Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example

[0032] Reference Figures 1 to 3, which is the first embodiment of the present invention, provides a high-efficiency heat pipe array radiator, which includes a main body mechanism 100 and a fixing mechanism 200, wherein the main body mechanism 100 includes a heated base 101, a heat pipe 102, a circulation pump 103, a circulation pipe 104, a heat dissipation box 105 and heat dissipation fins 106, one end of the heat pipe 102 extends inside the heated base 101, and the other end thereof is provided with heat dissipation fins 106 in an array on the side wall; the circulation pump 103 is arranged on the back side wall of the heated base 101, and is connected to the heat dissipation box 105 through the circulation pipe 104; the heat dissipation fins 106 are arranged on the side wall of the heat dissipation box 105, a heat dissipation fan 107 is also arranged on the top of the heat dissipation fins 106, and an installation frame 108 is arranged outside the heat dissipation fan 107.

[0033] The heat pipes 102 are arranged in a plurality of arrays on the circumferential sidewall of the heated base 101 , and one end away from the heated base 101 spirally extends upward along the outer wall of the heat dissipation box 104 ; any heat dissipation fins 106 are connected to the walls of the plurality of heat pipes 102 .

[0034] The circulation pipe 104 includes a liquid inlet pipe 104a and a liquid discharge pipe 104b. One end of the liquid inlet pipe 104a is connected to the liquid inlet end of the circulation pump 103, and the other end is connected to the liquid outlet of the heat dissipation box 105. One end of the liquid discharge pipe 104b is connected to the liquid discharge end of the circulation pump 103, and the other end is connected to the liquid inlet of the heat dissipation box 105. The heat dissipation box 105 is filled with a cooling medium.

[0035] The heat dissipation fins 106 are parallel to each other and maintain an integrated structure; the heat dissipation fins 106 extend on the inner cavity and outer side wall of the heat dissipation box 105; and fixing holes 108a are provided at the four corners of the installation frame 108.

[0036] Among them, the heated base 101 is used to quickly transfer the heat generated by the heating element, and can be made of a brass base in the prior art; the heat pipe 102 and the circulating pump 103 are in direct contact with the heated base 101, and are used to quickly transfer the heat absorbed in the heated base 101. One end of the heat pipe 102 is an evaporation end, which is embedded in the heated base 101, and the other end is a condensation end, which is connected to the heat dissipation fins 106, and heat is dissipated through the heat dissipation fins 106; the circulating pump 103, the circulating pipe 104 and the heat dissipation box 105 circulate the cooling medium, and the cooling medium uses a liquid with a large specific heat capacity, which can absorb and temporarily store more heat, thereby quickly reducing the temperature of the heated base 101.

[0037] The heat pipes 102 are distributed in multiple groups, which is conducive to the dispersion of heat and the heat dissipation. Similarly, the same heat pipe 102 is connected to multiple heat dissipation fins 106 to improve the heat dissipation efficiency. In the water cooling heat dissipation part, the heat dissipation box 105 and the heat dissipation fins 106 are connected in an integrated manner. The heat dissipation fins 106 are in contact with the cooling medium inside the heat dissipation box 105 and exchange heat with the cooling medium. The part extending outside the heat dissipation box 105 can help the heat dissipation box 105 to dissipate heat quickly. This combination also improves the heat dissipation effect of water cooling.

[0038] Furthermore, the cooling fan 107 is used to accelerate the heat dissipation of the heat dissipation box 105 and the heat dissipation fins 106, thereby improving the cooling efficiency of the radiator as a whole. The cooling fan 107 is fixed by a mounting frame 108. It should be noted that the fan can be installed at other positions of the radiator body. In this embodiment, it is shown as being installed at the top of the heat dissipation fins 106.

[0039] In summary, the radiator structure shown in this embodiment combines the existing air-cooled heat dissipation and water-cooled heat dissipation structures, and has the characteristics of fast heat exchange of air-cooled heat exchange and large heat exchange capacity of water-cooled heat exchange. Through the ingenious combination of the two structures, the heat dissipation efficiency of the radiator is greatly improved. Example

[0040] Reference Figures 4 to 7 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that: a new type of fixing structure is proposed, which greatly simplifies the installation and disassembly process of the radiator body structure in Example 1 and reduces the difficulty of maintenance.

[0041] Specifically, the fixing mechanism 200 includes a supporting base 201, a first connecting column 202, a second connecting column 203 and a connecting piece 204. The supporting base 201 is arranged below the heated base 101. The first connecting column 202 and the second connecting column 203 are respectively matched with the connecting piece 204 and connected between the installation frame 108 and the supporting base 201.

[0042] A receiving groove 201 a is formed in the middle of the receiving base 201 , and through holes 201 b corresponding to the positions of the fixing holes 108 a are formed at the four side walls of the receiving base 201 .

[0043] Among them, the supporting base 201 is used for the installation and support of the entire radiator structure, which is usually fixed on the main board that needs to be cooled, and the components that need to be cooled are located in the accommodating groove 201a; the connecting column structure composed of the first connecting column 202, the second connecting column 203 and the connecting member 204 is supported between the supporting base 201 and the installation frame 108.

[0044] Furthermore, the first connecting column 202 and the second connecting column 203 have the same structure, and a limiting head X is provided at one end thereof, and a first limiting ring groove H is provided on the side wall of the other end thereof, and a plurality of groups of the first limiting ring grooves H are evenly provided. It should be noted that the lengths of the two are different, that is, there is a difference in the length of the column except for the limiting head X part.

[0045] The connecting piece 204 is used for the combined connection of two connecting columns, and the whole includes a column tube 204a, a limiting steel ball 204b, a first sleeve 204c, a second sleeve 204d and a return spring 204e. The limiting steel ball 204b is arranged in a limiting groove 204a-1 provided in the side wall of the column tube 204a. The first sleeve 204c and the second sleeve 204d are connected by the return spring 204e and are sleeved on the outer wall of the column tube 204a.

[0046] Among them, the outer wall of the column tube 204a is provided with an annular groove 204a-2, and a retaining ring 204a-3 is formed at both ends of its column body. The first sleeve 204c, the second sleeve 204d and the return spring 204e are located in the annular groove 204a-2 interval, and the return spring 204e is at an initial length; that is, the first sleeve 204c, the second sleeve 204d and the return spring 204e are sleeved on the annular groove 204a-2 part of the column tube 204a, and the lengths of the three are equal to the axial length of the annular groove 204a-2.

[0047] There are several groups of equally spaced arrays of limiting grooves 204a-1, which vertically penetrate the side walls of the column tube 204a. The groove body is capsule-shaped, and its axial length is greater than the diameter of the limiting steel ball 204b. The spherical side walls of the limiting steel ball 204b can partially extend out of the two end grooves of the limiting groove 204a-1 and be embedded in the first limiting ring groove H or the second limiting ring groove C.

[0048] A second limiting ring groove C is formed on the inner side walls of the first sleeve 204c and the second sleeve 204d.

[0049] In the side wall of the column tube 204a, a large number of limiting grooves 204a-1 are opened perpendicular to the side wall. The limiting grooves 204a-1 are capsule-shaped as a whole, and their axial ends penetrate the side wall of the column tube 204a and maintain the internal and external connection of the column tube 204a; the limiting steel ball 204b can move in the limiting groove 204a-1, so that part of the ball can extend to the notch of the limiting groove 204a-1, and can only extend to the notch at one end, and will not roll out of the limiting groove 204a-1, that is, the axial length of the limiting groove 204a-1 is greater than the diameter of the limiting steel ball 204b, and less than the diameter of the limiting steel ball 204b plus the length of the radius.

[0050] When the ball of the limiting steel ball 204b extends out of the two end notches of the limiting groove 204a-1, it can be just engaged in the first limiting ring groove H or the second limiting ring groove C.

[0051] When the connecting member 204 is in the initial state, the return spring 204e is at an initial length, and the second limiting ring grooves C in the first sleeve 204c and the second sleeve 204d are both misaligned with the notches of the limiting groove 204a-1.

[0052] Combined with Figures 1 to 7 As shown in , the implementation method of this embodiment is: taking the fixing mechanism 200 to fix the main body mechanism as an example, before installation, the supporting base 201 is placed on the main board that needs heat dissipation, and the electronic components that need heat dissipation are located in the receiving groove 201a in the middle of the base, and the through holes 201b at the four corners of the supporting base 201 are kept corresponding to the positioning and mounting holes on the main board, and then the assembly process is carried out.

[0053] Insert the first connecting column 202 from the bottom of the positioning and mounting hole on the main plate into the through hole 201b, and point one end of the assembled connecting piece 204 toward the plug-in end of the first connecting column 202; then pull the first sleeve 204c, compress the reset spring 204e to make it close to the second sleeve 204d; so that the second limiting ring groove C in the first sleeve 204c is aligned with the groove of the limiting groove 204a-1, so that the limiting steel ball 204b can move freely in the limiting groove 204a-1 and can be embedded in the second limiting ring groove C. At this time, the end of the first connecting column 202 is inserted into the inner cavity of the column tube 204a and can move freely; when inserted to the target position, that is, when the first limiting ring groove H on the side wall of the first connecting column 202 is aligned with the notch of the limiting groove 204a-1, the first sleeve 204c is released again, and under the pulling force of the reset spring 204e, the second limiting ring groove C of the first sleeve 204c will be dislocated with the notch of the limiting groove 204a-1 again, and during the dislocation process, its side wall pushes the limiting steel ball 204b to move to the other end of the limiting groove 204a-1, and stably embeds in the first limiting ring groove H. At this time, the first connecting column 202 and the connecting member 204 are stably connected; preferably, the bottom side wall of the column tube 204a is kept in contact with the top surface of the receiving base 201, so as to maintain the stability of the supporting structure formed by the connecting member 204 and the first connecting column 202.

[0054] After the installation of the supporting base 201 is completed, the main body 100 is placed, and then the second connecting column 203 is passed through the fixing hole 108a, and assembled through the same process as the first connecting column 202, which will not be repeated. It should be noted that different support lengths can be formed by plugging and combining the two connecting columns and the column tube 204a. For the installation of the connecting column, only the sleeve needs to be operated, which avoids the cumbersome operation caused by the existing screw and nut combination, and has the characteristics of simple operation, firm structure, and easy maintenance.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
