Description

Technical Field

[0001] The utility model relates to a liquid flow frame, in particular to a liquid flow frame applied to a vanadium liquid flow battery. Background Art

[0002] The all-vanadium liquid flow battery uses vanadium ion solutions of different valence states as positive and negative electrolytes. The electrolyte is driven by an external pump to circulate between the storage tank and the battery stack. The electrolyte undergoes redox reactions in the battery stack to complete the charging and discharging process. The liquid flow frame is very common. Electrolyte is mostly introduced into the liquid flow frame to react chemically with the battery. Currently, the flow channels are mostly set in horizontal and vertical styles. There will be multiple large bends in the flow channel, which will cause the resistance of the electrolyte to increase when it circulates, increase the effective resistance of the battery self-discharge, and slow down the speed of self-discharge. In addition, when the battery is working, the electrolyte will undergo a chemical reaction in the liquid flow frame, and a large amount of heat will be generated during the chemical reaction.

[0003] After long-term use, the heat dissipation holes of the liquid flow frame of the existing vanadium liquid flow battery are easily blocked by dust, which makes it inconvenient to clean and maintain the heat dissipation holes, resulting in poor heat dissipation effect and affecting the conversion efficiency between battery charge and discharge. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a liquid flow frame for vanadium liquid flow batteries, which effectively solves the problem that the heat dissipation holes of the liquid flow frame of the existing vanadium liquid flow battery are easily blocked by dust after long-term use, making it inconvenient to clean and maintain the heat dissipation holes, resulting in poor heat dissipation effect and affecting the conversion efficiency between battery charging and discharging.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes an externally arranged liquid flow frame, a cylindrical grid installed in the middle of the liquid flow frame, a mainstream channel installed on the cylindrical grid, a liquid inlet pipe arranged at one end of the mainstream channel and a liquid outlet pipe arranged at the other end of the mainstream channel, and also includes a first heat sink, a first dustproof net, a heat dissipation fan, a second heat sink, a second dustproof net, an insert, a slot, a first bevel tooth, a fixing plate, a second bevel tooth, a groove, a spring, a guide wheel, a pull rope and a pull ring. The first heat sink is installed in the middle of one side of the liquid flow frame, and the first dustproof is installed in the middle of the first heat sink. A cooling fan is installed in the middle of the other side of the liquid flow frame, a second heat sink is plugged into the liquid flow frame outside the heat sink, a second dust-proof net is installed inside the second heat sink, plug blocks are provided in the middle of both ends of the second heat sink, both ends of the first heat sink are provided with first bevel teeth, fixed plates are embedded and installed in the liquid flow frame at both ends of the first heat sink, one end of the fixed plate is provided with second bevel teeth, a groove is opened in the liquid flow frame corresponding to the position of the fixed plate, a spring fixed in the groove is installed on one side of the fixed plate, a guide wheel is embedded in the liquid flow frame, a draw rope is wound around the guide wheel, and a draw ring is fixed at one end of the draw rope.

[0006] Preferably, a slot is provided in the liquid flow frame at a position corresponding to the plug-in block.

[0007] Preferably, the other end of the pull rope is connected to the middle part of the fixing plate.

[0008] Preferably, the liquid flow frame is provided with a through hole at a position corresponding to the pull rope.

[0009] Preferably, the right-angle end of the first bevel tooth is on the outside, and the diameter end of the second bevel tooth is on the inside.

[0010] Preferably, buckle grooves are provided at the middle parts of both sides of the first heat dissipation plate and the second heat dissipation plate.

[0011] When the heat dissipation device is used, the first heat dissipation plate is directly dissipated in the liquid flow frame, and the heat dissipation performance of the liquid flow frame is guaranteed, thereby ensuring the performance of the battery. When the first dustproof net needs to be cleaned, the pull ring is pulled, the pull ring pulls the pull rope, and the pull rope pulls the fixing plate to overcome the elastic force of the spring and moves outward. The fixing plate moves so that the second bevel teeth are separated from the first bevel teeth. At this time, the first heat dissipation plate can be taken out, and the first dustproof net on the first heat dissipation plate can be cleaned. When the cleaning is completed and the installation is completed, the first heat dissipation plate can be directly pushed into the liquid flow frame. When pushing in, the first bevel teeth push the second bevel teeth, and the second bevel teeth push the fixing plate until the first bevel teeth and the second bevel teeth are meshed together. The installation can be completed by pushing the limit by the set spring. When the second dustproof net needs to be cleaned, the second heat dissipation plate is pushed upward. After pushing out, the second dustproof net can be cleaned. When installing, the plug on the second heat dissipation plate is plugged into the slot, and the second heat dissipation plate is pushed into the liquid flow frame, which is easy to operate. The utility model has a novel structure and an ingenious design, and is convenient for disassembling and cleaning the heat dissipation and dustproof net. At the same time, the utility model is simple to install and is conducive to the use of the liquid flow frame. BRIEF DESCRIPTION OF THE DRAWINGS
