The purpose of this utility model is at the deficiencies in the prior art, has proposed a kind of energy savings, and is fuel-efficient, economic for motor vehicle fridge equipment.

The purpose of this utility model reaches by the following technical programs, a kind of refrigerating apparatus for vehicles, comprise and drive refrigerant at system's interior orientation flow air compression set, flow direction by refrigerant is loaded on vehicle water tank fwd condenser with plumbing connection successively, the filtration drying reservoir, heating power expansion valve, be contained in the evaporator in the operator's compartment, be characterized in: described air compression plant comprises the H Exch that is installed in automotive engine and eduction pipe connecting portion and be installed near the H Exch two-way blower fan under power supply on vehicle drives, on the outlet conduit of compression set, be provided with the outgassing nonreturn valve of only export but no import, on the inlet pipeline of compression set, be provided with the breather check valve of only import but no export.Two-way blower fan is just changeing the heat of absorption from freeing pipe, thereby hot vapour is heated H Exch through over-heat-exchanger, its internal refrigeration storage agent is expanded, internal pressure raises, after reaching certain pressure, wash out the vapour check valve open, the part refrigerant is rushed in condenser, till equilibrium of pressure, go out the vapour closed check valve; The refrigerant that enters condenser is under the control of heating power expansion valve, and in the condenser of delay, because the continuous rising of pressure, the part condensation of refrigerant is liquid, emits heat; When reaching certain pressure, the refrigerant in the condenser is washed heating power expansion valve open, enters evaporator, because pressure reduces suddenly, the refrigerant that enters evaporator becomes gaseous state by liquid state, absorbs heat, then realizes the refrigeration purpose; Blow normal temperature air with two-way blower fan counter steer H Exch again, make cools down, then the agent of H Exch internal refrigeration storage is shunk, pressure reduces, and evaporator internal pressure height is then opened the admission check valve, the part refrigerant enters H Exch in the evaporator, till pressure reaches balance; Jian Ge heating, cooling heat exchanger promote the refrigerated medium cryogen and constantly make directed flow in systems like this, the condenser heat radiation, and the evaporator heat absorption, evaporator is contained in the operator's compartment, thereby realizes the purpose of refrigeration.The utility model utilizes the used heat of engine exhaust, promotes refrigerant through H Exch and circulates in system, thereby reach the purpose of refrigeration, and it drives without the power of driving engine, thereby has saved fuel, and is economical and practical.

The purpose of this utility model can also come further to reach by the following technical programs, is provided with discharging refrigerant alternately around automobile exhaust pipe, sucks the two groups of Hs Exch and the two-way blower fan of refrigerant.Replace discharging refrigerant, suck refrigerant by two groups of Hs Exch, can reach continuous cooling, improve the degree of utilization of freeing pipe used heat, increase refrigeration.

The purpose of this utility model can also come further to reach by the following technical programs, and described check valve is mechanical type check valve or electromagnetic valve.The switch of the directed control electromagnetic valve of the difference of pressure by two ends, safety performance is good.

Compared with prior art, the utility model utilizes the used heat of engine exhaust, promotes refrigerant through H Exch and circulates in system, thereby reach the purpose of refrigeration, and it drives without the power of driving engine, thereby has saved fuel, and is economical and practical.Two Hs Exch that replace discharging refrigerant, suction refrigerant are set further improve the degree of utilization of freeing pipe used heat, strengthen refrigeration.

Fig. 1 is the utility model circulating system structural representation.

Fig. 2 is two thermoconverters and two two-way blower fans and eduction pipe position view.

Below in conjunction with accompanying drawing specific embodiments of the present utility model is further described.

Embodiment one, the specific embodiment of the present utility model as shown in Figure 1, a kind of refrigerating apparatus for vehicles, comprise and drive refrigerant at system's interior orientation flow air compression set, the flow direction of pushing the contraction cryogen is loaded on vehicle water tank fwd condenser 4 with plumbing connection successively, filtration drying reservoir 5, heating power expansion valve 6, be contained in the evaporator 7 in the operator's compartment, described air compression plant comprises the H Exch 2 that is installed in automotive engine and eduction pipe 9 connecting portions and be installed near the H Exch two-way blower fan 1 under power supply on vehicle drives, on the outlet conduit of compression set, be provided with the mechanical type check valve 3 of giving vent to anger of only export but no import, on the inlet pipeline of compression set, be provided with the air inlet mechanical type check valve 8 of only import but no export.Two-way blower fan 1 is just changeing the heat of absorption from freeing pipe, thereby hot vapour is heated H Exch 2 through over-heat-exchanger 2, its internal refrigeration storage agent is expanded, internal pressure raises, after reaching certain pressure, wash out vapour check valve 3 open, the part refrigerant is rushed in condenser 4, till equilibrium of pressure, go out vapour check valve 3 and close; The refrigerant that enters condenser 4 under the control of heating power expansion valve 6,4 li of the condensers of delay because the continuous rising of pressure, the part condensation of refrigerant be a liquid state, emits heat; When reaching certain pressure, the refrigerant in the condenser is washed heating power expansion valve 6 open, enters evaporator 7, because pressure reduces suddenly, the refrigerant that enters evaporator 7 becomes gaseous state by liquid state, absorbs heat, then realizes the refrigeration purpose; Blow normal temperature air with two-way blower fan 1 counter steer H Exch 2 again, make H Exch 2 coolings, then H Exch 2 internal refrigeration storage agent are shunk, pressure reduces, and evaporator 7 internal pressure height are then opened admission check valve 8, the part refrigerant enters H Exch 2 in the evaporator 7, till pressure reaches balance; Jian Ge heating, cooling heat exchanger promote the refrigerated medium cryogen and constantly make directed flow in systems like this, thereby realize the purpose of refrigeration.The utility model utilizes the used heat of engine exhaust, promotes refrigerant through H Exch and circulates in system, thereby reach the purpose of refrigeration, and it drives without the power of driving engine, thereby has saved fuel, and is economical and practical.
