Description

Technical Field

[0001] The embodiments of the present application relate to the field of heat exchange technology, and in particular to a gas-liquid separator, a heat exchange system and communication equipment. Background Art

[0002] Two-phase liquid cooling technology is a key technology to solve the heat dissipation of high-power consumption and high-heat flux density electronic devices (such as chips). It is used to ensure the operating temperature of electronic devices, and thus ensure the working performance of electronic devices.

[0003] The heat exchange system using two-phase liquid cooling technology includes an evaporator, a condenser and a gas-liquid separator. The gas-liquid separator is arranged between the condenser and the evaporator to contain and release the heat exchange medium flowing out of the condenser to maintain the stable operation of the system. In the related art, the adjustability of the gas-liquid separator is poor, which is not conducive to ensuring the safe and stable operation of the system when the operating conditions of the system fluctuate.

[0004] Therefore, how to provide a solution to improve the adjustability of the gas-liquid separator is still a technical problem that needs to be urgently solved by those skilled in the art. Summary of the invention

[0005] The embodiments of the present application provide a gas-liquid separator, a heat exchange system and communication equipment, wherein the gas-liquid separator has better adjustability, which is conducive to ensuring the safe and stable operation of the heat exchange system.

[0006] In the first aspect, an embodiment of the present application provides a gas-liquid separator, which is applied to a heat exchange system, and is specifically arranged between the condenser and the evaporator of the heat exchange system, so as to perform gas-liquid separation on the heat exchange medium discharged from the condenser. The gas-liquid separator includes a shell, a partition component and an active actuator component. The shell is the external structure of the gas-liquid separator, and the shell is provided with an inlet portion and an outlet portion. A working chamber is provided inside the shell, and the inlet portion and the outlet portion are both connected to the working chamber, so as to introduce and export the heat exchange medium into and out of the working chamber. The partition component is arranged in the shell, and the active actuator component is used to adjust the use state of the partition component to adjust the volume of the working chamber.

[0007] In the above scheme, the active execution component can adjust the use state of the partition component, and then adjust the volume of the working chamber, which can increase the adjustability of the gas-liquid separator provided in the example of the present application, and thus better adapt to the operating condition fluctuations of the heat exchange system.

[0008] Specifically, when the volume of the working chamber increases, more space can be provided for the gas phase in the heat exchange medium, which is beneficial to maintaining the pressure stability inside the system; when the volume of the working chamber decreases, the liquid level of the liquid phase in the heat exchange medium can be increased, and the liquid level in the first chamber can be maintained, which can largely avoid the flow of liquid-free heat exchange medium into downstream equipment and cause damage to the downstream equipment.

[0009] For a pumpless heat exchange system, the downstream equipment mainly refers to the evaporator. The above solution can reduce the situation where the heat exchange medium in the evaporator is evaporated, which is conducive to ensuring the safe and stable operation of the evaporator. For a pump-driven heat exchange system, the downstream equipment refers to the pump body. The above solution can largely avoid the impact of the gas-phase heat exchange medium on the pump body, which is conducive to ensuring the safe operation of the pump-driven heat exchange system.

[0010] Based on the first aspect, the embodiment of the present application also provides a first implementation of the first aspect: the partition component and the inner wall of the shell enclose a first chamber. The inlet and the outlet are both directly connected to the first chamber, and the working chamber includes the first chamber. The use state of the partition component includes the position state of the partition component in the shell. Accordingly, the active actuator is used to drive the partition component to displace in the shell to adjust the position of the partition component, thereby directly adjusting the volume of the first chamber.

[0011] In this solution, the heat exchange medium only exists in the first chamber, and the first chamber is directly connected to the inlet and outlet. Under conditions such as equipment maintenance, the heat exchange medium can be easily and completely discharged from the first chamber, which can reduce the retention of the heat exchange medium in the gas-liquid separator.

[0012] Based on the first implementation of the first aspect, the embodiment of the present application also provides a second implementation of the first aspect: the active execution component includes a motor and a transmission part, the motor and the transmission part are connected in a transmission manner to drive the transmission part to move, and the transmission part is connected to the partition component.

[0013] The motor can realize its own opening and closing control only by powering on and off, without complicated gas circuit structure or liquid circuit structure, and the overall structure is simple. In addition, the motor has a self-locking function, which can better control the position of the partition component in the shell, so as to accurately control the volume of the working chamber.

[0014] The transmission part can be a rack, in which case the motor can be equipped with a gear, and the rotation of the gear can drive the rack to perform linear displacement, thereby driving the partition component to adjust its position. Alternatively, the transmission part can also be a lead screw, in which case the active actuator can also include a lead screw nut, the motor can drive the lead screw nut to rotate, and the lead screw can mesh with the lead screw nut to perform linear displacement driven by the lead screw nut.

[0015] It should be understood that, in addition to the motor solution, the active execution component may also adopt a hydraulic drive component or a pneumatic drive component, etc., which can also realize the drive of the partition component.

[0016] Based on the second implementation of the first aspect, the embodiment of the present application also provides a third implementation of the first aspect: the motor is arranged on the outside of the shell to reduce the occupancy of the internal space of the shell, which is conducive to reducing the total volume of the shell, and then reducing wind resistance to improve the heat exchange performance of the heat exchange system in a limited space, and can also increase the movable range of the partition component, which is conducive to increasing the adjustable range of the volume of the first chamber.

[0017] Based on the first implementation of the first aspect, the embodiment of the present application also provides a fourth implementation of the first aspect: the active actuator is a magnetic drive unit, and the magnetic drive unit is used to drive the partition component to move. In this way, there is no need to configure a mechanical transmission structure between the active actuator and the partition component, which is conducive to the simplification of the structure of the gas-liquid separator. At the same time, it can also reduce the occupation of the internal space of the shell, so that more space inside the shell can be used as a working chamber, which is also conducive to increasing the adjustable range of the volume of the working chamber.

[0018] Based on the first aspect, or based on any one of the first to fourth embodiments of the first aspect, the embodiment of the present application also provides a fifth embodiment of the first aspect: the partition component is used to divide the interior of the shell into a first chamber and a second chamber, and the inlet and the outlet are directly connected to the first chamber; the use state includes the connectivity state of the partition component, and the connectivity state includes a connected state and an isolated state; in the connected state, the first chamber and the second chamber are connected, the working chamber includes the first chamber and the second chamber, and the volume of the working chamber is expanded; in the isolated state, the first chamber and the second chamber are isolated, the working chamber includes the first chamber, and the volume of the working chamber is locked; the active actuator is used to drive the partition component to switch between the connected state and the isolated state.

[0019] Based on the fifth implementation of the first aspect, the embodiment of the present application further provides a sixth implementation of the first aspect: the partition component is provided with a communication port, the active execution component includes a switch valve provided in the communication port, and the switch valve is used to control the opening and closing of the communication port. When the switch valve is in an open state, the first chamber and the second chamber can be connected, and the volume of the working chamber can be expanded; when the switch valve is in a closed state, the first chamber and the second chamber can be isolated, and the volume of the working chamber can be reduced.

[0020] Based on the sixth implementation of the first aspect, the embodiment of the present application also provides a seventh implementation of the first aspect: the first chamber includes an air cavity and a liquid cavity, and at least one of the air cavity and the liquid cavity can be connected to the second chamber through a connecting port.

[0021] When the switch valve is in the open state, the partition component is in the connected state, and the air cavity and the second chamber can be connected. At this time, the space for accommodating the gas phase heat exchange medium is expanded, which is conducive to the pressure drop inside the heat exchange system and can better cope with the working condition of excessive pressure in the heat exchange system. When the switch valve is in the closed state, the partition component is in the isolated state, and the first chamber and the second chamber can be isolated.

[0022] Based on the first aspect, or based on any one of the first to seventh embodiments of the first aspect, the embodiment of the present application also provides an eighth embodiment of the first aspect: it also includes a monitoring component, which is arranged in the working chamber and is used to monitor the characteristic parameters in the working chamber. The active execution component is signal-connected to the monitoring component, and the active execution component is used to adjust the use status of the separation component according to the characteristic parameters to better adapt to the operating conditions of the system.

[0023] Based on the eighth implementation of the first aspect, the embodiment of the present application also provides a ninth implementation of the first aspect: the monitoring component includes at least one of a liquid level measuring device, a temperature measuring device, a pressure measuring device, and a humidity measuring device, and accordingly, the characteristic parameters may include liquid level height, temperature, pressure, and humidity, etc.

[0024] Based on the first aspect, or based on any one of the first to ninth embodiments of the first aspect, the embodiment of the present application also provides a tenth embodiment of the first aspect: it also includes a filtering component for filtering the heat exchange medium flowing into or out of the working chamber, and can filter out impurities that may be present in the heat exchange medium, thereby improving the cleanliness of the heat exchange medium.

[0025] Based on the tenth implementation of the first aspect, the embodiment of the present application also provides the eleventh implementation of the first aspect: the filter component is arranged in the working chamber, the filter component and the partition component are connected, and the partition component can adjust the filter area of ​​the filter component, thereby further increasing the adjustability of the gas-liquid separator provided in the embodiment of the present application.

[0026] Based on the eleventh embodiment of the first aspect, the embodiment of the present application also provides the twelfth embodiment of the first aspect: in the displacement direction of the partition component, at least a part of the filter component is a foldable and retractable part, one end of the filter component is fixedly connected to the inner wall surface of the working chamber, and the other end of the filter component is fixedly connected to the partition component; or, the filter component includes a first filter part and a second filter part that are slidably connected, the first filter part and the partition component are fixedly connected, and the second filter part and the inner wall surface of the working chamber are fixedly connected; or, the filter component includes a winding shaft and a retractable filter element, the filter element is wound on the winding shaft, and the filter element has an extension part, the extension part is fixedly connected to one of the partition component and the inner wall surface of the working chamber, and the winding shaft is fixedly connected to the other of the partition component and the inner wall surface of the working chamber.

[0027] By adjusting the filtering area of ​​the filtering component, the filtering performance of the filtering component and the resistance generated to the heat exchange medium are different, and the impact on the operation of the heat exchange system is also different, which can greatly improve the adjustability of the gas-liquid separator.

[0028] In the second aspect, an embodiment of the present application also provides a heat exchange system, including an evaporator, a condenser and a gas-liquid separator, wherein the gas-liquid separator is arranged between the condenser and the evaporator and downstream of the condenser, and the gas-liquid separator is any one of the gas-liquid separators involved in the first aspect or the various embodiments of the first aspect.

[0029] The gas-liquid separator configured for the above heat exchange system has better adjustability, can better adapt to the operating conditions of the heat exchange system, and is conducive to ensuring the stable and safe operation of the heat exchange system.

[0030] On the third aspect, the embodiments of the present application also provide a communication device, which can be specifically a base station, a server, etc., including a device body and the heat exchange system involved in the second aspect. The device body is provided with a temperature control device, and the temperature control device is installed on an evaporator. The evaporator can cool and dissipate the temperature control device to ensure the working temperature of the temperature control device.

[0031] Since the heat exchange system in the second aspect has high stability and safety, accordingly, when applied to communication equipment, it can better control the temperature of the temperature control device, and is also conducive to ensuring the safe and stable operation of the communication equipment.

[0054] Embodiment 1

[0055] Please refer to Figure 1 , Figure 1 This is a simplified structural diagram of the heat exchange system provided in an embodiment of the present application.

[0056] like Figure 1As shown, the embodiment of the present application provides a heat exchange system, specifically a heat exchange system using two-phase liquid cooling technology, which can be applied to conventional mechanical equipment such as industrial equipment and vehicles, and can also be applied to communication equipment such as computing equipment in the form of base stations and servers. Taking communication equipment as an example, the communication equipment may include a device body, and the device body may include a temperature control device 400. The temperature control device 400 may specifically be an electronic device in various forms such as a chip, a motherboard, a hard disk, and a memory. During use, the temperature control device 400 will generate a large amount of heat.

[0057] The heat exchange system includes an evaporator 100, a condenser 200 and a gas-liquid separator 300. The gas-liquid separator 300 is disposed between the condenser 200 and the evaporator 100 and is located downstream of the condenser 200. A heat exchange medium circulates in the heat exchange system, and the heat exchange medium may specifically be a fluorinated liquid, deionized water, etc. It should be understood that the "downstream" in the embodiment of the present application refers to the flow direction of the heat exchange medium in the heat exchange system (such as Figure 1 ), the gas-liquid separator 300 is located downstream of the condenser 200, that is, the heat exchange medium in the condenser 200 can flow to the gas-liquid separator 300.

[0058] The evaporator 100 is provided with an evaporation chamber (not shown in the figure), and the evaporation chamber contains a liquid phase heat exchange medium. The evaporator 100 can be installed on the temperature control device 400. In actual application, the temperature control device 400 generates heat, and the liquid phase heat exchange medium in the evaporation chamber can absorb the heat generated by the temperature control device 400 and undergo a phase change to form a gas phase heat exchange medium, thereby cooling and dissipating the temperature control device 400, so that the temperature control device 400 can work within a set temperature range, thereby ensuring the working performance of the temperature control device 400.

[0059] The heat exchange medium in the evaporator 100 can be passed into the condenser 200. This part of the heat exchange medium is mainly a gas phase heat exchange medium formed by phase change. Of course, it may also contain some liquid phase heat exchange medium. For the convenience of description, the heat exchange medium passed from the evaporator 100 to the condenser 200 can be called an evaporating medium. After entering the condenser 200, at least part of the gas phase heat exchange medium in the evaporating medium can be condensed and liquefied to form a liquid phase heat exchange medium by phase change.

[0060] Then, the heat exchange medium in the condenser 200 can be passed into the gas-liquid separator 300. This part of the heat exchange medium is mainly liquid-phase heat exchange medium. Of course, it may also contain some gas-phase heat exchange medium, which is related to the operating conditions of the heat exchange system. For the convenience of description, the heat exchange medium passed from the condenser 200 to the gas-liquid separator 300 is called condensing medium. After entering the gas-liquid separator 300, the condensing medium can be separated into gas and liquid, and the liquid-phase heat exchange medium can flow back to the evaporator 100 to complete the circulation of the heat exchange medium.

[0061] In some embodiments, the heat exchange system may also be configured with a pump body, which may be located between the gas-liquid separator 300 and the evaporator 100 to provide sufficient power for the circulation of the heat exchange medium; such a heat exchange system may also be referred to as a pump-driven heat exchange system. In other embodiments, the heat exchange system may not be configured with a pump body, in which case the installation positions of the condenser 200 and the gas-liquid separator 300 may be controlled, for example, the condenser 200 may be set at a position higher than the gas-liquid separator 300, and the gas-liquid separator 300 may be set at a position higher than the evaporator 100, so as to make full use of the gravity of the heat exchange medium itself to drive the heat exchange medium to flow from the condenser 200 to the gas-liquid separator 300, and then to the evaporator 100; such a heat exchange system may also be referred to as a pumpless heat exchange system.

[0062] It should be understood that the above heat exchange system can not only realize cooling and heat dissipation of the temperature control device 400, but also realize heating of the temperature control device 400. In this embodiment, the temperature control device 400 can be installed on the condenser 200 to heat up by condensation heat release of the evaporating working fluid entering the condenser 200. This is also feasible. For example, when the heat exchange system is applied to scenes such as automobiles, the battery and other components of the automobile often face the problem of being unable to start in seasons with relatively low temperatures such as winter. In this case, the heat released by the condenser 200 can be used to heat up the battery and other components to ensure the smooth start of the automobile.

[0063] In the heat exchange system, the gas-liquid separator 300 can contain and release the condensed working fluid flowing out of the condenser 200 to maintain the stable operation of the system. At the same time, for the embodiment with a pump body, the two-phase separation effect of the gas-liquid separator 300 can largely avoid the impact of the gas-phase heat exchange working fluid on the pump body, which is conducive to the maintenance of the pump body to maintain the safe operation of the system.

[0064] However, as described in the background technology section, in the related art, the gas-liquid separator has poor adjustability. Once the operating conditions of the heat exchange system fluctuate, it is difficult to ensure the stable and safe operation of the system. In view of this, the embodiment of the present application also provides a gas-liquid separator 300 with better adjustability, which can better cope with the fluctuation of the operating conditions of the heat exchange system. For details, please refer to the following embodiments 2 to 4.

[0065] Embodiment 2

[0066] Please refer to Figure 2-Figure 5 , Figure 2 This is a schematic structural diagram of the first embodiment of the gas-liquid separator provided in the embodiments of the present application. Figure 3 for Figure 2 A structural diagram of a variant of Figure 4 for Figure 2 A schematic diagram of another variant of the structure of Figure 5 for Figure 2 A schematic structural diagram of yet another variant of the present invention.

[0067] like Figure 2 As shown, in the embodiment of the present application, the gas-liquid separator 300 includes a shell 310 , a partition component 320 and an active execution component 330 .

[0068] The shell 310 is an external component of the gas-liquid separator 300, and can protect the various components inside the gas-liquid separator 300. The shell 310 also forms the outer contour of the gas-liquid separator 300 and basically determines the overall shape of the gas-liquid separator 300. In some embodiments, the shell 310 can be roughly presented in a relatively regular spatial shape such as a prism (number of prisms ≥ 3) or a cylinder to facilitate processing. In other embodiments, the shell 310 can also be presented in some irregular spatial shapes, such as a U-shape, etc., to avoid some components in the heat exchange system or in the specific application scenarios of the heat exchange system, which can better meet the requirements of use.

[0069] The shell 310 is also provided with an inlet 340 and an outlet 350. The inlet 340 can be connected to the condenser 200, and the outlet 350 can be connected to the evaporator 100. In this way, the condensed working medium flowing out of the condenser 200 can flow into the shell 310 through the inlet 340, and the liquid phase heat exchange working medium formed after gas-liquid separation can flow out of the shell 310 through the outlet 350. The inlet 340 and the outlet 350 can specifically be openings provided in the shell 310, or the inlet 340 and the outlet 350 can also be pipes provided in the shell 310, as long as the connectivity of the inlet 340, the outlet 350 and the inner cavity of the shell 310 can be ensured.

[0070] The partition member 320 may be a partition or the like. The partition member 320 is disposed in the shell 310 to enclose a first chamber 311 in the shell 310. The aforementioned inlet 340 and outlet 350 may be directly connected to the first chamber 311. The first chamber 311 is a working chamber for accommodating and releasing heat exchange medium. In some embodiments, the shell 310 is a closed shell, such as Figure 2-Figure 4 As shown, at this time, the partition component 320 can also enclose the second chamber 312 in the shell 310, and the second chamber 312 and the first chamber 311 can be located on both sides of the partition component 320 respectively; in this embodiment, the partition component 320 and the inner wall surface of the shell 310 can be sealed and contacted, which can ensure the isolation effect of the second chamber 312 and the first chamber 311, thereby preventing the heat exchange medium from entering the second chamber 312 from the first chamber 311, and effectively reducing potential leakage points, thereby reducing the possibility of leakage of the heat exchange medium. In other embodiments, the shell 310 can also be a non-sealed chamber, such as Figure 5 As shown, the left side of the shell 310 is not closed, and at this time, only the first chamber 311 may exist in the shell 310 .

[0071] The first chamber 311 may include an air chamber 311a and a liquid chamber 311b, wherein the air chamber 311a may be located on the upper side of the liquid chamber 311b, the air chamber 311a may be connected to the inlet portion 340, and the liquid chamber 311b may be connected to the outlet portion 350. The condensed working medium may undergo gas-liquid separation in the first chamber 311, wherein the gas phase heat exchange working medium may be gathered in the air chamber 311a, and the liquid phase heat exchange working medium may be gathered in the liquid chamber 311b.

[0072] The active actuator 330 is used to adjust the use state of the partition component 320, which can specifically be a position state, that is, the active actuator 330 is used to drive the partition component 320 to move within the shell 310, and can actively adjust the volume of the first chamber 311 and the second chamber 312 to increase the adjustability of the gas-liquid separator 300 provided in the embodiment of the present application, thereby better adapting to the operating condition fluctuations of the heat exchange system.

[0073] Specifically, when the volume of the first chamber 311 increases, more space can be provided for the gas-phase heat exchange medium, which is beneficial to maintaining the pressure stability inside the system; when the volume of the first chamber 311 decreases, the liquid level of the liquid-phase heat exchange medium can increase, and the liquid level in the first chamber 311 can be maintained, which can largely avoid the situation where the heat exchange medium in the evaporator 100 is evaporated, which is beneficial to ensuring the safe and stable operation of the evaporator 100, and can also largely avoid the discharge of the gas-phase heat exchange medium from the outlet 350 and the impact on the pump body caused thereby, which is also beneficial to ensuring the safe operation of the pump-driven heat exchange system.

[0074] In addition, by adjusting the position of the partition component 320, the volume adjustment range of the working chamber can be larger, which can better adapt to the fluctuation of the operating conditions of the heat exchange system.

[0075] In some embodiments, the gas-liquid separator 300 provided in the embodiment of the present application may also include a monitoring component 360, which may be disposed in the shell 310 to monitor characteristic parameters in the shell 310; the active execution component 330 may be connected to the monitoring component 360 signal, and the active execution component 330 is used to drive the separation component 320 to act according to the characteristic parameters.

[0076] like Figure 2 and Figure 3 As shown, the monitoring component 360 may include a liquid level measuring device for measuring the liquid level of the liquid phase heat exchange medium in the first chamber 311. In this case, the characteristic parameter is the liquid level. In a specific application, if the liquid level is too low, the active actuator 330 may control the partition component 320 to move so as to reduce the volume of the first chamber 311, thereby increasing the liquid level; if the liquid level is too high, the active actuator 330 may control the partition component 320 to move so as to increase the volume of the first chamber 311, thereby decreasing the liquid level.

[0077] Here, the embodiments of the present application do not limit the types of liquid level measuring devices. In practical applications, those skilled in the art can select according to specific needs, as long as they can meet the requirements of use. For example, the above-mentioned liquid level measuring device can be a liquid level meter, such as a drop-in liquid level meter, a float liquid level meter, and a magnetic flap liquid level meter; or, the above-mentioned liquid level measuring device can also use a distance measuring component based on the infrared distance measuring principle, the ultrasonic distance measuring principle, etc., so that the liquid level height can also be measured.

[0078] like Figure 4 As shown, the monitoring component 360 may also include a temperature measuring device or a pressure measuring device. In this case, the monitoring component 360 may be arranged in the air cavity 311a to monitor the temperature value or pressure value of the air cavity 311a. Accordingly, the above characteristic parameter is the temperature value or pressure value of the air cavity 311a. The relationship between the temperature value or pressure value and the volume of the first chamber 311 is not limited here, and it needs to be determined in combination with the actual design. In addition, the embodiments of the present application do not limit the types of temperature measuring devices and pressure measuring devices. In specific practice, those skilled in the art can choose according to actual needs, as long as they can meet the requirements of use; taking the temperature measuring device as an example, it can specifically be a thermistor sensor, a thermocouple sensor, a platinum thermal resistor sensor, etc.

[0079] In addition, the monitoring component 360 can also be a humidity measuring device to detect the humidity in the air cavity 311a or the humidity of the fluid in the inlet portion 340. When the humidity is high, the volume of the first chamber 311 can be controlled to increase to provide sufficient space for the liquid-phase heat exchange medium that is about to be formed in large quantities, and it is beneficial to control the liquid level in the first chamber 311.

[0080] It should be understood that the number of measuring devices included in the monitoring component 360 can be multiple. In this case, different types of measuring devices can be combined to obtain more types of characteristic parameters. In this way, the characteristic parameters based on which the active execution component 330 drives and controls the partition component 320 are more diverse, and can better adapt to the operating condition fluctuations of the heat exchange system; illustratively, the monitoring component 360 can include any two or all of the liquid level measuring device, the temperature measuring device, and the pressure measuring device. For example, it can include a liquid level measuring device and a temperature measuring device at the same time. Accordingly, the characteristic parameters can include the liquid level height and the temperature value. Of course, when the number of measuring devices is multiple, the types of each measuring device can also be the same. Under this condition, the accuracy of the characteristic parameter measurement can be improved by measuring the same characteristic parameter with different measuring devices.

[0081] The specific functional relationship between the position of the partition component 320 in the shell 310 and the characteristic parameter is not limited here. In practical applications, those skilled in the art can set it according to specific needs as long as it can meet the requirements of use. Exemplarily, when there is only one characteristic parameter, for example, when there is only one liquid level height x, the position y of the partition component 320 in the shell 310 and the liquid level height x can be a continuous functional relationship, so that the active actuator 330 can control the partition component 320 to continuously move in the shell 310 based on the continuous functional relationship; or, the position y and the liquid level height x can also be a discontinuous functional relationship, so that the active actuator 330 can control the partition component 320 to move discontinuously in the shell 310 based on the discontinuous functional relationship.

[0082] In some other implementations of the embodiments of the present application, the gas-liquid separator 300 may not include the monitoring component 360. In this case, the characteristic parameters based on which the active execution component 330 drives the partition component 320 may come from external measuring devices, such as measuring devices arranged on the evaporator 100, the condenser 200 and some connecting pipelines, etc. These measuring devices may also be temperature measuring devices or pressure measuring devices, etc.

[0083] like Figure 2 and Figure 4As shown, the active actuator 330 may include a motor 331 and a transmission part 332. The motor 331 may be in transmission connection with the transmission part 332 to drive the transmission part 332 to move. The transmission part 332 may be connected to the partition part 320 to drive the transmission part 332 to move. The motor 331 only needs to be powered on and off to realize its own opening and closing control, without the need for a complex gas circuit structure or liquid circuit structure, and the overall structure is simple; and the motor 331 has a self-locking function, which can better control the position of the partition part 320 in the housing 310, so as to accurately control the volume of the first chamber 311.

[0084] Here, the embodiment of the present application does not limit the specific type of the transmission part 332. In practical applications, those skilled in the art can design it according to specific needs as long as it can meet the requirements of use.

[0085] In some embodiments, the transmission part 332 may be a rack. In this case, the active actuator 330 may also include a transmission gear (not shown in the figure); the motor 331 can drive the transmission gear to rotate. The transmission gear can be directly installed on the rotating shaft of the motor 331, or a transmission member in the form of an intermediate gear can be configured to achieve indirect transmission between the motor 331 and the transmission gear; the transmission gear can mesh with the rack. In this way, when the transmission gear rotates, the rack can move linearly, which can achieve the driving of the partition component 320.

[0086] In other schemes, the transmission part 332 can be a screw. In this case, the active actuator 330 can also include a screw nut (not shown in the figure). The motor 331 can drive the screw nut to rotate. For example, the screw nut can be driven by a worm gear structure. The screw nut and the screw can be threadedly connected. In this way, when the screw nut rotates, the screw can be linearly displaced to drive the partition part 320. In this scheme, the active actuator 330 can also be called an electric screw. It should be understood that as a variation of this scheme, the screw can also be driven by the motor 331 to rotate, and then the screw nut is linearly displaced to drive the partition part 320 to move; or, the partition part 320 and the screw can be directly threadedly connected, which is also feasible.

[0087] During specific assembly, the motor 331 can be arranged outside the housing 310. In this way, the occupation of the internal space of the housing 310 can be reduced, which is conducive to reducing the total volume of the housing 310, and further reducing wind resistance, so as to improve the heat exchange performance of the heat exchange system in a limited space; and it can also increase the movable range of the partition component 320, which is conducive to increasing the adjustable range of the volume of the first chamber 311. Of course, it is also feasible to arrange the motor 331 in the housing 310. In this case, the motor 331 can be specifically located in the second chamber 312, and the housing 310 can also protect the motor 331 to reduce the possibility of damage to the motor 331.

[0088] like Figure 3 As shown, the active execution component 330 may also be a magnetic driving unit 333 , which can generate magnetic force to drive the partition component 320 to move in the housing 310 .

[0089] Specifically, there can be two magnetic drive parts 333, and the two magnetic drive parts 333 can be installed on the partition component 320 and the shell 310 respectively; at least one of the two magnetic drive parts 333 can be an electromagnetic drive part in the form of an electromagnetic coil, so that the polarity of the electromagnetic drive part can be changed by adjusting the flow direction of the current, thereby changing the direction of the force between the two magnetic drive parts 333, so that the displacement direction of the partition component 320 in the shell 310 can be controlled, so as to adjust the volume of the first chamber 311.

[0090] In addition to the above-mentioned motor 331 and magnetic drive unit 333, in the embodiment of the present application, the active actuator 330 can also use other power components as long as they can meet the use requirements. Exemplarily, the active actuator 330 can also be a linear cylinder, a linear oil cylinder, etc.

[0091] The active execution component 330 may be integrated with a controller. In this case, the active execution component 330 may directly obtain the characteristic parameters measured by the monitoring component 360, and control the partition component 320 to move according to the characteristic parameters. Alternatively, an independent controller may be configured, and both the active execution component 330 and the monitoring component 360 may be connected to the controller signal. The controller may obtain the characteristic parameters measured by the monitoring component 360, and then control the active execution component 330 according to the characteristic parameters to drive the partition component 320 to move. This is also feasible.

[0092] Embodiment 3

[0093] Please refer to Figure 6-Figure 7 , Figure 6 This is a schematic structural diagram of a second embodiment of the gas-liquid separator provided in the embodiment of the present application. Figure 7 for Figure 6 A schematic structural diagram of a variant of .

[0094] This embodiment also provides a gas-liquid separator 300, which has basically the same structure as the gas-liquid separator 300 in the aforementioned embodiment 2. The following only describes the differences between this embodiment and embodiment 2. Other undescribed parts can refer to the aforementioned embodiment 2, and no repeated description is made here.

[0095] In the embodiment of the present application, the shell 310 is a closed shell, and the partition component 320 can separate the inner cavity of the shell 310 into a first chamber 311 and a second chamber 312. The use state of the partition component 320 can specifically be a connectivity state, and the connectivity state includes a connectivity state and an isolation state. In the connectivity state, the first chamber 311 and the second chamber 312 can be connected, and the working chamber can include the first chamber 311 and the second chamber 312, and the volume of the working chamber is increased; in the isolation state, the first chamber 311 and the second chamber 312 are isolated, and the working chamber only includes the first chamber 311, and the volume of the working chamber is reduced.

[0096] In some embodiments, Figure 6 As shown, the partition component 320 may be provided with a communication port 321 for connecting the air cavity 311a and the second chamber 312 , and the active actuator 330 includes a switch valve 334 provided at the communication port 321 for controlling the opening and closing of the communication port 321 .

[0097] When the switch valve 334 is in the open state, the partition component 320 is in the connected state, and the air cavity 311a and the second chamber 312 can be connected. At this time, the space for accommodating the gas phase heat exchange medium is expanded, which is conducive to the pressure drop inside the heat exchange system and can better cope with the working condition of excessive pressure in the heat exchange system. When the switch valve 334 is in the closed state, the partition component 320 is in the isolated state, and the first chamber 311 and the second chamber 312 can be isolated.

[0098] It should be understood that the communication port 321 can also be used to connect the liquid chamber 311b and the second chamber 312. In this way, when the switch valve 334 is in the open state, the liquid phase heat exchange medium in the liquid chamber 311b can enter the second chamber 312 through the communication port 321, which can reduce the liquid level in the first chamber 311. Alternatively, multiple communication ports 321 can be configured, such as Figure 7As shown, part of the connecting port 321 can connect the air cavity 311a with the second chamber 312, and the other part of the connecting port 321 can connect the liquid cavity 311b with the second chamber 312. For the convenience of description, the connecting port 321 connecting the air cavity 311a can be called the first connecting port, and the connecting port 321 connecting the liquid cavity 311b can be called the second connecting port. Correspondingly, the switch valve 334 arranged in the first connecting port can be called the first switch valve, and the switch valve 334 arranged in the second connecting port can be called the second switch valve. In specific practice, the first switch valve and the second switch valve can be selectively controlled to open and close as needed, so as to control the air cavity 311a and the liquid cavity 311b to be connected to the second chamber 312 separately or simultaneously.

[0099] In addition to setting the above-mentioned connecting port 321 and the switch valve 334, in some other implementations of the embodiments of the present application, the partition component 320 can also be set as an openable and closable component, such as a door that can be opened and closed by rotating, pushing and pulling, or rolling up, etc. In this way, by controlling the opening and closing of the partition component 320, the connectivity state of the partition component 320 can also be adjusted.

[0100] The opening and closing of the partition component 320 can be driven by the active actuator component 330. The specific structure of the active actuator component 330 is related to the displacement form required for the opening and closing of the partition component 320, which is not limited here. For example, if the opening and closing of the partition component 320 requires rotational displacement, the active actuator component 330 can use a driving motor, a rotary cylinder, or other rotary drive element that can directly output rotational displacement; if the opening and closing of the partition component 320 requires linear displacement, the active actuator component 330 can use a linear cylinder, a linear oil cylinder, or other linear drive element that can directly output linear displacement. Of course, the active actuator component 330 can also use the aforementioned driving motor, rotary cylinder, or other rotary drive element that can directly output rotational displacement. At this time, a displacement conversion mechanism in the form of a gear rack mechanism, a lead screw mechanism, or the like is required to convert the rotational displacement directly output by the rotary drive element into the required linear displacement.

[0101] In this embodiment, in addition to implementing the connectivity state adjustment of the partition component 320, the position state adjustment of the partition component 320 in the second embodiment can also be combined to further increase the adjustability of the gas-liquid separator 300 provided in the embodiment of the present application. Moreover, in the embodiment in which the connectivity state adjustment and the position state adjustment exist at the same time, if the partition component 320 is in a connected state, the pressure of the first chamber 311 and the second chamber 312 can be effectively balanced, the resistance of the partition component 320 when it moves in the shell 310 can be reduced, and the smoothness of the displacement of the partition component 320 in the shell 310 can be improved; in addition, due to the pressure balance between the second chamber 312 and the first chamber 311, it is more conducive to the partition component 320 being stably placed at a designated position in the shell 310, that is, the accuracy and stability of the working chamber volume adjustment can be improved.

[0102] Embodiment 4

[0103] Please refer to Figure 8-Figure 11 , Figure 8 This is a schematic structural diagram of a third embodiment of the gas-liquid separator provided in the embodiments of the present application. Fig. 9 for Figure 8 A structural diagram of a specific solution of the filtering component in FIG. Fig.10 for Figure 8 A structural diagram of another specific solution of the filter component, Fig.11 for Figure 8 A schematic structural diagram of another specific solution of the filter component.

[0104] This embodiment also provides a gas-liquid separator 300, which has basically the same structural form as the gas-liquid separator 300 in the aforementioned embodiment 2 and embodiment 3. The following only describes the differences between this embodiment and embodiment 2 and embodiment 3. Other undescribed parts can refer to the aforementioned embodiment 2 and embodiment 3, and no repeated description is made here.

[0105] like Figure 8 As shown, in the embodiment of the present application, the gas-liquid separator 300 may also include a filter component 370 for filtering the heat exchange medium flowing into or out of the first chamber 311 to filter out impurities that may be present in the heat exchange medium, thereby improving the cleanliness of the heat exchange medium. The specific type of the filter component 370 is not limited here. In practical applications, those skilled in the art can set it as needed, as long as it can meet the requirements of use; illustratively, the filter component 370 can be a screen filter, a quartz sand filter, an activated carbon filter, a multi-media filter, a membrane filter, etc.

[0106] The filter component 370 may be a filter element with a fixed filter area. In this embodiment, the filter component 370 may be disposed at a position where the flow area does not change, such as the inlet 340 and the outlet 350. Of course, the filter component 370 may also be disposed in the first chamber 311, in which case the outer edge of the filter component 370 may be connected to the inner wall surface of the first chamber 311.

[0107] In addition, the filter component 370 may also be a filter component with a variable filter area. In this embodiment, the filter component 370 may be disposed in the first chamber 311, and the filter component 370 may be connected to the partition component 320. When the partition component 320 is displaced in the housing 310, the shape of the filter component 370 may change, and the filter area of ​​the filter component 370 may be adjusted, which may further increase the adjustability of the gas-liquid separator 300 provided in the embodiment of the present application.

[0108] In one specific embodiment, Fig. 9 As shown, in the displacement direction of the partition component 320, at least a part of the filter component 370 can be a folded telescopic part 371, one end of the filter component 370 can be fixedly connected to the inner wall surface of the first chamber 311, and the other end of the filter component 370 can be fixedly connected to the partition component 320. In this way, when the partition component 320 is displaced, the folded telescopic part 371 can be telescoped to adjust the pleat height H and pleat spacing D of the folded telescopic part 371, so that the filtering area of ​​the filter component 370 can be adjusted; and under different pleat heights H and pleat spacings D, the resistance generated by the filter component 370 to the heat exchange medium is different, and accordingly, the influence on the operation of the heat exchange system is also different, which greatly improves the adjustability of the gas-liquid separator 300.

[0109] In another specific embodiment, Fig.10 As shown, the filter component 370 may include a first filter portion 372 and a second filter portion 373 that are slidably connected, the first filter portion 372 may be fixedly connected to the partition component 320, and the second filter portion 373 may be fixedly connected to the inner wall surface of the first chamber 311. In this way, when the partition component 320 is displaced, the area of ​​the overlapped region of the first filter portion 372 and the second filter portion 373 may change, and accordingly, the filtering area of ​​the filter component 370 may change; and when the area of ​​the overlapped region of the first filter portion 372 and the second filter portion 373 changes, the filtering performance of the filter component 370 and the resistance generated to the heat exchange medium are different, and accordingly, the influence on the operation of the heat exchange system is also different, which can also improve the adjustability of the gas-liquid separator 300.

[0110] In this solution, the sliding connection structure between the first filter part 372 and the second filter part 373 is not limited here. In practical applications, those skilled in the art can design it according to actual needs. For example, the first filter part 372 can be provided with a slide rail, and the second filter part 373 can be provided with a slide groove, and the slide rail can be embedded in the slide groove to achieve a sliding connection between the first filter part 372 and the second filter part 373.

[0111] In another specific embodiment, the filter component 370 may include a reel 374 and a retractable filter element 375, the filter element 375 may be wound around the reel 374, and the filter element 375 has an extension 375a; the extension 375a may be fixedly connected to one of the partition component 320 and the inner wall surface of the first chamber 311, and the reel 374 may be fixedly connected to the other of the partition component 320 and the inner wall surface of the first chamber 311. When the partition component 320 moves to increase the volume of the first chamber 311, the size of the extension 375a may increase to increase the filtering area of ​​the filter component 370; and when the partition component 320 moves to reduce the volume of the first chamber 311, the size of the extension 375a may decrease to reduce the filtering area of ​​the filter component 370.

[0112] In this solution, the filter component 370 can also be equipped with a winding box, and the winding shaft 374 and the part of the filter element 375 wound around the filter shaft 374 can be located in the winding box; a torsion spring can also be arranged in the winding box. When the volume of the first chamber 311 increases and the size of the extension 375a increases, the torsion spring can accumulate greater elastic potential energy. In this way, when the volume of the first chamber 311 decreases, the elastic potential energy of the torsion spring can be released to drive more filter elements 375 to be wound around the filter shaft 374, thereby reducing the filtering area.

[0113] In addition to the solution of configuring a torsion spring, a drive motor may also be configured in the winding box to drive the filter element 375 to be wound and released by the drive motor, which is also feasible.

[0114] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
