Abstract
A bypass valve for a heat exchanger including a plurality of parallel tubular members comprises a housing having a hollow plug portion adjacent to an actuator portion. The actuator comprises a reciprocating plunger extending into the plug portion and a solenoid having a central actuator shaft attached to the plunger, wherein the actuator shaft extends upon energization of the solenoid so that the plunger prevents bypass flow through the valve. The valve also comprises a temperature sensor for sensing a temperature of the fluid flowing through the heat exchanger, the temperature sensor being electrically coupled to the solenoid through one or more conductors, wherein the temperature sensor is located at the first end of the actuator shaft and the conductors extend through the hollow interior of the actuator shaft to the second end thereof.
