Vehicle-mounted fuel oil heating system with stepless adjustable heat capacity

Abstract

The invention discloses a vehicle-mounted fuel oil heating system with stepless adjustable heating capacity, and relates to the technical field of vehicle-mounted fuel utilization. The system comprises a water heating fuel oil heating component, a heat storage heat release component, a solution tank, a water-liquid heat exchanger and a gas-liquid heat exchanger; the water heating fuel oil heatingcomponent comprises an oil pump, a water heating fuel oil heater and a water pump; the heat storage heat release component comprises a heat storage coil pipe and a heat release coil pipe; the heat storage coil pipe and the heat release coil pipe are arranged in a heat exchange box; and the heat exchange box is filled with a phase change heat medium. According to the vehicle-mounted fuel oil heating system, by reasonably controlling and switching the flowing of solution between a fuel oil heater and a heat storage tank, the problem that the heater is frequently started and stopped to adapt to the working condition of extremely high and extremely low heating load is solved, and meanwhile, the service life of the fuel oil heater is effectively prolonged, and the vehicle-mounted fuel oil heating system has relatively high market application value.

Description

Technical field [0001] The invention belongs to the technical field of vehicle fuel utilization, and particularly relates to a vehicle fuel heating system with infinitely adjustable heating capacity. Background technique [0002] With the improvement of people's living standards, RVs have gradually entered the public eye. In the process of living in the wild, there is a need to blow warm air in the carriage and provide hot water for daily use such as showers. If you rely solely on electric heating, due to the limited space on the vehicle, to meet the long-term electricity demand in the field, the volume and weight of the battery need to be increased, and the cost will also be greatly increased. Using the fuel-fueled generator set alone, the energy has been converted many times, the utilization rate is low, and the cost is high. From the perspective of space, investment cost and ease of use, fuel heaters are a good choice. [0003] According to the different heat transfer media, ...

AI Technical Summary

Problems solved by technology

At present, the heating capacity adjustment range of fuel oil heaters has a certain limit. Different operating conditions of warm air and domestic hot water have different demands on heating capacity. Relying on the fuel heater itself to adapt to this load change will cause its frequent start and stop, which will affect its reliability and reduce its service life after a long time; if multiple fuel heaters with small heating capacity are selected, by controlling their start and stop To adapt to the change of heating load, it will increase the complexity of pipeline layout and electrical control, and also increase the risk of leakage, and it is impossible to realize the stepless adjustment of heating capacity from 0 to 100%.
