Technical field
The present invention relates to the air conditioning for automobiles field, be specifically related to a kind of vortex countercurrent evaporation device of parallel flow type.
Background technology
Automobile air-conditioning evaporator is one of core component of automotive air-conditioning system, and the design of evaporimeter directly affects the performance of air-conditioning system, and affects the compact of car load.At present the evaporimeter kind of used for automobile air conditioning is a lot, mainly contains pipe type, corrugated tube type, stacked, parallel flow type etc.Early stage automobile air-conditioning evaporator generally is pipe sheet type structure, develops into the corrugated tube type structure again, so far the evaporimeter of the parallel flow type of main flow even stacked parallel flow type.
Along with the development of auto industry and air conditioning for automobiles industry, automobile air-conditioning evaporator is just towards the future development of high heat exchange efficiency, environmental protection, miniature energy-saving and automation, and is also more and more higher to the requirement of evaporimeter.The parallel flow evaporators of main flow adopts rectangular configuration at present, comprise a plurality of straight flat tube that is arranged in juxtaposition, between each straight flat tube with accordion fin interval, the refrigerant inlet end of straight flat tube is connected header with the port of export, the deficiency that exists is: the rectangular configuration area occupied is large, particularly the stacked stacked concurrent flow of a plurality of straight flat tubes has increased thickness especially, and this layout for kart is totally unfavorable; Moreover the straight flat tube that parallel-flow evaporator adopts easily expands or vibration deformation under some mal-condition, affects the circulation of cold-producing medium; Again, for straight flat tube, the cold-producing medium stroke is short, and refrigerating efficiency is not high enough, and the vehicle refrigeration demand under some working environment is large, and refrigerating efficiency is had higher requirement; In addition, accordion fin complex manufacturing, the soldering difficulty is high, the man-made assemblies that adopt between flat tube, header, the fin more, the assembling difficulty is high.
Summary of the invention
In order to solve the aforementioned problems in the prior, to the invention provides that a kind of compact conformation, area occupied are little, be difficult under the mal-condition because of the vortex parallel flow/counter flow evaporator for vehicle air conditioner that the distortion of the reasons such as stressed, vibration, heat expansion affect cross section of fluid channel, the cold-producing medium circulation is smooth and easy, the cold-producing medium stroke enlarges markedly, refrigerating efficiency raising, difficulty of processing significantly reduce.
The present invention adopts following technical scheme:
Vortex parallel flow/counter flow evaporator for vehicle air conditioner, the Scrawl flat tube that swirl shape extends that is that comprises a plurality of parallel layouts, between each Scrawl flat tube with the fin interval, Scrawl flat tube inner chamber forms refrigerant flow path, be tightly connected between the adjacent vortex sheet of single Scrawl flat tube and the both sides fin, consist of the refrigerating medium runner with the cold-producing medium heat exchange, the import of each refrigerant flow path and outlet are interconnected respectively, the import of each refrigerating medium runner and outlet are interconnected respectively, the cold-producing medium in the refrigerant flow path and the refrigerating medium reverse flow in the refrigerating medium runner.
Further, the outermost end of described Scrawl flat tube is furnished with the first header that is communicated with the outlet of each refrigerant flow path, and the center arrangement of described Scrawl flat tube has the second header that is communicated with the import of each refrigerant flow path.
Further, described evaporimeter also comprises cylinder type shell, and the cylinder type shell inboard is provided with the slot that is connected with fin.
Preferably, described fin is flat thin ring fin, and the center of flat thin ring fin is equipped with described the second header.
Further, be provided with the air inlet duct that is communicated with the import of each refrigerating medium runner on the described cylinder type shell.Technical conceive of the present invention is: design vehicle idle call vortex parallel flow/counter flow evaporator, this evaporimeter adopts and is the Scrawl flat tube that swirl shape extends, with respect to adopting stacked straight flat tube, adopt the Scrawl flat tube so that structure is compacter, overall dimensions greatly reduces, and the cylindrical shape evaporimeter of equal length is arranged in small-sized front part of the carriage near the driver's cabin side than the rectangle evaporimeter is easier; Consider from the heat exchange angle, because the Scrawl flat tube increases greatly with respect to the straight flat tube equivalent length of same height, so Scrawl flat tube inner chamber forms the refrigerant flow path length increase of Scrawl, the phenomenal growth of cold-producing medium stroke, the heat exchange path increases, and heat exchange efficiency improves; And the reverse convection of the cold-producing medium in the refrigerant flow path and the refrigerating medium in the refrigerating medium runner has further improved again heat exchange efficiency; Secondly, the Scrawl flat tube can be formed by the straight flat tube bending of present main flow parallel-flow evaporator, make simple, the more straight flat tube strength increase of while turbulent structure, therefore the yet more difficult former thereby distortion because of stressed, vibration, heat expansion etc. can not affect cross section of fluid channel and then affect the smoothness that cold-producing medium circulates under the abominable condition of work; In addition, flat thin ring fin has replaced the accordion fin, has simplified production technology, and the soldering difficulty reduces, and easily is automated assembling between flat tube, header, the fin.
Beneficial effect of the present invention is: (1) compact conformation, area occupied are little; (2) be difficult under the mal-condition because the distortion of the reasons such as stressed, vibration, heat expansion affects cross section of fluid channel, the cold-producing medium circulation is smooth and easy; (3) the cold-producing medium stroke enlarges markedly, refrigerating efficiency improves; (4) production technology simplification, difficulty of processing significantly reduce.
