Description
Technical Field
[0001] The utility model relates to the technical field of automobile cooling, in particular to an automobile coolant kettle. Background Art
[0002] As we all know, the car coolant kettle is an important component in the cooling system. It is usually located in the engine compartment. Its main function is to store and supply coolant to help maintain the engine running within a suitable operating temperature range. The coolant kettle is usually made of heat-resistant plastic or metal material and has a transparent or translucent shell to facilitate checking the coolant level. The coolant kettle is usually connected to other components in the cooling system to control the engine temperature through circulation and heat dissipation.
[0003] However, in traditional automobile coolant kettles, when the cooling system is working, part of the pipes will be in a high temperature state, so it is easy for steam to flow back into the coolant kettle. At this time, the system pressure will also change accordingly. If the steam cannot be discharged in time, it may cause gas groups to form in the system, causing high water temperature. The unstable system pressure will also cause the cooling system to work poorly. Therefore, technical improvements are urgently needed. Utility Model Content

When the automobile coolant kettle is in use, when high temperature is generated inside and the pressure changes accordingly, the set threshold is reached through the pressure sensor, and an electrical signal is sent to the electric control valve. By opening the electric control valve, the steam generated in the pipeline is conveniently transported to the outside through the vent pipe, and part of the steam is conveniently transported to the outside through the air outlet through the flow hole, so that the steam can be discharged more evenly, avoiding the problems of pressure imbalance and poor flow caused by concentrated exhaust at one position, and being able to discharge the steam in the coolant kettle, thereby preventing the system pressure from being too high and causing the cooling system to work poorly, thereby balancing the system pressure.
