[0004] With respect to the above-mentioned related technologies, the inventors found that each heat sink fin needs to be installed one by one on the base by the installer, which requires accurate adjustment of the assembly of each heat sink fin, otherwise leakage is likely to occur, thus resulting in labor-intensive assembly of the entire radiator. Summary of the invention

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-7 This application is described in further detail.

[0043] Example 1

[0044] The present application embodiment discloses a high-sealing plate-tooth radiator. Figure 1 A high-sealing plate-tooth radiator includes a base 1 and a heat sink 2.

[0045] A main channel for liquid circulation is arranged in the base 1, and the main channel includes two independent fluid channels 11. Two wiring tubes 12 are arranged on the base 1, and the two wiring tubes 12 are connected to the fluid channels 11 one by one. A plurality of liquid outlets 13 connected to the heat sink 2 are arranged on the base 1 corresponding to each fluid channel 11, so that the liquid to be cooled enters the fluid channel 11 through the wiring tube 12, and then the liquid in the fluid channel 11 enters the heat sink 2 through the liquid outlet holes 13, and then flows through the heat sink 2, enters another fluid channel 11 from the liquid outlet holes 13 on another fluid channel 11, and is discharged by the corresponding wiring tube 12, so that the liquid to be cooled flows through the heat sink 2 to reduce the temperature and then is discharged, thereby achieving the heat dissipation effect.

[0046] The heat sink 2 includes a base plate 21, on which a plurality of heat dissipation tooth plates 22 are arranged, and on which a secondary flow channel connected to the main flow channel is arranged; that is, the liquid to be cooled in the main flow channel enters the secondary flow channel of the heat dissipation tooth plate 22, and because the heat dissipation area of ​​the heat dissipation tooth plate 22 itself is increased, the heat exchange rate of the remaining external air is accelerated, and the heat of the liquid can be quickly taken away, thereby facilitating the improvement of the heat dissipation effect. The base plate 21 is provided with positioning grooves 24 for the heat dissipation tooth plates 22 to pass through one by one, and the heat dissipation tooth plates 22 are welded and fixed on the base plate 21. That is, after the heat dissipation tooth plates 22 are inserted into the positioning grooves 24, only the connection needs to be welded, so as to ensure the sealing of the connection between the heat dissipation tooth plates 22 and the base plate 21.

[0047] In order to ensure the sealing effect of welding, the end of the heat dissipation tooth plate 22 close to the base 1 protrudes from the substrate 21, that is, because the heat dissipation tooth plate 22 protrudes from the substrate 21, a step is formed between the substrate 21 and the heat dissipation tooth plate 22, and then welding can be completed by welding around the step, so as to facilitate welding and ensure the sealing after welding. In order to ensure that the heat dissipation tooth plate 22 can protrude from the substrate 21, and the protruding height is controllable, the end of the positioning groove 24 away from the base 1 is provided with abutting ring 25, and the heat dissipation tooth plate 22 is provided with a boss 26 abutting against the abutting ring 25, and the distance h from the end face of the positioning groove 24 to the top face of the abutting ring 25 is less than the distance H between the bottom face of the boss 26 and the end face of the heat dissipation tooth plate 22, so that after the heat dissipation tooth plate 22 passes through the positioning groove 24, when the boss 26 abuts against the abutting ring 25, its end must protrude from the end face of the substrate 21, and the protruding height (Hh) is controllable, so as to ensure the subsequent welding effect.

[0048] The secondary flow channel includes a plurality of branch channels 23 arranged in the heat dissipation tooth plate 22. Both ends of the branch channels 23 are connected to the liquid outlet holes 13 on the two fluid channels 11 one by one, so that the liquid can pass through the heat dissipation tooth plate 22 evenly from the branch channels 23, thereby ensuring the heat dissipation effect.

[0049] The substrate 21 is detachably arranged on the base 1, and a seal is arranged between the base 1 and the substrate 21. That is, the entire radiator can be assembled by simply installing the substrate 21 on the base 1, which is convenient for personnel to assemble and improves assembly convenience.

[0050] The seal includes a sealing ring groove arranged outside each fluid channel 11, and a sealing ring 14 is arranged in the sealing ring groove, that is, after the substrate 21 is pressed on the base 1, the outflow holes corresponding to the two fluid channels 11 are isolated from each other, thereby ensuring that the liquid can all flow through the secondary flow channel in the heat dissipation tooth plate 22, thereby ensuring the heat dissipation effect. A positioning groove 24 is arranged between the two fluid channels 11, that is, the positioning groove 24 is arranged on the base 1 between the two sealing ring grooves. The substrate 21 is provided with a plurality of locking screws 3 screwed on the base 1, that is, the substrate 21 is gradually pressed and locked on the base 1 by the locking screws 3, so that the sealing ring 14 is pressed and fitted to complete the assembly sealing effect.

[0051] The implementation principle of a high-sealing plate-tooth radiator in an embodiment of the present application is as follows: the liquid to be cooled enters the fluid channel 11 therein through the wiring tube 12, and then the liquid in the fluid channel 11 enters the heat sink 2 through the liquid outlet hole 13, and then flows through the heat sink 2, enters another fluid channel 11 from the liquid outlet hole 13 on another fluid channel 11, and is discharged by the corresponding wiring tube 12, so that the liquid to be cooled flows through the heat sink 2 to reduce the temperature and then is discharged, thereby achieving the heat dissipation effect.

[0052] Example 2

[0053] The difference between this embodiment and embodiment 1 is that:

[0054] The secondary flow channel includes a plurality of branch flow channels 23 arranged in the heat dissipation tooth plate 22. The plurality of branch flow channels 23 are divided into two groups. The two groups of branch flow channels 23 are respectively connected to the liquid outlet holes 13 on the two fluid channels 11 one by one. A connecting groove 27 is arranged on the heat dissipation tooth plate at one end of the plurality of branch flow channels 23 away from the base 1. The top ends of the plurality of branch flow channels are connected to the connecting groove. A sealing cover 28 is arranged on the connecting groove to block the top end of the connecting groove to prevent leakage.

[0055] Thus, the liquid can evenly pass through the heat dissipation tooth plate 22 from one group of branch channels 23 and then be collected in the connecting groove, and then enter another group of branch channels from the connecting groove and flow into another fluid channel, thereby achieving the effect of circulating heat dissipation, thereby ensuring the heat dissipation effect. At the same time, the setting of the connecting groove is simpler than the bending branch channel in Example 1, and the production cost is low and economical and efficient.

[0056] Example 3

[0057] The difference between this embodiment and embodiment 2 is that:

[0058] The base 1 corresponding to each fluid channel 11 is provided with a countersunk slot 15 connected to a plurality of heat sinks 2, so that the smoothness of the fluid channel can be ensured without considering the accuracy problem during processing, thereby reducing the processing cost and facilitating installation by personnel.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
