Description

Technical Field

[0001] The present application relates to the field of temperature control technology, and more specifically, to a temperature control system and method. Background Art

[0002] Since temperature affects the capacity, safety, life and other performance of the equipment, in order to ensure the long-term safe and stable operation of the equipment, it is generally necessary to configure a temperature control system to control the temperature.

[0003] For example, energy storage equipment includes battery modules and energy storage converters (Power Conversion System, PCS) and other devices. Figure 1 As shown in the schematic diagram of the basic structure of the energy storage device, in the related art, the temperature control machine 11 is generally used to control the temperature of the battery module 12 and the energy storage converter 13, two types of temperature-controlled devices. However, the battery module and the PCS have different temperature requirements. The temperature requirement of the battery module is relatively low, generally around 18°C; while the temperature requirement of the PCS is relatively high, generally around 30°C to 40°C. Therefore, it is difficult for a temperature control machine to simultaneously meet the temperature control requirements of these two types of temperature-controlled devices with different temperature requirements.

[0004] In order to save costs, reduce space and solve the above problems, for energy storage equipment, Figure 2 The structural diagram of the combination of liquid cooling of the battery module and air cooling of the energy storage converter shown is a commonly used temperature control solution at present, that is, only one temperature controller is used to control the temperature of the battery module, and a heat dissipation hole is opened in the shell of the PCS to connect with the external air, and the PCS is cooled by setting a fan 14. However, the disadvantage of this current temperature control solution is that when the ambient temperature is high in summer, it is difficult to effectively dissipate the heat of the PCS by air cooling; if there is dust in the external environment, it is also very easy to cause pollution to the internal components of the PCS. In addition, when the temperature is very low in winter, the temperature controller switches from cooling mode to heating mode to heat and keep the battery module warm, but there is only a fan on the PCS side, which cannot heat and keep the PCS warm. Summary of the invention

[0005] Based on the above problems, the present application provides a temperature control system and method, which can control the temperature of two devices to be temperature controlled by one temperature controller, and can also control the temperature of the second device to be temperature controlled by an air supply device. It can simultaneously meet the different temperature requirements of the two devices to be temperature controlled, achieve cooling and heat dissipation or heating and insulation, and the overall power consumption, cost, and volume of the equipment are not significantly increased.

[0053] Figure 3 A schematic structural diagram of a temperature control system according to an exemplary embodiment is shown.

[0054] like Figure 3 As shown, according to one aspect of the present application, a temperature control system is proposed, comprising: a temperature control machine 11, a pipeline 32, an air supply device 33, and at least two liquid temperature control devices including a first liquid temperature control device 34 and a second liquid temperature control device 35. Among them,

[0055] The first liquid temperature control device 34 is installed inside the first device to be temperature-controlled 36 , and the second liquid temperature control device 35 and the air supply device 33 are installed inside the second device to be temperature-controlled 37 .

[0056] The temperature control machine 11, the pipeline 32 and at least two liquid temperature control devices form a temperature control loop.

[0057] The temperature control machine 11 is used to perform temperature control on the first device to be temperature controlled 36 and the second device to be temperature controlled 37 through a temperature control loop.

[0058] The air supply device 33 is used to perform temperature control on the second device to be temperature-controlled 37 .

[0059] In this embodiment, the temperature control machine 11 may include a cooling mode and a heating mode. When the temperature control machine 11 is in the cooling mode, the temperature control machine 11 may cool and dissipate heat to the first device to be temperature controlled 36 and the second device to be temperature controlled 37 through the temperature control circuit, and may also cool and dissipate heat to the second device to be temperature controlled 37 through the air supply device 33. When the temperature control machine 11 is in the heating mode, the temperature control machine 11 may heat and keep warm the first device to be temperature controlled 36 and the second device to be temperature controlled 37 through the temperature control circuit, and may also heat and keep warm the second device to be temperature controlled 37 through the air supply device 33.

[0060] The pipeline 32 may include a water inlet pipeline and a water return pipeline. The liquid outlet 111 of the temperature control machine 11 is connected to one end of at least two liquid temperature control devices through the water inlet pipeline in the pipeline 32, and the liquid return port 112 of the temperature control machine 11 is connected to the other end of at least two liquid temperature control devices through the water return pipeline in the pipeline 32, forming a temperature control loop. There is a temperature control medium in the temperature control loop, and the temperature control medium includes but is not limited to pure water, a mixed liquid of water and other liquids, a gas, or a gas-liquid mixture, etc., for example, it can be a mixed liquid such as a 50% ethylene glycol solution.

[0061] The air supply device 33 may be a fan, specifically an AC fan, a DC fan, etc. The air supply device 33 may allow gas to circulate in the space of the second temperature-controlled device 37, thereby improving the heat exchange efficiency of the gas in the space between the second liquid temperature control device 35 and the second temperature-controlled device 37, and heating and keeping the second temperature-controlled device 37 warm.

[0062] The air supply device 33 can also improve the cold exchange efficiency of the gas in the space between the second liquid temperature control device 35 and the second device to be temperature controlled 37 , and cool and dissipate the heat of the second device to be temperature controlled 37 .

[0063] If the device to be temperature controlled is an energy storage device, the first device to be temperature controlled 36 may be a battery module in the energy storage device, and the second device to be temperature controlled 37 may be a PCS in the energy storage device. When the first device to be temperature controlled 36 is a battery module and the second device to be temperature controlled 37 is a PCS, the first device to be temperature controlled 36 and the second device to be temperature controlled 37 are two types of devices to be temperature controlled with different temperature control requirements. For example, the temperature control requirement of the first device to be temperature controlled 36 may be 18°C, and the temperature control requirement of the second device to be temperature controlled 37 may be 30°C to 40°C.

[0064] The first device to be temperature controlled 36 and the second device to be temperature controlled 37 may be two types of devices to be temperature controlled with different temperature control requirements, or may be two types of devices to be temperature controlled with the same temperature control requirements. For example, the temperature control requirements of the first device to be temperature controlled 36 and the second device to be temperature controlled 37 may both be 25° C., or may both be 10° C. to 20° C. When an electrical component 371 is provided inside the second device to be temperature controlled 37, the second liquid temperature control device 35 is not in direct contact with the electrical component 371 inside the second device to be temperature controlled 37 that is easily affected by water vapor, such as some power electronic components in the PCS.

[0065] Taking the first device to be temperature controlled 36 as a battery module, the temperature control requirement of the battery module is 18°C, and the second device to be temperature controlled 37 as a PCS, the temperature control requirement of the PCS is 30°C to 40°C as an example, the temperature control machine 11 in the temperature control system preferentially controls the outlet liquid temperature at the liquid outlet 111 of the temperature control machine 11 according to the temperature control requirement of the first device to be temperature controlled 36 (battery module) of 18°C. When the temperature control requirement of the first device to be temperature controlled 36 of 18°C ​​is reached, the temperature inside the second liquid temperature control device 35 is also 18°C. At this time, the temperature inside the second device to be temperature controlled 37 can be controlled by the air supply device 33 to meet 30°C to 40°C. In this embodiment, the combined use of the temperature control machine 11 and the air supply device 33 can be used to temperature control devices with different temperature requirements.

[0066] According to some embodiments, Figure 3As shown, in the above temperature control system, the first temperature-controlled device 36 and the second temperature-controlled device 37 are both provided with a housing 38 , and the housing 38 forms a sealed space. The air supply device 33 can be provided on the inner wall of the housing 38 .

[0067] Considering that if the second temperature-controlled device 37 is provided with electrical components, when the second temperature-controlled device 37 is temperature-controlled, condensed water is easily formed on the surface of the second liquid temperature-controlled device 35 inside the second temperature-controlled device 37, especially when the temperature controller 11 is in the cooling mode. The formed condensed water will affect the operation and service life of the electrical components 371 provided inside the second temperature-controlled device 37. In order to avoid the above-mentioned influence, Figure 3 As shown, according to some embodiments, in the above-mentioned temperature control system, a discharge pipe 39 is configured in the second device to be temperature controlled 37, which is used to discharge the condensed water formed by the second liquid temperature control device 35 out of the second device to be temperature controlled 37. When both the first device to be temperature controlled 36 and the second device to be temperature controlled 37 are provided with a shell 38, the discharge pipe 39 can discharge the condensed water formed on the second liquid temperature control device 35 to the outside of the shell 38 of the second device to be temperature controlled 37.

[0068] Figure 4 A schematic structural diagram of a second liquid temperature control device according to an exemplary embodiment is shown.

[0069] According to some embodiments, Figure 4 As shown, in the above-mentioned temperature control system, the second liquid temperature control device 35 is provided with fins 40, which can improve the temperature control effect of the air supply device 33 and the second liquid temperature control device 35 inside the second temperature-controlled device 37. The fins 40 can increase the contact area between the second liquid temperature control device 35 and the gas inside the second temperature-controlled device, improve the cold / heat exchange efficiency of the second liquid temperature control device 35, and thus improve the cooling and heat dissipation / heating and insulation effect.

[0070] According to some embodiments, Figure 3 As shown, in the above-mentioned temperature control system, a guide air duct is formed between the second liquid temperature control device 35 and the air supply device 33, which can improve the cold / heat exchange efficiency of the internal space of the second temperature-controlled device 37. When the air supply device 33 is working, the cold / heat of the second liquid temperature control device 35 is transferred to the space of the second temperature-controlled device 37, and the space of the second temperature-controlled device 37 and the electrical components 371 arranged inside the second temperature-controlled device 37 are cooled and dissipated / heated and kept warm.

[0071] According to some embodiments, in the above-mentioned temperature control system, one or more air supply devices 33 are provided. Each group of air supply devices 33 is provided with at least one. If the air supply device 33 is a fan, one or more fans may be provided. Each group of fans is provided with at least one. In this embodiment, the temperature control system can control the temperature inside the second device to be temperature controlled 37 to be not higher than the maximum operating temperature of the electrical component 371 provided inside the second device to be temperature controlled 37 and / or not lower than the dew point temperature inside the second device to be temperature controlled 37 by controlling the rotation speed of the air supply device 33 and / or the start and stop of the air supply device 33.

[0072] Figure 5 A schematic structural diagram of a single cabin of a second device to be temperature-controlled according to an exemplary embodiment is shown.

[0073] In this embodiment, if Figure 5 As shown, the above-mentioned temperature control system includes: air supply device 33, second liquid temperature control device 35, shell 38, guide air duct, and can also include: air cooling radiator 41, the air cooling radiator 41 can be a metal block, such as an aluminum block. The air cooling radiator 41 can be arranged inside the second temperature control device 37. In order to improve the temperature control effect of the second liquid temperature control device 35 and the air supply device 33 inside the second temperature control device 37, the air cooling radiator 41 can be used to install the electrical component 371 arranged inside the second temperature control device 37. Specifically, the electrical component 371 with a heat generation greater than the preset value, that is, the main heat generating electrical component 372 can be arranged in the air cooling radiator 41. And a fin 40 can be arranged on the side of the air cooling radiator 41 facing the second liquid temperature control device 35.

[0074] like Figure 5 As shown, when the air-cooling radiator 41 is included in the above-mentioned temperature control system, a guide air duct can be formed between the second liquid temperature control device 35, the air-cooling radiator 41 and the air supply device 33, so as to improve the cold / heat exchange efficiency between the second liquid temperature control device 35 and the air-cooling radiator 41. When the air supply device 33 is working, the cold / heat of the second liquid temperature control device 35 is transferred to the air-cooling radiator 41, so as to cool and dissipate heat / heat and keep warm the space of the second device to be temperature controlled 37 and the electrical components installed on the air-cooling radiator 41.

[0075] In this embodiment, if Figure 5As shown, the temperature control system may further include: a temperature measuring device 42 and a humidity measuring device 43. The temperature measuring device 42 and the humidity measuring device 43 may be arranged inside the second temperature-controlled device 37, and the temperature and humidity inside the second temperature-controlled device 37 may be monitored in real time. The temperature measuring device 42 may be arranged around the electrical component 371 arranged inside the second temperature-controlled device 37, and the temperature around the electrical component 371 may be monitored in real time. The humidity measuring device 43 may be arranged around the electrical component 371 arranged inside the second temperature-controlled device 37, and the humidity around the electrical component 371 may be monitored in real time.

[0076] When the second temperature-controlled device 37 is equipped with an air-cooled radiator 41, the temperature measuring device 42 and the humidity measuring device 43 can be configured on the air-cooled radiator 41 to facilitate real-time monitoring of the temperature (i.e., the temperature on the surface of the air-cooled radiator 41) and humidity (i.e., the humidity on the surface of the air-cooled radiator 41) around the main heat-generating electrical component 372.

[0077] The present application takes into account that when the second liquid temperature control device 35 leaks and sprays liquid, the liquid is sprayed onto the electrical component 371 set inside the second temperature control device 37, which will affect the operation and service life of the electrical component 371. In order to ensure the normal operation and long service life of the electrical component 371.

[0078] Figure 6 FIG. 2 shows a schematic diagram of the structure of a double-cabin body of a second temperature-controlled device according to an exemplary embodiment. Figure 6 As shown, the temperature control system of the present application further includes: a partition 44. The partition 44 divides the space of the second device to be temperature controlled 37 into two relatively independent cabins. The second liquid temperature control device 35 is arranged in one of the cabins, and the electrical component 371 arranged inside the second device to be temperature controlled 37 is arranged in the other cabin. The second liquid temperature control device 35 is separated from the electrical component 371. Based on the above scheme, when liquid leakage occurs in the second liquid temperature control device 35, the liquid will not be sprayed onto the electrical component 371 arranged inside the second device to be temperature controlled 37, which can improve the operating stability and longer service life of the electrical component 371.

[0079] In addition, it should be noted that Figure 6 The partition 44 in the structural diagram is used to separate the space of the second temperature-controlled device 37 into at least two relatively independent cabins, and the number of cabins is not limited.

[0080] When the temperature control system includes a partition, the second liquid temperature control device 35 can be set in one of the cabins, and the electrical component 371 set inside the second temperature control device 37 can be set in other cabins, which can prevent the second liquid temperature control device 35 from leaking and spraying, thereby preventing the operation and service life of the electrical component 371 set inside the second temperature control device 37 from being affected.

[0081] According to some embodiments, Figure 6 As shown, on the basis that the temperature control system includes the partition 44, the temperature control system may further include: an air-cooling radiator 41, which may be arranged inside the second device to be temperature-controlled 37, and is used to install the electrical component 371 arranged inside the second device to be temperature-controlled 37. The air-cooling radiator 41 may be embedded in the partition 44, and a fin 40 may be arranged on the side of the air-cooling radiator 41 facing the second liquid temperature control device 35. The fins arranged on the air-cooling radiator 41 have the same function as the fins arranged on the second liquid temperature control device 35, and may improve the temperature control effect of the air supply device 33 and the second liquid temperature control device 35 inside the second device to be temperature-controlled 37. The fins 40 may increase the contact area between the air-cooling radiator 41 and the gas inside the second device to be temperature-controlled, improve the cold / heat exchange efficiency, and thereby improve the cooling and heat dissipation / heating and insulation effect.

[0082] When the electrical component 371 arranged inside the second temperature-controlled device 37 is arranged in the air-cooled radiator 41 of other cabins, the embedded air-cooled radiator 41 is provided with fins 40 on the side facing the second liquid temperature control device 35, which is beneficial to improve the cold / heat exchange efficiency between the second liquid temperature control device 35 and the air-cooled radiator 41, and improve the temperature control effect of other cabins equipped with the electrical component 371.

[0083] In the present application, when one or more air supply devices 33 are provided, and the temperature control system does not include a partition 44, one or more air supply devices 33 can be arranged inside the second device to be temperature controlled 37, and can be specifically arranged on the inner wall of the shell 38. When one or more air supply devices 33 are provided, and the temperature control system includes a partition 44, one or more air supply devices 33 can be placed in one of the cabins where the second liquid temperature control device 35 is arranged in the second device to be temperature controlled 37. In addition, according to some embodiments, on the basis of the above-mentioned temperature control system including a partition 44, at least two groups of air supply devices 33 are provided, which are respectively installed in at least two cabins. That is, when more than one group of air supply devices 33 are provided, the air supply devices 33 are respectively installed in at least two cabins. Each independent cabin can be configured with an air supply device 33, which can improve the temperature control effect inside each cabin.

[0084] According to one aspect of the present application, a temperature control method is proposed, which is applied to the above-mentioned temperature control system. The inventive concept of the temperature control method is that the temperature controller preferentially controls the liquid outlet temperature at the liquid outlet of the temperature controller according to the temperature (temperature threshold) set according to the temperature control requirement of the device to be temperature controlled (i.e., the first device to be temperature controlled) that is not equipped with an air supply device, so that the temperature at the liquid inlet of the first liquid temperature control device to be temperature controlled reaches the temperature threshold.

[0085] When the temperature at the liquid inlet of the first liquid temperature control device of the first temperature-controlled device reaches the temperature threshold, the temperature at the liquid inlet of the second liquid temperature control device of the second temperature-controlled device also reaches the temperature threshold of the first temperature-controlled device. At this time, the rotation speed of the air supply device can be controlled to control the temperature inside the second temperature-controlled device (i.e., the temperature around the electrical components, if the temperature measuring device is configured on an air-cooled radiator, then the temperature on the surface of the air-cooled radiator) not higher than the maximum operating temperature of the electrical components set inside the second temperature-controlled device and / or not lower than the dew point temperature inside the second temperature-controlled device.

[0086] The temperature inside the second device to be temperature controlled (i.e., the temperature around the electrical components; if the temperature measuring device is arranged on an air-cooled radiator, the temperature on the surface of the air-cooled radiator) can also be controlled by starting and stopping the air supply device to be not higher than the maximum operating temperature of the electrical components arranged inside the second device to be temperature controlled and / or not lower than the dew point temperature inside the second device to be temperature controlled.

[0087] Figure 7 A schematic flow chart of a temperature control method according to an exemplary embodiment is shown. Figure 7 As shown, the temperature control method includes:

[0088] S101: The temperature controller controls the outlet temperature of the liquid at its outlet according to the temperature threshold, so that the temperature at the liquid inlet of the first liquid temperature control device of the first device to be temperature controlled reaches the temperature threshold.

[0089] In this embodiment, the temperature threshold is a temperature set according to the temperature control requirement of the first device to be temperature-controlled.

[0090] Figure 8 A schematic flow chart of a temperature control method according to another exemplary embodiment is shown.

[0091] According to some embodiments, Figure 8 As shown, the temperature control method further includes:

[0092] S201: Controlling the temperature inside the second temperature-controlled device by an air supply device to meet a preset condition.

[0093] According to some embodiments, in S201, controlling the temperature inside the second temperature-controlled device by the air supply device to meet a preset condition includes:

[0094] The temperature inside the second temperature-controlled device is controlled to meet the preset conditions by controlling the speed of the air supply device and / or starting and stopping the air supply device. In order to ensure the working safety of the air supply device itself, a maximum speed is set for the air supply device. The speed of the air supply device is less than or equal to the maximum speed.

[0095] According to some embodiments, when more than one group of air supply devices is provided, the temperature inside the second temperature-controlled device is controlled to meet a preset condition by controlling the rotation speed of the air supply device and / or starting and stopping the air supply device, including:

[0096] The temperature inside the second temperature-controlled device is controlled to meet a preset condition by individually controlling the rotation speed of each group of air supply devices and / or starting and stopping each group of air supply devices.

[0097] In this embodiment, when the space inside the second device to be temperature-controlled includes at least two cabins, and at least two groups of air supply devices are provided and respectively installed in at least two cabins, the rotation speed of each group of air supply devices in each cabin and / or the start and stop (number of groups or number) of each group of air supply devices in each cabin can be controlled to meet preset conditions by individually controlling the rotation speed of each group of air supply devices in each cabin.

[0098] In this embodiment, the preset condition is that the temperature inside the second temperature-controlled device is not higher than the maximum operating temperature of the electrical components arranged inside the second temperature-controlled device and / or is not lower than the dew point temperature inside the second temperature-controlled device. The dew point temperature is calculated based on the temperature measured by the temperature measuring device and the humidity measured by the humidity measuring device.

[0099] The temperature inside the second temperature-controlled device is the temperature measured by the temperature measuring device, and the temperature measuring device is arranged around the electrical components arranged inside the second temperature-controlled device, and the temperature inside the second temperature-controlled device is the temperature around the electrical components. When the second temperature-controlled device is equipped with an air-cooled radiator, the temperature measuring device can be arranged on the air-cooled radiator, and the temperature inside the second temperature-controlled device is the temperature around the electrical components to be heated (i.e., the temperature on the surface of the air-cooled radiator).

[0100] When the rotation speed of the air supply device is 0, there is no direct contact between the second liquid temperature control device and the electrical components arranged inside the second temperature control device. The thermal insulation of the gas inside the second temperature control device can basically ensure that the electrical components have a higher temperature.

[0101] In addition, an air-cooled radiator is arranged inside the second temperature-controlled device of the temperature control system, and when the electrical components arranged inside the second temperature-controlled device are installed on the air-cooled radiator, there is no direct contact between the second liquid temperature control device and the air-cooled radiator. Through the heat insulation of the gas inside the second temperature-controlled device, it can basically be ensured that the surface of the air-cooled radiator has a higher temperature, thereby ensuring that the electrical components have a higher temperature.

[0102] When the temperature controller is in cooling mode, the cold exchange effect between the second liquid temperature control device and the internal gas and air-cooled radiator of the second temperature control device can be improved by increasing the rotation speed of the air supply device and / or increasing the number of groups or numbers of air supply devices that are turned on, thereby improving the heat dissipation effect of the electrical components installed inside the second temperature control device and achieving cooling and heat dissipation.

[0103] When the temperature controller is in heating mode, the heat exchange effect between the second liquid temperature control device and the internal gas and air-cooled radiator of the second temperature control device can be improved by increasing the rotation speed of the air supply device and / or increasing the number of groups or numbers of air supply devices that are turned on, thereby improving the heating effect of the electrical components installed inside the second temperature control device and achieving heating and heat preservation.

[0104] For example, when the outside environment is very low in winter (for example, 4°C), the temperature controller is in heating mode to ensure that the temperature of the temperature-controlled medium of the first liquid temperature-controlled device entering the first temperature-controlled device is still 18°C, so that the first temperature-controlled device can be kept warm. At this time, the temperature of the temperature-controlled medium of the second liquid temperature-controlled device entering the second temperature-controlled device is also 18°C, and the air supply device can bring heat to the electrical components installed inside the second temperature-controlled device. The higher the speed of the air supply device or the more the number of operations, the greater the wind speed, and the better the heating and heat preservation effect of the electrical components installed inside the second temperature-controlled device.
