Description

Technical Field

[0001] The embodiments relate to a coolant supply assembly, and more specifically to a coolant supply assembly for an immersion liquid cooling system. Background Technology

[0002] With the rapid development of the information industry, big data services, new energy storage, and related infrastructure, the cooling needs of data centers, servers, charging piles, and other facilities continue to grow, and immersion liquid cooling technology is receiving increasing attention. In immersion liquid cooling, the heat-generating module is completely submerged in a coolant liquid. The heat generated by the heat-generating module is dissipated through the coolant liquid, which is further cooled through the cooling pipes of a heat exchanger, achieving a continuous cooling effect. Immersion liquid cooling technology is advantageous because of its low thermal resistance and significantly improved heat dissipation efficiency.

[0003] However, during the use of the coolant liquid, the coolant liquid may contain various impurities, such as particles, water and water vapor, as well as precipitates from other components of the cooling circuit (such as heat exchangers and heating modules). Therefore, the physical and chemical properties of the coolant liquid in immersion liquid cooling may change over time, which may adversely affect the normal operation of other components.

[0004] Therefore, it is desirable to develop a coolant supply assembly that is simple in structure and can reliably remove three-phase impurities from the coolant liquid, thereby improving the efficiency and service life of immersion liquid cooling systems. Summary of the Invention

[0005] The purpose of this disclosure is to provide a coolant supply assembly that is simple in structure and can reliably remove three-phase impurities from the coolant liquid, thereby improving the efficiency and service life of an immersion liquid cooling system.

[0006] In one aspect, a coolant supply assembly is provided. The coolant supply assembly includes an upper housing comprising a pre-filter mounting portion, a desiccant mounting portion, a pump mounting portion, and a main filter mounting portion located on a top surface of the upper housing. The upper housing also includes a flange located on a first side surface of the upper housing and a coolant outlet located on a second side surface opposite to the first side surface. The coolant supply assembly further includes: a lower housing to which the upper housing is mounted to define a coolant chamber; a pre-filter assembly mounted to the pre-filter mounting portion; a desiccant unit mounted to the desiccant mounting portion; a pump mounted to the pump mounting portion; a heat exchanger mounted to the flange; and a main filter assembly mounted to the main filter mounting portion.

[0007] The desiccant unit may include a housing, a top cover mounted to the top of the housing, a bottom cover mounted to the bottom of the housing, a gas phase filter molecular sieve, and a liquid phase filter molecular sieve. The top cover, bottom cover, and housing may form an internal volume, with the gas phase filter molecular sieve disposed in the upper part of the internal volume and the liquid phase filter molecular sieve disposed in the lower part of the internal volume.

[0008] The desiccant unit may also include a spring and an adjuster configured to cooperate in automatically adjusting the vertical position of the gas phase filter molecular sieve and the liquid phase filter molecular sieve.

[0009] The regulator may include a base plate portion disposed on top of the molecular sieve of the liquid phase filter, and a plurality of elastic arms extending axially from the base plate portion, the outer diameter of the base plate portion being smaller than the inner diameter of the housing, and each of the plurality of elastic arms including a protrusion extending radially outward from the end of a corresponding one of the plurality of elastic arms, the end being away from the base plate portion.

[0010] The housing may include multiple axial grooves, each receiving a protrusion of one of the multiple elastic arms. A spring may be disposed between the base plate and the bottom surface of the gas-phase filter molecular sieve.

[0011] The desiccant unit can have a rectangular or circular cross-section.

[0012] The coolant supply assembly may also include a pressure relief valve configured to open a bypass passage upstream of the main filter unit when the pressure upstream of the main filter unit exceeds a predetermined pressure.

[0013] The coolant supply assembly may further include a level sensor disposed on a second side surface of the coolant supply assembly and configured to sense the level of coolant liquid within the coolant chamber. The coolant supply assembly may be configured to shut down the pump and trigger an alarm when the coolant liquid level falls below a predetermined level.

[0014] The coolant supply assembly may also include a conductivity sensor disposed within the coolant chamber and configured to sense the conductivity of the coolant liquid within the chamber. The coolant supply assembly may be configured to shut down the pump and trigger an alarm when the conductivity of the coolant liquid exceeds a predetermined conductivity.

[0015] The coolant supply assembly may also include an outlet sensor disposed in an outlet channel and configured to sense the temperature and / or pressure of the coolant liquid in the outlet channel. The coolant supply assembly may be configured to control the pump based on the temperature and / or pressure of the coolant liquid in the outlet channel.

[0016] The coolant supply assembly may have a rectangular cross-section, including a first side surface, a second side surface, a third side surface extending between the first and second side surfaces and adjacent to the pre-filter mounting portion, and a fourth side surface opposite to the third side surface.

[0017] The pre-filter mounting part can be located at the corner between the second and third side surfaces, the desiccant mounting part can be located at the corner between the second and fourth side surfaces, the pump mounting part can be located at the corner between the first and fourth side surfaces, and the main filter mounting part can be located at the corner between the first and third side surfaces.

[0018] Heat exchangers may include evaporators.

[0019] The coolant supply assembly may also include a breather valve.

[0020] On the other hand, an immersion liquid cooling system including a coolant supply component is provided.

[0021] The above-described layout of the coolant supply components reduces overall space, eliminates various connecting pipes and / or hoses, and significantly reduces assembly time and cost.

[0022] The spring works in conjunction with the regulator to automatically adjust the vertical position of the gas phase filter molecular sieve and the liquid phase filter molecular sieve, thereby reducing the relative movement between the gas phase filter molecular sieve and the liquid phase filter molecular sieve, thus reducing wear between the gas phase filter molecular sieve and the liquid phase filter molecular sieve, and extending the service life of the gas phase filter molecular sieve and the liquid phase filter molecular sieve.

[0023] Furthermore, if the coolant level rises, the buoyancy acting on the base plate also increases, which counteracts the spring force, thus compressing the spring further and pushing the gas-phase filter molecular sieve upwards. In this way, the gas-phase filter molecular sieve is always positioned above the coolant level, preventing it from failing due to immersion in the coolant.

[0024] By integrating a pre-filter, a desiccant unit, and a main filter, the coolant supply assembly can reliably remove three-phase impurities from the coolant liquid, thereby improving the efficiency and service life of the immersion liquid cooling system.

[0025] By integrating a pressure relief valve, breather valve, level sensor, outlet sensor, conductivity sensor, and inlet pressure sensor, the coolant supply assembly can operate reliably, thereby improving the efficiency and service life of the immersion liquid cooling system.

[0056] The pre-filter device 3 is installed into the pre-filter mounting section 130. According to an example, such as...

The pre-filter mounting portion 130 is provided with a coolant inlet 11 configured to receive coolant liquid returned from the heating module, an outlet port 132 configured to supply filtered coolant liquid to the coolant chamber, and a mating thread 131.

As those skilled in the art will understand, the pre-filter device 3 can be installed into the pre-filter mounting portion 130 by any other suitable means, such as a snap-fit ​​connection, without departing from the scope of this disclosure.

[0057] Desiccant unit 7 is installed into desiccant mounting section 170. Pump 5 is installed into pump mounting section 150, and heat exchanger 6 is installed into flange section 160 and via heat exchanger inlet channel 161. Figure 5 Pump 5 receives coolant liquid to be cooled.

Figure 4As shown, the main filter assembly 4 includes a main filter body, a main filter element 42, and a thread 41 located on the outer periphery of the main filter body. An annular unfiltered space 43 exists between the main filter body and the main filter element 42, configured to pass through the heat exchanger outlet channel 162. Figure 6 The main filter mounting section 140 receives cooled coolant liquid from the heat exchanger 6. The main filter mounting section 140 is provided with a mating thread 141 and an outlet channel 148. Figure 7 The filter outlet channel 142 is connected. Therefore, the main filter assembly 4 is installed to the main filter mounting portion 140 by a threaded connection. As those skilled in the art will understand, the main filter assembly 4 can be installed to the main filter mounting portion 140 by any other suitable means, such as a snap-fit ​​connection, without departing from the scope of this disclosure.

[0059] The above-described layout of the coolant supply assembly 100 reduces the overall space, eliminates various connecting pipes and / or hoses, and significantly reduces assembly time and cost.

[0060] Pressure relief valve 9 is installed at pressure relief port 190 ( Figure 8 In, and configured to open the bypass channel 191 upstream of the main filter device 4 when the pressure upstream of the main filter device 4 exceeds a predetermined pressure. Figure 7 ).

[0061] A liquid level sensor 101 is disposed in a sensor port 1010 on the second side surface 122 of the coolant supply assembly 100 and configured to sense the liquid level of the coolant liquid in the coolant chamber. When the liquid level of the coolant liquid is lower than a predetermined level, the coolant supply assembly 100 shuts off the pump 5 and triggers an alarm.

[0062] The conductivity sensor 103 is disposed in the coolant chamber and configured to sense the conductivity of the coolant liquid in the coolant chamber.

[0063] An outlet sensor 102 is disposed in an outlet channel 148 and configured to sense the temperature and / or pressure of the coolant liquid in the outlet channel 148. The coolant supply assembly 100 controls the pump 5 based on the temperature and / or pressure of the coolant liquid in the outlet channel 148.

[0064] The pre-filter device 3 and the main filter device 4 are particulate filters. The pre-filter device 3 is configured to filter out impurities in the coolant liquid returning from the heating module. According to one example, the coolant supply assembly 100 can be used in an immersion liquid cooling system for an electric vehicle, and the heating module can be a battery module used in an electric vehicle. As those skilled in the art will understand, the coolant supply assembly 100 can be used in any other suitable immersion liquid cooling system, such as an immersion liquid cooling system for a big data server, without departing from the scope of this disclosure.

Figure 16 yes Figure 1 A schematic perspective view of the breather valve 8 of the coolant supply assembly 100.

[0069] According to one example, the desiccant unit 7 may have a rectangular cross-section. As those skilled in the art will understand, the desiccant unit 7 may have any other suitable cross-section, such as a circular cross-section, without departing from the scope of this disclosure.

[0070] Figure 15 This is a schematic perspective view of the desiccant unit 7 of a coolant supply assembly 100 according to another embodiment. The desiccant unit 7 may include a housing 73, an upper cover 71 mounted to the top of the housing 73, a lower cover 72 mounted to the bottom of the housing 73, a gas phase filter molecular sieve 76, and a liquid phase filter molecular sieve 77, wherein the upper cover 71, the lower cover 72, and the housing 73 form an internal volume. The gas phase filter molecular sieve 76 is disposed in the upper part of the internal volume, and the liquid phase filter molecular sieve 77 is disposed in the lower part of the internal volume. Although Figure 15 The desiccant unit 7 shown has a circular cross-section; however, as those skilled in the art will understand, the desiccant unit 7 may have any other suitable cross-section, such as a rectangular cross-section, without departing from the scope of this disclosure. The gas phase filter molecular sieve 76 is located above the coolant liquid level, thereby absorbing impurities and water vapor from the air above the coolant liquid to prevent impurities from dissolving in the coolant liquid and causing an increase in the dielectric constant of the coolant liquid. The liquid phase filter molecular sieve 77 is disposed in the coolant liquid, thereby absorbing moisture and other conductive impurities in the coolant liquid.

[0071] The upper cover 71 and the lower cover 72 can be installed onto the housing 73 by threaded engagement or snap-fit ​​connection. As those skilled in the art will understand, the upper cover 71 and the lower cover 72 can be installed onto the housing 73 by any other suitable means without departing from the scope of this disclosure.

[0072] The desiccant unit 7 may also include a spring 74 and an adjuster 75, which cooperate to automatically adjust the vertical position of the gas phase filter molecular sieve 76 and the liquid phase filter molecular sieve 77.

[0073] Figure 19 yes Figure 15 A schematic perspective view of the regulator 75 of the desiccant unit 7. The regulator 75 may include a base plate 171 disposed on top of the molecular sieve 77 of the liquid phase filter, and a plurality of elastic arms 172 extending axially from the base plate 171. The outer diameter of the base plate 171 is slightly smaller than the inner diameter of the housing 73. Each elastic arm 172 is provided with a protrusion 173 extending radially outward from the end of the elastic arm 172 away from the base plate 171. The housing 73 is provided with a plurality of axial grooves 78. Figure 15The spring 74 is configured to receive the corresponding protrusion 173. The spring 74 is disposed between the base plate 171 and the bottom surface of the gas phase filter molecular sieve 76. Figure 15 As shown, there are four elastic arms 172 and four axial grooves 78. As those skilled in the art will understand, the number of elastic arms 172 and axial grooves 78 can be any other suitable number, such as three, five, etc., without departing from the scope of this disclosure.

[0074] Spring 74 cooperates with regulator 75 to automatically adjust the vertical position of gas-phase filter molecular sieve 76 and liquid-phase filter molecular sieve 77, thereby reducing the relative movement between them, reducing wear, and extending their service life. Additionally, if the coolant level changes (e.g., rises), the buoyancy acting on the base plate 171 changes, resisting the spring force of spring 74, causing spring 74 to move (e.g., be further compressed), thus pushing the gas-phase filter molecular sieve 76 (e.g., upwards). In this way, the gas-phase filter molecular sieve 76 is always positioned above the coolant level, preventing it from failing due to immersion in the coolant.

[0075] The gas phase filter molecular sieve 76 leaks, with its upper part exposed to air, to filter impurities in the air and prevent them from dissolving in the coolant and causing an increase in the dielectric constant. First, spring 74 and regulator 75 are installed in the lower part, then liquid phase filter molecular sieve 77 is added and covered with a lower cover 72. The lower part is immersed in coolant to remove conductive impurities from the coolant. An adjustable spring mechanism is used in the middle to ensure the distribution of the two molecular sieves. The potential energy of spring 74 is used to reduce the relative movement between the molecular sieves, thereby reducing wear between the molecular sieves and preventing molecular sieve failure.

[0076] According to one example, the coolant liquid may be cooling oil. As those skilled in the art will understand, the coolant liquid may consist of any other suitable coolant without departing from the scope of this disclosure.

[0077] The operation of the coolant supply assembly 100 is now described. Coolant liquid returns from the heating module and flows into the pre-filter device 3 via coolant inlet 11. The coolant liquid flows through the pre-filter device 3, where impurities are filtered out. The filtered coolant liquid exits through outlet port 132. Figure 3The coolant flows into the coolant chamber. The gas phase filter molecular sieve 76 absorbs impurities and water vapor from the air above the coolant liquid to prevent these impurities from dissolving in the coolant liquid and increasing its dielectric constant. The liquid phase filter molecular sieve 77 absorbs moisture and other conductive impurities from the coolant liquid. Pump 5 pumps the coolant liquid from the coolant chamber to the heat exchanger 6 via the heat exchanger inlet channel 161, based on the temperature and / or pressure of the coolant liquid in the outlet channel 148. The cooled coolant liquid flows through the heat exchanger outlet channel 162 to the annular unfiltered space 43 of the main filter assembly 4 and flows through the main filter element 42. The cooled and filtered coolant liquid flows through the filter outlet channel 142 and outlet channel 148, and is supplied to the heating module via the coolant outlet 12.

[0078] Various aspects of this disclosure have been described in detail with reference to the illustrated embodiments; however, those skilled in the art will recognize that many modifications can be made thereto without departing from the scope of this disclosure. This disclosure is not limited to the precise structure and composition disclosed herein; any and all modifications, variations, and modifications apparent from the foregoing description are within the scope of this disclosure as defined by the appended claims.
