Description

Technical Field

[0002] The constant temperature control device of the energy storage system container is a device used to control the temperature inside the energy storage system container; the energy storage system container is a device used to store and protect energy storage equipment, and the constant temperature control device can keep the temperature inside the energy storage system container within a set constant temperature range;

[0003] The constant temperature control device usually includes components such as a temperature sensor, a controller, a heater and a refrigerator. The temperature sensor is used to monitor the temperature in the container and transmit the real-time temperature information to the controller. The controller controls the heater and refrigerator to adjust the temperature in the container. When the temperature in the container exceeds the set upper limit temperature, the controller will start the refrigerator to lower the temperature. When the temperature is lower than the set lower limit temperature, the controller will start the heater to increase the temperature. Through continuous monitoring and adjustment, the constant temperature control device can ensure that the temperature in the energy storage system container remains stable within the required constant temperature range.

[0041] The present invention provides the following embodiments

[0042] Example 1

[0043] The embodiment of the present invention provides a constant temperature control device for an energy storage system container, such as Figure 1-7 As shown, it includes a container 1, a partition 100 is provided in the container 1, two symmetrically arranged partitions 1000 are fixedly connected to the partition 100, a monitoring equipment cavity 1001 is formed between the two partitions 1000 and the inner wall of the container 1, battery installation cavities 1002 are provided on both sides of the monitoring equipment cavity 1001, the monitoring equipment cavity 1001 is used to store the monitoring component, the battery installation cavity 1002 is used to store the battery pack 1003, a primary temperature control component 2 and a secondary temperature control component 3 are provided in the container 1, the primary temperature control component 2 and the secondary temperature control component 3 are both electrically connected to the monitoring component, the primary temperature control component 2 uses groundwater resources to perform constant temperature control on the energy storage system, and the secondary temperature control component 3 uses a refrigeration component and a heating component to cooperate with each other to perform constant temperature control on the energy storage system.

[0044] The working principle and beneficial effects of the above technical solution are as follows: when the temperature detection value of the battery installation cavity 1002 by the monitoring component is between the first-level preset detection value and the second-level preset detection value, the first-level temperature control component 2 starts to adjust the temperature in the battery installation cavity 1002 through groundwater; when the temperature detection value of the battery installation cavity 1002 is higher than the first-level preset detection value, the second-level temperature control component 3 starts to adjust the temperature in the battery installation cavity 1002; when the temperature detection value of the battery installation cavity 1002 is higher than the third-level preset detection value, the first-level temperature control component 2 and the second-level temperature control component 3 are started at the same time to adjust the temperature in the battery installation cavity 1002, wherein the second-level preset detection value is greater than the first-level preset detection value, and the third-level preset detection value is greater than the second-level preset detection value;

[0045] Compared with the traditional constant temperature control device, the present invention introduces a primary temperature control component 2, utilizes natural resources for temperature regulation, and activates different temperature regulation schemes based on different temperature detection values, thereby maximally saving the power consumption of the energy storage system by the constant temperature control device.

[0046] Example 2

[0047] On the basis of Example 1, the first-level temperature control component 2 includes an underground water tank 200, a transfer water chamber 201 is provided on the top of the container 1, the transfer water chamber 201 is connected to the ground water distribution system, a stirring paddle and a water temperature sensor are provided in the transfer water chamber 201, the water temperature sensor is electrically connected to the monitoring component, the underground water tank 200 is connected to the transfer water chamber 201 through an inlet pipe 202, a pump body 203 is provided on the inlet pipe 202, a spiral water pipeline 204 is embedded in the two partitions 1000 and the side wall of the container 1, the inlet end of the spiral water pipeline 204 is connected to the transfer water chamber 201, and the outlet end of the spiral water pipeline 204 is connected to a return water pipe 205, and the end of the return water pipe 205 away from the spiral water pipeline 204 is located in the underground water tank 200.

[0048] The working principle and beneficial effects of the above technical solution are as follows: when the primary temperature control component 2 is working, the pump body 203 starts to pump the water in the underground water tank 200 into the transfer water chamber 201 through the water inlet pipe 202, and the groundwater pumped into the transfer water chamber 201 flows into the spiral water pipe 204 to participate in heat exchange, so that the temperature of the battery installation chamber 1002 is controlled within a preset temperature range, and the groundwater after participating in the heat exchange flows back to the underground water tank 200 through the return pipe 205. The water temperature of the groundwater is usually warm in winter and cool in summer, which can provide heating for the container in winter and cooling for the container in summer, thereby meeting the constant temperature requirement of the battery installation chamber 1002;

[0049] When the temperature of the groundwater cannot meet the temperature control requirements, the ground water distribution system is started, and a certain amount of water at a certain temperature is added to the battery installation cavity 1002, so that the groundwater after the addition meets the temperature control requirements. Specifically, after the groundwater flows into the transfer water cavity 201, the stirring paddle starts working. At the same time, based on the temperature detection result of the monitoring component, the ground water distribution system adds a certain amount of water at a certain temperature into the transfer water cavity 201, so that the detection value of the water temperature sensor is within the preset range. After that, the added water is passed into the spiral water pipeline 204 to participate in heat exchange. The water after heat exchange flows back to the underground water storage tank 200 through the return pipe 205.

A plurality of heat exchange fans 302 are rotatably connected in the heat exchange fan installation cavity 301.

[0052] The working principle and beneficial effects of the above technical solution are as follows: when the secondary temperature control component 3 is working, the working intensity of the air-conditioning outdoor unit 300 is controlled based on the temperature detection result of the monitoring component, thereby realizing heat exchange between the battery installation cavity 1002 and the outside air, and realizing temperature regulation of the battery installation cavity 1002.

[0059] The working principle and beneficial effects of the above technical solution are as follows: when installing the battery pack 1003, the left and right side walls of the container are opened, and then the electric shift screw 1010 rotates to drive the shift nut 1011 to move under the action of the thread, so that the bottom placement plate 1012 and the upper placement plate 1014 thereon are moved out of the container 1. When the battery pack catches fire, the burning battery pack can also be moved out of the container 1 in time by the electric shift screw 1010 to avoid the explosion of the container 1 due to gas expansion.

When the sliding plate 5002 moves upward, the pull rope 5004 pulls the gate 5025 downward, and the compression elastic member 5005 is gradually compressed. At the same time, when the smoke alarm detects smoke, the fire extinguishing component 501 is activated;

[0072] When the fire extinguishing component 501 is working, the electric nozzle adjusting screw 5010 rotates to drive the nozzle adjusting nut 5011 to move under the action of the thread. The movement of the nozzle adjusting nut 5011 drives the nozzle 5013 to move outward and extend into the battery installation cavity 1002. At the same time, the air pump 5028 is started to output the carbon dioxide in the carbon dioxide storage chamber 5016 to the nozzle 5013. At the same time, the electric auger 5021 rotates to input the powder in the fire extinguishing powder storage chamber 5020 into the powder supply chamber 5022. Then, the negative pressure fan 5024 rotates to input the powder input into the powder supply chamber 5022 into the connecting pipe 2 5017, and then enters the connecting pipe 1 5015 through the connecting pipe 2 5017. During the operation of the negative pressure fan 5024, the electric disc net 5023 rotates. Thereby, the effect of the negative pressure fan 5024 is enhanced. If a large amount of powder is input into the powder chamber 5022 , the excess powder will fall into the fire extinguishing powder storage chamber 5020 through the electric disc net 5023 .

[0081] Step 1: Calculate the actual leakage coefficient of the spiral water pipe 204 based on the flow rate sensor, timer, temperature sensor, pressure sensor 1 and pressure sensor 2:

[0082]

[0085] The working principle and beneficial effects of the above technical solution are as follows: although the use of the spiral water pipe 204 for liquid cooling and temperature control saves resources, there are certain safety hazards.
