Description

Technical Field

[0001] The invention relates to the technical field of water pumps, in particular to a water pump body with efficient heat dissipation effect and a heat dissipation method. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. In the actual use of the water pump, the circuit design and performance requirements of the water pump depend to a large extent on the heat dissipation of the water pump controller.

[0003] A waterproof pump with heat dissipation effect recorded in the patent document with patent announcement number CN118008831B includes a waterproof pump body and a deflector, etc.; the deflector is installed on the lower side of the waterproof pump body, which realizes that when the pump is tilted, the counterweight part drives the entire guide ring to slide inside the cylinder body, so that the drainage port is located at the highest point of the guide ring in the tilted state, thereby ensuring that when the liquid level in the water storage chamber reaches the drainage port, the water in the water storage chamber has completely submerged the waterproof pump body, ensuring the heat dissipation effect of the water in the water storage chamber on the waterproof pump body in the tilted state, and enhancing the adaptability of the pump machine. However, in order to make the water pump dissipate heat efficiently, the water pump needs to completely penetrate into the water body and dissipate heat through the flow of internal water body, which has great limitations, and the operator needs to hold the cover body at the upper end of the water pump and put it into the water to adjust the position, which is less convenient. During long-term use of the water pump, the water body contacts the surface of the water pump, which is easy to generate high-temperature water vapor, and the internal temperature of the cylinder is continuously high, affecting the service life.

[0004] Based on this, a water pump body and a heat dissipation method with efficient heat dissipation effect are now provided, which can eliminate the disadvantages of the existing devices. Summary of the invention
