Wax type thermostat for vehicles

Abstract

The invention discloses a wax-type thermostat for vehicles, which comprises a bracket, a casing, a reverse push rod with one end fixed on the bracket, an inner container, a plug and a paraffin filler arranged in the casing, and the paraffin filler is placed In the accommodating cavity formed by the plug and the inner tank seal, the free end of the anti-push rod extends into the accommodating cavity, and the free end of the anti-push rod protruding into the accommodating cavity is covered with a rubber sleeve, and the upper end of the rubber sleeve is along the The outer wall of the reverse push rod extends to the outside of the accommodating cavity, and the rubber sleeve is sealed with the inner wall of the through hole. It is characterized in that: the inner tank includes an inner inner tank and an outer inner tank, and the upper edge There are multiple inner heat conduction blocks in the circumferential direction of the inner liner, and outer heat conduction blocks corresponding to each inner heat conduction block are arranged on the outer liner, and the inner heat conduction block and the outer heat conduction block follow the Fitting or misalignment with the rotation of the outer liner. The invention provides a wax-type thermostat for vehicles with good response time consistency among various products.

Description

technical field [0001] The invention relates to the technical field of automobile engine cooling systems, in particular to a wax type thermostat for automobiles. Background technique [0002] The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes the water circulation range to adjust the heat dissipation capacity of the cooling system to ensure that the engine works within a suitable temperature range. The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine. [0003] At present, the commonly used thermostat is a wax-type thermostat. When the temperature of the coolant is lower than the specified value, the paraffin wax in the temperature sensing body of the thermostat is solid, and the thermostat valve closes the gap between the engine and the radiator under the action of a spring. The coolant returns to the engine thr...

AI Technical Summary

Problems solved by technology

Too fast or too slow response time is detrimental to the work of the thermostat, that is, the main valve of the thermostat is opened too late, which will cause the engine to overheat; temperature is too low

[0005] The paraffin composition and content of the respective wax-type thermostats, the difference in thermal conductivity of the thermostat shell, and the weight difference of the reverse push rod will cause differences in the response time of each wax-type thermostat. Therefore, Existing thermostats have poor response time consistency
