The manufacturing method comprises the following steps: s1, taking a water passing body and a heat dissipation cavity core as cores and putting the cores into a prefabricated radiator main body mold, wherein the heat dissipation cavity core is positioned outside the water passing body; s2, generating a heat radiation body on the water passing body through a casting process; and S3, drawing the heat dissipation cavity core out of the heat dissipation body to form the radiator main body with the heat dissipation cavity. As shown in figure 1, the water passing body comprises 2 main water pipes and at least 1 water passing pipe, the water passing pipe is connected between the 2 main water pipes, and when the heating radiator is used, hot water is injected from one main water pipe, flows to the other main water pipe through the water passing pipe and then flows out. In fig. 1, there are 2 water pipes, but it is also possible to have only one water pipe, or 3 or more water pipes. In this embodiment, the axial direction of the main water pipe is defined as the front direction and the back direction of the radiator, i.e. as shown in fig. 5, the paper direction and the back direction of the paper are the front direction and the back direction of the radiator, respectively, in fig. 5, the left side and the right side of the radiator are the left side and the right side of the radiator, respectively, and the upper side and the lower side are the face and the bottom of the radiator, respectively. And the direction of the connecting line between the 2 main water pipes is defined as the axial direction of the water passing body, namely the direction of the chain line shown in figure 1. The axial direction of the heat dissipation cavity core is the trend of the heat dissipation cavity core.

In this embodiment, the material of the water passing body includes, but is not limited to, iron, cast iron, steel, or copper. The material of the heat spreader includes, but is not limited to, aluminum, or aluminum alloy, or magnesium alloy, or copper alloy. The casting process in this embodiment includes die casting, low-pressure casting, or metal mold casting.

In this embodiment, the heat dissipation cavity core is located outside the water passing body, including a state of being located on the left side or the right side of the water passing body as shown in fig. 1, and a state of being located in the forward direction and/or the backward direction of the water passing pipe as shown in fig. 2, and fig. 2 is a top view of the water passing body and the heat dissipation cavity core after being arranged. The heat dissipation cavity core is arranged on the outer side of the water body, so that after the heat dissipation body is cast on the water body, as shown in fig. 3, the heat dissipation cavity core can be conveniently drawn out, and a heat dissipation cavity is formed inside the heat dissipation body. The heat dissipation cavity core can be drawn out from the bottom, the top or both ends. When the heat dissipation cavity core is drawn out from two ends, the heat dissipation cavity core is divided into two sections, and under the condition, the upper end and the lower end of the heat dissipation fin main body are provided with openings for core pulling. In this embodiment, in order to facilitate core pulling, the heat dissipation cavity core preferably has a draft angle of 0.2 to 3 degrees, preferably 0.5 to 1 degree.

In this embodiment, it is further preferable that the water passing body and the heat dissipation cavity core have the same direction. In this embodiment, the same trend allows deviation of a certain angle between the two, and the two are not required to be completely parallel, and complete parallelism cannot be achieved in an actual production process. In engineering practice, it is preferable that the extraction port of the radiation cavity core is located at the extraction port of the radiation cavity core only at the bottom and/or top of the radiator body, i.e., the bottom of the radiator body as shown in fig. 4. It should be noted that the extraction opening of the heat dissipation cavity core does not include a notch formed on the side wall of the heat sink at the time of casting due to the heat dissipation cavity core having a corresponding projection, such as a notch on the right side wall of the right heat dissipation cavity in fig. 4, which is formed by the projection on the heat dissipation cavity core in fig. 4. Certainly, in order to further improve the quality of the produced radiator main body, the included angle between the water body and the trend of the radiating cavity core is further preferably smaller than 10 degrees; more preferably 5 degrees or less.

Of course, the radiating cavity sub-cores can be arranged in other forms.

In this embodiment, after step S3, the method further includes: installing a radiator end cover on the opening of the heat dissipation cavity core pulling; or: and the heat radiation body is provided with a heat radiation through hole communicated to the heat radiation cavity. Because the radiator main part in this embodiment adopts casting process and the mode of loosing core to generate the heat dissipation chamber in radiator inside, must can leave the opening that is used for taking out the heat dissipation chamber core in the radiator main part, consequently, in order to make the radiator more pleasing to the eye, can also generate out the radiator end cover alone to install the radiator end cover on this opening. The end cover of the radiator can be produced by adopting a casting process or directly by adopting a stamping process. The end cover of the heating radiator can be fixedly arranged on the heating radiator main body by adopting welding, gluing, bolt fixing and other modes.

Further, a heat dissipation through hole can be opened on the radiator main body and penetrates through the radiator, so that the space inside the heat dissipation cavity is connected with the space outside the radiator, the air inside the heat dissipation cavity can form convection with the outside air, the heat dissipation efficiency is improved, and the heat dissipation effect is improved.

Example two:

the embodiment is basically the same as the first embodiment, but adopts a mode of core pulling at two ends.

As shown in fig. 8 and 9, in the present embodiment, core pulling is performed at two ends, that is, the heat dissipation cavity core is pulled out from the top and the bottom of the heating radiator respectively, so that, as shown in fig. 8 and 9, the heating radiator body of the present embodiment has openings at both the bottom and the top, and the water passing body is wrapped in the heating radiator body of the heating radiator body, as shown in fig. 10. Compared with the mode of pulling the core at one end, the mode of pulling the core at the two ends can greatly reduce the length of a single heat dissipation cavity core when the heat dissipation cavities with the same length are produced, and the length of the heat dissipation cavity core can be reduced by half. Because the length of the heat dissipation cavity core is reduced, the core pulling is more convenient, the production difficulty of the heating radiator main body is reduced, and the yield is improved.

Of course, the two ends of the radiator are loose, so that openings are left at the top and the bottom of the radiator main body, and radiator end covers need to be respectively installed at the top and the bottom of the radiator main body in order to improve the aesthetic degree of the radiator, wherein the bottom end cover is shown in fig. 11, and the top end cover is shown in fig. 12. The dashed lines in fig. 11 are schematic views of the cavity in the bottom end cap in perspective.

The foregoing is illustrative of the preferred embodiment of the present invention and is not to be construed as limiting the invention in any way. Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments by the technical entity of the present invention should fall within the protection scope of the technical solution of the present invention.
