Description

Technical Field

[0001] This utility model relates to the technical field of aluminum cover structures for heat dissipation, and in particular to an aluminum cover structure that enhances heat dissipation. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids; it transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] For example, the aluminum cover structure for heat dissipation disclosed in the utility model patent application number CN201621232789.4 represents a type of prior art. Its main structure consists of a cover body, a circuit board mounting boss, an O-ring seal, and heat dissipation fins. The aluminum cover structure for heat dissipation is achieved through the cooperation of the cover body, the circuit board mounting boss, the O-ring seal, and the heat dissipation fins.

[0004] The transition of the straight ribs inside the traditional aluminum cap is unnatural, which hinders the expansion and contraction of the casting. Stress concentration during the pouring, heat treatment and correction processes can easily lead to cracks. In addition, the contact area between the straight ribs inside the traditional aluminum cap and the coolant is small, resulting in poor heat dissipation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an aluminum cover structure that enhances heat dissipation by allowing direct contact between the heat dissipation bottom cover and the coolant inside the housing assembly. The corrugated ribs and inner corrugated grooves in the heat dissipation bottom cover increase the contact area between the aluminum cover and the coolant. The back of components such as MOSFETs and MCUs that require heat dissipation in the PCBA are in contact with the aluminum cover through thermal grease. The heat dissipation bottom cover is in direct contact with the coolant inside the water pump, thereby dissipating heat from the PCBA and improving the practicality of the equipment.

[0006] This utility model discloses an aluminum cover structure for enhanced heat dissipation, comprising a housing assembly; it also includes a water-isolating sleeve, a heat dissipation bottom cover, a PCBA, and a rear cover. The water-isolating sleeve, heat dissipation bottom cover, and PCBA are all installed inside the housing assembly. The heat dissipation bottom cover is located below the water-isolating sleeve, the PCBA is located below the heat dissipation bottom cover, and the rear cover is installed at the bottom of the housing assembly. The housing assembly supports the water-isolating sleeve, the heat dissipation bottom cover, the PCBA, and the rear cover. The equipment is started by activating the housing assembly. During operation, the water-isolating sleeve isolates the coolant from the key components in the housing assembly. The heat dissipation bottom cover directly contacts the coolant inside the housing assembly. The corrugated ribs and inner corrugated grooves in the heat dissipation bottom cover increase the contact area between the aluminum cover and the coolant. The back of the MOSFETs and MCUs in the PCBA that require heat dissipation contact the aluminum cover with thermal grease. The heat dissipation bottom cover directly contacts the coolant inside the water pump. The heat dissipation bottom cover dissipates heat from the PCBA, and the rear cover protects the PCBA, improving the practicality of the equipment.

[0007] Preferably, the pump also includes a housing assembly, which comprises components such as a pump casing, pump cover, sealing ring, water baffle ring, and bearing housing. These components are connected together by fasteners such as bolts and nuts, and simultaneously support the water-proof sleeve, heat dissipation base cover, PCBA, and rear cover. The housing assembly protects the internal structure of the pump from interference and damage from the external environment, while supporting and fixing the internal components. The flow channels inside the pump casing can guide the fluid to move in the required direction, ensuring that the fluid can smoothly enter and leave the pump, thus improving the practicality of the equipment.

[0008] Preferably, it also includes a water-proof sleeve, which is made of corrosion-resistant and high-temperature-resistant material. The water-proof sleeve is fixed to the corresponding position of the water pump by means of bolts or glands. During the operation of the housing assembly, the water-proof sleeve effectively prevents the coolant from direct contact with the sensitive internal components of the water pump, thereby protecting these components from corrosion, wear or other forms of damage and improving the practicality of the equipment.

[0009] Preferably, it also includes a heat dissipation bottom cover, which is provided with 8 corrugated ribs. The ends of the 8 corrugated ribs are tangent to each other to avoid smooth transition, thereby reducing the generation of defects during die casting. The corrugated ribs and the inner corrugated groove increase the contact area between the heat dissipation bottom cover and the coolant, reduce the phenomenon of resistance to expansion and contraction of the casting, stress concentration during the pouring, heat treatment and correction processes, and improve the practicality of the equipment.

[0010] Preferably, it also includes a PCBA, on which a circuit board is mounted, and various electronic components and wiring are respectively mounted on the circuit board; through integrated circuit design and intelligent control algorithms, the PCBA improves the performance and efficiency of the water pump, reduces costs and maintenance costs, enhances the reliability and stability of the water pump, and improves the practicality of the equipment.

[0011] Preferably, it also includes a rear cover, which is installed at the bottom of the housing assembly and is sealed to the housing assembly. The rear cover prevents leakage of the pump medium, ensures the normal operation of the pump, strengthens the structural strength of the pump body, improves the pump's pressure resistance, ensures the stability and safety of the pump during high-speed operation, and improves the practicality of the equipment.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The housing assembly supports the water jacket, heat dissipation bottom cover, PCBA, and rear cover respectively. The equipment is started by activating the housing assembly. During operation, the water jacket isolates the coolant from the key components in the housing assembly. The heat dissipation bottom cover directly contacts the coolant inside the housing assembly. The corrugated ribs and inner corrugated grooves in the heat dissipation bottom cover increase the contact area between the aluminum cover and the coolant. The back of the MOSFETs and MCUs in the PCBA that need heat dissipation is in contact with the aluminum cover through thermal grease. The heat dissipation bottom cover directly contacts the coolant inside the water pump. The heat dissipation bottom cover dissipates heat from the PCBA. The rear cover protects the PCBA, improving the practicality of the equipment. Attached Figure Description

The flow channels inside the pump housing guide the fluid to move in the desired direction, ensuring smooth entry and exit of the fluid. Then, during operation, the water-blocking sleeve 02 effectively prevents direct contact between the coolant and sensitive internal components of the water pump, thus protecting these components from corrosion, wear, or other forms of damage. Next, the corrugated ribs and inner corrugated grooves increase the contact area between the heat dissipation base cover 03 and the coolant, reducing the phenomenon of casting expansion and contraction obstruction, and stress concentration during casting, heat treatment, and correction processes. Then, through integrated circuit design and intelligent control algorithms, the PCBA 04 improves the performance and efficiency of the water pump, reduces costs and maintenance costs, and enhances the reliability and stability of the water pump. Finally, the rear cover 05 prevents leakage of the pump medium, ensuring normal operation of the water pump.
