It is then the task of automobile cooling system.It mainly include air-cooled and liquid cooling in automobile radiator systems, liquid cooling cooling system is by starting
Pipeline and access in machine carry out the circulation of liquid, and heat can be absorbed when liquid flows through high-temperature engine, start to reduce
The temperature of machine after liquid flows through engine, then flows to heat exchanger (or radiator), and the heat in liquid passes through heat exchanger
It is dispersed into air.
An a kind of entitled patent for new-energy automobile radiator, this kind of new-energy automobile are disclosed in Data of China library
With radiator, including upper frame and lower frame, heat-dissipating pipe is equipped between upper frame and lower frame, heat-dissipating pipe uses serpentine configuration,
Metallic heat radiating plate is also fixedly connected between upper frame and lower frame, upper frame is equipped with first through hole, and lower frame is equipped with second
Through-hole, first through hole are connected to the cooling liquid inlet of heat-dissipating pipe, and the second through-hole is connected to the cooling liquid outlet of heat-dissipating pipe.This kind dissipates
The structure of hot device is simple, can be realized the cooling to automobile current generator, but there is pipeline with air contact surfaces in this kind of radiator
It limits, coolant liquid and tube body contact area are limited in pipeline, can not improve the heat-sinking capability of tube body itself effectively.
Utility model content
The purpose of the utility model is to provide a kind of increase tube body heat dissipation area itself, increase coolant liquid and tube body contact surface
Long-pending heat-dissipating pipe.
In order to realize above-mentioned purpose of utility model, a kind of heat-dissipating pipe of the utility model is adopted the following technical scheme that
A kind of heat-dissipating pipe, including tube body, tube body both ends are respectively liquid feeding end and outlet end, axially disposed in the tube body
Have the first partition that tube cavity is divided into first chamber and second chamber, the second chamber be located at liquid feeding end be provided with by
The second partition that second chamber is isolated from the outside, the outer surface of tube body is circumferentially arranged a protrusion of annular, outside the tube body
Surface is arranged in the axial direction with multiple protrusions, and the protrusion is provided with the inner cavity of annular with tube body contact position, and the first chamber is opened
Inlet equipped with connection inner cavity, second chamber open up the liquid outlet of connection inner cavity.Coolant liquid passes through in automobile cooling system
Water pump is conveyed into liquid feeding end, and coolant liquid travels forward in first chamber, the part coolant liquid point when by each inlet
Stream enters inlet, and as inlet flows into the inner cavity of protrusion, then flows into second chamber by the liquid outlet of the other side, passes through
Second chamber flow forward, the coolant liquid in first chamber and second chamber flow out this kind of heat-dissipating pipe in outlet end.
The inlet is set to the lower half portion of tube body, and the liquid outlet is set to the top half of tube body.Outlet end
It is set to bottom of the pipe, coolant liquid is more easier to flow into the inner cavity of protrusion, and liquid outlet is set to tube body upper end, this kind setting
The coolant liquid of inner cavity is forced by most inner cavities, increases the heat dissipation area of coolant liquid.
The convex cross section is parabolic shape, and raised height is greater than the width of protrusion.The protrusion of this kind of shape makes convex
Playing itself has biggish heat dissipation area.
The inlet is the liquid flow direction setting along coolant liquid in tube body.This kind setting makes cold in first chamber
But liquid more easily enters inlet in flowing.
The liquid outlet is the liquid flow direction setting along coolant liquid in tube body.This kind setting makes cold in raised inner cavity
But when liquid stream enters second chamber can in second chamber coolant liquid flow direction, reduce when coolant liquid flows into second chamber to the
The disturbance of coolant liquid in two chambers reduces impact of the coolant liquid to tube body, reduces therefore vibration that tube body generates.
The inlet is equipped with draining hole close to the side of liquid feeding end, and the draining hole is in horn-like.Draining hole reduces cold
But resistance when liquid stream enters inlet makes coolant liquid be easier to flow into inlet.
The liquid outlet is equipped with flow-guiding mouth close to the side of outlet end, and the flow-guiding mouth is in horn-like.Flow-guiding mouth reduces cold
But resistance when liquid stream goes out liquid outlet, excessively more gentle when flowing out coolant liquid, coolant liquid is more steady when flowing out.
The protrusion and outer surface of tube body are covered with thermal grease.Thermal grease is used to increase the thermal diffusivity of tube body and protrusion
Energy.
Compared with prior art, the utility model has the beneficial effects that: the coolant liquid in first chamber passes through inlet,
Enter second chamber behind the inner cavity of protrusion, on the one hand protrusion increases the heat dissipation area of tube body itself, on the other hand increases
The contact area of coolant liquid and tube body, improves the radiating efficiency of tube body.
