Description

Technical Field

[0001] The utility model belongs to the technical field of liquid storage tanks for refrigeration equipment, and particularly relates to a liquid storage tank for an integrated system of active and passive heat conduction. Background Art

[0002] The operation of an air-conditioning compressor can be divided into four steps: adiabatic compression, condensation, throttling, and evaporation. In the adiabatic compression stage, electrical energy does mechanical work, and the refrigerant is compressed in the compressor. At this time, the temperature of the refrigerant rises and the pressure increases. Then, the high-temperature and high-pressure gaseous refrigerant enters the condenser to release heat and undergoes a gas-liquid phase change to become a high-pressure liquid refrigerant. Next, after throttling through an expansion valve or a throttle valve, the refrigerant becomes a low-pressure and low-temperature liquid or a gas-liquid two-phase state. Finally, the refrigerant enters the evaporator to absorb heat and evaporate, thereby cooling the surrounding air or water. This process is a non-spontaneous refrigeration cycle, which causes heat to transfer from a low-temperature object to a high-temperature object. Generally speaking, when the air-conditioning compressor operates, it continuously absorbs the heat at the low-pressure end into the refrigerant and then sends it to the high-pressure area to be distributed into the air, continuously playing the role of regulating the temperature.

[0003] Currently, the number of base stations, cabinets, and shelters is increasing year by year, and a large number of heat-generating devices need to be cooled throughout the year. If relying solely on the air-conditioning system for cooling, the air-conditioning compressor needs to operate for a long time, resulting in high energy consumption. At present, in order to achieve energy conservation and emission reduction of the air-conditioning system, in addition to improving the energy efficiency ratio of the air-conditioning system itself, it is to reduce the operation time of the air-conditioning compressor and make the best use of natural cold sources as much as possible. Thus, a refrigeration system combining the air-conditioning mode and the heat pipe mode appears. However, the liquid filling rate of the air-conditioning system when working in the heat pipe system mode is significantly different from that when working in the compressor mode. The existing liquid storage device is connected in series in the entire refrigeration pipeline and becomes a part of the refrigeration pipeline. When the mode is switched, it is relatively passive in adding working medium to the pipeline or storing redundant working medium, with low efficiency. This is because the liquid storage device, as a part of the main pipeline of the pipeline, its performance often becomes the bottleneck of the entire pipeline, increasing the difficulty of controlling the integrated system. For example, when switching from the air-conditioning mode to the heat pipe mode, the injection rate of the working medium in the main pipeline of the pipeline is low, and the working medium in the liquid storage device is difficult to be added to the main pipeline in time. At this time, the performance of the heat pipe is poor, or even it cannot be started, resulting in a shortened service time of the heat pipe and a significant decline in the overall economic performance of the system. Summary of the Utility Model

[0004] In view of the above situation, to overcome the defects of the prior art, the utility model provides a liquid storage tank for an active and passive heat conduction integrated system. The liquid storage tank for the active and passive heat conduction integrated system can accurately adjust the working medium pressure at the outlet of the condenser, adjust the working medium pressure in this section to the best state, and then control the pressure characteristics in the entire main pipeline, so that the working medium quantity in the integrated system is in the best state in the air-conditioning mode and the heat pipe mode and better matches the corresponding modes, greatly improving the refrigeration effect of the refrigeration system in the two modes.

A control pipeline assembly for the circulation of the refrigerant working medium is arranged on the side of the sealing structure far from the liquid storage air bag. An exhaust assembly for discharging the gas in the liquid storage air bag is arranged at the center of the sealing structure. A monitoring assembly for real-time monitoring of the working medium state in the liquid storage air bag and the tank body is arranged on one side of the sealing structure close to the liquid storage air bag and the top of the side of the tank body. An air pump for pressurizing the inside of the tank body is fixedly installed at the top end of the tank body.

[0006] Preferably, the sealing structure includes a sealing gasket and a sealing cover. The sealing cover is fixedly connected to the bottom of the tank body by bolts, and the sealing gasket is clamped between the tank body and the sealing cover.

[0007] Preferably, the liquid storage air bag is fixedly connected to one side of the sealing cover close to the inside of the tank body, and the liquid storage air bag is arranged inside the tank body and below the arc-shaped partition.

[0008] Preferably, the control pipeline assembly includes a liquid inlet pipe, a liquid outlet pipe, a first one-way solenoid valve, and a second one-way solenoid valve. The liquid inlet pipe and the liquid outlet pipe are both fixedly connected to the side of the sealing cover far from the tank body and are both communicated with the inside of the liquid storage air bag. The liquid inlet pipe and the liquid outlet pipe are symmetrically arranged with the vertical center line of the sealing cover as the axis of symmetry.

[0009] Preferably, the first one-way solenoid valve and the second one-way solenoid valve are respectively fixedly installed at the bottom of the sides of the liquid inlet pipe and the liquid outlet pipe.

[0010] Preferably, the exhaust structure includes an exhaust pipe, a protective head, and a third one-way solenoid valve. The exhaust pipe is fixedly installed at the center of the sealing cover and penetrates through the inside of the liquid storage air bag. The protective head is fixedly connected to the top of the exhaust pipe and is arranged inside the liquid storage air bag.

[0011] Preferably, exhaust holes for discharging the gas in the liquid storage airbag are formed around the top of the exhaust pipe, and the third one-way solenoid valve is fixedly installed at one end of the exhaust pipe close to the control pipeline assembly.

[0013] Preferably, the monitoring assembly includes a liquid level gauge, a temperature sensor, a liquid pressure sensor and a gas pressure sensor. The liquid level gauge is fixedly installed on one side of the sealing cover close to the liquid storage airbag and is vertically arranged inside the liquid storage airbag.

When the air conditioner compressor operates, the high-pressure working medium coming out of the condenser can enter the liquid storage airbag in the liquid storage tank through the control pipeline assembly. After filling a predetermined amount, the control pipeline assembly is closed. When switching to the heat pipe, the pressure of the main pipeline will become lower. At this time, the control pipeline assembly is opened to release the high-pressure working medium in the liquid storage airbag, so as to accurately adjust the pressure of the working medium at the outlet of the condenser, adjust the pressure of the working medium in this section to the best state, and further control the pressure characteristics in the whole main pipeline, so that the amount of the working medium in the integrated system is in the best state in the air conditioner mode and the heat pipe mode and better matches the corresponding modes, greatly improving the refrigeration effect of the refrigeration system in the two modes.

[0017] (2) The liquid storage tank for the integrated active and passive heat conduction system can easily discharge the excess gas in the liquid storage airbag through the exhaust assembly, enabling the refrigerant working medium in the main pipeline to smoothly enter the liquid storage airbag, avoiding the influence on the storage of the refrigerant working medium due to excessive gas in the liquid storage airbag. Moreover, the liquid storage tank is not connected in series to the main pipeline. It exists as a branch and does not participate in the heat pipe mode and the compressor mode of the air conditioner. It is only used for storing or replenishing the working medium. Therefore, neither the replacement of the liquid storage tank nor the internal structure of the liquid storage tank will become a factor affecting the operation of the main pipeline. At the same time, a new adjustment method is adopted to adjust the pressure of the main pipeline by regulating the pressure of the liquid storage branch. There is no need to transform the main pipeline, and only the structure of the liquid storage branch needs to be adjusted, which is convenient for installation and maintenance.

DETAILED DESCRIPTION OF THE EMBODIMENT

[0023] Regarding the foregoing and other technical contents, features and effects of the present utility model, the following will be described in detail in conjunction with the Figures 1 to 4 embodiments for reference.

[0024] This embodiment provides a liquid storage tank for an integrated active and passive heat conduction system, as shown in the attached Figures 1 - 4As shown in the figure, it includes a tank body 1 and a thermal insulation layer 2. The thermal insulation layer 2 is bonded to the outside of the tank body 1, which can play a good role in thermal insulation for the inside of the tank body 1, ensuring that the refrigerant working medium stored inside can remain in a low-temperature state for a long time. At the top end inside the tank body 1, an arc-shaped partition 3 is fixedly connected, and air holes 4 are provided on the surface of the arc-shaped partition 3. The bottom of the tank body 1 is bolted with a sealing structure for ensuring the overall sealing of the tank body 1. The sealing structure includes a sealing gasket 7 and a sealing cover 8. The sealing cover 8 is fixedly connected to the bottom of the tank body 1 by bolts, and the sealing gasket 7 is clamped between the tank body 1 and the sealing cover 8. The sealing gasket 7 can ensure the sealing inside the tank body 1 and prevent the working medium inside from leaking. On the side of the sealing structure close to the inside of the tank body 1, a liquid storage airbag 5 for storing the refrigerant working medium is fixedly connected. The liquid storage airbag 5 is fixedly connected to the side of the sealing cover 8 close to the inside of the tank body 1 and is arranged inside the tank body 1. The liquid storage airbag 5 is an expandable rubber airbag. When storing high-pressure liquid working medium inside it, it will expand to abut against the arc-shaped partition 3 and the inner surface of the tank body 1. The arc-shaped partition 3 can play a role in limiting the liquid storage airbag 5, ensuring that the top inside the tank body 1 is an air cavity for storing gas, and the inside of the liquid storage airbag 5 is a liquid cavity for storing liquid refrigerant working medium. The liquid storage airbag 5 makes the gas and liquid working medium not in contact with each other, which can ensure that the liquid working medium is not polluted by the gas and prevent the liquid working medium from evaporating and overflowing;

[0025] On the side of the sealing structure far from the liquid storage airbag 5, a control pipeline assembly for the circulation of the refrigerant working medium is provided. The control pipeline assembly includes an inlet pipe 9, an outlet pipe 10, a first one-way solenoid valve 11, and a second one-way solenoid valve 12. Both the inlet pipe 9 and the outlet pipe 10 are fixedly connected to the side of the sealing cover 8 far from the tank body 1 and are both communicated with the inside of the liquid storage airbag 5. The inlet pipe 9 and the outlet pipe 10 are symmetrically arranged with the vertical midline of the sealing cover 8 as the axis of symmetry. The first one-way solenoid valve 11 and the second one-way solenoid valve 12 are respectively fixedly installed on the sides of the inlet pipe 9 and the outlet pipe 10. The bottom ends of the inlet pipe 9 and the outlet pipe 10 are at the same horizontal plane and are both bolted in parallel to the main pipeline at the outlet of the condenser and are communicated with the inside of the main pipeline. The first one-way solenoid valve 11 is an inlet one-way valve. When it is opened, it can only allow the working medium in the main pipeline to enter the liquid storage airbag 5 from the inlet pipe 9 without generating backflow. The second one-way solenoid valve 12 is an outlet one-way valve. When it is opened, it can only allow the working medium in the liquid storage airbag 5 to be discharged into the main pipeline from the outlet pipe 10 without generating backflow;

[0026] The first one-way solenoid valve 11, the second one-way solenoid valve 12, the third one-way solenoid valve 15, the liquid level gauge 17, the temperature sensor 18, the liquid pressure sensor 19, and the air pressure sensor 20 are all electrically connected to an external control unit. When the integrated refrigeration system needs to perform active heat dissipation, the compressor operates. Since less refrigerant working medium is required in the compressor operation mode, the excess refrigerant working medium needs to be discharged from the main pipeline. At this time, the control unit opens the first one-way solenoid valve 11 in the liquid inlet pipe 9. Since the pressure in the tank 1 is less than the pressure in the main pipeline, the high-pressure refrigerant working medium at the outlet of the condenser will enter the liquid storage airbag 5 in the tank 1 from the liquid inlet pipe 9. Then, it is adjusted according to the real-time monitoring situation in the integrated refrigeration system. When it is detected that the amount of working medium in the main pipeline is suitable for the compressor operation mode, the first one-way solenoid valve 11 is closed. At this time, the liquid storage tank as a branch no longer works, does not participate in the refrigeration cycle, and is independent of the main pipeline. It can not only ensure that the refrigerant working medium inside the main pipeline of the compressor during active operation is in a suitable state, but also collect the excess refrigerant working medium for use during the passive heat dissipation of the integrated refrigeration system;

[0027] An exhaust component for discharging the gas in the liquid storage airbag 5 is provided at the center of the sealing structure. The exhaust structure includes an exhaust pipe 13, a protective head 14, and a third one-way solenoid valve 15. The exhaust pipe 13 is fixedly installed at the center of the sealing cover 8 and penetrates inside the liquid storage airbag 5. The protective head 14 is fixedly connected to the top of the exhaust pipe 13, and exhaust holes 16 are provided around the top of the exhaust pipe 13. The design of the protective head 14 can ensure the smoothness of the top of the exhaust pipe 13 and will not affect the flow of the exhaust pipe 13 when the liquid storage airbag 5 contracts inward. The third one-way solenoid valve 15 is fixedly installed at one end of the exhaust pipe 13 close to the control pipeline assembly. The third one-way solenoid valve 15 is an air outlet one-way valve. When it is opened, only the gas in the liquid storage airbag 5 can be discharged into the main pipeline and no backflow will occur. The exhaust pipe 13 is arranged between the liquid inlet pipe 9 and the liquid outlet pipe 10, and the bottom end is at the same horizontal plane as the bottom ends of the liquid inlet pipe 9 and the liquid outlet pipe 10. Since the refrigerant working medium will carry gas when entering the liquid storage airbag 5 from the main pipeline, the third one-way solenoid valve 15 can be opened separately without opening the liquid outlet pipe 10. The gas entering the liquid storage airbag 5 can enter the exhaust holes 16 and be discharged back into the main pipeline through the exhaust pipe 13;

[0028] On one side of the sealing structure close to the liquid storage airbag 5 and at the top of the side of the tank body 1, a monitoring component for real-time monitoring of the working medium state in the liquid storage airbag 5 and the tank body 1 is provided. The monitoring component includes a liquid level gauge 17, a temperature sensor 18, a liquid pressure sensor 19, and a gas pressure sensor 20. The liquid level gauge 17 is fixedly installed on one side of the sealing cover 8 close to the liquid storage airbag 5 and is vertically arranged inside the liquid storage airbag 5. The temperature sensor 18 and the liquid pressure sensor 19 are both fixedly installed on one side of the sealing cover 8 close to the inside of the liquid storage airbag 5. The gas pressure sensor 20 is fixedly installed at the top of the side of the tank body 1, and its detection end is arranged between the arc-shaped partition plate 3 and the inner top wall of the tank body 1. The liquid level gauge 17 can real-time monitor the liquid level height of the liquid refrigerant working medium in the liquid storage airbag 5, and the liquid pressure sensor 19 can real-time detect the pressure of the liquid working medium in the liquid storage airbag 5. The two cooperate with each other to know the content of the working medium in the liquid storage airbag 5, which is convenient for dynamic regulation. The temperature sensor 18 can real-time detect the temperature of the liquid working medium in the liquid storage airbag 5, and the gas pressure sensor 20 can detect the air pressure in the air cavity part of the tank body 1. An air pump 6 for pressurizing its interior is fixedly installed at the top end of the tank body 1. The air pump 6 is fixedly installed at the central part of the top of the tank body 1, and the inflation end of the air pump 6 penetrates into the interior of the tank body 1. When it is necessary to discharge the liquid working medium in the liquid storage airbag 5 into the main pipeline, on the one hand, the working medium in the liquid storage airbag 5 can be automatically discharged into the main pipeline by using the principle of pressure difference. On the other hand, when the pressure in the liquid storage airbag 5 is not much different from the pressure in the main pipeline, the air pump 6 can be used to inflate the air cavity in the tank body 1 to form a high pressure, thereby compressing the liquid storage airbag 5 to contract, and discharging the liquid working medium inside it from the liquid outlet pipe 10 into the main pipeline.

[0029] In summary, the steps for using the liquid storage tank for the integrated active and passive heat conduction system are as follows:

[0030] 1. When performing active heat conduction, the air-conditioning compressor operates, and the control unit opens the first one-way solenoid valve 11 in the liquid inlet pipe 9. Since the pressure in the tank body 1 is less than the pressure in the main pipeline, the high-pressure refrigerant working medium at the outlet of the condenser will enter the liquid storage airbag 5 in the tank body 1 from the liquid inlet pipe 9. Subsequently, the high-pressure liquid working medium enters the liquid storage airbag 5, and the pressure in the liquid storage airbag 5 gradually approaches the pressure in the main pipeline. The gas entering the liquid storage airbag 5 is stored at the top of the liquid storage airbag 5. When there is too much gas, the third one-way solenoid valve 15 can be opened, and the gas in the liquid storage airbag 5 will be squeezed into the main pipeline through the exhaust pipe 13 to ensure that the liquid storage airbag 5 can collect enough refrigerant working medium.

[0031] 2. When it is detected that the working medium content in the main pipeline is suitable for the compressor operation mode, the first one-way solenoid valve 11 is closed. The refrigerant working medium content in the main pipeline is suitable for the current active heat conduction mode, and the excess refrigerant working medium is stored in the liquid storage airbag 5 in the tank body 1.

[0032] 3. When the passive heat dissipation mode needs to be adopted, the air conditioner compressor is turned off, and at the same time, the second one-way solenoid valve 12 on the liquid outlet pipe 10 is opened. The liquid refrigerant working medium in the high-pressure state in the liquid storage airbag 5 will be discharged from the liquid outlet pipe 10 into the main pipeline under the action of the pressure difference. The flow rate of the working medium is controlled by the throttle valve on the main pipeline, so that the content of the refrigerant working medium inside the main pipeline remains within a suitable range during passive heat dissipation. After reaching the suitable range, the second one-way solenoid valve 12 is closed, and the liquid storage tank is re-isolated from the integrated refrigeration system.

[0033] The above description is only for the purpose of illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various equivalent forms that conform to the idea of the present invention are within the protection scope of the present invention.
