Problems solved by technology

[0005] figure 1 The heating cycle in the engine is attached to the cooling cycle of the engine, which has many disadvantages. First, the flow demand of the warm air circuit needs to be considered when selecting the water pump, which increases the power consumption of the water pump; secondly, when the engine is initially started, due to the warm air The heat loss of the circuit (the heat loss phenomenon is especially obvious in cold regions or in winter) leads to longer engine warm-up time and increased fuel consumption; finally, in cold regions or regions with high heating demand in winter, the engine water temperature itself rises slowly, causing occupants The cabin heating effect is poor, and the heating of the passenger compartment leads to low engine water temperature, which also brings a series of adverse damages

Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0028] Such as figure 2 As shown, the motor vehicle heating circulation system of the present invention includes an electronic water pump, and the electronic water pump forms a circulation loop with a gas-liquid heat exchanger and a warm air heater. A cooling liquid is arranged in the circulation loop, and the electronic water pump can drive the cooling liquid to pass through the gas-liquid in turn. Heat exchanger, warm air heater and back to the electronic water pump, the gas-liquid heat exchanger can exchange heat with high-temperatur...

Abstract

The invention discloses a heating circulation system for a motor vehicle. The system comprises an electronic water pump, a gas-liquid heat exchanger and a warm air heater in sequential connection through a connection pipeline, and the electronic water pump, the gas-liquid heat exchanger, the warm air heater and the connection pipeline form a circulation loop which is provided with cooling liquid. The electronic water pump is capable of driving the cooling liquid to sequentially flow through the gas-liquid heat exchanger and the warm air heater to return into the electronic water pump. The gas-liquid heat exchanger can exchange heat with high-temperature motor vehicle tail gas to absorb heat of the high-temperature motor vehicle tail gas. The warm air heater makes use of the heat absorbed by the gas-liquid heat exchanger to supply heat for a passenger compartment. The heating circulation system for the motor vehicle has advantages that warm air heating circulation is independent from an engine cooling system, and accordingly engine warm-up time is shortened, and energy consumption of an engine water pump is reduced; by recovery of motor vehicle exhaust heat for heating of the passenger compartment, waste of exhaust waste heat is reduced, and oil saving of the whole vehicle is realized.

Description

technical field [0001] The invention relates to the technical field of heating circulation systems, in particular to a heating circulation system for motor vehicles. Background technique [0002] Since January 1, 2016, two mandatory national standards, GB 19578-2014 "Limits of Fuel Consumption of Passenger Cars" and GB 27999-2014 "Evaluation Methods and Indicators of Fuel Consumption of Passenger Cars" have been officially implemented. At the same time, in order to implement the requirements of the "Energy Saving and New Energy Motor Vehicle Industry Development Plan (2012-2020)", the average fuel consumption of domestic passenger vehicles in 2020 should be reduced to 5.0L / 100km. It is assessed simultaneously with the average target value of the enterprise. Faced with such stringent fuel consumption regulations, various motor vehicle companies have to research and reserve fuel-saving technologies. [0003] According to statistics on the energy distribution of internal comb...
