With the efficiency improvements heat is generated. The pump also incorporates an aluminium which acts as a heat further easing the heat requirements. The cost of the electric was reduced by using an inexpensive and resistant printed circuit

Background. Controlling the water in engine cooling systems has identified as an effective approach to to reduced fuel consumption. work to develop electric for cooling inverters, Aisin has now focused on automobile cooling

Electric pumps run independently of the speed, which allows control over the water and consequently reductions in fuel

Electric pumps should in the same part of the engine as ones. The main issue in to substitute mechanical pumps electric ones is size. pumps tend to be much in order to achieve the same flow rate.


Aisin Seki tackled a of factors that impinge on the of electric pumps. These enhancements mean that the of their pumps can be decreased. elements affect the overall of the electric pump: the driver, the and the pump itself, which has a low efficiency.

Improving pump efficiency. to the shape of the impeller enabled effective pumping operation. In an operation point that benefits the efficiency of pump and was identified.

The pump is centrifugal. The point that allows efficiency for the motor and pump but a compromise was found.

Economizing on component parts. pumps harness the engine’s through a pump pulley to the engine crank. The rotation of the then drives the pump, is connected to the pulley by a shaft. seals on the shaft prevent of the cooling water.

On the contrary, the pump which is driven by its motor so these seals be eliminated. Resin protects the motor parts from

Cutting costs. The opportunity to on costs was exploited with the use of a print board. Although the resistance may be lower for the cheaper board, the optimized efficiency of the pump reduces the heat

An aluminum enclosure was also which acts as a heat further reducing the level of resistance needed in the print
