Abstract
The utility model provides a cooling capacity recycling heat exchanger of a novel LNG automobile air conditioner. Three layers of barrel bodies are sequentially arranged in a first barrel. A spiral channel is formed outside each barrel body in the first barrel, LNG pipes are matched to be arranged in the spiral channels in the two outer layers, the inside of the barrel body on the innermost layer is used as an LNG evaporation gas chamber, and a porous injection pipe is further arranged. The LNG pipes penetrate out from a second end cover to be changed into LNG outlet pipes which are in series connection with an LNG pipe of the spiral channel of the inner barrel body, and finally the LNG pipes are in series connection to the porous injection pipe and penetrate out from the first end cover at the other end of the barrel body on the innermost layer to be changed into LNG inlet pipes. The first end cover, the second end cover and the spiral channels of the three layers of barrel bodies in the first barrel form a series connection type water return pipeline. A water outlet pipe is arranged outside the first end cover, and a water inlet pipe is arranged outside the second end cover. Formed gas, liquid and coolants are divided into three layers for conducting three-level heat exchange, and thus the large temperature difference heat exchange loss problem is solved. The cooling capacity recycling heat exchanger is simple in structure, economical and practical, thereby being an important component for cooling capacity recycling of the LNG automobile air conditioner.
Description
Technical field
The utility model relates to the parts of liquefied natural gas air conditioning for automobiles, particularly a kind of novel LNG air conditioning for automobiles cold recovery exchanger.
Background technology
LNG liquefied natural gas automobile is because its energy-conserving and environment-protective have started volume production and come into operation, but its air-conditioning still adopts traditional air-conditioning system, traditional air-conditioning system generally adopts freon or 134a to use destruction atmosphere as cold-producing medium, and the high temperature that condenser is discharged 80 degree causes greenhouse effects to be therefore unfavorable for environmental protection.Compressor in traditional air-conditioning system will consume automobile engine 3 horsepowers, improves percent 10 oil consumption.Therefore waste energy.And affect automobile climbing capacity, and under idling mode, reducing refrigeration. liquefied natural gas air conditioning for automobiles is the good project of of energy-conserving and environment-protective, but at present because liquefaction day combustion heat exchanger is also immature. one and neck of the development of liquefied natural gas air conditioning for automobiles become.
The patent No. is 2013200148207 LNG air conditioning for automobiles cold recovery exchanger, although also can address the above problem, but because it is the through hole being longitudinally provided with, in through hole, string has heat exchanger tube, in process, through hole is not easy to realize very much, because heat exchanger tube can only just can be connected by welding at the two ends of through hole, thereby welding heat exchanger tube very easily occurs that trachoma causes the generation of gas leak phenomenon, not only increase welding cost, also increased potential safety hazard.
Summary of the invention
The utility model is in order to save the energy and to be beneficial to environmental protection, and for the uniqueness of air-conditioning system and the chemical functional of LNG, spy proposes a kind of novel LNG air conditioning for automobiles cold recovery exchanger.
For this reason, the technical solution of the utility model is, a kind of novel LNG air conditioning for automobiles cold recovery exchanger,
Comprise cylindrical shell one, the two ends of cylindrical shell one are provided with end cap one, two, it is characterized in that: in cylindrical shell one, be provided with successively three layers of cylindrical shell, wherein in the outside of each interior cylindrical shell, be provided with helical duct, in two-layer helical duct, coordinate and be provided with LNG tracheae outside, wherein in the cylindrical shell of innermost layer, as LNG, evaporate air chamber, and be provided with a porous playpipe; LNG tracheae passes into LNG escape pipe from end cap two, and and the LNG tracheae series winding of inner barrel helical duct, finally contact to porous playpipe, and pass into LNG air inlet pipe from the end cap one of the other end of innermost layer cylindrical shell; Three layers of cylindrical shell helical duct in end cap one, two and cylindrical shell one and cylindrical shell one form an in-line water return pipeline, and wherein the outer outlet pipe that is provided with of end cap one, is provided with water inlet pipe outside end cap two.
Improvement to such scheme is: described cylindrical shell is aluminium alloy casting body; LNG tracheae and porous playpipe are that aluminium alloy or copper pipe are made.
Beneficial effect:
The utility model due to LNG tracheae in the helical duct of aluminium alloy cylindrical body outside in the shape of a spiral, and contact and form with a passage successively outward at end cap, in welding process, will greatly reduce like this quantity of joint, the helical duct of cylindrical shell outside in the process of processing also compared with easy-formation.So just make structure of the present utility model become simple, can suitability for industrialized production, not only saved cost, also guaranteed the quality of product.
The LNG tracheae series connection of three helical layer passage cylindrical shells, the series winding of three helical layer passages, formation gas/liquid and refrigerant are divided into three layers and carry out three grades of heat exchange, have solved large temperature difference heat exchange loss problem; Make LNG evaporation and cast body by aluminium alloy to absorb cold, LNG tracheae in screw type passage becomes the molten liquid runner of ethylene glycol, the center of the cylindrical shell of innermost layer is as air chamber, at the in-built porous LNG porous of air chamber playpipe, ethylene glycol solution carries out reverse flow heat exchange as coolant media and LNG, refrigerant is progressively lowered the temperature after for air conditioning for automobiles driver's cabin refrigeration and other refrigerator refrigeration.
Helical duct forms an in-line water return pipeline, and wherein end cap one is provided with outlet pipe, and end cap two is outer is provided with water inlet pipe, and LNG tracheae forms contrary loop, is conducive to utilize the cold recovery of LNG more abundant.
It is simple in structure, economical and practical, is the vitals of LNG liquefied natural gas air conditioning for automobiles cold recovery.
