X Electricity 20 [Prior Art] One of the biggest problems with vehicles using petrochemical fuels such as gasoline or diesel is the manufacture of air pollution. The use of secondary batteries (which can be discharged and charged) as a source of power for vehicles has become one of the various methods to solve the above problems. Therefore, electric vehicles (EVs), that is, only use 6 200805736 =:^: 'vehicles, and gas and electricity symbiosis vehicles (cafe "-vehicle =::, some electric vehicles and = for Fanli & Hydrogen (Nl-MH) secondary battery is mainly used as the power source of the two-electrical symbiosis vehicle.

When the battery is used as a power source for electric vehicles and 10 15 electric power and gas-electric symbiosis handles, the two objectives, solid and large capacity, etc., in order to achieve this, constitute a gas-two-inch secondary battery (unit battery) Connected to each other in series or in parallel to form - electric ^ = ' and a plurality of battery modules are connected in parallel or in series with each other. In the secondary battery having high turn-off and large capacity, the single: when the pool is charged or discharged, The heat generated when a large amount of heat is generated is not effectively effective: electricity = heat =: accumulated in the unit cell, causing the unit cell to deteriorate: the plant is a St group needs to have a cooling system, especially when the vehicle battery, And 疋 has back output and large The amount of secondary battery. = Safety ^ When cooling the system, it is necessary to properly consider the point - the second, and - the volume added by the installation of the cooling system is minimized. - General 2::: the formation of the agent flow channel It is necessary to make the coolant be able to move along the surface of the electricity, and can flow through the interior of the battery module to the second: = rate. However, the structure of the coolant flow channel is not complicated; One of the factors that increase the volume of the battery pack. Therefore, a bit of 20 200805736 is formed in the battery module, so that the coolant can be guided and flowed as shown in Fig. 1. Thai: Refer to Figure 1, which is drawn A battery pack cooling system 丨 includes: a 1-cell stack 2' comprising a plurality of batteries; a coolant inlet port 3, a tilt mode I disposed at a lower end of the battery module 2; and a coolant outlet 埠The unit modules 5 are mounted on the upper module 5 of the battery module 2 in an inclined manner. The unit modules 5 are two-=\ and the parent unit module 5 is vertically erected toward one side thereof. 20 each unit group 5 and includes a plurality of electrical connections to each other Secondary electricity: a plurality of gaps are formed between the respective secondary batteries 6 of the unit modules 5, and the coolant flows through the small gaps. Therefore, the coolant introduced by the agent inlet 过3 is supercooled. The heat is generated along the flow path to remove the heat generated by each of the secondary batteries 6. Then, these agents are discharged from the coolant outlet port 4 installed at the upper end of the battery module 2. The battery pack cooling system 1 shown in Fig. 1 has the following problems: The height of the battery pack = 曰 due to the coolant inlet port 3 and the coolant outlet port 4, respectively, the lower end and the upper end of the battery module 2 ~ Plus "the size of some guides. In particular, 'from the coolant inlet 璋3 is opened = gradually decreasing its width, the conduit is installed in the battery module 2, and the d is gradually increased in width toward the coolant outlet 埠4. The module 2 has a square upper portion. Therefore, it is necessary to leave extra space for installing the above-mentioned upper duct and 2 (which includes a plurality of horizontally stacked unit modules 5, and each of the two 5 systems is vertically oriented toward one side thereof) is installed in a vehicle.

冷部系統仍具有下列問題，包括如圖1所示之結構的操作效 率問題。 尤其’經由一冷卻劑進口埠所引入之冷卻劑垂直地撞 25 擊單元模組之外表面或二次電池，接著冷卻劑被引入介於 9 200805736 相對之單元模組之間的冷卻劑流動通道或介於構成每一個 單元模組之二次電池（單元電池）之間的冷卻劑流動通道。由 於冷卻劑垂質地撞擊單元模組之外表面，且接著被引入冷 卻劑流動通道中，因此，有可能藉由形成漩渦的方式改善 5 冷卻效率。然而，在一包括有複數個緊密堆疊之單元模組 (或二次電池）的電池模組中，呈流體形式之冷卻劑的流動會 遭遇到極高的流動阻力。因此，當單元模組（或二次電池） 係以更小的間隙互相堆疊以減少電池組之整體尺寸時，冷 卻劑流動通道便會更窄，便需要設置一冷卻劑流動驅動源 10 (例如一風扇），以產生提升冷卻劑流動速度所需要的驅動 力。

—此關係將參照圖2而進行料，圖2繪示了本發明一較 佳^施例之電池模組。請參照圖2，—電池模組2q包括了 X 個單元模組10。假設每一個單元模組之長度為a、每一個單 元模組之覓度為b、每一個單元模組之厚度為c，則為了達 成f輸出與大容量，此電池模組需要將這些單元模組相互 堆豐，使得此電池模組的側邊長度滿足下列不等式： X。在此實施例中，此電池模組之長邊的長度為以乂。 根據本發明，冷卻劑進口埠係位於外殼構件之一側、 且平行於那些設置於各單元模組之間的間隙（位於單元模 組之間），且此冷卻劑進口埠係形成於一對應於電池模組之 長邊（CXX)的位置上。 20 此結構提供了多種效果。首先，當冷卻劑被引入那些 介於各單元模組之間垂直流動通道時所產生的流動阻力 (flow resistance)會減低，進而提升本發明之電池模組的冷 卻效率。再者，介於「冷卻劑進口谭」以及「每一個垂直 流動通道之相距冷卻劑進口埠最遠部分」之間的距離亦縮 25 短，進而提升本發明之電池模組的冷卻均勻性。最後，冷 13 200805736 卻劑進口埠的形狀係為一系列對應於電池模组長邊之長戶 的貫孔’因此本發明之電池組僅需要微小驅動 ^ 冷卻劑流動。 ： 10 15 20 與前述之第-個效應有關的是，前述之通過那些設置 於外殼構件之長邊的冷卻劑進口埠而水平引進之冷卻劑合 自然地被引人垂直流動通道（即位於各單元模組之間的& 隙）中’且這些垂直流動通道係以—與冷卻劑引人方向平行 之方向被設置。因在匕，流動阻力可大幅降低。巨觀而古， 冷卻劑係垂直地流經各電池模組。另—方面，微觀而二 此冷卻劑的流動梯度（flowlng gradien⑽則自冷卻劑ς 口 埠開始逐漸地降低。因此，冷卻劑的流動阻力降低了，且 即便應用較小的驅動力，本發明之電池組仍具有最大化 冷卻效率。 與—前述之第二個效應有關的是，介於「冷卻劑進口埠」 以及母個垂直⑽動通道之相距冷卻劑進口埠最遠部分 之間的距離係受限於每—個單元模組的長度a。因此，相較 於習^電池模組中之介於「冷卻劑進口槔」以&「每一個 垂直流動通道」之間的距離會隨著電池模組之長邊的長度 而^力本赍明之電池組之介於「冷卻劑進口璋」以及「每

regard, Japanese Patent Application Laid-Open No. 2004-223171, and Korean Patent Application Publication No. PCT-A No. 355-35478 disclose the cooling of the medium-sized group, which is characterized in that the battery module is The clothing is again in the outer casing of the babies, and the battery module itself is inclined at a predetermined angle so that the need for a separate conduit can be used to form the cooling and flow passages required for the introduction and discharge of the coolant. In the meantime, Japanese Patent Application Publication No. 2-4-22317 discloses a technique of mounting a plurality of unit cells in a small-sized battery module, and tilting the unit cells at a predetermined angle to form a "coolant flow. In the disclosed cooling system, a preferred = portion of the flow channel is formed to maximize the internal space of the battery pack housing and the battery module is mounted on the outer casing of the battery module. The cooling system disclosed in Japanese Laid-Open Patent Publication No. 2004-223-17 proposes the possibility of manufacturing a battery pack having a smaller size of the catheter structure as shown in Fig. 1. However, the patent application publication is hereby incorporated by reference. The cold section system disclosed in No. 2004-223 17 still has the following problems, including the operational efficiency problem of the structure as shown in Fig. 1. In particular, the coolant introduced through a coolant inlet port vertically hits 25 unit modules. The outer surface of the group or the secondary battery, and then the coolant is introduced into the coolant flow channel between the unit modules of 9 200805736 or between the two modules a coolant flow path between the cells (cell cells). Since the coolant impinges on the outer surface of the unit module and is then introduced into the coolant flow path, it is possible to improve the cooling efficiency by forming a vortex. However, in a battery module including a plurality of closely stacked unit modules (or secondary batteries), the flow of the coolant in fluid form encounters extremely high flow resistance. Therefore, when the unit module (or secondary battery) When the stack is stacked with each other to reduce the overall size of the battery pack, the coolant flow path is narrower, and a coolant flow drive source 10 (for example, a fan) is required to generate The driving force required to increase the coolant flow rate. At the same time, the coolant inlet enthalpy is formed in the unit module (or secondary battery) ^ shaft = direction. When a medium or large size battery pack is composed When the unit cells (or secondary batteries) are stacked on each other to provide high rotation and 15 power, the width of the battery module is greater than the length of each unit module. The cold section inhomogeneity of the group is quite clear. In particular, the amount of coolant introduced into the unit module (or the two pools) closest to the coolant inlet port is less than The amount of coolant introduced into a single-turn module (or secondary battery) that is farthest from the coolant inlet port. Therefore, the battery, the cooling unevenness is extremely high, and the above has high flow resistance. In the construction of the scholars, this problem is even more serious. Therefore, the industry needs a technology to basically solve the above problems. [Invention] The present invention is a technical problem to be solved by the present invention. In addition, one of the objects of the present invention is to assemble a battery module in an external component, a "pool group, and its constituent structure - a predetermined angle is inclined, thereby forming a battery module for the outer casing. The component and the battery module are rented in a gap between the shell member and the battery module under the gap between the shell member and the battery module, and a gap between the electric, and also the right side of the outer invention. Therefore, the Department η has a compact structure' and its height is not increased at the same time due to the grasping of cold heading structures (such as ducts). Another purpose of the present invention is that the gap between the constituent units of each unit module pool group is introduced into a 1520 agent by a parallel coolant can be effectively provided to Battery invention: The skin is supplied to various parts of the battery module, so that the power/, and the up efficiency and the cooling uniformity can be improved. The battery pack constituting the in:;:: provides a battery pack whose structural structure is such that the battery of the moon: the two-end frame conforms to the internal junction of the vehicle x can be stably disposed in the vehicle. Dimensional Electricity = This "Month", the above-mentioned purposes can be achieved by a size or large 曰 == core, which includes a plurality of horizontally stacked unit modules, which are vertically oriented toward one side thereof. One of the battery module outer casing members is in a closed space; wherein the outer casing or the lower end is provided with a coolant inlet port, and the outer casing member is provided with a coolant at a lower end or an upper end of the opposite side The outlet module is mounted in the outer casing member such that the upper end surface or the lower end surface of the battery module is inclined at a predetermined angle toward the coolant inlet port 11 25 200805736, whereby a coolant is used as a The parallel direction of the battery module is introduced by the coolant inlet port, such that the coolant passes vertically through the unit modules and is then discharged from the opposite side; and a plurality of gaps (vertical flow channels), the gaps are It is defined between the unit modules of the upper end surface or the lower end surface of the tilting of the battery module, and the gaps are arranged parallel to the direction in which the coolant is introduced. As described above, the battery pack of the present invention comprises a battery module including a plurality of unit modules electrically connected to each other, or two or more battery modules, wherein the battery modules are disposed in one In the outer casing member. 10 15 20 Each saponin module can be a battery unit that can be charged and discharged, or a battery unit that contains two or more battery units. In the present specification, '"electrically connected" and "combined" means that the upper or lower end of the single-turn module or the battery unit case member is connected in series and/or in parallel with each other in parallel with the gap (five) straight flow passage). In order to provide a battery pack having an ideal transmission 2 and an electric valley, it is preferably a high output and a large capacitance. For example, each of the battery cells includes a cathode, an anode, a separator membrane, and an electrolysis bakelite, and each of the battery cells is disposed in a sealed container, so that each cell unit can be charged and discharged. Preferably, each of the battery cells may be a battery soap cell, a lithium ion polymer battery cell, or a nickel-hydrogen battery. The coolant inlet port is formed in the outer casing. The upper or lower end is then 'and parallel to those gaps (vertical flow channels) that are placed between the slopes of each group, as described above. The port is formed on the long side of the medium or large size battery module. The battery module includes a plurality of unit modules stacked on each other. 12 25 200805736 3 The length of the arsenic arsenic of several unit modules is limited by the number of unit modules used: = long assumes that multiple uses square shape;: and: unit module The length of a, each _ _ _ / /, the mother of a early element module, the thickness of the scorpion μ loose is b, each single,,: one e, ^ the number of unit modules used is x, A battery module consisting of a group of * 扪 扪 紧密 紧密 紧密 紧密 且 且 且 且 且 且 且 且 , , , , , , , , , , , , , , , , , , , , , , , , , , For a and cxx, the height is b. 10 15 - This relationship will be studied with reference to Fig. 2, which shows a battery module of a preferred embodiment of the present invention. Referring to FIG. 2, the battery module 2q includes X unit modules 10. Assuming that the length of each unit module is a, the strength of each unit module is b, and the thickness of each unit module is c, in order to achieve f output and large capacity, the battery module needs to be used for these unit modules. The groups are piled up to each other such that the side length of the battery module satisfies the following inequality: X. In this embodiment, the length of the long side of the battery module is 乂. According to the present invention, the coolant inlet is located on one side of the outer casing member and parallel to the gaps (between the unit modules) disposed between the unit modules, and the coolant inlet is formed in a corresponding On the long side (CXX) of the battery module. 20 This structure provides a variety of effects. First, the flow resistance generated when the coolant is introduced into the vertical flow passages between the unit modules is reduced, thereby improving the cooling efficiency of the battery module of the present invention. Furthermore, the distance between the "coolant inlet tan" and the "the farthest portion of each of the vertical flow passages from the coolant inlet" is also shortened by 25, thereby improving the cooling uniformity of the battery module of the present invention. Finally, the shape of the cold inlet 13 200805736 is a series of through holes corresponding to the long sides of the battery module. Therefore, the battery pack of the present invention requires only a small drive ^ coolant flow. : 10 15 20 In connection with the first effect described above, the aforementioned coolant introduced horizontally through the coolant inlet ports provided on the long side of the outer casing member is naturally introduced into the vertical flow passage (ie, located at each In the & gap between the unit modules, and these vertical flow channels are arranged in a direction parallel to the direction in which the coolant is directed. Because of the sputum, the flow resistance can be greatly reduced. Giant and ancient, the coolant flows vertically through each battery module. On the other hand, the microscopic flow gradient of the coolant (flowlng gradien (10) gradually decreases from the coolant enthalpy. Therefore, the flow resistance of the coolant is lowered, and even if a small driving force is applied, the present invention The battery pack still has the greatest cooling efficiency. In relation to the second effect described above, the distance between the "coolant inlet port" and the parent vertical (10) moving channel from the farthest part of the coolant inlet port is Limited by the length a of each unit module. Therefore, the distance between the "coolant inlet port" and the "every vertical flow channel" will be the same as in the battery module. The length of the long side of the battery module and the battery pack between the "coolant inlet port" and "the farthest portion of each vertical flow channel from the coolant inlet port" #微. Therefore, the battery pack of the present invention can greatly reduce the cooling unevenness of the farthest portion of the coolant inlet port in the parent-vertical flow channel. / Related to: the third effect described above, One of the series of coolant inlets has increased the amount of coolant that can be introduced in a unit of time. 14 25 200805736 Therefore, only a small battery pack of the 驴 士 μ μ 亦 亦 亦 亦 亦 亦 亦 亦 亦 。 。 。 。 。 。 。 。 。 。 。 Two sides; the upper end of the outer casing member faces the fine surface above the battery module. However, in this embodiment, it must be avoided to increase to ensure that - the structure of the outer casing is two or two. It is not a preferred structure. !〇15 2〇(4)^地'冷部剂^ The 埠 system is formed in the same phase as the coolant inlet 四 phase (4), 'so that the coolant introduced through the coolant inlet 可以 can pass 7C each morning After the module is discharged, for example, the coolant inlet port may be formed in the vicinity of the upper end edge of the outer casing member - (d), and its shape is: a series of through holes, and the coolant outlet port may be formed in Further, at least one side of the lower end of the shell member. In more detail, when the coolant inlet raft is formed on the left side of the upper end of the 2 shell member, the coolant outlet port may be formed on the right side of the lower end of the member, or Shell member The opposite sides of the lower end are such that the outlets of the chilling agent are parallel to each other. Here, the side edges of the outer casing member provided with the coolant inlet 埠 and the cold agent outlet 可 may vary depending on the direction in which the battery module is tilted. For example, when both the coolant inlet port and the coolant outlet port are formed on the left side of the outer casing member, the battery module is disposed in such a manner that the upper end of the battery module is inclined toward the left side of the outer casing member. Preferably, a cooling fan (blowing fan) is installed at the coolant outlet port to generate a driving force required to drive the coolant to flow. Preferably, the battery module is at an angle of between 1 and 4 degrees. Tilt. When the tilt angle of the 25 battery module is too small, the size of the coolant inlet port will be reduced by 15 200805736, making it difficult to increase the other time in the unit time.

The outer casing member 40 is attached to the frame 3〇 so that the outer casing member is disposed around the battery module. By the support portions 33, 34 of the frame 30 having different heights and protruding upwards, the battery module 2 is tilted toward the coolant inlet 以 at a predetermined angle. Therefore, the outer casing member 4 〇 and the battery module 2) The upper surface of the phantom 20 door & gap is inclined, and the gap between the outer casing member 40 and the lower end surface 22 of the battery module 20 is also inclined. Thus, the tilt of the battery module is naturally formed. a coolant flow channel. The coolant introduced by the coolant inlet port is along the gap (these gaps are located between the unit modules 1〇, and the direction is opposite to the direction in which the coolant is introduced Parallel) flow, that is, flow along vertical flow channel 26 200805736 "The coolant is then discharged via a coolant outlet port (not shown). Therefore, the large flow that occurs in the structure shown in Figure 1 The resistance does not occur when the cooling is introduced into the vertical flow passage 26. Thus, the cooling efficiency of the battery pack of the present invention is improved. Therefore, as shown in Fig. 3, the coolant is gently inclined along the vertical direction. At the same time, since the coolant inlet port 45 is formed on the left side of the outer casing member 4〇 and parallel to the vertical flow channel 26, the "coolant inlet port 45" and "each vertical flow" The distance between the passages 26 and the farthest portion A" of the coolant inlet 会 is limited by the length of each unit module 1 〇 10. Therefore, the battery pack of the present invention can greatly reduce the cooling unevenness, wherein the cooling unevenness is caused by the "coolant inlet port 45" and the "the farthest portion of each vertical flow channel from the coolant inlet port" the distance.

The scope and spirit of the description. INDUSTRIAL APPLICABILITY As described above, it is apparent that the structure of the battery pack of the present invention is that the battery module is assembled in an outer casing member such that the battery module is inclined at a predetermined angle to be interposed between the outer casing members. The gap with the upper end surface of the battery module and the gap between the outer casing member and the lower end surface of the battery module form a naturally inclined flow passage. Therefore, the battery of the present invention 18 200805736, and having a structure of compaction, does not increase its twist due to the arrangement of the cooling structure. Further, the gap (vertical flow passage) between the unit modules is parallel to the direction in which the cold refrigerant is introduced, so that the coolant can be efficiently supplied to the battery module. On the other hand, the distance between the "coolant inlet port" 5 and the parent vertical flow channel 26 from the most distant portion of the coolant inlet port is limited by the length of each unit module. Therefore, the battery pack of the present invention can uniformly supply the coolant to the respective portions of the battery module', thereby improving the cooling uniformity of the battery pack of the present invention. At the same time, the battery pack of the present invention can be modified so that the outer 10 type of the frame constituting the lower end thereof conforms to the internal structure of a vehicle. Therefore, the battery pack of the present invention can be more stably installed in a vehicle.
