Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-3, the embodiment of the utility model provides a canned motor pump heat abstractor for give the heat dissipation of the

pump body

1, 1 surface of the pump body is equipped with a plurality of heat dissipation muscle 10 just heat dissipation muscle 10 is along the axis align to grid of the

pump body

1, and 1 top of the pump body sets up

heat dissipation case

2, 2 inner chambers level in the heat dissipation case has arranged back flow 3, back flow 3 is the disc and arranges, and the both ends of back flow 3 all stretch out from heat dissipation case 2, and the one end intercommunication pump body 1 export of back flow 3 and the other end of back flow 3 stretch into the bearing frame department of the

pump body

1, 3 inner walls of back flow are provided with a plurality of radiating fin 30, still be provided with radiator fan 20 on at least one side of heat.

Specifically, the two sides of the heat dissipation box 2 are provided with strip-shaped holes 21, and the bottom ends of the strip-shaped holes 21 are opened so that the heat dissipation box 2 is covered and buckled above the return pipe 3 from top to bottom.

In the scheme, the plurality of radiating ribs 10 are uniformly arranged on the outer surface of the pump body 1, and the radiating ribs 10 are arranged along the axis of the pump body 1, so that the radiating area of the pump body 1 is increased; the return pipe 3 is arranged at the top of the pump body 1, the return pipe 3 is horizontally arranged in a disc shape, the conveying length of liquid in the return pipe 3 is prolonged, the resistance of the liquid in the return pipe 3 is increased, the stay time of the liquid in the return pipe 3 is longer, and the heat dissipation area is effectively increased and the heat of the liquid is quickly dissipated by arranging the plurality of heat dissipation fins 30 in the return pipe 3; set up heat dissipation case 2 in 3 tops of back flow pipe, bar hole 21 is seted up to heat dissipation case 2's both sides, the open size in and bar hole 21 in bar hole 21 and the size looks adaptation of cooling tube in the bottom, make 2 top-down of heat dissipation case cover when placing back flow 3, heat dissipation case 2 is through screw fixed mounting at pump body 1 top, through installing radiator fan 20 on heat dissipation case 2's side, radiator fan 20 exchanges the hot-air in heat dissipation case 2 with external cold air, play refrigerated effect to back flow 3, high heat exchange efficiency, liquid in the back flow 3 enters into pump body 1's bearing frame department after being cooled down, flow back to pump body 1 export again, in cycles and again, fully dispel the heat to pump body 1, the radiating effect is good.

The section of the return pipe 3 is waist-shaped or oval.
