Description

Electronic water pump shell
Technical Field
The utility model relates to the technical field of water pumps, in particular to a shell of an electronic water pump.
Background
The electronic water pump is a novel water pump which uses a piezoelectric material as a power device, thoroughly realizes electronization from control to driving, completely controls liquid transmission by an electronic integrated system, and further realizes adjustability and accuracy of liquid transmission.
At present water pump during operation, the electronic components temperature ratio above the circuit board is higher, needs in time to dispel the heat, and traditional water pump shell is the plastics material, and the heat conductivity is not good, and the inside temperature of water pump is difficult for giving off the external world, causes the high damage of components and parts temperature.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides the electronic water pump shell which can greatly reduce the temperature rise of an electronic water pump in a working state and prolong the service life of the water pump.
In order to achieve the purpose, the utility model is realized by the following technical scheme: the shell of the electronic water pump comprises a shell, wherein the inner surface of the bottom of the shell is coated with heat-conducting silicone grease which is connected with a power tube on a circuit board, and the outer surface of the bottom of the shell is additionally provided with a plurality of radiating fins.
Preferably: the radiating fins are rectangular and are evenly distributed on the outer surface of the bottom of the shell.
Preferably: the casing is wholly made of aluminum alloy materials, and the heat dissipation effect is better.
Preferably: the casing is internally provided with a pair of buckles for installing the circuit board, namely a first buckle and a second buckle, the first buckle and the second buckle are arranged in a mutually perpendicular mode, the clamping groove formed in the first buckle is used for clamping the side face of the circuit board, and the clamping groove formed in the second buckle is used for clamping the top or the bottom of the circuit board. Can fix the heating panel through the buckle, the dismouting of being convenient for has changed simultaneously and has reduced installation area of contact, lets the circuit board have more heat dissipation spaces.
Preferably: at least one cooling fan is arranged on one side, located on the circuit board, of the interior of the shell, the cooling fan faces the circuit board, and a plurality of cooling holes are further formed in the outer surface of the bottom of the shell, so that the cooling effect is improved.
Preferably: the shell is in a cylindrical structure.
The utility model has the following beneficial effects:
according to the utility model, the shell is made of aluminum alloy, and the rectangular radiating fins are additionally arranged at the bottom, so that the radiating area of the surface of the shell can be increased, and the temperature in the shell can be effectively conducted to the outside of the shell. The inner surface of the bottom of the shell is coated with heat-conducting silicone grease to be connected with the power tube, and the power tube conducts heat to the shell through the heat-conducting silicone grease and then conducts the heat to the outside air through the radiating fins.

Detailed Description
The preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
The electronic water pump casing as shown in fig. 1-2 comprises a casing 1, wherein the inner surface of the bottom of the casing 1 is coated with heat-conducting silicone grease 2, the heat-conducting silicone grease 2 is connected with a power tube on a circuit board, the outer surface of the bottom of the casing 1 is additionally provided with a plurality of radiating fins 3, and the radiating fins 3 are rectangular and uniformly distributed on the outer surface of the bottom of the casing 1. The whole body of the shell 1 is made of an aluminum alloy material, and the heat dissipation effect is better.
The inside buckle that is equipped with a pair of installation circuit board of casing 1 is first buckle 4 and second buckle 5 respectively, first buckle 4 and second buckle 5 are arranged the direction mutually perpendicular, and the draw-in groove that sets up on the first buckle 4 is used for chucking circuit board side, and the draw-in groove that sets up on the second buckle 5 is used for chucking circuit board top or bottom. Can fix the heating panel through the buckle, the dismouting of being convenient for has changed simultaneously and has reduced installation area of contact, lets the circuit board have more heat dissipation spaces.
At least one cooling fan 6 is arranged on one side, located on the circuit board, of the interior of the shell 1, the cooling fan 6 faces the circuit board, and a plurality of cooling holes 7 are further formed in the outer surface of the bottom of the shell 1, so that the cooling effect is improved.
The casing 1 adopts the aluminium alloy material preparation, and a plurality of rectangle fin 3 of bottom increase can increase the heat radiating area on 1 surperficial of casing, can effectively conduct the casing 1 outside with 1 inside temperature of casing. The inner surface of the bottom of the shell 1 is coated with heat-conducting silicone grease 2 and is connected with a power tube, and the power tube conducts heat to the shell 1 through the heat-conducting silicone grease 2 and then conducts the heat to the outside air through the radiating fins 3.
The above-mentioned embodiments are only used for explaining the inventive concept of the present invention, and do not limit the protection of the claims of the present invention, and any insubstantial modifications of the present invention using this concept shall fall within the protection scope of the present invention.
