Description

Technical Field

[0001] This utility model belongs to the field of energy storage battery technology, and in particular, relates to a cooling and heat dissipation system and a flow battery system. Background Technology

[0002] A flow battery consists of a stack unit, electrolyte, electrolyte storage and supply unit, and management and control unit. Currently, most flow batteries used for energy storage in large power plants employ a common structure with electrolyte, reaction tank, and circulating pump, and are equipped with a cooling mechanism to control the stack reaction temperature, enabling the flow battery to store energy smoothly.

[0003] However, during the chemical reaction process in a flow battery, heat is generated in the stack. The amount of heat generated in the stack varies with the input of electrolyte and other components. This is especially true for test stacks, where test conditions are variable and the amount of heat generated varies greatly. Since the coolant flow rate of the cooling system is usually fixed, the coolant flow rate cannot be adaptively adjusted according to the actual heat generation of the stack. This can easily lead to a mismatch between the coolant flow rate supplied by the cooling system and the amount of heat generated by the stack. When the heat generated in the stack is large, the cooling efficiency is low and the cooling effect is poor, making it difficult to quickly and efficiently control the reaction temperature within the preset temperature range. Conversely, when the heat generated by the stack is small, it can lead to unnecessary energy waste in the cooling system, which increases the operating cost of the flow battery to some extent.

Therefore, the phrases "in one embodiment", "in some embodiments", or "in some embodiments" appearing in various places throughout the specification are not all referring to the same embodiment. In addition, in one or more embodiments, specific features, structures, or characteristics can be combined in any suitable manner.

[0038] Please refer to Figures 1 to 5The cooling and heat dissipation system provided by the embodiment of the utility model is described as follows: the cooling and heat dissipation system comprises a heat dissipation assembly 2, a circulating assembly 3 and a flow regulating valve 4. The heat dissipation assembly 2 is arranged on the reaction container 1, such as the two side surfaces of the reaction container 1. The heat dissipation assembly 2 is arranged on the reaction container 1 and can cool and dissipate heat of the reaction container 1, so as to take away the heat generated by the chemical reaction in the reaction container 1 and prevent the temperature in the reaction container 1 from being too high to be unfavorable for the chemical reaction of the flow battery. The reaction container 1 can be, but is not limited to, a reaction container or a reaction box, such as a stack, which can be used for the chemical reaction of the flow battery. The circulating assembly 3 comprises a refrigeration circulator 31, a liquid conveying pipeline 32 and a liquid returning pipeline 33. The liquid conveying pipeline 32 connects the liquid outlet port of the refrigeration circulator 31 and the liquid inlet port 231 of the heat dissipation assembly 2, and the liquid returning pipeline 33 connects the liquid returning port of the refrigeration circulator 31 and the liquid outlet port 241 of the heat dissipation assembly 2. The refrigeration circulator 31 comprises a refrigeration box 311 and a circulating machine 312 arranged on the refrigeration box 311. The cooling liquid in the refrigeration box 311 is drawn out by the circulating machine 312, and the drawn-out cooling liquid is conveyed to the heat dissipation assembly 2 through the liquid conveying pipeline 32. The cooling liquid flowing through the heat dissipation assembly 2 is heated and has a temperature rise. The cooling liquid with the temperature rise is returned to the refrigeration box 311 through the liquid returning pipeline 33. The refrigeration box 311 is used for cooling the cooling liquid with the temperature rise, so that the temperature of the cooling liquid is reduced to a preset temperature range. The cooling liquid in the refrigeration box 311 is drawn out to the heat dissipation assembly 2 by the circulating machine 312. The self-circulation of the cooling liquid is performed in this way. The heat generated by the chemical reaction in the reaction container 1 can be taken away by the cooling liquid, so that the temperature in the reaction container 1 is effectively controlled. In addition, the flow regulating valve 4 is arranged on the liquid conveying pipeline 32. Since the flow regulating valve 4 can adjust and control the flow of the cooling liquid conveyed by the liquid conveying pipeline 32 to the heat dissipation assembly 2, the flow of the cooling liquid conveyed by the liquid conveying pipeline 32 to the heat dissipation assembly 2 can be adaptively adjusted according to the actual situation of the heat generated by the chemical reaction of the flow battery in the reaction container 1, so that the flow of the cooling liquid supplied by the circulating assembly 3 matches the heat generated by the chemical reaction of the flow battery. Specifically, when the heat generated in the reaction container 1 is large, the flow regulating valve 4 is adjusted and controlled to increase the flow of the cooling liquid conveyed by the liquid conveying pipeline 32 to the heat dissipation assembly 2, so that the cooling efficiency of the cooling liquid on the reaction container 1 is low and the cooling effect is poor, and the temperature in the reaction container 1 is quickly and efficiently adjusted and controlled in the preset temperature range. When the heat generated in the reaction container 1 is small, the flow regulating valve 4 is adjusted and controlled to reduce the flow of the cooling liquid conveyed by the liquid conveying pipeline 32 to the heat dissipation assembly 2, so as to avoid unnecessary energy waste and reduce the use cost of the flow battery to a certain extent.

[0039] Compared with the prior art, the cooling and heat dissipation system has the following advantages: the heat dissipation assembly 2 is arranged on the reaction container 1 and can cool and dissipate heat of the reaction container 1; the outlet port of the refrigeration circulator is communicated with the inlet port 231 of the heat dissipation assembly 2 through the liquid conveying pipeline 32; the return liquid port of the refrigeration circulator 31 is communicated with the outlet port 241 of the heat dissipation assembly 2 through the liquid return pipeline 33; the refrigeration circulator 31 can provide self-circulation power for the cooling liquid, so that the cooling liquid flowing through the heat dissipation assembly 2 can continuously take away the heat generated in the reaction container 1, thereby achieving the purpose of effectively controlling the temperature in the reaction container 1.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the flow regulating valve 4 comprises a valve body 41 provided with a flow regulating hole 412 and a valve cavity 411, a sliding member 42 slidingly arranged in the valve cavity 411, a flow regulating member 43 arranged on the sliding member 42 and matched with the flow regulating hole 412, and a driving mechanism 44 driving the sliding member 42 to slide. The valve body 41 has a columnar structure, and the cross-sectional shape of the valve body 41 can be circular or elliptical, or square, pentagonal, hexagonal or other polygonal. The valve body 41 is connected to the liquid conveying pipeline 32. When the driving mechanism 44 drives the sliding member 42 to move linearly between the first position and the second position, the sliding member 42 can drive the flow regulating member 43 to approach or move away from the flow regulating hole 412, and the gap between the flow regulating member 43 and the flow regulating hole 412 changes with the movement of the position of the flow regulating member 43, thereby achieving the purpose of regulating the flow of the cooling liquid and realizing the adjustment of the cooling efficiency of the cooling liquid on the reaction container 1. It should be noted that when the driving mechanism 44 drives the sliding member 42 to stay at the first position, the sliding member 42 can drive the flow regulating member 43 to completely block and close the flow regulating hole 412, thereby blocking the flow of the cooling liquid; when the driving mechanism 44 drives the sliding member 42 to stay at the second position, the sliding member 42 can drive the flow regulating member 43 to completely open the flow regulating hole 412. The flow regulating valve 4 provided in the embodiment can solve the problem that the flow regulating function of the existing electromagnetic valve is limited.

[0041] Please refer to Figure 2In some embodiments, the flow regulating member 43 is a sealing plug with a trapezoidal or triangular cross section. During the process of moving the flow regulating member 43 towards or away from the flow regulating hole 412 by the sliding member 42, the gap between the flow regulating member 43 and the flow regulating hole 412 changes with the position of the flow regulating member 43, so as to adjust the flow rate of the coolant.

[0042] For reference, please see Figure 2 and Figure 3 In some embodiments, the sliding member 42 is a sliding rack arranged in the valve cavity 411, the valve body 41 is provided with a threaded hole communicating with the valve cavity 411, the drive mechanism 44 comprises a transmission gear 441 arranged in rotation in the valve cavity 411, a transmission screw 442 threadedly connected in the threaded hole, a transmission rack 443 connected to the end of the transmission screw 442 extending into the valve cavity 411, and a drive motor 444 driving the transmission screw 442 to rotate, the drive motor 444 being connected to the end of the transmission screw 442 extending outside the valve cavity 411, the sliding rack and the transmission rack 443 being engaged with the transmission gear 441 respectively. In this embodiment, the drive motor 444 drives the transmission screw 442 to rotate, the transmission screw 442 moves along its axial direction under the cooperation of the threads of the threaded hole, the transmission screw 442 drives the transmission rack 443 to move in a first direction during the movement, the transmission rack 443 drives the transmission gear 441 to rotate, and the transmission gear 441 further drives the sliding rack to move in a second direction, so as to drive the flow regulating member 43 to move towards or away from the flow regulating hole 412 by the sliding rack, so that the gap between the flow regulating member 43 and the flow regulating hole 412 changes with the position of the flow regulating member 43, so as to adjust the flow rate of the coolant. In addition, it should be noted that the first direction is perpendicular to the second direction, the second direction is parallel to the axial direction of the flow regulating hole 412, and the axial direction of the transmission screw 442 is perpendicular to the axial direction of the flow regulating hole 412. Through the conversion of the vertical movement of the transmission screw 442 into the horizontal movement of the sliding rack under the linkage of the transmission rack 443 and the transmission gear 441, on the one hand, the structure of the flow regulating valve 4 can be made more simple and compact, which is conducive to reducing the volume of the flow regulating valve 4, and on the other hand, the accuracy, sensitivity and stability of the flow regulating valve 4 can be improved.

[0043] For reference, please see Figure 2 In some embodiments, the drive mechanism 44 further comprises a support slide 445 arranged on the valve body 41, the output shaft of the drive motor 444 is coaxially connected to the transmission screw 442, and the drive motor 444 is arranged on the support slide 445 in a sliding manner along the axial direction of the transmission screw 442. During the process of driving the transmission screw 442 to rotate by the drive motor 444, the drive motor 444 moves with the transmission screw 442. It should be noted that the drive motor 444 can be but is not limited to a speed reducer.

[0044] Please refer to Figure 3 In some embodiments, at least one guide plate 446 is arranged on the transmission rack 443, and a corresponding guide groove is arranged on the valve body 41 to match the guide plate 446. The guide plate 446 is slidingly arranged in the guide groove, and the guide plate 446 guides the transmission rack 443 to move along the axial direction of the transmission screw 442, preventing the transmission rack 443 from being offset due to the radial force of the transmission gear 441, which causes the axial movement of the transmission screw 442 to be interfered.

[0045] Please refer to Figure 1 and Figure 5 In some embodiments, the heat dissipation assembly 2 includes a heat dissipation frame 21 connected to the reaction container 1, a plurality of liquid cooling pipes 22 arranged inside the heat dissipation frame 21, a liquid inlet pipe 23 having a liquid inlet port 231, and a liquid outlet pipe 24 having a liquid outlet port 241.

In this embodiment, the refrigeration circulator 31 includes a refrigeration box 311 and a circulating machine 312 mounted on the refrigeration box 311. The liquid delivery pipeline 32 is connected to the liquid inlet port 231 of the liquid inlet pipe 23 and the liquid outlet port of the circulating machine 312, respectively. The liquid return pipeline 33 is connected to the liquid return port of the refrigeration box 311 and the liquid outlet port 241 of the liquid outlet pipe 24, respectively. The cooling liquid in the refrigeration box 311 is pumped out by the circulating machine 312, and the pumped-out cooling liquid is transported to each liquid cooling pipe 22 of the heat dissipation assembly 2 through the liquid delivery pipeline 32 and the liquid inlet pipe 23. The cooling liquid flowing through each liquid cooling pipe 22 of the heat dissipation assembly 2 increases in temperature after absorbing heat. The cooling liquid with increased temperature is then concentrated and returned to the refrigeration box 311 through the liquid outlet pipe 24 and the liquid return pipeline 33. The cooling liquid with increased temperature is cooled by the refrigeration box 311 to a temperature range within a preset temperature range. The cooling liquid in the refrigeration box 311 is then pumped out to each liquid cooling pipe 22 of the heat dissipation assembly 2 by the circulating machine 312. The self-circulation of the cooling liquid is thus performed, and the chemical reaction heat generated in the reaction container 1 can be continuously removed by the cooling liquid in each liquid cooling pipe 22, thereby achieving the purpose of effectively controlling the temperature in the reaction container 1.

[0046] Please refer to Figure 1 and Figure 5 In some embodiments, the heat dissipation assembly 2 further includes a plurality of heat dissipation plates 25 arranged on the liquid cooling pipes 22. The heat dissipation plates 25 increase the heat dissipation area, so that the heat dissipation effect of the heat dissipation assembly 2 is better, and it is more conducive to rapidly and efficiently reducing the temperature in the reaction container 1. The heat dissipation assembly 2 further includes a heat dissipation fan 26 mounted on the heat dissipation frame 21. The heat dissipation fan 26 performs air cooling on the heat dissipation plates 25 and / or the reaction container 1, which is conducive to improving the heat dissipation effect.

The number of the heat dissipation assemblies 2 is at least two, the other end of each cooling liquid branch pipe 322 is in communication with the liquid inlet 231 of the corresponding heat dissipation assembly 2, and the other end of each liquid return branch pipe 332 is in communication with the liquid outlet 241 of the corresponding heat dissipation assembly 2. Through the above structure, the self-circulation supply of the cooling liquid to the multiple heat dissipation assemblies 2 can be realized through one circulation assembly 3, and the heat dissipation of the reaction container 1 is realized through the multiple heat dissipation assemblies 2, so that the heat dissipation efficiency and effect are improved, and the uniform consistency of heat dissipation of each part of the reaction container 1 is ensured. Increasing the number of the cooling liquid branch pipes 322 and the liquid return branch pipes 332 can further realize the heat dissipation of the multiple reaction containers 1. In addition, the flow regulating valve 4 is independently arranged on each cooling liquid branch pipe 322, so that the cooling liquid in each heat dissipation assembly 2 can be controlled respectively, which is beneficial to adaptively adjusting the flow of the cooling liquid supplied by the cooling liquid pipeline 32 to the heat dissipation assembly 2 according to the actual situation of the heat generated by the chemical reaction of the flow battery in the reaction container 1, so that the flow of the cooling liquid supplied by the circulation assembly 3 matches the heat generated by the chemical reaction of the flow battery.

[0048] In addition, the cooling and heat dissipation system further comprises a temperature sensor for detecting the temperature in the reaction container 1 and a controller for controlling the operation of the flow regulating valve 4 according to the temperature signal detected by the temperature sensor.
