Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of energy storage battery compartments, and in particular to an anti-condensation system for a liquid-cooled energy storage battery compartment. Background Art

[0002] In recent years, the construction of new energy, mainly photovoltaic and wind power, has developed rapidly. However, due to the characteristics of photovoltaic and wind power, the power generation is unstable, affecting the safety of the power grid and even causing the phenomenon of wind and solar power abandonment. The key to solving the above problems is to configure a certain proportion of energy storage systems for new energy. As a result, the construction of large-scale energy storage power stations has entered a fast track.

[0003] The core component of an energy storage power station is the battery, and the reliable and stable operation of the battery system is the core of the stable operation of the energy storage power station. At present, large-scale energy storage batteries are mainly installed through energy storage prefabricated cabins, and the main factors affecting the operating status of the battery system are the ambient temperature and humidity in the battery prefabricated cabin. Before 2021, the thermal management of energy storage batteries mainly used air conditioners as cooling and heating devices. Due to the working principle of air conditioners, when the air conditioners are cooling, the thermal management system can control the temperature and the humidity in the prefabricated cabin by collecting and discharging condensed water to avoid condensation. However, the air-cooled thermal management solution has disadvantages such as low heat exchange efficiency and large air duct space.

[0004] The emergence of battery system liquid cooling technology solves the problem of low heat dissipation efficiency of battery air cooling system. Liquid cooling pipes replace air ducts, freeing up more space, allowing more batteries to be arranged in the battery compartment, with higher energy density. However, the liquid cooling system regulates the temperature of the battery through a closed liquid circulation system and has no ability to regulate the air humidity in the environment. Therefore, the humidity in the battery compartment cannot be controlled, and condensation is easily formed, causing corrosion to electrical equipment such as the battery PACK, and even leakage, leading to serious faults such as short circuits. Summary of the invention

[0024] According to one aspect of the present invention, the condensed water collector further comprises: a water collecting pan, the water collecting pan being arranged below the dehumidifying liquid cooling plate, and the projection of the water collecting pan being larger than and covering the dehumidifying liquid cooling plate;

[0025] The water collecting tray is provided with a drainage hole, and the bottom of the drainage hole is connected to a drainage pipe.

[0026] According to one aspect of the present invention, the condensate collector further comprises: an installation column, wherein the installation column is installed at the free ends of the dehumidification liquid cooling plate and the water collecting tray, and the dehumidification liquid cooling plate and the water collecting tray are kept horizontal by positioning the installation column.

[0027] According to one aspect of the present invention, the water inlet of the liquid cooling pipeline structure and the water inlet of the condensate collector are respectively provided with controllable valves.

[0028] According to one solution of the present invention, a liquid-cooled energy storage battery compartment anti-condensation system comprises: an energy storage battery compartment, in which a plurality of energy storage batteries are arranged; a liquid cooling pipeline structure, arranged at the periphery of the energy storage battery; and a plurality of condensation water collectors, respectively connected to the liquid cooling pipeline structure, wherein the cold plate therein is cooled by a liquid cooling machine to form a cold surface, and the condensation water is collected on the surface of the cold plate and then discharged out of the energy storage battery compartment through a drain pipe. In this way, the cooling liquid can be transported to the liquid cooling pipeline structure by the liquid cooling machine, and the cooling liquid cools and absorbs the heat generated by the energy storage battery in the energy storage battery compartment through the liquid cooling pipeline structure. At the same time, the cooling liquid flows into each condensation water collector to cool the cold plate therein to form a cold surface. After the cold surface is formed, the air in the energy storage battery compartment is pre-cooled to form condensation, which is collected by the condensation water collector and discharged from the energy storage battery compartment, so that the energy storage battery compartment can be dehumidified in time without forming condensation, ensuring that the energy storage battery compartment has the ability to regulate humidity, ensuring that the internal battery PACK and other electrical equipment will not be corroded and leaked, and will not have serious faults such as short circuit.

[0029] According to one solution of the present invention, the liquid cooling pipeline structure includes: a liquid cooling main pipeline and a plurality of liquid cooling branches; wherein the liquid cooling main pipeline and the liquid cooling branches both include a water inlet pipeline and a water outlet pipeline; the liquid cooling main pipeline is arranged on both sides of the top of each energy storage battery; each liquid cooling branch is arranged along the vertical direction, and each liquid cooling branch is arranged at intervals, one end of which is arranged on the side wall of each energy storage battery, and the other end is connected to the liquid cooling main pipeline, that is, the water inlet pipeline of the liquid cooling main pipeline is connected to the water inlet pipeline of the liquid cooling branch, and the water outlet pipeline of the liquid cooling main pipeline is connected to the water outlet pipeline of the liquid cooling branch. With such an arrangement, the energy storage batteries in the energy storage battery compartment can be surrounded by the liquid cooling main pipeline and the plurality of liquid cooling branches, so that the cooling coverage area is larger, and the cooling and heat dissipation effect in the energy storage battery compartment is better and faster.

[0030] According to one solution of the present invention, each condensate collector is connected to the main liquid cooling line and is located around the energy storage battery. In this way, the internal space of the energy storage battery compartment can be effectively dehumidified through each condensate collector, ensuring that the humidity around the energy storage battery is controllable and that each energy storage battery is not affected by moisture.

[0031] According to one solution of the present invention, the condensate collector includes: a dehumidified liquid cold plate; each dehumidified liquid cold plate is connected to a liquid cooling main line and is located around the energy storage battery; a liquid flow pipeline is provided inside the dehumidified liquid cold plate, and a liquid cold plate water inlet and a liquid cold plate water outlet connected to the liquid flow pipeline are provided on its surface; the liquid cold plate water inlet is connected to the liquid cooler water outlet through the liquid cooling main line (water inlet pipeline), and the liquid cold plate water outlet is connected to the liquid cooler water inlet through the liquid cooling main line (water outlet pipeline). With such a configuration, the dehumidified liquid cold plate can be cooled by conveying cooling water to the dehumidified liquid cold plate through the liquid cooler, so that after the dehumidified liquid cold plate forms a cold surface, the humid air in the energy storage battery compartment is condensed into condensation and then discharged from the energy storage battery compartment through the drain pipe provided on the condensate collector, so that the environmental humidity in the energy storage battery compartment meets the standard and malfunctions are avoided.

[0032] According to one solution of the present invention, each condensate collector is arranged on each liquid cooling branch at intervals along the vertical direction, and its upper surface is supported on the bottom of the energy storage battery housing. That is, each condensate collector is installed on each liquid cooling branch at intervals along the vertical direction, and supports each energy storage battery. Such an arrangement enables each condensate collector to efficiently dehumidify the internal environment of the energy storage battery compartment, so that there are no moist pores between the energy storage batteries, and no moist corners are left, thereby ensuring the overall environmental dehumidification effect in the energy storage battery compartment and ensuring that each energy storage battery is not affected by moisture.

[0033] According to one solution of the present invention, the condensate collector includes: a dehumidified liquid cooling plate; each dehumidified liquid cooling plate is arranged at intervals on each liquid cooling branch along the vertical direction, and its upper surface is supported on the bottom of the energy storage battery shell; a liquid flow pipeline is arranged inside the dehumidified liquid cooling plate, and a liquid cooling plate water inlet and a liquid cooling plate water outlet connected to the liquid flow pipeline are arranged on its surface; the liquid cooling plate water inlet is connected to the liquid cooling machine water outlet through the liquid cooling branch, and the liquid cooling plate water outlet is connected to the liquid cooling machine water inlet through the liquid cooling branch. The dehumidified liquid cooling plate is installed on each liquid cooling branch and is located at the bottom of each energy storage battery shell. Such an arrangement has a better dehumidification effect, and the area around each energy storage battery can be effectively dehumidified without leaving a dehumidification dead corner, making the overall environment in the energy storage battery compartment safer and more reliable.

[0034] According to one solution of the present invention, the upper surface of the dehumidified liquid cooling plate is coated with a heat-insulating material, and the lower surface is a condensed water collection surface. With this arrangement, condensation can be formed on the lower surface of the dehumidified liquid cooling plate, and the formed condensation drips downward through the condensed water collection surface. With this arrangement, the condensation can be better collected and will not affect the energy storage battery above.

[0035] According to one solution of the present invention, the condensed water collector further includes: a water collecting tray, which is arranged below the dehumidified liquid cooling plate, and the projection of the water collecting tray is larger than and covers the dehumidified liquid cooling plate; the water collecting tray is provided with a drainage hole, and the bottom of the drainage hole is connected to a drainage pipe. With such a configuration, after condensation on the lower surface of the dehumidified liquid cooling plate, the condensation can drip into the water collecting tray and gather, and then enter the drainage pipe through the drainage hole on the water collecting tray, and then be discharged from the energy storage battery compartment, so that the humidity in the energy storage battery compartment meets the standard, effectively achieves the dehumidification effect, and ensures that the energy storage battery and other devices in the energy storage battery compartment are always in a safe working state.

[0036] According to one solution of the present invention, the condensed water collector further comprises: an installation column, the installation column is installed at the free end of the dehumidified liquid cooling plate and the water collecting tray, and the dehumidified liquid cooling plate and the water collecting tray are kept horizontal by positioning the installation column. In this way, the installation and fixation of the installation column can keep the dehumidified liquid cooling plate and the water collecting tray in a horizontal state at all times, so that the condensed water on the dehumidified liquid cooling plate and the water collecting tray will not be tilted and spilled to the outside or difficult to enter the drain pipe for discharge.

[0037] According to one solution of the present invention, a controllable valve is provided at the water inlet of the liquid cooling pipeline structure and the water inlet of the condensed water collector. With such a configuration, when a dehumidification operation is required, the controllable valve of the liquid cooling pipeline structure is closed, and the controllable valve of the water inlet of the condensed water collector is opened. When the battery needs to be cooled, the valve of the liquid cooling pipeline structure is opened.

[0038] According to the solution of the present invention, the present invention utilizes the refrigeration function of the liquid cooling unit compressor to add a liquid cooling plate for dehumidification in the existing battery liquid cooling pipeline system, utilizes the condensation effect of the liquid cooling plate to collect condensed water in the air, and then collects and stores the condensed water and discharges it downwardly out of the battery compartment through a pipe.

[0039] According to the solution of the present invention, a number of condensation water collectors are added to the liquid cooling pipeline. When the humidity in the battery compartment is too high, the liquid cooler is started for cooling. The low temperature effect generated by the liquid cooler is utilized to condense the water vapor in the air through the condensation water collector, actively forming condensation and collecting the condensation flow, which is then discharged out of the cabin along the condensation collection pipeline, thereby achieving the purpose of actively reducing the air humidity in the battery compartment and preventing condensation from occurring.

[0040] According to the solution of the present invention, the present invention designs a liquid-cooled energy storage battery compartment anti-condensation system, utilizes the characteristics of the liquid cooler compressor with refrigeration function, and adds an additional liquid cooling plate for dehumidification in the battery liquid cooling system to collect water vapor in the air in the battery compartment, which can effectively reduce the absolute humidity of the air in the battery compartment and avoid condensation. Compared with the solution of using air conditioning dehumidification and anti-condensation, the present invention does not need to add additional active equipment, and has low cost and high reliability; compared with the anti-condensation solution of using a heater to increase the temperature and reduce the relative humidity of the air, this solution can reduce the absolute humidity of the air and discharge the water vapor out of the cabin, with good dehumidification effect and little impact on the temperature in the cabin; compared with semiconductor condensation dehumidification, this solution does not need to add additional active equipment, and relies on the powerful performance of the liquid cooler to have a strong dehumidification capacity.

[0048] A plurality of condensed water collectors 4 are respectively connected to the liquid cooling pipe structure 3, and the cold plates therein are cooled by the liquid cooling machine to form a cold surface, and the condensed water is collected on the surface of the cold plate and then discharged out of the energy storage battery compartment through the drain pipe. With such an arrangement, the cooling liquid can be transported to the liquid cooling pipe structure 3 by the liquid cooling machine, and the cooling liquid cools and absorbs the heat generated by the energy storage battery 2 in the energy storage battery compartment 1 through the liquid cooling pipe structure 3. At the same time, the cooling liquid flows into each condensed water collector 4 to cool the cold plates therein to form a cold surface. After the cold surface is formed, the air in the energy storage battery compartment 1 is pre-cooled to form condensation, which is collected by the condensed water collector 4 and discharged from the energy storage battery compartment 1, so that the energy storage battery compartment 1 can be dehumidified in time without forming condensation, ensuring that the energy storage battery compartment 1 has the ability to regulate humidity, ensuring that the internal battery PACK and other electrical equipment will not be corroded and leaked, and that serious faults such as short circuits will not occur.

[0049] Furthermore, if Figure 1 As shown, in this embodiment, the liquid cooling pipeline structure 3 includes: a liquid cooling main pipeline 5 and a plurality of liquid cooling branches 6;

[0050] The liquid cooling main circuit 5 and the liquid cooling branch circuit 6 both include a water inlet pipe and a water outlet pipe;

[0051] The liquid cooling main line 5 is arranged on both sides of the top of each energy storage battery;

[0052] Each liquid cooling branch 6 is arranged along the vertical direction, and each liquid cooling branch 6 is arranged at intervals, one end of which is arranged on the side wall of each energy storage battery, and the other end is connected to the liquid cooling main line 5, that is, the water inlet pipeline of the liquid cooling main line 5 is connected to the water inlet pipeline of the liquid cooling branch 6, and the water outlet pipeline of the liquid cooling main line 5 is connected to the water outlet pipeline of the liquid cooling branch 6. In this way, the energy storage battery 2 in the energy storage battery compartment 1 can be surrounded by the liquid cooling main line 5 and a plurality of liquid cooling branches 6, so that the cooling coverage area is larger, and the cooling and heat dissipation effect in the energy storage battery compartment 1 is better and faster.

[0053] Further, according to one embodiment of the present invention, Figure 1 As shown, each condensate collector 4 is connected to the liquid cooling main line 5 and is located around the energy storage battery. In this way, the internal space of the energy storage battery compartment 1 can be effectively dehumidified through each condensate collector 4, ensuring that the humidity around the energy storage battery is controllable and that each energy storage battery is not affected by moisture.

[0054] Further, in this embodiment, the condensate collector 4 includes: a dehumidifying liquid cooling plate 7;

[0055] Each dehumidification liquid cooling plate 7 is connected to the liquid cooling main line 5 and is located around the energy storage battery;

[0056] A liquid flow pipeline (not shown in the figure) is arranged inside the dehumidified liquid cooling plate 7, and a liquid cooling plate water inlet 8 and a liquid cooling plate water outlet 9 connected to the liquid flow pipeline are arranged on its surface;

[0057] The water inlet 8 of the liquid cooling plate is connected to the water outlet of the liquid cooling machine through the liquid cooling main line (water inlet line), and the water outlet of the liquid cooling plate is connected to the water inlet of the liquid cooling machine through the liquid cooling main line (water outlet line). With such an arrangement, cooling water can be transported to the dehumidifying liquid cooling plate 7 by the liquid cooling machine to cool the dehumidifying liquid cooling plate 7, so that the dehumidifying liquid cooling plate 7 forms a cold surface, condenses the humid air in the energy storage battery compartment 1 into condensation, and then discharges it from the energy storage battery compartment 1 through the drain pipe provided on the condensation water collector 4, so that the environmental humidity in the energy storage battery compartment 1 meets the standard and avoids malfunctions.

[0058] Further, according to another embodiment of the present invention, each condensate collector 4 is arranged on each liquid cooling branch 6 at intervals along the vertical direction, and its upper surface is supported on the bottom of the energy storage battery housing. That is, each condensate collector is installed on each liquid cooling branch at intervals along the vertical direction, and supports each energy storage battery. Such an arrangement can make it possible to efficiently dehumidify the internal environment of the energy storage battery compartment 1 through each condensate collector, so that there are no moist pores between the energy storage batteries, and no moist corners are left, thereby ensuring the overall environmental dehumidification effect in the energy storage battery compartment 1 and ensuring that each energy storage battery is not affected by moisture.

[0059] Further, in this embodiment, the condensate collector includes: a dehumidifying liquid cooling plate;

[0060] Each dehumidification liquid cooling plate is arranged on each liquid cooling branch 6 at intervals along the vertical direction, and its upper surface is supported on the bottom of the energy storage battery housing;

[0061] A liquid flow pipeline is arranged inside the dehumidification liquid cooling plate, and a liquid cooling plate water inlet and a liquid cooling plate water outlet connected to the liquid flow pipeline are arranged on the surface of the dehumidification liquid cooling plate;

[0062] The water inlet of the liquid cooling plate is connected to the water outlet of the liquid cooling machine through the liquid cooling branch, and the water outlet of the liquid cooling plate is connected to the water inlet of the liquid cooling machine through the liquid cooling branch. In this embodiment, the structure of the dehumidification liquid cooling plate is the same as the structure of the dehumidification liquid cooling plate 7 in the above embodiment, and the difference lies in the installation position. The dehumidification liquid cooling plate in this embodiment is installed on each liquid cooling branch 6 and is located at the bottom of each energy storage battery shell. Such a setting has a better dehumidification effect, and the area around each energy storage battery can be effectively dehumidified without leaving a dehumidification dead corner, making the overall environment in the energy storage battery compartment 1 safer and more reliable.

[0063] Further, according to an embodiment of the present invention, the upper surfaces of the dehumidification liquid cooling plates in the above two installation states are coated with heat insulation materials, and the lower surfaces are condensation water collection surfaces.

When the humidity in the battery compartment is too high, the liquid cooler is started for cooling. The low temperature effect generated by the liquid cooler is utilized to condense the water vapor in the air through the condensation water collector, actively forming condensation and collecting the condensation flow, which is then discharged out of the cabin along the condensation collection pipeline, thereby achieving the purpose of actively reducing the air humidity in the battery compartment and preventing condensation from occurring.
