Description
Technical Field
The utility model relates to the field of thermal management of battery energy storage systems, in particular to a liquid cooling pipeline.
Background
Wind power and photoelectricity often need to be acted by thermal power or a corresponding energy storage system when being integrated into a power grid due to the fact that the wind power and photoelectricity have fluctuation in time. The energy storage generally adopts an energy storage scheme like a battery.
Batteries need to be organized in clusters in order to be able to accommodate the vast amount of electricity that new energy sources emit. In the charge and discharge process, the battery releases heat, and the charge and discharge speed of the battery is slowed down due to the existence of temperature difference.
For the battery cooling of liquid cooling scheme, at the in-process that the coolant liquid circulated the cooling, because the pipeline is comparatively complicated, the change of speed size arouses pressure variation, and the temperature rise also can cause the precipitation of gas in the coolant liquid, reduces radiating efficiency.
The application aims to provide a liquid cooling pipeline, which has more uniform flow distribution.
Disclosure of Invention
The utility model overcomes the defects of difficult flow rate of each heat exchanger in the existing liquid cooling system, large temperature difference and difficult management, and provides the liquid cooling pipeline which can improve the flow rate passing through the heat exchangers and lead the flow rate distribution to be more uniform.
In order to solve the technical problems, the utility model adopts the following technical scheme:
The liquid cooling pipeline comprises a liquid inlet pipe and a liquid outlet pipe which are used for being connected with heat exchangers, wherein each heat exchanger is vertically arranged to form heat exchange stacks, a plurality of heat exchange stacks are arranged along the linear direction, and the travel of a circulation loop formed by the heat exchangers with the same height positions in each heat exchange stack, the liquid inlet pipe and the liquid outlet pipe is the same.
For a plurality of heat exchangers, even a heat exchanger stack formed by the heat exchangers, the connection to the inlet and outlet pipes forms a separate cooling circuit. The total path of the cooling circuit and the shorter cooling circuit naturally have larger flow, and the obtained cold quantity is also more, so that the temperature of the battery pack corresponding to the heat exchanger is lower. The difference in temperature between the battery pack and other battery packs also causes the difference in charge and discharge speeds thereof, resulting in reduced consistency. Therefore, the application makes the flow rate and speed of the heat exchangers at the same height and layer the same by constructing the circulation loops with the same stroke, improves the uniformity of flow distribution and reduces the difficulty of flow management.
Preferably, the liquid inlet pipe comprises a liquid inlet main pipe, a liquid inlet branch pipe and a liquid inlet branch pipe, the liquid outlet pipe comprises a liquid outlet main pipe, a liquid outlet branch pipe and a liquid outlet branch pipe, the liquid inlet main pipe and the liquid outlet main pipe are arranged in parallel, and the directions of the cooling liquid flow directions are the same, the liquid inlet branch pipe and the liquid outlet branch pipe are vertically arranged, the liquid inlet branch pipe is connected to the liquid inlet branch pipe along the length direction of the liquid inlet branch pipe, the liquid outlet branch pipe is connected to the liquid outlet branch pipe along the length direction of the liquid outlet branch pipe, and the liquid inlet branch pipe and the liquid outlet branch pipe are respectively connected to the left end and the right end of a heat exchanger. The same travel of the circulation loop is based on the construction of the same-travel loop, and is specifically realized by the mode that the liquid inlet main pipe and the liquid outlet main pipe are arranged in parallel and the flowing direction of the cooling liquid is the same. For the heat exchanger close to the upstream, the path from the inlet of the liquid inlet main pipe to the heat exchanger is shorter, and the path from the heat exchanger to the outlet of the liquid outlet main pipe is longer; correspondingly, for the heat exchanger close to the downstream, the path of the inlet of the liquid inlet main pipe reaching the heat exchanger is longer, and the path of the inlet of the liquid outlet main pipe reaching the liquid outlet main pipe is shorter. The flow obtained by each heat exchange stack is similar and uniform through the step-by-step transmission of the main pipe, the branch pipe and the branch pipe.
Preferably, the liquid inlet branch pipes are arranged on the liquid inlet branch pipes at equal intervals; the liquid outlet branch pipes are arranged on the liquid outlet branch pipes at equal intervals. Because the corresponding battery packs of the heat exchangers are modularized, the sizes and the heights of the battery packs are the same, and therefore, in order to be in butt joint with the corresponding heat exchangers, the liquid inlet branch pipes and the liquid outlet branch pipes are uniformly distributed on the liquid inlet branch pipes and the liquid outlet branch pipes.
Preferably, a switch valve is arranged between the liquid inlet branch pipe and the liquid inlet main pipe and between the liquid outlet branch pipe and the liquid outlet main pipe. When a certain group of battery clusters fail or do not need to be cooled, the branch pipe communicated with the battery clusters is cut off from the main pipe through the switch valve, so that the battery clusters can be prevented from being cooled unnecessarily, and resource waste is avoided.
Preferably, the on-off valve is a solenoid valve. The electromagnetic valve supports automatic control, and reduces manpower.
Preferably, the main liquid inlet pipe and the main liquid outlet pipe are positioned above the branch liquid inlet pipe and the branch liquid outlet pipe, and the inner diameters of the branch pipe orifices of the branch liquid inlet pipe and the branch liquid inlet pipe connected with the branch liquid inlet pipe are gradually reduced from high to low along the length direction of the branch liquid inlet pipe. The liquid inlet branch pipe at the lower part has higher pressure, and the reduction of the corresponding branch pipe orifice is beneficial to reducing the flow entering the liquid inlet branch pipe, so that the flow is more uniform for the heat exchangers with different heights in the same heat exchange stack.
Preferably, the liquid outlet main pipe is provided with an exhaust valve. The exhaust valve can exhaust the gas therein, so that bubbles are prevented from accumulating in circulation, and the heat dissipation effect of the energy storage device is ensured.
Compared with the prior art, the utility model has the beneficial effects that: by constructing equal-stroke circulation loops for the heat exchangers with the same height of the heat exchanger, the flow and the flow velocity are similar, and the control complexity is reduced.

Examples:
The liquid cooling pipeline comprises a liquid inlet pipe 1 and a liquid outlet pipe 2 which are connected with heat exchangers, wherein each heat exchanger is vertically arranged to form heat exchange stacks, a plurality of heat exchange stacks are arranged along the linear direction, and the travel of a circulation loop formed by the heat exchangers with the same height position in each heat exchange stack, the liquid inlet pipe 1 and the liquid outlet pipe 2 is the same. Specifically, the liquid inlet pipe 1 includes the liquid inlet main pipe 11, the liquid inlet branch pipe 12 and the liquid inlet branch pipe 13, the drain pipe 2 includes the liquid outlet main pipe 21, the liquid outlet branch pipe 22 and the liquid outlet branch pipe 23, the liquid inlet main pipe 11 and the liquid outlet main pipe 21 parallel arrangement and the coolant flow direction are the same, the liquid inlet branch pipe 12 and the liquid outlet branch pipe 22 vertical arrangement, the liquid inlet branch pipe 13 is connected on the liquid inlet branch pipe 12 along the length direction of the liquid inlet branch pipe 12, the liquid outlet branch pipe 23 is connected on the liquid outlet branch pipe 22 along the length direction of the liquid outlet branch pipe 22, to a heat exchanger, the liquid inlet branch pipe 13 and the liquid outlet branch pipe 23 are connected respectively at the left and right ends of the heat exchanger.
The liquid inlet branch pipes 13 are arranged on the liquid inlet branch pipes 12 at equal intervals; the liquid outlet branch pipes 23 are arranged on the liquid outlet branch pipe 22 at equal intervals. Since the corresponding battery packs of the heat exchangers are modularized and have the same size and height, the liquid inlet branch pipes 13 and the liquid outlet branch pipes 23 are uniformly arranged on the liquid inlet branch pipes 12 and the liquid outlet branch pipes 22 for being in butt joint with the corresponding heat exchangers.
The same travel of the circulation loop is based on the construction of the same travel loop, and is specifically realized by the way that the main liquid inlet pipe 11 and the main liquid outlet pipe 21 are arranged in parallel and the flowing directions of the cooling liquid are the same. For the heat exchanger close to the upstream, the path from the inlet of the liquid inlet main pipe 11 to the heat exchanger is shorter, and the path from the heat exchanger to the outlet of the liquid outlet main pipe 21 is longer; correspondingly, for a heat exchanger close to the downstream, the inlet of the main inlet pipe 11 will reach the heat exchanger longer, and the outlet pipe 21 will reach the outlet pipe shorter. The flow obtained by each heat exchange stack is similar and uniform through the step-by-step transmission of the main pipe, the branch pipe and the branch pipe.
An on-off valve 3 is arranged between the liquid inlet branch pipe 12 and the liquid inlet main pipe 11 and between the liquid outlet branch pipe 22 and the liquid outlet main pipe 21. When a certain group of battery clusters fail or do not need to be cooled, the branch pipe communicated with the battery clusters is cut off from the main pipe through the switch valve 3, so that the unnecessary cooling of the battery clusters can be avoided, and the resource waste is avoided. Wherein the switch valve 3 is an electromagnetic valve. The electromagnetic valve supports automatic control, and reduces manpower.
The main liquid inlet pipe 11 and the main liquid outlet pipe 21 are located above the branch liquid inlet pipe 12 and the branch liquid outlet pipe 22, and as shown in fig. 3, the inner diameter of the branch pipe orifice 14 of the branch liquid inlet pipe 12 connected with the branch liquid inlet pipe 13 gradually decreases from high to low along the length direction of the branch liquid inlet pipe 12. The lower inlet manifold 13 has a greater pressure, and reducing its corresponding manifold orifice 14 advantageously reduces the flow into it, making it more uniform for different heights of heat exchangers in the same heat exchanger stack.
The liquid outlet main pipe 21 is provided with an exhaust valve 4. The exhaust valve 4 can exhaust the gas therein to avoid the accumulation of bubbles in circulation, thereby ensuring the heat dissipation effect of the energy storage device.
For a plurality of heat exchangers, even a heat exchanger stack formed by the heat exchangers, the connection to the inlet pipe 1 and the outlet pipe 2 forms separate cooling circuits. The total path of the cooling circuit and the shorter cooling circuit naturally have larger flow, and the obtained cold quantity is also more, so that the temperature of the battery pack corresponding to the heat exchanger is lower. The difference in temperature between the battery pack and other battery packs also causes the difference in charge and discharge speeds thereof, resulting in reduced consistency. Therefore, the application makes the flow rate and speed of the heat exchangers at the same height and layer the same by constructing the circulation loops with the same stroke, improves the uniformity of flow distribution and reduces the difficulty of flow management.
The above-described embodiments are merely preferred embodiments of the present utility model, and the present utility model is not limited in any way, and other variations and modifications may be made without departing from the technical aspects set forth in the claims.
