Description

On-board parking heating system

technical field

The utility model patent relates to the field of vehicle heating systems, in particular to a parking heating system.

Background technique

At present, the domestic caravan market is developing day by day, but there is no unified solution to the comfort problems of heating and hot water brought along with it. The methods generally adopted by OEMs are gas heating and engine reheating heating. These two methods have the following advantages and disadvantages: the gas heating speed is faster, and it can realize instant heating, but the gas tank needs to be added with the car, occupying the space of the living area, and there are potential safety hazards; convenient. The engine hot water recovery heating is directly heated by the engine coolant, which has the advantages of no additional heat source, simple and easy implementation of the system, and no need to occupy space in the car, but the heating function cannot be realized when parking.

Contents of the invention

The technical problem to be solved by the utility model is to provide a vehicle-mounted parking heating system. The parking heating system uses the vehicle's own fuel to heat the engine coolant to realize circulating heating. Solve the problem of difficult engine cold start in winter, and can provide engine preheating function, hot water/heating for functional vehicles such as RVs.

The utility model is realized in the following way: a vehicle-mounted parking heating system includes an engine, a fuel heater assembly, a heat exchanger, a rear heater and a fuel tank, and the fuel inlet of the fuel heater assembly is connected through an oil inlet pipeline. To the fuel tank, the coolant circulation pipeline of the engine is connected in sequence as engine -> fuel heater assembly -> heat exchanger -> rear heater -> engine.

A water pump is arranged on the coolant inlet pipeline of the fuel heater assembly.

An oil pump is connected to the oil inlet pipeline of the fuel heater assembly.

The fuel heater assembly includes a heater body, the heater body is installed on the heater bracket, the air intake muffler is arranged on the air inlet of the fuel heater assembly, and the exhaust port of the fuel heater assembly is arranged There is an exhaust muffler, and the oil inlet pipe of the fuel heater assembly is connected to the oil outlet pipe of the fuel tank through the oil pump.

The vehicle-mounted parking heating system of the utility model utilizes the vehicle's own fuel to heat the engine coolant to realize circulating heating, has a simple structure, is convenient to operate, and has generalizability. Hot water/heating for functional vehicles such as RVs.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content of the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

Example 1

As shown in Figure 1, a vehicle parking heating system includes an engine 1, a fuel heater assembly 2, a heat exchanger 3, a rear heater 4 and a fuel tank 5, and the fuel inlet of the fuel heater assembly 2 passes through The oil inlet pipeline is connected to the fuel tank 5, and the coolant circulation pipeline of the engine 1 is connected sequentially as engine 1->fuel heater assembly 2->heat exchanger 3->rear heater 4->engine 1.

In the utility model, in order to realize the supply of the oil circuit and the circulation of the coolant, a water pump 6 is provided on the coolant inlet pipeline of the fuel heater assembly 2; There are oil pumps7.

When working, the fuel heater assembly 2 works through the water pump, sucking the coolant from the engine 1 into the fuel heater assembly 2, after heating, it flows through the heat exchanger 3, and the domestic water inside the heat exchanger 3 is cooled Heating to realize the function of domestic hot water; after that, the coolant enters the rear warm air 4 to realize the function of parking warm air.

As shown in Figure 2, the fuel heater assembly 2 includes a heater body 21, the heater body 21 is installed on a heater bracket 22, and an air inlet muffler 23 is arranged on the air inlet of the fuel heater assembly , the exhaust port of the fuel heater assembly is provided with an exhaust muffler 24, and the oil inlet pipe 25 of the fuel heater assembly 2 is connected to the oil outlet pipe 51 of the fuel tank 5 through the oil pump 7; during operation, the fuel in the fuel tank 5 passes through The oil outlet pipe 51 is pumped into the fuel heater assembly 2 by the oil pump 7, where combustion occurs inside the fuel heater assembly 2 to generate heat; the combustion waste gas is filtered by the exhaust muffler 24 and discharged into the air.

As shown in Figure 3, under the parking condition, the working principle of the coolant circulation is: the water pump 6 is used as the power supply for the coolant circulation to push the coolant to circulate inside the pipeline; the coolant enters from the outlet of the engine 1 through the pipeline The water pump 6, after being heated in the fuel heater assembly 2, flows into the heat exchanger 3 to heat the domestic water in the heat exchanger 3 to realize domestic hot water; after the coolant exits the heat exchanger, it is cooled The liquid continues to enter the rear heater 4 to heat the air in the rear heater 4 to realize parking heating; finally, the coolant coming out of the rear heater 4 flows back to the return pipe of the engine 1, passes through the engine, and returns to the engine. Engine 1 water outlet to complete the cycle.
