[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention divides the interior of the engine radiator body into an inner water cavity and an outer water cavity. Hot water enters the inner copper tube from the water inlet. Since one side of the inner copper tube is close to the engine, the temperature of the inner water cavity rises due to the temperature of the engine. The outer water cavity is closer to the outside, so that the temperature in the outer water cavity is significantly lower than that in the inner water cavity, so that the inner and outer cavities form a hot surface and a cold surface. The establishment of the cold surface increases the temperature difference between the medium water that needs to be cooled and the temperature in the cold water cavity, and the heat transfer is intense, which accelerates the internal heat exchange efficiency. The outer water cavity and the inner water cavity are separated by a partition copper plate. The copper plate is made of copper and has good heat transfer performance. It is equipped with a number of internal heat dissipation fins to transfer the heat of the water in the inner water cavity to the water in the outer water cavity. The inner water cavity is composed of a plurality of outer heat dissipating fins, and the outer water cavity can transfer the temperature outwards through a plurality of outer heat dissipating fins, and the outer heat dissipating fan can dissipate the heat by wind, so that the heat dissipation effect of the whole radiator is improved; in addition, the water body is transported through the copper tube, and the copper tube has good thermal conductivity and can transfer the temperature of the water body to the water. The water body first transfers heat to the inner water cavity through the inner cavity copper tube and the copper tube fins, and then the water body flows to the outer cavity copper tube at the outer water cavity for cold surface heat exchange. Finally, the internal heat exchange water medium is dissipated outwards step by step under the action of the inner heat dissipating fins, the outer heat dissipating fins and the heat dissipating fan, so as to ensure that there is a low-temperature water cavity with a relatively large temperature difference in the radiator, so that the internal heat dissipation process can be cyclically carried out.

[0020] 2. Use a combined mounting plate to fix the fan mounting plate on the front end of the external cooling fins, so that the first cooling fan can dissipate heat and cool the external cooling fins, thereby improving the cooling effect of the radiator. The bottom cooling layer uses multiple second cooling fans to dissipate heat and cool the bottom pipe layer; the water temperature in the external water cavity close to the cooling fan surface is rapidly reduced.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figure 1-5 The present invention provides an embodiment: an engine copper core structure radiator, comprising an engine radiator body 1, an upper pipe installation layer 3 is threadedly installed on the upper part of the engine radiator body 1, a bottom pipe layer 2 is threadedly installed on the lower part of the engine radiator body 1, and a plurality of external heat dissipation fins 4 are arranged on the outer wall of the bottom pipe layer 2 and the engine radiator body 1;

[0029] Also includes:

[0030] The inner water chamber 12 is arranged inside the engine radiator body 1 on one side close to the engine;

[0031] The outer water cavity 13 is arranged inside the engine radiator body 1 on a side away from the engine. A partition copper plate 14 is integrally arranged between the inner water cavity 12 and the outer water cavity 13 . A plurality of inner cooling fins 15 are arranged on the outer wall of the partition copper plate 14 close to the outer water cavity 13 .

The copper tube material has good thermal conductivity, and can exchange heat between the water in the tube and the water outside the tube to achieve the effect of cooling the water in the tube. The connecting elbow 21 plays the effect of combined connection, so that the water in the tube can flow downstream to the outer copper tube 22 for heat dissipation. At the same time, when the water in the tube flows at the connecting elbow 21, it also exchanges heat with the water in the bottom pipe layer 2, thereby improving the heat exchange efficiency of the water.

[0033] See also Figure 3 , Figure 4 A plurality of copper tube fins 18 are welded on the outer walls of the inner copper tube 17 and the outer copper tube 22. The inner copper tube 17 and the outer copper tube 22 are welded by a plurality of U-shaped tubes 24 and straight tubes. The copper tube fins 18 can improve the thermal conductivity of the copper tube and make the water in the tube cool down faster. The combination of the U-shaped tube 24 and the straight tube can increase the flow time of the water in the radiator, and the U-shaped tubes 24 are separated by water to ensure sufficient heat exchange of the water in the tube.

The fan mounting plate 8 is fixed to the front end of the external heat dissipation fin 4 by using the combined mounting plate 6, so that the first heat dissipation fan 9 can dissipate heat and cool the external heat dissipation fin 4, thereby improving the heat dissipation effect of the radiator.

[0035] See also Figure 1 , Figure 2 A bottom heat dissipation layer 10 is threadedly installed below the fan mounting plate 8, and the bottom heat dissipation layer 10 is threadedly connected to the bottom pipe layer 2 through fixing bolts 7. A plurality of second heat dissipation fans 11 are threadedly installed on the outer wall of the bottom heat dissipation layer 10. The bottom heat dissipation layer 10 uses the plurality of second heat dissipation fans 11 to dissipate heat and cool the bottom pipe layer 2, so that the water temperature in the outer water cavity 13 close to the heat dissipation fan surface is rapidly reduced.

[0036] See also Figure 2 , Figure 5 The front and rear ends of the outer walls of the first cooling fan 9 and the second cooling fan 11 are both threadedly mounted with protective mesh covers 30, which protect the cooling fans and prevent debris from entering the interior and affecting the normal operation of the fans.

[0037] See also Figure 2 , Figure 5 The outer walls of the fan mounting plate 8 and the front end surface of the bottom heat dissipation layer 10 are both threadedly installed with a disassembly and maintenance plate 28, and the four corners of the outer wall of the disassembly and maintenance plate 28 are threadedly installed with maintenance plate bolts 29. The disassembly and maintenance plate 28 and the maintenance plate bolts 29 facilitate the user to disassemble, clean and replace the heat dissipation fan.

[0038] See also Figure 3 , Figure 4A control mechanism 25 is installed on the internal thread of the upper pipe installation layer 3, and two temperature sensors 26 are installed on the lower end thread of the control mechanism 25. The output end of the temperature sensor 26 is electrically connected to the input end of the control mechanism 25, and the two temperature sensors 26 extend to the inside of the inner water cavity 12 and the outer water cavity 13 respectively. A display screen 27 is installed on the outer wall thread of the front end surface of the upper pipe installation layer 3, and the input end of the display screen 27 is electrically connected to the output end of the control mechanism 25. The temperature sensor 26 is used to detect the water temperature changes in the inner water cavity 12 and the outer water cavity 13, and feed it back to the control mechanism 25, and the control mechanism 25 feeds back to the display screen 27, so that the user can know the temperature change data when checking the engine radiator.

[0039] See also Figure 3 , Figure 4 One end of the inner copper tube 17 is provided with a water inlet 16, and one end of the outer copper tube 22 is provided with a water outlet 23. The water inlet 16 is used for hot water entering the engine. The hot water becomes cold water after internal heat exchange and is sent to the engine again from the water outlet 23 for circulation and heat dissipation.

[0040] See also Figure 3 A first flange 19 is threadedly installed between the engine radiator body 1 and the upper pipe installation layer 3, and a second flange 20 is threadedly installed between the engine radiator body 1 and the bottom pipe layer 2. The first flange 19 and the second flange 20 are both used to fix the copper pipe to improve the stability and firmness of the internal copper pipe.

[0041] Working principle: When in use, the engine radiator body 1 is divided into an inner water chamber 12 and an outer water chamber 13. Hot water enters the inner copper tube 17 from the water inlet 16. Since one side of the inner copper tube 17 is close to the engine, the temperature of the inner water chamber 12 rises due to the temperature of the engine. The outer water chamber 13 is closer to the outside, so that the temperature of the outer water chamber 13 is significantly lower than that of the inner water chamber 12, so that the inner and outer chambers form a hot surface and a cold surface. The establishment of the cold surface increases the temperature difference between the medium water that needs to be cooled and the temperature in the outer water chamber 13, and the heat transfer is intense, which accelerates the internal heat exchange efficiency. The outer water chamber 13 and the inner water chamber 12 are separated by a partition copper plate 14. The copper plate is made of copper material, which has good heat transfer performance. It is equipped with a number of inner heat dissipation fins 15, which can transfer the heat of the water in the inner water cavity 12 to the water in the outer water cavity 13, and the outer water cavity 13 can transfer the temperature outward through a number of outer heat dissipation fins 4, and the external heat dissipation fan can perform wind heat dissipation on it, so that the heat dissipation effect of the entire radiator is improved; in addition, the water is transported through the copper tube, which has good thermal conductivity and can transfer the water temperature to the water. The water first transfers heat to the inner water cavity 12 through the inner cavity copper tube 17 and the copper tube fins 18, and then the water flows to the outer cavity copper tube 22 at the outer water cavity 13 to perform cold surface heat exchange. Finally, the internal heat exchange water medium is gradually dissipated outwards through the inner heat dissipation fins 15, the outer heat dissipation fins 4 and the heat dissipation fan, ensuring that there is a low-temperature water cavity with a relatively large temperature difference in the radiator, so that the internal heat dissipation process can be circulated, and the fan mounting plate 8 is fixed to the front end of the outer heat dissipation fins 4 by using the combined mounting plate 6, so that the first heat dissipation fan 9 can dissipate heat and cool the outer heat dissipation fins 4, thereby improving the heat dissipation effect of the radiator. The bottom heat dissipation layer 10 uses multiple second heat dissipation fans 11 to dissipate heat and cool the bottom pipeline layer 2; the water temperature in the outer water cavity 13 close to the heat dissipation fan surface is rapidly reduced, The copper tube material has good thermal conductivity, and can exchange heat between the water in the tube and the water outside the tube, thereby achieving the effect of cooling the water in the tube. The connecting elbow 21 plays the effect of combined connection, so that the water in the tube can flow downstream to the outer cavity copper tube 22 for heat dissipation. At the same time, when the water in the tube flows at the connecting elbow 21, it also exchanges heat with the water in the bottom pipe layer 2, thereby improving the heat exchange efficiency of the water. The copper tube fins 18 can improve the thermal conductivity of the copper tube, thereby cooling the water in the tube faster. The combination of the U-tube 24 and the straight tube can increase the flow time of the water in the radiator, and the U-tubes 24 are separated by water to ensure sufficient heat exchange of the water in the tube.
