Description

Technical Field

[0001] This application relates to the technical field of automotive radiators, and particularly to a water chamber for preventing water leakage of a water tank. Background Art

[0002] An automotive radiator is an indispensable component in the cooling system of an automotive water-cooled engine. Through the internal circulation of the coolant in the radiator tubes of the automotive radiator and the forced convection formed by the operation of the external fan, a large amount of heat energy is carried away, enabling the engine to operate normally. The automotive radiator mainly includes a radiator core and upper and lower water chambers installed at the top and bottom of the radiator core. The water enters through the upper water chamber, is cooled by the radiator core, and then the cold water flows out from the lower water chamber to cool the engine.

[0003] Currently, the inlet pipe and outlet pipe of the radiator water chamber are connected to the circulating water pipe by means of socketing and being tightened with a clamp. During long-term use, factors such as vehicle vibration are likely to cause the socket contact to become loose and seep water. Moreover, the wall thickness of the water chamber is relatively thick, and the injection gate is located in the middle of the water chamber. Due to the presence of installation points such as positioning posts at both ends of the water chamber, the wall thickness at both ends of the water chamber is too thick, resulting in air holes during injection molding and causing water leakage of the water tank.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

The sealing rings on the edge bindings 3 improve the sealing performance after the water chamber is fixed to the radiator core and avoid water leakage. When injecting the water chamber, the position of the glue inlet point is adjusted to the positioning columns to reduce the wall thickness and eliminate air holes, thereby solving leakage problems.

[0023] Furthermore, the water chamber is made of glass fiber nylon, which is nylon added with glass fiber, such as PA66 (polyamide 66 or nylon 66) + 30% GF (Glass Fiber), also known as PA66GF30, and the wall thickness of the water chamber is 3 mm.

[0024] Further, a drain pipe 10 is fixedly sleeved at the bottom of the outer wall of one end of the water inlet chamber housing 2 away from the water outlet pipe 5. A valve is installed on the drain pipe 10, and an exhaust valve is installed on the top of the water inlet chamber housing 1. The drain pipe 10 is located at the lowest end of the water inlet chamber housing 2, which is convenient for emptying when replacing the coolant. The exhaust valve adopts a one-way valve, which is convenient for exhausting.

[0025] Refer to Figure 2 , the sealing cover 9 is threadedly sleeved on the filling port 8. A blocking block 11 is fixedly installed at the top of the inner cavity of the sealing cover 9. The blocking block 11 is movably clamped in the filling port 8, and a plurality of O-rings 12 are fixedly embedded on the outer wall of the blocking block 11. The O-rings 12 are closely attached to the inner wall of the filling port 8. When the sealing cover 9 is threadedly connected to the filling port 8, the blocking block 11 is inserted into the filling port 8, and the O-rings 12 are attached to the inner wall of the filling port 8, improving the sealing performance.

[0026] Refer to Figure 1 and Figure 3 , flange rings 13 are fixedly sleeved on the outer walls of the water inlet pipe 4, the water outlet pipe 5 and the connecting pipe 6. Slots 14 are opened on the inner walls of the end faces of the water inlet pipe 4 and the water outlet pipe 5. An inserting pipe 15 is fixedly installed at the end of the connecting pipe 6. The inserting pipe 15 is movably sleeved in the slot 14. The flange rings 13 on the connecting pipe 6, the water inlet pipe 4 and the water outlet pipe 5 are connected by bolts and nuts. The connecting pipe 6 is clamped in the slot 14 through the inserting pipe 15 and connected by the flange rings 13 and bolts, improving the connection stability.

[0027] Refer to Figure 3 and Figure 4, a rubber ring 21 is embedded and installed on the inner end face of the slot 14, the end of the insertion tube 15 is tightly pressed against the rubber ring 21, a movable ring 16 is movably sleeved on the water inlet pipe 4 and the water outlet pipe 5, through holes are formed in the movable ring 16 and are aligned with the bolt holes of the flange ring 13, one ends of a spring 17 and a drum air bag 18 are embedded and installed on the end faces of the flange rings 13 of the water inlet pipe 4 and the water outlet pipe 5, the other ends of the spring 17 and the drum air bag 18 are fixedly connected to the movable ring 16, a storage groove 19 is formed in the circumferential inner wall of the slot 14, the inner wall of the storage groove 19 is fixedly connected to the circumferential outer wall of a sealing bag 20, the sealing bag 20 is folded in the storage groove 19, an air pipe is fixedly sleeved in the water inlet pipe 4 and the water outlet pipe 5, the sealing bag 20 is connected to the drum air bag 18 through the air pipe, after the insertion tube 15 is inserted into the slot 14, the rear end face is attached to the rubber ring 21, bolts pass through the through holes of the movable ring 16 and the flange ring 13 and are tightened by nuts, the insertion tube 15 presses the rubber ring 21 to improve the sealing performance. Moreover, when the insertion tube 15 is inserted, the elastic force of the spring 17 causes the movable ring 16 to move away from the flange ring 13. At this time, the drum air bag 18 sucks the sealing bag 20, so that the sealing bag 20 is received in the storage groove 19, facilitating the insertion of the insertion tube 15. When the bolts are tightened, the movable ring 16 presses against the flange ring 13, causing the drum air bag 18 to be compressed, and then the gas is squeezed into the sealing bag 20, causing the sealing bag 20 to expand and fit against the outer wall of the insertion tube 15, further improving the sealing performance and preventing water leakage.

[0028] The implementation principle of a water chamber for preventing water leakage in an embodiment of the present application is as follows: the upper water chamber shell 1 and the lower water chamber shell 2 are respectively installed at the top and bottom of the radiator core, and a circle of inner edge of the outer edge of the radiator main fins is wrapped by the edge 3 and fixed by brazing. The sealing ring on the edge 3 improves the sealing performance after the water chamber is fixed to the radiator core, preventing water leakage. When the water chamber is injection-molded, the position of the glue inlet point is adjusted to the positioning post, reducing the wall thickness, eliminating air holes, and preventing leakage. When the sealing cover 9 is threadedly connected to the filling port 8, the plug 11 is stuck into the filling port 8, and the O-ring 12 fits against the inner wall of the filling port 8 to improve the sealing performance. The insertion tube 15 is movably sleeved in the slot 14, and the connecting pipe 6 is connected to the flange rings 13 on the water inlet pipe 4 and the water outlet pipe 5 through bolts and nuts. The connecting pipe 6 is clamped to the slot 14 through the insertion tube 15 and connected through the flange ring 13 and bolts to improve the connection stability. After the insertion tube 15 is inserted into the slot 14, the rear end face is attached to the rubber ring 21, bolts pass through the through holes of the movable ring 16 and the flange ring 13 and are tightened by nuts, the insertion tube 15 presses the rubber ring 21 to improve the sealing performance. Moreover, when the insertion tube 15 is inserted, the elastic force of the spring 17 causes the movable ring 16 to move away from the flange ring 13. At this time, the drum air bag 18 sucks the sealing bag 20, so that the sealing bag 20 is received in the storage groove 19, facilitating the insertion of the insertion tube 15. When the bolts are tightened, the movable ring 16 presses against the flange ring 13, causing the drum air bag 18 to be compressed, and then the gas is squeezed into the sealing bag 20, causing the sealing bag 20 to expand and fit against the outer wall of the insertion tube 15, further improving the sealing performance and preventing water leakage.
