Abstract
A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.
Claims16
A fluid pump comprising:
- a pump element in communication with an inlet and an outlet, wherein rotation of the pump element generates an inward suction at the inlet and outward pressure at the outlet that cooperatively moves a fluid through a fluid path, the pump element having a stator and a rotor within a housing;
- an accessory fluid path in communication with the inlet and the outlet, wherein an orifice directs a portion of the fluid through the accessory fluid path, the accessory fluid path having a low-restriction return path that generates a continuous flow of the fluid through the accessory fluid path during operation of the pump element;
- and
- a circuit board housing having a contoured portion that aligns with one side of an outer wall and the orifice, the circuit board housing having a printed circuit board with a thermistor in communication with the accessory fluid path, wherein:
- the continuous flow is directed between the orifice and the contoured portion and along the one side of the outer wall between the rotor and the outer wall;
- the low-restriction return path and the aligned orifice and contoured portion are configured to maintain a temperature of the continuous flow of the fluid in the accessory fluid path to be similar to a temperature of the fluid in the fluid path;
- and
- the thermistor is positioned in communication with the contoured portion to simultaneously monitor, in real time, the temperature of the continuous flow of the fluid in the accessory fluid path and the temperature of the fluid in the fluid path.

A fluid pump comprising:
- a pump element in communication with a fluid path, the pump element including a rotor and a stator within a housing;
- and
- an orifice in communication with the pump element, wherein the pump element and the orifice generate a primary flow of a fluid that is directed to an outlet and an excess flow of the fluid that is directed through an accessory fluid path that extends between the rotor and one side of an outer wall of the housing, and
- a circuit board housing having a contoured portion that aligns with the one side of the outer wall and the orifice to define a portion of the accessory fluid path;
- wherein
- the accessory fluid path includes a low-restriction return path that moves the excess flow of the fluid as a continuous flow through the accessory fluid path and toward the outlet;
- the low-restriction return path is configured to maintain a temperature of the excess flow of the fluid in the accessory fluid path to be similar to a temperature of the primary flow of the fluid;
- and
- a thermistor is positioned in communication with the contoured portion to simultaneously monitor, in real time, the temperature of the excess flow of the fluid in the accessory fluid path and the temperature of the primary flow of the fluid in the fluid path.
