[0023] When the multi-faceted heat sink provided in Embodiment 1 of the present invention is implemented, the first cold channel 21 and the second cold channel

[0024] The first and second cold channels are directly connected to the outside world, and the cold air directly enters the cold channel through the first cold channel air inlet, the second cold channel air inlet and the third cold channel air inlet; the heat medium enters the first core 2 from the first hot channel air inlet, and then enters the second hot channel through the first hot channel air outlet; finally, it enters the third hot channel from the second hot channel air outlet, and is discharged from the third hot channel air outlet to complete the heat exchange. The heat medium flows and exchanges heat with the three-sided cold air along the U-shaped path in the radiator body 1. Compared with the traditional plate-fin radiator, the multi-sided radiator provided by the present invention is integrated into a rectangular structure with a simple and ingenious structure and low cost. It can greatly increase the heat medium flow path in a limited space and prolong the heat exchange time between the heat medium and the refrigerant. The setting of the three-sided refrigerant air inlet surface greatly increases the air flow rate and increases the heat exchange area between the refrigerant and the heat medium. Therefore, the flow heat dissipation capacity of the multi-sided radiator is greatly improved, and the heat exchange efficiency is significantly improved, which can further improve the utilization rate of energy and achieve resource conservation.

[0025] Preferably, the multi-faceted heat sink provided in Embodiment 1 of the present invention is Figure 1 The heat sink body 1 includes a first end cap 5, a second end cap 6, a third end cap 7 and a fourth end cap 8; the first end cap 5 includes a first end cap air inlet (not shown in the drawings) connected to the external heat medium and a first end cap air outlet (not shown in the drawings) connected to the air inlet of the first heat channel; the second end cap 6 includes a second end cap air inlet 61 connected to the air outlet of the first heat channel and a second end cap air outlet 62 connected to the air inlet of the second heat channel; the third end cap 7 includes a third end cap air inlet (not shown in the drawings) connected to the air outlet of the second heat channel and a third end cap air outlet (not shown in the drawings) for connecting the air inlet of the third heat channel; the fourth end cap 8 includes a fourth end cap air inlet (not shown in the drawings) for connecting the air outlet of the third heat channel and a fourth end cap air outlet (not shown in the drawings) for discharging the heat medium.

[0026] When the multi-faceted heat sink provided in Example 1 of the present invention is implemented, the heat medium enters the first end cap 5 from the outside through the first end cap air inlet, and then enters the first hot channel through the first end cap air outlet to exchange heat with the cold air in the first cold channel 21. After the heat exchange in the first core 2 is completed, the heat medium enters the second end cap 6 through the second end cap air inlet 61, and then enters the second hot channel of the second core 3 through the second end cap air outlet 62 to exchange heat with the cold air in the second cold channel. After the heat exchange in the second core 3 is completed, the heat medium enters the third end cap 7 through the third end cap air inlet, and then enters the third hot channel through the third end cap air outlet to exchange heat with the cold air in the third cold channel. After the heat exchange is completed, the heat medium enters the fourth end cap 8 through the fourth end cap air inlet, and finally is discharged from the fourth end cap air outlet. It is simpler to combine the end cap and the core into an L-shaped fluid path than to directly produce a heat sink with an L-shaped fluid path. It only needs to simply assemble the parts, which can save a certain amount of production costs for the enterprise.

[0027] The multi-faceted heat sink provided in Embodiment 1 of the present invention is preferably configured as follows: Figure 1 The first end cap 5 includes a first pin seat 51 and a first tube pin (not shown in the drawings); the first pin seat 51 is welded to the first core body 2; a cavity is arranged inside the first pin seat 51; a first end cap air inlet is provided on the top surface of the first pin seat 51; the first tube pin can be engaged into the internal cavity of the first pin seat 51 through the first end cap air inlet; a first end cap air outlet is provided on one side of the first pin seat 51; a cavity is arranged inside the first tube pin, and a hole for connecting the internal cavity of the first tube pin with the outside is provided on the top surface of the first tube pin; a hole for connecting the internal cavity of the first tube pin and the first end cap air outlet is provided on the side surface of the first tube pin.

[0028] When the multi-faceted heat sink provided in Embodiment 1 of the present invention is implemented, the first pipe pin is screwed into the first pin seat 51 through a thread. Since the first pipe pin has a cavity inside and a hole is formed on the top surface of the first pipe pin, the heat medium enters the first pipe pin's internal cavity through the hole on the top surface of the first pipe pin, and then enters the first heat channel through the hole formed on the side of the pipe pin that connects the first pipe pin's internal cavity and the first head outlet. The first pin seat 51 is connected to the first core 2 by welding, and then the first pipe pin is screwed into the first pin seat 51 through a thread, which greatly reduces the number of assembly parts, reduces the difficulty of assembly, and also increases the structural reliability of the multi-faceted heat sink.

[0029] Preferably, refer to Figure 1, the multi-faceted heat sink provided by Example 1 of the present invention, the second head 6 includes a second pin seat 63 and a second pipe pin 64; the second pin seat 63 is welded to the first core 2; the second pin seat 63 is welded to the second core 3; a cavity is arranged inside the second pin seat 63; the second pipe pin 64 can be snapped into the cavity of the second pin seat 63; the top surface of the second pin seat 63 is provided with a hole for snapping the second pipe pin 64 into the internal cavity of the second pin seat 63; a second head air outlet 62 is arranged on one side of the second pin seat 63; a second head air inlet 61 is arranged on the other side of the second pin seat 63; a cavity is arranged inside the second pipe pin 64; a hole for connecting the internal cavity of the second pipe pin 64 and the second head air inlet 61 is arranged on the side of the second pipe pin 64; a hole for connecting the internal cavity of the second pipe pin 64 and the second head air outlet 62 is also arranged on the side of the second pipe pin 64;

[0030] After the heat medium comes out from the air outlet of the first heat channel, it flows into the inner cavity of the second pipe pin 64 through the hole opened on the side of the second pipe pin 64 that connects the inner cavity of the second pipe pin 64 and the air inlet 61 of the second head, and then enters the second heat channel of the second core 3 through the hole opened on the side of the second pipe pin 64 that connects the inner cavity of the second pipe pin 64 and the air outlet 62 of the second head. The top surface of the second pipe pin 64 does not have a hole connected to the inner cavity of the second pipe pin 64, so the heat medium can only enter the second core 3 through the second head 6. The second pipe pin 64 and the second pin seat 63 are tightened by threads, the second pin seat 63 is welded to the first core 2, and the second pin seat 63 is welded to the second core 3. Compared with fixing the head by a large number of assembly parts, the head structure of the multi-faceted radiator provided by the present invention is simple, and the difficulty of equipment is greatly reduced. The second pipe pin 64 is detachably connected to the second pin seat 63, so different types of pipe pins can be replaced to meet different actual use requirements; for example, if the top of the second pipe pin is also provided with a hole connecting the outside world and the inside of the pipe pin, and the side is provided with a hole connecting the second head air inlet 61, then the independent heat exchange of the first core 2 can be achieved. Therefore, the multi-faceted radiator provided in Example 1 of the present invention also has the advantages of flexibility and versatility, and can meet a variety of heat exchange requirements. When the pipe pin is damaged, it can also be replaced separately without replacing the entire head, which can save maintenance costs for the enterprise.

[0031] Further, the multi-faceted heat sink provided in Example 1 of the present invention, referring to Figure 1The third end cap 7 includes a third pin seat 71 and a third pipe pin (not shown in the drawings); the third pin seat 71 is welded to the second core body 3; the third pin seat 71 is welded to the third core body 4; a cavity is arranged inside the third pin seat 71; the third pipe pin can be engaged in the cavity of the third pin seat 71; a hole is provided on the top surface of the third pin seat 71 for engaging the third pipe pin into the inner cavity of the third pin seat 71; a third end cap air outlet is arranged on one side of the third pin seat 71; a third end cap air inlet is arranged on the other side of the third pin seat 71; a cavity is arranged inside the third pipe pin; a hole is provided on the side of the third pipe pin for connecting the inner cavity of the third pipe pin and the air inlet of the third end cap; a hole is also provided on the side of the third pipe pin for connecting the inner cavity of the third pipe pin and the air outlet of the third end cap;

[0032] After the heat medium comes out from the air outlet of the second heat channel, it flows into the inner cavity of the third pipe pin through the hole opened on the side of the third pipe pin that connects the inner cavity of the third pipe pin and the air inlet of the third head, and then enters the third heat channel of the third core 4 through the hole opened on the side of the third pipe pin that connects the inner cavity of the third pipe pin and the air outlet of the third head. The top surface of the third pipe pin does not have a hole connected to the inner cavity of the third pipe pin, so the heat medium can only enter the third core 4 through the second head 6. Like the second pipe pin, since the third pin seat 71 is welded to the second core 3, the third pin 71 seat is welded to the third core 4, and the third pipe pin and the third pin seat 71 are detachably connected, different types of pipe pins can be replaced when facing different actual use requirements, meeting different requirements, flexible and multi-purpose, and meeting a variety of heat exchange requirements.

[0033] Further, the multi-faceted heat sink provided in Example 1 of the present invention, referring to Figure 1 The fourth end cap 8 includes a fourth pin seat 81 and a fourth tube pin (not shown in the drawings); the fourth pin seat 81 is welded to the third core body 4; a cavity is arranged inside the fourth pin seat 81; a fourth end cap air outlet is provided on the top surface of the fourth pin seat 81; the fourth tube pin can be engaged into the internal cavity of the fourth pin seat 81 through the fourth end cap air outlet; a fourth end cap air inlet is provided on one side surface of the fourth pin seat 81; a cavity is arranged inside the fourth tube pin, and a hole for connecting the internal cavity of the fourth tube pin with the outside is provided on the top surface of the fourth tube pin; a hole for connecting the internal cavity of the fourth tube pin and the air inlet of the fourth end cap is provided on the side surface of the fourth tube pin.

[0034] After completing the heat exchange in the third core 4, the heat medium enters the cavity of the fourth pipe pin through the hole opened on the side of the fourth pipe pin, and is finally discharged through the fourth head outlet on the top surface of the fourth pipe pin. The fourth pipe pin and the fourth pin seat 81 are tightened by threads, and the fourth pin seat 81 is welded to the third core 4. Compared with fixing the head by a large number of assembly parts, the head of the multi-faceted radiator provided by the present invention is simple to assemble, and the fourth pipe pin and the fourth pin seat 81 are detachably connected. Therefore, different types of pipe pins can be replaced when facing different actual use requirements, meeting different requirements, flexible and multi-purpose, and meeting a variety of heat exchange requirements. When the pipe pin is damaged, it can also be replaced separately without replacing the entire head, which can save maintenance costs for the enterprise.

[0035] Preferably, refer to Figure 1 A fan 9 is also provided inside the radiator body 1; the air inlet of the fan 9 is connected to the first cold channel air outlet, the second cold channel air outlet, and the third cold channel air outlet respectively; the air outlet of the fan 9 is connected to the side of the radiator body 1 where the heat exchange core is not provided.

[0036] After the cold air enters the first core 2, the second core 3, and the third core 4 and completes the heat exchange, the cold air can be drawn out from the radiator body 1 through the fan 9 to prevent the cold air after the heat exchange from being trapped in the radiator body 1 and being difficult to be discharged, thereby affecting the normal operation of the radiator.
