Problems solved by technology
It circulates in the engine cooling system to take away the excess heat energy generated during engine operation, so that the engine can run at normal operating temperature. When the coolant is insufficient, the engine water temperature will be too high, resulting in damage to engine parts , when the engine is running, the engine power changes greatly, that is, the engine heat load changes greatly, and the engine speed changes rapidly at the same time, so the demand for coolant is strict. However, the engine itself does not have a constant temperature control function. Quality cooling, timely replacement of coolant, so a constant temperature control device for engine coolant and its control method are needed

The invention discloses a constant-temperature control device for an engine coolant and a control method of the constant-temperature control device. The constant-temperature control device for the engine coolant is included and comprises a shell. A liquid inlet pipeline is arranged on the upper portion of the shell. A first electromagnetic valve is installed on the liquid inlet pipeline. A backflow pipeline is installed on the upper portion of one side of the shell. A second electromagnetic valve is installed on the backflow pipeline. A tee joint is installed at the end, away from the shell, of the backflow pipeline. A first connector of the tee joint is connected with the backflow pipeline. A third electromagnetic valve is installed on a second connector of the tee joint. The control method of the constant-temperature control device for the engine coolant is further included and includes a normal refrigeration control method S1, a coolant replacement control method S2 and a coolant addition control method S3. By means of the constant-temperature control device and the control method, the cooling effect of the coolant is improved, the temperature of the coolant is kept constant when the coolant is input into an engine, safety of the engine is protected, the cooling efficiency of the coolant is improved, energy is saved, the waste coolant is discharged in time, and the quality and cooling effect of the coolant are ensured.
Description
technical field [0001] The invention relates to the technical field of constant temperature control devices, in particular to a constant temperature control device for engine coolant and a control method thereof. Background technique [0002] Coolant is an integral part of a car engine. It circulates in the engine cooling system to take away the excess heat energy generated during engine operation, so that the engine can run at normal operating temperature. When the coolant is insufficient, the engine water temperature will be too high, resulting in damage to engine parts , when the engine is running, the engine power changes greatly, that is, the engine heat load changes greatly, and the engine speed changes rapidly at the same time, so the demand for coolant is strict. However, the engine itself does not have a constant temperature control function. Quality cooling, timely replacement of coolant, so a constant temperature control device for engine coolant and a control me...
