A hydrodynamic heater includes an inlet port for receiving a stream of fluid from an external source and an outlet port for discharging a stream of heated fluid from the hydrodynamic heater. A hydrodynamic chamber operates to selectively heat fluid present within an interior region of the hydrodynamic chamber. The hydrodynamic chamber includes an inlet port and an outlet port located along an interior wall of the hydrodynamic chamber. The hydrodynamic chamber inlet port is fluidly connected to the inlet port of the hydrodynamic heater. The hydrodynamic heater includes a fluid metering device having an inlet fluidly connected to the hydrodynamic heater inlet port and an outlet fluidly connected to the inlet port of the hydrodynamic chamber.

A vehicle heating/cooling system has first and second fluid circulation loops for circulating engine coolant and automotive fluid. A first heat exchanger transfers heat from the coolant to air for the passenger compartment. A second heat exchanger transfers heat between the coolant and automotive fluid. A first valve has first and second inlets for receiving coolant from hot and cold coolant sources, and an outlet for discharging coolant to the second heat exchanger. A second valve has an inlet for receiving coolant from the first coolant source, and an outlet for discharging coolant to the first inlet of the first valve. The valve positions change with temperature of the coolant and the automotive fluid, providing preferential heating of the passenger compartment during cold start-up of the vehicle. The second heat exchanger and valves may be provided in a temperature control module.

A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.

A hydrodynamic heater pump may include a housing and a stator fixed relative to the housing. A rotor may be coaxially aligned with and positioned adjacent the stator. The rotor and the stator define an interior region of a hydrodynamic chamber operable for heating a fluid present within the interior region of the hydrodynamic chamber. The rotor may be attached to a drive shaft for concurrent rotation therewith. The rotor may be moved axially along an axis of rotation of the drive shaft between a pumping mode position and a heating mode position. The rotor may be located a first distance from the stator when arranged in the heating mode position and a second distance from the stator when arranged in the pumping mode position. The second distance may be greater than the first distance.

A mobile heating system includes an enclosure defining a plenum that houses a fan and an internal combustion engine. The heating system also includes a hydraulic circuit including a hydraulic pump operably coupled to the internal combustion engine and a first heat exchanger located in the plenum and in fluid communication with the hydraulic pump.
