[0043] The heat sink manufacturing method according to the first embodiment of the present invention is described in detail below.

[0044] refer to Figure 1 According to the heat sink manufacturing method of the first embodiment of the present invention, the method includes but is not limited to the following steps:

[0045] Step S100, welding a plurality of heat dissipation copper tubes 100 to the base body 200 in sequence to form a heat sink, wherein the area where the heat dissipation copper tubes 100 and the base body 200 are welded together forms a welding area 300;

[0046] Step S200 , performing magnetic grinding on the welding area 300 to enhance the hardness of the welding area 300 .

[0047] It should be noted that the reference Figure 6The radiator includes a base body 200 and a plurality of heat dissipation copper tubes 100. The plurality of heat dissipation copper tubes 100 are spaced apart along a first direction. The heat dissipation is extended along a second direction. The base body 200 is located at a common end of the plurality of heat dissipation copper tubes 100 in the second direction, and one end of the heat dissipation copper tubes 100 in the second direction is welded to the base body 200. The area where the heat dissipation copper tubes 100 are welded to the base body 200 forms a welding area 300.

[0048] It should be noted that in the process of welding the heat dissipating copper tube 100 to the base body 200, the temperature of the welding area 300 can reach 600°C to 1200°C. At this temperature, the structure of the welding area 300 will soften, thereby making the overall structural strength of the welding area 300 low. Furthermore, during the use of the radiator, due to the low structural strength of the welding area 300, the heat dissipating copper tube 100 and the base body 200 are prone to breakage.

[0049] In the manufacturing method of the heat dissipation copper tube 100 of the present invention, a plurality of heat dissipation copper tubes 100 are first welded to the base body 200 in sequence to form a heat sink, wherein the area where the heat dissipation copper tube 100 and the base body 200 are welded forms a welding area 300, and then the welding area 300 is magnetically ground to enhance the hardness of the welding area 300. In the process of manufacturing a heat sink using the heat dissipation copper tube 100 of the present invention, after the heat dissipation copper tube 100 is welded to the base body 200, the welding area 300 is magnetically ground, so that the welding area 300 of the heat sink manufactured using the heat dissipation copper tube manufacturing method of the present invention can have a higher hardness, so as to reduce the probability of subsequent fracture between the heat dissipation copper tube 100 and the base body 200, so that the manufactured heat sink can have a higher structural strength.

[0050] In some embodiments of the present invention, reference Figure 2 In step S200, the following steps are included but are not limited to:

[0051] Step S210, burying the welding area 300 in abrasive;

[0052] Step S220 , vibrating the abrasive so that the abrasive continuously impacts the welding area 300 .

[0053] It can be understood that by burying the welding area 300 in the abrasive, the welding area 300 can be fully in contact with the abrasive. When the abrasive is subsequently vibrated, each part of the welding area 300 can be evenly impacted by the abrasive, so that after the welding area 300 is magnetically ground, the hardness of each area of ​​the welding area 300 can be close to the same, and the internal stress of the welding area 300 after magnetic grinding can be reduced.

[0054] In some embodiments of the present invention, reference Figure 3In step S210, the following steps are included but are not limited to:

[0055] Step S211, burying the heat sink in the abrasive;

[0056] Step S212 , pre-vibrating the abrasive material so that the abrasive material can fully fill each gap of the heat sink and fully wrap each welding area 300 .

[0057] It should be noted that if the radiator is directly buried in the abrasive, due to the small gap between two adjacent heat dissipation copper tubes 100, it is difficult for the abrasive to completely fill the gap between the two adjacent heat dissipation copper tubes 100, making it difficult for the area of ​​the welding zone 300 close to the gap to fully contact with the abrasive. In this case, if the abrasive is directly vibrated to grind the welding zone 300, the grinding effect of the area of ​​the welding zone 300 close to the gap will be poor, thereby affecting the overall strength of the welding zone 300 after magnetic grinding.

[0058] In the heat sink manufacturing method of the present embodiment, after the heat sink is buried in the abrasive, the abrasive is pre-vibrated so that the abrasive can be fully filled into the various gaps of the heat sink, so that the area of ​​the welding zone 300 close to the gap can also be fully contacted with the abrasive, and then the subsequent vibration of the abrasive can make the area of ​​the welding zone 300 close to the gap can also be fully ground, thereby improving the overall strength of the welding zone 300 after magnetic grinding.

[0059] In some embodiments of the present invention, the abrasive is one or more combinations of steel needles and steel balls.

[0060] In some embodiments of the present invention, reference Figure 4 In step S100, the following steps are included but not limited to:

[0061] Step S110, distributing a plurality of heat dissipation copper tubes 100 at intervals along a first direction, and extending the heat dissipation copper tubes 100 along a second direction, wherein a certain angle is spaced between the first direction and the second direction;

[0062] Step S120, the base body 200 is respectively abutted against one end of each heat dissipation copper tube 100 in the second direction;

[0063] Step S130 , welding the junctions between the base body 200 and each heat dissipation copper tube 100 to form a plurality of welding areas 300 .

[0064] It can be understood that, firstly, a plurality of heat dissipation copper tubes 100 are spaced and distributed along the first direction, and the heat dissipation copper tubes 100 are extended and arranged along the second direction, wherein the first direction and the second direction are spaced at a certain angle, and then, the base body 200 is respectively abutted against one end of each heat dissipation copper tube 100 in the second direction, and then, the junctions between the base body 200 and each heat dissipation copper tube 100 are respectively welded to form a plurality of welding areas 300. Thus, the plurality of heat dissipation copper tubes 100 can be welded to the base body 200 at intervals along the first direction.

[0065] In a further embodiment of the present invention, reference Figure 5 In step S130, the following steps are included but not limited to:

[0066] Step S131, preheating the base body 200 and the heat dissipation copper tube 100 to increase the temperature of the base body 200 and the heat dissipation copper tube 100;

[0067] Step S132 , sequentially soldering each heat dissipation copper tube 100 to the base body 200 .

[0068] It is understandable that before welding the heat dissipating copper tube 100 to the base body 200, the base body 200 and the heat dissipating copper tube 100 are preheated to increase the temperature of the base body 200 and the heat dissipating copper tube 100, so that when the heat dissipating copper tube 100 is subsequently welded to the base body 200, the temperature at the junction of the heat dissipating copper tube 100 and the base body 200 can reach the welding temperature faster, thereby improving the welding efficiency between the heat dissipating copper tube 100 and the base body 200.

[0069] In some embodiments of the present invention, step S131 includes but is not limited to the following steps:

[0070] Step S131a, heating the environment where the base body 200 and the heat dissipation copper tube 100 are located, so that the temperature of the base body 200 and the heat dissipation copper tube 100 is heated to 600° C. to 1000° C.

[0071] It is understandable that the melting point of copper is 1084.6°C. By heating the base 200 and the heat dissipating copper tube 100 to 600°C to 1000°C, the base 200 and the heat dissipating copper tube 100 can maintain their solid state while their own temperature can be closer to the melting point of copper.

[0072] refer to Figure 6 The radiator provided according to the second aspect of the embodiment of the present invention is manufactured by the radiator manufacturing method of the first aspect of the embodiment of the present invention; the radiator includes a base body 200 and a plurality of heat dissipation copper tubes 100, the plurality of heat dissipation copper tubes 100 are welded to the base body 200, and the area where the heat dissipation copper tubes 100 and the base body 200 are welded forms a welding area 300.

[0073] In a further embodiment of the present invention, reference Figure 6 , multiple heat dissipation copper tubes 100 are distributed at intervals along the first direction, and the heat dissipation copper tubes 100 are extended along the second direction, and the second direction is spaced a certain angle from the first direction; the radiator includes two base bodies 200, the two base bodies 200 are distributed along the second direction, and the heat dissipation copper tubes 100 are respectively welded to the two base bodies 200 at opposite ends in the second direction.

[0074] It can be understood that by providing two base bodies 200 , the overall structure of the radiator can be made more stable.

[0075] The radiator production line provided in accordance with the third aspect embodiment of the present invention is used to implement the radiator manufacturing method as in the first aspect embodiment of the present invention; the radiator production line includes a welding module and a grinding module, the welding module is used to weld multiple heat dissipation copper tubes 100 to a base body 200 to form a radiator, wherein the area where the heat dissipation copper tubes 100 and the base body 200 are welded forms a welding area 300, and the grinding module is used to perform magnetic grinding on the welding area 300 to enhance the hardness of the welding area 300.
