Description

Technical Field

[0001] The invention belongs to the field of digital accessories, and in particular relates to a temperature averaging board and a method for manufacturing the temperature averaging board. Background Art

[0002] In recent years, electronic components have increasingly shown a trend of miniaturization and high power consumption. How to solve the problem of performance degradation of electronic components due to high heat generation has attracted widespread attention. Among them, heat pipe two-phase cooling equipment has become an efficient heat transfer device due to the large thermal conductivity generated by phase change. The temperature plate is composed of a closed container, a capillary structure and a working fluid. In order to ensure that the temperature plate has efficient heat exchange performance, the outer shell is usually made of a material with high thermal conductivity, and a liquid wick is attached around the inner wall. In order to meet the pressure resistance requirements, some temperature plates are designed with solid columns, sintered columns or liquid wicks attached to the outer surface of the solid column to form a sintered ring. When heat is applied to the bottom of the temperature plate, the liquid evaporates as the heat increases, and the steam rises to the top of the container to condense, relying on the liquid wick to return to the evaporation surface to form a cycle. Compared with traditional heat pipes, the axial dimension of the temperature plate is greatly shortened, which reduces the flow resistance loss of the working fluid and the axial thermal resistance. At the same time, the radial dimension has increased, which significantly increases the area of ​​the evaporation surface and the condensation surface, and has a smaller diffusion thermal resistance and higher temperature uniformity. This special structure improves the heat dissipation capacity of the temperature vapor chamber, increases the reliability of the electronic equipment being cooled, and provides a new solution to the problem of temperature uniformity under high heat flux in a limited space.

[0003] In the prior art, the water collecting and guiding components of the temperature equalizing plate are directly formed by etching or stamping.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0033] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0035] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] Embodiment 1, as Figure 1-Figure 2 As shown, the temperature plate includes a condensing plate body 1 and an evaporating plate body 2 whose edges are fixed to each other, and the condensing plate body 1 and the evaporating plate body 2 are formed inside as shown in FIG. Figure 3In the cavity S shown, the evaporation plate 2 needs to be in fixed contact with the heat source, and the heat generated by the heat source is transferred by the medium in the temperature equalizing plate, while the heat is condensed and dissipated on the condensation plate 1.

[0037] Specifically, Figure 3 As shown, a plurality of water collecting and guiding members 3 extending toward the evaporation plate body 2 and having at least one water collecting and guiding groove 30 are provided in the cavity S, the water collecting and guiding members 3 are fixed on the substrate 5, the substrate 5 is fixed on the inner surface of the condensation plate body 1, and the hydrophobic matrix is ​​at least partially provided on a surface of the substrate 5 away from the condensation plate body 1. Specifically, the water collecting and guiding members 3 are fixed to the substrate 5 by bonding / 3D printing / glue curing, etc., and the substrate 5 is, for example, any one of a mesh plate and a non-mesh plate. For example, the hydrophobic matrix of the present application has bonding and hydrophobic properties, and the hydrophobic matrix can fix the water collecting and guiding members 3 to the corresponding mesh of the substrate 5. The hydrophobic matrix is, for example, viscous, sheet-like, and the like.

[0038] In this embodiment, the water collecting and guiding member 3 has a spherical convex surface 31, and a plurality of water collecting and guiding grooves 30 are respectively distributed along the long-distance condensation direction Y on the spherical convex surface 31, such as Figure 6-Figure 7 As shown, a plurality of water collecting ribs 310 are provided on the spherical convex surface 31, which are distributed along the long-distance condensation direction Y, and the transverse cross section of the water collecting ribs 310 is triangular or trapezoidal. In this embodiment, the cross section of the water collecting ribs 310 is designed to be triangular, and two adjacent water collecting ribs 310 form a water collecting and diverting groove 30; the water collecting and diverting groove 30 is distributed along the long-distance condensation direction Y of the cavity S and diverts the collected condensate to the evaporation end of the evaporation plate body 2. In addition, the groove depths of the water collecting and diverting grooves 30 on each water collecting and diverting member 3 are equal or unequal. In this embodiment, the height and spacing of the water collecting ribs 310 are studied and adjusted to the most efficient height and spacing to ensure that the condensate can flow smoothly. When the condensate is formed on the water collecting ribs 310, the larger condensate water droplets will enter the water collecting and diverting groove 30 between the two water collecting ribs 310, and it will flow along the water collecting and diverting groove 30, and finally converge to the diversion area to complete the effective collection of the condensate.

[0039] The water collection and diversion component 3 in this scheme has a bionic structure, and its design inspiration comes from the super hydrophobic and hydrophilic properties of the back of the Namib Desert beetle. The water collection and diversion grooves 30 and the spherical convex surface 31 on the component imitate the "point-like protrusions" and "ridge-like protrusions" on the back of the beetle, and through the combination of strong hydrophilic areas and hydrophobic areas, efficient water collection and transmission are achieved. Water flows along the water collection and diversion grooves 30 by adsorption, aggregation and sliding, and is finally guided into the transmission channel to complete the water collection process. This structure improves the collection efficiency of liquid and can effectively simulate the water collection mechanism on the back of the beetle in nature.

[0040] At the same time, a hydrophilic matrix is ​​provided on the surface of the water collecting and guiding member 3, which can significantly improve the water collecting efficiency of the condensate and ensure that the condensate can flow smoothly along the water collecting and guiding groove 30. At the same time, a hydrophobic matrix or an inner hydrophilic matrix is ​​also provided on the inner surface of the condensation plate body 1. The design of this hydrophilic and hydrophobic layer can be selected to be hydrophobic or hydrophilic according to the specific working conditions to optimize the distribution and flow of the condensate. In this embodiment, the inner surface of the condensation plate body 1 is designed as a hydrophobic matrix to optimize the flow efficiency of the condensate.

[0041] Specifically, the width of the notch of the water collection and diversion groove 30 is greater than the bottom width of the water collection and diversion groove 30. This trapezoidal groove design can enhance the flow stability and water collection efficiency of the condensate, that is, the water is adsorbed by the surface of the strongly hydrophilic water collection rib 310, and gradually grows to form a layer of water film. At the same time, the surface attraction of the water film will further adsorb the water. When the water film spreads between the water collection rib 310 and the bottom water collection and diversion groove 30, it will be anchored on the surface due to the small three-phase contact line. The water film increases in the thickness direction and gradually slides down along the transmission channel.

[0042] The wider slot design makes it easier for the condensate to flow into the water collecting and diverting groove 30 from the tip of the water collecting rib 310, thereby improving the condensate collection capacity; while the narrower slot bottom design helps to reduce the flow resistance, ensuring that the condensate can flow smoothly along the slot and finally converge to the designated diversion area. The slot wall and the slot bottom of the water collecting and diverting groove 30 are respectively provided with a hydrophilic matrix.

[0043] In this embodiment, during the flow of the condensate, the hydrophilic matrix on the surface of the water collecting and guiding member 3 works in cooperation with the hydrophobic layer on the inner surface of the condensation plate body 1. After the condensate is formed on the surface of the water collecting and guiding member 3, it will flow rapidly along the hydrophobic layer in the condensation plate body 1 due to the effect of surface tension, and finally converge to the designated guiding area, completing the efficient collection of the condensate.

[0044] The temperature equalizing plate has a plurality of water collecting and guiding components 3 distributed in an array, and these water collecting and guiding components 3 are fixed to the inner surface of the condensing plate body 1 by using a hydrophobic matrix or an inner hydrophilic matrix as a binder. The hydrophobic matrix or the inner hydrophilic matrix not only plays a role in surface treatment, but also ensures a firm bond between the water collecting and guiding components 3 and the condensing plate body 1 through its special physical and chemical properties, avoiding poor contact or falling off caused by thermal expansion and contraction or other external factors.

[0045] This design enables the water collecting and guiding member 3 to be firmly installed on the inner surface of the condensation plate body 1, and the bonding performance of the hydrophobic matrix or the inner hydrophilic matrix further enhances the durability and reliability of the entire condensation system. During the condensation process, the inner surface of the condensation plate body 1 cooperates with the water collecting and guiding member 3 through the characteristics of the hydrophobic matrix or the inner hydrophilic matrix to optimize the distribution and flow path of the condensate, ensuring that the condensate can be collected efficiently and stably.

[0046] The array distribution design of the water collecting and guiding components 3 can fully cover the inner surface of the condensing plate body 1, ensuring that the condensate generated at any position can be quickly collected in the water collecting and guiding components 3, thereby avoiding the retention or uneven distribution of the condensate. Figure 4-Figure 5 As shown, in this embodiment, the distribution density of the water collecting and guiding components 3 gradually increases from the heat source area S1 to the condensation area S2. This design further optimizes the flow path of the condensate, reduces energy loss, and improves the overall condensation efficiency.

[0047] In addition, in order to ensure that the thermal cycle in the temperature equalizing plate is stable and complete, a liquid absorbent core 4 is also provided in the above-mentioned cavity S, and the water collecting and guiding member 3 contacts or is separated from the liquid absorbent core 4. The liquid absorbent core 4 absorbs the large water droplets after condensation, and then transports the condensed liquid to the heat source area S1 through capillary action, completing the thermal cycle movement of the condensed liquid.

[0048] like Figure 8 As shown, this solution designs three shapes of water-collecting ribs 310, while taking into account the difference in the improvement of water-collecting performance between the water-collecting ribs 310 and the water-collecting diversion grooves 30 of the same shape. Therefore, three water-collecting diversion grooves 30 of the same shape as above are also designed. The difference is that the design of the water-collecting ribs 310 is more conducive to the capture of mist and accelerates the condensation of mist into small water droplets. Compared with the irregular grooves formed by the water-collecting ribs 310, the design of the water-collecting diversion grooves 30 of the same shape makes the water droplets condense and gather to form a water film faster, which reduces the friction of water flow and accelerates the transportation of water. Fig. 9 As shown, after performing hydrophilic / hydrophobic treatment on the cavity S, performing surface hydrophilic group and hydrophilic structure treatment on the water collecting and guiding member 3 and performing hydrophobic treatment on the inner surface of the condensation plate body 1, it is found that the water collecting performance is significantly improved.

[0049] Embodiment 2: The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference lies in that, for the temperature averaging plate of the above-mentioned Embodiment 1, this embodiment describes a method for manufacturing the temperature averaging plate.

[0050] The manufacturing method comprises the following steps:

[0051] S1. Prepare a condensation plate body 1, an evaporation plate body 2 and a plurality of water collecting and guiding components 3 each having a water collecting and guiding groove 30, and set a hydrophobic layer on the inner surface of the condensation plate body 1, and set an inner hydrophilic matrix or a hydrophobic matrix on the surface of the water collecting and guiding component 3; the condensation plate body 1 is made of regularly arranged micropores by stamping, etching or laser, and the water collecting and guiding component 3 corresponds to the micropores one by one and the two are fixed, and the hole spacing is adjusted according to specific needs to ensure the uniform heat exchange efficiency of the condensation plate body.

[0052] S2, several water collecting and guiding components 3 in S1 are fixed to the condensing plate body 1 in an interval manner, and the interval distance between the water collecting and guiding components is optimized and designed according to the flow rate and distribution uniformity of the condensate. And the water collecting and guiding grooves 30 are distributed along the long-distance condensation direction Y of the condensing plate body 1;

[0053] S3, the edges of the condensing plate body 1 and the evaporating plate body 2 in S2 are fixed to each other and a cavity S is formed inside, and the water collecting and guiding member 3 is in the cavity S and extends to the side of the evaporating plate body 2; the edges of the condensing plate body 1 and the evaporating plate body 2 can be fixed by welding, gluing or mechanical fastening, and sealing material is applied at the joints to prevent leakage of the cooling liquid.

[0054] S4, inject cooling liquid into the cavity S. The cooling liquid is usually a liquid with good thermal conductivity and chemical stability, such as water, ethanol or special coolant. The total amount of cooling liquid injected is less than the total volume of the cavity S, so as to leave a certain space to accommodate the thermal expansion of the cooling liquid. After the injection is completed, the injection port needs to be sealed to ensure that the cooling liquid does not leak, that is, the temperature equalization board is obtained.

[0055] In S2 , a plurality of water collecting and guiding components 3 in S1 are fixed to a base plate 5 in an array manner, and the base plate 5 is fixed to the inner surface of the condensation plate body 1 .

[0056] The substrate 5 is a grid plate or a flat plate, the flat plate is punched or etched or lasered to form regularly arranged micropores, and the water collecting and diverting components 3 correspond to the micropores one by one and the two are fixed. Or the water collecting and diverting components 3 correspond to the mesh holes of the grid plate one by one and the two are fixed.

[0057] Embodiment 3: The structure and principle of this embodiment are basically the same as those of Embodiment 1. The different structure is that, with respect to the temperature equalizing plate of the above-mentioned Embodiment 1, this embodiment describes the composition of the hydrophilic and hydrophobic matrix of the water collecting and guiding component of the temperature equalizing plate.

[0058] In this embodiment, the groove wall and groove bottom of the water collecting and diverting groove 30 have the following different matrix composition modes:

[0059] The first method is to provide the hydrophilic matrix on the groove wall and the groove bottom of the water collecting and diverting groove 30 respectively; through the hydrophilic design of the entire groove, the capillary drive can be strengthened, and a continuous capillary network can be formed with the liquid wick, which significantly improves the reflux rate of the condensate to the evaporation end;

[0060] The second method is to provide the hydrophobic matrix on the groove wall and the groove bottom of the water collecting and diverting groove 30; the hydrophobic groove can form a low flow resistance steam channel, preferentially diffuse steam, promote the rapid diffusion of steam to the condensation plate body, and reduce the retention of condensate, thereby improving the condensation efficiency;

[0061] The third type: some of the water collecting and guiding grooves 30 are provided with the hydrophilic matrix, and the remaining water collecting and guiding grooves 30 are provided with the hydrophobic matrix. For example, the water collecting and guiding grooves 30 provided with the hydrophilic matrix and the water collecting and guiding grooves 30 provided with the hydrophobic matrix are arranged adjacent to each other. Specifically, the hydrophilic matrix is ​​referred to as "Q" and the hydrophobic matrix is ​​referred to as "S". Based on this, this embodiment has the following arrangements:

[0062] 1. QSQS arrangement: the hydrophilic groove Q serves as the main reflux channel, and the hydrophobic groove S serves as the auxiliary vapor diffusion path, forming an alternating and complementary fluid network;

[0063] 2.QQS arrangement: The continuous hydrophilic grooves QQ form a main channel with high capillary force, and the hydrophobic grooves S serve as secondary channels to assist steam discharge;

[0064] 3. QSS arrangement: The single hydrophilic groove Q concentrates on the high condensation area, and the double hydrophobic groove SS forms a wide steam channel.

[0065] The above three arrangement forms each have a heat exchange state with different advantages, and the advantages can be selected according to different usage conditions to achieve the best efficiency of the temperature equalizer.

[0066] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
