Thermostat housing for a thermostat of an engine cooling arrangement

Abstract

A housing for a thermostat includes a body, a cavity, at least one director member and at least one retainer member. The body defines an enclosure that receives coolant fluid. The enclosure is in fluid communication with a pump that pumps the coolant fluid to a sink for dissipating heat extracted by the coolant fluid. The cavity configured on body receives and holds thermostat that determines temperature of coolant fluid. The director member is configured on at least one internal wall of the enclosure and defines flow path of the coolant fluid so as to direct coolant fluid to thermostat and facilitate sufficient contact between coolant fluid and thermostat and the retainer member configured on the body is disposed around thermostat to prevent the coolant fluid from bypassing of the thermostat, thereby retaining coolant fluid in contact with thermostat to ensure precise sensing of temperature by the thermostat.

Description

FIELD OF DISCLOSURE[0001]The present disclosure relates to a cooling arrangement. More particularly, the present disclosure relates to thermostat housing for a thermostat used for detecting temperature of engine coolant used in an engine cooling arrangement.BACKGROUND[0002]An engine cooling system includes a coolant flow passage formed around a cylinder block of an engine for extracting heat generated in the engine during operation of the engine. The heated coolant is then circulated to a radiator with the help of a pump for dissipating the extracted heat, wherein the heated coolant is cooled down by air-flow and the cooled coolant is circulated back to the coolant flow passage to repeat the cycle of heat extraction from the engine. The flow of engine coolant to the radiator is governed based on temperature of the engine coolant detected by a thermostat. The thermostat should accurately detect the temperature of the engine coolant and allow or by-pass coolant flow to the radiator. C...
