Thermistor flow 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 inlet orifice in communication with the pump element, wherein the pump element and the inlet orifice direct a primary flow of a fluid to an outlet and an excess flow of the fluid into an accessory fluid path having a portion that extends between the rotor and an outer wall of the housing, and
• a circuit board housing having a contoured portion that aligns with one side of the outer wall;
• 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 an outlet orifice;
• the low-restriction return path is configured to maintain a temperature of the excess flow of the fluid in the contoured portion of 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.

A fluid pump comprising:

• a stator and rotor in electromagnetic communication and disposed within a housing;
• a pump element attached to a first end of a drive shaft of the rotor;
• and
• an inlet orifice in communication with the pump element that diverts a primary flow of a fluid to an outlet and an excess flow of the fluid through the inlet orifice and into an accessory fluid path;
• an outlet orifice in communication with the pump element, the outlet orifice directing excess fluid from the accessory fluid path to a primary fluid path;
• and
• a circuit board housing positioned at a second end of the drive shaft that opposes the first end, the circuit board housing having a contoured portion that aligns with one side of an outer wall of the housing;
• wherein
• the accessory fluid path directs the excess flow of the fluid along a linear path directly from the inlet orifice to the contoured portion;
• 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 orifice;
• the low-restriction return path is configured to maintain a temperature of the excess flow of the fluid in the contoured portion of 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 a fluid path.
