall 52. In this first embodiment, the liquid outlet pipe 51 is connected to the second pipe 33 through the liquid outlet surrounding wall 52. In actual implementation, the liquid outlet surrounding wall 52 and the liquid outlet space 53 may be omitted, and the second pipe 33 may be directly connected to the liquid outlet pipe 51. This should not be a limitation. In some embodiments, the liquid outlet pipe 51 is configured as follows: Figure 2 and Figure 3 The connector structure is designed for the installation of liquid hoses.

[0092] The connection unit 6 includes a connection surrounding wall 61 connected to the heat sink structure 31, and a connection space 62 defined by the connection surrounding wall 61.

[0093] The heat sink structure 31 is generally rectangular and has two corresponding long sides 311 and two corresponding short sides 312. Air can flow through the top and bottom surfaces of the heat sink structure 31, but air cannot pass through the long sides 311 and the short sides 312.

[0094] The inlet pipe 41 and the inlet surrounding wall 42 are disposed on one of the long sides 311 of the radiator structure 31. The outlet pipe 51 and the outlet surrounding wall 52 are disposed on one of the long sides 311 of the radiator structure 31. The connecting surrounding wall 61 is disposed on one of the long sides 311 of the radiator structure 31. In this first embodiment, the inlet pipe 41, the inlet surrounding wall 42, the outlet pipe 51, and the outlet surrounding wall 52 are disposed on the same long side 311, and the connecting surrounding wall 61 is disposed on the other long side 311 of the radiator structure 31. In some embodiments, the inlet pipe 41 and the inlet surrounding wall 42 are disposed on one of the long sides 311 of the radiator structure 31, the outlet pipe 51 and the outlet surrounding wall 52 are disposed on the other long side 311 of the radiator structure 31, and the connecting unit 6 is not provided.

[0095] The first tube 32 and the second tube 33 are both connected to the two long sides 311 of the radiator structure 31, and the first tube 32 and the second tube 33 are perpendicular to the two long sides 311 of the radiator structure 31.

[0096] The first tube 32 has a first liquid inlet 321 and a first liquid outlet 322, which are opposite to each other. The first liquid inlet 321 and the first liquid outlet 322 are respectively disposed on the two long side portions 311. The first liquid inlet 321 is connected to the liquid inlet surrounding wall 42, and the first liquid outlet 322 is connected to the connecting surrounding wall 61.

[0097] The second tube 33 has a second inlet end 331 and a second outlet end 332, which are opposite to each other. The second inlet end 331 and the second outlet end 332 are respectively disposed on the two long sides 311. The second inlet end 331 is connected to the connecting surrounding wall 61, and the second outlet end 332 is connected to the outlet surrounding wall 52.

[0098] The internal spaces of the inlet pipe 41, the first pipe 32, and the inlet space 43 are interconnected. The internal spaces of the outlet pipe 51, the second pipe 33, and the outlet space 53 are interconnected. The internal spaces of the first pipe 32, the second pipe 33, and the connecting space 62 are interconnected. The liquid flow sequence in the gas-liquid heat exchange device is: inlet pipe 41, inlet surrounding wall 42, first pipe 32, connecting surrounding wall 61, second pipe 33, outlet surrounding wall 52, and outlet pipe 51. The inlet pipe 41 and outlet pipe 51 are used to connect a water pump module 11 (see [link]). Figure 1 ), to drive the flow of liquid.

[0099] The heat dissipation unit 3 defines a dividing line H1 within the radiator structure 31. This dividing line H1 separates the radiator structure 31 into two regions: an inlet region H11 and an outlet region H12, originating from two corresponding long sides 311. Several first tubes 32 are located on the long side 311 of the inlet region H11, and several second tubes 33 are located on the long side 311 of the outlet region H12. In the gas-liquid heat exchange device, the liquid first enters the first tubes 32 in the inlet region H11 and then enters the second tubes 33 in the outlet region H12. Figure 4 and Figure 5 In the diagram, the dividing line H1, the inlet area H11, and the outlet area H12 are indicated by dashed lines to show their boundaries and ranges.

[0100] The two protective bodies 34 are respectively arranged along the two short sides 312. In the first embodiment, the two short sides 312 of the heat sink structure 31 are baffles, and the two protective bodies 34 are protective plates arranged on the outside of the two short sides 312.

[0101] The plurality of fixing bodies 35 are respectively arranged along the two long sides 311. The structure of the plurality of fixing bodies 35 is a fixing frame. The plurality of fixing members 36 can be provided with screws or other fasteners to install the gas-liquid heat exchange device in a computer, or to install two or more cooling fans on the plurality of fixing bodies 35. In this first embodiment, the fixing member 36 is a screw hole, but is not limited thereto. The two long sides 311 of the heat sink structure 31 are located at the bottom of the fixing bodies 35 and are covered by the plurality of fixing bodies 35, therefore... Figure 4In the diagram, the two long sides 311 of the radiator structure 31 are represented by a dashed area filled with several diagonal lines.

[0102] See also Figure 4 and Figure 7 ,Should Figure 7 for Figure 4 A partially enlarged schematic diagram of the central region W. The radiator structure 31 has several fins 313 spaced apart from each other. These fins 313 are connected to the first tube 32 and the second tube 33, respectively. In the water inlet region H11, several first tubes 32 are arranged in parallel, spaced apart from each other, with several fins 313 positioned between them. Similarly, in the water outlet region H12, several second tubes 33 are arranged in parallel, spaced apart from each other, with several fins 313 positioned between them. Several fins 313 are also positioned between the first tubes 32 and the second tubes 33 between the water inlet region H11 and the water outlet region H12. The liquid contained in the first tube 32 and the second tube 33 is at a high temperature. After absorbing the heat from the liquid, the first tube 32 and the second tube 33 will conduct the heat to the plurality of fins 313. The plurality of first tubes 32, the plurality of second tubes 33 and the plurality of fins 313 cooperate to define a plurality of airflow channels. After the air passes through the plurality of airflow channels, it can carry away the heat in the plurality of first tubes 32, the plurality of second tubes 33 and the plurality of fins 313, thereby achieving the effect of cooling the liquid. In some embodiments, the heat sink structure 31 is a three-dimensional structure with a plurality of fins 313, and the plurality of first tubes 32 and the plurality of second tubes 33 are inserted into the plurality of fins 313. In some embodiments, the fin 313 is a wavy metal sheet, disposed between two spaced-apart first tubes 32, between two spaced-apart second tubes 33, and between adjacent first tubes 32 and second tubes 33. In some embodiments, the cross-section of the first tube 32 and the second tube 33 is an elongated square, and the plurality of fins 313 are connected to the long sides of the first tube 32 and the second tube 33.

[0103] It is worth mentioning that the two ends of the conduit in the existing water cooling heat dissipation device are connected to the two short sides 312 of the heat dissipation structure 31. The first liquid inlet 321 and the first liquid outlet 322 of the first tube body 32 of this utility model, and the second liquid inlet 331 and the second liquid outlet 332 of the second tube body 33 are respectively connected to the two long sides 311 of the heat dissipation structure 31. Therefore, compared with the conduit of the existing water cooling heat dissipation device, the first tube body 32 and the second tube body 33 of this utility model have shorter lengths and more numbers.

[0104] Since the water pump module connected to the gas-liquid heat exchange device has a fixed pressurization capacity, a larger number of first tubes 32 and second tubes 33 arranged in parallel can increase the total liquid flow rate, reduce the liquid flow velocity in the first tubes 32 and second tubes 33, and increase the time the liquid stays in the radiator structure 31, so that the first tubes 32 and second tubes 33 can remove more heat from the liquid.

[0105] When the liquid flows through the first tube 32 and the second tube 33 at a lower flow rate, the frictional effect between the liquid and the inner tube wall is significantly reduced. Furthermore, the shorter length of the first tube 32 and the second tube 33 also significantly reduces the heat generated by friction, greatly improving the heat dissipation effect of the gas-liquid heat exchange device. In addition, a slower liquid flow rate in the first tube 32 and the second tube 33 results in a more uniform flow rate among the several parallel-connected first tubes 32 and second tubes 33.

[0106] Compared with the prior art, the gas-liquid heat exchange device of this utility model allows for higher heat dissipation performance under the same shape and structure, and regardless of the expansion of the long side 311 of the radiator structure 31, the first tube 32 and the second tube 33 of the same length can be provided.

[0107] Please see Figure 8 and Figure 9 This is a second embodiment of the gas-liquid heat exchange device of the present invention. The second embodiment is largely the same as the first embodiment, and the similarities will not be described in detail here. The difference is that the radiator structure 31 has a first heat dissipation component 314 connected to the first tube 32 and a second heat dissipation component 315 connected to the second tube 33, and the first heat dissipation component 314 and the second heat dissipation component 315 are stacked together.

[0108] The liquid inlet surrounding wall 42 is disposed on the side of the first heat dissipation assembly 314, the liquid outlet surrounding wall 52 is disposed on the side of the second heat dissipation assembly 315, and the connecting surrounding wall 61 is disposed on the sides of the first heat dissipation assembly 314 and the second heat dissipation assembly 315. The first tube 32 and the second tube 33 are connected to the two long sides 311 of the radiator structure 31, and the first tube 32 and the second tube 33 are perpendicular to the two long sides 311 of the radiator structure 31. The first tube 32 and the second tube 33 are arranged in a counter-current configuration.

[0109] The heat sink structure 31 allows air to flow through it, and the first heat sink component 314 is positioned downwind of the second heat sink component 315. In this second embodiment, the first heat sink component 314 is located below the second heat sink component 315. Several cooling fans (not shown) are mounted on a fixing body 35 located below the second heat sink component 315. The fixing body 35 located above the first heat sink component 314 is fixed in the computer case (not shown). The several cooling fans drive air into the second heat sink component 315, then into the first heat sink component 314, and finally exhaust it outward from the computer case.

[0110] In the configuration of the gas-liquid heat exchange device in the second embodiment, the hot liquid from the inlet pipe 41 first passes through the first pipe 32 in the first heat dissipation component 314. The first heat dissipation component 314 receives the warm air flowing through the second heat dissipation component 315, and the liquid undergoes the first heat dissipation. The liquid then enters the second pipe 33 in the second heat dissipation component 315 through the connection space 62. The cooling fan drives the cold air to dissipate the liquid a second time. The cooled liquid is discharged from the gas-liquid heat exchange device through the outlet pipe 51.

[0111] The first heat dissipation component 314 is positioned downwind of the second heat dissipation component 315, which ensures higher heat dissipation efficiency and avoids the reheating disadvantage typical of prior art in multi-layer heat sinks. It not only retains a low friction effect but also improves the air cooling effect.

[0112] In this embodiment, to ensure that the inlet pipe 41 and the outlet pipe 51 have the same opening direction, the inlet pipe 41 is connected to the outlet surrounding wall 52 and passes through the outlet space 53. In this second embodiment, the inlet of the inlet pipe 41 faces downwards, and the inlet of the outlet pipe 51 faces downwards. When the gas-liquid heat exchange device is installed in the computer casing, the inlets of both the inlet pipe 41 and the outlet pipe 51 can face towards the motherboard, facilitating the installation of the liquid hose.

[0113] Please see Figure 9 The long side 311 of the radiator structure 31 is a partition, and the long side 311 of the radiator structure 31 exposes the opening shape of the plurality of first tubes 32 and the opening shape of the plurality of second tubes 33. The internal space of the first tube 32 is connected to the liquid inlet space 43, and the internal space of the second tube 33 is connected to the liquid outlet space 53. In addition, the long side 311 of the side of the connecting space 62 also has the same structure, so that the connecting space 62 is connected to the internal space of the first tube 32 and the second tube 33 respectively.

[0114] This utility model gas-liquid heat exchange device has the following characteristics:

[0115] 1. The plurality of fixing bodies 35 and the plurality of fixing members 36 can provide a plurality of cooling fans arranged on one side of the gas-liquid heat exchange device. The length of the first tube 32 and the second tube 33 is less than the length of the long side portion 311 of the radiator structure 31. The first tube 32 and the second tube 33 are perpendicular to the long side portion 311 of the radiator structure 31.

[0116] 2. Regardless of how many cooling fans are installed on the plurality of fixing bodies 35 and the plurality of fixing members 36, or how the length of the long side portion 311 of the radiator structure 31 changes, the first tube 32 and the second tube 33 have the same length.

[0117] 3. The radiator structure 31 can also be configured as a double-layer heat dissipation structure composed of the first heat dissipation component 314 and the second heat dissipation component 315, wherein the length of the first tube 32 and the second tube 33 is less than the length of the long side portion 311 of the radiator structure 31, and the first tube 32 and the second tube 33 are perpendicular to the long side portion 311 of the radiator structure 31.

[0118] 4. A computer liquid cooling system equipped with the gas-liquid heat exchange device, wherein the plurality of fixing bodies 35 and the plurality of fixing members 36 can provide a plurality of cooling fans arranged on one side of the gas-liquid heat exchange device, and the first tube body 32 and the second tube body 33 are perpendicular to the long side 311 of the heat sink structure 31.

[0119] 5. A computer liquid cooling system equipped with the gas-liquid heat exchange device, wherein the heat sink structure 31 may also be configured as a double-layer heat dissipation structure composed of the first heat dissipation component 314 and the second heat dissipation component 315, which adopts a double row of pipes in a counter-flow configuration, wherein the plurality of fixing bodies 35 and the plurality of fixing members 36 can provide a plurality of cooling fans arranged on one side of the gas-liquid heat exchange device, wherein the length of the first pipe body 32 and the second pipe body 33 is less than the length of the long side portion 311 of the heat sink structure 31, and the first pipe body 32 and the second pipe body 33 are perpendicular to the long side portion 311 of the heat sink structure 31.

[0120] As can be seen from the above description, the gas-liquid heat exchange device of this utility model does indeed have the following effects:

[0121] I. Effectively shorten the length of the catheter:

[0122] The radiator structure 31 is generally rectangular and has two corresponding long sides 311 and two corresponding short sides 312. Regardless of how the length of the long side 311 of the radiator structure 31 changes, or how many cooling fans are installed on the side of the radiator structure 31, the lengths of the first tube 32 and the second tube 33, which are perpendicular to the long side 311, are the same as those of the short side 312 and will not change. Compared with the general radiator in which the length of the liquid pipe is equal to the long side of the rectangular radiator, this utility model effectively shortens the length of the first tube 32 and the second tube 33.

[0123] II. Effectively slows down the flow rate of the liquid:

[0124] The plurality of first tubes 32 and the plurality of second tubes 33 are arranged on the two long sides 311 of the radiator structure 31. Since the long sides 311 have a long installation area, the number of first tubes 32 and second tubes 33 is significantly greater than the number of liquid pipes in a typical radiator. This will greatly increase the total liquid flow rate of this invention and reduce the liquid flow velocity in the first tubes 32 and second tubes 33, thereby reducing the friction effect between the liquid and the tube wall.

[0125] III. Significantly improves the efficiency of air heat dissipation:

[0126] The radiator structure 31 allows air to flow through it. The first heat dissipation component 314 is located downwind of the second heat dissipation component 315. The cold air first contacts the second heat dissipation component 315 to dissipate heat from the liquid inside, so that the liquid flowing out of the second heat dissipation component 315 has the lowest temperature. Then the air enters the first heat dissipation component 314 to cool down the hottest liquid inside before being discharged. The above structure effectively avoids secondary heating of the liquid in the second heat dissipation component 315 and effectively improves the heat dissipation efficiency of the air.

[0127] In summary, the liquid inlet unit 4, the liquid outlet unit 5, and the connecting unit 6 are disposed on the two long sides 311 of the radiator structure 31. The plurality of first tubes 32 and the plurality of second tubes 33 are arranged on the two long sides 311 of the radiator structure 31. The above-mentioned structural features can shorten the length of the first tubes 32 and the second tubes 33 and reduce the flow rate of the liquid in the first tubes 32 and the second tubes 33, which can significantly reduce the friction effect generated by the liquid, thereby reducing the excess heat generated by the friction effect. The radiator structure 31 can also be configured as a double-layer heat dissipation structure composed of the first heat dissipation component 314 and the second heat dissipation component 315. The first heat dissipation component 314 is located downwind of the second heat dissipation component 315, which can avoid secondary heating of the liquid in the second heat dissipation component 315 and effectively improve the heat dissipation efficiency of the air. Therefore, the purpose of this utility model can indeed be achieved.

[0128] The above description is merely two embodiments of this utility model and should not be construed as limiting the scope of implementation of this utility model. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the utility model shall still fall within the scope of this utility model patent.
