Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to an anti-condensation control method, a liquid cooling source device, and a computer-readable storage medium. Background Technology

[0002] As the spatial integration of electronic devices increases, the heat flux density of components continues to rise, placing increasingly higher demands on the heat dissipation of electronic devices. Traditional air-based cooling methods are insufficient to meet these needs. Liquid cooling, due to its powerful heat exchange capacity, is gradually becoming the preferred method for heat dissipation in integrated devices.

[0003] Condensation easily forms when air comes into contact with a surface below its dew point temperature. For electronic equipment, condensation can pose electrical safety risks. In areas with high humidity and significant temperature fluctuations where liquid cooling sources are used, anti-condensation measures are particularly important. Summary of the Invention

[0004] In order to solve the technical problem of condensation during equipment heat dissipation in the prior art, the present invention proposes an anti-condensation control method, a liquid cooling source device, and a computer-readable storage medium.

[0005] The technical solution adopted in this invention is:

[0006] This invention proposes a method for preventing condensation control, comprising the following steps:

[0007] After receiving the start command, the equipment selects to turn on the corresponding number of refrigeration modules according to the preset start range where the current liquid supply temperature is located;

[0008] Determine whether the liquid supply setting temperature of the refrigeration module is greater than or equal to the current dew point temperature. If not, modify the liquid supply setting temperature to be equal to or higher than the dew point temperature. If yes, continue to the next step.

[0009] Adjust the number of cooling modules according to the current liquid supply temperature.

[0010] The above-mentioned adjustment of the number of refrigeration modules based on the current liquid supply temperature specifically includes the following steps:

[0011] Determine the current liquid supply temperature within the set temperature deviation range;

[0012] The number of refrigeration modules that are turned on is adjusted according to the judgment or control logic corresponding to the set temperature deviation range.

[0013] Specifically, the temperature deviation range includes a first deviation range, a second deviation range, a third deviation range, a fourth deviation range, and a fifth deviation range, with the corresponding temperature values ​​decreasing sequentially.

[0014] Furthermore, the judgment logic corresponding to the first deviation setting range is as follows: determine whether the liquid supply cooling rate is less than or equal to the first preset cooling rate. If yes, increase the number of refrigeration modules that are turned on; otherwise, maintain the current number of refrigeration modules that are turned on.

[0015] Furthermore, the judgment logic corresponding to the second deviation setting range is: to determine whether the liquid supply cooling rate is greater than the first preset cooling rate;

[0016] If so, reduce the number of cooling modules that are turned on;

[0017] If not, determine whether the liquid supply cooling rate is less than or equal to the first preset cooling rate and greater than n times the first preset rate, where n is less than 1. If yes, the number of refrigeration modules turned on remains unchanged; otherwise, the number of refrigeration modules turned on is increased.

[0018] Furthermore, the control logic corresponding to the third deviation setting range is: to keep the number of refrigeration modules turned on constant. The control logic corresponding to the fourth deviation setting range is: to reduce the number of refrigeration modules turned on. The control logic corresponding to the fifth deviation setting range is: to shut down all refrigeration modules for emergency shutdown.

[0019] Specifically, increasing or decreasing the number of refrigeration modules that are turned on is done by sequentially increasing or decreasing the number of refrigeration modules that are turned on according to a preset order and a preset time interval.

[0020] The present invention also proposes a liquid cooling source device, including multiple refrigeration modules, which uses the above-mentioned anti-condensation control method to prevent cooling condensation.

[0021] The present invention also proposes a computer-readable storage medium for storing a computer program, which executes the above-described anti-condensation control method when running.

[0022] Compared with existing technologies, this invention is mainly applied to liquid cooling source equipment with multiple cooling modules. By first turning on the corresponding number of cooling modules, the heat dissipation demand of the equipment is roughly matched with the cooling demand of the liquid cooling source equipment. Then, by adjusting the current liquid supply setting temperature of the cooling modules, the real-time liquid supply temperature will not be lower than the current dew point temperature, thus avoiding condensation in the liquid cooling source equipment. Attached Figure Description

[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] Figure 1This is a flowchart of an embodiment of the present invention. Detailed Implementation

[0025] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] As the spatial integration of electronic devices increases, the heat flux density of components continues to rise, placing increasingly higher demands on the heat dissipation of electronic devices. Traditional air-based cooling methods are insufficient to meet these needs. Liquid cooling, due to its powerful heat exchange capacity, is gradually becoming the preferred method for heat dissipation in integrated devices.

[0028] Condensation easily occurs when air comes into contact with a surface below its dew point temperature. For electronic equipment, condensation can pose electrical safety risks. In areas with high humidity and significant temperature fluctuations where liquid cooling sources are used, anti-condensation measures are particularly important. This invention proposes a method to prevent condensation on the surface of cooled equipment, thus ensuring its electrical safety.

[0029] like Figure 1 As shown, this invention proposes a method for preventing condensation control, which specifically includes the following steps:

[0030] After receiving the power-on command, specifically the power-on command for the cooling module, the liquid supply pump, valves and other components are turned on in sequence. Then, according to the preset power-on range of the current liquid supply temperature, the corresponding number of cooling modules are turned on. After the first preset time, the cooling modules are turned on in sequence at certain time intervals. The liquid supply temperature is the temperature at which the cooling pipe enters the equipment, which can reflect the heat dissipation needs of the cooled equipment in real time.

[0031] Determine whether the current liquid supply setting temperature of the refrigeration module is greater than or equal to the current dew point temperature. If not, modify the liquid supply setting temperature to be equal to or higher than the dew point temperature. If yes, continue to the next step.

[0032] After running for a preset time, the number of cooling modules is adjusted according to the current liquid supply temperature. This invention first activates the corresponding number of cooling modules to roughly match the heat dissipation demand with the cooling demand, and then adjusts the current liquid supply setting temperature of the cooling modules to ensure that the real-time liquid supply temperature will not be lower than the current dew point temperature, thus preventing condensation from occurring in the equipment.

[0033] For ease of description, the liquid supply set temperature is specifically represented as Ts, the current liquid supply temperature is specifically represented as Td, the first preset cooling rate is specifically represented as ΔTt1, and the current liquid supply cooling rate is specifically represented as ΔTt.

[0034] In a specific embodiment, selecting the corresponding number of refrigeration modules to be activated based on the preset start-up range of the current liquid supply temperature is as follows:

[0035] The module has two preset operating temperatures: Tk1 and Tk2, where Tk1 > Tk2. The first preset operating range is defined as Td > Tk1, the second as Tk1 ≥ Td > Tk2, and the third as Tk2 ≥ Td. Each preset operating range corresponds to a different number of refrigeration modules that are activated. The higher the temperature value of the preset operating range, the more refrigeration modules are activated. For example, the first preset operating range activates 1X modules, the second as 2X modules, and the third as 3X modules.

[0036] The above-mentioned adjustment of the number of refrigeration modules based on the current liquid supply temperature specifically includes the following steps:

[0037] Determine the current liquid supply temperature within the set temperature deviation range;

[0038] The number of refrigeration modules activated is adjusted according to the judgment or control logic corresponding to the set temperature deviation range, so that the cooling capacity corresponding to the number of refrigeration modules activated can match the actual heat dissipation needs of the equipment in real time.

[0039] The temperature deviation range is specifically set as follows: a first deviation range, a second deviation range, a third deviation range, a fourth deviation range, and a fifth deviation range, with the corresponding temperature values ​​decreasing sequentially and continuously.

[0040] Specifically, the first deviation setting range is [Ts+ΔTc, +∞), that is, when Td≥Ts+ΔTc is within the first deviation setting range, the specific judgment logic of the first deviation setting range is: determine whether the liquid supply cooling rate is less than or equal to the first preset cooling rate, that is, whether ΔTt≤ΔTt1 is true. If yes, increase the number of refrigeration modules turned on in sequence, indicating that the temperature is too high and the cooling rate is insufficient. If no, maintain the current number of refrigeration modules turned on.

[0041] Specifically, the second deviation setting range is (Ts+ΔTc1, Ts+ΔTc), that is, when Ts+ΔTc>Td>Ts+ΔTc1, it is within the second deviation setting range. The specific judgment logic for the second deviation setting range is as follows:

[0042] Determine whether the current liquid supply cooling rate is greater than the first preset cooling rate, i.e., whether ΔTt>ΔTt1 holds true;

[0043] If so, one cooling module will be turned off every second preset time interval;

[0044] If not, determine whether the liquid supply cooling rate is less than or equal to the first preset cooling rate and greater than a multiple of the first preset rate, i.e., nTt1≤ΔTt≤ΔTt1, where n is less than 1; if yes, the number of cooling modules turned on remains unchanged; if no, the number of cooling modules turned on increases once every second preset time interval, indicating that the cooling rate is insufficient and more cooling modules need to be turned on to avoid excessively high temperatures later.

[0045] In specific embodiments, n can be 0.4, 0.5, etc., and can be set according to actual needs.

[0046] Specifically, the third deviation setting range is [Ts-ΔTc2, Ts+ΔTc1], that is, when Ts-ΔTc2<Td≤Ts+ΔTc1, it is within the third deviation setting range. The specific control logic of the third deviation setting range is to keep the number of current refrigeration modules turned on unchanged.

[0047] Specifically, the fourth deviation setting range is (Ts-ΔTc3, Ts-ΔTc2], that is, when Ts-ΔTc3<Td≤Ts-ΔTc2, it is within the fourth deviation setting range. The specific control logic of the fourth deviation setting range is: shut down one cooling module every second preset time interval.

[0048] Specifically, the fifth deviation setting range is Td < Ts - ΔTc3. If the temperature is too low, the machine will be shut down immediately to prevent condensation from occurring on the equipment.

[0049] The above ΔTt = (Tt1 - Tt2) / (t2 - t1) means that Tt2 corresponds to the liquid supply temperature at time t2, and Tt1 corresponds to the liquid supply temperature at time t1.

[0050] The specific steps to increase or decrease the number of refrigeration modules in operation are as follows: the number of refrigeration modules in operation is increased or decreased sequentially according to a preset order and a second preset time interval. Each time, one or two modules can be turned on, which can be adjusted according to the actual situation.

[0051] The present invention also proposes a liquid cooling source device for cooling electronic devices or devices that require heat dissipation. Specifically, the liquid cooling source device is a multi-module liquid cooling source refrigeration system, which includes multiple refrigeration modules.

[0052] A refrigeration module specifically refers to a refrigeration system unit, which includes components such as compressors, heat exchangers, and throttling elements. Multiple refrigeration modules cool the coolant (which can be water) and then connect in parallel through pipelines, eventually converging into the main pipeline to supply cooling to electronic equipment. That is, the temperature of the coolant in the main pipeline is the supply temperature.

[0053] The present invention also proposes a computer-readable storage medium for storing a computer program, which executes the above-described anti-condensation control method when the computer program is run.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0056] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0057] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
