What is the car thermostat tee
The automobile thermostat tee is an important part of the automobile cooling system, which is mainly used to control the flow direction of the coolant, so as to regulate the engine temperature.
Working principle and function
The automotive thermostat tee is usually installed on the connecting pipe between the engine and the radiator. Its core component is a wax thermostat, which contains paraffin. When the engine starts, the water temperature is low, the paraffin is in a solid state, the spacer blocks the channel of the coolant into the radiator under the action of the spring, and the coolant directly returns to the engine, this state is called "small cycle". As the engine runs, the water temperature rises, the paraffin begins to melt, the volume expands, the spring pressure is overcome, and part of the coolant flows into the radiator for cooling, which is called "big cycle". When the water temperature rises further, the paraffin melts completely, and the coolant flows into the radiator .
structure
The structure of the thermostat tee consists of three main parts: the right line connecting the engine coolant output pipe, the left line connecting the automobile cooler input pipe, and the lower line connecting the engine coolant return pipe. Under the condition of paraffin wax, the spacer can be in three states: fully open, partially open and closed, so as to control the coolant flow to .
Common problems and maintenance
The thermostat failure usually has two phenomena: first, the thermostat can not be opened, resulting in high water temperature but the cooling tank fan does not turn; The second is that the thermostat is not closed, resulting in slow water temperature rise or high idle speed in the low temperature area. In order to ensure the normal use of the vehicle, the owner should replace the thermostat within the specified time or mileage according to the requirements of the maintenance manual .
The main function of the three-way tube of the automobile thermostat is to adjust the temperature of the engine to ensure that the engine runs at the best operating temperature.
Specifically, the thermostat tee helps the engine maintain a suitable operating temperature range by controlling the flow and direction of the coolant. When the engine temperature is low, the spacer in the tee tube will be closed or partially closed, so that the coolant circulates inside the engine, thus keeping the engine warm; When the engine temperature is too high, the compartment will open, allowing the coolant to flow to the radiator to cool down. In this way, the thermostat tee can automatically adjust the flow path of the coolant according to the actual working temperature of the engine to ensure that the engine will not overheat or undercool, thus protecting the engine and extending its service life .
In addition, the thermostat tee also has the following functions:
diverting coolant : The tee pipe can divert the coolant to different cooling circuits to ensure that all parts of the engine can be adequately cooled .
Engine protection : By precisely controlling the flow of coolant, prevent engine overheating or undercooling, reduce mechanical failures caused by temperature fluctuations .
Improve fuel efficiency : Keeping your engine within its optimal operating temperature range increases fuel efficiency and reduces energy waste .
