The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, it is to be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like refer to orientations or positional relationships based on those shown in the drawings, merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be taken as limiting the present application.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.

In the description of the present application, it should be noted that, unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, a fixed connection, a detachable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The main cooling and heat dissipation modes of electronic devices (such as a frequency converter) in a frequency conversion electric control cabinet of the large frequency conversion water chilling unit of the existing central air conditioner comprise air cooling, water cooling and refrigerant cooling. The air-cooled heat dissipation efficiency is low, the volume is large, the cost is high, and dust is easy to accumulate; the water cooling system is complex, easy to scale and high in cost; the refrigerant cooling heat dissipation efficiency is high, the structure is simple and reliable, the volume is small, and the cost is low, so that refrigerant cooling is adopted for the variable-frequency electric control cabinet which is preferred at present.

When the frequency conversion electric control cabinet is cooled by adopting a refrigerant in the related art, the refrigerant pipeline is connected with the evaporator, so that the refrigerant in the refrigerant pipeline is in a low-temperature and low-pressure state, the temperature value of the refrigerant is low, and the problems that the frequency converter is easy to dewe to cause an electrical short circuit fault and the like exist. Besides the frequency converter, other electronic devices such as reactors and transformers arranged in the frequency conversion electric control cabinet can generate heat in a large amount in the operation process, and the frequency conversion electric control cabinet needs to be cooled. However, when other electronic devices in the variable-frequency electric control cabinet are cooled by the refrigerant, the temperature of the generated cold air is lower due to the adoption of the low-pressure low-temperature refrigerant for cooling. When cold wind blows parts (such as sheet metal, supports and the like) that do not generate heat in the cabinet, can cause these parts surface temperature that do not generate heat to hang down excessively, in the environment of damp and hot and under the automatically controlled cabinet box of frequency conversion sealed not tight condition, in the high temperature high humidity's air entering cabinet in the automatically controlled cabinet external environment, these parts surfaces that do not generate heat just easily dewfall and drip, cause other electronic device in the automatically controlled cabinet of frequency conversion to take place electric short circuit trouble and incident easily.

Based on this, this application embodiment provides a cooling system, through passageway one end and the condenser intercommunication that sets up in the cold drawing, the passageway other end and the flash vessel intercommunication in the cold drawing, not with the evaporimeter intercommunication, so, the refrigerant that gets into passageway in the cold drawing is in medium temperature middling pressure state, also the temperature value of the refrigerant of passageway in the cold drawing can not be too high also can not be too low, when can make the cold drawing effectively cool down to electron device, the cold drawing can not be because the temperature value of refrigerant crosses low and the dewfall, the probability that electron device produced electrical short circuit trouble in the automatically controlled cabinet has been reduced.

For the sake of understanding, the basic concepts of some terms or techniques related to the embodiments of the present invention will be briefly described and explained.

Refrigerant: a substance which is easily changed into gas by heat absorption and changed into liquid by heat release. In the cooling system, heat energy is transferred through evaporation and condensation of a refrigerant, and a refrigeration effect is generated.

FIG. 1 is a schematic diagram of the components of a cooling system provided in accordance with an exemplary embodiment of the present application. As shown in fig. 1, the cooling system 1 includes a cabinet 10, electronics 11, a cold plate 12, a compressor 13, a condenser 14, a flash evaporator 19, an evaporator 20, and a controller 50 (not shown in fig. 1).

In some embodiments, the cabinet 10 may be an electronic control cabinet. The electric control cabinet is a control cabinet (box) which assembles switch equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electric wiring requirement, and the arrangement of the electric control cabinet meets the requirement of normal operation of an electric power system, is convenient to overhaul and does not endanger the safety of people and surrounding equipment. Comprises a power distribution cabinet, a distribution box, an electric appliance control cabinet and the like. In some embodiments of the present application, the cabinet 10 may be a variable frequency electric control cabinet. The frequency conversion electric control cabinet is used for adjusting the working frequency of equipment, reducing energy loss, stably starting the equipment and reducing the damage of large current generated when the equipment is directly started to a motor. For convenience of description, the following embodiments all use the cabinet 10 as a frequency conversion electric control cabinet as an example for illustration.

In some embodiments, as shown in fig. 1, the cabinet 10 is provided with an electronic device 11 inside, and the electronic device 11 is connected with the controller 50. The electronic device 11 may be a frequency converter, which is an electric control device that applies a frequency conversion technology and a microelectronic technology to control an ac motor by changing a frequency mode of a working power supply of the motor. The frequency converter mainly comprises a rectifying unit (converting alternating current into direct current), a filtering unit, an inverting unit (converting direct current into alternating current), a braking unit, a driving unit, a detecting unit micro-processing unit and the like. The frequency converter adjusts the voltage and frequency of an output power supply by switching on and off of an internal IGBT, provides the required power supply voltage according to the actual requirement of the motor, and further achieves the purposes of energy saving and speed regulation. For convenience of description, the following embodiments are exemplified by taking the electronic device 11 as a frequency converter.

In some embodiments, as shown in fig. 1, a cold plate 12 is in contact with the electronic device 11, and a channel is formed inside the cold plate 12 for receiving a cooling medium and allowing the cooling medium to flow through the channel. Because the cold plate 12 has good thermal conductivity, when the temperature of the electronic device 11 is higher than the temperature of the refrigerant in the cold plate 12, the cold plate 12 directly contacts the electronic device 11, so that the heat of the electronic device 11 can be transferred into the refrigerant in the cold plate 12 to cool the electronic device 11. The cold plate 12 may be made of copper or aluminum, or any other metal product with good thermal conductivity.

In some embodiments, the compressor 13 is connected to the controller 50. As shown in fig. 1, a first inlet of the compressor 13 is communicated with an outlet of the evaporator 20, a first outlet of the compressor 13 is communicated with an inlet of the condenser 14, and a second inlet of the compressor 13 is communicated with a second outlet of the flash evaporator 19 through an outlet pipeline 21 of the flash evaporator 19.

In some embodiments, the condenser 14 is connected to a controller 50, as shown in fig. 1, and the outlet of the condenser 14 is connected to the second inlet of the flash evaporator 19 through a pipe and is connected to the channel of the cold plate 12 through the liquid guiding pipe 22.

In some embodiments, the flash evaporator 19 and the evaporator 20 are respectively connected to the controller 50, as shown in fig. 1, a first inlet of the flash evaporator 19 is communicated with the channel of the cold plate 12 through the outlet pipe 23 and the main outlet pipe 24, and a first outlet of the flash evaporator 19 is communicated with an inlet of the evaporator 20.

Thus, since the channel of the cold plate 12 is communicated with the outlet of the condenser 14 on one hand and the first inlet of the flash evaporator 19 on the other hand, the refrigerant in the channel of the cold plate 12 is always in the medium temperature and medium pressure state, that is, the temperature value of the refrigerant is not too low or too high, thereby preventing the electronic device 11 from being burnt due to overtemperature as much as possible and preventing the cold plate 12 from dewing due to too low temperature value as much as possible.

In some embodiments, the cooling system 1 further comprises a first throttle 17. As shown in fig. 2, another cooling system provided by the present application according to an exemplary embodiment may be provided with a throttle member 17 on a pipe connected between an outlet of the condenser 14 and the passage of the cold plate 12.

In some embodiments, the first throttling member 17 is connected to the controller 50, and the first throttling member 17 is used for regulating the flow of the refrigerant entering the channels of the cold plate 12.

In some embodiments, the first throttling element 17 may be an electronic device, such as an electronic expansion valve, or a mechanical device, such as a thermostatic expansion valve, a capillary tube, or the like.

In some embodiments of the present application, in order to improve the accuracy of the flow control of the refrigerant entering the passage of the cold plate 12, the first throttling element 17 is taken as an electronic expansion valve in the embodiments of the present application as an example for description.

Therefore, by arranging the first throttling element 17 on the pipeline connected between the outlet of the condenser 14 and the channel of the cold plate 12, the flow of the refrigerant entering the channel of the cold plate 12 is accurately controlled, the temperature value of the cold plate and the temperature value of the electronic device contacted with the cold plate are accurately controlled, and the probability of electric short circuit faults of the electronic device in the electric control cabinet due to condensation of the cold plate is reduced as far as possible.

In some embodiments, the cooling system 1 further comprises a first filter 15. As shown in fig. 3, another schematic composition diagram of a cooling system provided by the present application according to an exemplary embodiment, a first filter 15 may be disposed on a pipeline between the first throttling element 17 and the condenser 14, and the first filter is used for filtering the refrigerant entering the first throttling element 17.

It can be understood that, in the operation process of the refrigerating system 1, because the flow area of the throttling element is very small, if the impurities in the refrigerant are too much, the throttling element is easy to block, and then the accurate control of the refrigerant flow entering the throttling element cannot be realized. Like this, through set up first filter 15 on the pipeline between first throttling element 17 and condenser 14 to filter the impurity that gets into in the refrigerant of first throttling element 17, help promoting the precision to the control of the refrigerant flow of getting into first throttling element 17, also help promoting the precision to the temperature value control of cold plate 12, can reduce the probability that electronic device produces the electrical short circuit trouble because of the cold plate dewfall in rack 10.

In some embodiments, the cooling system 1 further comprises a first passage. Another schematic illustration of the composition of a cooling system provided according to an exemplary embodiment of the present application is shown in fig. 4. As shown in fig. 4, a first end of the first passage is communicated with the outlet of the condenser 14, a second end of the first passage is communicated with the first inlet of the flash evaporator, the first passage is at least partially located inside the cabinet 10, and the first passage is used for reducing the temperature value of the air in the cabinet 10, that is, cooling other electronic devices, such as a reactor cabinet, in the cabinet 10.

Continuing with fig. 4, the first path may consist of the pilot tube 22, the pilot tube 37, the outlet tube 27 and the main outlet tube 24.

In some embodiments, the cooling system 1 further comprises an air-cooled heat exchanger 25 and a fan 26. Referring to fig. 5, another schematic composition diagram of a cooling system provided by the present application according to an exemplary embodiment is shown, in which an air-cooled heat exchanger 25 is disposed on a first path, a first end of the air-cooled heat exchanger 25 may be communicated with an outlet of a condenser 14 through a liquid guiding pipe 37 and a liquid guiding pipe 22, and a second end of the air-cooled heat exchanger 25 may be communicated with a first inlet of a flash evaporator 19 through an air outlet pipe 27 and a main air outlet pipe 24.

The air-cooled heat exchanger 25 may be a finned tube heat exchanger or a microchannel heat exchanger.

In some embodiments, the cooling medium in the air-cooled heat exchanger 25 exchanges heat with the air in the cabinet 10 through the air flowing circulation formed by the fan 26, so as to reduce the temperature value of the air in the cabinet 10.

In some embodiments, the fan 26 is disposed inside the cabinet 10 and faces the air-cooled heat exchanger 25.

In some embodiments, the cooling system 1 further comprises a second throttle 29. As shown in fig. 6, which is a schematic composition diagram of another cooling system provided by the present application according to an exemplary embodiment, a second throttling element is disposed on the first passage and between the first end of the air-cooled heat exchanger 25 and the outlet of the condenser 14.

The second throttling element 29 is connected to the controller 50, and the second throttling element 29 is used for adjusting the flow rate of the refrigerant entering the air-cooled heat exchanger 25.

The second throttle 29 may be an electronic device, such as an electronic expansion valve, or a mechanical device, such as a thermostatic expansion valve, a capillary tube, or the like.

In some embodiments of the present application, in order to improve the accuracy of controlling the flow rate of the refrigerant entering the air-cooled heat exchanger 25, the second throttling element 29 is taken as an electronic expansion valve in the embodiments of the present application as an example for description.

So, set up second throttling element 29 on the pipeline that the export of condenser 14 is connected with air-cooled heat exchanger 25, the coolant flow that accurate control got into in the air-cooled heat exchanger 25, also realize the accurate control to the temperature value of air in rack 10 promptly, avoid not generating heat parts in the rack 10 because of the temperature value of air in rack 10 is low excessively and the dewfall, reduced the probability that other electronic device produced electric short circuit trouble in the rack 10.

In some embodiments, the cooling system 1 further comprises a second filter 28. As shown in fig. 7, another schematic composition diagram of a cooling system provided by the present application according to an exemplary embodiment, a second filter 28 may be disposed on a pipeline between the second throttling element 29 and the outlet of the condenser 14, and the second filter 28 is used for filtering the refrigerant entering the second throttling element 29.

Thus, the second filter 28 is arranged on the pipeline between the second throttling element 29 and the outlet of the condenser 14 to filter impurities in the refrigerant entering the second throttling element 29, so that the accuracy of controlling the flow rate of the refrigerant entering the second throttling element 29 is improved, the accuracy of controlling the temperature value of the air in the cabinet 10 is improved, and the probability of electric short circuit faults of other electronic devices caused by over-low condensation of the temperature value of the air in the cabinet 10 of the non-heat-generating device in the cabinet 10 can be reduced.

In some embodiments, as shown in fig. 7, since the first end of the air-cooled heat exchanger 25 is communicated with the outlet of the condenser 14, the second end of the air-cooled heat exchanger 25 is communicated with the first inlet of the flash evaporator 19, the refrigerant can pass through the liquid guiding pipe 22, the liquid guiding pipe 37 and the second filter 28 from the outlet of the condenser 14, and the filtered high-temperature and high-pressure liquid refrigerant without impurities is guided into the second throttling element 29, and since the air outlet pipe 27 of the air-cooled heat exchanger 25 is connected to the air outlet pipeline 21 of the flash evaporator 19 at the intermediate temperature and the intermediate pressure through the main air outlet pipe 24, the pressure and the temperature of the liquid refrigerant throttled by the second throttling element 29 are reduced, and the intermediate temperature and intermediate pressure gas-liquid two-phase refrigerant is formed and enters the air-cooled heat exchanger 25. Air within the cabinet 10 is circulated by the fan 26. In the air-cooled heat exchanger 25, after the liquid refrigerant exchanges heat with the circulating air, the liquid refrigerant evaporates to absorb heat, and the liquid refrigerant is changed into a gaseous refrigerant and enters the flash evaporator 19, and meanwhile, cold air with a lower temperature is generated at the air side and is blown into the cabinet 10, so that the electric components in the cabinet 10, such as a reactor, can not be overheated, and the air in the cabinet 10 can not be overheated, that is, the electronic components in the cabinet 10 can be effectively cooled.

It should be understood that, since the second end of the air-cooled heat exchanger 25 is communicated with the flash evaporator 19 through the air outlet pipe 27 and the main air outlet pipe 24, the refrigerant entering the air-cooled heat exchanger 25 is always in the medium-temperature and medium-pressure state, so that the temperature of the cool air blown out by the air-cooled heat exchanger 25 is not too low, and when the cool air is blown onto some non-heating components (such as a bracket) in the cabinet 10, the surface temperature of the components is not too low to generate dewing and dripping, thereby reducing the probability of electrical short circuit fault of the electronic devices in the cabinet 10.

In addition, when the air temperature and the air humidity in the cabinet 10 are high, the air-cooled heat exchanger 25 has the functions of cooling and dehumidifying, so that the air temperature and the air humidity in the cabinet 10 can be reduced, and dew condensation of all components including electronic devices, cold plates thereof and non-heat-generating components in the cabinet 10 is avoided. Even if the cabinet 10 is not tightly sealed from the outside high-humidity environment air, dew condensation does not occur.

In some embodiments, the cooling system 1 further comprises a third throttle 16. As shown in fig. 8, another composition diagram of a cooling system provided by the present application according to an exemplary embodiment, a third throttling element 16 may be disposed between the outlet of the condenser 14 and the second inlet of the flash evaporator 19, and the third throttling element 16 is used for regulating the flow rate of the refrigerant entering the flash evaporator 16.

In some embodiments, the third throttling element 16 may be an electronic device, such as an electronic expansion valve. Mechanical devices such as thermal expansion valves, capillary tubes, etc. are also possible, without limitation.

In some embodiments, the cooling system 1 further comprises a fourth throttle 18.

In some embodiments, the fourth restriction 18 may be an electronic device, such as an electronic expansion valve. Mechanical devices such as thermal expansion valves, capillary tubes, etc. are also possible, without limitation.

The following illustrates a refrigeration process according to an embodiment of the present application: in the application, the refrigeration system executes the refrigeration cycle of the cooling system by using the compressor, the condenser, the expansion valve, the evaporator and the flash evaporator as a refrigerant circulation loop. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant (e.g., refrigerant) to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The flash evaporator converts the low-pressure liquid-phase refrigerant into a medium-temperature medium-pressure liquid-gas two-phase refrigerant. The evaporator evaporates the refrigerant expanded in the electronic expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. Throughout the cycle, the cooling system may regulate the temperature of the air within the cabinet and the temperature of the electronics within the cabinet.
