Description
Technical field
The utility model is related to a kind of automobile components, specifically a kind of car expansion tank.
Background technology
Since reform and opening-up, particularly Domestic Automotive Industry growth momentum is powerful in recent years, and China became after beautiful, day
3rd automobile produces country ten million broken per year, into ten million automobile superpower ranks.It is this swift and violent in order to meet automobile industry
The requirement of development, for the auto parts and components that the speed of production and quality of automobile play a decisive role form a complete production network producer,
The structure of the component produced, quality and quantitative requirement are higher and higher.
In the prior art, the filler on car expansion tank is directly communicated with water-supplying chamber in expansion tank, and such water hangs down
Direct current enters in reservoir chamber, easily brings gas in water into, easily causes and stirs or splash, and is unfavorable for pressure balance and system in system
The discharge of interior gas, therefore need a kind of expansible water tank that can guarantee coolant and can steadily operate.
The content of the invention
The purpose of this utility model is to provide for a kind of rational in infrastructure, simple installation, both artistic and practical, it is not easy to by gas band
Enter in water, will not cause and stir or splash, be conducive to the discharge of gas in pressure balance and system in system, can guarantee coolant
The new automobile expansion tank that can steadily operate.
The purpose of this utility model is achieved in that a kind of car expansion tank, which includes the swelling water
Case include expansion water tank cover, be threadedly coupled with expansion water tank cover expansion tank upper body, be arranged under expansion tank upper body
The expansion tank lower body in face and the overflow pipe for being arranged on expansion tank upper body side, expansion tank upper body centre band
There are one filling opening, top edges to be set there are one inlet tube, and there are one the overflow ports of connection overflow pipe for side band；Expansion tank
Lower body is internally provided with one with inlet tube position to positive surge chamber, and the edge being open in expansion tank lower body carries one
A circular edge welding bar and two fixing points of one week, in the bottom of expansion tank lower body, there are one return duct and one for setting
A positioning column.
The utility model is rational in infrastructure, simple installation, both artistic and practical, it is not easy to bring in water gas into, will not cause and turn over
It is dynamic or splash, be conducive to the discharge of gas in pressure balance and system in system, be that one kind can guarantee that coolant can be transported steadily
The new automobile expansion tank turned.
Description of the drawings
Fig. 1 is the utility model dimensional decomposition structure figure.
Specific embodiment
As shown in attached drawing 1：The expansion tank that the expansion tank includes expansion water tank cover 1, is threadedly coupled with expansion water tank cover 1
Upper body 2, the expansion tank lower body 3 being arranged below expansion tank upper body 2 and it is arranged on 2 side of expansion tank upper body
Overflow pipe 4, there are one filling opening 12, top edges to set there are one feed liquor for the 2 centre band of expansion tank upper body
Pipe 5, there are one the overflow ports 11 of connection overflow pipe 4 for side band；The expansion tank lower body 3 is internally provided with one and feed liquor
5 position of pipe is to positive surge chamber 6, and there are one around the edge welding bar of one week for the marginal belt being open in expansion tank lower body 3
10 and two fixing points 9, set that there are one return duct 7 and a positioning columns 8 in the bottom of expansion tank lower body 3.
The expansion water tank cover 1 unscrews lid, you can pour into cooling for coolant to be sealed in water tank when increasing liquid
Liquid；The expansion tank upper body 2 is injection molding, for welding to form closed tank with lower body；Under the expansion tank
Body 3 is injection molding, for welding to form closed tank with upper body；The overflow pipe 4 is used for when liquid expansion in water tank
Afterwards, extra liquid flows out from there；The inlet tube 5 makes coolant enter water tank from the position in normal work；It is described
Surge chamber 6, to just, the surge chamber being introduced into when liquid flow is fashionable, is then flowed by top side wall in water tank with inlet tube position,
The bubble that liquid splash generates can be prevented to be directly entered return duct；The return duct 7 is used to liquid flowing out water tank from the pipe；Institute
Positioning column 8 is stated for positioning relative position of the expansion tank in car body；The fixed point 9 is at totally two, for using screw by water
Case is fixed on vehicle body；The welding bar 10 surround edge one week, is the welding structure of upper and lower tank body, is formed after welding close
The entirety of envelope；The overflow port 11 is for connecting overflow pipe, and extra air or liquid can thus outflow waters after coolant expansion
Case；The filling opening 12 for water tank level it is too low when, thus place increase liquid.
