Technical Field

[0001] The utility model relates to the field of heat dissipation devices for shielded pumps, and more specifically to a heat dissipation device for high-temperature resistant shielded pumps. Background Art

[0002] The canned motor pump in the prior art dissipates heat by connecting the return pipe between the pump body outlet and the bearing seat end of the pump body, and utilizing liquid return to dissipate heat. The return pipe is a straight pipe, which has a small heat dissipation area and low heat exchange efficiency, thus resulting in poor heat dissipation capacity of the canned motor pump.

[0003] In the prior art, CN212177516U provides a shielded pump heat dissipation device for dissipating heat from a pump body, wherein the outer surface of the pump body is provided with a plurality of heat dissipation ribs and the heat dissipation ribs are evenly arranged along the axis of the pump body, a heat dissipation box is provided on the top of the pump body, and a return pipe is horizontally arranged in the inner cavity of the heat dissipation box, and the return pipe is arranged in a disc shape, and both ends of the return pipe extend from the heat dissipation box;

[0004] In the above-mentioned patent, a disc-shaped tube distribution is adopted, and a heat sink is provided with a built-in fan for heat dissipation. The heat dissipation efficiency is low, and the heat dissipation area is small when the liquid is diverted, which affects the heat dissipation efficiency. The pump body itself can only dissipate heat through the heat sink, and the heat dissipation efficiency is low. Utility Model Content

A guide pipe 3 and a return pipe 4 are arranged at the upper end of the shielded pump body 2. A flat guide shell 5 is arranged between the guide pipe 3 and the return pipe 4. The guide portions of the guide pipe 3 and the return pipe 4 are arranged as a conical mouth structure. Both sides of the flat guide shell 5 are arranged with a variable-diameter guide closing structure to change the diameter of the guide when the liquid flows. A first heat sink 6 is arranged on the surface of the flat guide shell 5. A second heat sink 7 is arranged on the outer surface of the shielded pump body 2, and the heat sinks are evenly and densely arranged. An air guide shell 8 is fixed on the outer surface of the shielded pump body 2. A fan 9 is fixedly connected to the outer surface of the air guide shell 8.

[0024] The outer surface of the shielded pump body 2 is fixedly connected with a support rib 10, and the outer end surface of the support rib 10 is fixedly connected to the inner surface of the air guide shell 8, so as to facilitate the support and fixation of the air guide shell 8 and maintain stability;

The flat guide shell 5, the guide pipe 3 and the return pipe 4 are made of brass. The width of the flat guide shell 5 is ten centimeters and the length is not less than thirty centimeters.
