5kw water parking heater

diesel coolant heaterIntroduction

The main motor of the water parking heater drives the plunger oil pump, the combustion air fan and the atomizer to rotate. The oil pump sends the sucked fuel to the atomizer through the oil pipeline. The atomizer atomizes the fuel and the air sucked by the combustion-supporting fan is mixed in the main combustion chamber by the centrifugal force, and is ignited by the hot glow plug, which is fully occupied in the rear combustion chamber. After burning, the heat is transferred back to the inner wall of the water jacket and the heat sink above, and the heat is transferred to the medium in the water jacket interlayer – the coolant. After heating, the medium circulates through the entire pipeline system under the action of circulating water pump (or heat convection) to achieve the purpose of heating. The exhaust gas burned by the heater is discharged by the exhaust pipe.


Application of 5kw water parking heater

  1. Start at low temperature for various vehicle engines.
  2. Provide heat source for windshield defrosting and interior heating


Heating the circulating medium of the automobile engine – antifreeze, directly transferring the heat to the radiator and defroster in the car, providing a heat source for the engine to start at low temperature and to warm the interior of the vehicle.
