Description

Technical Field

[0001] The utility model relates to the technical field of coolant adding devices, in particular to an automobile coolant adding device. Background Art

[0002] Car coolant, also known as antifreeze, is a medium that protects car engines. It has two main functions: to cool the engine when it is running to prevent damage to the engine due to excessive temperature, and to prevent the car's cooling system from freezing when the temperature is too low in winter, which has an antifreeze effect. The freezing point and boiling point of coolant are different from those of water, which is why it can have two opposite effects of cooling and antifreeze at the same time. Car coolant still has a certain service life. Under high temperature conditions, some components of the coolant will react to produce ethanol, which will then combine with other components in the coolant to form harmless substances. However, when the reaction is complete, the ethanol generated again cannot be eliminated, and a high content will cause damage to metal parts. Therefore, the coolant should be replaced periodically to ensure that the cooling system can operate normally.

[0003] When replacing the car coolant, the air in the system needs to be emptied to ensure that there are no bubbles inside the cooling system to ensure the normal operation of the system. The traditional method of evacuating the air is: open the radiator cap (it can only be opened when the engine is completely cooled), start the engine, adjust the heating and fan to the highest level, let the engine reach the operating temperature naturally, keep the engine running, and then slowly add coolant to the top of the radiator until no more bubbles emerge, pay attention to the coolant level to avoid overflow, close the radiator cap, and continue to run the engine for a few minutes to ensure that the air in the cooling system is evacuated. After the engine cools down, check the coolant level again and add coolant to the appropriate position if necessary. However, the traditional method of evacuating the air is more cumbersome, time-consuming, and inconvenient to use.

[0004] In view of the above problems, the utility model document proposes a vehicle coolant adding device. Utility Model Content
