在再生能源日益風行的社會中,將用電離峰時間所產生的多餘電力儲存起來,於用電尖峰時間再釋放出來成為大量採用再生能源的一大課題。而儲電最直接的方式即為使用充電電池組;唯充電電池組在充放電時會釋放熱量,若置之不理將因升溫而大幅減少充電電池組的壽命,甚或發生安全問題;且若是要儲存大量電力勢必要使用大量的充電電池組,所有不同位置的充電電池組之間如何能均勻的散熱進而阻止特定位置的充電電池組先行失效,便成為各單位研究的對象。 In a society where renewable energy is becoming more and more popular, storing the excess electricity generated during the peak ionization time and releasing it during the peak time has become a major issue in the massive use of renewable energy. The most direct way to store electricity is to use rechargeable battery packs; only rechargeable battery packs will release heat during charging and discharging. If ignored, the life of the rechargeable battery pack will be greatly reduced due to the temperature rise, or safety problems may occur; and if a large amount of storage is required Electricity is bound to use a large number of rechargeable battery packs. How to dissipate heat evenly among all the rechargeable battery packs in different locations to prevent the rechargeable battery packs in specific locations from failing first has become the object of research by various units.
習知方法如我國專利申請案號第107145070號「電池溫度控制裝置和方法、控制器、儲存介質和充換電站」中所揭示,針對個別的電池分別安裝個別對應的冷媒循環系統,但若應用在大數量的電池系統中,勢必面臨管線裝配的複雜化問題以及大量獨立循環系統所帶來較高的成本。 The conventional method is disclosed in my country Patent Application No. 107145070 "Battery Temperature Control Device and Method, Controller, Storage Medium, and Charging and Swap Station".

又如我國專利申請案號第103112870號「用於電池單元間平均分佈溫度的系統」中所揭示,將多數電池同時設置於一個大循環槽之內,以槽內循環的導熱流體來將各電池的溫度平均化,但是各電池在循環槽中的不同位置時所得到的散熱效果終究不會相同,案中也並未揭示相關的設計要點;且將大量電池集中在單一槽體之內,在槽體內的個別電池需要維修時也會面臨大量電池同時離線的問題。As disclosed in China's Patent Application No. 103112870 "System for Evenly Distributing Temperature Between Battery Cells", a large number of batteries are placed in a large circulation tank at the same time, and the heat transfer fluid circulating in the tank is used to transfer each battery The temperature is averaged, but the heat dissipation effect obtained when the batteries are in different positions in the circulation tank will not be the same after all, and the relevant design points are not disclosed in the case; and a large number of batteries are concentrated in a single tank. When individual batteries in the tank need to be repaired, they also face the problem of a large number of batteries being offline at the same time.
有鑑於此,本發明人乃潛心研思、設計組製,期能提供一種可減少成本但仍保持平均化功效的儲能散熱系統,即為本發明所欲研創之發明動機者。In view of this, the inventors devote themselves to research and design, and hope to provide an energy storage and heat dissipation system that can reduce costs but still maintain an average efficiency.

循環散熱模組包含一循環泵、一控制單元及一散熱單元,散熱單元包含一冷排及一風扇,控制單元電性連接循環泵、風扇、第一電力模組及第二電力模組,循環泵之一端連接冷排,循環泵之另一端連接進液管,冷排之另一端連接排液管。散熱流體充填於第一電力模組、第二電力模組、進液管、排液管及循環散熱模組之中,散熱流體受循環泵推動而循環流動。控制單元可控制循環泵的流速及第一、第二電力模組的電力輸出。The circulating heat dissipation module includes a circulating pump, a control unit and a heat dissipation unit. The heat dissipation unit includes a cold row and a fan. The control unit is electrically connected to the circulating pump, the fan, the first power module and the second power module to circulate One end of the pump is connected to the cold row, the other end of the circulating pump is connected to the liquid inlet pipe, and the other end of the cold row is connected to the liquid discharge pipe. The heat dissipation fluid is filled in the first power module, the second power module, the liquid inlet pipe, the liquid discharge pipe and the circulating heat dissipation module, and the heat dissipation fluid is driven by the circulating pump to circulate. The control unit can control the flow rate of the circulating pump and the power output of the first and second power modules.
散熱流體由循環泵流出進入進液管,再往第一及第二電力模組移動時,由於第一電力模組在第一進液分支管上的連結位置位於第二電力模組連結位置的前方,散熱流體會先流入第一電力模組再流入第二電力模組;但在連結排液管時,第一電力模組在第一排液分支管上的連結位置位於第二電力模組連結位置的後方,第二電力模組流出的散熱流體會較第一電力模組的更早離開,藉此達成散熱流體先流進第一電力模組但是較晚流出第一電力模組,意即「先進後出」的狀態,讓同一循環系統內的第一電力模組及第二電力模組可以得到均等的散熱效果。散熱流體帶走第一及第二電力模組的熱量後,再由排液管流到散熱單元降溫後再重複循環。如此一來就不用分別獨立管理第一及第二電力模組之散熱流體流量,又可以使雙方的散熱效果平均化。When the heat dissipation fluid flows out of the circulating pump into the liquid inlet pipe, and then moves to the first and second power modules, because the connection position of the first power module on the first liquid inlet branch pipe is located at the connection position of the second power module In the front, the heat dissipation fluid will first flow into the first power module and then into the second power module; but when the drain pipe is connected, the connection position of the first power module on the first drain branch pipe is located in the second power module Behind the connection position, the heat dissipation fluid flowing out of the second power module will leave earlier than the first power module, so that the heat dissipation fluid flows into the first power module first but flows out of the first power module later, meaning That is, the "first-in-last-out" state allows the first power module and the second power module in the same circulatory system to get an equal heat dissipation effect. After the heat dissipating fluid takes away the heat of the first and second power modules, it flows from the drain pipe to the heat dissipating unit to cool down and then repeats the cycle. In this way, there is no need to independently manage the heat dissipation fluid flow of the first and second power modules, and the heat dissipation effects of both can be evened.
由於第一及第二電力模組內皆分別有一熱感測元件並連接到控制單元,若是各電力模組因為輸出電力導致內部溫度上升時,控制單元便可以加大散熱流體的流量加速散熱;電力輸出降低時則可減少散熱流體之流量。進液管與排液管亦可加裝熱感測元件,讓控制單元可藉由量測進排液的溫差來控制循環散熱模組之散熱流體流量。Since the first and second power modules each have a thermal sensing element and are connected to the control unit, if the internal temperature of each power module rises due to the output power, the control unit can increase the flow rate of the heat dissipation fluid to accelerate heat dissipation; When the power output is reduced, the flow of the cooling fluid can be reduced. The liquid inlet pipe and the liquid discharge pipe can also be equipped with thermal sensing elements, so that the control unit can control the heat dissipation fluid flow of the circulating heat dissipation module by measuring the temperature difference of the liquid inlet and discharge.
本發明可以簡單地擴充總電力容量,例如增加一第三電力模組及一第四電力模組,進液管增加一第二進液分支管在第一進液分支管之後,排液管增加一第二排液分支管在第一排液分支管之前,再將第三電力模組及第四電力模組同樣遵循「先進後出」的原則連接於第二進液分支管及第二排液分支管,如此一來散熱流體會先流進第一進液分支管再流進第二進液分支管,然後第二排液分支管的散熱流體較第一排液分支管的散熱流體先離開,依然可以達到散熱能力的平均化。The present invention can simply expand the total power capacity, such as adding a third power module and a fourth power module, adding a second liquid inlet branch pipe to the liquid inlet pipe, and adding a liquid discharge pipe after the first liquid inlet branch pipe. A second discharge branch pipe is before the first discharge branch pipe, and then the third power module and the fourth power module are connected to the second inlet branch pipe and the second row according to the principle of "first in, last out". The liquid branch pipe, so that the heat dissipation fluid will first flow into the first liquid inlet branch pipe and then into the second liquid inlet branch pipe, and then the heat dissipation fluid of the second liquid discharge branch pipe will be earlier than the heat dissipation fluid of the first liquid discharge branch pipe. Without leaving, the average heat dissipation capacity can still be achieved.
第一進液分支管、第二進液分支管、第一排液分支管及第二排液分支管可分別有一電性連接控制單元的流量閥,若有其中一組電力模組溫度較高時,控制單元可將散熱流體之流量集中於某一組進液分支管及排液分支管加強散熱;或是在個別電力模組需要維修時切斷其中一組進液分支管及排液分支管的流量方便維修,無須將全部的電力模組同時從控制單元斷開。The first liquid inlet branch pipe, the second liquid inlet branch pipe, the first liquid discharge branch pipe and the second liquid discharge branch pipe can each have a flow valve electrically connected to the control unit. If one of the power modules has a higher temperature The control unit can concentrate the flow of the heat-dissipating fluid on a certain group of inlet branch pipes and discharge branch pipes to enhance heat dissipation; or cut off one group of inlet branch pipes and discharge branches when individual power modules need to be repaired The flow of the tube is convenient for maintenance, and it is not necessary to disconnect all the power modules from the control unit at the same time.
又,可以增加單一組進液及排液分支管所連接的電力模組數量來增加總電力容量,例如增加一第五電力模組於第一電力模組與第二電力模組之間,讓原本串接兩電力模組的分支管增加為串接三電力模組,但第一、第五及第二電力模組之間的散熱流體循環關係同樣遵循「先進後出」的原則,故同一組進液及排液分支管的第一、第五及第二電力模組仍然能得到平均分配的散熱流體流量。In addition, the number of power modules connected to a single set of liquid inlet and discharge branch pipes can be increased to increase the total power capacity. For example, a fifth power module can be added between the first power module and the second power module to allow The branch pipe that originally connected two power modules in series was increased to three power modules in series, but the circulation relationship of the heat dissipation fluid between the first, fifth and second power modules also follows the principle of "first in, last out", so the same The first, fifth, and second power modules of the liquid inlet and liquid discharge branch pipes can still get an evenly distributed flow of heat dissipation fluid.

本發明之實施例(一)運作時,散熱流體(未繪製)由循環泵5前往進液管3,再往第一電力模組1及第二電力模組2所連接的第一進液分支管31移動,由於第一電力模組1之第一進液孔101及第二電力模組2之第二進液孔201皆連結於在第一進液分支管31上,且第一進液孔101連結的第一裝置給液口311位於第二進液孔201連結的第二裝置給液口312之前方,散熱流體(未繪製)會先由第一裝置給液口311流入第一電力模組1,再由第二裝置給液口312流入第二電力模組2;而在連結排液管4時,由於第一電力模組1之第一排液孔102及第二電力模組2之第二排液孔202皆連結於在第一排液分支管41上,且第一排液孔102連結的第二裝置排液口411位於第二進液孔201連結的第一裝置排液口412之後方,由第二電力模組2流出的散熱流體(未繪製) 會先由第一裝置排液口412流入排液管4,第一電力模組1流出的散熱流體(未繪製)會較慢由第二裝置排液口411流入排液管4。When the embodiment (1) of the present invention is in operation, the heat dissipation fluid (not shown) flows from the circulating

如此一來,本發明之實施例(二)運作時,散熱流體(未繪製)由循環泵5流出進入進液管3,再往第一進液分支管31及第二進液分支管32移動,由於進液管3為由下往上方延伸,第一進液分支管31位於較該第二進液分支管32前端的位置,散熱流體(未繪製)會先進入第一進液分支管31並透過第一裝置給液口311及第二裝置給液口312分配給第一電力模組1及第二電力模組2,散熱流體(未繪製)再進入第二進液分支管32並透過第三裝置給液口321及第四裝置給液口322分配給第三電力模組6及第四電力模組7,並先流入第三電力模組6再流入第四電力模組7。In this way, when the embodiment (2) of the present invention is in operation, the heat dissipation fluid (not shown) flows out of the circulating

實施例(三)中第一電力模組1、第五電力模組8及第二電力模組2並列在第一進液分支管31及第一排液分支管41之上,故進液順序為第一電力模組1à第五電力模組8à第二電力模組2,排液順序則是第二電力模組2à第五電力模組8à第一電力模組1,同樣保持在「先進後出」的狀態,第一電力模組1、第五電力模組8及第二電力模組2之間的散熱流體(未繪製)之流量依然可以達到平均化。In the third embodiment, the
