Description
Technical field
The utility model relates to a kind of LNG cold energy recovery system, relates to a kind of commercial refrigeration car LNG cold energy recovery system in particular, belongs to commercial vehicle engine System design technology field.
Background technology
At present, LNG(liquefied natural gas) be widely used on commercial vehicle/comm..vehicle, and when LNG uses as motor vehicle fuel, need the cryogenic liquid from-160 DEG C to expand gasification to gas at normal temperature.Existing commercial refrigeration car, its refrigeration relies on the way refrigeration of similar air-conditioning; Simultaneously, the driving engine of commercial refrigeration car adopts LNG to make fuel mostly, specifically see Fig. 2, LNG enters carburetter 4 from LNG fluid reservoir 5, the refrigerant fluid of refrigerant fluid water tank 7 is entered by electric water pump 6 and carries out heating to LNG in carburetter 4 to make LNG be vaporized device 4 heat vaporized, and the LNG after heat vaporized becomes the gaseous natural gas that can directly utilize for driving engine and enters in driving engine; The cold energy of LNG is cooled after water absorbs and has directly got back in refrigerant fluid water tank 7, is finally brought in air by the cooling system of driving engine.Therefore, LNG has the cold energy of considerable part taken away by driving engine or directly entered in air, is not utilized; Meanwhile, the cold energy that van cooler needs is provided by independent refrigeration system, thus causes a large amount of cold energy wastes.
Summary of the invention
The purpose of this utility model is that the LNG cold energy of commercial refrigeration car is not utilized, causes the problems such as a large amount of cold energy wastes, provides a kind of commercial refrigeration car LNG cold energy recovery system.
for achieving the above object, technical solution of the present utility model is:a kind of commercial refrigeration car LNG cold energy recovery system, comprise refrigerator carriage, carburetter, LNG fluid reservoir and refrigerant fluid water tank, circulating fan is provided with in described refrigerator carriage, described LNG fluid reservoir is connected with carburetter natural fuels channel entrance, described carburetter natural fuels channel outlet is connected with driving engine, described refrigerant fluid water tank is connected with carburetter cooling liquid inlet by electric water pump, radiator is provided with in described refrigerator carriage, described heat sink inlet is connected with carburetter cooling liquid outlet, radiator outlet is connected with refrigerant fluid water tank, the position of radiator is corresponding with circulating fan.
compared with prior art, the beneficial effects of the utility model are:
Structure is simple, achieves the recovery of commercial refrigeration car LNG cold energy, reduces the burden of van cooler.Be provided with radiator in refrigerator carriage in the utility model, heat sink inlet is connected with carburetter cooling liquid outlet, and radiator outlet is connected with refrigerant fluid water tank, and the position of radiator is corresponding with circulating fan; Enter radiator from carburetter cryogenic liquid out, circulating fan blows radiator, thus LNG cold energy has been stayed in refrigerator carriage, solves the cold energy waste problem of commercial refrigeration car LNG, decrease the consumption of power of van cooler, and then reduce oil consumption.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is existing commercial refrigeration car LNG vaporization structural representation.
In figure, refrigerator carriage 1, radiator 2, circulating fan 3, carburetter 4, LNG fluid reservoir 5, electric water pump 6, refrigerant fluid water tank 7.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be described in further detail.
See Fig. 1, a kind of commercial refrigeration car LNG cold energy recovery system, comprises refrigerator carriage 1, carburetter 4, LNG fluid reservoir 5 and refrigerant fluid water tank 7.Circulating fan 3 is provided with in described refrigerator carriage 1, described LNG fluid reservoir 5 is connected with carburetter 4 natural fuels channel entrance, described carburetter 4 natural fuels channel outlet is connected with driving engine, and described refrigerant fluid water tank 7 is connected with carburetter 4 cooling liquid inlet by electric water pump 6.Be provided with radiator 2 in described refrigerator carriage 1, described radiator 2 import is connected with carburetter 4 cooling liquid outlet, and radiator 2 outlet is connected with refrigerant fluid water tank 7; The position of radiator 2 is corresponding with circulating fan 3, for being sucked in refrigerator carriage 1 by cold energy.
See Fig. 1, during work, LNG enters carburetter 4 from LNG fluid reservoir 5, and simultaneously electric water pump 6 pumps into refrigerant fluid and carries out heating to LNG in carburetter 4 to make LNG be vaporized device 4 heat vaporized from refrigerant fluid water tank 7, achieves the thermal exchange between LNG and refrigerant fluid; LNG after heat vaporized becomes the gaseous natural gas that can directly utilize for driving engine and enters participation burning work done in driving engine.Refrigerant fluid is by becoming cryogenic liquid after carburetter 4 heat release, and this cryogenic liquid enters in radiator 2, and circulating fan 3 pairs of radiatores 2 blow, and realizes the air in refrigerator carriage 1 and the thermal exchange in radiator 2; The cold energy of LNG is absorbed rear refrigerant fluid have been got back in refrigerant fluid water tank 7, thus LNG cold energy has been stayed in refrigerator carriage 1, achieves the recovery of LNG cold energy, and then achieves the refrigeration of refrigerator carriage 1.And due to radiator 2, to be arranged on refrigerator carriage 1 inner, and it directly carries out interchange of heat with air of refrigerator carriage 1, and cold energy loss is lacked, and good refrigeration effect, by this cold energy recovery system, can reduce the power consumption of van cooler 3 ~ 5KW, save the energy.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, said structure all should be considered as belonging to protection domain of the present utility model.
