Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling units, and in particular to a liquid cooling unit with a self-cleaning condenser and a control method thereof. Background Art

[0002] With the continuous development of energy storage technology, energy storage equipment is increasingly being used in various fields. However, energy storage equipment usually needs to operate in harsh environments, such as high temperature, high humidity, and dusty environments. In such an environment, the condenser of the liquid cooling unit, as an important component of the energy storage equipment, is easily affected by dust.

[0003] The condenser is a key component for heat exchange in a liquid cooling unit. During normal operation, the condenser dissipates heat from the refrigeration system by exchanging heat with the surrounding air. However, when a large amount of dust accumulates on the surface of the condenser, it will increase the air suction resistance and cause insufficient suction force, thus affecting the heat exchange effect. This will not only reduce the cooling efficiency of the liquid cooling unit, but may also cause the temperature of the energy storage device to rise, affecting its performance and life.

[0004] In addition, in the actual application of energy storage equipment, in many cases, the installation location is relatively remote or the space is limited, and it is very inconvenient to manually clean the dust on the condenser. This not only increases the maintenance cost, but may also cause equipment failure due to untimely cleaning. Summary of the invention

[0012] According to the technical solution provided in the embodiment of the present application, the self-cleaning module also includes a collection component electrically connected to the control module, and the collection component is used to obtain the dust accumulation degree of the condenser.

[0013] In a second aspect, the present application proposes a control method for a liquid cooling unit with a self-cleaning condenser, which is implemented based on the liquid cooling unit with a self-cleaning condenser as described above, and includes the following steps: When receiving a power-on signal of the liquid cooling unit, the accumulated running time of the liquid cooling unit is recorded in real time; and the blowing port is controlled to blow air to the condenser, and the blowing is stopped after a first preset time; If the accumulated running time reaches a second preset time and the compressor and the fan both stop working, the waiting time starts to be recorded; the refrigeration module also includes the fan, which is used in conjunction with the condenser; If the waiting time reaches the third preset time and the compressor and the fan are not restarted, the air outlet is controlled to blow air to the condenser, and the blowing is stopped after a fourth preset time; wherein the fourth preset time is the same as or different from the first preset time.

[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Example 1 As mentioned in the background technology, in view of the problems in the prior art, the present application proposes a liquid cooling unit with a self-cleaning condenser, comprising: A housing having an installation space therein; A refrigeration module, the refrigeration module is arranged in the installation space, and the refrigeration module includes a refrigeration cycle formed by a compressor, a condenser 1, an evaporator and an expansion valve connected in series through pipelines; A self-cleaning module, the self-cleaning module includes at least one blowing component and a control module electrically connected to each of the blowing components, the blowing component is arranged in the installation space and on the side of the condenser 1, and the blowing component has a blowing port 5 facing the side of the condenser 1; the control module is used to control the blowing port 5 to blow air toward the side of the condenser 1 according to a preset time interval, and / or the operating status of the refrigeration module, and / or the dust accumulation degree of the condenser 1.

[0023] Specifically, the shell serves as the external protective structure of the entire liquid cooling unit and is installed in a suitable position, usually near an energy storage device or a device that needs to be cooled. The refrigeration module is installed in the installation space inside the shell, and the compressor, condenser 1, evaporator and expansion valve are connected by pipes and arranged in the order of the refrigeration cycle. The blowing component in the self-cleaning module is installed on the side of the condenser 1, and the control module can be installed in a suitable position inside the shell to facilitate connection and control with the blowing component.

[0024] Specifically, the refrigeration module realizes the cooling function through a refrigeration cycle consisting of a compressor, a condenser 1, an evaporator and an expansion valve. The control module of the self-cleaning module controls the blowing assembly to blow air to the side of the condenser 1 according to a preset time interval, the operating state of the refrigeration module or the dust accumulation degree of the condenser 1, so as to blow away the dust on the condenser 1 and realize the self-cleaning function.

[0025] Specifically, the installation space in the shell is divided into two layers of space, front and back. The front layer of space is mainly used to install the refrigeration module, including components such as the compressor, condenser 1, evaporator and expansion valve, and the rear layer of space is used to install the self-cleaning module and the control module. This layout allows the blowing port 5 of the blowing assembly of the self-cleaning module to blow air vertically toward the side of the condenser 1, and the number of blowing assemblies is determined according to the size of the condenser 1 to be cleaned. When the condenser 1 is large in size, the blowing port 5 of one blowing assembly cannot fully cover the entire side of the condenser 1. In this case, multiple blowing assemblies can be set. If the condenser 1 is small in size, the blowing port 5 of one blowing assembly is sufficient to cover the entire side of the condenser 1, then only one blowing assembly is required.

[0026] In a preferred embodiment, a mounting bracket 3 is provided on the side of the condenser 1; the blowing assembly includes an air pump 2 installed on the mounting bracket 3, and a blowing duct 4 connected to the air outlet of the air pump 2, and the end of the blowing duct 4 away from the air outlet is the blowing port 5.

[0027] Specifically, the mounting bracket 3 is made of stainless steel, which has high strength and stability. Figure 1 As shown, the mounting bracket 3 can be a platform-type bracket, or a frame structure formed by two vertical columns and a plurality of horizontal cross bars. The vertical columns are fixed to the inner wall of the shell, and the horizontal cross bars are used to install the air pump 2 and other components. The mounting bracket 3 is installed on the side of the condenser 1, and a certain distance is maintained from the condenser 1 to facilitate air circulation and heat dissipation. The height and width of the mounting bracket 3 can be adjusted according to the size of the condenser 1 to ensure that the air pump 2 can be firmly supported.

[0028] Specifically, the blowing duct 4 extends outward away from the air outlet end to form a trumpet-shaped blowing port 5, which can increase the blowing area and ensure that the wind blowing toward the condenser 1 covers a larger area.

[0029] In a preferred embodiment, the mounting bracket 3 is connected to a bracket 6 near the condenser 1 side, the bracket 6 extends toward the condenser 1 side, the bracket 6 has a first mounting groove, and the blowing duct 4 is embedded in the first mounting groove.

[0030] Specifically, the bracket 6 is made of high-strength plastic material, which has certain elasticity and wear resistance. The bracket 6 is installed on the mounting bracket 3. The bracket 6 can be a plurality of support columns arranged along the extension direction of the blowing duct. Each support column is vertically connected with a U-shaped groove for installing the blowing duct 4 to prevent it from shaking during operation. The bracket 6 is installed on the side of the mounting bracket 3 close to the condenser 1 and extends toward the condenser 1. The length and width of the bracket 6 can be adjusted according to the size of the blowing duct 4 to ensure that the blowing duct 4 can be firmly installed.

[0031] Specifically, the mounting bracket 3 is fixed to the inner wall of the housing by bolts to ensure the stability of the mounting bracket 3. The support column of the bracket 6 is fixed to the mounting bracket 3 by bolts or welding to ensure the firmness of the bracket 6. The blowing duct 4 is embedded in the U-shaped groove of the bracket 6 and fixed by a clamping device to ensure that the blowing duct 4 will not fall off or shake during operation.

[0032] In a preferred embodiment, the vertical distance between the blowing port 5 and the side of the condenser 1 is obtained through condenser 1 related parameters of the condenser 1 and blowing related parameters of the blowing assembly, wherein the condenser 1 related parameters at least include the aspect ratio of the condenser 1, and the blowing related parameters at least include the power of the air pump 2 and the length of the blowing pipe 4.

[0033] Specifically, the vertical distance between the air outlet 5 and the condenser 1 will directly affect the coverage of the wind. If the distance is too close, the wind will be concentrated in a smaller area and cannot effectively cover a larger area of ​​the surface of the condenser 1; if the distance is too far, although the coverage area may increase, the wind will decay rapidly, resulting in poor cleaning effect.

[0034] Specifically, for a common combination of a condenser 1 and an air pump 2, the vertical distance between the air outlet 5 and the condenser 1 can be limited to between 10 and 30 centimeters. Within this range, it can be ensured that the wind has a certain diffusion space, so that the air outlet 5 can cover a large area of ​​the surface of the condenser 1, and the wind force will not be too much attenuated to lose the self-cleaning effect. For an air pump 2 with relatively low power (such as less than 500 watts), the distance can be appropriately reduced to 10-20 centimeters. In this way, when the wind force is relatively weak, it can be ensured that the wind can be concentrated on the surface of the condenser 1 to achieve a better cleaning effect. When the air pump 2 has a large power (such as greater than 1000 watts), the distance can be appropriately increased to 20-30 centimeters. At this time, a higher wind speed can still maintain sufficient cleaning ability at a longer distance. If the condenser 1 is flat and the ratio of length to height is greater than 3:1, the distance can be appropriately increased by 5-10 centimeters. For example, for a flat condenser 1 of 1 meter in length and 0.3 meter in height, the distance can be increased to 15 - 30 cm (for a low-power air pump 2) and 25 - 40 cm (for a high-power air pump 2) based on the distance corresponding to the power of the air pump 2, to ensure that the wind can evenly cover the entire surface of the condenser 1. For a three-dimensional condenser 1, such as a cube or a condenser 1 close to a cube, the distance can be set according to the general range recommended above, or slightly reduced within the range of 10 - 30 cm according to the power of the air pump 2, such as 8 - 25 cm, so that the wind can be concentrated on the surface of the condenser 1, avoiding excessive diffusion of wind force and resulting in a decrease in the cleaning effect, and can more effectively cover the surface of the condenser 1.

[0035] Specifically, by considering the size and shape of the condenser 1 and the performance parameters of the blowing assembly, the vertical distance between the blowing port 5 and the side of the condenser 1 is determined to ensure the best blowing effect. The appropriate vertical distance can make the blown wind evenly cover the surface of the condenser 1, while avoiding the wind force being too small or too large, which affects the self-cleaning effect.

[0036] In a preferred embodiment, a vent is provided on the side of the condenser 1 away from the blowing assembly, opposite to the blowing assembly and connected to the installation space. The wind blown out of the blowing port 5 passes through the condenser 1 to form dusty wind, and the vent is used to discharge the dusty wind.

[0037] Specifically, the blowing direction of the blowing port 5 of the blowing assembly is the same as the direction of the airflow generated by the fan. For example, if the fan blows air upward from the bottom of the condenser 1, the blowing port 5 of the blowing assembly should also be set to blow upward from the bottom. In this way, the airflow blown out of the blowing assembly can cooperate with the airflow of the fan, enhance the overall air flow, and help to more effectively remove the heat and dust emitted by the condenser 1. When the same-direction design is difficult to achieve, the blowing port 5 of the blowing assembly can be set to be at a certain angle (such as 30°-60°) to the airflow direction of the fan. Through the guide plate or the special air outlet shape, the airflow blown out of the blowing assembly can be obliquely integrated into the mainstream airflow generated by the fan. For example, the wind blown out by the blowing assembly arranged on the side of the condenser 1 can be guided by the guide plate so that it can smoothly merge with the vertical airflow generated by the fan at the top or bottom of the condenser 1.

[0038] Specifically, the blowing assembly blows air toward the side of the condenser 1, blows up the dust on the condenser 1, and forms dusty wind. The vent and the blowing assembly are arranged relative to each other, so as to form a direct airflow channel, so that the dusty wind can be smoothly discharged from the installation space in the shell. This can prevent dust from accumulating in the shell and affecting the performance and life of the equipment. The relative arrangement can make the airflow smoother, reduce the resistance of the airflow, and improve the discharge efficiency of the dusty wind. If the position of the vent and the blowing assembly is unreasonable, it may cause airflow turbulence and affect the discharge effect.

[0039] In a preferred embodiment, the area of ​​the ventilation opening is greater than or equal to the area of ​​the blowing opening 5 .

[0040] Specifically, the larger the area of ​​the vent, the smaller the wind resistance, and the dusty wind can be discharged more smoothly. If the area of ​​the vent is too small, it may cause increased wind resistance, affecting the discharge efficiency, and may even cause some dust to accumulate at the vent, blocking the vent. During the operation of the liquid cooling unit, the degree of dust accumulation on the condenser 1 may change continuously, requiring blowing of different intensities for cleaning. A large vent area can adapt to blowing of different intensities, ensuring that the dusty wind can be discharged in time, and the self-cleaning effect will not be affected by the small vent area. A larger vent area can increase the air circulation in the shell and improve the heat dissipation effect. This is very important for the normal operation of the liquid cooling unit, especially in a high temperature environment, which can effectively reduce the temperature of the equipment and improve the reliability of the equipment.

[0041] In a preferred embodiment, the self-cleaning module further includes a collection component electrically connected to the control module, and the collection component is used to obtain the dust accumulation degree of the condenser 1.

[0042] Specifically, an optical dust sensor and a computing module are used as acquisition components, and the optical sensor is installed on the side edge of the condenser 1, about 2-5 cm away from the edge. For example, when the condenser 1 is a rectangular parallelepiped, one of the longer side edges is selected, and the probe part of the optical sensor is directed toward the surface of the condenser 1. The principle of the optical dust sensor is based on the scattering or blocking of light. When dust adheres to the surface of the condenser 1, it will affect the propagation of light. There is a light-emitting diode (LED) and a photodetector inside the sensor. The light emitted by the LED is irradiated onto the surface of the condenser 1. When dust accumulates, the intensity of the reflected light or scattered light will change, and the light signal received by the photodetector will also change accordingly. The photodetector sends the received light signal to the computing module, and a mapping comparison table is stored in the computing module. The mapping comparison table includes multiple groups of light signal intensities and the dust accumulation degree on the surface of the condenser 1 corresponding to each group of light signal intensities. After the computing module receives the current light signal intensity, it compares the mapping comparison table to obtain the corresponding dust accumulation degree.

[0043] Example 2 Based on Example 1, this example proposes a control method for a liquid cooling unit capable of self-cleaning a condenser, such as Figure 2 As shown, the following steps are included: S1. When receiving a power-on signal of the liquid cooling unit, the accumulated running time of the liquid cooling unit is recorded in real time; and the air blowing port 5 is controlled to blow air to the condenser 1, and the air blowing is stopped after a first preset time; optionally, the first preset time is 3 minutes; Specifically, when the liquid cooling unit is powered on, the condenser 1 is blown and cleaned for a first preset time (3 minutes). This can timely remove dust and other impurities that may have accumulated in the condenser 1 during shutdown, ensuring that the liquid cooling unit can be put into operation with a relatively clean condenser 1 from the start, improving heat exchange efficiency, and avoiding degradation of initial operating performance due to dust accumulation.

[0044] S2. If the accumulated running time reaches a second preset time and the compressor and the fan both stop working, start recording the waiting time; the refrigeration module also includes the fan, which is used in conjunction with the condenser 1; optionally, the second preset time is 2 hours; Specifically, this regular cleaning method can promptly handle the dust accumulated on the condenser 1 after the liquid cooling unit has been running for a period of time, ensuring that the condenser 1 always maintains good heat exchange performance, thereby maintaining the efficient operation of the liquid cooling unit.

[0045] S3. If the waiting time reaches a third preset time and the compressor and the fan are not restarted, the air outlet 5 is controlled to blow air to the condenser 1 and stop blowing air after a fourth preset time; wherein the fourth preset time is the same as or different from the first preset time. Optionally, the third preset time is 5 minutes and the fourth preset time is 3 minutes.

[0046] Specifically, the air outlet 5 is controlled to blow air toward the condenser 1, and after the blowing stops after the fourth preset time, the accumulated running time of the refrigeration system is reset to zero, and it is used as a self-cleaning cycle. The timing is restarted to obtain a new round of accumulated running time, and steps S2-S3 are repeated until the liquid cooling unit is powered off.

[0047] Specifically, the present embodiment fully considers the operating status of the compressor and the fan in the refrigeration module. Cleaning is performed only when both the compressor and the fan stop working and the waiting time condition is met, avoiding interference and risks that may be caused by cleaning during the operation of the refrigeration system. This ensures that the cleaning operation will not affect the normal refrigeration function of the liquid cooling unit, and effective cleaning can be performed at the right time. The first preset time, the second preset time, the third preset time and the fourth preset time can be adjusted according to actual conditions. For example, if the liquid cooling unit is operating in a dusty environment, the second preset time and the third preset time can be appropriately shortened to increase the frequency of cleaning; if the dust accumulation rate of the condenser 1 is slow, these time periods can be appropriately extended to save energy and reduce the operating wear of the blowing assembly. This flexibility enables the solution to adapt to different working environments and usage requirements.

[0048] Furthermore, the method further comprises the following steps: Based on the collection component, a dust accumulation time series is obtained, the dust accumulation time series includes multiple groups of collection moments and dust accumulation degrees corresponding to each group of collection moments, each collection moment has a mark position, and the mark position is marked as uncleaned and clean; Based on the dust accumulation time series, a plurality of first sequences are obtained, wherein the first sequence is composed of a plurality of consecutive collection moments marked as uncleaned, and dust accumulation degrees corresponding to the collection moments; Obtain a previous first sequence close to the current power-on signal, use the first sequence as a target sequence, and obtain a dust accumulation rate according to the target sequence; wherein the dust accumulation rate is used to characterize the amount of dust in the environment in which the liquid cooling unit is running; the more dust there is, the faster the dust accumulation rate is; According to the dust accumulation rate, the first preset time length, the second preset time length, the third preset time length and the fourth preset time length are dynamically adjusted; wherein, the faster the dust accumulation rate, the longer the first preset time length, the shorter the second preset time length, the shorter the third preset time length, and the longer the fourth preset time length.

[0049] In a preferred embodiment, the controlling the blowing port 5 to blow air toward the condenser 1 and stopping blowing air after a first preset time period further includes the following steps: Obtaining the real-time inlet and outlet temperature difference of the condenser 1 in real time; If the accumulated running time reaches the second preset time and the compressor and the fan both stop working, the waiting time is recorded, which specifically includes the following steps: If the real-time inlet and outlet temperature difference is less than or equal to the first preset threshold, if the accumulated running time reaches the second preset time, and the compressor and the fan both stop working, then start recording the waiting time; Specifically, if the real-time inlet and outlet temperature difference is less than or equal to the first preset threshold, it means that the heat exchange performance of the condenser 1 is good, and at this time, it can be operated according to the normal self-cleaning logic.

[0050] After obtaining the real-time inlet and outlet temperature difference of the condenser 1, the following steps are also included: If the real-time inlet and outlet temperature difference is greater than the first preset threshold, the air outlet 5 is controlled to blow air toward the condenser 1 .

[0051] Specifically, this embodiment can more accurately judge the heat exchange performance of the condenser 1 by real-time monitoring of the inlet and outlet temperature difference of the condenser 1. When the temperature difference is large, it indicates that the heat exchange effect of the condenser 1 may be greatly affected, which is probably caused by dust accumulation and other reasons. At this time, you cannot wait until the second preset time, but should immediately start the blowing component for cleaning, which can solve the dust accumulation problem of the condenser 1 more targetedly and improve the efficiency and effect of cleaning.

[0052] In a preferred embodiment, the controlling the blowing port 5 to blow air toward the condenser 1 and before stopping blowing air after the first preset time period further includes determining the first preset time period; Determining the first preset duration specifically includes the following steps: Obtaining the real-time dust accumulation degree of the current condenser 1; Retrieve the blowing parameter table to obtain the initial blowing time corresponding to the real-time dust accumulation degree, and use the initial blowing time corresponding to the dust accumulation degree as the first preset time; the blowing parameter table includes multiple groups of dust accumulation degrees, and the initial blowing time corresponding to each group of dust accumulation degrees.

[0053] Specifically, when the liquid cooling unit starts to operate, if the dust accumulation degree obtained according to the collection component is high, the first preset time length obtained is also longer, and the initial cleaning of the dust accumulation in the condenser 1 is more effective to ensure the operating effect.
