Description
Technical field
The present invention relates to a kind of automobile-used overflow tank more particularly to a kind of noise reduction overflow tanks, belong to auto parts and components.
Background technology
Automobile-used overflow tank is also known as expansion tank, is the important spare part of automobile, and quality is directly related to vehicle performance and relaxes
Adaptive.Since the noise that traditional power vehicle engine generates is far longer than the noise generated inside overflow tank, overflow tank
Noise reduction has little significance, and does not consider overflow tank noise reduction problem usually.
With the rise of new-energy automobile, overflow tank is not only only used to cool down engine, but also for cooling down battery
The parts such as packet participate in entire cooling recirculation system work.Since cooling-part is more, in the case where tank-volumes are constant, lead to
Often improve the feed flow of coolant liquid；The production of the factors such as the circulatory system is inhaled into the impact of babinet, air including coolant liquid
Raw noise can seriously affect riding comfort.Therefore how to reduce overflow tank interior noise, responsive motor development demand
A technical problem through can not ignore as the mating producer of many auto parts and components.
Invention content
In view of the above defects of the prior art, the present invention is intended to provide a kind of noise reduction overflow tank, current to solve
New-energy automobile overflow tank big problem of noise under 12L/min flows.
To achieve the goals above, the present invention uses following technical scheme：It includes being welded by upper box and lower box pairing
Babinet made of connecing has pneumostome, inlet tube and outlet tube on the babinet；Wherein：
The upper diversion column of C fonts is fixed in upper box, be fixed in upper box and one end connect with upper tank wall the other end with
The first upper spacer, the second upper spacer and the third upper spacer of upper water conservancy diversion column outer wall connection by upper box be divided into upper admission chamber, on
Cushion chamber and above go out sap cavity；Between upper admission chamber and upper cushion chamber by the half bore on the first of the first upper spacer bottom end and
Positioned at the first upper spacer top the first stomata be connected to, upper cushion chamber and on go out between sap cavity by being located at the second upper spacer bottom end
Second on half bore and positioned at the second upper spacer top the second stomata be connected to；Pneumostome is fixed on the top of upper box, and
It is connected to by the opening of upper diversion column with sap cavity is gone out；The inlet tube for being fixed on top box body side surface is connected to upper admission chamber；
The lower diversion column of C fonts is fixed in lower box, be fixed in lower box and one end connect with lower tank wall the other end with
The first lower clapboard, the second lower clapboard and the third lower clapboard of lower water conservancy diversion column outer wall connection by lower box be divided into lower admission chamber, under
Cushion chamber goes out sap cavity under；Between lower admission chamber and lower cushion chamber by first time half bore positioned at the first lower clapboard top and
Positioned at the first lower clapboard bottom end the first low level mouth be connected to, lower cushion chamber and under go out between sap cavity by being located at the second lower clapboard top
The second time half bore held and the second low level mouth positioned at the second lower clapboard bottom end are connected to；Outlet tube is fixed on the bottom of lower box
Portion, and sap cavity is gone out under by the opening of lower diversion column and is connected to；
Upper diversion column, the first upper spacer, the second upper spacer and third upper spacer position respectively under lower diversion column, first every
Plate, the second lower clapboard and third lower clapboard position correspond to；Upper box and upper admission chamber after lower box pairing and lower admission chamber shape
At intake chamber, upper cushion chamber and lower cushion chamber formed surge chamber, on go out sap cavity and go out sap cavity under to form liquid outtake chamber.
Be fixed with water conservancy diversion triangle hole post on the inner wall of upper admission chamber, inlet tube by the lower end of the water conservancy diversion triangular prism with it is enterprising
Sap cavity is connected to.
Compared with the prior art, therefore the present invention is by adopting the above-described technical solution, have the advantages that have：
1）Due to increasing high liquid level recirculation hole and low liquid level recirculation hole, passing through naturally for 12L/min flows can be met, and
Bubble can be hindered to enter cooling recirculation system from the bottom of box；Can also fluid infusion efficiently be carried out to liquid outtake chamber simultaneously, effectively prevent
Liquid outtake chamber's liquid level is too low, and air is inhaled into and generates noise；
2）As a result of low liquid level recirculation hole, even if when cooling liquid measure deficiency, it also can be by positioned at bottom of box lowest point
Low liquid level recirculation hole circulates, and participates in cooling cycle；Meanwhile when adding coolant liquid, can also coolant liquid be made to could quickly fill up case
Each chamber of body submits addition efficiency；
3）Due to increasing surge chamber, coolant liquid enters back into liquid outtake chamber from the buffered room of intake chamber, coolant liquid is avoided to be directly entered
Liquid outtake chamber can make bubble have time enough to float up on liquid level during reaching liquid outtake chamber by surge chamber, reduce
Bubble is inhaled into the probability of coolant circulation system, and noise source is blocked from coolant flow paths；
4）Due to increasing water conservancy diversion triangle hole post, coolant liquid flows back from inlet tube, by water conservancy diversion triangle hole post disperses impact forces degree,
Weaken impact noise；In addition, water conservancy diversion triangle hole post can also guide coolant liquid the MIN lines to setting hereinafter, coolant liquid is avoided to rush
It hits liquid level and generates bubble, containment bubble is generated, control effectively from noise source.
