Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is described in detail.
Refer to shown in Fig. 1, this utility model embodiment one new-energy automobile temperature control system coolant injection equipment, bag
Include:
For the filler to temperature control system filling coolant；
For storing the fluid reservoir of coolant, described fluid reservoir is provided with the first snap joint, the second snap joint and
Second cut-offs valve, and wherein, described first snap joint position on described fluid reservoir is less than described second snap joint in institute
State the position on fluid reservoir；
Electric vacuum pump for extracting vacuum；
Described filler is sequentially connected with first by exterior line and cut-offs valve, the first snap joint, and described fluid reservoir passes through
Second snap joint is connected with described electric vacuum pump.
Again as in figure 2 it is shown, the present embodiment devises new filler, including expanding case lid mouth 11 and the pipe being disposed thereon
Mouth 12, expands case lid mouth 11 and is connected with temperature control system movably (the most threaded), and the mouth of pipe 12 is used for connecting exterior tube
Road, and be sequentially connected with first by exterior line and cut-off valve, the first snap joint, filler is coupled together with fluid reservoir, from
And realize the connection of the present embodiment filing provision and new-energy automobile temperature control system.Expand case lid mouth 11 and use machining mode
Being processed into crown cap mouth, the mouth of pipe 12 is then welded on crown cap mouth 11 or one-body molded with crown cap mouth.
Cut-off at filler and first and be also equipped with vacuum meter on the pipeline between valve, for monitoring the vacuum of temperature control system
Situation.
As a kind of example, the first snap joint is arranged on described fluid reservoir bottom, and the second snap joint is arranged on liquid storage
Tank top.
The filing provision of the present embodiment can be used for new energy car battery or liquid cooling system of motor, including emptying and filling two
Individual process.Illustrate respectively below in conjunction with Fig. 3 and Fig. 4.
Refer to shown in Fig. 3, temperature control system (the present embodiment is battery or liquid cooling system of motor) is generally individually provided with discharging valve,
Before carrying out emptying, major part coolant can be discharged by discharging valve, rear section coolant still can remain in temperature control system,
Now the discharging valve of temperature control system being closed, cut-off valve by first and open, second cut-offs valve closes, and opens electric vacuum pump and enter
Row evacuation.In vacuum, in temperature control system remaining coolant can pass sequentially through filler, first cut-off valve, first
Snap joint enters fluid reservoir (coolant flow direction is as shown in dotted arrow in Fig. 3), owing to fluid reservoir volume is relatively big, and first
The position of snap joint is less than the second snap joint, and coolant will not enter electronic by the second snap joint due to action of gravity
Vacuum pump, thus protect electric vacuum pump not to be destroyed.
After vacuum meter index reaches requirement, closing first and cut-off valve, pressurize a period of time simultaneously, pressure keeps constant
Under the conditions of can enter filling process.Refer to shown in Fig. 4, first disconnect the second snap joint during filling, remove electric vacuum pump,
Open second again and cut-off valve, observe fluid reservoir liquid level, when liquid level is unsatisfactory for requiring, inject enough coolants.Then
Opening first again and cut-off valve, the coolant in fluid reservoir passes sequentially through the first snap joint due to atmospheric pressure effect, first opens
Disconnected valve, filler enter temperature control system (coolant flow direction is as shown in dotted arrow in Fig. 4).Owing to aforementioned evacuation procedure makes
Obtain vacuum higher, therefore can realize repeatedly filling, by the first switch conservative control filling speed cut-offfing valve, until cooling
Liquid is full of expansion tank, completes filling process.For the ease of the observation to fluid reservoir liquid level, a kind of mode is to be adopted by fluid reservoir
Make with transparent material, and mark scale at can body, by people's perusal；Another way is installation liquid level in fluid reservoir
Sensor, obtains liquid storage innage information by sensor signal.
The beneficial effects of the utility model are, are applicable to coolant injection in maintenance process, solve tradition filling and set
Problem is filled for electric vacuum pump evacuation cannot be used；By design filler and fluid reservoir, recyclable temperature control system cold
But liquid, protection vacuum pump is not destroyed simultaneously；Use the convenient operation of snap joint, it is achieved fast evacuation and filling.
Above disclosed only this utility model preferred embodiment, can not limit this utility model with this certainly
Interest field, the equivalent variations therefore made according to this utility model claim, still belong to the scope that this utility model is contained.
