Abstract
The utility model provides a coaxitron for a vehicle air-conditioning system. The coaxitron comprises a pipe body composed of an inner pipe and an outer pipe, wherein the inner pipe is located in the outer pipe; the space between the inner pipe and the outer pipe is a medium flowing outer cavity; the inner space of the inner pipe is a medium flowing inner cavity; a plurality of heat conduction tanks are distributed on the inner surface of the inner pipe; and a plurality of beads are distributed on the inner surface of the outer pipe. The coaxitron is high in heat exchange efficiency; by using the coaxitron, the engine working power occupied by a refrigerating system can be reduced; fuel and energy resources are saved; exhaust emission is reduced; the space occupied by the system refrigerating pipeline in an engine room can be reduced, and the space reserved for other main components by vehicle manufacturers during vehicle design procedures is increased.
Description
Technical field
The utility model relates to a kind of coaxitron for automotive air-conditioning system.
Background technology
The air conditioning for automobiles industry is faced with new technological innovation now.Well-known air conditioning for automobiles is that to adopt the power of engine be that cost is finished and regulated the air in a car compartment environment.And the working environment of automobile directly is subjected to the impact of sunlight, frost and snow, wind and rain etc. because of in the open air, and environmental change is violent.Make air conditioning for automobiles efficiently operation in like this environment, just require its refrigerating capacity large especially, thereby greatly improved the engine operation load, the coefficient such as oil consumption is improved greatly.General refrigeration pipe can't accomplish to take full advantage of the refrigerating capacity that vehicle produces in the process of moving, thus need to improve air conditioning for automobiles heat-exchange tube line structure, thus reduce the oil consumption of automobile in running, energy savings.
Summary of the invention
Technical scheme to be solved in the utility model provides the high coaxitron that is used for automotive air-conditioning system of a kind of heat exchange efficiency, for this reason, the utility model is by the following technical solutions: it comprises the body that is comprised of inner and outer tubes, inner tube is positioned at outer tube inside, wherein the space between inner tube and the outer tube is the media flow exocoel, and the inner space of inner tube is the media flow inner chamber; Distribution multiple tracks thermal trough on the interior pipe internal surface, distribution multiple tracks fin on the outer pipe internal surface.
On the basis of adopting technique scheme, the utility model also can adopt following further technical scheme:
Outer surface in inner tube is the circular arc smooth surface.
Described fin is axial linearity.
Described thermal trough is axial linearity.
At the two ends of described coaxitron difference welded sleeve, described sleeve has the first axial interface that is connected with inner tube, the second axial interface that is connected with outer tube and takes over the radially interface that is connected with liquid, described media flow exocoel is taken over by sleeve and liquid and is connected, described inner tube two ends are connected with gas-tpe fitting, and described liquid is taken over an end, and the interface connection other end is connected with liquid pipe connection with being connected radially.
The utility model is in the refrigeration system course of work, high temperature refrigerant flows in the media flow inner chamber, low-temperature refrigerant flows in the media flow exocoel, during the different cold-producing medium of high low temperature flows in coaxitron, high temperature refrigerant carries out heat exchange by the low-temperature refrigerant that flows in the heat conduction cell wall in the inner tube and the media flow exocoel, outer pipe internal surface fin guarantees the space of media flow exocoel and low-temperature refrigerant can smooth and easyly be flowed, thereby raising heat exchange efficiency, thereby the refrigerant temperature in the reduction high-voltage tube, the refrigerant temperature that enters throttle mechanism is reduced, reduce throttle mechanism to the flow resistance of system refrigerant, make the refrigerant temperature that enters heat exchanger more stable, refrigerating efficiency in the raising system running reduces the sense of discomfort that the variation of the refrigerating capacity that the variation of operating mode that vehicle causes because of the change of environment and the speed of a motor vehicle in the process of moving and air-cooled amount causes brings to driver and crew.Use the utility model and can reduce refrigeration system to the tying up of engine operation power, save fuel oil, reduce toxic emission, energy savings.Use the utility model and can reduce cooling system pipeline shared space in enging cabin, increase auto vendor in the vehicle design process to other critical piece headspaces.
