Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile water pump especially relates to a heat dissipation structure for automobile water pump. BACKGROUND

[0002] The automobile water pump is the key component of the engine cooling system, and through driving the cooling liquid circulation to heat dissipation for the engine, its own under high load operation due to mechanical friction and high temperature cooling liquid conduction generates a large amount of heat, if not promptly dissipate, will lead to bearing wear and tear, aging of sealing element, cooling liquid cavitation and other problems, and further cause engine overheating, emission overproof even security risk, therefore, the heat dissipation structure for automobile water pump is very necessary, it passes through the optimization flow passage, fin and other mechanical structure, upgrade high thermal conductivity material and use intelligent temperature control technology, effectively control the water pump key component temperature, maintain the cooling system efficiency, guarantee the engine stable operation under various working conditions, prolong the service life of the whole vehicle.

[0003] The existing automobile water pump heat dissipation structure comprehensively uses multiple principles to realize high-efficiency heat dissipation, uses high-thermal-conductivity materials and optimizes the flow passage design to strengthen heat conduction and convection, enhances heat radiation through heat dissipation fins and radiation coating, adopts phase change heat dissipation and active cooling technologies such as heat pipes and independent water cooling circuits for extreme working conditions, suppresses cooling liquid cavitation through inducer and pressure balance cavity to ensure heat dissipation stability, and simultaneously, realizes intelligent temperature control and coordination with the engine thermal management system by means of temperature sensor and ECU linkage to meet the heat dissipation requirements of compact and high-power engines.

[0004] In the actual application of the heat dissipation structure for automobile water pump, although the existing design improves the heat dissipation efficiency through material upgrading and flow passage optimization, there are still significant limitations. When the automobile water pump is in a long-time high-load working condition, the mechanical friction heat of the impeller and bearing and the cooling liquid conduction heat will quickly accumulate, causing the local temperature to break through the material tolerance threshold. At this time, even if the heat dissipation structure operates at full capacity, it is difficult to effectively export the heat in a short time, and eventually triggers the overheating protection mechanism, forcing the water pump to stop and cool down. Frequent shutdown and maintenance not only interrupts the continuous operation of the vehicle power system, reduces transportation efficiency, but also aggravates component wear due to thermal expansion and contraction effect, shortens the service life of the water pump. In addition, the flowability of the cooling liquid drops sharply after shutdown, which may cause hot spots in the local area of the engine, further causing cooling system failure. This cycle of high-load operation overheating shutdown-maintenance restart exposes the passivity and hysteresis of the existing heat dissipation structure under extreme working conditions, and fails to fundamentally realize dynamic balance and real-time regulation of heat, becoming a key bottleneck restricting the efficient and stable operation of the automobile water pump.

[0034] The heat dissipation assembly comprises a circulating water pump 10, a conveying pipe 11, a heat dissipation pipe 12 and a return pipe 13. The circulating water pump 10 is fixedly connected to one side of the protection shell 4 to provide power for the movement of cooling water. The input end of the circulating water pump 10 is connected to one end of the outlet pipe 9. One end of the conveying pipe 11 is fixedly connected to the output end of the circulating water pump 10, and is used for conveying cooling water into the heat dissipation pipe 12. One end of the heat dissipation pipe 12 is fixedly connected to one end of the conveying pipe 11, and is used for absorbing heat generated by the automobile water pump 1. One end of the return pipe 13 is fixedly connected to one end of the heat dissipation pipe 12, and is used for guiding the cooling water after absorbing heat into the inside of the water storage tank 7. The other end of the return pipe 13 is fixedly connected to the top of the water storage tank 7. The water inlet and outlet assembly comprises a water inlet pipe 2 and a water outlet pipe 3.

[0035] Specifically, when the automobile water pump 1 is running at high speed, the impeller and the bearing rub fiercely, and the cooling liquid continuously conducts. A large amount of heat energy is accumulated on the surface of the pump body. The heat dissipation fins 6 embedded on the outside of the pump body rapidly absorb and diffuse these hot energy by virtue of the wave-shaped biomimetic structure and the high-efficiency heat-conducting aluminum alloy material. As the heat spreads along the surface of the fins, the heat dissipation pipe 12 hidden in the deep part of the fin array accurately guides the heat energy into the pipe. At this time, the intelligent temperature control system monitors the temperature threshold trigger, and the circulating water pump 10 starts suddenly. The strong power drives the cooling water to flow into the heat dissipation pipe 12 at a stable flow rate. The clear cooling liquid shuttles in the pipeline and fully contacts the high temperature on the pipe wall, and finally is transported to a remote place through the circulating system, so as to ensure that the automobile water pump 1 is always in a safe operating temperature range.

The butt joint grooves 16 are symmetrically arranged on one side of the protection shell one 4 and the protection shell two 5. A plurality of butt joint blocks 17 are fixedly connected to one side of the protection shell one 4 and the protection shell two 5, and are used for connecting the protection shell one 4 and the protection shell two 5.

The outer wall of each fixing pin 18 is fixedly connected with the limiting plate 19. The limiting plate 19 limits the movement range of the fixing pin 18. The outer wall of each limiting plate 19 is slidably connected in the butt joint block 17. A plurality of springs 20 are arranged in each butt joint block 17, and provide elastic force for the fixing pin 18. One end of each spring 20 is fixedly connected in the butt joint block 17. The other end of each spring 20 is fixedly connected to one side of the fixing pin 18.

[0037] Specifically, when the automobile water pump 1 is protected and assembled, first, hold the protection shell one 4 with both hands, carefully align the positioning pins 15 and the butt joint blocks 17 on the side of the protection shell one 4 with the positioning holes 14 and the butt joint grooves 16 on one side of the protection shell two 5, and then slowly force the protection shell one 4 and the protection shell two 5 to be mutually buckled, so that the two protection shells are tightly engaged.
