[0028] Example 1: As Figure 1 and Figure 2As shown, a high-efficiency cooling cast aluminum heater includes a heating element 1 and a fixing frame 2. The heating element 1 is divided into two semi-cylinders 3 with a through circular groove 4 in the middle. The cylindrical surface of the semi-cylinder 3 has a storage groove 5 that penetrates the inner and outer walls. The inner wall surface of the semi-cylinder 3 has a vertical groove 6, and the outer wall surface of the semi-cylinder 3 has a horizontal groove 7. The fixing frame 2 is divided into a base plate 11 and a connecting frame 12. The base plate 11 has a square opening 13 in the middle that penetrates the upper and lower surfaces of the base plate 11. A fan 14 is installed on the inner wall of the connecting frame 12. There are two connecting frames 12 and two fans 14, which are installed at both ends of the upper surface of the base plate 11. The heating element 1 is located between the two connecting frames 12 and is coaxial with the fan 14.

[0029] Furthermore, the outer surface of the semi-cylinder 3 has two wiring ports 8, and the connection point of the two semi-cylinders 3 has four threaded holes 9. The two semi-cylinders 3 are connected by bolts 10. The two semi-cylinders 3 are joined together and fastened with bolts 10. The fan 14 is installed on the inner wall of the connecting frame 12. The connecting frame 12 and the base plate 11 are fixed. The element to be heated is placed into the circular groove 4 through the access slot 5. The vertical groove 6 on the inner wall of the heating element 1 and the horizontal groove 7 on the outer wall form an interlaced heat dissipation channel, increasing the heat dissipation surface area.

[0030] Example 2: Figure 3 and Figure 5 As shown, a high-efficiency cooling cast aluminum heater is provided. A heat insulation plate 15 is placed between the two end faces of the heating body 1 and the two connecting frames 12. The two end faces of the semi-cylinder 3 have through holes 17 for fixing and connecting. The bottom plate 11 has eight through fixing holes 16 to fix the two connecting frames 12 at both ends. The heat insulation plate 15 has six through holes 17, four of which fix the heat insulation plate 15 to the connecting frames 12, and two of which connect the connecting frames 12 and the heating body 1.

[0031] Furthermore, the heating element 1 and the connecting frame 12 are isolated from each other by the heat insulation plate 15 to prevent the heating element 1 from losing heat through heat transfer. The heating element 1, the heat insulation plate 15 and the connecting frame 12 are fixed through the through hole 17. The connecting frame 12 is fixed to both ends of the upper surface of the base plate 11 through the fixing hole 16 to ensure that the entire device is firmly connected.

[0032] Example 3: Figure 5 and Figure 7 As shown, a high-efficiency cooling cast aluminum heater is provided. The fan 14 includes fan blades 18, a housing 19, and a power cord 20. The housing 19 has through holes 17 at its four corners. The connecting frame 12 has several through holes 17. The upper left and right corners of the inner wall of the connecting frame 12 have limiting blocks 22. The fan 14 is fixed to the inner wall of the connecting frame 12 through the through holes 17 on the limiting blocks 22. The connecting frame 12 has power slots 21 on both sides for placing the power cord 20.

[0033] Furthermore, align the two upper corners of the fan 14 housing 19 with the limiting block 22, and fix it to the inner wall of the connecting bracket 12 through the through hole 17. Note the rotation direction of the fan 14, so that the two fans 14 are placed face to face to form forced convection and achieve a rapid cooling effect.

[0034] Working Principle: This high-efficiency cooling cast aluminum heater achieves efficient heating and heat dissipation through structural optimization and forced convection. Its core heating element 1 is composed of two semi-cylinders 3 with access slots 5 connected by bolts 10 and threaded holes 9. The circular groove 4 formed after the merger houses the heating element. The wiring port 8 connects to the power supply for rapid heating. The vertical groove 6 on the inner wall and the horizontal groove 7 on the outer wall form staggered heat dissipation channels to increase the heat dissipation area. The two ends of the heating element 1 are isolated from the connecting frame 12 by heat insulation plates 15 with through holes 17, blocking the conduction of heat to the fixed frame 2. At the same time, bolts 10 are used to penetrate the heat. Through hole 17 enables a stable connection of components. Two sets of fans 14 are respectively installed on the inner wall of the connecting frame 12 and mounted on the limiting block 22 through the outer shell 19. The fans 14 are arranged face to face to form forced convection. The power line 20 led out from the power slot 21 drives the fan blades 18 to rotate, accelerating the circulation of air along the heat dissipation channel. The entire device is connected to the through hole 17 through the fixing hole 16 of the base plate 11. The base plate 11 has a square opening 13 in the middle to facilitate heat dissipation. While ensuring structural stability, it significantly improves heat dissipation efficiency and realizes rapid cooling of the heating element 1 and efficient utilization of thermal energy.
