Abstract
The utility model relates to a kind of novel practical refrigerant fluid filling structure, it is characterized in that: expansion water tank cover is stamped at expansion tank top, overflow branch road is connected to below the expansion water tank cover at expansion tank top, the cooling line of bifurcated is connected bottom expansion tank, one end of cooling line bifurcated connects water inlet of radiator, the other end of cooling line bifurcated is connected C load successively, B load and A load, radiator outlet connects pump intake by cooling line, the coolant outlet pipe of water pump is connected with the A load water inlet of A load, the coolant outlet pipe of water pump or the A load water inlet of A load can be closed with clip or blocking cap when adding inject cooling liquid.It realizes manual operation can to guarantee in enclosed circulation cooling system loop not detain gas.
Description
Technical field
The utility model relates to a kind of novel practical refrigerant fluid filling structure, belong to car production manufacture and maintenance care field, particularly to the coolant injection that there is enclosed circulation cooling system and the battery-driven car low-temperature cooling system having obvious reducing to exist in water route in parallel, spiral thin footpath water channel or pipeline in load.
Background technology
At present, in electric vehicle engineering application, because space structure limit, generally apply the closed cooling recirculation system of closed cooling and there is saving cooling line arrangement space, refrigerant fluid circulation path is short, cooling performance is high feature.
In actual applications, how because condition limit, coolant injection can only be carried out by manual operation.Before not applying the utility model method of operation, be typically employed in the dosing method that cooling loop vertex opens venting blocking exhaust.But the load due to closed cooling recirculation system: exist in A load, B load, C load in spiral thin footpath water channel or pipeline and have obvious reducing, the resistance be subject to when making refrigerant fluid flow through spiral thin footpath water channel or reducing region is far longer than refrigerant fluid when circulating system vertex expansion tank to other position institute applied pressures of system.Therefore, just cause refrigerant fluid and form backflow filling by the water outlet simultaneously from C load after system vertex expansion tank.Thus the gas in cooling loop is trapped in spiral thin footpath water channel and thin diameter tube road cannot emptying, cause cooling system can not reliable operation, and then cause cooled body Frequent Troubles.
Summary of the invention
The purpose of this utility model is to provide a kind of novel practical refrigerant fluid filling structure, and it realizes manual operation can to guarantee in enclosed circulation cooling system loop not detain gas.
The technical solution of the utility model is achieved in that a kind of novel practical refrigerant fluid filling structure, it is characterized in that: expansion water tank cover is stamped at expansion tank top, overflow branch road is connected to below the expansion water tank cover at expansion tank top, the cooling line of bifurcated is connected bottom expansion tank, one end of cooling line bifurcated connects water inlet of radiator, the other end of cooling line bifurcated is connected C load successively, B load and A load, radiator outlet connects pump intake by cooling line, the coolant outlet pipe of water pump is connected with the A load water inlet of A load, the coolant outlet pipe of water pump or the A load water inlet of A load can be closed with clip or blocking cap when adding inject cooling liquid.
Good effect of the present utility model is that it can be stopped cooling system temperature anomaly and raises, efficient protection cooling system and all multi-loads that will safeguard thereof, realizes manual operation and can to guarantee in enclosed circulation cooling system loop not detain gas.
Accompanying drawing explanation
Fig. 1 constructional drawing of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of novel practical refrigerant fluid filling structure, it is characterized in that: expansion water tank cover 8 is stamped at expansion tank 1 top, overflow branch road 7 is connected to below the expansion water tank cover 8 at expansion tank top, the cooling line of bifurcated is connected bottom expansion tank 1, one end of cooling line bifurcated connects radiator 2 water inlet, the other end of cooling line bifurcated is connected C load 6 successively, B load 5 and A load 4, radiator 2 water outlet connects water pump 3 water inlet by cooling line, the coolant outlet pipe 9 of water pump 3 is connected with the A load water inlet 10 of A load 4, the coolant outlet pipe 9 of water pump 3 or the A load water inlet 10 of A load 4 can be closed with clip 11 or blocking cap when adding inject cooling liquid.
Before cooling down operation of manually annotating, the coolant outlet pipe 9 of water pump 3 and the A load water inlet 10 of A load 4 disconnect, residing level attitude is the highest except expansion tank 1 in this circulating system herein, open expansion water tank cover 8, start to add inject cooling liquid, when refrigerant fluid fully flows out from the coolant outlet pipe 9 of water pump 3 or the A load water inlet 10 of A load 4, the A load water inlet 10 of the coolant outlet pipe 9 of water pump 3 or A load 4 is closed with clip 11 or blocking cap 12, continue to add inject cooling liquid, until when refrigerant fluid fully flows out from the coolant outlet pipe 9 of another interface water pump 3 or the A load water inlet 10 of A load 4, stop filling, recover this place to connect, at some refrigerant fluids of annotating in expansion tank 1 in right amount.So far, end of operation.
If there is parallel pipeline in system, above method also can be used to carry out the filling of segmentation successively to each parallel pipeline.Until again without gas residue in cooling system.
