[0001] [Corrected on 13.12.2024 according to Rule 91] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on May 30, 2023, with application number 202310630409.0 and application name “Liquid cooling module, electronic equipment and accessories”, the entire contents of which are incorporated herein by reference. [Corrected 13.12.2024 according to Rule 91] Technical field

[0002] [Corrected 13.12.2024 according to Rule 91] The present application relates to the technical field of electronic equipment, and in particular to liquid cooling modules, electronic equipment and accessories. [Corrected 13.12.2024 according to Article 91] Background

[0003] [Corrected 13 / 12 / 2024 in accordance with Rule 91] A liquid cooling module may include a pump and a working fluid. The working fluid can be understood as a medium for converting thermal energy into mechanical energy. The pump serves as a power source for the working fluid, providing motive force for its flow. During its flow, the working fluid acts as a heat transfer medium, enabling the liquid cooling module to achieve heat dissipation.

[0004] [Corrected 13 / 12 / 2024 in accordance with Rule 91] In recent years, it has become possible to visualize the flow of working fluids, creating a technologically advanced flow display area. Related art discloses working fluids with visualizable flow states, including water and dyes. The presence of dyes can enhance the color of the working fluid, allowing for a visual display of the working fluid's flow.

[0005] [Corrected 13.12.2024 in accordance with Rule 91] Colored working fluids can visualize the flow of liquid cooling modules in larger sizes. Liquid cooling modules used in electronic devices are relatively small (typically, the cavity size of a liquid cooling module is on the order of microliters), and the flow visualization of working fluids in electronic devices disclosed in related art is poor. [Corrected 13.12.2024 in accordance with Rule 91] Summary of the invention

[0006] [Corrected 13 / 12 / 2024 in accordance with Rule 91] This application discloses a liquid cooling module, electronic equipment, and accessories.

When the temperature inside the electronic device 1 is too high, it will affect the working efficiency of the electronic functional components and the service life of the electronic device 1. Therefore, a liquid cooling module 10 needs to be provided to control the temperature rise of the electronic functional components.

[0123] [Corrected 13.12.2024 according to Rule 91] During the flow process, the working fluid can act as a carrier for heat transfer, carrying heat away from the electronic functional components, thereby achieving temperature control of the electronic functional components.

[0124] [Corrected on 13.12.2024 according to Rule 91] In the embodiment of the present application, the cavity of the liquid-cooling module 100 provides a flow track / place for the flow of the working medium. Therefore, in the embodiment of the present application, the cavity of the liquid-cooling module 100 can be called a flow channel.

[0125] [Corrected on 13.12.2024 according to Rule 91] The embodiment of the present application does not specifically limit the type of pump 200.

[0129] [Corrected 13.12.2024 according to Rule 91] Colored working fluids can visualize the flow of liquid cooling modules 10 in larger sizes. Liquid cooling modules 10 used in electronic devices are relatively small (typically, the cavity size of the liquid cooling module 10 is typically on the order of microliters), and the flow visualization of working fluids in electronic devices disclosed in related art is poor.

[0130] [Corrected 13.12.2024 in accordance with Rule 91] To address the technical issues of the related art, referring to Figure 3 , the first aspect of the present application discloses a working fluid.

During the movement of the working fluid, liquid interface A moves relative to cavity B, which contains the working fluid. This allows for visualization of the flow of working fluid 300 .

[0131] [Corrected 13.12.2024 according to Rule 91] The following is a further description of the components of the working fluid disclosed in the examples of this application:

[0132] [Corrected 13.12.2024 according to Rule 91] The working fluid disclosed in the embodiments of this application includes: a first medium. The first medium has excellent heat dissipation performance, ensuring that the working fluid can achieve optimal temperature control; and the first medium needs to form a liquid interface with the second phase to ensure that the working fluid can achieve flow visualization.

[0133] [Corrected 13.12.2024 according to Rule 91] As a feasible implementation, the mass fraction of the first medium in the working medium is greater than or equal to 80%. For example, the mass fraction of the first medium in the working medium may include: 85%, 90%, 95%, etc.

[0134] [Corrected 13.12.2024 according to Rule 91] In this implementation, the mass fraction of the first medium in the working fluid is greater than or equal to 80%, that is, the working fluid contains a large amount of the first medium (the first medium has better heat dissipation performance), ensuring that the working fluid can achieve better heat dissipation performance. The working fluid absorbs more heat when changing unit temperature, and the working fluid can achieve better temperature control function.

[0135] [Corrected on 13.12.2024 according to Rule 91] The embodiments of the present application do not specifically limit the type of medium included in the first medium. Any medium that has good heat dissipation performance and can form a liquid interface with the second phase can be used as the first medium in the embodiments of the present application.

[0136] [Corrected 13.12.2024 according to Rule 91] For example, in some feasible implementations, the first medium may include: water (H2O), liquid metal, etc.

[0137] [Corrected 13.12.2024 according to Rule 91] In the embodiments of the present application, H2O and liquid metal have excellent heat dissipation performance. Using H2O and liquid metal as the first medium enables the working fluid to achieve excellent heat dissipation performance and ensures that the working fluid can achieve optimal temperature control.

[0138] [Corrected 13.12.2024 according to Rule 91] In the embodiments of the present application, the working fluid may further include: a water-soluble salt. A solution formed by a water-soluble salt and water (the first medium) may be referred to as a salt solution.

[0139] [Corrected 13.12.2024 according to Rule 91] Salt solutions may contain anions and cations. Both anions and cations have strong hydrophilic properties. This allows anions to form hydrated anions with H2O, and cations to form hydrated cations with H2O. In other words, H2O tends to combine with cations and anions.

[0140] [Corrected 13.12.2024 in accordance with Rule 91] When the second phase is dispersed in the form of small droplets within HO to form an emulsion, the HO preferentially combines with cations and anions, reducing the thickness of the hydration layer on the surface of the droplets. The droplets tend to aggregate to form the second phase, thereby restoring the liquid interface between the first medium and the second phase. Therefore, the working fluid disclosed in this implementation has a stable liquid interface, and a liquid cooling module employing this working fluid can achieve stable flow visualization.

[0141] [Corrected 13.12.2024 according to Rule 91] The embodiment of the present application does not specifically limit the color of the above-mentioned salt solution. In a feasible implementation method, the salt solution can be a colorless solution.

[0142] [Corrected 13.12.2024 according to Rule 91] In the embodiments of the present application, the colorless solution may include: H2O (solvent) and a colorless salt (solute). The colorless salt may be understood as a salt whose aqueous solution is colorless. Exemplary colorless salts may include, but are not limited to: sodium chloride (NaCl), magnesium chloride (MgCl2), calcium chloride (CaCl2) solution, aluminum nitrate (Al(NO3)4), etc.

[0143] [Corrected 13.12.2024 according to Rule 91] In order to further improve the visualization of the working fluid flow, as a feasible implementation method, the salt solution can include: a colored solution.

[0144] [Corrected 13.12.2024 according to Rule 91] In the embodiment of the present application, the colored solution may include: H2O and a colored salt. Among them, the colored salt can be understood as a salt that develops color in the aqueous solution. Exemplarily, the colored salt may include, but is not limited to: copper sulfate (CuSO4), copper chloride (CuCl2), copper nitrate (Cu(NO3)2), ferrous sulfate (FeSO4), ferrous chloride (FeCl2), ferrous nitrate (Fe(NO3)2), ferric sulfate (Fe2(SO4)3), ferric chloride (FeCl3), ferric nitrate (Fe(NO3)3), potassium permanganate (KMnO4), cobalt chloride (CoCl2·n(H2O)), cobalt sulfate (CoSO4), cobalt nitrate (Co(NO3)2), nickel chloride (NiCl2), nickel sulfate (NiSO4), nickel nitrate (Ni(NO3)2), etc.

[0145] [Corrected 13.12.2024 according to Rule 91] The colored salt can change the color of the first medium. Therefore, in the embodiments of the present application, the colored salt can also be referred to as a water-soluble dye or an inorganic dye.

[0146] [Corrected 13.12.2024 in accordance with Rule 91] In this implementation, the working fluid includes a water-soluble dye. The water-soluble dye has a greater solubility in the first medium than in the second phase. The water-soluble dye can impart color to the first medium. The introduction of the water-soluble dye can create a greater color contrast between the first medium and the second phase, thereby providing a significant flow visualization effect for the working fluid.

[0147] [Corrected 13.12.2024 according to Article 91] The properties of the first medium are further explained below:

[0148] [Corrected 13.12.2024 according to Rule 91] Heat dissipation performance can be understood as the amount of heat absorbed or released per unit temperature change of a medium. The better the heat dissipation performance of a medium, the more heat it absorbs or releases per unit temperature change, and the more effective the temperature control effect of the medium.

[0149] [Corrected 13.12.2024 according to Article 91] Thermal conductivity can be understood as the thermal conductivity of a medium (area: 1m2) under stable heat transfer conditions (e.g. constant pressure P, constant temperature T). 2 The higher the thermal conductivity of the medium, the more heat it absorbs per unit length of the first medium per unit temperature change, and the more significant the temperature control effect of the corresponding working fluid.

[0150] [Corrected 13.12.2024 according to Rule 91] As a feasible implementation, at 25°C, the thermal conductivity of the first medium is greater than or equal to 0.1 W / m·K. For example, at 25°C, the thermal conductivity of the first medium may be 0.1 W / m·K, 0.2 W / m·K, 0.3 W / m·K, etc.

[0151] [Corrected 13.12.2024 according to Rule 91] It is worth noting that the thermal conductivity of the first medium is not a fixed value. Temperature will affect the thermal conductivity of the first medium. Specifically, an increase in temperature will intensify the molecular thermal motion of the first medium, allowing the heat to transfer more heat to the medium, that is, the thermal conductivity of the first medium will increase as the temperature rises. Unless otherwise specified, the thermal conductivity involved in the embodiments of the present application can be understood as the thermal conductivity of the first medium at 25°C.

[0152] [Corrected 13 / 12 / 2024 according to Rule 91] In this implementation, at 25°C, the thermal conductivity of the first medium is greater than or equal to 0.1 W / m·K. The first medium has a relatively high thermal conductivity, and the first medium absorbs a relatively large amount of heat per unit length per unit temperature change, thereby enabling the working medium to achieve better temperature control.

[0153] [Corrected 13 / 12 / 2024 according to Rule 91] Specific heat capacity can be understood as the heat capacity per unit mass of the first medium. The higher the specific heat capacity of the first medium, the more heat per unit mass of the first medium absorbs per unit temperature change, and the more significant the temperature control function of the corresponding working medium.

[0154] [Corrected 13.12.2024 according to Rule 91] It is worth noting that the specific heat capacity of the first medium is affected by temperature. Unless otherwise specified, the specific heat capacity involved in the embodiments of this application can be understood as the specific heat capacity of the first medium at 25°C.

[0155] [Corrected 13.12.2024 according to Rule 91] To ensure the temperature control function of the working medium, as a feasible implementation method, the specific heat capacity of the first medium at 25°C is greater than or equal to 1000 J / kg·°C. For example, at 25°C, the specific heat capacity of the first medium can be: 1000 J / kg·°C, 1500 J / kg·°C, 1500 J / kg·°C, etc.

[0156] [Corrected 13.12.2024 according to Rule 91] In this implementation, at 25°C, the specific heat capacity of the first medium is greater than or equal to 1000 J / kg·°C. The first medium has a large specific heat capacity, and unit mass of the first medium absorbs a large amount of heat per unit temperature change, thereby enabling the working medium to achieve better temperature control.

[0157] [Corrected 13 / 12 / 2024 according to Rule 91] Viscosity can be understood as the resistance of the first medium to flow. Specifically applied to the embodiments of the present application, the lower the viscosity of the first medium, the less resistance the first medium encounters during flow, the more heat the first medium transfers per unit time, and the more significant the temperature control function of the working fluid.

[0158] [Corrected 13.12.2024 according to Rule 91] It is worth noting that the viscosity of the first medium is affected by temperature. Unless otherwise specified, the viscosity involved in the embodiments of this application can be understood as the viscosity of the first medium at 25°C.

[0159] [Corrected 13.12.2024 according to Rule 91] As a feasible implementation, at 25°C, the viscosity of the first medium may be less than or equal to 50 cp. For example, at 25°C, the viscosity of the first medium may be 50 cp, 40 cp, 30 cp, 20 cp, 10 cp, etc.

[0160] [Corrected 13.12.2024 according to Rule 91] In this implementation, at 25°C, the viscosity of the first medium is less than or equal to 50 cp. The first medium has a lower viscosity, and thus encounters less resistance during flow. The first medium can transfer more heat per unit time, and the working medium can achieve better temperature control.

[0161] [Corrected 13.12.2024 in accordance with Rule 91] This completes the description of the first medium.

In some feasible implementations, the molecular structure of the heteroatom compound can include: wait.

[0188] [Corrected 13.12.2024 according to Rule 91] In this implementation, the molecular structure of the heteroatom compound (second medium) includes: benzene ring The benzene ring has greater rigidity, which in turn makes the heteroatom compound have greater rigidity. When the heteroatom compound is emulsified with the first medium, due to the greater rigidity of the heteroatom compound, under the action of the demulsifier, the heteroatom compound can quickly break away from the constraints of the first medium and aggregate into a second phase, allowing the working fluid to restore the liquid interface and achieve flow visualization effect.

[0189] [Corrected 13.12.2024 in accordance with Rule 91] In some feasible embodiments, the working fluid may further include an organic dye. The solubility of the organic dye in the second medium is greater than that in the first medium. The introduction of the organic dye can increase the color contrast between the first medium and the second phase, thereby providing a significant flow visualization effect for the working fluid.

[0190] [Corrected 13.12.2024 in accordance with Article 91] This completes the description of the second phase.

[0191] [Corrected 13 / 12 / 2024 in accordance with Rule 91] It is worth noting that when the working medium is stationary, a liquid interface exists between the first and second media. When the working medium is flowing, emulsification may occur between the first and second media, i.e., the second medium is dispersed in the first medium in the form of small droplets. Specifically, as shown in Figure 4, after the first and second media emulsify, the second medium is dispersed in the second medium in the form of small droplets, forming an emulsion 400. This destroys the liquid interface between the first and second media, thus depriving the working medium of flow visualization.

[0192] [Corrected 13.12.2024 in accordance with Rule 91] To achieve a working fluid with stable flow visualization, as a feasible implementation, the working fluid may further include a demulsifier. The demulsifier can break up the emulsion, thereby restoring the liquid interface between the first medium and the second phase, thereby ensuring a stable liquid interface and enabling stable flow visualization.

[0193] [Corrected on 13.12.2024 according to Rule 91] The embodiments of the present application do not make specific limitations on demulsifiers. Any auxiliary agent that can destroy the emulsion formed by the second phase and the first medium can be used as a demulsifier in the embodiments of the present application.

[0195] [Corrected 13.12.2024 according to Rule 91] In some feasible implementations, the hydrophilic-lipophilic balance value of the demulsifier is between 1 and 20, so that the demulsifier can be present at the liquid interface between the first medium and the second phase, playing a role in stabilizing the liquid interface, so that the working fluid has a stable flow visualization effect.

[0196] [Corrected 13.12.2024 according to Rule 91] As a feasible implementation method, the molecular structure of sodium alkylnaphthalene sulfonate includes:

[0199] [Corrected 13.12.2024 in accordance with Article 91] It is worth noting that It is only an exemplary display of the R and sulfonic acid groups (SO3Na - ) substitution position, the above substitution position does not constitute a limitation. For example: in some feasible implementations, SO3Na - Can be combined with naphthalene ring For another example, in some feasible implementations, R can be connected to C5, C6, or C8 on the naphthalene ring.

[0200] [Corrected 13.12.2024 according to Rule 91] In this implementation, the molecular structure of sodium alkylnaphthalene sulfonate includes: (SO3Na - ), so that the binding ability of sodium alkylnaphthalene sulfonate with the first medium is stronger than the binding ability of the second medium with the first medium. When the second medium is dispersed in the first medium in the form of small droplets to form an emulsion, the first medium preferentially binds to SO3Na - The combination causes the thickness of the hydration layer on the surface of the droplets to decrease, and the droplets tend to aggregate with each other to form a second phase, thereby restoring the liquid interface between the first medium and the second phase.

[0201] [Corrected 13 / 12 / 2024 in accordance with Rule 91] Furthermore, the molecular structure of sodium alkylnaphthalene sulfonate includes a naphthalene ring. This naphthalene ring possesses significant rigidity, which in turn ensures the demulsifier possesses significant rigidity. When the second phase is emulsified with the first medium, the second phase is dispersed within the first medium in the form of small droplets. Due to the demulsifier's high rigidity, it can quickly reach the surface of the droplets, freeing them from the constraints of the first medium and aggregating into the second phase. This results in a more efficient demulsification process, allowing the working fluid to quickly recover at the liquid interface.

[0202] [Corrected 13.12.2024 according to Rule 91] It is considered that the demulsification efficiency of the demulsifier is related to the rigidity of the demulsifier. Specifically, the more carbon atoms in the main chain of the demulsifier, the longer the molecular chain of the demulsifier, the weaker the rigidity of the demulsifier, and the lower the demulsification efficiency of the demulsifier.

Specifically, the larger the relative molecular mass of the demulsifier, the higher the boiling point of the demulsifier, the better the demulsifier stability, the more stable the liquid interface between the second phase and the first medium, and the more stable the working medium flow visualization effect.

[0205] [Corrected 13.12.2024 according to Rule 91] In order to obtain a working fluid with a stable flow visualization effect, as a feasible implementation method, The number of carbon atoms in the main chain of R is greater than or equal to 1.

[0222] [Corrected 13 / 12 / 2024 in accordance with Rule 91] When the first medium includes water, the working fluid may experience injection problems, causing it to adhere to the inner wall of the cavity. Specifically, during injection into the inner wall of the cavity, the water in the working fluid has a high surface tension, making it difficult for the working fluid to penetrate the inner wall of the cavity. Consequently, the working fluid adheres to the inner wall of the cavity, resulting in wall sticking. Specifically, referring to Figure 5, it can be seen that the working fluid 300 adheres to the inner wall of the cavity inner wall B.

The rigid base 131 is disposed between the top cover layer 120 and the bottom cover layer 140 to support the top cover layer 120 and the bottom cover layer 140.

[0269] [Corrected 13.12.2024 in accordance with Rule 91] The rigid base 131 is also used to separate the flow channels of the cavity 110 into at least one liquid inlet channel 1101 and at least one liquid outlet channel 1102. The liquid inlet channel 1101 and the liquid outlet channel 1102 are both formed by the rigid base 131, the top cover layer 120, and the bottom cover layer 140. The liquid inlet channel 1101 is connected to the liquid cooling inlet 112, and the liquid outlet channel 1102 is connected to the liquid cooling outlet 111. The separation of the liquid inlet channel 1101 and the liquid outlet channel 1102 by the rigid base 131 helps prevent the cooling medium in the liquid inlet channel 1101 and the liquid outlet channel 1102 from mixing and affecting the heat dissipation effect.

[0270] [Corrected 13.12.2024 according to Rule 91] As a feasible implementation, the top cover layer 120, the rigid base 131, and the bottom cover layer 140 can be an integrated structure. This ensures that the liquid inlet channel 1101 and the liquid outlet channel 1102 formed by the top cover layer 120, the rigid base 131, and the bottom cover layer 140 have a good sealing effect, thereby preventing leakage of the working fluid 300.

[0271] [Corrected 13.12.2024 according to Rule 91] It should be noted that in the implementation method in which the top cover layer 120, the rigid base 131 and the bottom cover layer 140 are an integrated structure, the top cover layer 120, the rigid base 131 and the bottom cover layer 140 are all made of transparent materials so that the liquid cooling module can achieve a flowable visualization effect.

[0272] [Corrected 13.12.2024 in accordance with Rule 91] As a feasible implementation, the top cover layer 120, rigid substrate 131, and bottom cover layer 140 can be separate structures. They can be connected using screws, high-temperature adhesive bonding, UV light-curing adhesive bonding, hot press bonding, hot melt welding, ultrasonic welding, or ultraviolet wave welding. In this implementation, the top cover layer 120, rigid substrate 131, and bottom cover layer 140 can be made of the same or different materials. However, at least one of the top cover layer 120 and the bottom cover layer 140 must be transparent.

[0273] [Corrected 13.12.2024 according to Rule 91] In one embodiment, the difference between the melting temperature of the covering layer (120, 140) and the melting temperature of the rigid base 131 is less than or equal to 20°C. The small difference in melting temperature between the covering layer (120, 140) and the rigid base 131 facilitates the forming of an integrated structure of the covering layer (120, 140) and the rigid base 131 by sealing and welding, thereby improving the sealing effect of the liquid inlet channel 1101 and the liquid outlet channel 1102.

[0274] [Corrected 13.12.2024 according to Rule 91] Sealing welding may include high-temperature connection methods such as press-bonding sealing welding, hot melt welding, ultrasonic welding, and ultra-high frequency welding without solder paste. Hot press sealing is usually performed in a high-temperature environment. If the difference in thermal expansion coefficient between the cover layer (120, 140) and the rigid base 131 is large, the cover layer (120, 140) and the rigid base 131 may warp, thereby reducing the sealing effect of the liquid inlet channel 1101 and the liquid outlet channel 1102 enclosed by the cover layer (120, 140) and the rigid base 131.

[0275] [Corrected 13.12.2024 according to Rule 91] In order to further improve the sealing effect of the liquid inlet channel 1101 and the liquid outlet channel 1102, as a feasible implementation method, the difference between the thermal expansion coefficient of the cover layer (120, 140) and the thermal expansion coefficient of the rigid base 131 is less than or equal to ≤10*10 -6 / (℃).

[0276] [Corrected 13.12.2024 according to Rule 91] In this implementation, the difference between the thermal expansion coefficient of the cover layer (120, 140) and the thermal expansion coefficient of the rigid base 131 is less than or equal to ≤10*10 -6 / °C. The difference in thermal expansion coefficient between the covering layer (120, 140) and the rigid base 131 is small, which can reduce the warping of the covering layer (120, 140) and the rigid base 131 during the sealing welding process to a certain extent, and ensure that the liquid inlet flow channel 1101 and the liquid outlet flow channel 1102 surrounded by the covering layer (120, 140) and the rigid base 131 have a good sealing effect.

[0277] [Corrected 13.12.2024 according to Rule 91] As a feasible implementation, the thickness of the cover layer (120, 140) is less than 2 mm. In this implementation, the thickness of the cover layer (120, 140) is less than or equal to less than 2 mm. On the one hand, it can realize a lightweight liquid cooling module 10. On the other hand, it can realize a liquid cooling module 10 with a significant flow visualization effect.

[0278] [Corrected 13.12.2024 according to Rule 91] In order to prevent the evaporation loss of the working fluid during long-term operation from affecting the reliability of the liquid cooling module, as a feasible implementation method, an anti-evaporation layer is provided on the surface of the cover layer (120, 140). The embodiment of the present application does not specifically limit the position of the anti-evaporation layer. As a feasible implementation method, the anti-evaporation layer can be provided on the side of the cover layer (120, 140) adjacent to the working fluid. As a feasible implementation method, the anti-evaporation layer can be provided on the side of the cover layer (120, 140) away from the working fluid.

[0279] [Corrected on 13.12.2024 according to Rule 91] In the embodiment of the present application, the density of the anti-evaporation layer is greater than the density of the covering layer. The provision of the anti-evaporation layer can increase the difficulty for the working fluid to escape from the cavity, that is, the anti-evaporation layer plays a role in reducing the evaporation loss of the working fluid.

[0280] [Corrected 13.12.2024 according to Rule 91] In addition, the visible light transmittance of the anti-evaporation layer is greater than or equal to the threshold value to ensure the flow visualization effect of the liquid cooling module.

[0281] [Corrected 13.12.2024 in accordance with Rule 91] The present embodiments do not impose specific restrictions on the materials used for the anti-evaporation layer. Any material that can prevent evaporation loss of the working fluid can be used as the anti-evaporation layer in the present embodiments. Exemplary materials for the anti-evaporation layer may include at least one of a polyimide layer, a polyvinylidene chloride layer, or a metal film layer.

[0282] [Corrected 13.12.2024 according to Rule 91] In this implementation, an anti-evaporation layer is provided on the surface of the cover layer (120, 140). The anti-evaporation layer can prevent evaporation loss of the working fluid, thereby ensuring the long-term reliability of the liquid cooling module. At the same time, the visible light transmittance of the anti-evaporation layer is greater than or equal to a threshold value, thereby ensuring the flow visualization effect of the liquid cooling module.

[0283] [Corrected 13.12.2024 according to Rule 91] The heat dissipation performance of the working fluid disclosed in the embodiments of this application is described below with reference to specific data:

[0284] [Corrected 13.12.2024 according to Rule 91] The working fluid disclosed in the embodiment of the present application can have a smaller impedance (flow resistance) and a larger flow rate when applied to the liquid cooling module, thereby having a stronger heat exchange capacity and an equivalent thermal conductivity. Specifically, refer to Figure 7, which is a relationship curve between the flow rate Q and the impedance P (unit is Pa) of the liquid cooling module. Among them, curve C is the pressure-flow curve of the pump in the liquid cooling system, that is, the PQ curve. Curve A is the impedance-flow PQ data of the working fluid disclosed in the embodiment of the present application (the first medium is water), and the intersection with curve C is the impedance-flow value in actual application, the working point impedance is ~37000KPa, and the flow rate is ~1.8ml / min; curve B is the impedance-flow PQ data of the working fluid (fluorinated liquid plus quicksand oil), and the intersection with curve C is the impedance-flow value in actual application, the working point impedance is ~60000KPa, and the flow rate is ~1.2ml / min. It can be seen that for the same pump and the same liquid cooling module, the mixed working fluid disclosed in the embodiment of the present application has smaller viscosity and impedance, higher flow rate and flow velocity, and thus has a lower temperature difference and a higher equivalent thermal conductivity.

[0285] [Corrected 13.12.2024 according to Rule 91] The following is an explanation based on specific experimental results. The specific experimental results can be found in Table 1:
