[0021] The following further describes the present utility model in detail with reference to the drawings and specific embodiments. The embodiments of the present utility model are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0022] Embodiment

[0023] Please refer to Figures 1 to 5, in this embodiment, a super silent electronic water pump and a heat pump kettle with a high-strength heat kettle body are provided, including a cooling kettle body 1. The cooling kettle body 1 is made of modified high-strength PP engineering plastic material, which can increase its toughness and strength. At the same time, a flash groove and a flash stop boss are provided at its welding edge, which can improve the welding strength and appearance quality of the product;

[0024] A coolant inlet is provided at the bottom of the front side of the cooling kettle body 1. A kettle lid 2 is installed on the coolant inlet. The kettle lid 2 can be detached from the cooling kettle body 1. After being detached, coolant can be added through the coolant inlet;

[0025] An electronic auxiliary water pump 3 is provided at the upper end of the cooling kettle body 1. The electronic auxiliary water pump 3 is connected to the cooling kettle body 1. It can accelerate the delivery of the coolant in the cooling kettle body 1 to other positions that need to be cooled, accelerate the flow of the coolant, and improve the cooling efficiency. The main shaft material inside the electronic auxiliary water pump 3 is made of SUS303 material, and it has been heat-treated and external cylindrical grinding treatment. The bearing adapted to it uses a graphite self-lubricating bearing, which can reduce the working noise of the water pump and improve the service life of the product;

[0026] At the same time, a plurality of outlets 9 with different directions are provided on the electronic auxiliary water pump 3. After being accelerated by the electronic auxiliary water pump 3, the coolant is discharged from each outlet 9. The outlet 9 is connected to other structures, so that the coolant is delivered everywhere to achieve cooling. At the same time, water pump plugs 7 are also provided on the left and right sides of the electronic auxiliary water pump 3;

[0027] An actuator 4 is provided at the upper end of the electronic auxiliary water pump 3. An actuator plug 8 is provided on the actuator 4. The actuator 4 controls each outlet 9, and a rotary valve is provided at the outlet 9;

[0028] A cooler 5 connected to it is provided on the right side of the cooling kettle body 1. A circulation port 6 is provided on one side of the cooler 5. After the coolant is cooled by other structures, the used coolant will re-enter the cooler 5 from the circulation port 6, be cooled again, and then be injected into the cooling kettle body 1 again for recycling;

[0029] And an electronic expansion valve 12 is provided on the other side of the cooler 5. A refrigerant inlet 10 and a refrigerant outlet 11 are provided on the electronic expansion valve 12. After the coolant re-enters the cooler 5, the electronic expansion valve 12 is opened to allow the refrigerant to enter, so as to realize the re-cooling of the coolant with heat for subsequent continued use.

[0030] During use, the vehicle's antifreeze enters the interior of the assembly of the coolant kettle body 1 through the coolant inlet at the kettle lid 2, and then the rotary valve is controlled by the actuator 4, and flows through multiple different outlets 9 to different functional channels for cooling. The electronic auxiliary water pump 3 can increase the flow rate of the antifreeze and accelerate cooling. Then, the antifreeze brought back by the vehicle's heat enters the cooler 5 through the circulation port 6. After the electronic expansion valve 12 is opened, the refrigerant takes away the heat of the antifreeze for cooling and returns to the interior of the coolant kettle body 1, forming a reciprocating cooling cycle.

[0031] In the present utility model, the main shaft material inside the electronic auxiliary water pump 3 is SUS303 material, and it has been heat-treated and external circle grinding-treated. The bearing uses a graphite self-lubricating bearing, which reduces the working noise of the water pump and improves the service life of the product.

[0032] The material of the coolant kettle body 1 uses high-strength engineering plastics, which increases toughness and strength. The welding edge is increased with a flash groove and a baffle boss to improve the welding strength and appearance quality of the product.
