Description
Technical field
The utility model belongs to on-board air conditioner technical field, and in particular to utilizes the on-board air conditioner of fuel cell waste heat.
Background technique
In the prior art, on-board air conditioner is heated under heating condition in winter by heat pump effect, when environment temperature is too low,
On-board air conditioner is using the integrated PTC electric heating auxiliary heating with inside air-conditioning, and working principle is as shown in Figure 1, in refrigerant pipeline
Refrigerant is converted into high-pressure gaseous after passing through compressor, and heat release becomes liquid within the condenser, this partial heat is by the sky in air-conditioning
The gas circulatory system is transmitted to passenger compartment；When winter environment temperature is too low (< -5 DEG C), heat pump effector function is limited, needs to pass through
PTC electric heating auxiliary heating, PTC electric heating directly heat air, and hot-air equally passes through air circulation system and blows to passenger compartment,
To play heating passenger compartment purpose.But existing on-board air conditioner heats (compressor and PTC electric heating) simply by power consumption, especially
Its PTC electrical heating efficiency is low, is big consuming components；And existing thermal management scheme does not utilize fuel battery waste heat (remaining
Heat), cause vehicle that can only warm oneself by air-conditioning, hot-water heating or electric heating radiator, a large amount of electricity can be expended, improves vehicle energy consumption
With reduction vehicle continual mileage.
Utility model content
The purpose of this utility model is to provide a kind of on-board air conditioners using fuel cell waste heat.For solving existing vehicle
Carrying air-conditioning does not utilize vehicle fuel cell waste heat to warm oneself, and causes the problem of increasing vehicle energy consumption.
In order to solve the above technical problems, the technical solution of the utility model are as follows:
A kind of on-board air conditioner using fuel cell waste heat, including condenser, compressor, condenser, compressor pass through cold
Matchmaker's pipeline constitutes circulating path；It further include a fuel cell heat sink, fuel cell heat sink passes through coolant line and combustion
Expect battery connection, fuel cell heat sink is mounted in the air circulation system of on-board air conditioner or integrates with condenser.
The utility model has the beneficial effects that
The utility model by utilizing fuel battery waste heat in winter, by the way that fuel cell heat dissipation is added in on-board air conditioner
The air circulation system of device, on-board air conditioner blows air over spreader surface, takes away the heat of fuel cell coolant liquid, utilizes combustion
Material battery waste heat is Vehicle heating, solves existing on-board air conditioner and vehicle fuel cell waste heat is not utilized to warm oneself, and causes to add
The problem of big vehicle energy consumption.
It further, further include the valve for controlling refrigerant pipeline.
Further, evaporator is additionally provided in circulating path.
Detailed description of the invention
Fig. 1 is the heating schematic diagram of prior art on-board air conditioner；
Fig. 2 is the schematic diagram of embodiment.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawings and embodiments, to this
Utility model is described in further detail.
The basic principle of the utility model are as follows:
The utility model by utilizing fuel battery waste heat in winter, by the way that fuel cell heat dissipation is added in on-board air conditioner
Device, fuel cell heat sink are mounted in the air circulation system of on-board air conditioner or integrate with condenser.On-board air conditioner
Air circulation system blow air over spreader surface, take away the heat of fuel cell coolant liquid, utilize fuel cell waste heat
For Vehicle heating.Air can blow into passenger compartment after heating, play the role of heating passenger compartment.
As shown in Fig. 2, on-board air conditioner part: the refrigerant pipeline of the outlet connect compressor of the refrigerant pipeline of evaporator enters
Mouthful, the entrance of the refrigerant pipeline of the outlet connection condenser of the refrigerant pipeline of compressor, the outlet of the refrigerant pipeline of condenser leads to
The entrance of the condenser pipe of throttle valve connection evaporator is crossed, above-mentioned device constitutes circulating path by refrigerant pipeline.
Fuel cell has the heat dissipation path of itself in figure, controls the refrigerant pipeline entrance of fuel cell heat sink
Valve as shown is triple valve, the entrance of fuel cell refrigerant pipeline outlet connection triple valve；Fuel cell self-radiating device
Circulating path is constituted using the outlet 1 of triple valve by refrigerant pipeline with fuel cell, in the outlet 2 of triple valve and on-board air conditioner
Radiator pass through refrigerant pipeline connect.Because containing more heat in fuel cell coolant liquid, air-conditioning inner radiator can only
Using a part, remaining heat also needs to dissipate by the cooling system of fuel cell itself, so the heat dissipation of on-board air conditioner
The entrance of the coolant line of the radiator of the outlet connection fuel cell of the coolant line of device, constitutes another the circulation path
Diameter.Above-mentioned two circulating paths are switched over by triple valve.
Hot gas after heating is blown into passenger compartment by the air circulation system inside air-conditioning.
In winter in the lower situation of temperature, by opening the outlet 2 of triple valve, pass through the coolant liquid of fuel cell cold
But liquid pipeline enters on-board air conditioner, and the air circulation system inside air-conditioning blows air over air-conditioning inner radiator surface, carries out the
Primary heating can also blow over the condenser surface of heat pump air conditioner if air themperature is not high at this time again, carry out second and add
Heat, air can blow into passenger compartment after heating twice, play the role of heating passenger compartment.
If do not need on-board air conditioner heating, the outlet 2 of triple valve is closed, 1 conducting of outlet；The coolant liquid of fuel cell is logical
Supercooling liquid pipeline is passed through the radiator of fuel cell itself, and fuel cell is radiated using the heat dissipation circulating path of itself.At this point,
Fuel cell coolant liquid belongs to fuel cell and normally cools down without air-conditioning.
As other embodiments, the ptc heater in the present embodiment in on-board air conditioner is removed, in ptc heater position
Upper device is used for the radiator of fuel cell heat dissipation.
As other embodiments, fuel cell heat sink and electric heater can be used cooperatively, be together Vehicle heating.
As other embodiments, fuel cell heat sink may be mounted at the air circulation in the vehicle air circulatory system
In channel or near device and air circulation duct, it is connect with air circulation duct.
As other embodiments, the valve for controlling the refrigerant pipeline entrance of fuel cell heat sink is that can reach switching
Other devices substitution of circulating path effect.
It is discussed in detail although the content of the utility model has passed through above preferred embodiment, but it should be appreciated that on
The description stated is not considered as limitations of the present invention.After those skilled in the art have read above content, for
A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the protection scope of the utility model should be by appended
Claim limit.
