Abstract
The utility model discloses a liquid-cooling circulation device, which comprises a circulating pump and a circulation pipeline; wherein, the circulation pipeline comprises a main liquid inlet pipe and a main liquid outlet pipe which are connected with the circulating pump; a plurality of branch pipelines connected with heat exchangers and radiators are connected in parallel between the main liquid inlet pipe and the main liquid outlet pipe; the main liquid inlet pipe or/and the main liquid outlet pipe are obliquely arranged; the upper parts of the main liquid inlet pipe or/and the main liquid outlet pipe are higher than the circulating pump and other units arranged in the circulation pipeline; and exhaust units are arranged on the pipe walls of the higher parts of the main liquid inlet pipe or/and the main liquid outlet pipe. The liquid-cooling circulation device has the following advantages: exhaust is convenient and complete; the drainage of cooling liquid is reduced; and the operation of the circulating pump is not affected.
Description
Technical field
The utility model relates to a kind of refrigeration plant, relates in particular to a kind of liquid cooling EGR.
Background technology
Refrigeration plant often adopts circulating pump to carry out the circulation of liquid cooling system at present, if there is bubble, circulating pump is cavitated in the system, has a strong impact on the life-span of pump,, need discharge intrasystem gas in system's fluid injection for this reason.Existing exhaust mode is: be connected with Pressure gauge and quick crossover sub on circulating pump pump housing top by tube connector, the operation circulating pump, in the gauge hand swing explanation pump superjacent air space bubble is arranged, stop circulating pump, open quick crossover sub exhaust, after bubble is discharged, circulating pump reruns, repeat above operation, do not swing or swing when not obvious when gauge hand, the bubble in the proof system has been arranged substantially.Because circulating pump generally is placed on position relatively low in the whole circulation system, when circulating pump stops, a large amount of bubbles can turn back to peak or the local peak in the liquid cooling system circulation line, peak in the circulation line or local peak can't exhausts, cause the bubble of circulation line to be not easy discharging fully, and required evacuation time is very long; In addition, because exhaust in the lower position of circulation line, can be discharged more cooling fluid in the exhaust process.
The utility model content
The technical problems to be solved in the utility model provide a kind of exhaust and convenient fully, reduce cooling fluid discharge, do not influence the liquid cooling circulating exhaust device of circulating pump work.
The utility model solves above-mentioned technical problem by the following technical programs: a kind of liquid cooling EGR, comprise circulating pump, circulation line, wherein circulation line comprises total feed tube, the main drain pipe that is connected with circulating pump, be parallel with the many branch lines that are connected with heat exchanger or radiator between the two, total feed tube or/and main drain pipe be obliquely installed, its upper end is higher than other devices that are provided with in circulating pump and the circulation line, and total feed tube is or/and the raised area tube wall of main drain pipe is provided with exhaust apparatus.
Described total feed tube is provided with exhaust apparatus or/and main drain pipe vertically is provided with on the two is not less than the tube wall of best result bye-pass.
Described total feed tube and main drain pipe all vertically are provided with, and described exhaust apparatus is separately positioned on the upper end of the two.
Be higher than total feed tube of best result bye-pass, the upper end of main drain pipe is provided with air collecting chamber.
Described exhaust apparatus is an automatic exhaust steam valve.
Described exhaust apparatus is a manual exhaust valve.
The utility model adopts at the total feed tube that tilts and or/and be higher than the position of other devices of circulation line on the main drain pipe exhaust apparatus is set, operation circulating pump a period of time termination of pumping, because the main liquid inlet and outlet tube sectional area is bigger, cooling fluid speed is low, gas-liquid is separated easily, gas in the circulation line rises and is collected to total feed tube or/and bubble is discharged by exhaust apparatus then in the top of main drain pipe, repeats above operation and the gas of circulation line can be discharged fully; When system begins to add inject cooling liquid, just can exit, thereby can reduce time of exhaust by exhaust apparatus; And exhaust apparatus is arranged on the high point of circulation line, and bubble is assembled easily, and the exhaust efficiency height also can reduce the discharge of cooling fluid; The mode that preferred total feed tube of the utility model and main drain pipe all vertically are provided with, and has one section difference in height between the highest branch line and the exhaust apparatus, be formed with air collecting chamber in total feed tube, main drain pipe upper end, even a spot of bubble is arranged in the system, can build up at the air collecting chamber on main liquid inlet and outlet tube top, prevent that bubble from entering branch line, can not enter circulation, thereby can reduce infringement to circulating pump, exhaust apparatus is an air bleeding valve, can take automatic vent or manually exhaust, convenient and practical.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of liquid cooling EGR, comprise circulating pump 7, circulation line, wherein circulation line comprises the total feed tube 1 that is connected with circulating pump 7, main drain pipe 2, be parallel with the many branch lines 3 that are connected with heat exchanger 8 between the two, what branch line 3 connected can also be radiator 8, total feed tube 1 and main drain pipe 2 one of them or the two all are obliquely installed, the top of tipping tube is higher than other devices that are provided with in circulating pump 7 and the circulation line, wherein preferred total feed tube 1 all vertically is provided with main drain pipe 2, at the total feed tube 1 that is higher than best result bye-pass 3a, the upper end of main drain pipe 2 is provided with air collecting chamber 6, being not less than on the tube wall of best result bye-pass 3a at the two is that air collecting chamber 6 places are provided with exhaust apparatus 5, preferred exhaust apparatus 5 is separately positioned on the upper end of the two, and described exhaust apparatus is an automatic exhaust steam valve 5.
