The heat generated by the CPU (heat generating body) that is being mounted is increased, and the cooling of the CPU is becoming more and more important. Conventionally, in order to cool the CPU, an air-cooling fan-type heat sink is used. However, the fan noise or the cooling limit of the air-cooling method is a problem of the book (cl〇se_up). Generation cooling methods, liquid cooling jackets (also known as water-cooled jackets, liquid cooling modules [module]) are attracting attention. (7) In the patent document, for example, in the patent document, a liquid-cooled jacket in which a metal pipe having an inlet port and an #outlet is provided at both ends is proposed. [Patent Document 1] Japanese Laid-Open Patent Publication No. SHO 63-293865 (Second-up, second, second, second, second, second, first, second, and second) In the case of the cooling water flow, ^, the pressure loss of the cooling water becomes large. In this way, not only is it impossible to cool the CPU efficiently, but there is a problem that the output of the pump becomes large. ^ In order to solve the above problems, the present invention provides a liquid cooling jacket which can efficiently generate a heat generating body such as a cold portion CPU. In the present invention, the heat generating body is attached to a predetermined position, and the heat generated by the heat generating body is supplied from the external wheeled fluid supply device and is transmitted to the inside of the heat transfer. The fluid cooling jacket E includes: a first flow path on the heat transfer fluid supply device side; a second flow path group formed by a plurality of second flow paths diverging from the P flow path; and the plurality of The downstream side of the second flow path is a third flow path in which the plurality of second flow paths are combined; wherein the heat generating body is mainly used for heat exchange in the second flow path group. According to such a liquid cooling jacket S, the heat transport flow system from the external heat transfer fluid supply device is supplied to the first flow path. Next, it flows in the order of the second flow path group and the third flow path. X. The heat generated by the heat generating body is mainly transmitted to the heat transfer fluid by heat exchange by the second flow path group. As a result, the heat generating system is appropriately cooled. Here, the second flow path group is formed by a plurality of second flow paths that are diverged from the first flow path, and the plurality of second flow paths are formed into a third flow path set and the second flow path. In the case of the snake-like situation, the length of each of the second flow paths is changed to the amplitude of the flow path A of the flow path A of the first flow path of the fourth flow path. The pressure loss of the heat transfer fluid of the second flow path is also drastically reduced. Further, the adjacent second flow path in the present invention is similar to the second flow paths B5a and B5a of the liquid-cooling jacket J6 of the sixth embodiment to be described later (refer to Fig. 26), and is not completely isolated. can. 201113988 Therefore, according to such a liquid-cooled jacket, a small external heat transfer fluid supply device (for example, a pump) is used to supply a heat transfer fluid to be circulated in the liquid cooling jacket, which can be efficiently cooled. A heat generator such as cpu. Moreover, the present invention is a liquid cooling package in which a heat generating body is attached to a heat generating fluid at a predetermined position, and heat generated by the heat generating body is supplied from the outside to the inside of the heat transfer fluid. The lower flow side includes: a first flow path, a second flow path group composed of a plurality of second flow paths, and a third flow path; wherein the heat generating body is mainly in the second flow path group For heat exchange, the adjacent second flow path groups are connected in series via a connection flow path. That is, the second flow path group includes a plurality of second flow path group portions, and the plurality of second flow path group portions are liquid-cooled ferrules arranged in series. According to the liquid cooling (four) of this type, the second flow path group (second flow path group portion) having the in-order number = via the connection flow path can be provided in the plural first path group and the heat generating body. Exchange between them. = The adjacent second flow path groups are adjacent to each other, and one of the other side and the other side of the upper flow end are on the same side. The second flow path group adjacent to each other is disposed at the same time, and the other upstream end is attached to the liquid cooling jacket on the same side. In the flow direction, via the adjacent second flow path t system, the other side of the adjacent second flow path group of the heat exchange fluid is: a group of squares, a connecting flow path, and a phase plane liquid cooling The size of the way to circulate. Therefore, when the number of the second flow paths of the second flow path group does not change the number of the second flow path groups that constitute each of the second flow paths, 201113988 constitutes: the second flow of the second flow path group will flow through The liquid cooling jacket _ 】 the area is smaller. Since the number of the two-way flow group is increased: the flow rate is - timing, and the first flow rate is increased. Therefore, the heat transfer fluid in the liquid flow path becomes large, and as a result, the heat resistance of the liquid cooling entanglement is lowered. It is conveyed that the adjacent second flow path groups are not arranged in parallel, and in the example direction, they are arranged in a line, and the muscle path is

When the number of the second flow paths constituting each of the second flow path groups is short, the cross-sectional area thereof is not small, and the heat resistance of the heat exchange-I liquid cooling (4) does not decrease, and the flow velocity of the body is not changed. In this case, the liquid cooling side can be the same side, and as a result, the process of changing the number of the second flow path group as the inlet and the outlet of the heat transfer fluid of the even number of sets ε in the piping connected to the liquid cooling jacket A tube bundle that is easy to manufacture is bundled, and each of the tubes has a plurality of metal hollow portions as the second flow path. The liquid-cooled ferrule of this type is a bundle of tubes which are bundled with a plurality of metal tubes, and the hollow portion of each tube serves as the second flow path, so that the liquid-cooling ferrule can be easily formed. In addition, the number and thickness (running cross-sectional area) of the second flow path can be easily changed by appropriately changing the number, thickness, and the like of the metal pipe to be bound. X ^ is further provided with a metal pipe having a plurality of hollow portions, and each of the hollow portions is the second flow path. According to such a liquid-cooled jacket, a liquid-cooled jacket can be easily constructed by using a metal pipe having a plurality of hollow portions. 201113988 Further, a plurality of metal fins arranged at predetermined intervals are provided, and a second flow path is formed between adjacent fins. According to such a liquid-cooled jacket, heat from the heat generating body can be transmitted to the heat transfer fluid flowing through the second flow path via the plurality of fins by using the adjacent fins as the second flow path. . Further, the width W of the second flow path is 〇. 2~1. 〇fflm. According to such a liquid-cooled jacket, the heat resistance and the pressure loss by the internal heat transfer fluid can be regarded as a good range. Further, the width W of the second flow path and the thickness τ of the fin between the adjacent second flow paths satisfy the following formula (1): _〇. 375 XW + 0. 875 g T/¥ S - 1. 875 XW + 3. 275 ... (1). According to such a liquid-cooled jacket, the heat resistance is small, and heat exchange is favorably performed between the heat generating body and the heat transfer fluid. Further, the depth D and the width w of the second flow path satisfy the following formula (2) · · 5 X W + 1 $ D $ 16. 25 X W + 2. 75 (2). According to such a liquid-cooled jacket, the heat resistance is small, and heat exchange is favorably performed between the heat generating body and the heat transfer fluid. Further, the present invention includes: a fin element including a plurality of metal fins and a substrate in which the plurality of metal fins are erected; and a ferrule body accommodating the fin element; The casing body can be fixed in a heat exchange manner. In the liquid-cooling jacket of this type, for example, a metal extruded member including a bottom plate constituting the substrate and a plurality of fins on which the bottom plate is erected is cut, and the above-mentioned plural is produced. The fins of the metal fins 201113988: The liquid fins can then be formed by fixing the fin elements to, for example, a box-shaped ferrule body. Further, for example, a fin element having a plurality of metal fins can be produced by forming a plurality of grooves in a metal block (1). In the 兮Γ :: first fin element a first substrate and a plurality of 'th fins' on which the first substrate is erected; a first substrate; and a plurality of the first "" fins that are erected on the second substrate The element and the second sheet element system, ΐ = Γ the first scale and the plurality of second fins are mutually (four), and the plurality of fins of the metal are by the first fin = and The second Korean piece is configured such that the second flow path is formed between the adjacent first fin and the first fin. Two defects: the liquid cooling g of the type is a plurality of a Korean piece and a plurality of mutual inter-points, even if the first fins are spaced apart from each other and the second fins are spaced apart, the spacing of adjacent metal Korean films, that is, the fins and the second fins, may be The interval between the sheets is narrowed. The heat generating system is mounted on the first substrate side, and the protruding length of the fins is set. In order to be the same as or shorter than the protruding length of the second Korean film, the plurality of second pieces and the first substrate are thermally connected to each other by the protruding length of the first Korean piece and the second When the Handing, the protruding length is the same, or the second chip element and the second Korean element are combined as compared with the protruding length of the second fin, a plurality of pieces are reliably abutted on the first substrate, and The plurality of second fins are joined to the first substrate of 201113988 in a heat exchange manner.

The ", can be transmitted to the second & the hot-wheeling fluid flowing between the first fin and the second fin. - having a metal fin for accommodating the plurality of Fin containment

And a casing body and a sealing body for sealing the fin accommodation chamber; wherein a peripheral wall of the casing body surrounding the fin accommodation chamber and the sealing body door are disposed. (4) which is frictionally agitated and joined, the beginning and the end of the friction stir joining may overlap. According to the liquid cooling jacket E of this type, the peripheral wall of the body and the sealing body can be well joined by the start of the frictional engagement and the weight 4. Thereby, the heat transfer fluid is less likely to leak to the outside. The human horse does not use the welding material', and the sealing body and the ferrule body are joined by friction feeding, so that there is no fear that the heat transfer fluid (refrigerant) is contaminated by the welding material or the like, and there is no need to worry about constituting the liquid cooling system. A machine such as a micro pump or a radiator is corroded by a welding material or the like. Further, the plurality of metal fins are erected on the sealing body and integrated with the sealing body. According to such a liquid-cooled ferrule, the production of the liquid-cooled ferrule by the sealing fin-finished fins in the fin-sealing chamber can be reduced. Further, in this manner, a plurality of metal fins and a film containing chamber are provided, and a plurality of predetermined positions of gold can be used. That is, not only can it be easily produced, but it can be produced into a metal fin and a sealed body which is a body of the 201113988 body. For example, as described in the fifth embodiment to be described later, the plate made of the alloy can be made of (Sheet) obtained by skive processing. Further, in this manner, when the fin and the sealing body are integrally formed by the scraping process or the like, it is of course unnecessary to join the fin and the sealing body with a welding material or the like, thereby preventing contamination of the heat transfer fluid or the like. Moreover, since the fin and the sealing body are integrated, the heat transfer between the two is high. Therefore, when a heat generating body such as a CPU is attached to the sealing body, the heat of the heat generating body is favorably transmitted to the plurality of fins via the sealing body. As a result, the heat generating property of the heat generating body in the liquid cooling jacket becomes high. And Δ again, the peripheral wall is not deformed on the outer side, and the surface is abutted against the jig by the friction stir welding. According to such a liquid cooling jacket S', by friction stir welding on one side of the peripheral wall abutting the jig, the peripheral wall is not easily changed on the outer side by friction stir welding: Second, as described above, by the abutment jig 'peripheral wall thin Even after being taught by friction. The outer peripheral surface of the shoulder (sh〇uider) in the tool to be used: the gap between the circumferential surfaces), for example, below ~, the peripheral wall is not deformed' can be used for friction stir welding. The length of the pin of the tool used in the above friction stir joining is the same as 60% or less of the thickness of the upper sealing body. According to the liquid-cooling ferrule of this type, the length of the pin of the seal riding Mr.-one is less than 6〇% of the thickness of the sealing body, and the casting is joined by friction stir welding, and the sealing body is on the side of the fin receiving chamber. Not easily deformed. This will become smaller. The volume of the one receiving chamber is removed. The above-mentioned tool is pulled out again from the above-mentioned mating portion in the above-mentioned friction stir welding 10 201113988. According to the liquid cooling jacket g of this type, the extraction position of the tool is inserted from the above-mentioned fitting port, and the pin-out of the pin is not formed at the fitting portion. Thereby, the sleeve body and the sealing body can be suitably joined. Further, a honeycomb honeycomb body having a plurality of fine pores is provided, and the pores are the second flow passages. According to such a liquid cooling jacket E, by using the pores of the honeycomb body as the second flow path, the heat of the heat generating body can be transmitted to the heat transfer fluid flowing through the second flow path via the honeycomb body. Further, the present invention includes: a heat exchange sheet made of a metal having a corrugated cross section; and a metal ferrule body fixed to the heat exchange sheet by heat exchange; wherein the heat exchange sheet and the ferrule body are The second flow path described above is formed. According to such a liquid-cooled jacket, the heat exchange sheet having a corrugated cross section can be easily fixed by heat-exchangeable in the sleeve body. D, 'The above metal is aluminum or aluminum alloy. According to such a liquid-cooled jacket, it is lightweight by using a metal as aluminum or an aluminum alloy. Further, the inlet port of the heat transfer fluid that communicates with the first flow path and the discharge port of the heat transfer fluid that communicates with the third flow path are symmetrically arranged around the heat generating body. According to such a heat transfer flow system in which the liquid cooling jacket H' is supplied from the inlet port to the first flow path, the second flow path in the vicinity of the heat generating body can be easily flowed. Thereby, the heat transfer fluid can be suitably placed between the heat generating body and the heat generating body, and the inlet port and the discharge port are relatively far apart. According to such a liquid-cooled jacket, the heat transport flow system supplied from the inlet port to the first flow path can facilitate the entire flow of the plurality of second flow paths. By this, it is possible to suitably exchange heat between the heat transfer fluid and the heat generating body of the entire second flow path. Further, the inlet port and the discharge port are disposed to be relatively close to the heat generating body. According to such a liquid-cooled jacket, the heat transport flow system supplied from the inlet port to the first flow path makes it easy to flow the second flow path in the vicinity of the heat generating body at a rapid flow rate. Thereby, heat exchange between the heat transfer fluid and the heat generating body flowing at this rapid flow rate can be suitably performed. That is, for example, a heat generating system such as a CPU does not pass through a heat diffusion sheet 102 (refer to FIG. 3) called a heat spreader, and is installed in a liquid cooling jacket, and heat of the heat generating body is hard to be transmitted. When the entire liquid cooling jacket is reached, the heat transfer fluid can be efficiently radiated by flowing the second flow path in the vicinity of the heat generating body at a rapid flow rate. Further, the above heat generation system is a CPU. According to this type of liquid-cooled ferrule, heat is efficiently exchanged between the CPU and the heat transfer fluid to cool the CPU. According to the present invention, it is possible to provide a liquid cooling jacket that efficiently cools a heat generating body such as a CPU.

While the heat is being heated, the heat exchange with the internal cooling water of the L-flow meat A and /; L will be accepted from the CPU 101, and the 5-6 gentlemen will be transported to the cold water. As a result, the CPU 101 is efficiently cooled. Further, the heat diffusion sheet 102 is a sheet for efficiently transferring the heat of the CPU 101 to the bottom wall u of the sleeve body 10 to be described later, and is formed of, for example, a metal having high thermal conductivity such as copper. Such a liquid-cooled jacket η system mainly includes a sleeve body 1G, a flat tube bundle 20 (tube bundle), and a lid unit 3G as shown in Figs. 4 to 7. Set of body 10' flat tube bundle 20: cover unit 3. As long as it is not specifically recorded, it is formed by Shao or Minghe. Thereby, the liquid cooling jacket is lighter in weight and easy to install. <Rack body> The casing E is a shallow-bottomed case (see Fig. 7) that is open on the upper side (one side), and has a bottom wall u and a peripheral wall 12, and a storage chamber for accommodating a flat S bundle on the inner side thereof. (Refer to Figure 7). Such a sleeve body is made of, for example, die-casting, casting, forging, and the like. Further, the sleeve body is provided with a position fitting portion 14 corresponding to the shape of the notch portion 31c of the cap body 31 to be described later on 14201113988. <flat tube bundle> Flat tube bundle 2. Attached to the E body! . Inside, a space 10a and a space 1 come and go to Chu / "face, the end of the pottery side of the tower ▲ people 5 map", by, 5 gold constitute welding consumables, in the bottom of the S body The wall u is heat-exchanged (heat-moving) in a way that is joined and fixed (refer to Figure 6). ^Inter-l〇a is used as the function of the first flow path ^, and the function of the space system C1.

The flat s-beam 20 is an object in which a predetermined number of flat tubes 21 are bound and joined in the thickness direction thereof (refer to Figs. 6 and 7). Each of the flat tubes has one or a plurality of (two in the first embodiment) hollow portions 2 i. = each of the hollow portions 21a is a second flow path that flows as cooling water, that is, the cross section of each of the second flow paths Bla is rectangular, and the peripheral wall 21b of the flat tubes 21 located on both sides thereof The side wall portion (the second flow (four) portion) and the upper wall portion (second flow path configuration portion) or the lower wall portion (the second flow path structure) constituted by the peripheral wall 21b or the partition wall 21j located on the upper and lower sides thereof The flat tube bundle 20 has a second flow path group M composed of a plurality of second flow paths, that is, a plurality of second flow paths Bla. Here, the CPU 101 is as described above. The heat is applied to the hollow portion 21a surrounding the flat tubes 21 via the bottom wall 11' via the bottom wall 11'. The peripheral wall 21b of the second flow path Bla and the buckle partition wall 21c that partitions the adjacent hollow portion 21a. Further, the heat transmitted to the peripheral wall 21b and the partition wall 21c (the exchange portion) is transmitted to the second flow. The cooling of the flow path Bla l 15 201113988 This 'CPU 101 system becomes the water heat exchange. Mainly and the cold part of the second flow path group B1 In addition, by transferring a plurality of flat heats from (10) m and restraining them, the flat tube bundles I 21b (heat exchange portions) are increased, and the cold wall water is directly exchanged for heat exchange, thereby effectively cooling the water. Efficiently cool CPU 1 01. = 2, the second flow path group (the second flow path of the plural), the third here, more about the second flow path _, the third flow The first group of the road c Bu 1 is called the plural pump::===: 122, the flow path for supplying cooling water, and the upper side of the branch group B1 is configured. The first path group B1 is disposed on the downstream side of the first channel A1, and each of the second channels Ma of the one-way group B1 is differentiated from the first channel μ. Thereby, the cooling water is distributed from the first flow path A1, and flows into the respective second flow paths B1a. The first machine path ci is disposed on the downstream side of the second flow path group B1 (i.e., the plurality of second flow paths Bla), and a plurality of second flow paths βι&amp; The cooling water flowing out from each of the second flow paths Bla is collected in the third flow path π, and is discharged in the liquid cooling jacket: 1. The flow path sectional area of the first flow path A1 and the third flow path C1 is set to be larger than the flow path sectional area of the first machine path β 1 a. The flow path length of each of the second flow paths B1a (the length of each of the flat tubes 21) is greatly shortened for one flow path through all the meanders of the portion corresponding to the flat official beam 20 of the related art. 16 201113988 Therefore, the pressure loss caused by the cooling water flowing in the order of the first flow path, the second flow path Bla, and the third flow path hardly occurs - the flow path Ai and the third flow path C1 are The pressure loss of the second flow path βι&amp; for the flow path from the meandering is greatly reduced. Thereby, the rating of the micro pump 122 for supplying the cooling water to the liquid cooling jacket H n can be lowered, and the miniaturization of the micro pump 122 and the noise thereof can be reduced. <cover unit>

As shown in FIG. 7, the cover unit 30 mainly includes a cover body 31, an inlet pipe 32, and a discharge pipe 33. [Cap body] The cap body 3 is attached to and fixed to the sleeve body 10 by the cover body 1 that accommodates the flat tube bundle 2'. In the cover body 3i, the entrance σ31a communicating in the first flow path AU space 1Ga) and the discharge port 31b communicating in the third flow path 空 (space l〇c) are formed (refer to Fig. 7). Further, the cap body 31 has a notch portion 3u which is a notch, and the shape of the notch portion 31c coincides with the position fitting portion 14 of the ferrule body 1A. Thereby, the cover body 31 (the cover unit 3) is formed in a combination with the sleeve and the body 10 only in a predetermined direction. (Inlet port, discharge port) The inlet port 31a and the discharge port 31b are arranged as shown in Fig. 5, and are arranged in a point symmetry with the CPU 101 as a center, and are disposed relatively apart from each other. In other words, the inlet port 31a and the discharge port Wb'CH 1.1 are arranged on the diagonal of the liquid-cooling jacket η which is square in front. In addition, the entrance port 31a is assigned 17 201113988 on the upper left side in Fig. 5, and the other side 'discharge port 31b is arranged on the lower right side in Fig. 5, at the entrance port... and the discharge port 31] The approximate middle position of 3 (presenting the approximate center of the liquid cooling jacket J1), CPU 1〇1 configuration. Therefore, the cooling water from the inlet pipe 32 is supplied to the entire second flow path (the entire second flow path, ...) via the inlet port 31a and the flow path A1'. Further, the entire flow path group W is distributed, and the entire cooling water is efficiently exchanged between the #cpu m. Next, the cooling water flowing out from the plurality of second flow paths Bla is in the third: After the C1 set σ, the tube is discharged through the discharge port 31b', and is discharged to the outside of the liquid to the jacket J1. [Inlet pipe, discharge pipe], and entry into the g 32 are fixed to the cover body 31. In the inlet pipe, the bending softener 124 communicating with the micro-pull 122 (refer to the figure) on the upstream side of the liquid g-ji is connected. Further, the cooling water from the micro-pump 122 passes through the hollow portion of the inlet pipe 32 and the inlet port, and is supplied to the first flow path a&quot; The 'discharge s 33' is fixed to the lid body 31. In the discharge pipe, the soft line communicating with the radiator 121 (refer to the first drawing) on the downstream side of the liquid: the sleeve E J1 is connected, and the cooling water collected in the third flow path C1 is discharged through the row 4 σ 31b. The hollow portion 'of the f 33' is formed to be discharged outside the liquid cooling jacket η. The α inlet S 32 and the discharge pipe 33 are erected on the upper surface side of the lid body 31, and are fixed by the upper side of the liquid cooling jacket ,η, so that the curved hose 18 201113988 124, 124 becomes too Also, in order to connect the inlet pipe 32 and the discharge pipe 33. That is, the personal computer in the restricted space is referred to in Fig. 1), and the processing of the curved hoses 124 and m (refer to the i-th) connected to the liquid cooling jacket is easy. "Effects of liquid cooling jacket" Next, the effect of the liquid cooling jacket η is explained. When the power of the personal computer main body 120 (Fig. 1) is turned on (0N), the cpu un is activated, and the heat starts. Further, the heat of the cpu m is transmitted to the bottom wall u of the casing body 1 through the heat diffusion sheet 102', and is mainly transmitted to the peripheral wall 21b and the partition wall 2ic of the flat tubes 21 constituting the flat tube bundle 20. On the other hand, in conjunction with the power supply of the personal computer body 120, the micro-switch 22 is actuated to cool the water circulation. In this case, in the liquid cooling jacket, the cooling water flows in the order of the first flow path A1, the second flow path group β1 (the plural second flow path B1 a ), and the other flow path C1. Further, heat is exchanged between the peripheral wall 21b of the flat tubes 21 and the partition wall 21c and the cooling water of each of the second flow passages B1a, and is transmitted to the heat of the CPU 1 01 of the peripheral wall 2 J b and the partition wall 21 c. Communicate (move) to the cooling water, which is heated. Then, the cooling water heated by the respective second flow paths B1 a is collected in the third flow path C1, and then discharged through the discharge port 31b and the discharge pipe 33 outside the liquid cooling jacket J1. The discharged cooling water passes through the curved hose 124, and the heat of the cooling water supplied to the radiator 121 in the radiator 121 is released. Further, the cooling water having a lowered temperature is supplied to the liquid cooling jacket J1 after flowing through the microfluid 122 via the reserve tank 123 and the bending hose 124. 19 201113988 Thus, by (1) heat transfer from the CPU 101 toward the heat diffusion sheet 102, the bottom wall 1〇1, the peripheral wall 21b of each flat tube 21, and the partition wall 21c, (2) from the peripheral wall 21b and the partition wall 21c The heat transfer to the cooling water and the heat release of the cooling water in the radiator 121 are continuously performed, and the cpu 1〇1 is efficiently cooled. Further, the heat of the CPU 101 is dispersed and transmitted to the peripheral wall 21b of the plurality of flat tubes 21 and the partition wall 21c, and the heat of the peripheral walls 21]:) and the partition wall 21c is transmitted to the cooling water flowing through the respective second flow paths Bla. The CPU 101 can be cooled efficiently. Further, the cooling water supplied to the liquid cooling jacket J1 is in the liquid cooling jacket gn, and the flow path length is short via the first flow path A1 having a large flow path cross-sectional area, and is mainly distributed as a second of the plurality of heat exchanges. After the flow path Bla (second flow path group B1), the third flow path π set having a large flow path sectional area is discharged, and the pressure loss of the cooling water is reduced in the liquid cooling jacket J1.
