[0002] The radiator combined with water cooling and heat plate has been widely used in various fields due to its good heat dissipation effect.

[0036] As Figures 2 to 10 shown, an enhanced three -dimensional heat -evening radiator, including base 1;

[0037] The base 1 is provided with a plurality of flat-parallel heat plates 2, each of which has a hollow first accommodating cavity 21, and the base 1 is provided with a second accommodating cavity 10, each of the first accommodating cavities 21 is communicated with the second accommodating cavity 10 and forms a steam cavity together, the steam cavity is used for accommodating steam; the middle part of the heat plate 2 is upwardly protruded so that the vertical section of the middle part of the heat plate 2 is in the shape of Π, at least one side of the bottom end of the heat plate 2 is horizontally outwardly extended to form a bottom edge 22, and at least one side of the heat plate 2 is horizontally outwardly extended to form a plurality of spaced-apart heat dissipation fins 23, the heat dissipation fins 23 are located above the bottom edge 22 and each of the heat dissipation fins 23 is parallel to the bottom edge 22;

[0038] The shell 3 is provided above the heat plate 2, the shell 3 is provided with a liquid inlet 31 and a liquid outlet 32, and the shell 3 is used for containing cooling liquid.

[0039] The enhanced three-dimensional heat spreading radiator mainly comprises a base 1 and a heat plate 2, the base 1 has a second accommodating cavity 10, the heat plate 2 has a first accommodating cavity 21, the first accommodating cavity 21 and the second accommodating cavity 10 jointly form a steam cavity, generally, after the base 1 and the heat plate 2 are assembled, the steam cavity is in a vacuum state and is filled with steam generated by liquid working medium, heat is transferred through evaporation and condensation of the liquid working medium; the upper part of the heat plate 2 is further provided with a shell 3, the shell 3 contains cooling liquid (such as water), the cooling liquid enters the shell 3 through the liquid inlet 31, flows through the heat dissipation fins 23 and then flows out of the shell 3 through the liquid outlet 32 to take away heat, and the enhanced three-dimensional heat spreading radiator has good heat dissipation effect.

[0040] Particularly, the base 1 is provided with a plurality of flat-parallel heat plates 2, in actual installation, three independent heat plates 2 can be spliced to form a complete 3DVC structure, the vertical section of the middle part of each heat plate 2 is in the shape of Π (the middle part here does not refer to the center position of the heat plate 2, but refers to positions excluding the two ends of the heat plate 2), and the heat dissipation fins 23 are horizontally machined on the two sides or any side of the Π-shaped heat plate 2, and the heat dissipation fins 23 and the heat plate 2 are integrally formed. Compared with the traditional radiator structure, the heat plate 2 structure of the enhanced three-dimensional heat spreading radiator is convenient for diffusion welding of the heat plate 2 and the base 1 in the radiator, and the number of heat dissipation fins 23 can be effectively increased, so that the effective water cooling area is greatly increased and the heat dissipation efficiency is improved.

[0041] In actual machining, the heat plate 2 can be a copper block, and the heat dissipation fins 23 on the side of the heat plate 2 can be horizontally machined by a toothed machine.

[0042] Further, as shown in Figure 3 , Figure 7 and Figure 9As shown, the inner walls of the heat spreader 2 and the base 1 are respectively provided with capillary structures 5. In this scheme, the inner walls of the heat spreader 2 and the base 1 are sintered with capillary structures 5. In actual production, metal powder (e.g., copper powder) or metal mesh (e.g., copper mesh) can be applied to the heat spreader 2 or the base 1, and then sintered at high temperature after being shaped by a mold, thereby forming capillary structures 5 on the inner walls of the heat spreader 2 or the base 1, so that the capillary structures 5 are evenly distributed on the inner walls of the entire steam chamber. The liquid working fluid is usually inside the capillary structures 5, and the space inside the steam chamber is filled with steam to achieve heat dissipation of the radiator.

[0043] Furthermore, multiple positions on both sides of the heat spreader 2 extend horizontally outward to form multiple spaced heat dissipation fins 23.

[0044] like Figures 3 to 6 As shown, in the first embodiment of this solution, multiple horizontally extending heat dissipation fins 23 are provided on both sides of a single heat dissipation plate 2. In this way, the number of heat dissipation fins 23 provided on a single heat dissipation plate 2 is greater, the heat exchange area is larger, and the heat dissipation efficiency of the radiator can be further improved.

[0045] Furthermore, the length of the bottom edge 22 is greater than the length of the heat dissipation fins 23, so that the end of the bottom edge 22 extends out to form an elongated portion 24. The elongated portions 24 of any two adjacent heat dissipation plates 2 are spliced ​​together, so that there is a gap 25 between the heat dissipation fins 23 of any two adjacent heat dissipation plates 2, and a flow-blocking plate 251 is provided in the gap 25.

[0046] When heat dissipation fins 23 are provided on both sides of the heat dissipation plate 2, in order to better fit two adjacent heat dissipation plates 2, since there is a gap 25 between the heat dissipation fins 23 of each heat dissipation plate 2, if the heat dissipation fins 23 of two adjacent heat dissipation plates 2 directly abut, they may easily become misaligned after installation, causing one heat dissipation fin 23 of one heat dissipation plate 2 to insert into the heat dissipation fin 23 of the other heat dissipation plate 2, affecting heat dissipation efficiency. Therefore, in this embodiment, the length of the bottom edge 22 is set to be longer than the heat dissipation fins 23, which prevents the heat dissipation fins 23 of two adjacent heat dissipation plates 2 from directly contacting each other and avoiding the above situation. The extended portions 24 of two adjacent heat dissipation plates 2 are spliced ​​together. Specifically, one extended portion 24 is stepped downwards, and the other extended portion 24 is stepped upwards. The two fit together, and the overall thickness of the two extended portions 24 after splicing is the same as the thickness of the bottom plate.

[0047] Since the above-mentioned elongation 24 is provided in this embodiment, there will be a gap 25 between the heat dissipation fins 23 of the two heat dissipation plates 2. In order to make the coolant flow through the heat dissipation fins 23 as much as possible instead of the gap 25, this embodiment also provides a flow baffle 251 to fill the gap 25 in the middle.

[0048] Further, the base 1 is provided with a groove 11, the inside of the groove 11 is the second containing cavity 10, the groove 11 is provided with a plurality of heat-conducting support protrusions 12 arranged in an array, the heat-conducting support protrusions 12 abut the vapor chamber 2 through the capillary structure 5. In the embodiment, the base 1 is provided with the groove 11, and the groove 11 is further provided with a plurality of heat-conducting support protrusions 12 arranged in multiple rows and spaced apart, the heat-conducting support protrusions 12 are usually copper columns, which can play the roles of heat conduction and support, and the top ends of the heat-conducting support protrusions 12 on the base 1 abut the vapor chamber 2 through the capillary structure 5.

[0049] In actual production, the heat-conducting support protrusions 12 are located at two corners of the Π-shaped vapor chamber 2 to contact the bottom plates on both sides of the vapor chamber 2, thereby achieving better heat conduction and support effects.

[0050] Further, the groove 11 is provided with a plurality of support portions 13 arranged in a spaced-apart manner to divide the groove 11 into multiple compartments 111, and a plurality of liquid passing holes 131 are formed in the support portions 13.

[0051] The capillary structures 5 on the inner walls of two adjacent vapor chambers 2 are provided with an avoiding gap 51 therebetween, the avoiding gap 51 corresponds to the support portion 13 in a one-to-one manner, each support portion 13 is inserted into the corresponding avoiding gap 51, and the top end of the support portion 13 abuts the splicing position of any two adjacent elongated portions 24.

[0052] In the embodiment, the support portion 13 is usually integrally machined with the base 1, and the support portion 13 is a solid structure, that is, a hollow part is CNCed on the copper base 1, and the separated copper support portion 13 is left as a support for the splicing position (joint position) of the two elongated portions 24, which can ensure the stability of the splicing between the adjacent vapor chambers 2. In order to make the steam flow between the compartments 111, some liquid passing holes 131 are also formed in the support portion 13 to allow the steam and liquid to pass through.

[0053] Further, a plurality of positions on the left side or the right side of the vapor chamber 2 horizontally extend outward to form a plurality of heat dissipation fins 23 arranged in a spaced-apart manner, in any two adjacent vapor chambers 2, the heat dissipation fins 23 of the front vapor chamber 2 abut the side of the rear vapor chamber 2 on which the heat dissipation fins 23 are not arranged, the side of the vapor chamber 2 on which the heat dissipation fins 23 are not arranged abuts the heat dissipation fins 23, and the vapor chamber 2 is further provided with a cover plate 4 between the base 1.

[0054] As Figures 7 to 10As shown, in the second embodiment of the present scheme, a plurality of heat dissipation fins 23 are formed on the left or right side of the heat plate 2. The heat plate 2 of this structure is not provided with the gap 25, and directly abuts the heat dissipation fin 23 of the rear heat plate 2 from the side of the front heat plate 2 without the heat dissipation fin 23. The overall space utilization is higher, and the heat dissipation fin 23 is only processed on one side of the heat plate 2, so the processing process is simpler and the manufacturing difficulty is lower. At the same time, it also has good heat dissipation effect. A cover plate 4 is further arranged between the heat plate 2 and the base 1, which can improve the sealing performance and structural strength of the bottom end of the heat plate 2. Generally, the cover plate 4 is only arranged at the position where the heat plate 2 and the base 1 or other internal components are in contact. The material of the cover plate 4 can be the same as that of the heat plate 2 / heat dissipation fin 23.

[0055] Further, the base 1 is provided with a groove 11, and a plurality of heat-conducting support protrusions 12 are arranged in the groove 11 in an array. The heat-conducting support protrusions 12 successively abut the cover plate 4 through the capillary structure 5.

[0056] In the present embodiment, the lower end of the heat plate 2 is provided with the cover plate 4, so that the top end of the heat-conducting support protrusion 12 abuts the cover plate 4 through the capillary structure 5. The heat-conducting support protrusion 12 also plays a role in heat conduction and support. In actual production, the heat-conducting support protrusion 12 can be located in the middle or at the two corners of the cover plate 4.

[0057] Further, the capillary structure 5 of the inner wall of the base 1 has a plurality of sleeves 52, and each sleeve 52 is sleeved on the outer wall of the corresponding heat-conducting support protrusion 12. The top end of the sleeve 52 abuts the capillary structure 5 of the inner wall of the heat plate 2.

[0058] In the present embodiment, the outer wall of the heat-conducting support protrusion 12 is further sleeved with the sleeve 52 of the capillary structure 5, which can guide the liquid working medium. The sleeve 52 in the capillary structure 5 is separately sintered in the mold and installed outside the heat-conducting support protrusion 12, and the other capillary structures 5 except the sleeve 52 are sintered on the surface of the base 1.

[0059] Further, any two adjacent heat plates 2 are fixed by diffusion welding, the base 1 and the heat plate 2 are fixed by diffusion welding, and the shell 3 and the heat plate 2 are fixed by brazing. The adjacent heat plates 2, the base 1 and the heat plate 2 are preferably fixed by diffusion welding, and the shell 3 and the heat plate 2 are preferably fixed by brazing.

[0060] Of course, in other embodiments, the heat plate 2 and the heat plate 2, the base 1 and the heat plate 2, and the shell 3 and the heat plate 2 can also adopt other existing fixing methods, as long as they can ensure the stability and sealing performance of the heat sink structure.

[0061] Further, the bottom end of the base 1 is further provided with a downward protruding clamping portion 14, which is used for fixing the enhanced three-dimensional uniform heating radiator on a device to be cooled. A slot matching the shape of the clamping portion 14 is usually arranged on the device to be cooled, and the clamping portion 14 is clamped into the slot, so that the enhanced three-dimensional uniform heating radiator can be directly fixed on the device to be cooled to play a role of heat dissipation.

[0062] The enhanced three-dimensional uniform heating radiator is processed as follows: first, the base 1 with the heat-conducting support protrusion 12 is processed; then, a layer of capillary structure 5 is sintered on the base 1; at least one side of the single uniform heating plate 2 is processed to have the heat dissipation fin 23; a plurality of uniform heating plates 2 with the heat dissipation fin 23 are diffusion welded into one uniform heating plate 2; a layer of capillary structure 5 is sintered on the uniform heating plate 2; the sleeve 52 of the capillary structure 5 is placed on the heat-conducting support protrusion 12 to connect the capillary structure 5 of the bottom plate and the capillary structure 5 of the uniform heating plate 2; the base 1 and the uniform heating plate 2 are diffusion welded into one whole, and the interiors of the two together form a vacuum vapor cavity, liquid working medium is injected into the vapor cavity, and during use, the liquid working medium is located in the capillary structure 5 → vacuumizing → sealing the inlet of the injected liquid working medium; finally, the shell 3 is brazed above the uniform heating plate 2, so that the cooling liquid flows into the shell 3 from the liquid inlet 31 at one end, and then flows out from the liquid outlet 32 at the other end.
