Described dividing plate is provided with the cooling water channel communicated with described pump head chamber near the side of pump head.
Described dividing plate is provided with outer magnetic ring mounting groove near the side of pump head, and described cooling water channel is between outer magnetic ring mounting groove and outer land.
Described cooling water channel is the enclosed construction with inlet and outlet, and described inlet and outlet lays respectively at water inlet and the both sides of outlet axis projection line in pump head chamber.
Described cooling water channel is loop configuration.
Described outer land is connected by connected structure with motor housing, and described sealing ring is positioned in connected structure.
On dividing plate, the main heating module contact position with panel is provided with diversion channel, and described diversion channel communicates with pump head chamber.
Described dividing plate is aluminium sheet.
The beneficial effects of the utility model are: control module be located between pump head and motor, it is spaced by dividing plate between panel and pump head chamber, coolant in pump head chamber can cool down control module, without separately setting the air-cooled structure communicated with the external world, avoid into water, installation pedestal is sealed by sealing ring with the junction of motor housing, it is achieved to panel and the sealing of motor, improve barrier propterty.
Further, cooling water channel is set on front side of dividing plate, coolant is played guide functions, it is possible to cool down for panel.
Further, the inlet and outlet of cooling water channel lays respectively at water inlet and the both sides of outlet axis projection line in pump head chamber, when the impeller in pump head starts running, pressure differential will be there is between inlet and outlet, the coolant promoting pump head intracavity forms flowing by cooling water channel, thus improves cooling effectiveness.
