Problems solved by technology

[0004] The above-mentioned wax-type thermostat has the following problems: 1. The structure is complex, and the manufacturing process requires high requirements; 2. The paraffin wax of the wax-type thermostat often leaks
If the amount of paraffin leakage is small, the opening degree of the thermostat is not enough, the water temperature continues to rise, and finally the engine will overheat
If there is too much paraffin leakage, the thermostat will always be closed, the engine will overheat, and in severe cases, the engine will be burned

Abstract

The invention discloses a magnetic sensitive thermostat which comprises a shell, a first magnet assembly, a second magnet assembly and a push rod. The push rod is sleeved with the first magnet assembly and the second magnet assembly. An outer spring is arranged between the first magnet assembly and the second magnet assembly, and the magnetic function can be generated between the first magnet assembly and the second magnet assembly. A sealing assembly used for blocking a water outlet is arranged in the shell. The first magnet assembly and the second magnet assembly can eliminate the magnetic function at the preset temperature, so that the push rod drives the sealing assembly release blocking to the water outlet. Compared with an existing paraffin type thermostat, the magnetic sensitive thermostat has the following advantages that the manufacturing process and the control manner are simple; the effect of precise temperature control is achieved through the temperature sensing principle of a thermosensitive soft magnet, and sensitivity is high; and the risk of paraffin leakage is eliminated fundamentally.

Description

Technical field [0001] The invention relates to the technical field of thermal energy control, in particular to a magnetically sensitive thermostat. Background technique [0002] Automobile thermostat assembly is an indispensable part of automobile engine cooling system. In the cooling system of the automobile, the thermostat is opened and closed to make the coolant flow through the large or small cycle respectively, and finally achieve the purpose of rapid heating of the engine in cold weather or rapid heat dissipation of the engine in hot weather. [0003] Currently, wax-type thermostats are commonly used in automobile engine thermostats. The structure principle is: When the cooling temperature is lower than the specified value, the thermostat body's fine paraffin wax is solid, and the thermostat shell is closed under the action of the spring. When the coolant temperature reaches the specified value, the paraffin wax begins to melt gradually Turns into liquid, the volume begins...
