Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
As shown in Figure 2, the present embodiment provides a kind of engine air inlet tube line cooling system, and described engine charge pipeline is provided with the parts such as turbosupercharger 4, intercooler 3, motor 1, and the waste gas that wherein power of turbosupercharger 4 is discharged by motor 1 provides.Turbosupercharger 4 is divided into exhaust gas turbine and air inlet turbine, motor 1 tail gas promotes after exhaust gas turbine is rotated to discharge from outlet pipe, between exhaust gas turbine and air inlet turbine, rely on transmission shaft to link, exhaust gas turbine drives air inlet turbine to be rotated, to realize the object that extracts ambient air, and be connected with motor 1 by gas-entered passageway 2.Described engine air inlet tube line cooling system comprises: intercooler 3, is arranged on engine charge pipeline; Intercooler cooling line 10, described intercooler cooling line 10 is connected on automotive air conditioning system pipeline 9.Automotive air conditioning system pipeline 9 is provided with the parts such as compressor 6, condenser 7, expansion valve 8, vaporizer 11.Wherein, compressor 6 power are provided by motor 1, and compressor 6 links by transmission device 5 and motor 1, and the medium in air-conditioning system is refrigeration agent, realizes heat absorption and the heat release of air-conditioning by the phase transformation of refrigeration agent.Compressor 6, by compressing the gaseous state low-temperature refrigerant of discharging from vaporizer 11, changes the refrigeration agent of gaseous state high temperature into by compressed action.The circulation passage that condenser 7 is refrigeration agent carries out heat exchange with ambient air in circulation, and ambient air is taken away heat unnecessary in refrigeration agent, and the high-temperature gas refrigeration agent that compressor 6 is flowed out is converted to the refrigeration agent of high-temperature liquid state.Expansion valve 8 is divided into two spaces of size, and centre connects by capillary tube, and the high-temperature liquid state refrigeration agent that condenser 7 is flowed out enters large space by little space by capillary tube, and refrigeration agent completes greatly the transformation of low pressure and low temperature by the unexpected change of volume.Then, vaporizer 11, as the circulation passage of refrigeration agent, is placed in operator cabin.The refrigeration agent of the low-temp low-pressure that expansion valve 8 flows out, when through vaporizer 11, carries out heat exchange with the hot air in operator cabin, absorbs the heat in operator cabin, plays and reduces the object of driving room temperature.The refrigeration agent of vaporizer 11 of flowing through is low-temp low-pressure state.Described intercooler cooling line 10 is in parallel with the vaporizer 11 on described automotive air conditioning system pipeline 9, and making the refrigeration agent in low-temp low-pressure is the High Temperature High Pressure air heat-exchange in intercooler by intercooler cooling line.Described refrigeration agent adopts R134 refrigeration agent (hydrofluorocarbons compound).Thereby automotive air-conditioning system provides a stable cooling source for intercooler.
Further, described intercooler cooling line 10 is through described intercooler 3, and the refrigeration agent in this intercooler cooling line 10 is by the High Temperature High Pressure air heat-exchange in heat exchange structure and this intercooler 3 in described intercooler 3.Particularly, described automotive air conditioning system pipeline 9 is provided with the first three-way valve at the entrance point of described vaporizer 11, and is provided with the second three-way valve at the outlet end of described vaporizer 11; One end of described intercooler cooling line 10 is connected with described the first three-way valve, and the other end of this intercooler cooling line 10 is connected with described the second three-way valve.By analyzing, can increase the refrigerant flow in automotive air conditioning system pipeline 9, by described intercooler cooling line 10 these loops, realize the cooling of High Temperature High Pressure air in intercooler, replace extraneous wind to realize heat exchange with the refrigeration agent of automotive air-conditioning system.Like this, even if automobile exists in the situation of heat exchange lack of air in intercooler in the time of hot environment or idling mode, still can effectively reduce the temperature of engine charge.Under normal circumstances, due to the vaporizer position that the minimum point of car load temperature is automotive air-conditioning system, can under any ambient temperature, realize 10 ℃ and following temperature.Because the temperature of this vaporizer position refrigeration agent is below 10 ℃, can, after abundant heat exchange, Engine Inlet Temperature be reduced to 80～90 ℃, be the power ascension 9%～15% of motor, save fuel oil and reduce environmental pollution.
Because the cooling source of intercooler changes to liquid refrigerant, by the 10 pipeline circulations of intercooler cooling line, can be arranged into each position of car load, behind this position, be convenient to arrangement, intercooler can be arranged into the position near motor, reduce the on-way resistance of intercooler system, the pressure that reduces engine charge changes.
The utility model is by the structural change of intercooler body, allow and flow through intercooler in the refrigeration agent of temperature minimum point, carry out sufficient heat exchange with the High Temperature High Pressure air that flows through intercooler, constant and the temperature of pressure reduces, become cryogenic high pressure air, enter motor and participate in oil inflame, after finishing combustion, tail gas is discharged in atmosphere.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
