[0033] The optimized cooling structure of the rocket engine in the utility model has the advantages that:
[0034] Cooling medium circulation
[0035] Starting water pump: first, the first water pump 30 and the second water pump 40 are started, and they respectively provide flow power for the cooling water in the first conveying pipe 3 and the second conveying pipe 4.
[0036] Cooling water circulation: the cooling water is sucked from a water source (such as a water tank or a cooling system), enters the first conveying pipe 3 through the first water pump 30, flows through the first flow-through area of the arc-shaped hollow plate 1, and then passes through the heat-conducting plate 5 and the heat-conducting pipe 2 around the engine to absorb the heat generated by the engine. Subsequently, the heated cooling water flows back to the cooling system or is cooled again through the second conveying pipe 4 and the second water pump 40, forming a closed circulation.
[0037] Heat conduction and dispersion
[0038] Heat-conducting plate 5 effect: the heat-conducting plate 5 on the inner wall of the arc-shaped hollow plate 1 directly contacts the engine shell, rapidly conducts the high-temperature heat generated during the operation of the engine to the inside of the arc-shaped hollow plate 1.
[0039] Heat-conducting pipe 2 enhancement: the heat-conducting pipe 2 fixed between the two arc-shaped hollow plates 1 further enhances the heat conduction, so that the heat can be more quickly transmitted and dispersed between the two arc-shaped hollow plates 1.
[0040] Air flow and heat dissipation
[0041] Air inlet 10 introduces cold air: the design of the downwardly inclined air inlet 10 enables external cold air to be more effectively introduced into the inside of the arc-shaped hollow plate 1 and exchanged with the cooling water and the heat-conducting plate 5.
[0042] Air outlet 14 discharges hot air: the air outlet 14 opened at the bottom is used to discharge the hot air after heat exchange, forming continuous air flow, which helps to take away the heat during the cooling process.
[0043] Partitioned cooling and efficiency improvement
[0044] First and second flow-through areas: the inside of the arc-shaped hollow plate 1 is divided into a first flow-through area and a second flow-through area by the partition plate 11, and this partitioned design enables the cooling water to more targetedly cool different parts of the engine, improving the efficiency and targeting of the cooling.
[0045] Heat-conducting groove 6 enhances heat dissipation: the vertical heat-conducting groove 6 on the outer wall of the arc-shaped hollow plate 1 increases the area of heat conduction, which helps to transfer more heat to the external environment, further improving the cooling effect.
[0046] Structural stability and durability
[0047] Vertical plate 50 and connecting plate 51: the vertical plate 50 and the connecting plate 51 in the arc-shaped hollow plate 1 provide stable support for the heat-conducting plate 5, ensuring the reliability and durability of the cooling structure during the rocket launch and operation.
[0048] Extension plate 52 optimization layout: the extension plate 52 on the side of the vertical plate 50 away from the heat-conducting plate 5 optimizes the layout of the water pipe 13, prevents damage caused by water flow impact or vibration, and improves the overall stability of the cooling system.
[0049] In summary, the rocket engine optimized cooling structure realizes efficient, uniform and reliable cooling of the rocket engine through the circulation of the cooling medium, heat conduction and dispersion, air circulation and heat dissipation, partition cooling and efficiency improvement, and structural stability and durability design, ensuring the stable operation of the rocket engine in extreme working environment.
